Constant pressure condensation water recycling device

Abstract

The invention provides a constant pressure condensation water recycling device. The constant pressure condensation water recycling device comprises a recycling tank, wherein the upper part of the side wall of the recycling tank communicates with a water inlet pipe; a sprayer is arranged at the inner bottom of the recycling tank; the sprayer is arranged at the communicating opening of the recycling tank and the water inlet pipe; a constant pressure exhaust pipe extends out of the top of the recycling tank; an exhaust valve is arranged at the top end of the constant pressure exhaust pipe in a covering and pressing manner; the bottom of the recycling tank communicates with a drain pipe; a plurality of stopping tooth groups and a stopping block are arranged in the constant pressure exhaust pipe; and the stopping block is close to the outlet end of the constant pressure exhaust pipe. According to the constant pressure condensation water recycling device provided by the invention, the air exhaust quantity of the exhaust valve can be adjusted according to the air pressure in the recycling tank, and the recycling tank body is prevented from vibrating.

Description

technical field [0001] The invention belongs to the technical field of industrial water recovery, in particular to a condensed water recovery device for gas-water separation. Background technique [0002] During the recovery of waste water and waste steam in the boiler system, the high-temperature condensate also contains steam and other impurities. The steam increases the pressure of the condensate recovery pipeline, generates back pressure on the trap, and causes the condensate to be transported poorly, and the trap produces condensate retention. Cause a large amount of steam exists in the condensate collection pipe, and the pressure rises. [0003] The commonly used condensate recovery tank can only recover a small part of waste steam, most of the steam is discharged when the pressure of the recovery tank is too high, and the discharge process is unstable. When the gas consumption peaks, the exhaust gas discharge pressure is too large, and the exhaust valve is frequently ...

AI Technical Summary

Problems solved by technology

[0002] In the recovery process of waste water and waste steam in the boiler system, the high-temperature condensed water also contains other impurities such as steam. The steam increases the pressure of the condensed water recovery pipeline, and the steam trap generates back pressure. The condensed water is not transported smoothly. A large amount of steam exists in the condensate collection pipe, and the pressure rises

[0003] The commonly used condensate recovery tank can only recover a small part of the waste steam, most of the steam is discharged when the pressure of the recovery tank is too high, and the discharge process is unstable. During the peak gas consumption, the exhaust gas discharge pressure is too high and the exhaust valve is frequent. Exhaust makes the tank vibrate, and a large amount of steam leaks out, causing energy waste and environmental pollution
