Speed-increase type concurrent flow rotating spraying type gas washing tower

Abstract

The invention discloses a speed-increase type concurrent flow rotating spraying type gas washing tower, and belongs to the technical field of washing towers. The speed-increase type concurrent flow rotating spraying type gas washing tower comprises a vertically-arranged air inlet flue and an induced draft fan, gas introduced in the air inlet flue by the induced draft fan is blown from top to bottom, a rotating spraying mechanism is arranged inside the air inlet flue, a rotating spin-drying mechanism is arranged at the lower portion of the air inlet flue, a gas-liquid separating channel is arranged at the bottom of a rotating spin-drying cylinder of the rotating spin-drying mechanism, the gas-liquid separating channel is communicated with an air outlet flue, and a spraying liquid collecting drainage opening is formed in the bottom of the gas-liquid separating channel. Due to the gas and spraying liquid concurrent flow design, the gas flowing resistance is lowered; on the basis of the atomization rotating spraying mode, effective contact between the spraying liquid and gas is increased, rapid gas-liquid separation is achieved by means of the rotating spin-drying mode, and a series of problems that an existing washing tower reaction is not sufficient, the gas flow speed is low, the gas exhaust humidity is high, and the tower structure is huge are solved fundamentally.

Description

technical field [0001] The invention relates to a gas scrubber, more specifically, to a speed-increasing type downstream rotary spraying gas scrubber. Background technique [0002] The reaction process involving gas reaction and liquid phase conversion in the existing chemical industry and environmental protection engineering will use a large number of so-called gas scrubbing towers (scrubbing towers). The scrubber is a kind of gas purification treatment equipment, which is widely used in the pretreatment of industrial waste gas purification and dust removal. For the coal gasification process, coal gas scrubbing is inevitable, and this unit operation is used in any coal gasification technology. Because its working principle is similar to the washing process, it is named scrubber. [0003] The gas washing reaction tower is used for the liquid medium to absorb certain substances in the gas phase state and react with them, and then re-separate the gas and liquid, and finally ...

Problems solved by technology

[0010] The purpose of the present invention is to overcome the above-mentioned deficiencies existing in the existing scrubber, and to provide a speed-increasing type downstream rotary spraying gas scrubber. By adopting the technical solution of the present invention, the downstream design of the gas and the spray liquid reduces the The gas flow resistance improves the gas flow speed, and with the atomization and rotary spraying method, the effective contact between the spray liquid and the gas is increased, and the reaction efficiency is improved. At the same time, the water mist is quickly discharged by the rotary drying method, realizing Rapid gas-liquid separation, effectively avoiding the escape of spray droplets, and fundamentally solving a series of problems such as insufficient reaction of the existing scrubber, low gas flow rate, high moisture content in gas discharge, and large tower structure size
