Description

Technical Field

[0001] The utility model relates to the field of RTO incinerators, in particular to an RTO incinerator waste gas purification device. Background Art

[0002] RTO incinerator is also called regenerative thermal oxidizer. Its principle is to oxidize organic matter in waste gas into corresponding carbon dioxide and water at high temperature, thereby purifying waste gas and recovering the heat released when waste gas is decomposed. Its principle is to heat organic waste gas to above 760 degrees Celsius (specific components depend on the composition) to reoxidize VOC in waste gas into carbon dioxide and water. The high-temperature gas generated by oxidation flows through a special ceramic heat storage body, which heats up the ceramic body and "storages heat". This "heat storage" is used to preheat the organic waste gas that enters later, thereby saving fuel consumption for heating waste gas. However, in the gas diversion structure in the RTO incinerator in the prior art, the gas decomposed by the incinerator is led out through the induced draft fan and then directly discharged into the air, but the gas will carry dust from fuel combustion, which will pollute the surrounding environment.

[0003] The Chinese utility model patent with publication number CN219571949U discloses an RTO incinerator. It mainly filters the dust from the exhaust gas through the first filter and the second filter in the filter box, and then introduces the dust-removed gas into the water tank through the fan for cooling and discharge. However, the filter assembly in the device is not well optimized. In actual use, dust will accumulate at the bottom of the filter. If it is not cleaned in time, the purification efficiency will be greatly reduced. The solution only replaces or maintains the filter assembly after long-term use by setting a handle, which is not convenient to use.

[0004] Therefore, a RTO incinerator exhaust gas purification device is provided to solve the above problems. Utility Model Content

[0029] The cleaning mechanism 7 includes two support frames 71 fixedly mounted on the upper parts of two opposite surfaces of the inner wall of the filter box 3, a reciprocating screw rod 72 is rotatably mounted between the two support frames 71, a driving motor 74 is fixedly mounted on the outer wall of the filter box 3, one end of the reciprocating screw rod 72 passes through the side wall of the filter box 3 and extends to the outside of the filter box 3 and is fixedly connected to the output shaft of the driving motor 74, a slider 73 is screwed on the reciprocating screw rod 72, a support plate 75 is fixedly mounted on the top of the slider 73, a brush plate 77 is mounted on the top of the support plate 75, and the brush surface of the brush plate 77 is arranged in contact with the bottom surface of the filter plate 5.

[0030] In order to facilitate the installation of the driving motor 74 , a motor support plate 741 for supporting the driving motor 74 is fixedly mounted on the outer wall of the filter box 3 , and the driving motor 74 is fixedly mounted on the motor support plate 741 by bolts.

[0031] When in use, the RTO incinerator 2 pressurizes the treated gas through the smoke exhaust pipe 4 and passes it into the filter box 3 for filtering. By starting the drive motor 74, the reciprocating screw rod 72 is driven to rotate, and the reciprocating screw rod 72 drives the slider 73 on its upper portion to reciprocate, and the slider 73 drives the support plate 75 on its upper portion to reciprocate. At the same time, the brush plate 77 connected to the support plate 75 will also reciprocate at the bottom of the filter plate 5, thereby cleaning the dust-receiving surface at the bottom of the filter plate 5 in real time. The dust cleaning work can be completed in real time without taking out the filter plate 5, thereby reducing the dust accumulation at the bottom of the filter plate 5.

[0032] Among them, two symmetrically arranged auxiliary support bars 78 are fixedly installed on two opposite surfaces of the inner side wall of the filter box 3, and the bottom of the support plate 75 is overlapped on the two auxiliary support bars 78. When in use, the support plate 75 is supported by the two auxiliary support bars 78, providing a more stable and reliable sliding support during the reciprocating motion of the support plate 75.

[0033] Furthermore, the top of the filter box 3 is an open design, and a box cover 31 is hinged on the top of the filter box 3, and a door handle 32 is fixedly installed on the top of the box cover 31. When in use, the box cover 31 is opened by the door handle 32, so that the top of the filter box 3 is open, and the filter plate 5 can be directly taken out.

[0034] Furthermore, a lifting member 51 is fixedly installed on the top of the filter plate 5, and the bottom of the filter plate 5 is supported by at least four supporting feet 52 fixedly installed on the inner wall of the filter box 3. When in use, the filter plate 5 can be quickly taken and placed by the lifting member 51, and the filter plate 5 and the filter box 3 are supported by the supporting feet 52.

When in use, the bolts on both sides of the clip 761 are removed to release the fixation of the brush plate 77, and the brush plate 77 is removed from the two groups of clips 761. When installing, the bottom of the brush plate 77 is aligned with the notches of the two clips 761 and placed on the two groups of clips 761. Then, the clip 761 and the brush plate 77 are fixed with bolts, and the installation of the brush plate 77 and the support bar 76 can be quickly completed. The operation is simple and fast.

[0038] When in use, after the cleaning mechanism 7 has worked for a certain period of time, the window door panel 84 is opened, the receiving hopper 81 is stopped at the operation window 83, and the receiving hopper 81 is directly pulled through the pull ring 82 to take out the entire receiving hopper 81, so that the dust in the receiving hopper 81 can be uniformly processed.

[0039] It should be noted that the support plate 75 and the receiving hopper 81 are both trapezoidal structures with an open top, and the optimal opening angle is between 120° and 135°, which can ensure that during the dust cleaning process of the brush plate 77, the fallen dust can be better received and dust spillage can be reduced.
