Problems solved by technology

[0004] In the prior art, there is a method to judge whether sewage needs to be discharged by detecting the salt content in sewage, but this kind of method needs to send the sampled water to the laboratory for testing, which takes a long time, costs high, and the detection is not continuous, so it cannot be passed in time Salt content index for sewage discharge

Abstract

The invention relates to an automatic blowdown control device and method for a cooling tower, and the control device is provided with two sensors for monitoring the characteristic ion concentration of circulating water in a water collecting tray and replenishing clean water, calculating the ratio of the characteristic ion concentration value of the circulating water to the characteristic ion concentration value of a clean water source, and comparing the ratio with a sewage discharge threshold value. Whether pollution discharge is needed or not can be judged, and the same control requirement can be met in different initial water quality environments; the chloride ions are adopted as the indication index of the salt content of the circulating water, online monitoring of the chloride ion concentration can be achieved, accurate judgment can be made in time when pollution discharge is needed, sampling and sending to a laboratory for detection are not needed, time and labor are saved, and the cost is low.

Description

technical field [0001] This patent belongs to the technical field of cooling towers, and in particular relates to an automatic sewage discharge control device and method for cooling towers. Background technique [0002] In order to ensure the water quality of the circulating cooling system of the cooling tower and avoid excessive concentration, it is necessary to discharge part of the sewage regularly or in real time. Regular blowdown of the cooling tower mainly refers to removing the silt, moss and corrosion products of the cooling tower water tray, reducing the weight of the water tray itself, preventing the blockage of the return water pipe, reducing the turbidity rate of the circulating water, and strengthening the cooling effect of the cooling tower. Cooling tower blowdown can alleviate obstacles in the tower, reduce the blockage of cooling tower filling and spraying system, and directly affect the cooling tower cooling; so the quality of cooling tower circulating water...
