Description

Technical Field

[0001] The invention belongs to the technical field of incineration flue gas treatment, and specifically relates to an organic waste gas and waste liquid incineration flue gas treatment device and system. Background Art

[0002] Incineration of organic waste gas and waste liquid is a method of treating waste gas and waste liquid containing organic compounds by high-temperature incineration. However, during incineration, a large amount of incineration waste gas will be discharged. The incineration waste gas contains a large amount of dust and sulfide. When discharged into the air, it will cause great pollution to the atmosphere. During the use of existing incineration waste gas treatment equipment, different equipment needs to be used in conjunction with the incineration waste gas for dust removal, cooling and sulfide precipitation treatment in turn before discharge. There are many equipment involved, which is not easy to manage. At the same time, the waste generated during the treatment process needs to be manually cleaned regularly.

[0003] The existing Chinese patent document with publication number CN111957193B proposes an incineration waste gas treatment device, which is configured to allow the incineration waste gas to enter the cooling chamber after being filtered by a filter screen, and to retain the incineration dust in the dust removal chamber. At the same time, the cooling device is started to cool the waste gas in the cooling chamber. The cooled waste gas passes through a first connecting pipe, an air pump and a second connecting pipe in sequence and enters the treatment liquid in the precipitation chamber. After the waste gas reacts with the treatment liquid, the sulfide in the waste gas is converted into a precipitate and precipitated at the bottom of the precipitation chamber. Then, the exhaust pipe is opened to discharge the treated waste gas to the outside to solve the above problem. However, the smoke particles that are not completely burned generated by the incineration of the waste gas and waste liquid are not separated and treated, resulting in serious pollution to the atmosphere after being discharged with the waste gas.

[0004] Therefore, the present invention proposes an organic waste gas and waste liquid incineration flue gas treatment equipment and system to solve the problem that the incompletely burned smoke particles generated by the incineration of waste gas and waste liquid in the prior art are not separated and treated, resulting in serious pollution to the atmosphere after being discharged with the waste gas. The integrated incineration waste gas treatment equipment is designed to separate the incompletely burned smoke particles generated by the incineration of waste gas and waste liquid, and then use gas reflux to make them undergo a secondary full combustion treatment to convert them into harmless stable compounds, thereby achieving the purpose of reducing environmental pollution.

[0033] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1

[0035] See also Figures 1 to 14The present invention provides a technical solution: an organic waste gas and waste liquid incineration flue gas treatment device, comprising an incinerator 1, a gas burner 11 is fixedly installed at one end of the incinerator 1, an organic waste gas inlet pipe 12 is fixedly installed on the inner wall of one side of the incinerator 1, a gas particle separation component 2 is arranged at the other end of the incinerator 1, an SNCR denitration component 4 is arranged at one side of the gas particle separation component 2, an air inlet 5 is arranged below the gas particle separation component 2, the gas particle separation component 2 includes a mixed secondary combustion chamber 21, a particle separation chamber 22, and a gas reflux chamber 23, the SNCR denitration component 4 includes a denitration chamber 41 and a nitrogen emission chamber 42, a particle separator 26 is arranged inside the particle separation chamber 22, and the gas reflux chamber 23 and the denitration chamber A right-angle connecting pipe 3 is fixedly installed between the two combustion chambers 41, a return pipe 1 51 is fixedly installed on the upper side of the air inlet 5 close to the mixed secondary combustion chamber 21, a return pipe 2 52 is fixedly installed on the upper side of the air inlet 5 close to the gas return chamber 23, one end of the mixed secondary combustion chamber 21 is fixedly connected to the other end of the incinerator 1, the particle separation chamber 22 is fixedly installed between the mixed secondary combustion chamber 21 and the particle separation chamber 22, combustible gas input pipes 24 are arranged on the upper sides of the particle separation chamber 22, the upper end of the return pipe 1 51 is fixedly connected to the bottom inner wall of the mixed secondary combustion chamber 21, an electronic igniter 25 is fixedly installed on the top of the mixed secondary combustion chamber 21, and the upper end of the return pipe 2 52 is fixedly connected to the bottom inner wall of the gas return chamber 23;

[0036] In this embodiment, a waste liquid inlet pipe is arranged above the organic waste gas inlet pipe 12, and the organic waste gas and waste liquid enter the incinerator 1. The gas burner 11 is connected to the combustible gas to incinerate the organic waste gas and waste liquid. A large amount of high-temperature flue gas generated enters the mixed secondary combustion chamber 21, and is separated and filtered out by the particle separator 26 in the particle separation chamber 22 to remove the incompletely burned particles. The high-temperature gas enters the gas reflux chamber 23 through the particle separator 26, and enters the denitrification chamber 41 through the right-angle connecting pipe 3 to denitrify and produce water, nitrogen and other substances. The nitrogen is discharged and refluxed to the air inlet 5 through the nitrogen discharge chamber 42. After the reflux pipe 1 51 and the right-angle connecting pipe 3 are closed, the refluxed nitrogen enters the gas reflux chamber 23 through the reflux pipe 2 52. The flow chamber 23 reversely flushes the particle separator 26, so that the separated and precipitated combustible particle smoke enters the mixed secondary combustion chamber 21 for secondary combustion, closes the reflux pipe 2 52 and opens the reflux pipe 1 51 to allow the reflux nitrogen to directly enter the mixed secondary combustion chamber 21 through the reflux pipe 1 51, thereby reducing the concentration and allowing it to burn fully. The combustible gas input pipe 24 can also be passed with organic waste gas or combustible gas for combustion assistance. The electronic igniter 25 plays an ignition role. The heat energy carried by the reflux nitrogen is reused and recovered by the mixed secondary combustion chamber 21. At the same time, the mixed secondary combustion chamber 21 performs secondary combustion on the combustible gas, so that the flue gas that passes through the mixed secondary combustion chamber 21 again in the later period is heated, effectively utilizing the heat source and playing an energy-saving role.

[0037] Embodiment 2

[0038] See also Figures 1 to 14 On the basis of the first embodiment, in order to separate and filter the particulate dust carried by the flue gas generated by the incineration of organic waste gas and waste liquid, the present embodiment further proposes that the particle separator 26 includes a fixed rear ring 261, the outer surface of the fixed rear ring 261 is fixedly connected to the inner surface of the particle separation chamber 22, and a particle V-shaped plate 262 is evenly distributed on the surface of the fixed rear ring 261 close to the mixed secondary combustion chamber 21, and a front flow divider 263 is fixedly installed at one end of the particle V-shaped plate 262, and gas separation grooves 2621 are symmetrically opened above the particle V-shaped plate 262, and a movable plate 2622 is hingedly installed at one end of the particle V-shaped plate 262 close to the front flow divider 263, and a particle blocking plate 2623 is fixedly installed on the upper surface of the movable plate 2622, and a gas reflux groove 2627 adapted to the particle blocking plate 2623 is opened on the bottom inner wall of the particle V-shaped plate 262 The particle blocking plate 2623 is in the shape of an inverted fin, an open groove 2624 is provided on the inner wall of one side of the movable plate 2622, a magnetic mounting tail plate 2625 is fixedly installed on one end of the movable plate 2622 close to the fixed rear ring 261, a spring 2626 is movably installed on the upper surface of the magnetic mounting tail plate 2625, the upper end of the spring 2626 is movably connected to the lower surface of the particle V-shaped plate 262, and the inner side of the fixed rear ring 261 is evenly distributed with return gas guide plates 2611 corresponding to the movable plate 2622, the upper surface of one end of the return gas guide plate 2611 is movably connected to the inner surface of the fixed rear ring 261, and the upper surface of the other end of the return gas guide plate 2611 is overlapped with the lower surface of the magnetic mounting tail plate 2625, and a group of magnetic blocks with different magnetic properties are respectively provided on the lower surface of the magnetic mounting tail plate 2625 and the upper surface of the return gas guide plate 2611;

[0039] In this embodiment, the specific separation function of the particle separator 26 is that the flue gas carrying particles enters the gas reflow chamber 23, and the particle V-shaped plate 262 uses the principle that the particle dust will gather and adsorb, so that the exhaust gas can be discharged through the oblique gas separation grooves 2621 opened on the wing sheets on both sides of the particle V-shaped plate 262, enter the inner side of the particle V-shaped plate 262, and enter the gas reflow chamber 23 through the middle of the fixed rear circle 261, and the separated particle dust will gather in the groove of the particle V-shaped plate 262, which plays a role of separation and filtration. The particle separator 26 is reversely flushed by the airflow, and after filtering for a period of time, the refluxed nitrogen enters the gas reflow chamber 23. At this time, the right-angle connecting pipe 3 is closed, and the refluxed nitrogen will reversely enter the interior of the fixed rear circle 261. The front diversion cover 263 is closed, so under the action of the airflow, the refluxed nitrogen will enter the fixed rear circle 261. The current gas guide plate 2611 is lifted up, because the return gas guide plate 2611 is below the magnetic mounting tail plate 2625, the movable plate 2622 is further lifted up, the spring 2626 is compressed, and the particle blocking plate 2623 passes through the gas reflux groove 2627.

[0040] Embodiment 3

[0041] See also Figures 1 to 14 On the basis of the second embodiment, in order to increase the guiding effect on the gas, this embodiment further proposes that a diverter groove 2631 adapted to the particle V-shaped plate 262 is opened on the outer surface of the front diverter cover 263, and a return gas guide ring 264 is fixedly installed on the other side surface of the fixed rear ring 261; in this embodiment, the fixed rear ring 261 mainly plays the role of fixing the particle V-shaped plate 262, and the front diverter cover 263 mainly plays the role of closing the front end of the particle V-shaped plate 262, so that the flue gas carrying particles can only be separated and filtered through the outside of the particle V-shaped plate 262, the diverter groove 2631 plays the role of diverting and guiding the flue gas, so that the flue gas is evenly dispersed on the surface of the particle V-shaped plate 262 for separation, and the return gas guide ring 264 plays a guiding role on the return gas, increasing the flow rate of the return gas so that it enters the inner side of the particle V-shaped plate 262 for reverse flushing.

[0042] Embodiment 4

[0043] See also Figures 1 to 14On the basis of the third embodiment, in order to make the filtered gas undergo denitration treatment, the present embodiment further proposes that the interior of the denitration chamber 41 is sequentially provided with a primary flow spoiler 413, a secondary flow spoiler 414 and a tertiary flow spoiler 415, the outer surfaces of the primary flow spoiler 413, the secondary flow spoiler 414 and the tertiary flow spoiler 415 are respectively fixedly connected to the inner surface of the denitration chamber 41, the inner diameters of the primary flow spoiler 413, the secondary flow spoiler 414 and the tertiary flow spoiler 415 are successively reduced, the inner surfaces of the primary flow spoiler 413, the secondary flow spoiler 414 and the tertiary flow spoiler 415 are all provided with spiral guide grooves, and a reactant is provided in the middle of the denitration chamber 41. A spray pipe 412, a reactant adding pipe 4122 is fixedly installed on the inner wall of the reactant spray pipe 412, the outer surface of the reactant adding pipe 4122 is fixedly connected to the top inner wall of the denitration chamber 41, and spray branches 4121 are evenly distributed on the side wall of the reactant spray pipe 412. The nitrogen discharge chamber 42 is fixedly connected to the denitration chamber 41, and a wastewater discharge pipe 411 is fixedly installed in the middle of the side wall of the denitration chamber 41. A demisting net 423 is fixedly installed inside one end of the nitrogen discharge chamber 42 close to the denitration chamber 41, a main discharge pipe 421 is fixedly installed in the middle of the side wall of the nitrogen discharge chamber 42, and a reflux connecting pipe 422 is set at one end of the nitrogen discharge chamber 42;

[0044] In this embodiment, the spray branch pipe 4121 and the inner surfaces of the first-stage spoiler 413, the second-stage spoiler 414, and the third-stage spoiler 415 have a 60° convection flushing effect. The spiral guide grooves arranged on the inner surfaces of the first-stage spoiler 413, the second-stage spoiler 414, and the third-stage spoiler 415 are opposite to the flow direction of the gas. The separated and filtered gas enters the denitration chamber 41, and a reducing agent such as ammonia water, urea, etc. is injected into the reactant spray pipe 412 through the reactant adding pipe 4122. The spray branch pipe 4121 sprays, and the high-temperature gas is used to react with the reducing agent to generate water and nitrogen, which enter the nitrogen discharge chamber 42. Internally, the mist removal net 423 is a dense net that can isolate foam, so that most of the nitrogen is discharged through the main discharge pipe 421 to reduce pollution, and water can be discharged through the wastewater discharge pipe 411. The reflux connecting pipe 422 can be connected to the air intake duct 5 through a pipeline to allow part of the nitrogen to reflux. The inner diameters of the first-stage spoiler 413, the second-stage spoiler 414 and the third-stage spoiler 415 are reduced in sequence to reduce the flow rate of the gas. The spray branch pipe 4121 sprays the reducing agent to generate convection with the first-stage spoiler 413, the second-stage spoiler 414 and the third-stage spoiler 415, and flows in the spiral guide groove to fully contact and react with the gas to improve the denitrification effect.

[0045] Embodiment 5

[0046] See also Figures 1 to 14 Based on the fourth embodiment, this embodiment further proposes a system for treating flue gas from incineration of organic waste gas and waste liquid, wherein the specific operation process includes the following steps:

[0047] Step 1: Organic waste gas and waste liquid enter the incinerator 1, and the gas burner 11 is connected to the combustible gas to incinerate the organic waste gas and waste liquid. A large amount of high-temperature flue gas generated enters the mixed secondary combustion chamber 21. At this time, the return pipe 2 52 and the return pipe 1 51 are closed, and the valve of the right-angle connecting pipe 3 is opened;

[0048] Step 2: The flue gas carrying particles enters the particle separation chamber 22 through the mixing secondary combustion chamber 21. The particle V-shaped plate 262 uses the principle that the particles and dust will gather and adsorb, so that the exhaust gas can be discharged through the upwardly inclined gas separation grooves 2621 opened on the wings on both sides of the particle V-shaped plate 262, enter the inner side of the particle V-shaped plate 262, and enter the gas reflow chamber 23 through the middle of the fixed rear ring 261, and the separated particle dust will gather in the groove of the particle V-shaped plate 262;

[0049] Step 3: The gas enters the denitration chamber 41 through the right-angle connecting pipe 3, and a reducing agent such as ammonia water, urea and the like is injected into the reactant spray pipe 412 through the reactant adding pipe 4122. The spray branch pipe 4121 sprays the reactant, and the high-temperature gas reacts with the reactant to produce water and nitrogen. The nitrogen enters the nitrogen discharge chamber 42, and the water can be discharged through the wastewater discharge pipe 411. The reflux connecting pipe 422 can be connected to the air inlet 5 through a pipeline to reflux a part of the nitrogen. At this time, the main discharge pipe 421 and the right-angle connecting pipe 3 are closed, and the reflux pipe 2 52 is opened;

[0050] Step four, the refluxed nitrogen enters the gas reflux chamber 23, and the front diversion cover 263 is closed. Therefore, under the action of the airflow, the reflux gas guide plate 2611 is lifted up, and the movable plate 2622 is further lifted up, the spring 2626 is compressed, and the particle blocking plate 2623 passes through the gas reflux groove 2627. Due to the special shape of the particle blocking plate 2623 and the opening of the open groove 2624, the gas escapes through the gas reflux groove 2627, and the particle dust in the groove of the particle V-shaped plate 262 is reversely flushed to the inside of the mixed secondary combustion chamber 21. The combustible gas inlet pipe 24 can replenish the combustible gas or organic waste gas, and the electronic igniter 25 ignites for secondary combustion treatment. Finally, the reflux pipe 2 52 and the reflux pipe 1 51 are closed again, and the right-angle connecting pipe 3 is opened, and step one is repeated.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
