Water circulation recovery unit of wet curtain heat exchange type housing

Abstract

A water circulation recovery unit of a wet curtain heat exchange type colony house comprises a recovery groove arranged under a wet curtain, wherein the lower end of the recovery groove is communicated with a circulation pool, the circulation pool downwards extends relative to the ground surface to be arranged in a soil layer, a filter screen layer is arranged at the position of a lower port of the recovery groove, and the bottom of the circulation pool is communicated to a motor through a pipe. Water forming the wet curtain is collected through the recovery groove and flows into the circulation pool to perform temperature reduction, the motor directly draws water from the bottom of the circulation pool when the wet curtain is formed during water drawing, water in the circulation pool is constantly, vertically and alternatively supplemented under the drafting force of the motor and performs heat exchange with the soil layer, and a relative constant low-temperature state of the water forming the wet curtain is ensured.

Description

technical field [0001] The invention relates to the relevant technical field of heat exchange in pens in animal husbandry, in particular to a water circulation recovery unit of a wet curtain heat exchange type pen. Background technique [0002] In the process of animal husbandry, the design of breeding pens should fully consider the ventilation problem. Especially in the high temperature season in summer, scientific and reasonable ventilation design can effectively remove the heat in the house and reduce the temperature of the house. In the north, it is also necessary to consider the humidity problem in the enclosure, and it is necessary to always ensure that fresh and humid fresh air is introduced into the enclosure to remove harmful gases, dust and pathogenic microorganisms. [0003] Ventilation is divided into natural ventilation and mechanical ventilation. Natural ventilation does not require special equipment, power or energy, and is easy to manage. Therefore, in prac...

Problems solved by technology

However, the current wet curtain heat exchange pens have the problem of waste of water resources, that is, cold water forms a wet curtain and flows down from the upper end of the pen, and then directly enters the drainage pool to be discharged as waste water. Water recovery, such as for the cleaning of pens, but because of the large amount of water used for heat exchange in the wet curtain, it is difficult to achieve complete recovery, so in the latter case there is still a large waste, and this part of the water is recycled for such as cleaning The structure of some recycling facilities used in pens is relatively complicated, the amount of work is large, the construction cost of pens is high, and maintenance is difficult
