Winter sunlight greenhouse dehumidification tower

Abstract

The invention relates to a winter sunlight greenhouse dehumidification tower, and belongs to the technical field of agricultural engineering equipment. The tower is composed of a body shell, a draught fan, a loading and unloading door, an air inlet door, an air outlet, a moisture absorbent, a fixing plate, partition plates, a tower bottom plate and a filter net. The moisture absorbent is quick lime, is packaged by a non-woven bag and then is put on the partition plates, three layers of partition plates are arranged and are of a stainless steel net structure, an electric control door is adopted as the air inlet door, and is opened and closed along with starting and stopping of the draught fan, the draught fan is fixed to the air outlet through the fixing plate, and starting and stopping of the draught fan are controlled by a humidity controller; the filter net is arranged above the fixing plate and is an efficient filter filter net. The dehumidification tower is suitable for humidity regulation of a winter sunlight greenhouse and has the beneficial effects of being high in dehumidification speed, large in dehumidification amount, low in dehumidification cost, high in automation degree, free of reducing the temperature of the greenhouse in the dehumidification process and the like.

Description

[0001] 1. Technical field [0002] The invention relates to a winter solar greenhouse dehumidification tower, which belongs to the technical field of agricultural engineering equipment. [0003] 2. Background technology [0004] In winter, the solar greenhouse is very closed for the purpose of heat preservation, the indoor moisture is not easy to dissipate, and the air humidity is very high. Especially in the case of continuous cloudy days, the humidity of the air in the greenhouse remains high for a long time. The high humidity environment is not only unfavorable to the growth and production of plants, but also easily causes physiological disorders of crops, restricts plant transpiration, affects the absorption and utilization of soil nutrients by roots, and aggravates the occurrence and spread of plant diseases. Therefore, the high humidity environment in the solar greenhouse has become one of the main factors affecting the yield of vegetables, and it is of great significanc...

AI Technical Summary

Problems solved by technology

But if it is cloudy, because the air outside the greenhouse is cold, natural ventilation cannot be carried out, and the high humidity in the greenhouse will remain for a long time, which is not good for plant growth.

If the measures of forced exhaust are adopted, it will inevitably bring about the problem of lowering the temperature in the greenhouse
