Double-channel cold and heat source haze purifying and heating tower

Abstract

The invention discloses a double-channel cold and heat source haze purifying and heating tower. The double-channel cold and heat source haze purifying and heating tower is composed of a bottom air inlet liquid film evaporation and cold purification system, an upper air inlet finned tube haze absorption heating system and a minus-temperature heat storage finned tube frost and haze removing system. The double-channel cold and heat source haze purifying and heating tower is characterized in that an openable air port of a low heat source is closed in summer, dry hot circulating air enters the surface of a water-cooling liquid film heat exchange layer through a lower air inlet grid, so that a liquid film is formed and evaporated, the outlet water temperature is low, and the cooling efficiency of a refrigerator is improved; drifting moisture is removed through a low heat source fin type heat exchanger, and loading and atmospheric circulation are achieved through driving of a draught fan; in winter, the openable air port of the low heat source is opened, a haze wet cold heat source directly releases low-temperature heat energy through freezing of the low heat source fin type exchanger, so that frost and haze removal can be conducted twice in a day cycle under the minus-temperature climate condition by means of 2% of stored heat energy of the heat source, and the low-temperature heat source having the atmospheric environment purification function is obtained to serve as a heat source of a heat pump.

Description

technical field [0001] The dual-channel cold and heat source smog purification heat extraction tower of the present invention involves two major fields of new energy and energy saving technology, environmental protection and resources in my country. [0002] New energy, energy-saving and environmental protection technology, the technology combines the high-efficiency open horizontal cooling tower in summer and the high-performance fin coil heat exchanger heat source tower in winter, and retains their respective performance advantages through dual air ducts. In summer, the dry and wet spherical difference air generated by solar energy conversion can be used to independently enter the air grid, and the external water liquid film evaporative cooler can improve the cooling efficiency of the refrigerator; in winter, the horizontal finned coil can be used to absorb the smog and damp cold air as a heat pump. It can purify smog and haze air while extracting heat, and use independent a...

Problems solved by technology

[0008] Compared with the conventional open heat source tower, it can effectively solve the problem of absorbing low-temperature heat source in winter, external circulating solution liquid-gas exchange and mass melting process, resulting in solution moisture drift, polluting environment, corroding metals, and more serious pollution than boilers. The loss accounts for more than 20% of the heating operation cost in winter and drops to less than 2%, so that the built-in circulating solution is not diluted by the condensed water from heating, and the solution concentration is stable to ensure the safety of the heat pump unit
