Zero-pressure condensed water recovery and reuse device for exhaust steam refrigerator

Abstract

The invention discloses an exhaust steam refrigerator zero-pressure condensate-recycling system, which comprises a first pipeline, a second pipeline, a third-stage water storage tank, a temperature controller and level controllers; the first pipeline is arranged between a cooling tower water tank and a cooling tower, and is provided with a water pump and a first control valve, and the second pipeline is arranged between the cooling tower water tank and the cooling tower; the third-stage water storage tank communicates with the cooling tower water tank through a third pipeline, and the third pipeline is provided with a second control valve; the temperature controller is used for controlling the opening or closing of the first control valve or the second control valve according to water temperature; and the level controllers are used for controlling the opening or closing of the water pump according to water level. The system substitutes for manpower to control the opening and closing of the water pump and the control valves, thus increasing the automation degree; and moreover, the temperature controller can control the temperature of condensate water, so that the temperature of recycled condensate can be within a needed range and can meet the requirement of rubber and tire production processes on the temperature of softened water.

Description

technical field [0001] The invention relates to the technical field of recovery and reuse of condensed water, in particular to a zero-pressure condensed water recovery and reuse device of a exhaust steam refrigerator. Background technique [0002] With the rapid development of rubber, tire, chemical, petroleum, textile, clothing and food industries, the demand for water vapor is also increasing. [0003] However, most of the condensed water generated after the use of water vapor in these industries is discharged, resulting in a waste of water resources; and most rubber and tire production processes require a large amount of demineralized water (water that removes calcium and magnesium ions) for For cooling water and superheated water, the preparation of softened water requires the purchase of softening water equipment, which requires a large investment in equipment, and in the process of preparing softened water, raw materials such as industrial salt and resin are needed, an...

AI Technical Summary

Problems solved by technology

[0005] The condensed water recovered from the cooling tower can be used as softened water, but it is difficult for this device to meet the requirement of softening water temperature of 30°C-35°C in rubber and tire production; and the device requires manual control, resulting in a low degree of automatic control

[0006] Therefore, how to solve the problem that the degree of automation is low and the temperature of the recovered condensed water does not meet the temperature required in the production process is a technical problem that those skilled in the art need to solve
