Unique Technology Advantage
1,Advanced Energy Saving Technology of Cycle Heating Internal and External
The basis of energy saving technology lies in:the fuel is directly heated in the "internal reactor",which can transfers heat energy equally to the reactor all around in 360 degree. The heating efficiency is two or three times more than the way of heating at the bottom of the reactor only.
Meanwhile, the material is distributed on the surface of the "internal reactor in 360 degrees ", with large area of heat absorption, and the heat energy is fully absorbed in the "internal reactor ". At the same time, the heat energy of the "internal reactor" is circulated to heating stove of "external reactor"  and heat to reactor. The heat energy is transmitted to the "material preheater" again after secondary utilization and then preheat materials.
Thrice use like this, especially both heat absorption and heat release evenly all around of internal reactor, heat utilization increases 3-4 times.
2,Advanced Continuous Operation Technology
Continuous production must be completed jointly in three basic links, namely uninterrupted feeding, continuous slag discharge and uninterrupted oil and gas discharge. In particular, continuous feeding and continuous slag discharge are two key technologies, which are the core technologies related to the real uninterrupted production.
Because feeding can not be continuous if slag could not be discharged in time. Then it can not realized continuous running if without continuous slag discharge.
The key technology lies in our design of "automatic gas seal feeding, slag discharge method" which belongs to our company's proprietary and patented technology. Thus,in high temperature condition,feeding material can be push into reactor,then slag discharge out of reactor,meanwhile hydrocarbone can continuously fractionate out of the reactor to  achieve completely continuous production of feeding,slag discharge,oil producing in one production line,greatly improving the production efficiency and environmental protection effect.
3,Advanced Automatic Decoking Removal Technology
At present, the biggest problem for continuous production of rotary reactor is thick coke will be formed continuously when feeding materials are affected by high temperature in the reactor, which not only makes the reaction unable to proceed, but also damages the equipment quickly. The company invented a series of automatic decoking devices, such as"Plate decoking method";" Shoveling pushing decoking method";" Friction decoking method", etc,which can constantly remove the coke in the reactor to ensure the continuous reaction and greatly extend the life of the equipment, completely solve the problem of materials (especially plastic and liquid raw materials) in the running of reactor.
Important data:Oil content of carbon black from our plant:0.3%. Good quality carbon black sells at good price.
4,Advanced Catalytic Cracking Technology in Low Temperature
Generally, low technology enterprises adopt simple heating pyrolysis method for oil refining, and many recombinant fractions higher than the molecular weight of diesel 220 which will fail to be pyrolyzed and cannot be converted into qualified fuel oil. Our company adopts "Precious Oil" series of conversion agents to depolymerize macromolecules and harmful substances in reactor. At the same time, deep cracking agent was used in the special fixed bed catalytic tower to further crack macromolecules and maximaly improve the oil recycling rate. Moreover, the end oil has better quality with less colloid and asphaltene. Due to the effect of catalyst, the temperature of pyrolysis is reduced, there is no coking in the equipment, so the quality of carbon black good.
5,Advanced Sulfer Removal Technology
In the tire reaction,with new sulphur-fixative added into the reactor, sulfide of feeding material will solidify through complexation and gasified sulfide will be absorbed, thereby to prevent sulfide emission into the end oil and around air.
6,Advanced Sulfer Removal Technology
In order to ensure the accurate and smooth production operation , the relevant device key parts are installed digital instruments which will centralized manage of all data,thus will highly improve the controllability of operation and timely problems processing .
Environmental Protection and Safety
(1) No dust. Main pyrolysis system operate in closed situation (reactors) in production.
That is to say safe operation in a totally closed equipment.
(2) Non-condensate gas(mainly C1-4)
The non-condensed gas recycled can transfer into heating system itself to support the continuous production. If there is a problem in the system, turn off the heater, the heating source can be cut off instantly to ensure the safety of the system.
(3) Double insurance secutiry device and alarm device are installed on the each key parts.
