Novel cooling tower circulating water treatment system

Abstract

The invention discloses a novel cooling tower circulating water treatment system. The novel cooling tower circulating water treatment system comprises a cooling tower, a heat exchanger, a water pump and a filter, wherein the cooling tower is connected with the heat exchanger; the heat exchanger is connected with the water pump; the water pump is connected with the filter; an electrochemical water treatment device, an ozone generating device and an electric adsorption desalting device are also arranged between the cooling tower and the filter; the ozone generating device and the electric adsorption desalting device are connected in parallel; a cold water tank is also arranged at the bottom of the cooling tower; the electrochemical water treatment device is arranged in the cold water tank; the ozone generating device and the electric adsorption desalting device are arranged in a bypass of a circulating water system pipeline; and the water tank is connected with the ozone generating device and the electric adsorption desalting device which are connected in parallel through a pipeline. Compared with the prior art, the novel cooling tower circulating water treatment system disclosed by the invention has the advantages that all the used technologies are based on electrochemistry, a medicament does not need to be additionally added or is rarely used, the aim of saving the medicament can be greatly achieved, and the environment-friendly effect is good; water in the water tank is circularly utilized, and the water saving performance is good; and the circulating water treatment cost is low.

Description

technical field [0001] The invention relates to the technical field of cooling tower circulating water treatment, in particular to a novel cooling tower circulating water treatment system. Background technique [0002] Circulating water for cooling towers is a major part of industrial water use. In petrochemical, electric power, steel, metallurgy and other industries, the amount of circulating cooling water accounts for 50-90% of the total water used by enterprises. Due to the different salinity in the raw water, when the circulating cooling water is concentrated to a certain multiple, a certain amount of concentrated water must be discharged and new water added to ensure that the circulating cooling water system does not scale or corrode. [0003] Due to the restriction of the concentration ratio of circulating cooling water, a certain amount of concentrated water must be discharged and a certain amount of new water must be replenished during operation. Keep the salt conte...
