Description

An odorless and epidemic-proof pig house

technical field

The utility model relates to an odorless and epidemic-proof pig house, which is particularly suitable for use in the pig raising industry.

Background technique

In the pig industry, a good pig house environment can effectively reduce and prevent pig diseases, but the existing pig houses still have the following problems:

sewage problem. Sewage mainly comes from pig farms with blisters and a small amount of water to flush the feces. The clean water has a certain effect on the dilution, absorption and hydrolysis of the feces. This method will cause the total amount of feces to increase several times to dozens of times. the humidity of the enclosure environment. The sewage is discharged from the underground trenches into the external sewage collection tank, or is separated from wet and dry by a solid-liquid separator, and the sewage is directly decomposed or used for biogas, or the sewage is deposited and naturally oxidized into the storage tank to wait for the farm season to return to the field, and part of the sewage is raised. In order to reduce odor pollution, the pig farms cover and seal the sewage tank for anaerobic fermentation and decomposition. Although the farm is returned to the field after water distribution, the surrounding of the farm and the roads adjacent to the farmland are often foul smelling, and breeding sewage is often returned to the field. The problem of burning seedlings and burning roots still exists, and there are still problems of odor pollution and common fertilizer damage.

The main problems faced by aquaculture sewage are: liquid pollution source, large water volume, and fertilizer damage. Conventional technology solves the above problems, which requires a lot of land, large pool capacity, high investment in facilities and equipment, and complex engineering.

Odor problem. The odor in the house is the unique odor of the swine house odor formed by the odor of manure, the breathing exhaust gas of livestock and poultry, the smell of livestock and poultry, the smell of feed, and the odor of organic matter fermentation and humidity. The odorous exhaust gas reaches a certain concentration in the house. At present, odorous waste gas aerosol is formed, which constitutes the first pollution source of breeding waste in the farm. At present, the odorous waste gas of pig houses is controlled by a large amount of clean water to absorb and accommodate the odor of manure, and the second is by ventilation and ventilation. Window fans and wind hyacinths directly discharge the smelly waste gas out of the feeding house, and continuously inhale fresh air from the air inlet to dilute the aerosol in the house to improve the air quality of the feeding house; a few large enterprises adopt the black net method and biological filter/filter tower. The discharged odor is discharged after reprocessing.

There are several problems with traditional direct ventilation: 1. Ordinary window fans are mostly installed on the walls of the feeding house. When the odorous exhaust gas is pumped and discharged, the fecal odor will be drained under the slatted floor and continuously flow upward through the feeding house space before being discharged. , it is not good for the health of pigs and breeders, and it also artificially leads to an increase in the amount of odor replacement in the feeding house. 2. Due to the close distance between the farm and the community, each farm is a source of odor pollution, and the odorous waste gas emitted has an impact on the life and production of the nearby environment. The odor disturbance incident is an environmental protection incident with the highest proportion of rural pollution complaints; 3. For the density breeding area, due to the too small distance between the breeding farms, the odorous exhaust gas from each farm is directly discharged to form continuous non-point source environmental pollution, resulting in the saturation of the local breeding environment capacity. The odor of the feeding house is mainly fecal odor and fishy scum, and the odor of the sewage tank is mainly odor of manure, anaerobic decomposition of organic matter, methane and other odors. Burning roots and other fertilizer problems. 4. Public environment and health and safety issues. On the one hand, methane is a greenhouse gas, and it is also a flammable and explosive hazardous chemical. Organic waste gas such as sulfide and methane constitute the smog factor, and the direct emission of odorous waste gas is contrary to my country's national policy of atmospheric governance.

Pig house disinfection and epidemic prevention issues. At present, the disinfection and epidemic prevention of pig farms is mainly an epidemic prevention measure to block contact disease infection. It is divided into farm environment and house disinfection measures. Farm environment disinfection mainly includes isolation and epidemic prevention measures and drug epidemic prevention measures. Isolation measures include prohibiting unrelated people. Entry with vehicle crews, wearing protection, management of special area quotas, killing of vector organisms, and separation management of livestock and poultry houses with suspected epidemics, etc.; drug epidemic prevention includes disinfection of vehicle disinfection pools, disinfection of personnel entering and leaving the field, and spraying and disinfection of the environment in the farm area and other preventive measures. The disinfection of the feeding house mainly includes: ventilation, vaccination, control and disinfection of the house, fumigation of the empty house, spraying of the retained medicine with the birds, and oral administration of the medicine. Anti-epidemic methods such as fog, ultraviolet irradiation in the disinfection room, disinfection blanket and micro-mist disinfection. These disinfection and epidemic prevention techniques have a good epidemic prevention effect on preventing contact-transmitted diseases such as personnel and logistics, but for the elimination of pathogenic bacteria in dynamic fluid air, the disinfection and epidemic prevention effect of drug disinfection methods is very limited. Conventional methods And powerless.

When disinfection is not required, disconnect the disinfection switch DZ.

The core of this process is outlined below:

First of all, the main function of the deodorization and control unit is to reduce and control the total amount of odorous exhaust gas in the pig house. Biogenerators are used to decompose and deodorize the pig manure and urine sewage collected in the sink under the slatted floor of the pig house, which greatly reduces the amount of odor source and odor in the pig house, reduces the total amount of ventilation and ventilation in the pig house, and effectively eliminates and controls the pig farm. The amount of volatile odor produced by the subsequent sewage and feces, using the dominant flora of beneficial microorganisms, bio-inhibits harmful bacteria, pathogenic bacteria and viruses in sewage and feces, and reduces the incidence of pig infection. Second, downward ventilation and exhaust, to further reduce and control the adverse effects of waste odor on pigs. The method of taking the odorous waste gas collection pipe to extract the waste odor from the floor of the pig house solves the problem of increasing the odor of the pig house, increasing the total amount of ventilation, and increasing the risk of pig disease caused by the traditional manure odor flowing upward through the feeding house. . Third, the exhaust purification and disinfection unit is compatible with the residual exhaust gas containing fumigant (the pig farm does a fumigation and disinfection before each pig entry), normal exhaust gas purification and discharge, and exhaust gas disinfection and epidemic prevention. During the fumigation, disinfection and epidemic prevention of empty houses, some high-concentration drug waste gas remains in the empty pig house, which is discharged through the drug residue waste gas discharge port of the exhaust purification and disinfection device in Figure 5; The exhaust gas is discharged from the exhaust gas purification outlet; in the event of an epidemic, the exhaust gas after purification treatment needs to be sterilized and discharged from the exhaust gas disinfection outlet. Fourth, the main function of the ventilation and disinfection unit is to provide disinfection fresh air for the pig house and reduce the input of exogenous epidemics. As the fan continuously extracts the waste odor, a relatively low-pressure space will be formed in the pig house, and the air in the environment will enter the ventilation and disinfection units 1-4 through the ventilation window 9 (non-sterilization room type) (non-sterilization room type) Figure 4 The ventilation and disinfection device, after being irradiated and sterilized by UV lamps, flows into the pig house naturally, that is, the prevention of exogenous epidemics is imported through air.

Through the deodorization and control unit 1-2, the exhaust purification and disinfection unit 1-3 and the ventilation and disinfection unit 1-4, the odor control in the pig house and pig farm area can be realized, and the environmental emission and spread of pathogenic bacteria and viruses can be reduced. , By strengthening the ventilation and disinfection of pig houses, it can effectively improve the ability of pig farms to prevent and control endogenous and exogenous epidemics during the epidemic period, and improve the public health and epidemic prevention environment capacity of high-density breeding areas. The operation process is divided into two modes, the normal ventilation mode, only the ventilation and ventilation circuits of the exhaust purification and disinfection units 1-3 are required to work, that is, only normal ventilation is required, and the exhaust gas can be discharged after biological purification. In the epidemic disinfection mode, the exhaust purification and disinfection unit 1-3 and the ventilation and disinfection unit 1-4 need to work at the same time, that is, close the disinfection DZ switch, turn on the UV lamp disinfection for ventilation and exhaust disinfection, and maintain ventilation and exhaust. Disinfection synchronous linkage mode operation.

The biogenerator will continuously release microorganisms into the water body, decompose the feces in the water body and eliminate the odor of sewage. The process reduces the odor concentration and odor volume of the original manure by 70-90%. After the beneficial microorganisms form the dominant flora in the manure, the water body presents the microbial characteristics of the dominant flora, which is beneficial to the harmful microorganisms, pathogenic bacteria and The virus is gradually inactivated by biological inhibition, that is, the biological disinfection and epidemic prevention method, which is simple and easy to use. The principle is to make the inoculants evenly distributed, not to affect the discharge of feces, and to be easy to remove or replace. According to the structure of the feeding house and the water tank, the shape of the small microorganism generator can be a box type, a strip type or a floating type structure. According to the actual needs, the generator is divided into one-time type and continuous type.

(2) Operation of the ventilation and disinfection unit

The fresh air is sucked into the air intake and disinfection unit space formed by the compartments of the pig house from the ventilation windows at the top of the pig house. In this environment, UV lamps/lamp groups are evenly installed, and there is no blind spot lighting in this link to ensure a certain UV irradiation intensity; The total environmental capacity of the air intake disinfection unit must be greater than the continuous irradiation time that can be maintained for more than 5 seconds according to the exhaust speed. Calculated according to the exhaust speed, the environmental capacity of the ventilation and disinfection unit must meet the continuous air volume requirement for 5 seconds; The new air irradiated and sterilized by the lamp group is evenly dispersed through the air inlet of the partition and enters the breeding space under the partition or the pig house with the partition to provide ventilation and oxygen for the pig house.

The ventilation and disinfection unit is divided into three states: normal ventilation, preventive disinfection and epidemic elimination, that is, no UV lamp/lamp group irradiation for ventilation, UV lamp/lamp group low-intensity irradiation and high-intensity irradiation.

(3) Operation of exhaust sterilization unit

This unit is a power unit for ventilation and ventilation in a pig house, which is not only an integral part of the deodorization and control unit, but also a power source for the disinfection air of the air inlet disinfection unit. The fan of the exhaust disinfection unit operates intermittently to extract and deodorize the exhaust gas, and is jointly controlled with the circuit of the intake disinfection unit.

When the exhaust and disinfection unit is exhausted, the odorous waste gas in the pig house is transported to the odorous waste gas disinfection device through the fan through the exhaust port at one end of the water tank at the bottom of the feeding house and the connected odorous waste gas collection pipe, and the odorous waste gas is discharged down the pig house. , to avoid and reduce the aggravation of air pollution in the house and increase the risk of harmful bacteria and pig infection caused by upward exhaust; after the odorous exhaust gas enters the odorous exhaust gas disinfection device, it is discharged into the environment after biological filter material adsorption and decomposition and UV irradiation disinfection treatment; According to the different inventory of the barn and the surrounding environment, three exhaust modes are designed.
