Description

Technical Field

[0001] This utility model relates to the field of waste gas purification technology, specifically a VOCs waste gas purification tower. Background Technology

[0002] Industrial enterprises emit exhaust gases containing hydrocarbons during production, storage, and loading / unloading processes, causing serious environmental pollution, wasting valuable resources, and increasing factory costs. Effective recycling or treatment of these gases is necessary. The main technical challenges include uncertain composition and concentration of the exhaust gas, significant variations in treatment volume, low concentrations of substances to be treated, low pressure, and significant influence from external factors. Mature industrial technologies include adsorption, absorption, washing, condensation, membrane technology, photodegradation, chemical reactions (catalytic combustion), plasma degradation, and biological separation. Depending on the specific operating conditions, one or more methods may be used to separate organic matter from the exhaust gas.

[0003] A search revealed Chinese Patent Publication No. CN112691500A, which discloses an industrial VOCs waste gas purification tower. The tower includes a tower body with multiple vertically spaced horizontal partitions inside. An activated carbon adsorption box is positioned between any two adjacent partitions, with its upper and lower ends abutting against the two partitions respectively. Through holes on any two adjacent partitions are located on either side of the activated carbon adsorption box between those partitions. An air inlet is located below the partitions on the tower body, and a drain outlet is located at its bottom. An air outlet and a water inlet pipe are located at the top of the tower body. The waste gas is sequentially adsorbed and filtered by the multiple activated carbon adsorption boxes and then discharged from the tower body through the air outlet. When the activated carbon is saturated, the air inlet is closed and the drain outlet is opened, allowing water to flow through the water inlet pipe. The water washes over the partitions and activated carbon adsorption boxes, thereby desorbing dust and impurities from the activated carbon surface. The resulting wastewater is discharged through the drain outlet.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following shortcomings: First, the accuracy and real-time performance of temperature monitoring are insufficient, and the internal temperature status of the equipment cannot be accurately reflected by existing monitoring mechanisms. When the equipment is in complex working conditions with high temperature, high humidity, high dust, or strong corrosion, the existing protective design is difficult to effectively resist the erosion of environmental factors. Its large size limits its deployment flexibility in confined working environments, and the equipment installation and maintenance costs are high. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0024] This application discloses a VOCs waste gas purification tower. Please refer to... Figure 1 , Figure 3 The system includes: a purification tower body 1, the outer side of which is wrapped with heat-insulating material; an assembly chamber 11 is provided on the front side of the purification tower body 1; a reaction chamber 12 is fixedly installed inside the assembly chamber 11; an air inlet pipe 13 is fixedly installed on the left side of the reaction chamber 12; the air inlet pipe 13 is connected to the reaction chamber 12 and extends out of the purification tower body 1; an exhaust pipe 14 is fixedly installed at the bottom of the reaction chamber 12; the exhaust pipe 14 is connected to the reaction chamber 12 and extends out of the purification tower body 1; a first monitor 15 is fixedly installed at the top of the reaction chamber 12; and a second monitor 16 is sleeved on the exhaust pipe 14.

[0025] With the above technical solution, during operation, VOCs exhaust gas can be introduced through the intake pipe 13 to react with the catalyst inside the reaction chamber 12. The purified gas is discharged through the exhaust pipe 14. The first monitor 15 can monitor the temperature of the reaction chamber 12 in real time, and the second monitor 16 is used to monitor the temperature of the exhaust pipe 14 to ensure that the equipment temperature is within the safe threshold.

[0026] See Figure 2 , Figure 4A sealing door 2 is hinged to the front of the purification tower body 1. The sealing door 2 is used to isolate the assembly chamber 11. A handle 21 is fixedly installed on the front of the sealing door 2. A magnetic strip 22 is fixedly installed at the position where the sealing door 2 fits against the front of the purification tower body 1. A reinforcing plate 23 is fixedly installed on the inner wall of the assembly chamber 11. A locking knob 24 is rotatably installed on the front of the purification tower body 1. The locking knob 24 is used to restrict the sealing door 2.

[0027] With the above technical solution, during operation, the operator can pull the sealing door 2 by holding the handle 21, so that it can rotate around the hinge to open or close. When the sealing door 2 is closed, the magnetic strip 22 can attract the sealing door 2 to enhance the sealing performance. After the sealing door 2 is closed, the operator can turn the locking knob 24 to lock it to prevent accidental opening, so that the reaction chamber 12 is in a closed environment to ensure the safety of personnel during the purification process. To open, simply turn the knob in the opposite direction.

[0028] See Figure 1 , Figure 2 , Figure 3 A fixing groove 3 is provided at the bottom front side of the main body 1 of the purification tower. A dustproof net 31 is locked inside the fixing groove 3 by screws. An exhaust fan 32 is sleeved on the exhaust pipe 14. The exhaust outlet of the exhaust fan 32 is connected to the exhaust pipe 14. The air inlet of the exhaust fan 32 is connected to the fixing groove 3 on one side. A base 4 is fixedly installed at the four corners of the bottom of the main body 1 of the purification tower.

[0029] Through the above technical solution, the purified gas is extracted by the induced draft fan 32. When it is necessary to clean or replace the dust screen 31, the operator can unscrew the screws to remove it, and then tighten the screws to fix it after the operation is completed. During installation, the purification tower body 1 can be placed stably in the designated position through the base 4.

[0030] See Figure 3 The reaction chamber 12 is equipped with multiple sets of reaction beds 5, and a partition plate 51 is fixedly installed between the reaction beds 5. The partition plate 51 is used to divide the reaction chamber 12 into multiple areas. A sealing cover plate 52 is screwed on the front side of the reaction chamber 12.

[0031] Through the above technical solution, corresponding purification materials can be placed in each area according to different purification needs. When it is necessary to replace the purification materials in the reaction bed 5 or to maintain the inside of the reaction chamber 12, the operator can unscrew the screws to open the sealing cover 52. After the operation is completed, the sealing cover 52 is locked with screws. The partition plate 51 divides the inside of the reaction chamber 12 into multiple areas. The opening of the partition plate 51 is relatively narrow, which prolongs the reaction time between the exhaust gas and the catalyst in the reaction bed 5 and improves the purification effect.

[0032] See Figure 2The purification tower body 1 has an installation groove 6 on the front side, and a controller 61 is fixedly installed inside the installation groove 6. A protective cover 62 is hinged to the opening of the installation groove 6 through a damping pivot. A warning light 63 is fixedly installed at the top of the purification tower body 1. The controller 61 is connected to the warning light 63, the first monitor 15, the second monitor 16, and the induced draft fan 32. The controller 61 is used to collect data from the first monitor 15 and the second monitor 16, and to control the induced draft fan 32. The warning light 63 is used to issue an alarm when the data from the first monitor 15 and the second monitor 16 is abnormal.

[0033] Through the above technical solution, the operator can perform parameter setting, data query and other operations through the operation buttons on the controller 61. When the controller 61 is not operated, the protective cover 62 can be rotated to cover the opening of the mounting slot 6 to protect the controller 61. When operating, it can be opened by rotating it in the opposite direction. The working parameters of the induced draft fan 32 can be preset through the controller 61 to achieve automatic control. When the first monitor 15 and the second monitor 16 generate abnormal data, the warning light 63 will start to flash. After the operator sees the warning light 63 alarm, he / she can check and deal with it in time.

[0034] See Figure 5 A heat insulation sleeve 7 is fitted onto the exhaust pipe 14. A heat-conducting copper pipe 71 is spirally wound inside the heat insulation sleeve 7. A water inlet connection pipe 72 is fixedly installed at the upper opening of the heat-conducting copper pipe 71, and a water outlet connection pipe 73 is fixedly installed at the lower opening of the heat-conducting copper pipe 71. The water inlet connection pipe 72 and the water outlet connection pipe 73 are connected to the heat-conducting copper pipe 71 and extend out of the purification tower body 1.

[0035] With the above technical solution, during operation, the inlet water connection pipe 72 can be connected to an external cooling water source, and the outlet water connection pipe 73 can be connected to a return water pipe. The cooling water flow rate can be controlled by adjusting the inlet water valve to achieve a good cooling effect and avoid the adverse effects caused by high-temperature gas emissions.

[0036] Its working principle is as follows: VOCs waste gas is introduced through the intake pipe 13 and reacts with the catalyst inside the reaction chamber 12. The purified gas is discharged through the exhaust pipe 14 via the exhaust fan 32. The first monitor 15 can monitor the temperature of the reaction chamber 12 in real time, and the second monitor 16 is used to monitor the temperature of the exhaust pipe 14 to ensure that the equipment temperature is within the safe threshold. The operator can pull the sealing door 2 by holding the handle 21 and rotating it around the hinge to open or close it. When the sealing door 2 is closed, the magnetic strip 22 can attract the sealing door 2 to enhance the sealing. After the sealing door 2 is closed, the operator can turn the locking knob 24 to lock it to prevent accidental opening. To open it, simply turn it in the opposite direction. Appropriate purification materials can be placed in each area according to different purification needs. When it is necessary to replace the purification materials in the reaction bed 5 or to perform maintenance on the inside of the reaction chamber 12, the operator can unscrew the screws to open the sealing cover 52. After the operation is completed, the sealing cover 52 can be closed again. The partition plate 51, secured with screws, divides the interior of the reaction chamber 12 into multiple zones. The narrow opening of the partition plate 51 extends the reaction time between the exhaust gas and the catalyst in the reaction bed 5, improving the purification effect. Operators can set parameters and query data using the operation buttons on the controller 61. When not operating the controller 61, the protective cover 62 can be rotated to cover the opening of the mounting slot 6, protecting the controller 61. Reverse rotation opens the cover during operation. The operating parameters of the induced draft fan 32 can be preset via the controller 61 for automatic control. When the first monitor 15 and the second monitor 16 generate abnormal data, the warning light 63 starts flashing. After seeing the warning light 63, operators can promptly check and handle the situation. The inlet water connection pipe 72 can be connected to an external cooling water source, and the outlet water connection pipe 73 can be connected to a return water pipe. The cooling water flow rate can be controlled by adjusting the inlet water valve to achieve a good cooling effect and avoid adverse effects caused by high-temperature gas emissions.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
