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 the 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 produced that decomposes of the feed the like waste of the ight soil that the gas pollutant in 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 the gas such as ammonia, hydrogen sulphide is soluble in water for these odorants, therefore, can be adsorbed by positions such as people and animals' mucous membrane, conjunctivas, cause that hyperemia, oedema and even inflammation appear in conjunctiva and respiratory system mucous membrane, the caused body respiratory center of high concentration is benumbed and death; If animal in the environment in the low concentration foul smell, can weaken the constitution for a long time, productivity descends, and Abwehrkraft des Koepers reduces, and brings out multiple infectious disease, thereby has a strong impact on the economic benefit of cultivation.In addition, the gas pollutant emitted from hen house, as ammonia and greenhouse gases etc., can cause serious harm to atmospheric environment and the ecosystem.
The ight soil of chicken excretion is the major sources of gas pollutant in hen house, is the key factor that affects the hen house IAQ.In hen house, generally more approach the chicken manure surface, the concentration of polluting object is higher, very large to the chicken health hazard of living in ground.Reducing the effective and easy method of gaseous contamination substrate concentration in 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 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 that hen house is discharged is processed and purified is installed filter at exhaust outlet usually, but affected by weather etc., in the waste gas that ventilating system is discharged the gaseous contamination substrate concentration one day or whole production cycle Wave very large, the gravity-flow ventilation hen house generally adopted for China, still lack the method that can effectively control fast air quality in house simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of hen house IAQ control method and system, to solve the hen house chicken manure, produce high density pollution gas and can't discharge and endanger the technical problems such as chicken health, follow-up gas pollutant focus on.
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 outside hen house after frequency conversion fan, by magnetic valve, with Ozone removal equipment separately, with fresh air sources, be connected respectively; First by frequency conversion fan, bleed the dusty gas of chicken manure surface high concentration in hen house is extracted out, the port of export of frequency conversion fan is communicated with Ozone removal equipment through magnetic valve and disconnects with fresh air sources, makes the dusty gas of discharge be purified; Perhaps fresh air sources carries fresh air to enter the concentration that reduces dusty gas in hen house through another magnetic valve by frequency conversion fan, now magnetic valve and Ozone removal equipment disconnect, so circulation, dusty gas concentration in hen house is controlled in prescribed limit, avoids dusty gas excessive concentration harm chicken health.
The output of described frequency conversion fan, input and the time length that stops three kinds of duties is determined according to weather conditions, summer and autumn the fecal pollution gas emissions large, three kinds of duty times are identical, are 2 ~ 4 hours; Winter-spring season fecal pollution gas emissions is little, also needs insulation in 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 arranged on to the ight soil surface in hen house, on every polyethylene from high pressure process antipriming pipe, be equipped with equidistantly or the absorber of equidistant placement not, many polyethylene from high pressure process antipriming pipes are connected with an end of the outer frequency conversion fan of hen house through total gas piping, and the other end of frequency conversion fan is connected with fresh air sources with Ozone removal equipment separately by magnetic valve respectively.
The beneficial effect that the present invention has is:
1. be not subject 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, being beneficial to the improvement of chicken zone of action air quality, improving chicken health and wellbeing level.
3. with the She Nei ventilating system, compare, 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 on the impact of giving up interior thermal environment, in winter, also can move.
The present invention is mainly used in the control of force ventilation and gravity-flow ventilation hen house IAQ.
