Specific embodiments

[0032] The technical solutions in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. In the following description, a lot of specific details are set forth in order to give a full understanding of the utility model, but the utility model can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the utility model, therefore, the utility model is not limited by the specific embodiments disclosed below. Embodiments

[0033] As Figures 1-5 The embodiment provides a kind of organic waste gas catalytic combustion device, including case 1, as Figure 4As shown, the cabinet 1 is fixedly provided with a partition 2, the cabinet 1 has a hollow structure 10, and the hollow structure 10 is filled with heat preservation material. The cabinet 1 is made of stainless steel. The bottom of the cabinet 1 is fixedly provided with a support frame 8. The partition 2 divides the cabinet 1 into a left chamber 3 and a right chamber 4. The left chamber 3 and the right chamber 4 are both provided with a catalyst (not shown) and a plurality of heating rods 5. The heating rods 5 are electric heating rods 5. The heating rods 5 are of the prior art, and thus will not be described in detail. The organic waste gas catalytic combustion device further comprises a top pipe 6. The top pipe 6 is in communication with the top of the left chamber 3 and the right chamber 4 at two ends, and the top pipe 6 is fixedly penetrated through the partition 2. An air inlet hole 21 is formed in one side of the partition 2, the air inlet hole 21 is located at the bottom of the left chamber 3, and the top is in communication with an air outlet pipe 11. The bottom of the right chamber 4 is in communication with an air inlet pipe 12.

[0034] The heating rods 5 are driven to heat the left chamber 3 and the right chamber 4. After a certain temperature is reached, the organic waste gas enters the right chamber 4 through the air inlet pipe 12 and is catalytically combusted by the catalyst, thus forming a first catalytic combustion process. Further, the gas enters the left chamber 3 through the top pipe 6 and is catalytically combusted, thus forming a second catalytic combustion process. The gas enters the partition 2 through the air inlet hole 21, then enters the air outlet pipe 11 through the partition 2, and is discharged or enters the next process. By arranging the left chamber 3 and the right chamber 4 to perform two-stage catalytic combustion, the organic components in the waste gas can be gradually decomposed at different stages, improving the overall processing efficiency. Compared with a single combustion chamber, the problem of waste gas residue caused by incomplete one-time treatment is avoided, and the possibility of waste gas reaching the standard for emission is higher.

[0035] As shown in Figure 4 A plurality of bearing structures 7 are arranged in the height direction of the cabinet 1 in the left chamber 3 and the right chamber 4. The bearing structure 7 comprises two U-shaped plates 71 and a drawer shell 72 for filling the catalyst. The closed ends of the two U-shaped plates 71 are fixedly connected with the inner wall of the cabinet 1 or the outer wall of the partition 2, and the open ends of the two U-shaped plates 71 are oppositely arranged. The open end of each U-shaped plate 71 forms an insertion slot 73, and the insertion slot 73 is arranged in the width direction of the cabinet 1. The drawer shell 72 is inserted into the two insertion slots 73, and a plurality of air holes 720 are formed in the bottom wall of the drawer shell 72. Two switch doors 13 are arranged on the cabinet 1, and the two switch doors 13 correspond to the left chamber 3 and the right chamber 4, respectively. Each drawer shell 72 is filled with a catalyst.

[0036] As shown in Figures 2-5As shown, the organic waste gas catalytic combustion device further comprises a Y-shaped pipe 9, and the bottom of the left chamber 3 and the right chamber 4 are communicated with a hopper 91, respectively. The discharge port of the hopper 91 is communicated with two inclined pipe bodies of the Y-shaped pipe 9, respectively, and a switch valve 92 is arranged at the vertical pipe of the Y-shaped pipe 9. The switch valve 92 comprises two rotating shafts 920, a sliding rod 921 and a cylinder 923. The two rotating shafts 920 are rotatably arranged on the vertical pipe of the Y-shaped pipe 9, and the two rotating shafts 920 are arranged along the height direction of the machine box 1. A solid sleeve spur gear 924 is arranged at one end of each rotating shaft 920, and the other end of the rotating shaft 920 penetrates into the vertical pipe of the Y-shaped pipe 9. A plurality of arc-shaped buckets 925 are arranged on the circumference of the vertical pipe of the Y-shaped pipe 9. The two groups of arc-shaped buckets 925 divide the vertical pipe of the Y-shaped pipe 9 into an upper cavity 956, a middle cavity 957 and a lower cavity 958. The upper cavity 956 is communicated with the hopper 91. The support frame 8 has a mounting plate 81, and the mounting plate 81 is fixedly connected with the cylinder base of the cylinder 923. The piston rod of the cylinder 92 is fixedly connected with the sliding rod 921 through a connecting plate 959. The sliding rod 921 is slidably arranged on the mounting plate 81, and one end of the sliding rod 921 away from the connecting plate 959 is fixedly arranged with a vertical plate 950. The two ends of the vertical plate 950 are respectively fixedly arranged with an upper rack 9501 and a lower rack 9502. The upper rack 9501 can be engaged with one spur gear 924 through the cylinder 923, and the lower rack 9502 can be engaged with another spur gear 924 through the cylinder 923. If the catalytic combustion temperature of the organic waste gas is insufficient or the residence time is too short, part of the organic matter may not be completely oxidized, and carbon soot particles (such as carbon black) are generated. Or the waste gas contains inorganic particulate matter (such as metal dust, silicate) or salt (such as sulfate, chloride), and dust is left after combustion. The two inclined pipe bodies of the Y-shaped pipe 9 are connected with the hoppers 91 at the bottom of the left chamber 3 and the right chamber 4, respectively, for collecting particulate matter generated by the catalytic combustion of the organic waste gas after catalytic combustion. The arc-shaped buckets 925 of the two rotating shafts 920 are horizontally aligned, and the vertical pipe is divided into the upper cavity 956, the middle cavity 957 and the lower cavity 958. The passages of the middle cavity 957 and the lower cavity 958 are closed by the arc-shaped buckets 925. The dust of the waste gas after catalytic treatment in the combustion chamber enters the hopper 91, but due to the closing of the vertical pipe, it is temporarily stored in the upper cavity 956. The cylinder 923 pushes the sliding rod 921, the piston rod of the cylinder 923 is extended, the sliding rod 921 is pushed to move to one side, the upper rack 9501 on the vertical plate 950 is engaged with the spur gear 924 above. After the upper arc-shaped bucket 925 rotates, the dust is unloaded into the middle cavity 957. Further, the upper rack 9501 is not engaged with the spur gear 924, the piston rod of the cylinder 923 is continuously extended, the lower rack 9502 is engaged with the spur gear 924 below, and the spur gear 924 below drives the rotating shaft 920 to rotate, so that the dust enters the lower cavity 958 from the middle cavity 957. Through such a structure, it can be ensured that the left chamber 3 and the right chamber 4 are in a negative pressure state, and the dust can be discharged from the machine box 1.

[0037] Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.
