Abstract
The invention discloses an indoor air quality control method and system for a henhouse. A plurality of high-pressure polyethylene perforated pipes are mounted on the surface of feces in the henhouse, absorbers which are arranged at equal intervals or unequal intervals are arranged on each high-pressure polyethylene perforated pipe, the plurality of high-pressure polyethylene perforated pipes are connected with one end of a frequency conversion fan outside the henhouse via a main gas pipeline, and the other end of the frequency conversion fan is respectively connected with an odor removing device and a fresh air source through electromagnetic valves. When in air extraction, high-concentration polluted gas in the henhouse can be directly extracted and transmitted to the outside of the henhouse; when in air supply, fresh air outside the henhouse can be conveyed into the henhouse for local air exchange. The method and the system can not be affected by a ventilation system in the henhouse, and the system has two functions of collecting the harmful gas and conveying the fresh air, and can not only improve the air quality of a living region for chicken in the henhouse, but also be conductive to follow-up centralized treatment outside the henhouse, thus the discharge of gas pollutants is reduced. The method and the system are applicable to the henhouses adopting mechanical ventilation and natural ventilation.
Description
Technical field
The present invention relates to air quality control method and system, especially relate to a kind of hen house IAQ control method and system.
Background technology
The corrupt foul gas that produces that decomposes of the feed the like waste of the ight soil that the gas pollutant in the hen house is mainly drained from chicken, use bedding and padding and waste.In foul odour, mainly comprise nitride (ammonia, methylamine), sulphide (hydrogen sulphide, methyl mercaptan), aliphatic compound (indoles, acrolein and scatol etc.), carbonic acid gas and methane gas etc.Especially gas such as ammonia, hydrogen sulphide is soluble in water for these odorants, therefore, can be caused that hyperemia, oedema and even inflammation appear in conjunctiva and respiratory system mucous membrane by the absorption of positions such as people and animals' mucous membrane, conjunctiva, the caused body respiratory center of high concentration is benumbed and death; If animal is in the environment of low concentration foul smell for a long time, can weaken the constitution, productivity descends, and Abwehrkraft des Koepers reduces, and brings out multiple infectious disease, thereby has a strong impact on the economic benefit of breed.In addition, gas pollutant such as ammonia and greenhouse gases etc. from hen house emits can cause serious harm to the atmospheric environment and the ecosystem.
The ight soil that chicken drains is the major sources of gas pollutant in the hen house, is the key factor that influences the hen house IAQ.In hen house, generally more near the chicken manure surface, the concentration of polluting object is high more, and is very big to the chicken health hazard of living in ground.Reducing the interior effective and easy method of gaseous contamination substrate concentration of hen house is to ventilate, ignored effective removing of pernicious gas but mechanical ventilation system both domestic and external is often only considered the adjusting of thermal environment in the house, therefore often energy consumption greatly but can't fast and effeciently be discharged dusty gas, input outdoor fresh air.The method that the waste gas of hen house discharge is handled and purified is installed filter at exhaust outlet usually, but influenced by weather etc., the gaseous contamination substrate concentration fluctuates very big one day or whole production in the waste gas that ventilating system is discharged in the cycle, the gravity-flow ventilation hen house that generally adopts for China still lacks the method that can effectively control air quality in the house fast simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of hen house IAQ control method and system, produce high density pollution gas and can't discharge and endanger technical problems such as chicken health, follow-up gas pollutant focus on to solve the hen house chicken manure.
The technical solution adopted for the present invention to solve the technical problems is:
One, a kind of hen house IAQ control method:
Output, input flue are installed in hen house, and flue is near the chicken manure surface, flue connect gas piping to hen house behind frequency conversion fan, be connected with fresh air sources with separately Ozone removal equipment by magnetic valve respectively; Bleed by frequency conversion fan earlier the dusty gas of chicken manure surface high concentration in the hen house is extracted out, the port of export of frequency conversion fan is communicated with Ozone removal equipment and disconnects with fresh air sources through magnetic valve, and the dusty gas of feasible discharge is purified; Perhaps fresh air sources carries fresh air to enter the concentration that reduces dusty gas in the hen house through another magnetic valve by frequency conversion fan, this moment, magnetic valve and Ozone removal equipment disconnected, so circulation, dusty gas concentration in the hen house is controlled in the prescribed limit, avoids dusty gas excessive concentration harm chicken health.
The output of described frequency conversion fan, import and the time length that stops three kinds of duties is determined according to weather conditions, summer and autumn the fecal pollution gas emissions big, three kinds of duty times are identical, are 2 ~ 4 hours; Winter-spring season fecal pollution gas emissions is little, also needs insulation in the house, exports identically with the duration of input service state, be 2 ~ 4 hours, and the time of the state that quits work is 4-6 hour.
Two, a kind of hen house IAQ control system:
Comprise many polyethylene from high pressure process antipriming pipes, frequency conversion fan and two magnetic valves; Many polyethylene from high pressure process antipriming pipes are installed in ight soil surface in the hen house, be equipped with equidistantly on the every polyethylene from high pressure process antipriming pipe or the absorber of equidistant placement not, many polyethylene from high pressure process antipriming pipes through total gas pipings and hen house outward an end of frequency conversion fan be connected, the other end of frequency conversion fan is connected with fresh air sources with separately Ozone removal equipment by magnetic valve respectively.
The beneficial effect that the present invention has is:
1. be not subjected to the coop ventilation systematic influence, be particularly useful for the gravity-flow ventilation hen house.
2. directly collect the gas pollutant of removing bedding and padding or surface, manure pit high concentration and carry out the part ventilation, be beneficial to the improvement of chicken zone of action air quality, improve chicken health and wellbeing level.
3. compare with the She Nei ventilating system, directly collect the gas pollutant of removing bedding and padding or surface, manure pit high concentration and carry out local ventilation and only need lower air-flow and pressure, save the energy, and more stable gaseous contamination substrate concentration can be provided, be beneficial to follow-up focusing on.Simultaneously, lower air-flow is less to the influence of thermal environment in giving up, and also can move in winter.
The present invention is mainly used in the control of force ventilation and gravity-flow ventilation hen house IAQ.
