Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device in the production of peony extract. Background Art

[0002] Peony is a kind of flower and an important Chinese medicinal material. It is praised as "Flower Fairy" and "Flower Phase" and is listed as one of the "Top Ten Famous Flowers". Peony root is also a medicinal material. Peony extract is a water-extracted alcohol from peony root and flower. The main active ingredients are paeoniflorin and gallic acid compounds, which have the effects of dilating blood vessels, lowering blood pressure and relieving pain, clearing away heat and relieving spasms, and have high medicinal value. Exhaust gas will be generated during peony extraction. In order to avoid environmental pollution caused by exhaust gas, a dedicated exhaust gas treatment device is required to treat the exhaust gas.

[0003] However, when the exhaust gas treatment device in the prior art performs oxidation reaction treatment on the exhaust gas, the amount of catalyst is often difficult to control, and it is difficult to control the amount of catalyst added according to the overall exhaust gas. In addition, the treatment method is relatively single, and it is impossible to ensure that the harmful substances in the exhaust gas are completely removed;

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a waste gas treatment device in the production of peony extract, which first passes the waste gas into a wet treatment chamber, and then enters the oxidation reaction chamber after the waste gas is double treated with a solvent and an activated carbon net. At this time, the quantitative feeding mechanism is started to control the feeding amount of the catalyst according to the total amount of the waste gas to ensure that there is not too much or too little catalyst, and then the waste gas is oxidized, thereby forming a triple treatment of the waste gas to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a waste gas treatment device in the production of peony extract, comprising a treatment box, an oxidation treatment chamber and a wet treatment chamber are respectively opened on both sides of the treatment box, a catalyst unloading box is fixed at a position corresponding to the oxidation treatment chamber on the upper surface of the treatment box, and an observation window is fixed at a position corresponding to the oxidation treatment chamber at the front end of the treatment box, a quantitative unloading mechanism is installed inside the catalyst unloading box, a heating net is fixed inside the oxidation treatment chamber, and a combustion bed fixed inside the oxidation treatment chamber is arranged at the bottom of the heating net;

[0007] A solvent box is fixed to the inner bottom of the wet processing chamber, an air inlet penetrating through and extending to the outside of the processing box is fixed to one side of the solvent box, and a solvent inlet and outlet are fixed to the front end of the solvent box.

[0008] Furthermore, the quantitative feeding mechanism includes a screen arranged inside the catalyst feeding box, a plurality of springs are symmetrically fixed on both sides of the screen inside the catalyst feeding box, a connecting rod is rotatably connected to one side of the bottom of the catalyst feeding box, an eccentric block is rotatably connected to one side of the connecting rod, a rotating shaft is fixed to the rear end of the eccentric block, and a first motor is fixed to the rear end of the rotating shaft, which penetrates through and extends to the outside of the catalyst feeding box.

[0009] Furthermore, two guide plates are symmetrically fixed on both sides of the catalyst feed box at positions below the screen, and a feed cavity is opened at the middle position of the two guide plates corresponding to the inner bottom layer of the catalyst feed box, and the feed cavity has a circular structure.

[0010] Furthermore, an auger is rotatably connected to the interior of the material discharge chamber, the size of the auger is adapted to the internal size of the material discharge chamber, and the front end of the auger penetrates and extends to the outside of the catalyst material discharge box where a second motor is fixed.

[0011] Furthermore, two limit slide grooves are symmetrically opened at the upper position of the solvent box on both sides of the interior of the wet treatment chamber, and the limit slide grooves are internally slidably connected to the limit sliders. A mounting plate is commonly fixed between the two limit sliders, and an activated carbon net is fixed inside the mounting plate.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] 1. The utility model is provided with a quantitative feeding mechanism. When the exhaust gas is subjected to oxidation reaction, the first motor drives the rotating shaft to rotate, and then drives the eccentric disk to rotate, thereby forming a swing of the connecting rod. The swing of the connecting rod cooperates with the spring to drive the screen plate to form an irregular vibrating effect, thereby screening the catalyst. The screened catalysts are of similar size and are easier to burn. As the second motor drives the auger to rotate, the catalyst is driven to fall into the oxidation reaction chamber at a uniform speed. Since the catalysts are of similar size, the problem of some catalysts being too large to be difficult to burn or excessive waste will not occur. The feeding amount of the catalyst is controlled according to the treatment amount of the exhaust gas.

[0014] 2. The utility model is provided with a wet treatment chamber, which directly passes the exhaust gas into the solvent box, and the exhaust gas contacts the solvent to absorb or dissolve the gaseous pollutants in the exhaust gas. The treated exhaust gas is then filtered and adsorbed by the activated carbon net to remove the odor, volatile organic matter, etc. in the exhaust gas, so as to form a pretreatment of the exhaust gas, which is convenient for the subsequent oxidation reaction. After the activated carbon net is used for a long time, it can be quickly withdrawn through the limit slide and the limit slider, so as to replace it and ensure the subsequent filtering and adsorption effect.

[0015] To summarize, the utility model first passes the exhaust gas into the wet treatment chamber, and the exhaust gas enters the oxidation reaction chamber after dual treatment with the solvent and the activated carbon net. At this time, the quantitative feeding mechanism is started to control the feeding amount of the catalyst according to the total amount of the exhaust gas to ensure that there is not too much or too little catalyst, and then the exhaust gas is oxidized, thereby forming a triple treatment of the exhaust gas to ensure its treatment effect.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] This embodiment aims to solve the problem that when the exhaust gas treatment device in the prior art performs oxidation reaction treatment on the exhaust gas, the amount of catalyst is often difficult to control, and it is difficult to control the amount of catalyst added according to the overall exhaust gas.

[0025] like Figure 1-3As shown, a waste gas treatment device in the production of peony extract includes a treatment box 1, an oxidation treatment chamber 10 and a wet treatment chamber 11 are respectively opened on both sides of the treatment box 1, an exhaust port is fixed at a position close to the oxidation treatment chamber 10 on one side of the treatment box 1, a catalyst unloading box 2 is fixed at a position corresponding to the oxidation treatment chamber 10 on the upper surface of the treatment box 1, and an observation window 4 is fixed at a position corresponding to the oxidation treatment chamber 10 on the front end of the treatment box 1, and a quantitative unloading mechanism 3 is installed inside the catalyst unloading box 2;

[0026] The quantitative feeding mechanism 3 includes a screen 13 arranged inside the catalyst feeding box 2, and a plurality of springs 20 are symmetrically fixed on both sides of the screen 13 inside the catalyst feeding box 2. A connecting rod 22 is rotatably connected to one side of the bottom of the catalyst feeding box 2. The swing of the connecting rod 22 drives the screen 13 to shake, and cooperates with the reset effect of the spring 20 to form a vibrating screen. An eccentric block 21 is rotatably connected to one side of the connecting rod 22. When the eccentric block 21 rotates, the connecting rod 22 rotates with the eccentric block 21 to form a circular motion, thereby driving the other side to swing. A rotating shaft 19 is fixed to the rear end of the eccentric block 21, and a first motor 14 that penetrates and extends to the outside of the catalyst feeding box 2 is fixed to the rear end of the rotating shaft 19.

[0027] Two guide plates 15 are symmetrically fixed on both sides of the interior of the catalyst unloading box 2 at positions below the screen 13. A certain cavity is provided between the screen 13 and the guide plates 15 to facilitate the storage of the screened catalyst. A unloading cavity 17 is provided at the middle position of the two guide plates 15 corresponding to the inner bottom of the catalyst unloading box 2. The unloading cavity 17 is of a circular structure. An auger 18 is rotatably connected to the interior of the unloading cavity 17. The size of the auger 18 is adapted to the inner size of the unloading cavity 17.

[0028] Because the size of the discharge chamber 17 is adapted to that of the auger 18, the catalyst will fall into the processing box 1 through the discharge chamber 17 only when the auger 18 rotates, and the front end of the auger 18 penetrates and extends to the catalyst discharge box 2, where a second motor 16 is fixed to the outside. A heating net 8 is fixed to the inside of the oxidation treatment chamber 10, and the internal mesh size of the heating net 8 is smaller than the internal mesh size of the mesh 13. The screened catalyst falls onto the upper surface of the heating net 8 and is heated by the combustion bed 9. The bottom of the heating net 8 is provided with a combustion bed 9 fixed to the inside of the oxidation treatment chamber 10.

[0029] When the exhaust gas is subjected to oxidation reaction treatment, the first motor 14 is started to drive the rotating shaft 19 to rotate, thereby driving the eccentric block 21 to rotate. The rotation of the eccentric block 21 drives the connecting rod 22 to swing. The connecting rod 22 cooperates with the spring 20 to drive the screen 13 to form a vibrating screen effect, thereby screening out the catalyst, which is of similar size and easy to burn;

[0030] Then, the second motor 16 is started to drive the feed chamber 17 to rotate. According to the total amount of exhaust gas, the rotation time and speed of the second motor 16 are controlled, thereby controlling the amount of catalyst fed. The catalyst falls onto the upper surface of the heating net 8, and the combustion bed 9 is started to heat the catalyst on the upper surface of the heating net 8. When the exhaust gas enters the oxidation treatment chamber 10, the exhaust gas is oxidized.

[0031] Embodiment 2:

[0032] This embodiment aims to solve the problem that the treatment method of the exhaust gas treatment device in the prior art is relatively simple and cannot ensure that the harmful substances in the exhaust gas are completely removed.

[0033] like Figure 4-5 As shown, the embodiment is a waste gas treatment device in the production of peony extract, and a solvent box 5 is fixed to the inner bottom of the wet treatment chamber 11, and an air inlet 7 that penetrates and extends to the outside of the treatment box 1 is fixed on one side of the solvent box 5, and a solvent inlet and outlet 24 is fixed at the front end of the solvent box 5, and a sealing valve is arranged inside the solvent inlet and outlet 24 to prevent leakage. Two limiting slide grooves 25 are symmetrically opened at the upper positions of the solvent box 5 on both sides of the interior of the wet treatment chamber 11 corresponding to the internal sliding connection of the limiting slide groove 25, and a limiting slider 23 is provided inside the limiting slider 25. A mounting plate 6 is fixed between the two limiting sliders 23, and a handle is fixed at the front end of the mounting plate 6 to facilitate the removal of the mounting plate 6. An activated carbon net 12 is fixed inside the mounting plate 6, and the activated carbon net 12 and the mounting plate 6 can be quickly disassembled for easy replacement.

[0034] The waste gas enters the solvent box 5 through the air inlet 7. The waste gas dissolved and absorbed by the solvent floats up and passes through the activated carbon net 12, which adsorbs the odor and volatile organic matter in the waste gas. After long-term use, the mounting plate 6 is pulled out by the handle, and the mounting plate 6 cooperates with the limiting slider 23 to be pulled out along the limiting slide groove 25, so as to replace the activated carbon net 12 after long-term use to ensure the subsequent adsorption effect.

[0035] Working process and principle of this utility model:

[0036] Step 1: The exhaust gas enters the solvent box 5 through the air inlet 7. The exhaust gas dissolved and absorbed by the solvent floats up and passes through the activated carbon net 12, which adsorbs the odor and volatile organic matter in the exhaust gas. After long-term use, the mounting plate 6 is pulled out by the handle, and the mounting plate 6 cooperates with the limiting slider 23 to be pulled out along the limiting slide groove 25, so as to replace the activated carbon net 12 after long-term use to ensure the subsequent adsorption effect;

[0037] Step 2: When the exhaust gas is subjected to oxidation reaction treatment, the first motor 14 is started to drive the rotating shaft 19 to rotate, thereby driving the eccentric block 21 to rotate. The rotation of the eccentric block 21 drives the connecting rod 22 to swing. The connecting rod 22 cooperates with the spring 20 to drive the screen 13 to form a vibrating screen effect, thereby screening out the catalyst, which is of similar size and easy to burn;

[0038] Then, the second motor 16 is started to drive the feed chamber 17 to rotate. According to the total amount of exhaust gas, the rotation time and speed of the second motor 16 are controlled, thereby controlling the amount of catalyst fed. The catalyst falls onto the upper surface of the heating net 8, and the combustion bed 9 is started to heat the catalyst on the upper surface of the heating net 8. When the exhaust gas enters the oxidation treatment chamber 10, the exhaust gas is oxidized.

[0039] In summary, the exhaust gas enters the solvent box 5 through the air inlet 7. The exhaust gas dissolved and absorbed by the solvent floats up and passes through the activated carbon net 12. The activated carbon net 12 adsorbs the odor and volatile organic matter in the exhaust gas. The exhaust gas after double treatment enters the oxidation treatment chamber 10. At this time, the quantitative feeding mechanism 3 is used to control the catalyst feeding amount according to the total amount of exhaust gas. The catalyst is heated by the combustion bed 9 to form a sufficient oxidation reaction to ensure the treatment effect of the exhaust gas.

[0040] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
