Closed water circulation device

Abstract

The invention discloses a closed water circulation device which comprises a first industrial water tank, a second industrial water tank, and an industrial recycling water tank, wherein the first industrial water tank is separated from a processing water tank by a partition board; the second industrial water tank is connected with the first industrial water tank through a branch pipe of a main industrial water pipe; a water outlet is formed in the second industrial water tank; the water outlet is led to an inlet pipe of a first industrial water pump and a second industrial water pump through carbon steel pipes; the first industrial water pump and the second industrial water pump are connected with the second industrial water tank through the carbon steel pipes; the industrial recycling water tank is connected with a first industrial recycling water pump and a second industrial recycling water pump through stainless steel pipes; the first industrial recycling water pump and the second industrial recycling water pump are connected with the second industrial water tank and the processing water tank through the stainless steel pipes. The closed water circulation device has the beneficial effects that industrial water is converted into closed circulating water, and one industrial water tank is added, so that industrial water reserves are increased, meanwhile, industrial water forms closed circulation to prevent accidents from happening, and better economic benefit is brought about.

Description

technical field [0001] The invention relates to the technical field of circulation devices, in particular to a closed water circulation device. Background technique [0002] When the industrial water used for desulfurization of coal-fired generating units is open water, there will be safety hazards in the desulfurization equipment of the main plant after the industrial water is cut off, and the number of non-stop times will increase. Since the industrial water of the power plant uses river surface water, it is sent to the thermal power plant through the water pump through the raw water pipeline after precipitation to be used as chemical desalinated water, fire water, turbine open and close water, auxiliary cooling water, desulfurization industrial water, etc. The existing water treatment device will have industrial water interruption accidents, and because the current industrial water tank is only 50m 3 About, under full load, it is only enough for desulfurization equipment...

AI Technical Summary

Problems solved by technology

The existing water treatment device will have industrial water interruption accidents, and because the current industrial water tank is only 50m 3 About, under full load, it is only enough for desulfurization equipment cooling water and mechanical sealing water for 1 hour. The industrial water interruption event caused the liquid level of the desulfurization industrial water tank to drop below the inlet of the industrial water pump, which brought great safety hazards to the operation of the desulfurization equipment.

[0003] When the industrial water is open water, because the desulfurization industrial water is mainly used as auxiliary cooling water and mechanical sealing water, and finally enters the absorption tower as the make-up water of the absorption tower, and is not recycled, so the industrial water consumption is large, and every 4.68 yuan per ton, the production cost of the project department increased, unable to meet the requirements of energy saving and economic operation
