Low-emission dehumidification system based on rainwater collecting module

Abstract

The invention relates to a low-emission dehumidification system based on a rainwater collecting module. By means of a principle that water vapor encounters cold to condense into water, a fan utilizesair in a greenhouse, the air enters an air flue through an air inlet pipe to be encountered with a condensing sheet of a cold water pipe to condense into water, air which is relatively small in humidity then returns to the greenhouse from an air outlet pipe, and condensed water flows into a water collecting hole from a cover plate of a water storage pond and returns to the water storage pond; thedevice can ensure reduction of water in the air on the condition that the temperature in the greenhouse is relatively small in change, and meanwhile, the water is saved, and the heat loss and consumption of manpower as a result of a conventional ventilating mode are avoided. Water in the cold water pipe is cold water in the bottom of the water storage pond. Water is circulated to the cold water pipe from the bottom of the water storage pond through the water outlet pipe by means of a water pump, and then returns to the water storage pond through a water return pipe. According to the siphoningaction, no high demand is put on power of the water pump, and the water temperature can be increased while the energy is saved. The growth and development of crops can be promoted. The problem that water volatilizes to affect the humidity in the water pond is avoided by means of the buried water storage pond.

Description

technical field [0001] The invention relates to a dehumidification device, in particular to a dehumidification device utilizing the water cycle condensation of an underground rainwater collection device. Background technique [0002] Taking the greenhouse with relatively high humidity as an example, the air humidity in the greenhouse has a significant impact on the transpiration, photosynthesis, disease occurrence and physiological disorders of greenhouse crops: [0003] 1. Air humidity affects transpiration, which is not only the driving force of water absorption, but also the driving force of mineral nutrient transport. High air humidity and weak transpiration will reduce the ability of plants to transport mineral nutrients. Transpiration can also adjust the temperature of the leaves. If the temperature is high, the air humidity is high, and the transpiration is weak, the leaves may be burned. The impact on transpiration will indirectly affect the alternation of dryness ...
