Description
技术领域technical field
本实用新型属于一种气体收集设备,尤其涉及一种用于养殖舍的氨气净化和收集装置。The utility model belongs to a gas collection device, in particular to an ammonia gas purification and collection device for breeding houses.
背景技术Background technique
随着我国畜牧业的迅速发展,畜牧场规模化、集约化和机械化程度逐渐提高,畜牧村、规模养殖舍却常常出现环境纠纷。畜禽养殖场的空气污染主要来自于养殖场内散发的有味气体,畜禽粪便和污水发酵后会产生大量的氨气等有害气体,导致养殖舍内单位面积内氨气排放量升高,氨气不但容易导致动物应激,大大影响畜禽的生长速度和料肉比,而且严重污染了环境,是滋生蚊蝇、细菌繁殖和传播疾病的传染源,危害畜禽健康,影响人类正常的生产和生活。尤其是在气候寒冷的冬春季节,为了提高畜禽养殖舍的保温效果,绝大多数养殖户都将门窗关闭以减少通风量,畜禽养殖舍内的氨气含量会更高,严重影响了畜禽的正常生长,造成了养殖户的经济损失,而一旦随意排气通风,会使舍内气温变化过大,容易引发畜禽感冒,同时也造成了加热保温能源的浪费。With the rapid development of animal husbandry in my country, the scale, intensification and mechanization of livestock farms are gradually increasing, but environmental disputes often occur in animal husbandry villages and large-scale breeding houses. The air pollution in livestock and poultry farms mainly comes from the odorous gases emitted in the farms. After the fermentation of livestock and poultry manure and sewage, a large amount of harmful gases such as ammonia will be produced, resulting in an increase in ammonia emissions per unit area in the breeding house. Ammonia gas not only easily causes animal stress, greatly affects the growth rate and feed-to-meat ratio of livestock and poultry, but also seriously pollutes the environment. production and life. Especially in winter and spring when the climate is cold, in order to improve the thermal insulation effect of livestock and poultry breeding houses, most farmers close the doors and windows to reduce ventilation. The ammonia content in livestock and poultry breeding houses will be higher, which seriously affects the The normal growth of livestock and poultry has caused the economic loss of the farmers, and once the ventilation is done randomly, the temperature in the house will change too much, which will easily cause the livestock and poultry to catch a cold, and also cause a waste of heating and heat preservation energy.
畜禽养殖舍空气中的氨气主要来自畜禽肠胃消化、粪尿、饲料残渣和垫草等有机物腐败、细菌分解机体废物产生,是一种无色、有毒、具有强烈刺激性臭味的气体,可感觉最低浓度为5.3ppm,在垫料潮湿、酸碱度适宜、温度高、粪便多的情况下,氨气产生更快。畜禽舍中氨气的含量取决于饲养密度、通风情况、地面结构、饲养管理水平、粪污清除等。氨气的水溶液呈碱性,对黏膜有刺激性,严重时可发生碱灼伤,可引起眼睛流泪、灼痛、角膜和结膜发炎、视觉障碍。氨气进入呼吸道可引起咳嗽、气管炎、支气管炎、肺水肿出血、呼吸困难、窒息等。氨气具有还原性,其分子中的氢原子可被金属逐一置换,生成金属氨基化合物或氮化物,因此,氨气由肺泡进入血液,可与血红蛋白结合,使血红素变为正铁血红素,降低血红蛋白的携氧能力、血液碱储和血红素的氧化性能,从而出现贫血和组织缺氧。氨气是公认的应激源,是畜禽舍内最有害的气体,氨气可诱导家禽、猪等动物多种呼吸道疾病的发生,可诱导或提高肉鸡腹水症的发病率,在10-15mg/kg氨浓度下,会降低动物对感染的抵抗力。据测定,当鸡舍内氨气的浓度达到20mg/L时,各类常见病、多发病的发病率会骤然提高,当浓度升至50mg/L时,可使鸡的呼吸频率减慢,蛋鸡的产蛋量会因此而减少,雏鸡增重和饲料利用率大幅下降。一个56万只规模的养禽场,每小时能够排出10.5kg的氨气,一个年产8万头猪的养猪场,每小时向大气排放氨气达到130kg以上,而过多氨气排放不仅造成了大量饲料资源浪费,而且增加了环境压力。Ammonia in the air of livestock and poultry breeding houses mainly comes from the digestion of livestock and poultry intestines and stomachs, the corruption of organic matter such as feces and urine, feed residues and bedding, and the decomposition of body waste by bacteria. It is a colorless, toxic, and strong pungent odor gas. , the lowest concentration that can be felt is 5.3ppm, and ammonia gas is produced faster when the litter is wet, the pH is suitable, the temperature is high, and there is a lot of feces. The content of ammonia in livestock and poultry houses depends on the stocking density, ventilation, ground structure, feeding management level, and manure removal. The aqueous solution of ammonia gas is alkaline and irritating to mucous membranes. In severe cases, alkali burns can occur, which can cause tearing, burning pain, inflammation of the cornea and conjunctiva, and visual impairment. Ammonia entering the respiratory tract can cause cough, tracheitis, bronchitis, pulmonary edema and hemorrhage, dyspnea, and suffocation. Ammonia has reducing properties, and the hydrogen atoms in its molecules can be replaced by metals one by one to form metal amides or nitrides. Therefore, ammonia enters the blood from the alveoli and can combine with hemoglobin to change heme into methaemoglobin. Reduce the oxygen-carrying capacity of hemoglobin, the blood alkali storage and the oxidation performance of heme, resulting in anemia and tissue hypoxia. Ammonia is a recognized stress source and the most harmful gas in livestock and poultry houses. Ammonia can induce various respiratory diseases in poultry, pigs and other animals, and can induce or increase the incidence of broiler ascites. /kg ammonia concentration, will reduce the animal's resistance to infection. According to measurements, when the concentration of ammonia in the chicken house reaches 20mg/L, the incidence of various common diseases and frequently-occurring diseases will suddenly increase. As a result, the egg production of chickens will be reduced, and the weight gain and feed utilization efficiency of chicks will be greatly reduced. A poultry farm with a scale of 560,000 can discharge 10.5kg of ammonia gas per hour, and a pig farm with an annual output of 80,000 pigs can discharge more than 130kg of ammonia gas into the atmosphere per hour, and excessive ammonia gas emissions not only Caused a large amount of feed resource waste, and increased environmental pressure.
为此,人们对畜禽养殖舍内降低氨气含量控制开展了以下研究,研究一:通过合理控制畜禽日粮中蛋白质的摄入量,减少氨基酸在腐败微生物脲酶、尿酸酶的催化作用下水解生成氨气的量,同时在饲料中添加沸石粉、膨润土等硅酸盐类、发酵碳水化合物、酶制剂、植物提取物等降低氨气的产生量;研究二:降低粪便中的PH值,在粪板或粪池中撒布硫酸亚铁抑制粪便的发酵和分解,或者加入活菌制剂,从而有效减低了氨气的浓度;研究三:通过增加畜禽养殖舍高度,安装微电流抑菌抑氨系统、硫酸铵回收系统等方法来减少畜禽养殖舍内的氨气。For this reason, the following studies have been carried out on the control of reducing ammonia content in livestock and poultry breeding houses. Research 1: By reasonably controlling the intake of protein in livestock and poultry diets, reducing the amount of amino acids under the catalysis of spoilage microorganisms urease and uricase The amount of ammonia gas produced by hydrolysis, and at the same time adding zeolite powder, bentonite and other silicates, fermented carbohydrates, enzyme preparations, plant extracts, etc. Sprinkle ferrous sulfate in manure slabs or septic tanks to inhibit the fermentation and decomposition of manure, or add live bacteria preparations, thereby effectively reducing the concentration of ammonia; Study 3: By increasing the height of livestock and poultry breeding houses, installing micro-current antibacterial and antibacterial Ammonia system, ammonium sulfate recovery system and other methods to reduce ammonia gas in livestock and poultry breeding houses.
尽管这些研究成果对畜禽养殖舍氨气的消除和净化起到了一定的效果,但是其或操作复杂,或投资过大,能量消耗过多,不利于在广大畜禽养殖舍内的推广应用。在现有的畜禽养殖舍内大多还是利用氨气密度小于空气,分布于畜禽养殖舍上部,易溶于水的特点,通过用于养殖舍的氨气净化和收集装置来收集和净化氨气,现有的用于养殖舍的氨气收集装置大多结构复杂,不容易操作,收集氨气的水循环系统较差,严重影响了氨气的收集效果,无法达到现代畜禽养殖舍内低氨气含量的要求。Although these research results have a certain effect on the elimination and purification of ammonia in livestock and poultry breeding houses, the operation is complicated, or the investment is too large, and the energy consumption is too much, which is not conducive to the popularization and application in the vast number of livestock and poultry breeding houses. In the existing livestock and poultry breeding houses, the density of ammonia gas is lower than that of air, it is distributed in the upper part of the livestock and poultry breeding houses, and it is easily soluble in water. The ammonia gas purification and collection device used in the breeding houses is used to collect and purify ammonia. Most of the existing ammonia collection devices used in breeding houses have complex structures and are not easy to operate. The water circulation system for collecting ammonia is poor, which seriously affects the collection effect of ammonia, and cannot achieve low ammonia in modern livestock and poultry breeding houses. gas content requirements.

When the temperature is high, in order to achieve the best ventilation effect, the height of the outer air duct sleeved on the inner air duct should be raised so that the circular fixing hole on the upper part of the inner air duct is aligned with the circular fixing hole of the outer air duct, and Fixed by positioning pins, in winter or when the temperature in the breeding house is low, in order to enhance the heat preservation effect in the breeding house and greatly increase the ammonia concentration on the ground in the breeding house, it is necessary to lower the outer air duct on the inner air duct height, make the air duct close to the ground, make it easier for ammonia to enter the air duct, and at the same time align the circular fixing hole on the upper part of the inner air pipe with the circular fixing hole of the outer air pipe, and fix them with positioning pins, and then move toward the water curtain box Inject water into the water tank inside, and the water in the water tank will soak the bottom of the wet curtain plate, and at the same time, inject water into the annular water pipe from the water supply port, and the water will flow down from the bottom of the annular water pipe, so that the water curtain will be formed in the wet curtain plate, and the water curtain plate will The upper and middle parts are completely soaked, and the ammonia gas in the livestock and poultry breeding house is sucked into the water curtain box through negative pressure. When the total water volume is lower than the set value, the float switch sinks, and the water inlet system connected to the water inlet starts. At the same time, the water inlet valve is opened to add water to the water curtain box. When the water volume in the water curtain box reaches the set value, the floater The switch is turned off, the water inlet system is stopped, and the water inlet stops water intake, thereby ensuring the constant total water volume in the water curtain box. The circulating water in the tank absorbs ammonia gas many times, and the concentration of ammonia water continues to increase. The concentration of ammonia water is observed by the ammonia water density meter , when the required concentration of ammonia water is reached, the water outlet valve is opened to collect the ammonia water.
