Combined dehumidifier in subway station and dehumidification method and application thereof

Abstract

The invention provides a combined dehumidifier in a subway station and a dehumidification method and application of the combined dehumidifier. The dehumidifier comprises a mobile trolley, the mobile trolley is provided with a draught fan, the air feeding end of the draught fan is connected with a refrigerating and dehumidification system, an inlet of the refrigerating and dehumidification system is provided with an electrostatic dust collector, and the air sending end of the draught fan is connected with a temperature-raising and dehumidification system. Three dehumidification methods including refrigerating dehumidification, temperature-raising dehumidification and ventilating dehumidification are adopted simultaneously, the moisture content of the air in the subway station can be loweredrapidly, dehumidification efficiency is improved, safe operation and construction quality of all professional electrical equipment are guaranteed, and a safe and good construction environment is provided for workers. The combined dehumidifier in the subway station is used for dehumidification of a construction work area in the subway station, and when the combined dehumidifier is applied, a convection current is formed between the draught fan of the combined dehumidifier in the subway station and exhaust fans at wind gaps of the two ends of the subway station.

Description

Technical field [0001] The invention belongs to the field of dehumidification technology, and specifically relates to a combined dehumidification device in a subway station and a dehumidification method and application thereof, and is particularly suitable for dehumidification in a construction operation environment with a large moisture content in a subway station. Background technique [0002] A humid construction environment in subway stations has always been a serious problem. The main reason is that subway projects are generally underground. There are many professional cross-operations in the construction stage, the use of construction water is large, the air circulation is not smooth, and the source of moisture is extensive. During the construction phase, the composition of the wet load in the subway station is very complex, mainly including the leakage of the enclosure structure, the exchange of the air wet load at the entrance and exit, the outdoor fresh rheumatic load, an...

AI Technical Summary

Problems solved by technology

However, during the construction process, all majors are in the construction and installation stage, and the ventilation and air conditioning system has not been put into operation. During the construction stage, only simple ventilation methods can be used to allow the air in the station to circulate to achieve the purpose of dehumidification

However, when the outdoor weather conditions are "high temperature and high humidity" in summer, the simple ventilation and dehumidification method has no obvious effect on the leakage of the civil structure and the condensation on the wall surface of the station. The accumulated water on the ground is removed. This method has harsh working environment, high labor intensity, and low work efficiency. It cannot fundamentally solve the problem of humid environment in the subway station.
