[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0026] Example
[0027] like Figures 1-6 As shown, an environmentally friendly combustion treatment device for industrial waste gas includes: a treatment box 1, a waste gas inlet pipe 101 installed on one side of the top of the treatment box 1, a gas collection hopper 102 installed on one side inside the treatment box 1, a high-pressure turbine blower 103 installed at the bottom of the gas collection hopper 102, a combustion chamber 104 installed inside the treatment box 1, a ceramic heat storage chamber 111 installed inside the combustion chamber 104, a connecting pipe 114 installed at the outer end of the ceramic heat storage chamber 111, a filter assembly set on the top of the gas collection hopper 102, the filter assembly including: an air intake hole 105, a filter screen plate 106, a placement plate 107, an air inlet hole 108, a mounting frame 109 and a filter bag 110, and a preheating assembly set inside the treatment box 1, the preheating assembly including: a preheating box 2, a preheating pipe 201, a heat exchanger 202, an air outlet pipe 203, a heat exhaust pipe 204 and an exhaust pipe 205.
[0028] The gas collecting hopper 102 has multiple air intake holes 105 at its top. A filter screen plate 106 is installed at the top of the inside of the processing box 1. A placement plate 107 is installed at the bottom of the filter screen plate 106. An air inlet hole 108 is opened at the top of the placement plate 107 relative to the multiple air intake holes 105. An installation frame 109 is installed at the bottom of each air inlet hole 108. A filter bag 110 is installed inside the installation frame 109.
[0029] When the processing box 1 is in use, the waste gas inlet pipe 101 can be connected with the waste gas outlet pipe in the workshop, and the high-pressure turbine blower 103 is started. Since the inlet end of the high-pressure turbine blower 103 is connected with the gas collecting hood 102, the high-pressure turbine blower 103 generates strong negative pressure suction on the gas collecting hood 102, and then on the air suction hole 105, the filter bag 110, the air inlet hole 108 and the waste gas inlet pipe 101, so that the industrial waste gas is sucked into the processing box 1. When the waste gas passes through the filter screen plate 106, the filter screen plate 106 can filter out large-particle impurities in the waste gas, and the filter bag 110 can perform secondary filtration on the waste gas to filter out small-particle and fine-particle impurities in the waste gas. Therefore, the filter screen plate 106 and the filter bag 110 can play a dual role of filtering dust and particle impurities in the waste gas. Moreover, the filter screen plate 106 and the filter bag 110 can be separately disassembled and cleaned, so that the disassembly speed is accelerated and the working efficiency of the industrial waste gas filtration and purification treatment is improved.
[0030] The two sides of the top end of the processing box 1 are both provided with a fixing block 4.

[0031] The bottom of the air inlet hole 108 is provided with a connecting head 5, and the top of the mounting frame 109 is provided with an outer thread layer 501 which is threadedly connected with the connecting head 5. When the filter bag 110 is used, the filter bag 110 is mounted in the mounting frame 109, and is shaped by the mounting frame 109, so that the filter bag 110 is in a straight and tight state, avoiding the bending of the filter bag 110 which affects the use of the filter bag 110 in filtering dust and impurities in the waste gas. The filter bag 110 can be mounted on the connecting head 5 at the bottom of the placing plate 107 through the mounting frame 109, so that the filter bag 110 is suspended in the processing box 1. When the filter bag 110 collects dust and impurities, the mounting frame 109 can be disassembled from the connecting head 5, so that the dust and impurities in the filter bag 110 can be easily cleaned.
[0032] The cleaning door 6 is rotatably connected with the filter screen plate 106 and the filter bag 110 through hinges at the positions of the filter screen plate 106 and the filter bag 110 on the outer side of the processing box 1. An observation window 601 is installed on the cleaning door 6. When the filter screen plate 106 and the filter bag 110 are used, the separation of the filter screen plate 106 and the collection of the filter bag 110 can be observed through the observation window 601. When the filter screen plate 106 separates too many impurities or the filter bag 110 collects too much, the cleaning door 6 can be opened in time to clean the filter screen plate 106 or the filter bag 110, avoiding affecting the normal use of the filter screen plate 106 and the filter bag 110.
[0033] Wherein, the ceramic regenerator 111 top is equipped with the burner 112, the burner 112 outer end one side is equipped with the gas inlet pipe 113, after the dust and impurities in the exhaust gas are filtered clean, the exhaust gas is discharged into the preheating pipe 201 by high pressure turbine blower 103, and is discharged into the ceramic regenerator 111 inside from the connecting pipe 114, at this time, start the burner 112 work, its gas inlet pipe 113 outer end can access natural gas pipe, the natural gas is discharged into the burner 112, the burner 112 working point ignites after can make the natural gas burn inside the ceramic regenerator 111, the exhaust gas directly burns under high temperature conditions, and the organic matter (VOCs) is oxidized into carbon dioxide and water.
[0034] Wherein, the combustion chamber 104 bottom is equipped with the preheating box 2, the preheating box 2 inside is equipped with the preheating pipe 201, the preheating pipe 201 one end is connected with the connecting pipe 114, the preheating pipe 201 other end is connected with the outlet end of high pressure turbine blower 103, the preheating pipe 201 one side is equipped with the heat exchanger 202, the heat exchanger 202 and ceramic regenerator 111 between are equipped with the outlet pipe 203, the heat exchanger 202 and preheating box 2 between are equipped with the heat removal pipe 204, the heat exchanger 202 top one side is equipped with the exhaust pipe 205, and the exhaust pipe 205 penetrates in the processing box 1 outside.
[0035] In the ceramic regenerator 111 inside, the exhaust gas is high-temperature combustion, and after the organic matter (VOCs) is oxidized into carbon dioxide and water, the exhaust gas is purified and treated, and the clean gas is discharged from the outlet pipe 203 to the heat exchanger 202. Since the temperature of the gas after combustion is high, after being discharged into the heat exchanger 202, the heat in the gas will be transferred from the high-temperature side to the low-temperature side. The heat exchanger 202 and the preheating box 2 are equipped with the heat removal pipe 204. The preheating box 2 belongs to the low-temperature side, that is, the heat in the gas will be transferred to the inside of the preheating box 2. When the exhaust gas flows in the preheating pipe 201, the recovered heat is used to preheat the exhaust gas. The cold exhaust gas is preheated to become hot exhaust gas, so that the exhaust gas can be fully combusted, thereby effectively treating and purifying the organic matter (VOCs) in the exhaust gas, and also avoiding the heat from the gas discharged into the atmosphere to accelerate climate warming.
[0036] The preheating box 2 top and the connecting pipe 114 between are equipped with the flow pipe, the heat entering the preheating box 2 inside is preheated to the exhaust gas, and also discharged into the connecting pipe 114 through the flow pipe, and flows to the ceramic regenerator 111 again. This ensures the safe use of the preheating box 2, and also circulates the recovered heat, avoids waste of heat, and the heat in the gas is exchanged, which reduces the temperature and slowly cools down. The gas can be discharged from the exhaust pipe 205 to the outside of the processing box 1.
[0037] The inclined block 3 is installed at the bottom end of the ceramic regenerator 111, the drain pipe 301 is installed at one side of the bottom of the ceramic regenerator 111, the drain valve 302 is installed on the drain pipe 301, after the carbon dioxide and water are generated by burning the exhaust gas in the ceramic regenerator 111, the carbon dioxide is discharged from the gas outlet pipe 203 together with the gas, and a part of the water is changed into steam after being heated by high temperature, and the steam is also discharged together with the gas, when there is accumulated water in the ceramic regenerator 111, the accumulated water is gathered on one side through the inclined block 3, the drain valve 302 is started to be opened, and the drain pipe 301 can quickly discharge the accumulated water, so that the normal use of the ceramic regenerator 111 is avoided.
[0038] Working principle:
[0039] When the treatment box 1 is used, the exhaust gas inlet pipe 101 can be connected with the exhaust gas discharge pipeline in the workshop, the high-pressure turbine blower 103 is started, the gas collecting hopper 102 is connected with the gas inlet end of the high-pressure turbine blower 103, the high-pressure turbine blower 103 generates strong negative pressure suction on the gas collecting hopper 102, and then the suction hole 105, the filter bag 110, the gas inlet hole 108 and the exhaust gas inlet pipe 101 absorb the exhaust gas, so that the industrial exhaust gas is sucked into the treatment box 1, when the exhaust gas passes through the filter screen 106, the filter screen 106 can filter out the large-particle impurities in the exhaust gas, and the filter bag 110 can filter out the small-particle and fine-particle impurities in the exhaust gas, so that the filter screen 106 and the filter bag 110 can play a double filtering role on the dust and particle impurities in the exhaust gas, and the filter screen 106 and the filter bag 110 can be separately disassembled and cleaned, so that the disassembly speed is accelerated, and the working efficiency of the industrial exhaust gas filtering and purification treatment is improved.
[0040] After the dust and impurities in the exhaust gas are filtered out, the exhaust gas is discharged into the preheating pipe 201 by the high-pressure turbine blower 103, and is discharged into the ceramic regenerator 111 through the connecting pipe 114, at this time, the burner 112 is started to work, the gas inlet pipe 113 of the burner 112 can be connected with the natural gas pipe, the natural gas is discharged into the burner 112, the burner 112 is ignited after working, so that the natural gas is burned in the ceramic regenerator 111, the organic matter (VOCs) is oxidized into carbon dioxide and water under high temperature.
[0041] The waste gas is combusted at high temperature inside the ceramic regenerator 111, and the organic matter (VOCs) is oxidized into carbon dioxide and water, and then the waste gas is purified, and the clean gas is discharged from the gas outlet pipe 203 to the heat exchanger 202. Since the temperature of the combusted gas is high, when the gas is discharged into the heat exchanger 202, the heat in the gas will be transferred from the high-temperature side to the low-temperature side. The heat exchanger 202 is installed with a heat exhaust pipe 204 between the heat exchanger 202 and the preheating tank 2. The preheating tank 2 belongs to the low-temperature side, that is, the heat in the gas will be transferred to the inside of the preheating tank 2. When the waste gas flows in the preheating pipe 201, the waste gas is preheated by the recovered heat. The cold waste gas is preheated to become hot waste gas, so that the waste gas can be fully combusted, and the organic matter (VOCs) in the waste gas can be effectively treated and purified. In addition, the heat can be avoided from being discharged into the atmosphere to accelerate climate warming.
