Compared with traditional catalytic combustion and direct-fired thermal oxidation furnaces (TO), it has the characteristics of high thermal efficiency (≥95%), low operating cost, and the ability to treat large air volume and low-concentration waste gas. When the concentration is slightly higher, it can also perform secondary waste heat recovery, greatly reducing production and operation costs.

The RTO waste gas enters the box body through the air inlet. First, the waste gas is preliminarily filtered through the filter screen to block the larger particles in the waste gas, and then one end of the water guide pipe is connected to the external water source. Under the drive of the pump body, the water source is drawn into the diversion pipe, and then sprayed out by multiple nozzles, the waste gas is sprayed with water to reduce dust, and the fine particles in the waste gas are separated to ensure the filtering effect of the waste gas.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] See also Figure 1-6The utility model provides the following technical solutions: an RTO waste gas treatment device, comprising a box body 1, a water spray dust reduction mechanism 2 is arranged on the box body 1, an air intake pipe 4 is connected to the side wall of the box body 1, a primary filter mechanism 5 is arranged on the box body 1 and located on one side of the air intake pipe 4, a purified air outlet mechanism 6 is arranged inside the box body 1 and located on the side of the water spray dust reduction mechanism 2 away from the primary filter mechanism 5, a filter assembly 7 is arranged at one end of the water spray dust reduction mechanism 2, and a collecting assembly 3 is arranged below the box body 1 and at a position corresponding to the primary filter mechanism 5.

[0025] Specifically, the collecting assembly 3 includes a fixed box 31, a discharge funnel 32, a valve 33, a through hole 34 and a receiving member 35. The through hole 34 is provided on the box body 1 and located below the primary filtering mechanism 5. The discharge funnel 32 is connected to the side wall of the box body 1 and located outside the through hole 34. The discharge funnel 32 is connected to the valve 33. The fixed box 31 is connected to one end of the discharge funnel 32 below the box body 1. The receiving member 35 is provided inside the fixed box 31.

[0026] By adopting the above technical solution, after the primary filter mechanism 5 filters the exhaust gas injected into the intake pipe 4, the larger particle impurities in the exhaust gas fall into the discharge funnel 32 through the through hole 34. When it is necessary to process the impurities inside the discharge funnel 32, the valve 33 is turned to open, and the impurities inside the discharge funnel 32 fall into the receiving part 35 for receiving and collecting operations, and then the receiving part 35 is taken out from the fixed box 31, and then the impurities inside the receiving part 35 are processed, which is convenient for the operator to operate.

[0027] Specifically, the receiving member 35 includes a bottom mesh plate 351, a collection frame 352, a support bar 353, an insertion port 354 and a sealing plate 355. The support bars 353 are connected to both sides of the interior of the fixed box 31. The collection frame 352 is arranged above the support bar 353. The end of the collection frame 352 close to the support bar 353 is connected to the bottom mesh plate 351. The end of the collection frame 352 is connected to the sealing plate 355. The insertion port 354 is arranged on the fixed box 31 at a position corresponding to the sealing plate 355.

[0028] By adopting the above technical solution, the movable sealing plate 355 drives the collection frame 352 to move and plug into the support bar 353 through the plug-in port 354. When the sealing plate 355 is completely in contact with the inner wall of the plug-in port 354, the sealing plate 355 is stopped from moving, so that the bottom mesh plate 351 can be placed inside the fixed box 31. The collection frame 352 and the bottom mesh plate 351 can receive the impurities discharged from the collection funnel 32.

[0029] Specifically, both ends of the sealing plate 355 are provided with grooves, a plug-in rod is inserted into the groove, a connecting spring is connected between the plug-in rod and the groove, and a plug-in groove is provided on the side wall of the fixing box 31 at a position corresponding to the plug-in rod.

[0030] By adopting the above technical solution, the two connecting rods are moved toward each other so that the connecting rods are moved and retracted into the groove, and the connecting rods move to squeeze the connecting spring. After the sealing plate 355 is subsequently moved to fit the inner wall of the plug-in port 354, the connecting rod is released, and the connecting spring loses the external force and returns to its original state, driving the connecting rod to move and be plugged into the plug-in slot. Under the action of the connecting rod, the sealing plate 355 can be limited and fixed to ensure the stability of the sealing plate 355, thereby ensuring the stability of the collection frame 352.

[0031] When this embodiment is used, the RTO exhaust gas is injected into the box body 1 through the air inlet pipe 4, and the exhaust gas is first preliminarily filtered by the primary filter mechanism 5 to block the larger particles in the exhaust gas. The blocked larger particles fall into the discharge funnel 32 through the through hole 34, and then the water spray dust reduction operation is performed to the inside of the box body 1 through the water spray dust reduction mechanism 2, so as to separate the particles of the exhaust gas and perform dust reduction treatment on the fine dust or particles in the exhaust gas. The exhaust gas is purified and discharged through the purification outlet mechanism 6, and the inside of the discharge funnel 32 needs to be cleaned. When the impurities are processed, the valve 33 is turned to open, and the impurities in the discharge funnel 32 fall into the collecting frame 352 and the bottom mesh plate 351 for receiving and collecting. After the impurities are received and collected, the two plug-in rods are moved toward each other so that the plug-in rods are moved and stored in the grooves. Then, the sealing plate 355 is moved toward the periphery of the fixed box 31. The movement of the sealing plate 355 drives the collecting frame 352 to move away from the fixed box 31 through the plug interface 354. Then, the impurities in the collecting frame 352 are processed, which is convenient for the operator to operate.

The filter screen cylinder 73 is connected to one side of the mounting ring 75 and is located inside the built-in ring 71.

[0034] Specifically, the filter assembly 7 further includes a threaded barrel 72 and a threaded groove 74.

[0035] By adopting the above technical solution, the rotating rod is held and force is applied to drive the rotating rod to rotate. The rotation of the rotating rod drives the filter screen cylinder 73 to rotate. The rotation of the filter screen cylinder 73 drives the installation ring 75 to rotate. The rotation of the installation ring 75 drives the threaded cylinder 72 to rotate away from the threaded groove 74, thereby facilitating the disassembly and assembly operation of the filter screen cylinder 73.

[0036] When the present embodiment is in use, the threaded cylinder 72 is moved and inserted into the threaded groove 74, and then the rotating rod is held and force is applied to drive the rotating rod to rotate. The rotation of the rotating rod drives the filter cylinder 73 to rotate, and the rotation of the filter cylinder 73 drives the mounting ring 75 to rotate. The rotation of the mounting ring 75 drives the threaded cylinder 72 to be threadedly connected to the threaded groove 74, so that the filter cylinder 73 can be installed in the water spraying and dust reduction mechanism 2. Subsequently, the external water body is filtered through the filter cylinder 73 and then enters the water spraying and dust reduction mechanism 2 to participate in the water spraying and dust reduction operation, so as to avoid the impurities mixed in the external water body causing the components of the water spraying and dust reduction mechanism 2 to be blocked, thereby affecting the water spraying and dust reduction effect of the water spraying and dust reduction mechanism 2.

The rotation of the brush plate can clean the filter screen and clean the particles on the filter screen, thereby effectively avoiding clogging of the filter screen and ensuring the exhaust gas treatment effect.
