[0032] According to actual waste gas treatment requirement, more than two heat exchange zones 1 can be provided, heat exchange zone 1 is sequentially spliced, and adjacent two heat exchange zones 1 are connected by waste gas connecting air pipe 6 and flue gas connecting air pipe 7, to realize the flow of waste gas and flue gas.

[0033] In the utility model, two heat exchange zones 1 are taken as example to be explained, wherein, the flow direction of flue gas is "front", and flue gas outlet air pipe 3 and air pipe valve group 4 are arranged in heat exchange zone 1 located at front and connected, and combustion zone 5 is arranged in heat exchange zone 1 located at rear.

[0034] When burning silicon-containing organic waste gas, air pipe valve group 4 introduces the waste gas to be burned into heat exchange zone 1 located at front, and the waste gas enters waste gas connecting air pipe 6 from the gap between multiple heat exchange pipes 2 in the heat exchange zone 1, and then reaches combustion zone 5 through the gap between multiple heat exchange pipes 2 in heat exchange zone 1 located at rear for burning, and the temperature of waste gas is increased by heat exchange after passing through two heat exchange zones 1;The flue gas generated after waste gas burning enters multiple heat exchange pipes 2 located at rear in heat exchange zone 1, flue gas connecting air pipe 7 and multiple heat exchange pipes 2 located at front in heat exchange zone 1 in turn, and then is discharged from flue gas outlet air pipe 3. By setting filter mechanism 9, when flue gas passes through filter screen 92, silicon dioxide dust in flue gas can be effectively filtered, to avoid too much dust flowing through heat exchange pipes 2 in next combustion zone 5 and flue gas outlet air pipe 3.

[0035] When the heat exchange pipes 2 need to be cleaned regularly, the back blowing mechanism 8 is started, the back blowing mechanism 8 blows compressed gas to each heat exchange pipe 2 located at the rear, so as to blow away the dust accumulated in the heat exchange pipe 2 and ensure the smoothness of the heat exchange pipe 2; in addition, the knocking assembly 93 is started, so that the inclined filter screen 92 vibrates, the dust attached to the filter screen 92 falls down due to the vibration, and the filter screen 92 is cleaned, so that the filter screen 92 restores the dust filtering function. Compared with the prior art, the ash removal work of the heat exchange pipe 2 does not need to be performed in the heat exchange area 1, the cleaning time is shortened, the labor intensity of workers is reduced, the filter mechanism 9 is provided, the dust in the flue gas is reduced to enter the heat exchange pipe 2, and thus the cleaning cycle of the heat exchange pipe 2 is prolonged.

[0038] In the above, the bag-type dust collector 10 is a prior art, and the specific structure and working principle are not described again. In addition, an induced draft fan can be arranged at the end of the flue gas outlet air pipe 3, so as to draw the flue gas after incineration to the flue gas outlet air pipe 3.

[0039] In a preferred embodiment, referring to Figure 1 The heat exchange pipe 2 is arranged obliquely, and the heat exchange pipe 2 is arranged obliquely upward along the flow direction of the flue gas. When the back blowing mechanism 8 blows the compressed gas into the obliquely arranged heat exchange pipe 2, it is beneficial to the silicon dioxide dust to roll down along the inner wall of the heat exchange pipe 2.

[0040] Specifically, the heat exchange area 1 is provided with a plurality of support plates 21 for fixing the heat exchange pipe 2, and the support plate 21 is provided with a fixing hole for fixing the heat exchange pipe 2. The support plates 21 in each heat exchange area 1 are arranged staggered, and the waste gas meets an obstacle when flowing through the support plate 21 in the heat exchange area 1, and the support plate 21 plays a role of disturbing flow, so that the heat exchange of the waste gas is more sufficient.

[0041] It should be noted that between the two adjacent heat exchange zones 1, the blowback mechanism 8 and the filtering mechanism 9 are connected in sequence to form the flue gas connecting air duct 7, thus the flow direction of the flue gas is: the heat exchange pipe 2 in the rear heat exchange zone 1 - the blowback mechanism 8 - the filtering mechanism 9 - the heat exchange pipe 2 in the front heat exchange zone 1. In order to avoid the exhaust gas entering the flue gas connecting air duct 7, the front end of the rear heat exchange zone 1 and the rear end of the front heat exchange zone 1 are both provided with a sealing wall 11, and the heat exchange pipe 2 is in communication with the sealing wall 11.

The air compressor 83 blows compressed gas into the blow pipe 82, and the compressed gas is sprayed into the corresponding heat exchange pipes 2 through the nozzles 84, so as to blow out the dust accumulated in the heat exchange pipes 2.

[0043] Optionally, the blow pipe 82 is a serpentine pipe, one end of the serpentine pipe is connected with the air compressor 83, and the other end is closed, and all the nozzles 84 are arranged on the serpentine pipe. As Figure 2 shown, the blow pipe 82 can also be a main blow pipe and a plurality of blow sub-pipes in communication with the main blow pipe, the main blow pipe is connected with the air compressor 83, and the plurality of nozzles 84 are arranged on the blow sub-pipes.

[0044] Further, referring to Figure 1 , 2 , the flue gas outlet air duct 3 is connected with a backflow pipe 85, and the backflow pipe 85 is connected with the air compressor 83. Part of the filtered flue gas flows to the backflow pipe 85, and under the action of the air compressor 83, compressed gas is formed, which returns to the silicon-containing organic waste heat storage type combustion furnace under the action of the blowback mechanism 8. Through the above arrangement, the gas environment in the silicon-containing organic waste heat storage type incinerator is avoided to be destroyed by introducing other gas.

[0045] Further, referring to Figure 2The back-blowing mechanism 8 further comprises two second guide rails 86 arranged in the second shell 81 and a second pull-out plate 87 slidably connected with the two second guide rails 86, and the blowing pipe 82 is arranged on the second pull-out plate 87. The two sides of the second shell 81 are respectively provided with second flange rings 811, and the two second flange rings 811 are connected with the heat exchange area 1 and the first shell 91 by fasteners. The fasteners can be bolts and nuts, and the two second flange rings 811 are fixedly connected with the heat exchange area 1 and the first shell 91 by the bolts and nuts.

[0046] In a preferred embodiment, referring to Figure 3 The filtering mechanism 9 further comprises two first guide rails 94 arranged in the first shell 91 and a first pull-out plate 95 slidably connected with the two first guide rails 94, and the filter screen 92 is arranged on the first pull-out plate 95. The knocking assembly 93 is arranged on the lower first guide rail 94. The two sides of the first shell 91 are respectively provided with first flange rings 911, and the two first flange rings 911 are connected with the heat exchange area 1 and the back-blowing mechanism 8 by fasteners. Similarly, the two first flange rings 911 are fixedly connected with the heat exchange area 1 and the second shell 81 by bolts and nuts. The two first guide rails 94 are arranged at the inner top and inner bottom of the first shell 91, so that the first pull-out plate 95 can be pulled out of the first shell 91, and the first pull-out plate 95 can be pulled out without removing the first shell 91, so as to facilitate replacement of the filter screen 92.

[0047] After working for a period of time, a large amount of dust is attached to the surface of the filter screen 92. The knocking assembly 93 is started to make the filter screen 92 vibrate, so as to shake off the dust and restore the filtering ability of the filter screen 92. In actual application, the mesh number of the filter screen 92 on the plurality of filtering mechanisms 9 gradually decreases along the flow direction of the flue gas, so as to ensure the filtering ability of the filter screen 92.

[0048] As shown in the above Figure 5 The knocking assembly 93 is an air hammer. The bottom of the lower first guide rail 94 and the bottom of the first pull-out plate 95 are provided with avoiding holes 951 for avoiding the hammer head of the air hammer. A top rod 952 is vertically and slidably connected in the avoiding hole 951. The air hammer is connected with compressed gas. The compressed gas enters the air hammer to drive the hammer head of the air hammer to move up and down, so as to drive the top rod 52 to act on the filter screen 92. The air hammer can be connected with the air compressor 83 to avoid other gases entering the silicon-containing organic waste gas regenerative combustion furnace.

[0049] It should be noted that the first flange ring 911 of the first housing 91 of the filter mechanism 9 located at the front end is connected to the flue gas outlet duct 3 by fasteners.

[0050] To ensure that during the incineration of waste gas, such as Figure 2 , 3 As shown, to ensure the stability of the first pull-out plate 95 and the second pull-out plate 87, two first screws 20 are provided on both the first housing 91 and the second housing 81, and the first screws 20 are screwed onto the first pull-out plate 95 and the second pull-out plate 87. For disassembly, simply unscrew the corresponding first screw 20 to pull out the first pull-out plate 95 and the second pull-out plate 87. Preferably, the first screws 20 are hand-tightening screws for ease of operation by workers.

[0051] In addition, to facilitate the removal of the first pull-out plate 95 and the second pull-out plate 87, two symmetrically arranged handles 30 are provided on their outer sides.

[0052] In a preferred implementation, see Figure 6 , 7 The first pull-out plate 95 is provided with a first flow equalization plate 96, a second flow equalization plate 97, and a translation component 98. The first flow equalization plate 96 is provided with a plurality of first ventilation holes 961, and the second flow equalization plate 97 is provided with a plurality of second ventilation holes 971. The translation component 98 drives the second flow equalization plate 97 to move, so that all the first ventilation holes 961 and second ventilation holes 971 are staggered or all the first ventilation holes 961 and second ventilation holes 971 overlap. The filter screen 92 is movably disposed on the first flow equalization plate 96. Through the above arrangement, as Figure 6 As shown, during the combustion of exhaust gas, all the first ventilation holes 961 and the second ventilation holes 971 overlap, allowing the flue gas to pass through smoothly; as Figure 7 As shown, when the heat exchange tube 2 is cleaned periodically, the back-blowing mechanism 8 is activated. At this time, the translation component 98 drives the second flow equalization plate 97 to move. All the first ventilation holes 961 and the second ventilation holes 971 are staggered to block the filter screen 92. After the back-blowing mechanism 8 blows out the silica dust accumulated in the heat exchange tube 2, the silica dust slides down the surface of the second flow equalization plate 97 to avoid dust adhering to the filter screen 92 and causing the filter screen 92 to become clogged.

[0053] Specifically, see Figure 4 , 6, 7, the first current sharing plate 96 is provided with a plurality of waist holes 962 extending in horizontal direction, the second current sharing plate 97 is fixed with a positioning nut, the positioning nut is screwed with a second screw 963, the second screw 963 is in sliding connection with the waist hole 962, and the translation assembly 98 is connected with any second screw 963. The translation assembly 98 drives the second screw 963 to move, so as to drive the second current sharing plate 97 to move horizontally, so that all the first ventilation holes 961 and the second ventilation holes 971 are staggered or overlapped with each other.

[0054] Optionally, the translation assembly 98 comprises an electric push rod 981 and a protective cover covering the electric push rod 981, the protective cover is used for protecting the electric push rod 981, so that the silica dust cannot enter the electric push rod 981, thereby prolonging the service life of the electric push rod 981. The extending rod of the electric push rod 981 extends out of the protective cover and is connected with any second screw 963, so as to drive the second current sharing plate 97 to move horizontally.

[0055] Optionally, as shown in Figure 6 , the electric push rod 981 is fixed on the outer wall of the first shell 91, and the extending rod of the electric push rod 981 is detachably connected with a connecting rod 982, the connecting rod 982 extends into the second pull-out plate 87 and is connected with any second screw 963 at the distal end. During operation, the connecting rod 982 is in connection with the extending rod of the electric push rod 981, so as to drive the second current sharing plate 97 to move horizontally; during disassembly, the connecting rod 982 is disconnected from the extending rod of the electric push rod 981, so that the connecting rod 982 can move out of the first shell 91 together with the first pull-out plate 95.

[0056] In the above, referring to Figure 4 , 5 , the side, away from the second current sharing plate 97, of the first current sharing plate 96 is provided with two installation grooves 964 arranged in up-down direction, and the filter screen 92 is arranged in the two installation grooves 964 and can move up and down. The air hammer acts on the bottom of the filter screen 92 through the top rod 952, so as to shake off the silica dust attached to the filter screen 92.

[0057] In a preferred embodiment, referring to Figure 4 , the two sides of the first guide rail 94 located below are respectively provided with dust falling ports 99, and the first shell 91 is slidably connected with a dust collecting box 910 located below the dust falling ports 99. Specifically, the cross section of the dust falling port 99 is in the shape of a funnel, which is conducive to guiding the silica dust shaken off from the filter screen 92 and the silica dust blown out from the heat exchange pipe 2 to fall into the dust collecting box 910 below, and the silica dust is not easy to be raised by the flue gas again. The dust collecting box 910 is used for collecting the silica dust, and when the dust collecting box 910 is pulled out of the first shell 91, the dust collecting box 910 is convenient to clean.

[0058] In conclusion, in the utility model, the waste gas to be incinerated enters the combustion zone 5 through the gaps between the heat exchange pipes 2 in the heat exchange zone 1, and the flue gas generated after incineration is discharged through the multiple heat exchange pipes 2, so as to utilize the heat of the flue gas to increase the temperature of the waste gas to be incinerated. During the discharge of the flue gas, the multiple filter screens 92 filter the flowing flue gas to filter the silicon dust in the flue gas into the heat exchange pipes 2, and in addition, the knocking assembly 93 can be started regularly to shake off the silicon dust adhered to the filter screens 92, so as to ensure the dust filtering capacity of the filter screens 92.

[0059] When the heat exchange pipes 2 need to be cleaned, the air compressor 83 is started, part of the flue gas flowing through the flue gas outlet air pipe 3 enters the air compressor 83 through the backflow pipe 85 to form compressed gas, and the compressed gas blows towards the heat exchange pipes 2 through the multiple nozzles to blow out the silicon dust in the heat exchange pipes 2. At the same time, the translation assembly 98 drives the second flow uniformizing plate 97 to move horizontally, and all the first ventilation holes 961 and the second ventilation holes 971 are staggered with each other to shield the filter screens 92, so that the blown-out silicon dust slides down along the second flow uniformizing plate 97, thereby playing a role in protecting the filter screens 92 and avoiding dust from blocking the filter screens 92. Finally, the falling silicon dust falls into the ash collection box 910 below through the ash falling port 99, so as to realize the unified collection of the dust and facilitate dust cleaning. Compared with the prior art, the staff does not need to enter the equipment to clean the heat exchange pipes 2, which can effectively shorten the working time and reduce the labor intensity of the workers.
