[0002] Volatile matter refers to the part of a substance that can evaporate under specific conditions. In the coal industry, volatile matter is one of the important indicators for evaluating coal quality. It reflects the degree of coal metamorphism. Generally speaking, the higher the volatile matter content, the lower the degree of coal metamorphism. The secondary combustion chamber, that is, the secondary combustion chamber, plays an important role in waste treatment and other fields. When the products of the primary combustion enter the secondary combustion chamber, they are further burned under higher temperature and more sufficient oxygen conditions to ensure that the combustible components in the waste are burned as completely as possible, reduce the emission of incomplete combustion products such as carbon monoxide and hydrocarbons, and improve combustion efficiency. For the treatment of hazardous waste, the secondary combustion chamber can make the harmful substances therein more thoroughly destroyed, and can decompose the harmful substances to achieve the purpose of harmless treatment.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0029] In the following description, “left”, “right”, “front”, “back”, “up” and “down” are used to refer to Figure 1 The viewing direction is oriented.

[0030] Example 1: In some embodiments, please refer to the accompanying drawings of the specification. Figure 1-Figure 7 , an energy-saving flue gas incineration equipment, including a frame 1, a combustion device 2 is installed on the left side of the frame 1, a combustion-supporting device 3 is installed on the front side of the combustion device 2, a heat exchanger 4 is fixedly installed on the middle side of the frame 1, a quenching tower 5 is fixedly installed on the right side of the frame 1, a vertical cleaning device 6 is installed in the combustion device 2, the right side of the combustion device 2 is fixedly connected to the input port of the heat exchanger 4 through a pipeline, the hot fluid output port of the heat exchanger 4 is fixedly connected to the combustion-supporting device 3, and the cold fluid output port of the heat exchanger 4 is fixedly connected to the input port of the quenching tower 5.

[0031] The volatile matter burns in the combustion device 2, and the heat generated by the combustion is transferred to the combustion-supporting device 3 through the heat exchanger. The combustion-supporting device 3 supports the combustion of the combustion device 2, which not only reduces the flue gas temperature reaching the quenching tower 5, but also reduces the fuel loss in the combustion device 2. The high-temperature flue gas generated by the combustion of the volatile matter is further processed by the heat exchanger 4 and the quenching tower 5, making the gas emission pollution less. At the same time, the vertical cleaning device 6 regularly cleans the waste residue on the inner wall of the combustion device 2 to increase the service life of the equipment.

[0032] The combustion device 2 includes: a combustion chamber 21, a gas burner 22, an air outlet 23, an auxiliary component and an inspection component. The combustion chamber 21 is fixedly installed on the left side of the frame 1, the gas burner 22 is fixedly installed on the lower side of the combustion chamber 21, and the air outlet 23 is fixedly installed on the right side of the combustion chamber 21. The end of the air outlet 23 away from the combustion chamber 21 is fixedly connected to the input port of the heat exchanger 4.

[0033] The auxiliary components include: combustion-supporting air ports 24 and air inlets 25. Multiple combustion-supporting air ports 24 are fixedly installed on the lower side of the combustion chamber 21. The horizontal angle between adjacent combustion-supporting air ports 24 is one hundred and twenty degrees. The air inlets 25 are fixedly installed on the rear side of the combustion chamber 21.

[0034] The volatile matter enters the combustion chamber 21 of the combustion device 2 through the air inlet 25, and the gas burner 22 sprays the combustible gas. After being ignited by external equipment, the volatile matter burns in the combustion chamber 21, and the harmful substances are decomposed. After combustion, the high-temperature flue gas in the combustion chamber 21 enters the heat exchanger 4 from the air outlet 23 of the combustion device 2, and then enters the quenching tower 5. The high-temperature flue gas generated by the combustion of the volatile matter is further processed by the combustion chamber 21 and the quenching tower 5, so that the gas emission pollution is reduced, and the temperature of the flue gas entering the quenching tower 5 is reduced.

[0035] The maintenance component includes: a smoke exhaust chimney 26 and an inspection port 27. The smoke exhaust chimney 26 is fixedly installed on the top of the combustion chamber 21. An electric valve is provided in the smoke exhaust chimney 26 for controlling the opening and closing of the smoke exhaust chimney 26.

The inspection port 27 is fixedly installed on the right side of the combustion chamber 21 for inspecting the interior of the combustion chamber 21.

[0036] The combustion-supporting device 3 includes: an oxygen-supplementing air duct 31, an air intake pipe 32, a fan 33, a ring pipe 34 and a branch pipe 35. The upper side of the oxygen-supplementing air duct 31 is fixedly connected to the upper side of the hot fluid output port of the heat exchanger 4, one end of the air intake pipe 32 is fixedly connected to the lower side of the hot fluid output port of the heat exchanger 4, the fan 33 is fixedly installed on the left side of the frame 1, the other end of the air intake pipe 32 is fixedly connected to the output port of the fan 33, the lower side of the oxygen-supplementing air duct 31 is fixedly connected to the ring pipe 34, and each of the combustion-supporting air ports 24 is fixedly connected to a branch pipe 35 at one end away from the combustion-supporting air port 24, and the end of the branch pipe 35 away from the combustion-supporting air port 24 is fixedly connected to the lower side of the ring pipe 34.

[0037] The fan 33 is started to input external air from the air inlet pipe 32 to the hot fluid output port of the heat exchanger 4, absorbing the heat of the heat exchanger 4. After the external air exchanges heat in the heat exchanger 4, its own temperature rises, and at the same time, the flue gas temperature in the heat exchanger 4 drops, thereby reducing the flue gas temperature reaching the quenching tower 5. The heated external air enters the annular pipe 34 through the oxygen supply air duct 31, and then enters the branch pipe 35 through the annular pipe 34. The heated external air in the branch pipe 35 enters the combustion chamber 21 through the combustion-supporting air port 24, thereby increasing the temperature of the external air entering the combustion chamber 21, reducing fuel loss in the combustion chamber 21, and reducing costs.

[0038] Embodiment 2: In some embodiments, as Figure 1-Figure 7 As a preferred embodiment of the present utility model, the vertical cleaning device 6 includes: a cross bracket 61, an injection assembly and a moving assembly. The cross bracket 61 is arranged in the combustion chamber 21, the injection assembly is installed on the middle side of the cross bracket 61, and the two moving assemblies are installed on the left and right sides of the cross bracket 61.

[0039] The moving assembly includes: a rack 62, a first gear 63, a second gear 64, a first bevel gear 65, a second bevel gear 66, a connecting rod 67, a friction block 68 and a spring 69. The rack 62 is fixedly mounted on the left side wall of the combustion chamber 21. The first gear 63 is rotatably connected to the left side of the cross bracket 61 through a rotating shaft. The second gear 64 is rotatably connected to the upper side of the cross bracket 61 through a rotating shaft. The first gear 63 and the second gear 64 are meshed with each other. The first bevel gear 65 is fixedly connected to the front side of the rotating shaft of the first gear 63. The second bevel gear 66 is rotatably connected to the front side of the cross bracket 61 through a rotating shaft, the first bevel gear 65 and the second bevel gear 66 are meshed with each other, the connecting rod 67 is fixedly installed between the rotating shafts of the two first bevel gears 65, and the friction block 68 is slidably connected to the rear side of the cross bracket 61. One end of the friction block 68 is in close contact with the side wall of the second gear 64, so that the rotation of the second gear 64 is damped. The spring 69 is arranged on the friction block 68, one end of the spring 69 is in close contact with the friction block 68, and the other end of the spring 69 is in close contact with the cross bracket 61.

[0040] The spray assembly includes: a fixed plate 610 and a nozzle 611. The two fixed plates 610 are fixedly installed on the middle side of the cross bracket 61. The upper side of the nozzle 611 is rotatably connected to the fixed plate 610. The nozzle 611 is provided with multiple downward nozzles. The input end of the nozzle 611 is fixedly connected to the external high-pressure water supply equipment through a long hose. The components that make up the vertical cleaning device 6 are all high-temperature resistant metal parts.

[0041] When it is necessary to clean the waste residue on the inner wall of the combustion chamber 21, open the inspection port 27, and fix the input end of the nozzle 611 of the injection assembly of the vertical cleaning device 6 to the external high-pressure water supply equipment through a long hose, remove the fixing plate 610, and rotate the nozzle 611 to connect to the fixing plate 610. The fixing plate 610 is installed back on the cross bracket 61. The multiple downward nozzles on the nozzle 611 spray high-pressure flushing liquid to flush the inner wall of the combustion chamber 21 and flush the waste residue on the inner wall of the combustion chamber 21, so that the nozzle 611 moves upward. The upward movement of the nozzle 611 drives the cross bracket 61 to move upward. The upward movement of the cross bracket 61 drives the first gear 63 to rotate. The rotation of the first gear 63 drives the second gear 64 to rotate. The rotation of the second gear 64 is limited by the friction block 68. The second gear 64 has a damping feeling when it rotates, and the second gear 64 rotates slowly. The nozzle 611 rises slowly in the combustion chamber 21. After flushing the combustion chamber 21, the nozzle on the nozzle 611 stops spraying high-pressure flushing liquid, and the vertical cleaning device 6 starts to descend. Since the second gear 64 is restricted by the friction block 68 and always rotates slowly, the vertical cleaning device 6 is always in a slowly descending state. When it descends to the lower side of the combustion chamber 21, the external high-pressure water supply equipment can be started again, so that the nozzle of the nozzle 611 sprays high-pressure flushing liquid for a second flushing until the flushing is completed. After cleaning the waste water in the combustion chamber 21, the nozzle 611 is removed and the inspection port 27 is closed, which is conducive to flushing the combustion chamber 21 multiple times without climbing the combustion chamber 21.
