Sand protecting and dust removing device for cooling tower

Abstract

The invention relates to a sand protecting and dust removing device for a cooling tower, which comprises a spraying nozzle and a sand filtering pool, wherein the spraying nozzle is arranged at the upper side of the air inlet of the cooling tower, and the spraying direction of the spraying nozzle is interlaced with the air intake direction of the air inlet of the cooling tower; the sand filtering pool is arranged at the lower side of the cooling tower and corresponds to the position of the spraying nozzle; a water collecting pool is arranged at the inner side of the sand filtering pool, and a water discharging pool is arranged at the outer side of the sand filtering pool; and sand filtering screens are respectively arranged between the water collecting pool and the sand filtering pool and between the sand filtering pool and the water discharging pool. The sand protecting and dust removing device for the cooling tower, which is provided by the invention, has simple structure, can thoroughly protect sand and remove dust, can be used conveniently, and can not influence the load of a draught fan.

Description

technical field [0001] The invention relates to a cooling tower, in particular to a sand prevention and dust removal device for a cooling tower. Background technique [0002] A cooling tower is a device that exchanges heat with circulating cooling water through cold air. During use, it is necessary to continuously introduce air from the outside to perform heat exchange inside the cooling tower. In some areas where sand and dust weather is common, sand and dust can easily enter the system through the air inlet, causing great damage to the equipment and affecting its service life. Therefore, it is particularly important to perform dust-proof treatment on the air inlet. In order to solve this problem, people often finish by arranging sand filter screen at the air inlet, as the Chinese patent that publication number is CN201266022 discloses a kind of cooling tower anti-sand and dust removal device. The device includes a sand control device installed at the air inlet of the coo...

AI Technical Summary

Problems solved by technology

[0003] The present invention is mainly to solve the problem that the anti-sand and dust-removal device of the cooling tower in the prior art has poor effect, and the processing ability for some small dust is very poor, and some sand-proof and dust-removal devices also need to increase the load of the air-inducing device On the one hand, it causes energy waste, on the other hand, it reduces the technical problems such as the service life of the device, and provides a cooling tower sand prevention and dust removal device with simple structure, thorough sand prevention and dust removal, convenient use, and does not affect the load of the air induction device.
