Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas catalytic combustion, and particularly relates to a waste gas catalytic combustion device. Background Technique

[0002] The waste gas catalytic combustion technology has the advantages of high treatment efficiency, low energy consumption, and small secondary pollution, and is widely used in the treatment of organic waste gas in industries such as chemical industry, printing, painting, and electronics.

[0003] For example, a Chinese patent with the publication number CN217785158U discloses a waste gas catalytic combustion device, which includes a combustion chamber body. Universal wheels are rotatably connected to the four corners at the bottom of the combustion chamber body through wheel frames. The combustion chamber body is integrally formed and communicated with an air inlet. A bottom plate is fixedly installed at the bottom of one side of the combustion chamber body. A blower is fixedly installed on the outer side of the top of the bottom plate, and an air supply pipe is communicated with the top of the blower. In the utility model, by providing a vibration sensor and a push rod motor, whenever the staff turns on the switch of the blower to operate, the vibration sensor detects the vibration intensity, the processor receives the data and issues an instruction, and the push rod motor drives the heat insulation plate to move upward so that the through hole is aligned with the air supply pipe. When the combustion chamber body and the blower are closed, the push rod motor drives the heat insulation plate to move downward to separate the air inlet and the air supply pipe, so as to block the heat dissipated through the air inlet and avoid the blower from being damaged by heat, playing a protective role.

[0004] The above patent has the following problems:

[0005] When the above patent is in use, there are some disadvantages, such as: when the combustion chamber body of this device is used for a long time, a large amount of heat will be generated, resulting in the combustion chamber body being in a high-temperature state for a long time, which easily causes the combustion chamber body to be damaged and reduces the service life of the combustion chamber body. In addition, when catalytically combusting waste gas, particulate residues will be generated, and the particulate residues will remain in the combustion chamber body, which is not convenient for personnel to clean. In view of this, we propose a waste gas catalytic combustion device. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a waste gas catalytic combustion device to solve the problems put forward in the above background technique.

[0007] In view of this, the utility model provides a waste gas catalytic combustion device, including:

[0009] Power assembly, the power assembly is located on the combustion chamber body and is used to drive the two fan blades to rotate;

[0010] Collection box, the collection box is slidably installed at the bottom of the combustion chamber;

[0011] Limiting assembly, the limiting assembly is located inside the combustion chamber body and is used to limit the collection box.

[0012] In this technical solution, by setting the power assembly, driving the power assembly, the power assembly drives the two fan blades to rotate. At the same time, the water pump is started. The water pump can pump out the coolant in the copper pipe and transport it into the annular pipe. Subsequently, the coolant will flow upward in the annular pipe and then flow into the connecting pipe. At the same time, the coolant will take out the heat generated by combustion in the combustion chamber. Subsequently, the coolant in the connecting pipe will flow into the copper pipe. The rotation of the two fan blades can blow the air into the rectangular groove through a plurality of ventilation holes on one side of the protective cover. After that, the air in the rectangular groove can discharge the heat dissipated by the copper pipe through a plurality of ventilation holes on the other side of the protective cover, so as to achieve the effect of cooling the copper pipe and the coolant inside the copper pipe. The cooled coolant will be pumped out by the water pump again and transported into the annular pipe, so as to achieve the effect of circulating cooling the combustion chamber, ensuring that the temperature in the combustion chamber will not be too high, thereby prolonging the service life of the overall device;

[0013] Through the set limiting assembly, the limiting assembly can release the limit on the collection box. At this time, the collection box can be pulled out and the particulate residue in the collection box can be collected and processed. After the processing is completed, the personnel can insert the collection box into the combustion chamber again. When the collection box completely enters the combustion chamber, the limiting assembly can limit the collection box to ensure that the collection box will not be pulled out, ensuring that it is convenient for personnel to collect and clean the particulate residue generated by combustion.

[0014] In the above technical solution, further, the power assembly includes:

[0015] A cylinder is fixedly installed on one side of the combustion chamber body. On the sides of the two fan blades away from the protective cover, a second transmission wheel and a first transmission wheel are respectively fixedly installed. A belt is installed between the second transmission wheel and the first transmission wheel for transmission. One end of the cylinder is fixedly installed with a motor, and the output end of the motor is coaxially connected to the second transmission wheel.

[0016] In this technical solution, when the motor is started, the output shaft of the motor rotates to drive the second transmission wheel to rotate. The second transmission wheel rotates to drive the belt for transmission. Under the action of the belt transmission, the belt drives the first transmission wheel to rotate. The rotation of the second transmission wheel and the first transmission wheel will respectively drive the two fan blades to rotate. The rotation of the two fan blades can blow the wind into the rectangular groove through a number of ventilation holes on one side of the protective cover. Then, the wind in the rectangular groove can discharge the heat dissipated by the copper pipe through a number of ventilation holes on the other side of the protective cover, so as to achieve the effect of cooling the copper pipe and the coolant inside the copper pipe. After cooling, the coolant will be pumped out by the water pump and transported to the annular pipe, so as to achieve the effect of circulating cooling of the combustion chamber, ensuring that the temperature in the combustion chamber will not be too high, and thus extending the service life of the overall device.

[0017] In the above technical solution, further, the limiting component includes:

[0018] A sliding groove is opened in the combustion chamber body and is located on one side of the collection box. A spring block is slidably installed in the sliding groove. One end of the spring block penetrates through one side of the sliding groove and extends into the collection box. The other end of the spring block is fixedly installed with a pull rod. One end of the pull rod penetrates through the other side of the sliding groove and extends to the outside. A spring is sleeved on the pull rod and is located in the sliding groove.

[0019] In this technical solution, when the pull rod is pulled outwards, the pull rod drives the spring block to move in the sliding groove. The movement of the spring block will squeeze the spring to contract. When one end of the spring block moves out of the collection box, the spring block can release the limit on the collection box. At this time, the collection box can be pulled out, and the particulate residue in the collection box can be collected and processed. After the processing is completed, the personnel can insert the collection box into the combustion chamber again. When the collection box completely enters the combustion chamber, under the action of the spring's rebound force, the spring will squeeze the spring block, so that one end of the spring block inserts into the collection box. At this time, the spring block can limit the collection box to ensure that the collection box will not be pulled out, ensuring that it is convenient for personnel to collect and clean the particulate residue generated by combustion.

[0020] In the above technical solution, further, the spring block is slidably connected to the combustion chamber body. One end of the spring block is in plug-in fit with the collection box. The pull rod is slidably connected to the sliding groove and the combustion chamber body. The two ends of the spring are tightly welded to the spring block and the inner wall of the sliding groove respectively.

[0021] In this technical solution, ensure that one end of the elastic block can slide normally within the combustion chamber body, ensure that one end of the elastic block can be inserted into the collection box, ensure that the pull rod can slide normally within the sliding groove and the combustion chamber body, and ensure the structural stability of the spring.

[0025] In this technical solution, during use, first discharge the waste gas to be catalytically combusted into the combustion chamber from the feed pipe. At the same time, oxygen will enter the combustion chamber through the air inlet pipe, and the waste gas will burn in the combustion chamber. When the catalytic combustion of the waste gas is completed, the combusted waste gas will be discharged to the outside through the air outlet pipe. At the same time, under the filtering action of the filter screen, the residues generated during the combustion in the combustion chamber will not be discharged to the outside.

[0068] When the catalytic combustion of the waste gas is completed, the combusted waste gas will be discharged to the outside through the outlet pipe. At the same time, under the action of the filtration of the filter screen, the residues generated during the combustion in the combustion chamber 2 will not be discharged to the outside. The particulate residues generated during the combustion process will fall into the collection box 17 under the action of gravity. The personnel can first pull the pull rod 20 outwards. The pull rod 20 drives the elastic block 19 to move in the sliding groove 18. The movement of the elastic block 19 will squeeze the spring 21 to contract. When one end of the elastic block 19 moves out of the collection box 17, the elastic block 19 can release the limit on the collection box 17. At this time, the collection box 17 can be pulled out, and the particulate residues in the collection box 17 can be collected and processed. After the processing is completed, the personnel can insert the collection box 17 into the combustion chamber 2 again. When the collection box 17 completely enters the combustion chamber 2, under the action of the rebounding force of the spring 21, the spring 21 will squeeze the elastic block 19, so that one end of the elastic block 19 inserts into the collection box 17. At this time, the elastic block 19 can limit the collection box 17 to ensure that the collection box 17 will not be pulled out, and ensure that it is convenient for the personnel to collect and clean the particulate residues generated by the combustion.
