Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology for organic fertilizer fermentation tanks, specifically a waste gas treatment device for organic fertilizer fermentation tanks. Background Technology

[0002] Organic fertilizer refers to carbon-containing materials primarily derived from plants and / or animals, applied to the soil to provide nutrients to plants. It is produced through the processing of biological matter, animal and plant waste, and plant residues, eliminating toxic and harmful substances and enriching it with numerous beneficial substances. It is a key nutrient source for green food production. During the fermentation process of organic fertilizer, the fermentation tank generates a large amount of waste gas. This waste gas needs to be treated by a treatment device; otherwise, it will not only pollute the environment but also affect the health of people in the surrounding area.

[0003] The State Intellectual Property Office has granted patent "201621200998.0", entitled "An Exhaust System for an Organic Fertilizer Fermentation Tank". The disclosed exhaust system includes a horizontal main exhaust pipe laid on top of a trough-shaped fermentation tank. The horizontal main exhaust pipe has branch exhaust pipe interfaces corresponding to each trough-shaped fermentation tank. The longitudinal branch pipes have evenly distributed air intake and exhaust ports. The exhaust end of the horizontal main exhaust pipe is connected to the inlet of an activated carbon box via a pipe. The activated carbon box has at least two layers, each layer equipped with drawers for holding activated carbon. The outlet of the activated carbon box is located on the second layer and connects to a blower.

[0004] In the comparative patent, the waste gas in the organic fertilizer fermentation tank is purified by setting up an activated carbon box. However, since the waste gas in the organic fertilizer fermentation tank is continuous, the activated carbon in the activated carbon box will always be adsorbing, which will reduce its service life and require frequent replacement of the activated carbon. Therefore, it is not only troublesome and laborious, but also has a relatively high cost. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a waste gas treatment device for organic fertilizer fermentation tanks, which solves the problem that the exhaust system in existing organic fertilizer fermentation tanks requires frequent replacement of activated carbon, which is not only troublesome and laborious but also has relatively high operating costs.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a waste gas treatment device for an organic fertilizer fermentation tank, comprising a treatment box, two pairs of supports fixedly connected to the upper end of the treatment box, a filling layer snapped onto adjacent supports, a first water pipe fixedly connected to the treatment box above the filling layer, a plurality of atomizing spray heads connected to the bottom end of the first water pipe, a UV photolysis box fixedly connected to the outer side wall of the treatment box, a liquid supply mechanism installed at the end of the first water pipe located outside the treatment box, and a suction mechanism installed at the top of the treatment box.

[0007] Preferably, the liquid supply mechanism includes a horizontal plate fixed to the outer wall of the side of the treatment tank, and a water pump is fixed inside the horizontal plate. The inlet and outlet of the water pump are respectively fixed to a second water pipe and a third water pipe, and the third water pipe is connected to the first water pipe.

[0008] Preferably, the air intake mechanism includes a fan fixedly connected to the top of the processing box, and the air intake and air outlet of the fan are respectively fixedly connected to a first air pipe and a second air pipe. The end of the first air pipe away from the fan passes through the processing box and is connected to a gas collection hood, and the end of the second air pipe away from the fan is connected to the inside of the UV photolysis box.

[0009] Preferably, an air inlet pipe and a liquid outlet pipe are fixedly connected to the bottom of the processing box.

[0010] Preferably, a cross disc is fixedly connected to the center of the interior of the processing box, and a guide fan blade is rotatably connected above the cross disc.

[0011] Preferably, the front end face of the processing box is connected to a box plate by a number of bolts.

[0012] Beneficial effects

[0013] This utility model provides a waste gas treatment device for organic fertilizer fermentation tanks, which has the following beneficial effects:

[0014] When the waste gas from the organic fertilizer fermentation tank is discharged into the treatment chamber through the inlet pipe, the rising waste gas will drive the guide fan blades to rotate. The guide fan blades can make the waste gas from the organic fertilizer fermentation tank flow upward evenly. The waste gas then passes through the filling layer and further diffuses into the treatment chamber. Then, the water pump is started. The water pump can draw in the treatment liquid through the second water pipe, and then discharge it into the first water pipe through the third water pipe. Finally, it is sprayed out through the atomizing spray head below the first water pipe, which can better contact the waste gas from the organic fertilizer fermentation tank, thereby adjusting the pH value in the waste gas and neutralizing it, thus achieving preliminary treatment. At the same time, the liquid in the treatment chamber can be discharged through the drain pipe to the external filter structure for filtration and recycling. Then, the blower is started, and the blower draws in the waste gas that has completed the neutralization reaction in the treatment chamber through the first air pipe and the gas collection hood, and then discharges the gas into the UV photolysis chamber for pyrolysis and purification through the second air pipe. This eliminates the need for frequent replacement, which is not only simple and labor-saving, but also reduces costs. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4This utility model provides a technical solution: a waste gas treatment device for an organic fertilizer fermentation tank, including a treatment box 1. Two pairs of supports 2 are fixedly connected to the upper end of the treatment box 1. A filling layer 3 is snapped onto the adjacent supports 2.

A liquid supply mechanism is installed at the end of the first water pipe 4 located outside the treatment box 1. An air suction mechanism is installed at the top of the treatment box 1.

[0022] A filling layer 3 is snapped onto the support 2. The filling layer 3 is made of ceramic filler, which has good corrosion resistance and heat resistance, is inexpensive, and has good surface wettability, which can enable the neutralized liquid and the waste gas to have better contact and reaction.

[0023] In this embodiment, the liquid supply mechanism includes a horizontal plate 7 fixedly connected to the outer wall of the side of the treatment tank 1, and a water pump 8 is fixedly connected inside the horizontal plate 7. The inlet and outlet of the water pump 8 are respectively fixedly connected to a second water pipe 9 and a third water pipe 10, and the third water pipe 10 is connected to the first water pipe 4.

[0024] The upper part of the third water pipe 10 is a closed design. When the water pump 8 is started, the water pump 8 can draw in the liquid to be treated through the second water pipe 9, and then discharge it into the first water pipe 4 through the third water pipe 10. Finally, it is sprayed out through the atomizing spray head 5 below the first water pipe 4.

[0025] In this embodiment, the suction mechanism includes a fan 11 fixedly connected to the top of the processing box 1, and the suction port and the exhaust port of the fan 11 are respectively fixedly connected to a first air pipe 12 and a second air pipe 13. The end of the first air pipe 12 away from the fan 11 passes through the processing box 1 and is connected to the gas collection hood 14. The end of the second air pipe 13 away from the fan 11 is connected to the inside of the UV photolysis box 6.

[0026] The fan 11 can be started, so that the fan 11 can draw in the waste gas that has completed the neutralization reaction in the treatment box 1 through the first air pipe 12 and the gas collection hood 14, and then discharge the gas into the UV photolysis box 6 through the second air pipe 13 for pyrolysis and purification.

[0027] In this embodiment, the bottom of the processing box 1 is further configured to have an air inlet pipe 15 and a liquid outlet pipe 16 fixedly connected to it.

[0028] Several openings are machined at the bottom of the intake pipe 15 so that exhaust gas can be discharged from the openings at the bottom of the intake pipe 15. At the same time, this design can also minimize the flow of liquid into the intake pipe 15.

[0029] In this embodiment, a cross disk 17 is fixedly connected to the middle of the interior of the processing box 1, and a guide fan blade 18 is rotatably connected above the cross disk 17.

[0030] In this embodiment, the front end face of the processing box 1 is further configured such that a box plate 19 is threadedly connected to it by several bolts.

[0031] It is worth noting that the electrical structures and other components involved in this application can be selected according to the user's needs, as long as they meet the requirements of this application. At the same time, the corresponding control circuits and other components are all existing technologies, which can be fully implemented by those skilled in the art, so they will not be described in detail here.

[0032] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0033] Example: When this device is needed, the second water pipe 9 can be connected to the structure supplying neutralizing liquid from the outside, and the air inlet pipe 15 can be connected to the external organic fertilizer fermentation tank exhaust gas supply structure. When the exhaust gas from the organic fertilizer fermentation tank is discharged into the treatment tank 1 through the air inlet pipe 15, the rising exhaust gas will blow the guide fan blades 18 to rotate. The guide fan blades 18 can make the exhaust gas from the organic fertilizer fermentation tank flow upward evenly. The exhaust gas then passes through the filling layer 3 and further diffuses into the treatment tank 1. After that, the water pump 8 is started. The water pump 8 can draw in the treatment liquid through the second water pipe 9, and then discharge it into the first water pipe 4 through the third water pipe 10. Finally, it is discharged into the first water pipe 4 through the first water pipe 10. The atomizing spray head 5 below pipe 4 sprays out to make better contact with the waste gas from the organic fertilizer fermentation tank, thereby adjusting the pH value of the waste gas and neutralizing it to achieve preliminary treatment. At the same time, the liquid in the treatment tank 1 can be discharged to the external filter structure through the drain pipe 16 for filtration and recycling. Then, the blower 11 is started, which draws the waste gas that has completed the neutralization reaction in the treatment tank 1 through the first air pipe 12 and the gas collection hood 14, and then discharges the gas into the UV photolysis box 6 through the second air pipe 13 for pyrolysis and purification. This eliminates the need for frequent replacement, which is not only simple and labor-saving, but also reduces costs.
