Spraying system for waste gas purifying tower

Abstract

The invention discloses a spraying system for a waste gas purifying tower. The spraying system comprises a spraying main pipe (1) and is characterized in that spraying branch pipes (2) are evenly built on the spraying main pipe (1), spiral sprayers (3) are evenly arranged at the bottom of the spraying branch pipes (2), and water flow entering the spiral sprayers (3) from the spraying branch pipes (2) produces layered spraying by hitting a spiral layering interface. Due to the arrangement of the spiral sprayers, the water flow entering the spiral sprayers from the spraying branch pipes produces layered spraying through hitting the spiral layering interface, the streamlined design from an inlet to an outlet in a cavity of the spiral sprayer leads to the minimum resistance coefficient, so that liquid blockage is reduced to the greatest extent, the liquid reaches the maximum flow on a pipeline with specified size, in addition, the wear resistance, the corrosion resistance, the fogging property, and the anti-blocking property of the spiral sprayer are better than those of a tobacco pipe sprayer, the cost is low, the mass production can be carried out easily, and the spraying system is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of waste gas collection and treatment, in particular to the technical field of waste gas collection and treatment produced during sewage treatment, and specifically relates to a spray nozzle for waste gas purification towers with a small number of nozzles, a relatively large flow rate of nozzle monomers and a large spray area. shower system. Background technique [0002] Waste gas is generated during sewage treatment. To protect the environment, it needs to be collected and treated. In the prior art, waste gas purification towers are generally used for collection and purification. The existing exhaust gas purification tower uses a pipe nozzle. The solid nozzle of the conventional pipe nozzle has a diversion cone inside, allowing the liquid to flow in a clockwise or counterclockwise direction through the diversion of the cone, and due to the effect of water pressure Make the liquid generate centrifugal force...

AI Technical Summary

Problems solved by technology

The existing exhaust gas purification tower uses a pipe nozzle. The solid nozzle of the conventional pipe nozzle has a diversion cone inside, allowing the liquid to flow in a clockwise or counterclockwise direction through the diversion of the cone, and due to the effect of water pressure Make the liquid generate centrifugal force, thereby producing a cone-shaped spray; the nozzle flow rate and spray area of ​​the pipe nozzle are small, and the number of nozzles needs to be equipped with a high cost; the waste gas and wastewater contain a large amount of impurities, and the pipe nozzle is easy to block, requiring Clean and replace frequently
