A waste gas recovery and purification system for tire reclaimed rubber production

Abstract

The invention relates to an exhaust gas recovery and purification system applied to tyre reclaimed rubber production. The exhaust gas recovery and purification system comprises a waste heat collector, an adsorption barrel, a dust removal tower, a debenzolization tower, a vapor generator, an oil-water separating tank, a first desulfurizing tower, a second desulfurizing tower and a chimney, wherein atube pass and a shell pass are arranged in the waste heat collector; a plurality of filter bag guiders, a filter bag, a filter plate and an ash collection tank are arranged in the dust removal tower; a medicine storage tank is arranged on one side of the first desulfurizing tower; a first spraying plate, a first interception layer, a second interception layer, a second spraying plate and a first water-gas separator are arranged in the first desulfurizing tower; a plurality of clapboards are arranged in the second desulfurizing tower; and a catheter is arranged on each clapboard. The exhaust gas recovery and purification system applied to the tyre reclaimed rubber production has a great exhaust gas purification effect and is beneficial to reducing resource waste and environment pollution.

Description

technical field [0001] The invention relates to a waste gas recovery and purification system used for tire reclaimed rubber production, and belongs to the technical field of rubber preparation. Background technique [0002] Tire reclaimed rubber is processed from waste tires, has a certain degree of plasticity, and can be reused. Reclaimed rubber can partially replace raw rubber for rubber products, which can save raw rubber and carbon black, and is also beneficial to improve processing performance and certain properties of rubber products. [0003] The production process of tire reclaimed rubber includes three processes: crushing, regeneration, desulfurization and refining. Under the combined action of plasticizer, softener or activator, oxygen, heat and mechanical shear, the waste rubber makes part of the molecular chain and crosslinking of vulcanized rubber. The process of point breaking. The softener plays the role of swelling and plasticizing. Commonly used are coal t...

AI Technical Summary

Problems solved by technology

[0004] During the production process of tire reclaimed rubber, a large amount of waste water containing phenol, ammonia, phosphorus, and waste gas containing sulfur dioxide and hydrogen sulfide will be produced, which will not only endanger human health, but also cause plant leaves to wither, reduce grain production or even fail, especially for tire reclaimed rubber production. The benzene pollutants produced in the process are internationally recognized carcinogens. Its chemical structure is not easy to degrade in the natural environment, causing persistent and serious pollution to soil, water and the atmosphere. However, the waste gas treatment and purification in the prior art The effect is not good, and it is difficult to recycle, causing waste of resources and environmental pollution
