Performance detection testing system of mine air returning heat exchanger and using method thereof

Abstract

The invention relates to a performance detection testing system of a mine air returning heat exchanger and a using method thereof. The performance detection testing system comprises a cold and hot source device, an air pretreatment device, an air returning heat exchanger testing device and a measurement control device. The cold and hot source device provides cold and hot sources for pretreatment of air in the air pretreatment device and treatment of spray water in the air returning heat exchanger testing device, the air pretreatment device adjusts inlet air to be in needed mine air returning parameters through treatment such as heating, cooling, humidification and dust adding, the air returning heat exchanger testing device detects heat exchange capability, drag characteristics and dedusting capability of the mine air returning heat exchanger under simulation of actual operational states, and the measurement control device comprises a plurality of temperature and humidity sensors, pressure sensors, flow sensors and testers of dust contained concentration to measure parameters such as temperature, pressure, flow and dust content. The performance detection testing system can be widely used for performance detection and testing on the mine air returning heat exchanger.

Description

technical field [0001] The invention relates to a product performance detection test system and its use method, in particular to a mine return air heat exchanger performance detection test system and its use method. Background technique [0002] For most coal mines, mine return air has the advantages of large air volume and constant temperature and humidity throughout the year. Therefore, mine return air is a very high-quality source of heat or cooling. Through the joint use of the mine return air heat exchanger and the heat pump system, heat can be extracted from the mine return air in winter, and heat can be discharged to the mine return air in summer, thereby providing the required heat or cooling for coal mine life and production , so it can replace coal-fired boilers and central air conditioners, and has the effect of energy saving and emission reduction. [0003] Generally speaking, the performance indicators of heat exchangers mainly include heat transfer capacity an...

Problems solved by technology

For the special heat or cooling source of the mine return air, if the mine return air heat exchanger has performance indicators that cannot meet the requirements, it will directly affect the normal operation of the heat pump system that is expected to be connected, resulting in failure to meet the user's heat requirements. load demand

From the above analysis, it can be seen that it is very necessary to design a test system that can detect the performance parameters of the mine return air heat exchanger. However, there are no technical standards and methods related to the performance test of the mine return air heat recovery equipment at home and abroad. and patented technology
