Abstract
Description
Technical Field
[0001] This utility model belongs to the field of waste gas treatment technology, specifically referring to a waste gas treatment device for animal protein processing. Background Technology
[0002] The waste gas from animal protein processing originates from raw material handling, processing, drying, and other processes. It mainly includes pollutants such as dust, volatile organic compounds (VOCs), ammonia, and hydrogen sulfide. Unlike general waste gas, the waste gas from animal protein processing contains dust, organic matter, and odorous gases simultaneously.
[0003] Existing waste gas treatment technologies for animal protein processing mostly employ spray towers to treat pollutants in the waste gas. This involves atomizing liquids containing different treatment agents and then contacting them with the gas inside the tower to achieve neutralization.
[0004] However, in actual use, in order to ensure the effect of waste gas treatment, the existing spray towers are made by adding multiple spray stages to ensure the treatment effect. This results in a large volume, greater difficulty in construction and maintenance, and correspondingly higher costs. Moreover, a single spray method is difficult to guarantee the effect of waste gas treatment, especially when treating waste gas from animal protein processing that contains dust, organic matter, and malodors. Utility Model Content
[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a waste gas treatment device for animal protein processing, which effectively solves the problems of large volume and difficult construction of existing waste gas treatment spray towers, as well as the problems of high construction and use costs, and the problems of fixed spraying, single form and poor treatment effect.
[0006] The technical solution adopted by this utility model is as follows: This utility model proposes a waste gas treatment device for animal protein processing, including a spray tower. An upper cover is fixed to the spray tower by bolts, and a gas collection hood is fixed in the middle of the upper end of the upper cover. A filter frame is fixed in the middle of the bottom of the upper cover. A rotating spray mechanism is provided at the lower end of the filter frame. An aeration disc is provided at the bottom of the spray tower, and a mixing mechanism is connected to the upper end of the aeration disc. The rotating spray mechanism includes a rotating joint rotatably connected to the middle of the bottom of the filter frame, and a water inlet pipe is rotatably connected to the upper end of the rotating joint. The other end of the water inlet pipe passes through the filter frame and the upper cover. A vertical water supply pipe is connected to the bottom of the rotating joint. The mixing mechanism consists of a guide rod, a lifting pipe, and a paddle. The guide rod is vertically fixed in the middle of the top of the aeration disc. The lifting pipe is sleeved on the upper end of the guide rod. The paddles are evenly distributed on the outer wall of the lifting pipe along the axis of the lifting pipe.
[0007] As an improvement to this solution, several spray pipes are evenly distributed along the circumference on the side wall of the water supply pipe, and spray pipes are evenly distributed vertically between each spray pipe and the water supply pipe. The spray pipes, spray pipes and water supply pipe are all interconnected.
[0008] As an improvement to this solution, two spiral slide rails are centrally symmetrically distributed on the inner wall of the lifting tube, and a rotating shaft is rotatably connected to the middle of the upper end of the lifting tube. Two sliding shafts are symmetrically fixed on the side wall of the rotating shaft, and the sliding shafts can slide along the contour of the spiral slide rails. A return spring is provided between the bottom of the protruding part of the upper end of the guide rod and the bottom of the inner wall of the lifting tube, and the return spring is arranged around the guide rod.
[0009] As an improvement to this solution, the inner wall of the spray tower is evenly distributed with fixed rods along the circumference, and each set of fixed rods is fixed with two symmetrical waterproof covers by bolts at one end near the axis of the spray tower. A sealing ring is provided at the joint of the two waterproof covers. A dual-output motor is fixed inside the waterproof cover, and the two output shafts of the dual-output motor pass through the upper and lower ends of the waterproof cover and are connected to the water supply pipe and the rotating shaft, respectively.
[0010] As an improvement to this solution, the lower end of the side wall of the spray tower is symmetrically connected with an inlet pipe and an outlet pipe.
[0011] As an improvement to this solution, an air inlet pipe is provided in the middle of the bottom of the spray tower, and the air inlet pipe is connected to the aeration disc. A baffle is fixed at the lower end of the side wall of the waterproof cover, and the baffle is distributed in an umbrella shape.
[0012] The beneficial effects of this utility model by adopting the above structure are as follows:
[0013] 1. Equipped with a rotating spray mechanism, the spray area can be effectively increased through the horizontally and vertically staggered spray pipes and nozzles on them, ensuring full contact with the exhaust gas. The rotation of the spray pipes reduces dead angles and further improves the uniform contact between the exhaust gas and the atomized liquid.
[0014] 2. By setting a mixing mechanism at the bottom of the spray tower tank, the periodically moving baffles can accelerate the flow of liquid at the bottom of the tank, making it come into uniform contact with the exhaust gas and improving the dust removal effect. The umbrella-shaped baffles ensure that the exhaust gas can come into full contact with the exhaust gas treatment liquid. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention proposes an exhaust gas treatment device for animal protein processing, including a spray tower 1, an upper end cover 2 fixed to the spray tower 1 by bolts, an air collection hood 3 fixed to the middle of the upper end of the upper end cover 2, a filter frame 4 fixed to the middle of the bottom of the upper end cover 2, a rotating spray mechanism 5 provided at the lower end of the filter frame 4, an aeration disc 6 provided at the bottom inside the spray tower 1, and a mixing mechanism 7 connected to the upper end of the aeration disc 6.
[0023] The rotating spraying mechanism 5 can uniformly spray the treatment liquid onto the exhaust gas in the spraying tower 1, improving the uniformity of contact. The mixing mechanism 7 at the bottom ensures that the incoming exhaust gas can fully contact the liquid, removing water-soluble pollutants.
[0024] like Figure 2 and Figure 4As shown, the rotary spraying mechanism 5 includes a rotary joint 8 rotatably connected to the middle of the bottom of the filter frame 4, and an inlet pipe 9 rotatably connected to the upper end of the rotary joint 8. The other end of the inlet pipe 9 passes through the filter frame 4 and the upper cover 2. A vertical water supply pipe 10 is connected to the bottom of the rotary joint 8.
[0025] Several spray pipes 14 are evenly distributed along the circumference on the side wall of the water supply pipe 10, and spray pipes 25 are evenly distributed vertically between each spray pipe 14 and the water supply pipe 10. The spray pipes 25, spray pipes 14 and water supply pipe 10 are all interconnected.
[0026] like Figure 2 and Figure 3 As shown, the mixing mechanism 7 consists of a guide rod 11, a lifting tube 12, and a paddle 13. The guide rod 11 is vertically fixed to the middle of the top of the aeration disc 6. The lifting tube 12 is sleeved on the upper end of the guide rod 11. The paddle 13 is evenly distributed on the outer wall of the lifting tube 12 along the axis of the lifting tube 12.
[0027] Two spiral slide rails 16 are centrally symmetrically distributed on the inner wall of the lifting tube 12, and a rotating shaft 17 is rotatably connected to the middle of the upper end of the lifting tube 12. Two slide shafts 18 are symmetrically fixed on the side wall of the rotating shaft 17, and the slide shafts 18 can slide along the contour of the spiral slide rails 16. A return spring 19 is provided between the bottom of the protruding part of the upper end of the guide rod 11 and the bottom of the inner wall of the lifting tube 12, and the return spring 19 is arranged around the guide rod 11.
[0028] like Figure 2 As shown, in order to drive the rotating spray mechanism 5 and the mixing mechanism 7, fixed rods 20 are evenly distributed along the circumference on the inner wall of the spray tower 1, and two symmetrical waterproof covers 21 are fixed to one end of each fixed rod 20 near the axis of the spray tower 1 by bolts. A sealing ring is provided at the joint of the two waterproof covers 21. A dual-output motor 22 is fixed inside the waterproof cover 21, and the two output shafts of the dual-output motor 22 pass through the upper and lower ends of the waterproof cover 21 respectively and are connected to the water supply pipe 10 and the rotating shaft 17.
[0029] like Figure 2 As shown, the lower end of the side wall of the spray tower 1 is symmetrically connected to the liquid inlet pipe 23 and the liquid outlet pipe 24.
[0030] In order to prolong the contact time between the exhaust gas and the liquid in the spray tower 1, an air inlet pipe 25 is provided in the middle of the bottom of the spray tower 1, and the air inlet pipe 25 is connected to the aeration disc 6. A baffle 26 is fixed at the lower end of the side wall of the waterproof cover 21, and the baffle 26 is distributed in an umbrella shape.
[0031] In practical use, clean water is introduced into the bottom of the spray tower 1 through the liquid inlet pipe 23 to filter dust in the exhaust gas, and discharged through the liquid outlet pipe 24 to maintain water cleanliness. Exhaust gas is introduced from the bottom of the spray tower 1 through the air inlet pipe 25 via the aeration plate 6. The exhaust gas enters the liquid at the bottom of the spray tower 1 through the aeration plate 6. The dual-output motor 22 is turned on to drive the rotating shaft 17 to rotate, causing the sliding shaft 18 on the side wall of the rotating shaft 17 to rotate. This forces the spiral slide rail 16 to drive the lifting pipe 12 to rise under the action of the contour. After the sliding shaft 18 separates from the spiral slide rail 16, it is reset by gravity and the return spring 19, realizing the up and down movement of the lever 13. This causes the liquid at the bottom of the spray tower 1 to flow faster, so that the introduced exhaust gas comes into full contact with the liquid, allowing the dust to dissolve in the water. Then the exhaust gas continues to rise. Under the obstruction of the baffle 26, it moves towards the inner wall of the spray tower 1 until it rises above the liquid surface. With the start of the dual-output motor 22, the water supply pipe 10 above rotates under its movement, causing the spray pipe 14 and spray pipe 15 on the side wall of the water supply pipe 10 to rotate synchronously. The external treatment liquid is sent into the rotary joint 8 through the water inlet pipe 9 and enters the water supply pipe 10 through the rotary joint 8. Finally, it is atomized and sprayed out from the nozzles on the spray pipe 15 and spray pipe 14. The atomized liquid comes into uniform contact with the dust-removed exhaust gas during the rotation of the water supply pipe 10. After the reaction, it is filtered through the filter frame 4 and the filter medium inside it and then discharged from the gas collection hood 3. The filter medium can be replaced by opening the upper cover 2 periodically. The above is the entire process of using the exhaust gas treatment device for animal protein processing.
[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
