Abstract

The invention provides a waste heat utilization system of well air. The system comprises a return air inlet path, a return air exhaust path, a fresh air inlet path, a fresh air exhaust path, a heat exchanger, axial-flow fans and valves, wherein the return air inlet path and the fresh air exhaust path are connected to one end of a first air flue and one end of a third air flue, and joints are equipped with valves; the other end of the first air flue and the other end of the third air flue are connected to the heat exchanger; the return air inlet path, the return air exhaust path and the fresh air inlet path are connected to one end of a second air flue and one end of a fourth air flue, and joints are equipped with valves; the other end of the second air flue and the other end of the fourthair flue are connected to the heat exchanger; and the axial-flow fans are arranged in the first air flue and the third air flue and / or the second air flue and the fourth air flue. The system recycleswaste heat in underground return air in winter to preheat air flues for fresh air circulation. In summer, return air is used as a cold source through valve conversion, so that the effects of cooling the air flues for fresh air circulation and reducing heat damages are reduced.

Description

technical field [0001] The invention relates to the technical field of energy saving, in particular to a well wind waste heat utilization system of an underground well. Background technique [0002] The heat pipe heat exchange system for well wind is specially developed for recovering the low-temperature waste heat of underground return air. Heating methods such as power consumption reduce operating costs and achieve energy saving and emission reduction. The system can replace the low-temperature residual heat of the downhole return air above 10°C, ensuring that the inlet air temperature at the wellhead is 2°C to 4°C in winter, meeting the antifreeze requirements of the wellhead. [0003] The existing underground return air heat pipe heat exchange system is provided with a fresh air inlet channel, a return air inlet channel, a fresh air outlet channel, a return air outlet channel, a heat pipe heat exchanger and an explosion-proof axial flow fan. [0004] In the winter heat...
