An energy-saving rubber cracking equipment

Abstract

The invention relates to the technical field of rubber pyrolysis devices, in particular to an energy-saving rubber pyrolysis device. The energy-saving rubber pyrolysis device comprises a base, wherein six supporting legs are evenly distributed on the periphery of the lower side of the base, a heating base is arranged on one side of the upper portion of the base, a heating device is installed in the middle of the upper side of the heating base, the upper portion of the heating base is fixedly connected with a heating furnace, the heating device is communicated with the lower portion of the heating furnace, and the inside of the heating furnace is of a cavity structure. The heating device is communicated with the lower portion of the heating furnace, and the inside of the heating furnace is of the cavity structure, so that the heating device directly heats a pyrolysis bin, the energy transfer efficiency is higher, and the energy utilization rate is improved. A natural gas valve is arranged at the left end of the front side of the heating device, and a combustible gas valve is arranged at the right end of the front side of the heating device so that the proportion of natural gas and combustible gas can be freely adjusted as required, the combustible gas produced during pyrolysis can be used for completely replacing the natural gas in an ideal state to provide energy for the heating device.

Description

technical field [0001] The invention relates to the technical field of rubber cracking equipment, in particular to energy-saving rubber cracking equipment. Background technique [0002] After cracking waste rubber, gasoline, diesel, carbon black and other products can be produced through further processing, which not only realizes the harmless treatment of a large amount of waste rubber and other industrial waste produced in modern society, reduces environmental pollution, but also solves the increasingly serious The energy crisis provides a new way. [0003] At present, pyrolysis is an important step in the recycling of waste rubber. Under high temperature conditions, waste rubber is decomposed into hydrocarbons and carbon black. The hydrocarbons are recovered and processed into naphtha, diesel oil, etc. as fuel for takeaway. Most of the existing waste rubber cracking is a batch cracking process. The waste rubber is first put into the cracking reactor, then it is sealed, r...

AI Technical Summary

Problems solved by technology

In short, each batch of material treatment process includes at least five steps of charging, heating, cracking, cooling, and slag unloading. It will cause environmental pollution; second, the processing efficiency of the reactor is low, the energy consumption is large, and the energy utilization rate is extremely low; third, an open flame is used to directly heat the reactor, and the temperature adjustment in this process is inconvenient and fluctuates greatly, while When the temperature is high (generally around 500°C), the process of rubber decomposition will produce dioxins, which will seriously pollute the environment; fourth, the cracking process cannot be monitored at any time, and observation is inconvenient; fifth, the combustible gas produced during the cracking process cannot be effectively use up, resulting in a certain degree of waste

[0004] Utility model patent 201320839478.4 introduces "a complete set of equipment for continuous cracking of waste tire rubber particles". The sleeve-type reactor involved, the inner tube carries the reaction material, and the heat carrier passes between the jackets, realizing indirect heating and continuous cracking , but the disclosure of the technical content of transporting materials to the reactor and oil and gas treatment is insufficient, and the nitrogen seal of the raw materials is not realized. During the production process, the oxygen entrained in the raw materials and the oil and gas generated by cracking will mix to form explosive gas, which has potential safety hazards; The blended oil formed by direct cooling of oil and gas, which contains naphtha components, diesel components and residual oil components, because the thermal cracking products in the oil and gas contain dilute hydrocarbons, which are easy to condense and deteriorate, forming colloids and asphaltenes, which block the fractionation Towers and trays bring a lot of inconvenience to subsequent processing
