Multi-stage spray treatment device for waste gas of printing and dyeing setting machine

Abstract

The invention discloses a multi-stage spray treatment device for waste gas of a printing and dyeing setting machine. The multi-stage spray treatment device comprises purification chambers including a primary purification chamber and a secondary purification chamber, wherein the interior of the primary purification chamber is divided into multiple layers of purification areas through partition boards; the partition boards are horizontally arranged in parallel in a staggered manner; an all-directional fine atomization area is arranged above a second air inlet of the secondary purification chamber; a water curtain wall blockage area is arranged at the upper part of the fine atomization area; a plurality of tower plates are vertically arranged in the water curtain wall blockage area, a plurality of spray nozzles are placed between the inner wall of the water curtain wall blockage area and the tower plates and between every two tower plates in a staggered manner, and the outlet directions of the spray nozzles are opposite; the spray nozzles spray airflow and water to the inner wall of the water curtain wall blockage area or the tower plate walls simultaneously to form a water curtain wall, so that liquid drops flow downwards along the tower plate walls or the inner wall of the water curtain wall blockage area, and the purified gas runs upwards continuously. According to the invention, the spray mechanism has three different effects, so that the dust collecting efficiency is improved, the production cost is reduced, and the multi-stage spray treatment device can be widely applied to treatment of waste gas of the printing and dyeing setting machine.

Description

technical field [0001] The invention relates to a multi-stage spray treatment device for waste gas of a printing and dyeing setting machine. Background technique [0002] As people become more and more aware of environmental protection and their awareness of environmental protection continues to increase, many production-oriented enterprises have consciously increased corresponding pollution control equipment, greatly reducing the resentment of residents living near the factories. [0003] However, due to the expansion of the production capacity of the enterprise, the emission of exhaust gas has also increased a lot, and the original exhaust gas treatment equipment seems to be stretched. National emission standards, and even the waste gas treatment equipment of many enterprises have become decorations. As a result, the residents around the factory were once again harassed, and some residents even suffered from severe respiratory diseases due to long-term exposure to this ki...
