Heat pump dehumidification device and method for underground hot spring area of abandoned mine

Abstract

The invention discloses a heat pump dehumidification device and method for an underground hot spring area of an abandoned mine. The device comprises a fresh air inlet, an air filter, a first-stage heat pump dehumidification unit, a main air feeder, a mine air supply duct and a working area which are sequentially connected through a fresh air conveying pipeline. A mine exhaust duct, an exhaust fanand an exhaust outlet which are sequentially connected through an exhaust pipeline in the follow-up process of the working area are further included. The working area comprises a plurality of groups of working units which are connected in parallel, and each group of working unit comprises a two-stage heat pump dehumidification unit, a hot spring area air feeder and an underground hot spring chamber which are connected in sequence. And energy recoverers are further arranged on the fresh air conveying pipeline between the air filter and the first-stage heat pump dehumidification unit and the exhaust pipeline between the exhaust fan and the exhaust outlet. The energy recoverers and the two-stage heat pump dehumidification units are mainly arranged, the defects in the prior art are overcome, and the popularization value is high.

Description

technical field [0001] The invention relates to a heat pump dehumidification device and method for an underground hot spring area of ​​an abandoned mine, belonging to the technical field of air conditioning. Background technique [0002] Under the background of the construction of "ecological civilization", the construction of green mines and the reduction of environmental pollution have achieved good economic, environmental and social benefits. In the process of implementing the transformation of the mining industry, it has become an innovation to combine the treatment of abandoned mines with the development of underground hot spring tourism. [0003] In the process of building hot springs underground in abandoned mines, a very important project is the design of the ventilation and dehumidification system. At present, there are two commonly used dehumidification schemes. One is to use the original mine ventilation system to ventilate and dehumidify. This system is only sui...

AI Technical Summary

Problems solved by technology

One is to use the original mine ventilation system to ventilate and dehumidify. This system is only suitable for the situation where the moisture content of the outdoor air is less than that of the underground hot spring area. It is generally suitable for winter operation, and the summer operation is restricted. If the water content is greater than the moisture content of the underground hot spring area, the humidity in the hot spring area cannot be removed, which does not meet the design requirements for the humidity of the hot spring area, and is not suitable for year-round operation.

Another type of dehumidification system is to add a dehumidification unit to the mine ventilation system. The dehumidification system can meet the humidity requirements of the underground hot spring area in summer and meet the operating conditions throughout the year. However, the air supply and exhaust are all DC systems, and the energy is not recovered. Utilization, the energy loss is huge, the operating cost increases, and it does not comply with the energy-saving policy
