The following is the farm test data and test report:
note: s, showing that the air inlet of the monitor is along the airflow direction N of the strong wind, and showing that the air inlet of the monitor is opposite to the airflow of the strong wind machine
Direction (return air). The total length of the shed is 30 meters, 6 beams are arranged, 5 spaces are formed, each space is 6 meters, and 5 multiplied by 6=30 meters; setting 6 detection points in total, and detecting each point twice;
description of the effects: three possible down times are: 52 minutes; 63 minutes; 81 minutes; this test was carried out for a total time of 52 minutes, with 47 minutes ozone being maximal.
The details are as follows:
as shown in figure 1, the combination of ozone generator 1 and ozone diffuser 2 is hung at a specific position and height in the greenhouse, the computer controller 3 is installed at a position near the combination where people can conveniently operate, and the controller 3 can artificially set the length, width and height of the specification parameters of the farm and select the concentration: the temperature and humidity of the surrounding air source are sensed by the temperature and humidity sensors during the brooding period and the fattening period, on the other hand, the computer controller 3 controls the working time of the ozone generation and diffusion fan according to the set parameters and the automatically acquired temperature and humidity data to keep the ozone generation and diffusion fan in a required interval, the concentration of the interval is low, the range is narrow, the lower limit of the interval can effectively kill pathogenic microorganisms in a shed, and the upper limit cannot have adverse effects on newly-born pigs and pregnant sows. The ozone generator 1 is connected with the ozone diffuser 2 through 4 connecting supports with the length of 22 cm, the ozone diffuser 2 is connected with a cylinder with the length of 32 cm through an outer rotor fan with the diameter of 31.5 cm, the diameter of an outer opening of the cylinder is 10% smaller than that of an inner opening, the purpose is to improve the wind speed of the ozone diffuser (the diffusion fan), and 4 rectifying plates are arranged in the cylinder, and the purpose is to send airflow to the farthest end of the greenhouse. The air quantity of the fan enables airflow to form an airflow ring vertically in the shed along the longitudinal direction of a farm, and the airflow ring is called as follows: the air flow organization method is characterized in that 6 ozone generating sheets with the volume of 3.5g/h are matched with the air volume of the fan, so that the configuration is not arbitrary and is determined through long-term test verification, and the concentration of generated ozone is diffused and uniformly distributed in a greenhouse as soon as possible.
The working principle of the invention is as follows:
healthy cultivation in a cultivation environment has three problems, namely, amine gas (odor) generated by excrement, pathogenic bacteria naturally generated in the environment, flies attracted by food and odor, ozone is a strong oxidant and a broad-spectrum bactericide, the amine gas (odor) R3N + O3 → R3N-O + O2 is decomposed by using the strong oxidizing property of the ozone, the pathogenic bacteria in the environment are killed by using the broad-spectrum bactericidal property, and the flies are driven by using the special odor of the ozone, so that the purpose is achieved.
The ozone used in the planting industry and the breeding industry has a certain amount of problem, but the common ozone generator does not relate to the 'ozone amount', the corresponding sterilization effect cannot be achieved when the concentration is low, and the harmful effect on the bred livestock and poultry is caused when the concentration is high. According to the standards of the world health organization, the international ozone society and the ministry of health of China, the concentration which can be accepted by people is 0.1ppm, the contact time can be 8 hours, and the weight of poultry and nursery pigs in a farm is far less than that of human beings, so the concentration of the poultry and nursery pigs is required to be accurately controlled. Although the ozone generator is simple, no practical ozone generating equipment for air purification, deodorization, sterilization and fly repelling in a farm is available up to now.
The purification and disinfection application of ozone in the farm still involves the problems of rapid diffusion, uniform distribution and accurate quantification. The technology of the invention is that the high-concentration ozone flowing out from the outlet of the ozone generator is quickly diffused, evenly distributed and accurately quantified, so that the concentration of the ozone is always maintained in a set concentration range, namely, the lower limit can effectively kill pathogenic microorganisms, and the upper limit can not cause adverse effect on cultured animals, thereby theoretically ensuring the possibility of replacing a bactericide by the ozone and technically ensuring the reliability of replacing the bactericide by the ozone. Therefore, whether ozone can be used in the farm or not is not the existence or nonexistence of ozone, but the quantity and the degree of the ozone, the quantity is the total quantity of the ozone, the degree is the concentration of the ozone, and the concentration is the only index for measuring the sterilization effect of the ozone.
The source of the odor (amine) of the breeding farm is excrement, the odor which can be smelled by people, pigs and animals is actually caused by the excrement flowing through the air, the ozone is removed to be the odor (R3N + O3 → R3N _ O + O2) in the air, the odor is important, people see that the eyes of ducks in the duck farm are fumigated by the amine gas except for generating aversion to people and animals, the key is to influence the combination (oxygenation) of red blood cells and oxygen, the combination of the oxygen breathed by the animals and the red blood cells can improve the blood oxygen saturation, the combination of the amine gas and the red blood cells occupies the position of the oxygen, so that the local hypoxia in the organisms is cell-level asphyxia, and the odor of the excrement can escape into the air again after the shutdown of the control software through tests, so that the control software can be restarted after the shutdown for 2 hours, the odor cannot be smelled in the breeding environment all the time, and the environment is environment-friendly and healthy.
The invention relates to a practical livestock and poultry breeding, sterilizing and epidemic preventing machine. Because the space of the cultivation shed is extremely large, if the concentration distribution of ozone is not uniform, high local concentration exceeds the upper limit of the interval to affect the cultivated animals, and low local concentration is lower than the lower limit of the interval, pathogenic bacteria can not be killed, so that the corresponding using effect can not be achieved.
Fast diffusion: according to the principle of hydromechanics, the space of the cultivation shed is divided into two parts along the longitudinal upper part and the longitudinal lower part, the upper part is a high-concentration diffusion channel, the combination of an ozone generator 1 and an ozone diffuser 2 is hung at a specific position of the upper part and is as high as possible, the high-concentration ozone is diffused rapidly under the action of large air flow, the air flow reaches the other end of the shed all the time, the air flow returns back downwards under the combined action of gravity and resistance to reach the air inlet end of the combination of the ozone generator 1 and the ozone diffuser 2, an air flow ring is formed above and below the air flow, the air flow completes one circulation, the process is forcibly realized through the large air flow of a fan, and the rapid diffusion is realized by ensuring that the high-concentration ozone is not contacted with livestock and poultry, so that the adverse effect on the cultivated animals is prevented.
Uniform distribution: after one circulation, the air flow in the shed is continuously circulated under the continuous action of a large fan, the ozone concentration is diluted and uniformly distributed after a plurality of circulations, the ozone concentration in contact with the cultured animals is called as safe concentration, the ozone concentration gradually rises along with the time, and the process of rapid diffusion and uniform distribution is called as an air flow organization method.
And (3) accurate quantification: under the continuous circulation action of the air flow, the concentration of ozone at the lower part in the shed continuously rises, when the farthest point of the air flow circulation reaches the designed concentration, namely the set concentration interval is limited at the upper limit, the computer system can automatically turn off the ozone generator, so that the concentration of ozone in the shed does not rise any more (detection data such as an attached table, a detector of the concentration value is not in the system and is an additionally arranged high-precision detector, the timing of the computer is a mathematical model which is repeatedly verified, modified and approximated for a plurality of years), at the moment, the large fan still needs to work for a period of time continuously, ozone which is just generated is further diffused uniformly, the burning is prevented, when the delay time of the large fan is up, the large fan is turned off again, and epidemic prevention operation is completed.
The ozone purifying and sterilizing machine for the air of the livestock and poultry farm needs to be additionally matched with control software for use. The control software is a mathematical model and repeatedly verified and modified for several years, and each time the control software solves the equation of quaternion and quaternion twice: 1. the length, width and height of the greenhouse space are increased; 2. the temperature at that time; 3. the prevailing humidity; 4. different amounts of amine gas are generated in the brooding period and the fattening period; the four factors directly influence the ozone generation amount and further influence the ozone concentration, but the invention is interested in the ozone concentration, because the concentration is the only index for judging the ozone sterilization effect, and the controller respectively controls the working time of the ozone generator and the diffusion large fan, and the four elements, the generation amount and the ozone concentration are finally summarized into two different working times.
Theoretically, ozone can kill any microorganism, but has different concentration thresholds for killing different pathogenic microorganisms, and the killing effect is finished instantly once the required threshold is reached. The ozone generator has the characteristic that the generation amount of the same ozone generator is inversely proportional to the temperature and the humidity of an air source. The lower the humidity is, the larger the generation amount is, and when the relative humidity is less than 45%, the ozone has almost no sterilization effect, if the sterilization can not be performed and the animal feeding is easily influenced, therefore, the relative humidity is less than or equal to 35% and is set as a protection area, a control program below the humidity does not allow starting up, the sterilization is a problem in a farm, the oxidation deodorization is another big problem, and the consumed ozone amount is more, so that the farm uses 6 ozone generation pieces, and 2 pieces of ozone is more used than a planting shed.
The ozone sterilization is characterized in that: the larger the relative humidity of the environment is, the better the killing effect is, and it can be known that the larger the relative humidity is, the smaller the ozone generation amount is, so the starting time of the ozone generator must be prolonged, in order to enable the ozone concentration to be always in the set concentration range, according to the verification of long-term tests, the relative humidity is divided into three uneven sections from 51-99% relative temperature, and three coefficients are respectively selected: k1=96, K2=120, and K3=156, the brooding age is K4=0.65, the volume of the greenhouse length × width × height is V = m for harvesting, and the air volume of the big fan is Q = m for harvesting;
three working hours are specified in the fattening period, and two working hours are specified in the brooding period:
the ozone generator has three different working times in the fattening period:
1. operating time of ozone generator (min): min1= VK1/Q
2. Operating time of ozone generator (min): min2= VK2/Q
3. Operating time of ozone generator (min): min3= VK3/Q
The brood-time ozone generator has two different working times:
1. operating time of ozone generator (min): min1= VK1K4/Q
2. Operating time of ozone generator (min): min2= VK2K4/Q
The five working times are the total working time of the ozone generator after the length, the width and the height are determined and after different temperatures, humidities, young period selection and fattening period, and the shutdown time of the large draught fan is delayed for 5 minutes according to the shutdown of the ozone generator. The five working hours are different for each user's greenhouse space, so the five hours are determined by calculation according to the set volume parameters when the equipment is installed. A large number of experiments show that the temperature has small influence factor on the depth of ozone, so that the ozone generating device can be subjected to micro-adjustment during specific implementation and can also be set at the normal room temperature of 25 ℃.
The five working times refer to the working time of each time, the controller automatically turns off the ozone generator and the large fan after each deodorization and epidemic prevention is finished, but the controller automatically turns on the machine to work again after the machine is stopped for 120 minutes, and the operation is repeated in a circulating way, namely, the machine can automatically start, stop, start and stop 82308230, 8230and once the machine is started.
The relation between the five working times and the ozone concentration is similar to the result of a wind tunnel test of an aircraft, and is the result verified by numerous tests, and although the time lengths are different, the ozone concentration is always ensured to fall within the range required by people.
The parts not involved in the present invention are the same as or can be implemented using the prior art.
