Automatic control method for treating cooling circulation water system by ozone

Abstract

The invention discloses a self-control system of ozone disposing cooling circulating water system, which is characterized by the following: detecting the thermal resistance of foul of circulating water in the system, the etching rate and micron index; comparing the data with the preset multi-parameter database; judging whether the condition of the circulating water is etching or fouling; providing convenience to do self-operating order of the system; directing the discharge of the circulating water and pump-valve operation of the water supplementation according to the judgment of the water condition; adjusting the real-time ozone happening quantity; making the circulated water quality satisfy the standard; increasing the circulating times of disposed water.

Description

technical field [0001] The invention relates to an automatic water treatment method, in particular to an automatic control method for an ozone treatment cooling circulating water system. Background technique [0002] Scaling and corrosion are the most common problems in heat exchange equipment systems using circulating cooling water, which will endanger the operation of the equipment. The open cooling tower continuously evaporates water to take away heat during the working process, which not only concentrates many substances in the water, but also continuously brings pollutants, dust, microorganisms, etc. in the atmosphere into the water. If the water quality of the circulating cooling water cannot be controlled, It will soon reduce the working efficiency of heat exchange equipment (various types of refrigerators, air compressors, etc.), blockage of pipelines, greatly increase energy consumption, cause corrosion of equipment, shorten service life, and cause great economic lo...

More importantly, because the supplementary water quality often changes in practice, seasonal changes and changes in working conditions will directly affect the determination of the POSI value

For example, the conductance of tap water in this city varies greatly, resulting in changes in the preset POSI value. Moreover, when using water from other sources as supplementary water, there is no guarantee that the conductance will always be stable and other components will remain unchanged. Therefore, In these cases, simply using the POSI calculated under steady conditions as a measure of fouling propensity will not be reliable
