Description

Technical Field

[0001] The invention belongs to the technical field of waste gas treatment devices, and in particular relates to a heat storage catalytic oxidation device. Background Art

[0002] Among the methods for treating waste gas, catalytic oxidation is a commonly used method, among which the regenerative catalytic oxidation device is a common catalytic oxidation device. The existing regenerative catalytic oxidation device generally includes a catalytic oxidation device body, in which a heating device, a catalyst chamber, an oxidation reaction chamber and a heat exchanger are arranged. When in use, the organic waste gas is sent into the device body through a pipeline by a fan, and the waste gas is heated to the starting temperature required for catalytic combustion, and then passes through the oxidation reaction chamber and the catalyst chamber, and is catalytically oxidized to finally obtain clean gas. The catalytic oxidation device of this structure has the following technical problems:

[0003] 1. The catalytic chamber and the oxidation chamber are one and are arranged from top to bottom. During the actual intake, the exhaust gas enters from the outside of the catalytic oxidation device, and then diffuses inside and upward. In this way, when the catalytic oxidation device is running upward, there is a difference in the exhaust gas density between the center and the edge of the catalytic oxidation device, resulting in a difference in the exhaust gas concentration between the center and the edge of the catalytic oxidation device. When the treatment effect is used as the benchmark during the treatment process, the exhaust gas treatment efficiency is low.

[0004] 2. Only rely on the pressure relief valve for safety protection. Once the internal pressure of the device is too high, exhaust will be discharged through the pressure relief valve.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Example 1, the present invention provides a thermal storage catalytic oxidation device, see Figure 1, comprising a device body 1, wherein a heating chamber 2, a catalytic chamber, an oxidation reaction chamber, a heat exchange chamber and an air inlet chamber are arranged in the device body, wherein the heating chamber, the catalytic chamber, the oxidation reaction chamber, the heat exchange chamber and the air inlet chamber are all connected, wherein a heating device 3 is arranged in the heating chamber, wherein the heating device is preferably an electric heating device, so as to facilitate automatic control, wherein the catalytic chamber comprises a first catalytic chamber 4 and a second catalytic chamber 5, wherein the oxidation reaction chamber comprises a first oxidation reaction chamber 6 and a second oxidation reaction chamber 7, wherein the heat exchange chamber comprises a first heat exchange chamber 8 and a second heat exchange chamber 9, wherein the air inlet chamber comprises a first air inlet chamber 10 and a second air inlet chamber 11; wherein the first catalytic chamber, the first oxidation reaction chamber, the first heat exchange chamber and the first air inlet chamber are arranged in sequence from top to bottom to form a first reaction matrix, wherein the second catalytic chamber, the second oxidation reaction chamber, the second heat exchange chamber and the second air inlet chamber are arranged in sequence from top to bottom to form a second reaction matrix, wherein the heating chamber is located above the first reaction matrix and the second reaction matrix; and a hollow cavity 12 is formed between the first reaction matrix and the second reaction matrix.

[0026] The above-mentioned regenerative catalytic oxidation device can be used in conjunction with existing devices, see Figure 6 In actual use, an intake valve 103 and an exhaust valve 104 are fixedly arranged on the device body. The intake valve controls the exhaust gas to enter the intake chamber, and the exhaust valve controls the clean gas to be discharged from the device body. The exhaust valve can be arranged at the bottom of the device body or at the top of the device body, which is not specifically limited here. A thermocouple 111 and a pressure transmitter 110 are arranged on the heating chamber to detect the temperature in the heating chamber and adjust the gas pressure in the device body, thereby facilitating automatic control. A thermocouple is also arranged on the oxidation reaction chamber to detect the temperature in the oxidation reaction chamber and thereby facilitating automatic control. Control, it is best to set a pressure relief safety valve 109 on the top of the device body to ensure the safe operation of the equipment. Of course, the air inlet valve is also preferably connected to the flame arrester 102 in sequence to ensure the safe operation of the equipment. The flame arrester is connected to the filter 101 to filter the exhaust gas. The exhaust valve is preferably connected to the manual regulating valve 106 to facilitate manual adjustment of the device. The pressure relief safety valve and the exhaust valve are connected to the expansion joint 107, the induced draft fan 108 and the expansion joint in sequence to finally discharge the purified air. The exhaust valve is also connected to the emergency direct exhaust valve 105 and the cooling valve 112 in sequence to discharge the exhaust gas in an emergency to ensure the safety of the equipment.

[0027] The above-mentioned heat storage catalytic oxidation device divides the catalyst chamber, oxidation reaction chamber, heat exchange chamber and air intake chamber into two groups, and sets the middle position as a cavity, so that the exhaust gas can instantly reach the inner side of the air intake chamber when it enters from the outside of the catalytic oxidation device body and diffuses inward. In this way, when the exhaust gas runs upward, the exhaust gas density difference between the center position and the edge position of the catalytic oxidation device body is greatly reduced, thereby greatly reducing the exhaust gas concentration difference between the center position and the edge position of the catalytic oxidation device body. When the treatment effect is used as the benchmark during the treatment process, the exhaust gas treatment efficiency is relatively high.

[0028] Example 2: Example 2 is a further improvement on Example 1. For details, see Figure 2 and Figure 3 The regenerative catalytic oxidation device comprises a device body 1, wherein a heating chamber 2, a catalytic chamber, an oxidation reaction chamber, a heat exchange chamber and an air inlet chamber are arranged in the device body, wherein the heating chamber, the catalytic chamber, the oxidation reaction chamber, the heat exchange chamber and the air inlet chamber are all connected, wherein a heating device 3 is arranged in the heating chamber, wherein the heating device is preferably an electric heating device, so as to realize automatic control, wherein the catalytic chamber comprises a first catalytic chamber 4 and a second catalytic chamber 5, wherein the oxidation reaction chamber comprises a first oxidation reaction chamber 6 and a second oxidation reaction chamber 7, wherein the heat exchange chamber comprises a first heat exchange chamber 8 and a second heat exchange chamber 9, wherein the air inlet chamber comprises a first air inlet chamber 10 and a second air inlet chamber 11; wherein the first catalytic chamber, the first oxidation reaction chamber, the first heat exchange chamber and the first air inlet chamber are arranged in sequence from top to bottom to form a first reaction matrix, wherein the second catalytic chamber, the second oxidation reaction chamber, the second heat exchange chamber and the second air inlet chamber are arranged in sequence from top to bottom to form a second reaction matrix, and the heating chamber is located above the first reaction matrix and the second reaction matrix; wherein the first A hollow cavity 12 is formed between the reaction substrate and the second reaction substrate; the top of the cavity is connected to the heating chamber; a slider 13 is arranged in the cavity, and the slider is slidably connected and sealed to the cavity; a blocking portion 14 is arranged on the inner wall of the cavity for blocking the slider from sliding upward, and an elastic shielding body is arranged on the slider, the elastic shielding body includes a central tip 15 and an arc-shaped shielding body 16 located on both sides of the tip, one end of the arc-shaped shielding body is connected to the tip, and the other end is connected to the slider, the elastic shielding body is sealed and connected to the slider, and a support chamber is formed between the slider, a plurality of elastic support bodies 17 are arranged in the support chamber, and the support chamber is divided into a plurality of support chamber monomers 18 by the elastic support bodies; an air duct channel 19 is arranged in the slider, and a first connecting channel 20 connected to the support chamber monomer is arranged on one side of the air duct channel, and a second connecting channel 21 connected to the cavity is arranged on the other side.

[0029] When the structure is in use, compressed air is passed through the cavity, wherein the pressure of the compressed air can preferably be set to be adjustable according to actual conditions. When the pressure in the device body exceeds a predetermined value, the pressure in the device body is greater than the pressure in the cavity, and the exhaust gas compression slider in the device body moves downward. At the same time, when the exhaust gas compression elastic shielding body acts on the elastic shielding body, it is squeezed from the tip to the arc-shaped shielding bodies on both sides, exerting a certain pressure on the inner wall of the cavity to offset the pressure on the outer wall of the cavity. When the pressure in the device body exceeds the predetermined value by a large margin, the elastic shielding body can be deformed to form a buffer for the rapidly expanding exhaust gas. In this way, when the internal pressure of the device body has not reached the pressure relief valve to actuate, the pressure of the exhaust gas on the device body can be adjusted, and the staff can be given time for adjustment, which can prevent the exhaust gas pressure from increasing rapidly and being discharged through the pressure relief valve to pollute the environment to a certain extent. When the pressure in the device body is normal and the slider returns to its position, the exhaust gas in the upper part of the cavity can be squeezed into the space in the device body to continue reacting, and there is no need to collect the exhaust gas for further treatment.

wherein the first catalytic chamber, the first oxidation reaction chamber, the first heat exchange chamber and The first air inlet chamber is sequentially arranged from top to bottom to form a first reaction matrix, the second catalytic chamber, the second oxidation reaction chamber, the second heat exchange chamber and the second air inlet chamber are sequentially arranged from top to bottom to form a second reaction matrix, and the heating chamber is located above the first reaction matrix and the second reaction matrix;

a blocking portion 14 for blocking the slider from sliding upward is arranged on the inner wall of the cavity, and an elastic shielding body is arranged on the slider, and the elastic shielding body includes a tip 15 in the middle and a position An arc-shaped shielding body 16 is provided on both sides of the tip, one end of the arc-shaped shielding body is connected to the tip, and the other end is connected to the slider, the elastic shielding body is sealed and connected to the slider, and a support chamber is formed between the elastic shielding body and the slider, a plurality of elastic support bodies 17 are arranged in the support chamber, and the support chamber is divided into a plurality of support chamber monomers 18 by the elastic support bodies; an air guide channel 19 is arranged in the slider, a first connecting channel 20 connected to the support chamber monomer is arranged on one side of the air guide channel, and a second connecting channel 21 connected to the cavity is arranged on the other side; an isolation block 22 is arranged in the cavity near the bottom of the cavity, and the isolation block divides the cavity into the first and second connecting channels 21; A cavity 12a and a second cavity 12b, the first cavity and the second cavity are connected or not connected, when connected, more compressed air can be contained in the cavity, so that the slider in Example 2 can have a better buffering effect on the rapidly expanding exhaust gas, when not connected, the input amount of compressed air in the cavity can be reduced, resources can be saved, and the following isolation body can be compressed more quickly to be destroyed, which is more suitable for the situation where the exhaust gas expands more rapidly than the connected situation; in this scheme, the second connecting channel is connected to the first cavity; the interior of the isolation block is a sandwich structure, one end is provided with a bell mouth 22a connected to the first cavity, and the other end extends out of the device body and is connected to the outside;The isolation block is provided with a first elastic sealing body 23 and a second elastic sealing body 24, the first elastic sealing body and the second elastic sealing body are connected by an isolation body 25, the isolation body is recessed into the first elastic sealing body, the thickness at the middle position is less than the thickness at the edge position, and the thickness of the first elastic sealing body, the second elastic sealing body and the edge of the isolation body are the same; a partition 26 is provided in the isolation block, the partition separates the interior of the isolation block into a first isolation part 27 and a second isolation part 28, the first isolation part is connected to the bell mouth, and the second isolation part is connected to the outside of the device body, a first air outlet 29 is provided on the isolation block at a position corresponding to the first isolation part, and the first air outlet is located in the first elastic sealing body; a second air outlet 30 is provided on the isolation block at a position corresponding to the second isolation part, and the second air outlet is located in the second elastic sealing body. In this structure, when the gas in the cavity is compressed to a certain range and discharged into the interlayer through the bell mouth, the first elastic sealing body expands under the action of the gas. Since the middle position of the isolating body is relatively weak and in a concave state, the compressed gas squeezes it on the side and top surface and eventually cannot withstand the gas pressure and is damaged, so that the first sealing body and the second sealing body are connected, and then the compressed gas passes through the first isolating part, the first air outlet, the first sealing body, the second sealing body, the second air outlet and the second isolating part in sequence and finally discharged out of the device body, so that a secondary buffer can be formed for the expanded exhaust gas, which can free up more adjustment time for the staff, improve the safety performance of the catalytic oxidation device, and further prevent the exhaust gas pressure from increasing rapidly and being discharged through the pressure relief valve to pollute the environment. ;

[0031] In Example 2 and Example 3, the first elastic sealing body, the second elastic sealing body and the isolating body can all be made of high temperature resistant silicone material. In Example 2, the elastic shielding body and the elastic supporting body can all be made of high temperature resistant rubber or high temperature resistant silicone material. In Example 1 to Example 3, the two heat exchange chambers are preferably honeycomb ceramic heat storage bodies fixed in the device body. After using honeycomb ceramics as heat storage bodies, it has been tested that the heat recovery efficiency can be as high as 90% or more. The motor thermal device can be disconnected during operation without the need for electric heating compensation. At the same time, when the equipment is shut down, energy can be stored inside. After the next operation, there is no need to start the electric heating device. The whole process only requires starting the electric heating device at the beginning of the work. In the future, as long as the temperature in the furnace is not artificially lowered or there is a valve leak, there is no need to use electricity. Conventional heat recovery uses plate or tube heat exchangers, and the collection efficiency is about 60%, resulting in excessive exhaust temperature, and electric heating compensation is used. In this device, the catalyst layer in the catalytic chamber can make the initial reaction temperature of the exhaust gas about 250-300°C, which is much lower than the combustion temperature of the direct combustion method of 650-800°C, so the energy consumption is much lower than that of the direct combustion method. At the same time, under the active action of the catalyst, the heat released by the gas after the reaction is recovered by the ceramic heat storage body, which can greatly save energy.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
