Description

Technical Field

[0001] This utility model belongs to the field of waste gas filtration technology, and in particular relates to a filter press exhaust gas collection and treatment device. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to a material, causing the liquid to permeate out. It is a commonly used solid-liquid separation device, widely used in industries such as chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramics, and environmental protection. Filter presses typically use compressed air for filtration, but the continuous contact between the compressed air and the liquid passing through the press can lead to contamination of the gas by harmful substances in the liquid, preventing direct release into the environment. Exhaust gas must be purified using exhaust gas collection and treatment equipment to ensure compliance with emission standards. However, in practical use, it still has the following drawbacks:

[0003] The utility model disclosed in CN212915146U is a pollution-free emission device for filter press exhaust gas. The inner cavity of the tower is provided with an acid washing chamber, an alkaline washing chamber, and a water washing chamber from bottom to top. An air inlet is provided on one side of the acid washing chamber, and the air inlet is connected to a first L-shaped pipe. A first air guide pipe is connected between the acid washing chamber and the alkaline washing chamber, and the first air guide pipe is connected to a second L-shaped pipe. A second air guide pipe is connected between the alkaline washing chamber and the water washing chamber. A spray assembly is provided near the top of the inner cavity of the water washing chamber, and an activated carbon adsorption assembly is provided at the top of the water washing chamber. An exhaust fan is provided above the activated carbon adsorption assembly, and an exhaust port is provided above the exhaust fan and at the top of the tower. Since the filter press uses a large amount of compressed air, in order to ensure that the exhaust gas is fully treated in the treatment equipment, it is usually necessary to increase the volume of the equipment to extend the treatment time of the exhaust gas. As a result, the equipment is usually large in size, which is not convenient to move and occupies a lot of space, making it inconvenient to arrange the space.

[0004] When waste gas enters the treatment equipment for treatment, it often needs to be acid-washed and alkaline-washed. After treatment with one type of treatment agent, the flowing waste gas often contains a certain amount of the treatment agent. When the waste gas is treated with another type of treatment agent, the two treatment agents may react with each other, reducing the treatment efficiency of the other type of treatment agent on the waste gas, and thus reducing the overall treatment efficiency of the waste gas. Utility Model Content

[0005] The purpose of this utility model is to provide a filter press exhaust gas collection and treatment device. By moving the water tank, the first purification pipe and the second purification pipe, it solves the problem that filter press exhaust gas collection and treatment devices need to treat a large amount of waste gas. In order to ensure treatment efficiency, the device is usually large in size, occupies a lot of space and is not easy to move. After the waste gas is treated by one type of treatment agent, when the waste gas containing one type of treatment agent is mixed with another type of treatment agent, the reaction between the two treatment agents will reduce the treatment efficiency of the other treatment agent.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a filter press exhaust gas collection and treatment device, comprising a mobile water tank, a first purification pipe, and a second purification pipe. The device is characterized in that: a universal wheel is rotatably engaged at the bottom of the mobile water tank; a ventilation support box is welded through the top of the mobile water tank; the first purification pipe is slidably engaged at the top of the outer periphery of the ventilation support box; a first lifting cylinder is provided at both ends of the bottom of the first purification pipe; a first flexible connecting pipe is provided at the bottom of the outer periphery of the first purification pipe; a first semiconductor refrigeration component is engaged at the outer periphery of the first flexible connecting pipe; a second purification pipe is slidably engaged at the top of the outer periphery of the first purification pipe; a second lifting cylinder is provided at both ends of the bottom of the second purification pipe; a second flexible connecting pipe is provided at the bottom of the second purification pipe; and a second semiconductor refrigeration component is engaged at the outer periphery of the second flexible connecting pipe.

[0008] When the exhaust gas enters the mobile water tank, the liquid inside filters out particulate matter. The casters allow for easy movement of the equipment, improving its usability. The mobile water tank can hold a large amount of liquid to lower the equipment's center of gravity and ensure stability. After filtration, the exhaust gas enters the first flexible connecting pipe, where a first semiconductor cooling component cools it, causing the water in the exhaust gas to condense and flow back into the mobile water tank, preventing the liquid from affecting purification efficiency. After entering the first purification pipe, the exhaust gas is purified by a treatment agent before entering the second flexible connecting pipe. There, a second semiconductor cooling component cools the exhaust gas, causing the treatment agent in the exhaust gas to condense, preventing the treatment agent from condensing and causing interference between the treatment agent and the sprayed solution in the second purification pipe. A treatment agent reacts to ensure efficient waste gas treatment. The first and second lifting cylinders can move the first and second purification pipes up and down, adjusting the space occupied by the equipment and greatly improving its flexibility during use. This also reduces the probability of damage during movement. Furthermore, because the equipment is telescopic, multiple first purification pipes can be installed between the first and second purification pipes as needed, enabling multi-stage waste gas treatment. This allows for flexible space adjustment while further improving waste gas treatment efficiency. Simultaneously, the equipment can adjust the type of treatment agent in the moving water tank, first purification pipe, and second purification pipe according to the type of treatment agent that will ultimately contact the waste gas, ensuring that the discharged gas meets emission standards. The equipment is flexible and convenient to use.

[0009] Furthermore, an inlet pipe is welded through the top of the outer periphery of the mobile water tank, a drain pipe is welded through the bottom of the outer periphery of the mobile water tank, a filter screen is snapped and fixed inside the mobile water tank, an exhaust pipe is snapped through the top end of the mobile water tank, the bottom of the exhaust pipe is inserted through the top of the filter screen, a first exhaust pipe is welded through the bottom of the outer periphery of the ventilation support box, and a flow guiding and limiting pipe is welded and fixed inside the ventilation support box;

[0010] When the exhaust gas enters the mobile water tank through the extraction pipe, the liquid in the mobile water tank comes into contact with the exhaust gas, and the exhaust gas is further filtered through the filter screen, so that the solid particles in the exhaust gas are retained in the mobile water tank. The universal wheels can move the equipment, improving the convenience of using the equipment. A large amount of liquid can be poured into the mobile water tank to lower the center of gravity of the equipment and ensure its stability.

[0011] Furthermore, each of the first lifting cylinders is slidably connected to the top of a first telescopic tube, the top of the first telescopic tube is connected to the bottom of the first purification tube, the bottom of the first lifting cylinder is connected to the top of the mobile water tank, a first drain pipe, a second exhaust pipe and a first guide pipe are welded through the bottom of the outer periphery of the first purification tube, the second exhaust pipe and the first guide pipe are located at the top of the first drain pipe, the top of the first flexible connecting pipe is connected to one end of the first guide pipe, the bottom of the first flexible connecting pipe is connected to the first drain connecting pipe, a first air inlet connecting pipe is welded through the outer periphery of the first drain connecting pipe, a return solenoid valve is connected through the outer periphery of the first drain connecting pipe, the return solenoid valve is located at the bottom of the first air inlet connecting pipe, one end of the first air inlet connecting pipe is connected to one end of the first exhaust pipe, and the bottom of the first drain connecting pipe is connected through the top of the mobile water tank;

[0012] The first lifting cylinder can drive the extension and retraction of the first telescopic tube, which in turn drives the first purification tube to move up and down, adjusting the space occupied by the equipment, greatly improving the flexibility of the equipment during use, and reducing the probability of damage during the movement of the equipment. When the exhaust gas enters the first flexible connecting tube through the first drain connection pipe, the first semiconductor cooling component can cool the exhaust gas, causing the vaporized liquid in the exhaust gas to condense and flow back to the mobile water tank through the first drain connection pipe, avoiding the liquid from affecting the purification efficiency.

[0013] Furthermore, a first liquid inlet connecting pipe is snapped into the bottom of the first purification pipe, a first spray pipe is snapped into the top of the first liquid inlet connecting pipe, the first spray pipe is snapped into the inner wall of the first purification pipe, a first flow guide is snapped into the top of the first purification pipe, a first flexible limiting pipe is snapped into the bottom of the first flow guide, the bottom of the first flexible limiting pipe is snapped into the top of the ventilation support box, a first flexible air inlet pipe is snapped into the other end of the first flow guide relative to the first flexible connecting pipe, a first air outlet pipe is snapped into the bottom of the first flexible air inlet, the first flow guide is snapped into the outer circumferential surface of the first flexible limiting pipe, and the first air outlet pipe is snapped into the center of the top of the ventilation support box;

[0014] When the exhaust gas enters the first purification pipe, it is guided by the first flexible air inlet pipe and the first flexible limiting pipe, which prolongs the time the exhaust gas spends in the first purification pipe. The treatment agent is sprayed into the first purification pipe through the first spray pipe, so that the exhaust gas and the treatment agent can fully contact and react, thereby purifying the exhaust gas.

[0015] Furthermore, each of the second lifting cylinders is slidably connected to a second telescopic tube at its top, the top of the second telescopic tube is connected to the bottom of the second purification tube, the bottom of the second lifting cylinder is connected to the bottom of the outer circumferential surface of the first purification tube, a second drain pipe, a third exhaust pipe and a second guide pipe are welded through the bottom of the outer circumferential surface of the second purification tube, the top of the second flexible connecting tube is connected to one end of the second guide pipe, the bottom of the second flexible connecting tube is connected to a second drain connecting pipe, a second air inlet connecting pipe is welded through the outer circumferential surface of the second drain connecting pipe, a drain solenoid valve is connected through the outer circumferential surface of the second drain connecting pipe, the drain solenoid valve is located at the bottom of the second air inlet connecting pipe, and one end of the second air inlet connecting pipe is connected to one end of the second exhaust pipe;

[0016] The second lifting cylinder can drive the extension and retraction of the second telescopic tube, further driving the second purification tube to move up and down, adjusting the space occupied by the equipment, greatly improving the flexibility of the equipment during use, and reducing the probability of damage during the movement of the equipment. When the exhaust gas enters the second flexible connecting tube through the second drain connection pipe, the exhaust gas can be cooled by the second semiconductor cooling component, causing the vaporized treatment agent in the exhaust gas to condense and be discharged through the bottom of the second drain connection pipe, avoiding mutual reaction between the two treatment agents and reducing the treatment efficiency of the treatment agent for the exhaust gas.

The treatment agent is sprayed into the second purification pipe through the second spray pipe, so that the exhaust gas and the treatment agent can fully contact and react, thereby purifying the exhaust gas.

[0019] This utility model has the following beneficial effects:

[0020] This invention solves the problem that filter presses typically require a large volume of compressed air to ensure adequate treatment of waste gas, leading to inconvenient movement, space constraints, and poor layout. This is achieved by incorporating a movable water tank, a first purification pipe, and a second purification pipe. The invention utilizes casters for movement and a first and second lifting cylinder to move the first and second purification pipes vertically, adjusting the space occupied and significantly improving operational flexibility. It also reduces the probability of damage during movement. Furthermore, the retractable design allows for the installation of multiple first purification pipes between the first and second purification pipes, enabling multi-stage waste gas treatment. This design further enhances waste gas treatment efficiency while flexibly adjusting space requirements.

[0021] This invention solves the problem that when waste gas enters the treatment equipment, it often requires acid washing and alkali washing. After treatment with one type of treatment agent, the flowing waste gas often contains a certain amount of that agent, which can react with another type of treatment agent, reducing the treatment efficiency of the other agent and consequently lowering the overall waste gas treatment efficiency. When the waste gas enters the first flexible connecting pipe, the first semiconductor cooling component cools it, causing the vaporized liquid in the waste gas to condense and flow back to the mobile water tank through the first drain connecting pipe. After being purified by the second purification pipe and entering the second flexible connecting pipe, the second semiconductor cooling component cools the waste gas, causing the vaporized treatment agent in the waste gas to condense and discharge through the bottom of the second drain connecting pipe. This avoids the mutual reaction between the two treatment agents and ensures the equipment's waste gas treatment efficiency. Attached Figure Description

[0034] Based on the type of exhaust gas generated by the filter press, a treatment device containing an appropriate number of first purification pipes 2 is purchased. A large amount of liquid is poured into the mobile water tank 1. According to the position of the filter press, the device is moved to a suitable position by using casters 101, and the exhaust outlet of the filter press is connected to the extraction pipe 103. According to the environmental control, the height of the first purification pipes 2 and the second purification pipes 3 are further adjusted by the first lifting cylinder 208 and the second lifting cylinder 310.
