Air circulation type liquid collecting pool heat taking method

Abstract

The invention is applicable to the technical field of air-water heat exchange, and provides an air circulation type liquid collecting tank heat removal method. The air circulation type liquid collecting tank heat removal method comprises the following specific steps that 1, a heat exchange packing bed is arranged, and a PVC (polyvinyl chloride) water drenching packing layer is arranged on a liquidcollecting tank; 2, the heat exchange packing bed is leached, in-situ leaching liquid is uniformly leached on the heat exchange packing bed by using a liquid distribution water pump, a water suctionport liquid supply pipe and a water distribution disc; 3, primary air-water heat exchange is conducted, specifically, a heat source tower serves as power, low-temperature air penetrates through the heat exchange packing bed, shallow geothermal heat is conducted to circulating air through packing, and then the circulating air enters an air pipe; 4, secondary air-water heat exchange is conducted, specifically, a booster fan serves as power, and circulating air fully absorbing heat in the air pipe is conveyed to the closed heat source tower; and 5, a primary medium water pump provides power, andheat in the primary medium water is conducted to secondary medium water through a heat exchange coil. Therefore, the purpose of saving resources is achieved by utilizing waste heat in in-situ leachinguranium mining engineering.

Description

technical field [0001] The invention relates to the technical field of air-water heat exchange, in particular to an air circulation type liquid collection tank heat extraction method. Background technique [0002] The most typical application of using air as a heat source carrier is a cooling tower (heat source tower), which releases heat into the air in summer and absorbs heat from the air in winter. Combined with a water source heat pump evaporator system, it can provide buildings with cooling and cooling throughout the year. heat source. This has a certain application case in my country's hot summer and cold winter areas. However, in the cold or severe cold areas in northern my country, due to the cold winter climate, it is impossible to extract the heat of the outdoor air through the cooling tower (heat source tower), and the heat pump evaporator system of the heat source tower is basically unusable. [0003] The in-situ leaching liquid is an important supporting facil...

AI Technical Summary

Problems solved by technology

[0004] However, in-situ leaching uranium mining projects in my country generally do not use in-situ leaching as a low-temperature heat source. There are four main reasons: first, the water quality of in-situ leaching is poor, and most calcium and magnesium ions exceed the standard; second, the temperature of in-situ leaching is low, generally between 10 and 20 ℃, or even lower; third, it is highly corrosive, and the ground immersion liquid oxygen, Cl - The concentration is high, especially the oxygen concentration exceeds the standard. This is a characteristic that other industries do not have, and it is also the main reason for the corrosion of heat exchange equipment. Yuan / m 3 This makes the operating cost of the ground water source heat pump evaporator project greatly increased, and most projects have poor economic benefits

[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
