Description

Technical Field

[0001] The invention relates to the technical field of industrial waste gas incineration, and in particular to an industrial waste gas incineration device and a use method thereof. Background Art

[0002] Industrial waste gas incineration is a method of treating harmful or unwanted gas emissions generated in industrial production. It aims to convert harmful chemicals in the waste gas into relatively harmless substances such as water and carbon dioxide or reduce their content to environmentally acceptable standards through a high-temperature oxidation process.

[0003] During the use of existing industrial waste gas incineration devices, since the waste gas contains a large amount of dust particles and some macromolecular organic compounds, the waste gas is easy to adhere to the inner wall of the pipe after entering the device, affecting the circulation of the gas, or it is in contact with the fuel during the incineration stage and adsorbed, resulting in incomplete combustion of the fuel. Therefore, the existing device is usually equipped with a dust removal net to filter the dust particles or some macromolecular organic compounds in the waste gas. However, after a long period of use, a large amount of substances are easily attached to the surface of the dust removal net, resulting in poor gas circulation, thereby affecting the efficiency of the waste gas entering the device for incineration. When the existing device is in use, due to the large specific heat capacity of water, water is usually used as a means of heat recovery to recover the heat energy of the gas after incineration. However, when encountering a gas with a small flow rate, the heat energy in the gas cannot completely heat the large amount of water inside the device, resulting in serious heat energy loss.

[0030] The embodiment of the present application provides an industrial waste gas incineration device and a method of use, and the industrial waste gas incineration device and the method of use are described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0031] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods. Example

[0032] See also Figure 1-12In this embodiment, an industrial waste gas incineration device is provided, including: a box body 1, one side of the box body 1 is connected to an air inlet pipe, a dust removal chamber 101 is opened inside the box body 1, a mounting block 2 is installed inside the dust removal chamber 101, a heating chamber 3 is provided inside the box body 1, a primary incineration chamber 4 and a secondary incineration chamber 401 are provided inside the box body 1, two heat exchange chambers 7 are provided inside the box body 1, and a dehumidification box 8 is provided on one side of the box body 1; a dust removal component arranged inside the dust removal chamber 101, for removing dust particles in the waste gas; an adjustment component arranged inside the box body 1, for selecting the use of the heat exchange chamber 7 according to the size of the waste gas flow; and a heat energy recovery component arranged inside the heat exchange chamber 7 and the heating chamber 3, for recovering and utilizing the heat energy of the gas after incineration.

[0033] Among them, through the setting of the dust removal component, the dust particles or some large molecular organic compounds in the exhaust gas can be filtered, collected and processed, which can reduce the competitive adsorption and blocking phenomena in the incineration stage, thereby improving the incineration efficiency. At the same time, the external force applied during the gas flow is used to drive the filter 208 to shake and collide up and down, so that the materials attached to the filter 208 fall off, thereby ensuring the gas flowability of the filter 208; secondly, through the coordinated setting of the adjustment component and the heat recovery component, different heat exchange chambers 7 can be adjusted and used according to the flow rate of the exhaust gas, thereby improving the efficiency of heat recovery, and transferring the recovered heat energy to the heating chamber 3 to preheat the exhaust gas, thereby reducing the heating demand and indirectly improving the overall reaction speed and efficiency. Example

[0034] On the basis of Example 1, an air vent is provided inside the mounting block 2, and the dust removal assembly includes: a plurality of arc blocks 201 connected to the inside of the air vent, and the plurality of arc blocks 201 are evenly distributed in a circular array; a collecting box 203 is provided inside the air vent, and a plurality of connecting plates 204 corresponding to the positions of the arc blocks 201 are connected to the outside of the collecting box 203; two annular plates 206 distributed up and down and connected to the inside of the air vent, and a filter screen 208 is provided between the two annular plates 206; a dust removal net 102 is provided inside the dust removal chamber 101, a card slot 202 is provided on the arc block 201, a card block 205 matching the card slot 202 is connected to the bottom of the connecting plate 204, a plurality of evenly distributed reset springs 207 are connected between the filter screen 208 and the two annular plates 206, and an L-shaped impact rod 2061 is connected to the inner walls of the two annular plates 206.

[0035] Before the waste gas is incinerated, due to the large amount of dust particles and some macromolecular organic matter mixed in the waste gas, it is easy to adhere to the inner wall of the pipe during the waste gas input process, affecting the flow rate of the waste gas. At the same time, a large amount of dust particles are easily released from the fuel, affecting the combustion efficiency of the fuel. Therefore, before the waste gas is discharged into the primary incineration chamber 4, the waste gas is discharged into the dust removal chamber 101. At this time, the waste gas is blown into the filter screen 208 through the gap between the arc blocks 201, and the dust particles and some macromolecular organic matter in the waste gas are processed by the filter screen 208. Then, the dust removal net 102 is set to perform adsorption and filtration again to minimize the dust particles and macromolecular organic matter in the waste gas.

[0036] Then, when the exhaust gas passes through the filter 208, the filter 208 applies a certain external force to the filter 208, so that the filter 208 moves. The upper and lower surfaces of the filter 208 are provided with return springs 207. At this time, the filter 208 continuously squeezes or stretches the return spring 207 during its movement, so that the return spring 207 generates elastic force, and the elastic force is applied back to the filter 208, so that the filter 208 continuously shakes up and down, and the dust particles and macromolecular organic matter attached to the filter 208 are shaken off. At the same time, when the filter 208 shakes up and down, it collides with the impact rod 2061, so as to shake off the dust particles on the filter 208, thereby reducing the dust particles adhering to the filter 208, resulting in a decrease in the flow rate of the exhaust gas passing through the filter 208, affecting the efficiency of the exhaust gas incineration treatment, and the particles or macromolecular organic matter shaken off fall into the collection box 203; After the waste gas incineration is completed, the dust removal chamber 101 can be opened through the box door on the front side of the box body 1, and then the collection box 203 can be lifted from the bottom. At this time, the block 205 at the bottom of the connecting plate 204 is separated from the card slot 202, and then the collection box 203 is rotated to make the connecting plate 204 move to the gap between the arc blocks 201, and then the collection box 203 is moved down, and the collection box 203 can be taken out from the mounting block 2, and the dust impurities collected in the collection box 203 can be processed. After the processing is completed, the collection box 203 can be reloaded into the mounting block 2. Example

[0037] On the basis of Example 1, an air duct 301 is provided inside the box body 1, and one end of the air duct 301 is communicated with the dust removal chamber 101, and the other end of the air duct 301 passes through the heating chamber 3 and is communicated with the primary incineration chamber 4, the primary incineration chamber 4 is located below the secondary incineration chamber 401, and a conduit 404 is connected between the primary incineration chamber 4 and the secondary incineration chamber 401, a waste box 403 is provided inside the primary incineration chamber 4, and igniters 402 are installed inside the primary incineration chamber 4 and the secondary incineration chamber 401, a fuel pipe 405 is installed on the top of the box body 1, the fuel pipe 405 passes through the secondary incineration chamber 401 and extends into the primary incineration chamber 4, and an atomizing nozzle 406 is installed on one side of the fuel pipe 405.

[0038] The gas after dust removal and filtration enters the air duct 301 and is discharged into the primary incineration chamber 4 through the air duct 301. At this time, the fuel is sprayed into the primary incineration chamber 4 and the secondary incineration chamber 401 through the fuel pipe 405 and the atomizing nozzle 406, and the fuel is ignited by the igniter 402, so that the exhaust gas is incinerated in the primary incineration chamber 4. As the exhaust gas is continuously injected, the exhaust gas above the primary incineration chamber 4 is discharged into the secondary incineration chamber 401 through the conduit 404 for secondary incineration, thereby ensuring the complete incineration of harmful substances in the exhaust gas. At the same time, through the setting of the atomizing nozzle 406, the fuel can be atomized and sprayed, thereby increasing the contact area with the exhaust gas and the combustion area, allowing the fuel to burn more efficiently. The fuel sprayed from the fuel pipe 405 is natural gas or liquefied petroleum gas.

[0039] On the basis of Example 1 and Example 3, further, the adjustment component includes: an air flow sensor 302 installed inside the air duct 301; a first exhaust fan 501 and a second exhaust fan 502 installed on the top of the box 1, and the power of the first exhaust fan 501 is greater than the power of the second exhaust fan 502; an exhaust pipe 5 connected to the inside of the box 1, one end of the exhaust pipe 5 is connected to the secondary incineration chamber 401, and the other end of the exhaust pipe 5 is respectively connected to the first exhaust fan 501 and the second exhaust fan 502; a three-way pipe 503 connected between the first exhaust fan 501 and the second exhaust fan 502, one end of the three-way pipe 503 is connected to the air supply pipe 504, one end of the air supply pipe 504 extends to the inside of the box 1 and is connected to the adjustment block 6, and a control panel is installed on the surface of the box 1, and the control panel is electrically connected to the first exhaust fan 501 and the second exhaust fan 502.

[0040] When the exhaust gas passes through the air duct 301, the air flow sensor 302 is set to monitor the exhaust gas flow discharged into the box 1 for incineration treatment, and transmit the monitoring data to the control panel, and control the start-up of the first exhaust fan 501 or the second exhaust fan 502 through the flow threshold set in advance in the control panel. When the exhaust gas flow is large, the control panel controls the start-up of the first exhaust fan 501, so that the first exhaust fan 501 draws the exhaust gas in the secondary incineration chamber 401 into the three-way pipe 503 through the exhaust pipe 5, and discharges it into the regulating block 6 through the air supply pipe 504. When the exhaust gas flow is low, the second exhaust fan 502 is controlled to start. Since the power of the first exhaust fan 501 is greater than that of the second exhaust fan 502, exhaust fans of different powers can be selected and adjusted according to the flow of the exhaust gas to be incinerated, thereby reducing power loss and achieving energy-saving effects.

[0041] Among them, the interior of the regulating block 6 is a hollow structure, and two ventilation plates 601 are connected inside the regulating block 6, and the ventilation plates 601 are located on both sides of the pipe mouth of the gas supply pipe 504, and a ventilation hole is opened in the middle of the ventilation plate 601. One side of the ventilation plate 601 is connected to multiple evenly distributed connecting springs 602, and one end of the connecting spring 602 is connected to a blocking block 603. One end of the regulating block 6 is connected to the first air outlet pipe 604, and the bottom of the regulating block 6 is connected to the second air outlet pipe 605. The first air outlet pipe 604 and the second air outlet pipe 605 are respectively connected to the two heat exchange chambers 7.

[0042] When the first exhaust fan 501 is started, the gas flow rate entering the regulating block 6 is large. At this time, the blocking block 603 near the first outlet pipe 604 is pushed by the gas and is away from the ventilation plate 601, while the blocking block 603 near the second outlet pipe 605 is pressed by the gas and is close to the ventilation plate 601. Therefore, the gas in the regulating block 6 is discharged into the second heat exchange cavity through the first outlet pipe 604. When the second exhaust fan 502 is started, the gas flow rate entering the regulating block 6 is small. At this time, the blocking block 603 near the first outlet pipe 605 is pressed by the gas and is close to the ventilation plate 601. The thrust applied to the blocking block 603 at 604 is smaller than the elastic force applied by the connecting spring 602, so that the blocking block 603 remains in place to seal the ventilation plate 601, and the blocking block 603 at the second air outlet pipe 605 is subjected to the pressure of the gas. When the pressure applied to the blocking block 603 is smaller than the elastic force applied by the connecting spring 602, the blocking block 603 is separated from the ventilation plate 601 under the action of the elastic force of the connecting spring 602. At this time, the gas in the regulating block 6 is discharged into the first heat exchange chamber through the second air outlet pipe 605. Example

[0043] On the basis of Example 1, the heat energy recovery component includes: two heat exchange chambers 7 are divided into a first heat exchange chamber and a second heat exchange chamber; a first heat exchange tube 701 is arranged inside the first heat exchange chamber; a second heat exchange tube 702 is arranged inside the second heat exchange chamber; a first heating tube 303 and a second heating tube 304 are arranged inside the heating chamber 3, and the first heating tube 303 and the second heating tube 304 are both arranged in a threaded structure, the two ends of the first heat exchange tube 701 are respectively connected to the two ends of the first heating tube 303, and the two ends of the second heat exchange tube 702 are respectively connected to the two ends of the second heating tube 304, the number of first heating tubes 303 is less than the number of second heating tubes 304, one side of the heat exchange chamber 7 is connected to a water outlet pipe, the front of the first heat exchange chamber and the top of the second heat exchange chamber are both connected to a water inlet pipe, an exhaust pipe 703 is connected between the box body 1 and the dehumidification box 8, and one end of the exhaust pipe 703 is communicated with the two heat exchange chambers 7 respectively, and a plurality of dehumidification nets 801 are installed inside the dehumidification box 8.

[0044] After the gas enters the heat exchange chamber 7, the impurities generated by the combustion in the gas are filtered again by the water inside the heat exchange chamber 7, thereby reducing the content of harmful substances in the gas and absorbing the heat energy carried by the gas. At the same time, the heat in the heat exchange chamber 7 is transferred to the heating chamber 3 through the first heat exchange tube 701 or the second heat exchange tube 702, and the air guide tube 301 in the heating chamber 3 is heated, thereby preheating the exhaust gas passing through the air guide tube 301; Then, the internal space of the first heat exchange cavity is larger than the internal space of the second heat exchange cavity. When the exhaust gas is discharged into the second heat exchange cavity through the first outlet pipe 604, the heat is transferred to the second heating tube 304 through the second heat exchange tube 702. When the gas is discharged into the first heat exchange cavity through the second outlet pipe 605, the heat is transferred to the first heating tube 303 through the first heat exchange tube 701. When the gas flow rate is large, the gas enters the second heat exchange chamber with a larger space. At this time, the water capacity in the second heat exchange chamber is large, which can absorb more heat carried by the gas and transfer the heat through the second heat exchange tubes 702 with a larger number. When the gas flow rate is small, the gas enters the first heat exchange chamber with a small space for heat energy recovery. Different heat energy recovery modes can be switched according to the flow rate of the exhaust gas discharge, thereby avoiding that when the gas flow rate is small, after the gas is discharged into the second heat exchange chamber with a larger space, the heat carried by the gas cannot meet the temperature of heating all the water to the temperature that meets the heat conduction of the second heat exchange tube 702, resulting in all the heat energy of the gas being lost in heating the water, causing a waste of heat energy. Therefore, when the exhaust gas discharge flow rate is small, the incinerated gas is introduced into the first heat exchange chamber with a small space, so that the heat energy in the gas heats the water in the first heat exchange chamber and transfers the heat energy through the first heat exchange tubes 701 with a smaller number, thereby avoiding the excessive number of first heat exchange tubes 701 and increasing the loss of heat energy in the transfer process; The gas after passing through the heat exchange chamber 7 is discharged into the dehumidification box 8 through the exhaust pipe 703, and the moisture contained in the gas is processed by the dehumidification net in the dehumidification box 8.

[0045] By providing the water inlet pipe and the water outlet pipe, the water in the heat exchange chamber 7 can be replaced.
