Device used for making irrigation water in condensing mode inside temperature-controlled greenhouse

Abstract

The invention discloses a device used for making irrigation water in a condensing mode inside a temperature-controlled greenhouse. The device used for making irrigation water in the condensing mode inside the temperature-controlled greenhouse comprises a temperature-controlled greenhouse. An air outlet and an air inlet are formed in the wall of the temperature-controlled greenhouse. An air condensation pipe device connected with the air outlet and the air inlet is arranged outside the temperature-controlled greenhouse. An exhaust fan is installed on the air outlet formed in the inner wall of the temperature-controlled greenhouse. A water collection device is arranged on a condensate water outlet of the air condensation pipe device. According to the device used for making irrigation water in the condensing mode inside the temperature-controlled greenhouse, moisture inside the temperature-controlled greenhouse can be condensed and recycled by using of the temperature variation between the temperature of the air inside the temperature-controlled greenhouse and the temperature of external environment. The irrigation water resource inside the temperature-controlled greenhouse is enabled to be recycled to an extent. The temperature and the humidity of the air inside the temperature-controlled greenhouse can be controlled. Therefore the device used for making irrigation water in the condensing mode inside the temperature-controlled greenhouse is beneficial for crop growth. The device used for making irrigation water in the condensing mode inside the temperature-controlled greenhouse has the advantages of being reasonable in structure, reliable in performance, low in manufacturing cost, small in energy consumption, and capable of reducing the production cost of farm produce of the temperature-controlled greenhouse.

[0002] As a modern agricultural facility, greenhouses are increasingly appearing in people's lives, especially the development of greenhouse vegetables and greenhouse melons and fruits, which has greatly enriched people's lives and played a role in improving and improving people's lives. The effect is becoming more and more important, and there are more and more varieties of planting in greenhouses. Greenhouse seedlings, peppers, greenhouse tomatoes, grapes, strawberries, greenhouse watermelons, etc., involve almost all vegetables and melon and fruit varieties. The growth of greenhouses Large-scale development has become a development trend of modern agriculture. Greenhouse vegetables in Turpan, Xinjiang first started in 2002. Because it is adjacent to Urumqi City, vegetable sales have a certain consumer market, coupled with the inherent advantages of sufficient sunshine in the area, short Within a few years, the number of vegetable greenhouses in Turpan has grown to more than 40,000, and it has gradually become the source of vegetable supply for Urumqi and surrounding cities. The temperature, humidity and light conditions in the greenhouse are directly related to the growth and development of crops. Reasonably adjust the temperature, humidity and light conditions in the greenhouse to form a small environment in the greenhouse that is conducive to the growth and development of vegetables. , high-quality, high-efficiency important link, greenhouse temperature and humidity control is extremely critical, the existing humidity control method is mainly through indoor and outdoor ventilation to reduce humidity, a little carelessness may cause the humidity in the greenhouse to be high, As a result, the slow growth of crops is caused, and the spread of diseases and insect pests is induced, which is not conducive to the growth and development of vegetables. The contradictory relationship is very unfavorable for the growth and development of crops in the shed. Water resources in arid areas are very precious. Water is the most fundamental constraint factor for the development of agriculture. The water needed by the crops in the greenhouse is completely guaranteed by artificial irrigation measures. Therefore , water saving has generally been paid attention to by people, and more advanced sprinkler irrigation and drip irrigation have been gradually adopted for irrigation, and some greenhouses have also adopted more advanced irrigation methods. However, the existing efficient water-saving irrigation methods can only reduce very limited seepage Leakage loss, the evaporation in the field of the greenhouse and the transpiration of the crops still need
