Gas recycling system of recirculation air pulverizer

Abstract

The gas recovery system of an air recycling pulverizing device comprises a tail gas recovery circuit, an air leak branch, a compressor and an exhaust duct, and is characterized in that the air leak branch is connected with the tail gas recovery circuit, the compressor inlet is connected with the outlet of the air leak branch, the compressor outlet is connected with the tail gas recovery circuit, and the exhaust duct is connected with the air leak branch. The invention gives a resolution to the environment pollution caused by micro powder or harmful gas contained in tail gas, and recovers powder to the utmost extent through utilizing recycling means, thus greatly reducing gas emission and decreases the economic losses caused by direct emission.

Description

(1) Technical field [0001] The invention relates to a circulating air grinding device, in particular to a gas recovery system of the circulating air grinding device. (2) Background technology [0002] The gas recovery system of the circulating air grinding device is the tail gas treatment part of the circulating air grinding device. The circulating air grinding device uses the high-speed wind circulating inside the device to continuously carry the materials that have been ground into powder from the grinding equipment To the receiving device, the high-speed air after the powder is separated by the receiving device is sent back to the grinding device through the high-pressure fan to repeat the above process. Due to the flammable and explosive characteristics of the powder, the entire circulating air system must be protected by special gases. , and maintain a certain proportion of special gas content, because the entire circulation system leaks air, the air leaking into the sy...

AI Technical Summary

Problems solved by technology

The first problem is that although the above-mentioned tail gas reaches the environmental protection emission index, the trace powder or harmful gas contained in the tail gas still pollutes the environment; the second problem is that the above-mentioned tail gas contains a large amount of special gas, and the amount of special gas The cost is very high, and direct discharge will cause greater economic losses

The current methods to solve this problem are all focused on adopting different tail gas treatment systems to reduce pollution and other measures. Although these methods can solve the problems caused by tail gas emissions to a certain extent, they cannot change the environmental pollution and special gas emissions. economic loss, but also increased equipment and investment
