Operation method of waste tire pyrolysis reaction furnace feeding system

Abstract

The invention relates to the technical field of environmental protection, in particular to an operation method of a waste tire pyrolysis reaction furnace feeding system. The operation method is characterized in that a rotating ball assembly is connected with a middle bell jar through a sling chain, the middle bell jar is controlled to move downwards, rubber blocks are driven by gravity to fall into the tail-section hopper body, the rotating ball assembly acts immediately when the stacking amount of the rubber blocks reaches the volume of the tail-section hopper body, and the middle bell jar moves upwards to be matched and tightly attached to the middle bell jar base to form a sealing face; the multi-stage steam ejector assembly is started, steam fluid works, steam adiabatically expands ina spray pipe, the flow speed at an outlet of the spray pipe is increased, meanwhile, the pressure is reduced, inert tail gas in a rubber block gap of a tail-section hopper body is drained and extracted, after the vacuum degree is controlled to range from 1000 Pa to 1300 Pa, the multi-stage steam ejector assembly stops working, and a pull rod assembly is connected with a lower bell jar. The lower bell jar is controlled to move downwards, the rubber blocks are driven by gravity to fall into the vertical pyrolysis tower body, and continuous production is achieved through sequential circulation and reciprocation.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an operation method of a feed system of a waste tire pyrolysis reaction furnace. Background technique [0002] Waste tires are common solid waste pollutants. People use many ways to recycle them to achieve harmless treatment. Among them, the preparation of fuel oil and carbon black by pyrolysis of waste tires is one of the solutions. The pyrolysis of waste tires to prepare fuel oil , The process conditions of carbon black are completed in anoxic or vacuum environment. Chinese invention patent (patent application number 201822203253.5, patent name is a hydraulic automatic feeder for tire cracking equipment) discloses a hydraulic automatic feeder for tire cracking equipment, which is characterized in that the bottom of the frame (1) There are support wheels (2), the hydraulic cylinder support frame (4) is fixed on the top left end of the frame (1), the feeder oute...

AI Technical Summary

Problems solved by technology

[0003] Existing technology 1 By setting support wheels, flanges, observation decks and hydraulic cylinders, the problem of slow and difficult feeding of traditional tire cracking equipment is solved, and the hydraulic cylinder is used to send waste tires into the pyrolysis furnace, realizing automatic Feed, but did not solve the problem of how to isolate the air in the process of feeding, so as to avoid the oxidation reaction in the pyrolysis process of waste tires, resulting in a decrease in the yield of cracked oil and an increase in the asphaltene component of the cracked oil; prior art two There is a rotating shaft in the center of the inner cylinder, which realizes the continuous feeding and cracking of the whole tire of waste tires. The inner cylinder is equipped with a sealed heat-conducting filler to solve the problem of isolating the air during the feeding process. This kind of feeding is similar to a drum. The method of sealing and sealing is not reliable, because the sealing surface of the dynamic seal of the drum will be deformed at high temperature, the sealing packing does not have the compensation function, there is still the possibility of leakage, and the waste tires will be seriously deformed after being damaged, which is extremely irregular Filling the drum with waste tires will cause the drum to be stuck
