[0039] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and arrangements of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application.
[0040] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0041] Referring to Figure 1 and Figure 2 The present application provides a large-scale farm deodorization device, comprising:
[0042] The deodorization room 20 is arranged in the breeding farm 10 partition wall, and is used for sealing the outlet of all ventilation machines 11 of the breeding farm 10 to gather the odor generated by the breeding farm 10;
[0043] The wet curtain deodorization wall 30 is used as the wall body of the deodorization room 20 away from the breeding farm 10, has a wet curtain 31; and
[0044] A spraying system 40 is arranged in the deodorization room 20 and located at the windward side of the wet curtain deodorization wall 30.
[0045] The spraying system 40 is provided with a transverse spray pipe 41 and a plurality of longitudinal spray pipes 42 hung below the transverse spray pipe 41 and communicated with the transverse spray pipe 41 respectively, and a plurality of nozzles 43 are connected to each longitudinal spray pipe 42 at equal intervals. The nozzles 43 can spray deodorization liquid to soak and wet the wet curtain 31 so as to realize deodorization of odor under the action of the ventilator 11.
[0046] Specifically, the deodorization room 20 shares a wall with the breeding farm 10, and all the ventilators 11 of the breeding farm 10 are installed on the wall with outlets facing the deodorization room 20. A rain shed is arranged above the deodorization room 20 to form a closed space. The wet curtain deodorization wall 30 is arranged below the lower end of the rain shed and opposite to the outlets of the ventilators 11. In operation, the spraying system 40 is first started to spray deodorization liquid through the nozzles 43 to soak and wet the wet curtain 31. Then, the ventilators 11 are started, and the odor generated in the breeding farm 10 enters the deodorization room 20 and blows to the wet curtain deodorization wall 30 under the action of the ventilators 11. The odor contacts the wet curtain 31 and reacts with the deodorization liquid to complete deodorization, and is discharged into the air after deodorization. That is, the deodorization room 20 and the wet curtain 31 soaked with the deodorization liquid can increase the residence time of the odor, increase the solubility of inorganic malodorous substances such as ammonia and hydrogen sulfide in the odor, and achieve the purpose of treating organic malodorous substances in the odor. The deodorization effect is good, which can effectively reduce the emission concentration of the odor and thus reduce the pollution of the surrounding environment.
[0047] The deodorization room 20 is provided with a maintenance door 21 for cleaning, maintenance of the spraying system 40 and replacement of the wet curtain 31.
[0048] In this embodiment, the deodorization room 20 has a size of 3-8 m in width, 35-45 m in length and 4-6 m in height.
[0049] The wet curtain deodorization wall 30 includes a base 32 arranged on the ground and a support (not shown in the figure) arranged above the base 32, and the wet curtain 31 is installed on the support.
[0050] In this embodiment, the material of the wet curtain 31 is copolymerized polypropylene. Specifically, the wet curtain 31 is 4-6 m away from the outlet of the ventilator 11, and has a size of 40-60 cm in thickness, 35-45 m in length and 4-6 m in height.
[0051] The transverse spray pipe 41 is parallel to the wet curtain 31, and the distance between the transverse spray pipe 41 and the wet curtain 31 is 0.5-1.5 m. The longitudinal spray pipes 42 are 14-18 in number, arranged in a straight line at equal intervals and with the lower ends 1 m above the ground. Each longitudinal spray pipe 42 is connected to 3-6 nozzles 43.
[0052] In the embodiment, the nozzle 43 is preferably a PVC spiral nozzle.
[0053] The large-scale breeding farm deodorization device further comprises a deodorizing circulating pool 50 for providing the spraying system 40 with deodorizing liquid, which is arranged on one side of the base 32 and in the deodorization room 20, and is used for adding deodorizing agent to mix with tap water in the pool to form deodorizing liquid. Specifically, the deodorizing circulating pool 50 is internally sequentially provided with a circulating pump 51 and an impurity filter 52, and the impurity filter 52 is communicated with the transverse spray pipe 41 through an upwardly extending branch pipe 53. In operation, according to the odor concentration and the dosage requirement, the deodorizing agent is added into the deodorizing circulating pool 50 to dilute 300-500 times to obtain the deodorizing liquid, which is pumped into the spraying system 40 through the circulating pump 51 and the impurity filter 52, and then the deodorizing liquid is sprayed to the wet curtain 31 in an intermittent spraying mode through the nozzle 43, so as to ensure the effective treatment of the deodorizing liquid to the odor, and effectively reduce the ammonia concentration by 90%; and the excess deodorizing liquid flows into the deodorizing circulating pool 50 again along the wet curtain 31 to be collected for recycling, which can effectively reduce the water consumption by 10%-15%.
[0054] In the embodiment, the size of the deodorizing circulating pool 50 is 13-23 m in length, 0.8-1.8 m in width, and 0.3-0.6 m in height.
[0055] The deodorizing circulating pool 50 is communicated with a water mist collecting pool 60 provided with an absorption rod 61, which is arranged on the other side of the base 32 and outside the deodorization room 20, and the absorption rod 61 is used for absorbing the liquid blown away from the wet curtain 31 by the ventilator 11 to flow back to the deodorizing circulating pool 50 from the low end of the inclined pool bottom of the water mist collecting pool 60. Specifically, the pool bottom of the water mist collecting pool 60 has a certain slope, and the lower end thereof is communicated with the deodorizing circulating pool 50; after the absorption rod 61 absorbs the liquid blown away from the wet curtain 31 by the ventilator 11, it is saturated, and then the liquid drips into the water mist collecting pool 60 along the absorption rod 61 under the action of gravity, and then flows back to the deodorizing circulating pool 50 from the low end of the pool bottom. Through the deodorizing circulating pool 50 and the water mist collecting pool 60, the effective treatment of the deodorizing liquid to the odor can be ensured, and at the same time, the deodorizing liquid after spraying can be collected to the maximum extent to realize recycling, which greatly saves the water consumption, effectively relieves the pressure of subsequent sewage treatment, and saves the operation cost.
[0056] The large-scale breeding farm deodorization device further comprises a control system (not shown in the figure), which is electrically connected with the circulating pump 51 and is used for controlling the spraying time and state of the spraying system 40. The spraying time is adjusted according to the season, and the spraying state is divided into continuous spraying and intermittent spraying. In operation, the running status of the nozzle 43 needs to be checked regularly and water needs to be supplemented in time: generally, the deodorizing liquid in the deodorizing circulating pool 50 needs to be replaced once every 5-15 days, and the nozzle 43 needs to be cleaned once a month; the water consumption is larger in summer and smaller in winter, so the water supplement frequency is higher in summer.
[0057] The above embodiments are only preferred embodiments of the present application, and are not intended to limit the technical solutions of the present application. Any technical solutions that can be realized on the basis of the above embodiments without creative labor should be considered to fall within the scope of protection of the patent of the present application.
