Dear friends of Beston, I’m Fredo WANG and Today is 19th November of 2020. Today we are at our running site for pyrolysis. What we have here are 5 sets of 12 tons/day pyrolysis units. In total 60 tons/day in capacity. The raw materials we are taking are oil sludge. Let’s take a look inside.
Now we are in the plant. You can see all of our 5 machines are lined up one by one. The pyrolysis system we have consists of mainly three parts- the reacting system, the condensing system and de-dusting system. In our case only the reacting system is inside the warehouse, the other two systems we locate outside for good. Let me explain the process in detail.
Let’s first start with feeding. The feeding is done by a crane dropping material into the hopper, the hopper is connected with an auto screw feeder feeding into the reactor. The feeding process will take about 1 hour, and after that we will start the burner for preheating. The preheating process will take about two hours when the reactor temperature reach to 180 degrees. That’s when the reaction will begin. This Burner can be fueled by diesel, LPG, natural gas, or of course pyrolysis oil.
Dear friends, what we have here is the feeding. Now we are feeding the oil sludge into the system. It is done by the crane take a tonnage bag and dropping into the hopper we have. And after the hopper it’s connected with the auto screw feeder. It will feed into the system.
Once the reaction starts, the oil gas will be generated from the reactor. Then it will first arrive at the manifold. The manifold is to separate the heavy element from the light oil gas. Then it will be reserved in the oil sludge tank. You can see how it looks from here. While the light oil gas will travel to the next part, that is the condensing system.
The condensing system we have are the vertical condensers. From here we have three condensers with two oil tanks for each unit of machine. From here the oil gas will be condensed and liquified, the oil will be reserved into the oil tanks. It will be later transported into a bigger tank like this.
After the condensing we still have some non-condensable gases left. We call it Syngas. The Syngas will first come to the hydroseal. This Hydroseal is used to purify the gas also to prevent the backfire from happening. Then the syngas will be direct back to the furnace to be burned as a heating source. The utilization of the syngas makes the system self-sufficient and environmental friendly.
The cooling water circulation of all 5 machines are supplied from here, this cooling water pond. The cooling tower we have here can process water of 80 cubic meters per hour.
Here we are at our oil sludge area. These oil sludge are coming-in in tanks, in the form of liquid. We also have oil sludge coming-in in tonnage bag, that is in the form of solid. Our system takes the material regardless of its forms. The oil yield of such is normally around 30-40%. If you can send some samples to us, we would love to test it out for you.
After the reaction the system will get cold down. Then the carbon black from the reactor will be discharged through our auto cooling discharger. It will then be reserved into the ash tank. The carbon black will be later used for asphalt, cement or brick industries.
We also have a big ash tank to collect carbon black from multiple units. Then when the truck comes we will put the carbon black into tonnage bag and transport it out.
What we have here is the waste combustion chamber. It is to burn out the surplus syngas that generated from the system that we can not use. This is one of the most important safety factors that is for the operation. Also from the tower itself the de-dusting system is included.
At last we arrive at our de-dusting system. The de-dusting system is to treat the hot smoke generated from the process. In our case we build this one huge de-dusting tower to serve the all 5 units of machines. It includes the flue condensers, the different filters and also the water spray. Only after the treatment the exhaust can be released without a problem.
Thank you all so much for taking this tour with me. If you are looking for a business of so profitable so lucrative like this, do not hesitate to contact me. I’m Fredo WANG, I work for Beston machinery. Thank you
Our carbonization reactor, where it matches with the combustion chmaber, we use the stainless steel on these two parts in order for it to withstand a high temperature after many years of using. The design of our reactor will adapt to our patented double tube design, so that the material can go inside and come out from the same side, and constantly feeding and constantly discharging.
In Beston we keep developing cutting edge technologies to meet with our customers’ demand. Over here we have the controlling system of the carbonization. This PLC cabinet is made with two doors design and siemens screen on top. It will control all the way from the drying system to the reacting system to the de-dusting system.
