Problems solved by technology

[0005] The invention puts the air purification system in the house in the exhaust channel, and uses the principle of heat transfer and inertial separation to design the air dehumidification, purification, temperature adjustment and exhaust system in the pig house in the cold area, which solves the problem that the air outlet of the pig house in the cold area cannot freeze in winter. For the problem of normal work, in winter, use the temperature difference between inside and outside the house and inertial force to condense and dry the discharged humid air, and then discharge the condensed water into the house for recycling and discharge; in summer, the air in the house can be directly discharged by the fan after purification, which has The structure is novel, scientific and reasonable, the gas dehumidification, purification, temperature adjustment and exhaust effect in the house are good, the degree of automation is high, the applicability is strong, the operation failure is small, and the characteristics of energy saving provide a technology for improving the conditions of pig houses in cold areas. support

Embodiment Construction

[0009] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. An air dehumidification, purification, temperature adjustment and exhaust system for pig houses in cold areas. A condensation inner pipe 21 and a condensation outer pipe 22 are installed on the outside of the wall 23 of the house. The condensation outer pipe 22 is fitted and installed on the outside of the condensation inner pipe 21. A front annular cavity 24 is provided between the inner surface of the condensing outer pipe 22 and the outer surface of the condensing inner pipe 21; The gas-liquid separation outer tube 20 is installed on the wall body 23 of the house, and the gas-liquid separation inner tube 19 is mated and installed in the gas-liquid separation outer tube 20 lumen. A rear annular cavity 25 is provided between the inner surface of the tube wall of the tube 20 and the outer surface of the tube wall of the gas-liquid separation inner tube 1...

Abstract

The invention relates to an air dehumidifying, purifying, temperature-adjusting exhausting system for a hog house in a cold region and belongs to a livestock raising facility. The system comprises a condensing system composed of an outdoor air inlet pipe, an outdoor air filter and condensing inner and outer pipes, a gas-liquid separating system composed of the condensing inner and outer pipes, anindoor gas and liquefied water discharge pipe, a liquefied water collector, an outdoor air discharge main pipe, an outdoor air discharge branch pipe, an outdoor air liquefied water discharge pipe andan indoor gas discharge pipe, an air cleaning system composed of an indoor gas purifier and an outdoor air filter and an automatic control system composed of a temperature sensor, a humidity sensor, atemperature controller, a humidity controller, a frequency converter, a heater and an indoor gas leading fan. The system solves the problem that an exhaust port of the hog house in the cold region inwinter cannot work normally and the indoor condition is poor, and has the characteristics of being novel, scientific and reasonable in structure, good in indoor dehumidifying, purifying and temperature-adjusting exhausting effect, high in degree of automation and high in applicability.

Description

technical field [0001] The invention belongs to animal husbandry facilities, and mainly relates to an air dehumidification, purification, temperature adjustment and air exhaust system for pig houses suitable for cold regions. Background technique [0002] In intensive pig production, due to the high stocking density, the space in the pig house is relatively closed and the air circulation is poor, which makes the air humidity in the house high and the content of harmful gases is high, which affects the health of the pig herd. Ventilation can introduce fresh air outside the house into the house to ensure sufficient oxygen in the house, remove heat, humidity, dust, ammonia, hydrogen sulfide and carbon dioxide and other harmful gases in the house, and improve the air quality in the house. Different seasons have different purposes for pig house ventilation. In hot and high temperature summer, ventilation can remove a large amount of waste heat in the house, reduce the high temper...
