Description
Technical Field
The invention relates to the technical field of ammonia-reducing and deodorizing of large-scale livestock farms, in particular to an automatic spraying device for ammonia-reducing and deodorizing agents of farms and a control method.
Background
Along with the rapid development of large-scale livestock breeding, the density of livestock breeding is also continuously increased, a large-scale livestock farm begins to face a series of new problems, wherein one of the outstanding problems restricting the healthy development of the livestock farm is the problem of air pollution in the livestock house of the livestock farm, the air quality in the livestock house can influence the living state, the growth process and the like of the livestock, in addition, the air pollutants discharged by the livestock farm can influence the surrounding ecological environment quality, and especially the ammonia in the air pollutants has larger influence on the livestock breeding and the surrounding ecological environment, so that the healthy development of the livestock farm is severely restricted.
Ammonia gas (English name Ammonia, chemical formula NH) 3 ) Has strong pungent smell, has density of 0.7710g/L, relative density 0.5971 (air=1.00), is easy to liquefy into colorless liquid, can liquefy under normal temperature and pressure (critical temperature 132.4 ℃ C., critical pressure 11.2 megapascals, namely 112.2 atm), boiling point-33.5 ℃ C., is easy to solidify into snow-like solid, melting point-77.75 ℃ C., and is dissolved in water, ethanol and diethyl ether. Can be decomposed into nitrogen and hydrogen at high temperature, has reduction effect, can be oxidized into nitric oxide in the presence of catalyst, can be used for preparing liquid nitrogen, ammonia water, nitric acid, ammonium salt, amine and the like, can be prepared by directly synthesizing nitrogen and hydrogen, can burn mucous membranes of skin, eyes and respiratory organs, is inhaled by people too much, can cause lung swelling and death.
The ammonia in the farm is mainly produced by decomposing nitrogen-containing organic matters in livestock manure under the action of urease, and NH 3 The generation of the catalyst occurs in each link of the management of the livestock breeding manure, and a large amount of NH is generated in the livestock houses, the livestock manure storage and treatment sites and the manure returning application process 3 Volatilizing into the surrounding environment, there are studies showing that animal-emitted ammonia accounts for 50% of the total world, about 80% in the united states and about 90% in europe. A large amount of animal excreta in a farm generate ammonia gas and emit odor every day, so that the environment is greatly influenced, and the reaction product of the ammonia gas is also the main component of PM2.5, and about 50% of PM2.5 in the United states is detected as ammonia gasAnd (3) forming a derivative.
The aqueous ammonia solution is alkaline and irritating to mucous membranes, and when severe, alkali burn can occur, causing tearing, burning pain, inflammation of cornea and conjunctiva, and vision disorder. In the livestock and poultry house, ammonia can stimulate the outer crude membrane of livestock and poultry to cause mucous membrane congestion and laryngeal edema, ammonia enters the respiratory tract to cause cough, tracheal stricture, bronchitis, even dyspnea, asphyxia and other symptoms, high-concentration ammonia can directly stimulate body tissues to cause symptoms such as central nervous system paralysis, and the livestock can be in an environment with low-concentration ammonia for a long time to cause physical weakness and life activity reduction. Researches show that when 50mg/L ammonia is contained in the air of the living environment of the young pigs, the weight of the young pigs is reduced by 12 percent, when 100mg/L ammonia is contained, the ammonia is reduced by 30 percent, when the ammonia concentration in the chicken house reaches 20mg/L, the morbidity of coccidiosis and the like is obviously increased, and when the concentration is increased to 50mg/L, the mucous membrane congestion and edema of the respiratory tract can be caused, and bronchitis, pneumonia, emphysema, central nerve paralysis and the like can occur. In addition if the person is exposed to very low concentrations (0.3 mg/L) of NH over a long period of time 3 The environment is harmful to health, and only NH in the air 3 The concentration is higher than 50mg/L, so that the human perception can be realized. Therefore, the massive volatilization of ammonia and odor in the large-scale farm threatens the healthy growth of livestock and animals and seriously affects the health of human beings.
At present, measures for reducing the ammonia concentration and deodorizing in a farm comprise spraying a deodorizing agent, using an environment-friendly strong-adsorbability material as a building material of the farm, ventilating in time, improving a ration formula and the like, wherein the deodorizing agent is widely applied as an effective means for reducing the ammonia concentration in a livestock house. The deodorant can be divided into chemical deodorant, biological deodorant, plant deodorant and the like according to the components, and can be divided into liquid deodorant and solid deodorant according to the form, wherein the liquid deodorant is convenient to spray, but has obvious defects that: the water mist formed by the liquid deodorant during spraying can cause overlarge local humidity of a farm, and can cause adverse effects on animal health. From the aspects of the overall effect of ammonia reduction and deodorization and energy conservation and environmental protection, the solid biological deodorant is a novel product at present, most solid biological deodorants utilize probiotics to reduce ammonia and deodorize, have no influence on the environment, are very beneficial to environmental protection and have obvious deodorizing and ammonia reducing effects, but have the defects of needing manual operation in spraying, having high labor intensity, easily causing uneven spraying and waste and having higher requirements on the operation standard degree of operators. At present, the field of large-scale farms does not find out the special ammonia-reducing deodorizing automatic equipment, and the large-scale farms are urgently required to achieve the optimal spraying effect, and manual automatic devices can be saved to a great extent to solve the problems.

After the blanking is finished, the controller controls the air electromagnetic valve 9 to be opened, compressed air enters the air spray pipe 10, and is sprayed out by the air nozzle 11 at the air outlet end of the air spray pipe 10 and blows off dry powder in the quantitative storage tank 12 to form uniform powder fog, and the controller opens the air electromagnetic valve 9 and simultaneously opens the electromagnetic regulating valve 13 to ensure that the powder fog enters the spraying pipeline 14 and is sprayed out by the nozzle 15.
In addition, as shown in fig. 1, the controller can remotely control through APP software on the mobile phone, so as to remotely control the start and stop of the gear motor 1 or adjust the rotation speed, and the controller is controlled by using the mobile phone APP software and is a well-known technology in the art.
The invention is convenient to install, can be adjusted according to different places, take a large-scale pig farm as an example, each pig farm or a group of pig farms can be assembled in each colony house, if the pig farm is provided with a slotted floor, pipelines can be arranged at any height above the slotted floor, pipelines are arranged 5-10 cm deep below the slotted floor, nozzles can spray in any direction, such as under the slotted floor, 45-degree spraying is performed obliquely, ammonia-reducing deodorant can be settled on the slotted floor after being sprayed out, and can also be settled to a excrement drainage ditch from the slotted position of the slotted floor, thus the ammonia emission on the floor and the ground can be comprehensively controlled, and the invention has the advantages that the pipeline is arranged in such a way that the spraying action is small, stress to piglets can be effectively prevented, the pipelines are distributed in the chicken farm, and only the chicken flocks can be effectively prevented. In addition, if the livestock shed uses the liquid ammonia-reducing deodorant, the air electromagnetic valve 9 can be closed, a pipeline pump is added on the material pipeline 17 between the rear of the electromagnetic regulating valve 13 and the spraying pipeline 14, and the pipeline pump can be directly controlled by the controller to pump and spray the liquid ammonia-reducing deodorant liquid.
