Problems solved by technology

However, due to the operation of the rubber mixing process and the size of the equipment, the existing rubber mixing waste gas collection has the characteristics of large air volume, low concentration and poor efficiency.
Through the test of the VOCs emission concentration in the rubber mixing workshop of the domestic tire factory, it was found that the VOCs concentration at the discharge port of the master batching process was only less than 50ppm, which brought a huge load burden to the subsequent exhaust gas collection mechanism and directly caused a high Initial investment and operating costs
The treatment of this low-concentration, high-volume organic waste gas is an industrial problem, and there is currently no cost-effective solution

Abstract

The invention provides an exhaust gas concentrating mechanism. The exhaust gas concentrating mechanism comprises a closed chamber and a controller, wherein an exhaust gas source and a gas concentration sensor are arranged in the closed chamber, dedusting equipment and a circulating fan communicate with the closed chamber in sequence, the circulating fan communicates with a first branch pipe and asecond branch pipe separately, and an air exhausting valve is arranged on the first branch; an air returning valve is arranged on the second branch, and communicates with the closed chamber; and the controller is connected with the gas concentration sensor, the air exhausting valve and the air returning valve separately. The exhaust gas concentrating mechanism has the beneficial effects that for the characters of large air flows and low concentration of exhaust gas, a low-concentration organic exhaust gas continuous exhausting mode is turned into a high-concentration exhaust gas intermittent exhausting mode, so that the treatment load of subsequent purifying equipment is greatly reduced, meanwhile, the purifying efficiency of the equipment is improved, energy is saved, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of gas purification, in particular to a waste gas concentration mechanism, a waste gas collection system and a working method thereof. Background technique [0002] Rubber mixing flue gas contains a variety of toxic and harmful pollutants, mainly stench, dust and volatile organic compounds (VOCs). Edema, and even death by suffocation. Therefore, the task of efficiently collecting and treating waste gas in the rubber mixing section is imminent. [0003] At present, the purification methods of organic waste gas mainly include absorption method, adsorption method, oxidation method and biological method. However, due to the operation of the rubber mixing process and the size of the equipment, the existing rubber mixing waste gas collection has the characteristics of large air volume, low concentration and poor efficiency. Through the test of the VOCs emission concentration in the rubber mixing workshop of the...
