PART1. Drying Pretreatment System

Dryer
Dryer

Drying Drum

The drying drum rotates under the work of the driving device, and the heat supplied to the drum is burned by the main and auxiliary furnaces of the main engine. The raw material absorbs heat in the drum, and the moisture in the material starts to evaporate, thereby reducing the moisture content of the material. The drum rotates to remove the material. The gravitational force of the external fan can extract most of the undesirable impurities, dust, etc., to provide good raw materials for the carbonization furnace, and greatly improve the processing capacity of the carbonization host and the quality of charcoal.

Breaker Shaft

The agitating and advancing structure design of the breaker shaft has high drying efficiency and large drying capacity. The breaker shaft breaks and raises the material, and the material curtain wall like a “sandstorm” exchanges heat energy with the hot air, and the hot air is induced by the fan. The negative pressure must pass through the curtain wall to be discharged from the machine. Fully dry the wet materials before discharging the materials from the machine. The pressure of the purification equipment in the later process is very small, because the dust of the waste heat exhaust gas, carbon monoxide and the wet material adhere to the material during heat exchange, and the material has a certain degree of purification and filtration. Changing the speed of the dispersing shaft can control the speed of the motor by means of frequency conversion control to adjust the speed of the dispersing shaft, adjust the dust concentration raised during the drying process, to improve the quality of charcoal.

Main Carbonization Furnace

The main furnace rotates under the operation of the driving device, and the raw materials absorb heat in the main furnace. After reaching the pyrolysis temperature, the pyrolysis of biomass starts to produce solid charcoal and combustible gas.

Main Carbonization Furnace
Main Carbonization Furnace

The main furnace is the core component of the entire biomass pyrolysis equipment. The quality of its production and whether the design is reasonable directly affect the normal operation of the entire pyrolysis equipment, as well as the safety of personnel and equipment in production.

The main furnace adopts a double-cylinder structure, that is, the “one-fire two-step method” for pyrolysis, and the outer layer is deeply heated, so that the biomass can produce high-temperature dry distillation reaction in a relatively closed environment inside, and the inner cylinder further evaporates the material in a relatively high-temperature environment. Therefore, it can ensure that the charcoal content of the produced biomass meets the ideal requirements. The material does not contact the flue gas and is not polluted by hot air. Compared with the single-layer external heating structure, the heat utilization rate is more than doubled, and the thermal efficiency of the equipment reaches 70%-90%. The heating zone uses 310S stainless steel to prevent the equipment from overheating and deformation. It adopts a double-return heating structure. Any traditional equipment does not have this structure. There are technical blind spots in the improvement, and the user has a very high praise rate.

Casing

The main function of the casing (the inside needs to be filled with castable or ceramic modules) is to keep warm, reduce the heat loss of the pyrolysis reactor in the heating process, and reduce the fuel consumption. The casing is generally composed of a pair of upper casing and 2 lower casings. The casing is one-piece, and the upper and lower casings are connected by bolts, which is convenient for installation.

PART4. Combustible Gas Condensing System

Plate Condenser

Its function is to perform preliminary cooling of the combustible gas from the main furnace so that the combustible gas carries sundries, the dirt after cooling and condensation, and the liquid oil fall into the bottom of the condenser to be discharged, which can reduce the intake pipe in the rear tube condenser clogged.

Plate Condenser

Tube Condenser

The function of the tube condenser is to convert gas or vapor into liquid, and transfer the heat in the tube to the cooling water outside the tube in a very fast manner. The working process of the condenser is a process of exothermic heat. The design of the condenser is directly related to the rate of charcaol.

Tube Condenser
Tube Condenser

The condenser of the biochar making machine has the characteristics of simple structure, convenient maintenance, large cooling area, etc., and is widely used in the petrochemical industry. It uses water as the cooling medium to transfer heat.

During the flow of combustible gas, the cooling water flows into the condenser from the water inlet at the bottom under the action of the cooling water circulating pump. During this process, the heat of the combustible gas is transferred to the cooling water, and the hot water is discharged from the water outlet and enters the water inlet of the cooling tower. Under the action of the heat dissipation tower, the heat in the cooling circulating water is discharged, so that the temperature of the cooling circulating water is within a certain range to ensure the normal operation of the condensing system, and the circulating cooling water is always clean.

Hydro-seal

The hydro-seal is to adjust the internal pressure of the combustible gas pipeline and the main furnace through the pressure of the water. A branch pipe is drawn from the combustible gas pipeline and inserted about 6-10 cm below the water surface. When the internal pressure is too high, it will overcome the pressure of the water to leak out, and at the same time, the branch pipe cannot be inserted below the water surface. Too-low water pressure increasing will increase the pressure relief pressure and reduce the safety of protection.

PART7. Other Parts

Cooling Tower

The cooling tower is a device that uses the contact of water and air to dissipate waste heat generated in industry or in refrigeration and air conditioning through evaporation. The process of cooling water in a cooling tower is a process of heat and mass transfer. The cooled water is distributed to the filler inside the cooling tower with nozzles, water distributors or water distribution trays, which greatly increases the contact area between water and air. The air is brought into the cooling tower by the fan. Part of the water absorbs heat and vaporizes under isobaric conditions, so that the temperature of the surrounding liquid water drops.

Cooling Tower
Cooling Tower

The basic principle is: after the dry air is drawn by the fan, it enters the cooling tower from the air inlet network; the high temperature water molecules with high saturated steam partial pressure flow to the low pressure air, and the hot and humid water self-seeding system is sprinkled into the tower. When water droplets contact air, on the one hand, due to the direct heat transfer between air and water, on the other hand, due to the pressure difference between the surface of water vapor and air, evaporation occurs under the action of pressure, that is, through contact with unsaturated dry air The heat transfer takes away the sensible heat of the water, and part of the water evaporates to remove the submerged heat in the water, so as to achieve the purpose of cooling the cooling water.

Electric Control System

Electric control cabinet is the control center of the entire carbonization system. It controls the switching and operation of each motor in the system, and displays the temperature and pressure of key parts at the same time, providing data for production operations.

Electric Control System
Electric Control System

The internal control circuit of the electric control cabinet has been connected before the equipment leaves the factory. You only need to connect the power circuit and the transmission signal circuit according to the marks on the terminal.

Induced Draft Fan

The principle of the induced draft fan is the fan impeller inside the fan rotates at a high speed when the fan is working, so that the air in the fan shell generates centrifugal force and is thrown away from the fan impeller, and is “pressure sent” out of the fan through the air outlet; The air is thrown out to produce “negative pressure”, so “new air” is constantly replenished from the air inlet, which constitutes the normal working state of the fan.

Induced Draft Fan
Induced Draft Fan

When the induced draft fan is working, it discharges the hot air flue gas generated in the furnace and maintains a certain negative pressure in the furnace, which is also called a suction fan. The air inlet of the induced draft fan has its own air valve. The function is to adjust the effective flow area of the air inlet by adjusting the different gears of this valve, thereby adjusting the flow of hot air. Generally adjust to the middle gear. The principle is that the faster the hot air flow rate, the less heat the hot air transfers to the main furnace.
