Description

Technical Field

[0001] The present application specifically relates to a chemical sulfide waste gas purification treatment equipment, belonging to the technical field of waste gas treatment. Background Art

[0002] In the prior art, activated carbon is usually used as an adsorption material in the form of rods or powders in gas purification systems. Due to the limitations of its geometric shape, rod-shaped activated carbon can only use the outer surface to effectively contact the flowing gas, while the internal core area is difficult to achieve sufficient contact and adsorption due to the limited gas flow path, resulting in low and incomplete adsorption efficiency. For powdered activated carbon, in order to avoid its loss in the airflow and the secondary pollution problems caused by it, it is usually necessary to compact it before use. However, this compaction treatment method significantly reduces the gas permeability, so that the effective adsorption is mainly limited to the surface part, thereby greatly limiting the adsorption capacity.

[0003] In addition, when the activated carbon reaches the adsorption saturation state, it needs to be replaced as a whole, which not only increases the operating cost, but also causes a waste of resources. In view of the above limitations, it is urgent to develop a new sulfide waste gas purification treatment device that can improve the adsorption efficiency, make full use of the adsorption capacity of activated carbon, and is more economical and efficient. By optimizing the morphological structure of activated carbon and its arrangement in the filter, the contact efficiency between the gas and the activated carbon can be significantly improved, thereby enhancing the removal effect of harmful gases such as sulfides, while reducing operating costs.

DETAILED DESCRIPTION

[0019] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0021] Refer to the following Figures 1 to 16 The invention describes a chemical sulfide waste gas purification treatment device provided according to some embodiments of the present application.

[0022] In some embodiments, please refer to Figures 1 and Figure 2 The chemical sulfide waste gas purification treatment equipment includes: a shell 100, which is provided with an air inlet 110 and an exhaust port 120; an air inlet plate 200, which is arranged inside the shell 100, and an air inlet 220 is provided on the air inlet plate 200; a plurality of partition plates 300, which are spaced above the air inlet plate 200, and a filter chamber is provided between the air inlet plate 200, the plurality of partition plates 300 and the shell 100; activated carbon particles are distributed in the filter chamber; an air flow driving component 400, which is installed on the shell 100, guides the exhaust gas to enter the filter chamber from the air inlet 110, and is discharged through the exhaust port 120 after interacting with the activated carbon particles; a first separation box 500, which is connected to the exhaust port 120, and is used for preliminarily collecting the activated carbon particles in the exhaust gas; a second separation box 600, which is connected to the first separation box 500, and is used for filtering and finally collecting the activated carbon particles in the exhaust gas; a reflux component 700, and the inlet of the reflux component 700 is connected to the second separation box 600. The outlet is connected to the housing 100 for returning the activated carbon particles to the filter chamber under pressure.

[0023] In this embodiment, the exhaust gas enters from the air inlet 110 of the housing 100, and is evenly diffused into the filter chamber through the air inlet 220 of the air inlet plate 200, and is fully contacted with the activated carbon particles distributed therein. In this process, the activated carbon particles are blown up by the exhaust gas to a certain extent and evenly and dynamically dispersed in the filter chamber to contact the exhaust gas to the greatest extent. Then, the exhaust gas forms a turbulent mixture with the partially dispersed activated carbon particles under the action of the spiral guide blades 420 of the air flow drive component 400, and is output from the exhaust port 120 and enters the first separation box 500, where the activated carbon particles carried are initially separated by gravity sedimentation; the remaining dust-containing gas enters the second separation box 600, and the residual particles are filtered out by the bag filter 610 and the clean gas is discharged; among the separated activated carbon particles, the adsorption-saturated heavy particles are deposited in the first separation box 500, and the unsaturated light particles are deposited to the bottom in the second separation box 600, and then discharged by the reflux component 700. The waste gas is sent back to the filter chamber for recycling. The waste gas is usually pre-treated by drying.

[0024] In some embodiments, see Figure 3 and Figure 4 The air inlet disk 200 includes: a mounting plate 210, which is arranged on the shell 100, and has a plurality of air inlets 220 on the mounting plate 210; a plurality of one-way valves 230, which correspond to the plurality of air inlets 220 one by one and are arranged on the mounting plate 210, and the plurality of one-way valves 230 are used to limit the exhaust gas from flowing back to the side of the air inlet disk 200 away from the partition plate 300.

[0025] In this embodiment, when the exhaust gas passes through the air inlet 220, the one-way valve 230 is pushed to open. When the airflow stops, the one-way valve 230 automatically closes under the action of its own weight and the reset of the one-way valve spring 234, effectively preventing the activated carbon particles from flowing back into the air inlet channel. The mounting plate 210 realizes laminar distribution of the airflow by evenly distributing the air inlet 220, so that the airflow contacts the activated carbon particles in the filter chamber more evenly.

[0026] In some embodiments, see Figure 5 , Figure 6 and Figure 7 The one-way valve 230 includes: a one-way valve body 231, which is vertically installed on the mounting plate 210; an isolation cap 232, which is arranged on the top of the one-way valve body 231; an air intake sliding tube 233, which is slidably sleeved in the one-way valve body 231, and a vent hole is provided on its wall, and the diameter of the top closed end is larger than the outer diameter of the one-way valve body 231; a one-way valve spring 234, which connects the top of the air intake sliding tube 233 and the inner wall of the isolation cap 232.

[0027] In this embodiment, the exhaust gas pressure acts from bottom to top, pushing the air intake sliding pipe 233 to move upward, and at the same time, the one-way valve spring 234 is compressed. As the air intake sliding pipe 233 moves upward, the vent hole on its wall gradually moves upward beyond the top of the one-way valve column 231, and the air flow can overflow from the vent hole. The isolation cap 232 disposed on the top of the one-way valve column 231, on the one hand, will resist the air intake sliding pipe 233 to limit its excessive upward movement, and on the other hand, it can guide the overflowing gas to flow to the side of the mounting plate 210 away from the plurality of partition plates 300. When the air flow weakens, the one-way valve spring 234 begins to reset, pushing the air intake sliding pipe 233 down, until the vent hole overlaps with the inner wall of the one-way valve column 231 again, thereby closing the channel and effectively blocking the reverse air flow. In addition, the isolation cap 232 can also effectively prevent the activated carbon particles in the filter chamber from entering the air outlet pipe to avoid blockage.

[0028] In some embodiments, see Figure 8 and Fig. 9 The airflow driving assembly 400 includes: an air inlet fan 410, which is installed on the bottom side wall of the shell 100 and is connected to the air inlet plate 200 to provide a penetrating airflow from bottom to top; a spiral guide blade 420, which is installed above a plurality of partition plates 300 and is used to form a swirl flow of the exhaust gas and then discharge it from the exhaust port 120; a swirl motor 430, which is installed on the top of the shell 100, and its output shaft is coaxially connected to the spiral guide blade 420 to drive the blade to rotate.

[0029] In this embodiment, the air inlet fan 410 is installed on the bottom side wall of the housing 100. When the air inlet fan 410 starts to operate, it will continuously transport exhaust gas into the housing 100. The exhaust gas passes through the filter chamber from bottom to top and then flows to the top of the chamber. At this time, the swirl motor 430 drives the spiral guide blade 420 to rotate continuously. Under the action of the spiral guide blade 420, the dust-containing exhaust gas after preliminary filtration is laterally guided to the exhaust port 120 opened on the top side wall of the housing 100, and then enters the first separation box 500.

[0030] In some embodiments, please refer to Figure 8 and Fig. 9 A downwardly recessed conical bucket is also provided between the spiral guide blades 420 and the plurality of partition plates 300 to isolate the blades from a large amount of activated carbon particles.

[0031] In some embodiments, see Fig.10 The second separation box 600 includes: a bag filter 610 installed inside the second separation box 600, used to filter the residual activated carbon particles in the exhaust gas and output the purified gas.

[0032] In this embodiment, the shell of the bag filter 610 is embedded in the top of the second separation box 600.

[0033] In some embodiments, see Fig.11 The bag filter 610 includes: an inner plate 611, which is horizontally arranged inside the bag filter 610 shell; a filter bag 612, and a plurality of filter bags 612 are sequentially arranged below the inner plate 611 at intervals; a gas outlet 613, which is arranged at the top of the bag filter 610 shell and communicated with the openings of all the filter bags 612.

[0034] In this embodiment, the size of the filter bag 612 varies according to the space in which the filter bag 612 is distributed in the second separation box 600. In some embodiments, see Fig.12 , Fig.13 , Fig.14 , Fig.15 and Fig.16 The reflux assembly 700 includes: a reflux pressure pump 710; a reflux motor 720, which is arranged at the bottom of the second separation box 600; a reflux slot column 730, which is connected to the reflux motor 720; an arc-shaped paddle group 740, which includes a plurality of arc-shaped paddles 741 distributed along a spiral trajectory, and whose rotating shaft is coaxially connected to the output shaft of the reflux motor 720; the arc-shaped paddle group 740 is rotatably connected to the bottom end of the reflux pressure pump 710 to drive the operation of the reflux pressure pump 710; an injection pipe 750, one end of which is connected to the outlet of the reflux pressure pump 710, and the other end extends to the bottom chamber of the second separation box 600; a one-way injection valve is provided at the end connected to the outlet of the reflux pressure pump 710; a reflux pipe 760, which connects the bottom of the second separation box 600 and the shell 100.

[0035] In this embodiment, the activated carbon particles are deposited from the second separation box 600 to the reflux trough column 730 at the bottom. The reflux trough column 730 is a cylinder with two grooves on the column wall. The center of the reflux trough column 730 is coaxial with the output shaft of the reflux motor 720. During the operation of the reflux motor 720, the reflux trough column 730 and the arc-shaped paddle group 740 rotate under the action of the reflux motor 720. The activated carbon particles falling into the grooves of the reflux trough column 730 are transported downward to the bottom in batches along with the rotation. The arc-shaped paddle group 740 provides power to the reflux pressure pump 710 during the rotation. The reflux pressure pump 710 presses out the gas and sprays it out from the jet pipe 750. A one-way jet valve is provided at the connection between the jet pipe 750 and the reflux pressure pump 710 to prevent gas backflow. The other end of the jet pipe 750 is connected to the second separation box 600. The bottom, which is also below the reflux groove and at the end of the reflux pipe 760, the ejected gas can better drive the deposited activated carbon particles into the reflux pipe 760 and finally be recovered into the filter chamber.

[0036] In some embodiments, please refer to Fig.13 , Fig.14 and Fig.15 The reflux pressure pump 710 includes: a piston 711; a lever frame 712, one end of which is connected to the bottom of the piston 711 and the other end of which is against the inner arc side of the arc-shaped lever 741; and a reflux spring 713, which is arranged in the compressible space formed by the top of the piston 711 and the top of the reflux pressure pump 710.

[0037] In this embodiment, in the reflux pressure pump 710, the top of the piston 711 and the top of the pump form a compressible space, in which a reflux spring 713 is provided, and one end of the paddle frame 712 is connected to the bottom of the piston 711, and the other end is against the inner arc side of the arc-shaped paddle 741. When the arc-shaped paddle 741 rotates clockwise, the paddle frame 712 against its inner arc side is lifted upward, driving the piston 711 to move upward and compressing the reflux spring 713; when the paddle frame 712 runs to the edge of the arc-shaped paddle 741, it naturally loosens and falls downward, and the reflux spring 713 restores its length, pushing the piston 711 downward, compressing the gas in the gas storage space formed by the piston 711 and the shell of the reflux pressure pump 710 to the injection pipe 750. Preferably, the contact end of the paddle frame 712 and the arc-shaped paddle 714 is provided with a roller to facilitate the rolling of the paddle frame 712 on the inner arc of the arc-shaped paddle 714.

[0038] In some embodiments, please refer to Figure 4 , a plurality of ventilation holes 310 are distributed on the plurality of partition plates 300 .

[0039] In this embodiment, the ventilation holes 310 can disperse the flow direction of the airflow, improve the air permeability of the filter chamber, and make the exhaust gas contact with the activated carbon particles more fully, thereby improving the adsorption efficiency.

[0040] In some embodiments, please refer to Fig.10 The cross-sections of the first separation box 500 and the second separation box 600 are tapered trapezoidal structures, which are used to accelerate the sedimentation of activated carbon particles.

[0041] In this embodiment, the dust-containing exhaust gas after preliminary filtration is laterally guided to the exhaust port 120 opened on the top side wall of the shell 100 under the action of the spiral guide blades 420, and then enters the first separation box 500 and the second separation box 600. During the ejection process, the carbon dust in the exhaust gas falls into different separation boxes due to different weights. The fully adsorbed carbon dust has a larger mass and thus falls into the first separation box 500. The accumulated carbon dust is then discharged from the bottom of the first separation box 500 through the motor and slot column consistent with the bottom device of the second separation box 600, while the incompletely adsorbed carbon dust has a smaller mass and falls into the second separation box 600, and is transported back to the filter chamber through the reflux pipe 760 for reuse.

[0042] In some embodiments, see Fig.10 , and also includes a bracket supporting the first separation box 500 and the second separation box 600.
