Device for recycling gas generated from cracking of waste tyres

Abstract

The invention relates to environmental protection equipment, particularly relates to equipment for recycling combustible gas generated from cracking of rubber, and specifically discloses a device for recycling gas generated from cracking of waste tyres. The device comprises a combustion furnace, a cracking furnace, a connecting pipe and electronic control devices, wherein a gas collecting device and a gas purifying device are connected with the cracking furnace; the gas collecting device comprises a gas storage tank and a buffering tank; a gas inlet of the gas storage tank is connected with the cracking furnace, and a gas outlet of the gas storage tank is connected with an exhausting device and the gas purifying device by a three-way joint; a total-pressure fan and the buffering tank are connected with the gas purifying device; a gas outlet of the buffering tank is connected with the combustion furnace; the electronic control devices are arranged in the total-pressure fan of the gas storage tank and the buffering tank. The gas recycling device has the advantages that the compositional structure is simple, the equipment investment is low, and a desulfurizing tower, the high-pressure fan and the buffering tank only need to be added into existing equipment; the use effect is obvious, and not only can the capital investment of the combustion furnace be saved, but also the combustion effect is good.

Description

technical field [0001] The invention relates to environmental protection equipment, in particular to equipment for recycling combustible gas after rubber cracking, in particular to a waste tire cracking gas recovery and reuse device. Background technique [0002] With the progress and development of society, mechanical tools are widely used, and various vehicles are successively used in various industries. And along with widely using all kinds of vehicles, the waste tires that eliminate replacement become very large a kind of idle resource. Since tires are composed of rubber, metal or non-metallic reinforcements, etc., some of them were used outside the repair industry of daily necessities in the era when the amount was small, and most of them were abandoned or burned. This treatment method not only pollutes the environment but also wastes natural resources. In the prior art, there are technologies and equipment for decomposing and utilizing waste tires. The process is to ...

Problems solved by technology

[0003] However, in the prior art, various chemical raw materials are produced after tire cracking, and combustible gases are also produced incidentally.

Due to the different stages of the chemical reaction, the gas produced in the cracking process has different amounts of gas produced by the reaction, so the pressure of the gas produced is unstable, and most of the gas pressure is low, so it cannot be directly used in the combustion furnace; moreover, due to the mixed composition of the gas produced Complex, especially high sulfur content, does not meet environmental protection standards, so these mixed gases cannot be directly used

Therefore, there is a lack of complete and effective gas recovery and utilization devices in the existing technology

At the same time, the existing technology will also produce new pollution to the environment in the tail gas treatment. Although the amount is not too large, it still cannot be processed and allowed to pollute the environment.
