Description

Technical Field

[0001] The utility model relates to the technical field of incinerators, in particular to an RTO heat storage incinerator. Background Art

[0002] The regenerative thermal incinerator is also called the regenerative thermal oxidizer, or "RTO" for short. The principle is to heat the organic waste gas to above 760 degrees Celsius, so that the VOC in the waste gas is oxidized and decomposed into carbon dioxide and water. The high-temperature gas produced by oxidation flows through a special ceramic thermal storage body, which heats up the ceramic body and "storages heat", thereby saving fuel consumption for heating the waste gas. The ceramic thermal storage body should be divided into two or more (including two) zones or chambers, and each thermal storage chamber undergoes the procedures of heat storage-heat release-cleaning in turn, over and over again, and works continuously.

[0003] After the incinerator has been used for a period of time, some dust will accumulate in the filter at the front end of the air inlet pipe. If it is not cleaned in time, it will affect the air intake effect, resulting in low combustion efficiency of the incinerator. In the prior art, manual cleaning of the filter is usually performed regularly, which has low cleaning efficiency and high manual cleaning costs, affecting the use effect. Utility Model Content

[0023] Example:

[0024] Reference Figure 1-Figure 4 , an RTO regenerative incinerator, including an incinerator body 1, and also including: a filter box 2, an air inlet pipe 101 is fixedly arranged on the incinerator body 1, and an air outlet pipe 201 and an air inlet pipe 202 are fixedly arranged at both ends of the filter box 2, the air outlet pipe 201 is detachably connected with the air inlet pipe 101, and the air outlet pipe 201 can be connected to the air inlet pipe 101 by means of a clamp or bolts, preferably by means of bolts, flanges are fixedly arranged on the air inlet pipe 101 and the air outlet pipe 201, the two sets of flanges are fixedly connected by bolts, and a sealing gasket is fixedly arranged between the two sets of flanges, so that when in use, the filter box 2 is convenient The assembly and disassembly of the filter box 2 improves the cleaning efficiency of the filter box 2; a filter bin 203 is opened in the filter box 2, and one end of the air outlet pipe 201 and the air inlet pipe 202 are connected to the filter bin 203, and a filter screen 4 is fixedly arranged in the filter bin 203, and a cleaning plate 301 is lifted and lowered in the filter bin 203, and a brush 302 is fixedly arranged on the cleaning plate 301, and the brush 302 is pressed against the filter screen 4. Here, we set the cleaning plate 301 at one end close to the air inlet pipe 202, that is, the brush 302 is pressed against the windward surface of the filter screen 4, which is convenient for cleaning the dust and impurities intercepted on the filter screen 4.

[0025] When in use, a cleaning plate 301 is lifted and lowered in the filter bin 203, and a brush 302 is fixedly arranged on the cleaning plate 301. During the lifting process of the cleaning plate 301, the dust accumulated on the filter screen 4 can be cleaned to improve the filtering and air intake effects; a slider 501 is slidably arranged in the air outlet pipe 201, and a push plate 5 is fixedly arranged on the slider 501. The slider 501 is fixedly connected to the cleaning plate 301 through a rope 6. When no gas passes through the air outlet pipe 201, the cleaning plate 301 slides downward under the action of gravity, and the brush 302 can automatically clean the filter screen 4, which can reduce the number of manual cleaning times and improve the use effect.

[0026] Reference Figure 3 and Figure 4 A slide bar 3 is fixedly arranged in the filter chamber 203, and the slide bar 3 is preferably symmetrically arranged in two groups, and the two ends of the cleaning plate 301 are slidably connected to the two groups of slide bars 3 respectively. When in use, the cleaning plate 301 can be ensured to slide reliably to prevent it from flipping over and affecting normal use.

[0027] Reference Figure 3 and Figure 4, a cylinder, a hydraulic cylinder or an electric telescopic cylinder can be used to drive the cleaning plate 301 to rise and fall, thereby driving the brush 302 to clean the dust on the filter screen 4. Here, according to the actual use situation, we design the driving mode of the cleaning plate 301 as follows: a limiting groove 204 is opened at the inner top of the air outlet pipe 201, and the long side of the limiting groove 204 is parallel to the axis of the air outlet pipe 201. A slider 501 is slidably arranged in the limiting groove 204, and a push plate 5 is fixedly arranged at the bottom of the slider 501. The push plate 5 has an arc-shaped structure and faces the filter screen 4, so that the gas pushes the push plate 5 to move, and the slider 501 is connected to the cleaning plate 301 through a rope 6; when in use, since the gas intermittently enters the incinerator body 1 for treatment, when in use, when the gas is from the air outlet pipe 201 When the gas flows into the air inlet pipe 101 and enters the incinerator body 1 for processing, the gas can push the push plate 5 to slide in the direction of the air inlet pipe 101. At this time, the slider 501 can pull the cleaning plate 301 to slide upward along the slide rod 3 through the rope 6. When the gas stops being transported, the push plate 5 loses the push of the gas, and then the cleaning plate 301 slides downward under the action of gravity. In this process, the dust flowing down the filter screen 4 after the last filtration can be cleaned with the brush 302. On the one hand, the filter screen 4 can be cleaned in time, and in the cleaning process, since there is no gas flowing through the filter box 2 at this time, the dust can be reduced from gathering on the filter screen 4 again, thereby improving its filtering effect and reducing the impact on the ventilation effect. On the other hand, the number of manual cleaning times can be reduced, the cost of manual cleaning can be reduced, and the use effect can be improved. Here, in order to ensure that the cleaning plate 301 can slide downward reliably, a tension spring is sleeved on the slide rod 3, and the two ends of the tension spring are fixedly connected to the bottom of the slide rod 3 and the bottom of the cleaning plate 301 respectively. When the push plate 5 loses the push of the wind, under the action of the elastic force of the tension spring and gravity, the cleaning plate 301 moves downward reliably with the brush 302, thereby improving the cleaning effect of the filter screen 4.

[0028] Reference Figure 4 , a rotating roller for ensuring the sliding of the rope 6 is rotatably arranged in the filter box 2, and three groups of rotating rollers are arranged at the corners respectively, which can reduce the friction of the corners on the rope 6 and ensure the reliable sliding of the rope 6. The material of the rope 6 is nylon rope, aramid rope or polyester high molecular weight rope. Aramid is a high-strength synthetic fiber with extremely high tensile strength and wear resistance, smooth surface, good flexibility and low elasticity. A rubber sleeve is fixedly arranged in the filter chamber 203, and the rope 6 is passed through the rubber sleeve. The outer wall of the rope 6 is against the inner wall of the rubber sleeve. On the one hand, the dust on the rope 6 can be cleaned, and on the other hand, it has a good sealing effect, which can reduce the flow of gas from the rope 6 to the outlet pipe 201, and improve the use effect.

[0029] Reference Figure 1 and Figure 3A collecting bin 205 is provided in the filter box 2, and a collecting frame 7 is slidably arranged in the collecting bin 205. The collecting bin 205 is connected with the filter bin 203 through a channel, and the collecting bin 205 is located below the filter bin 203. When in use, the dust swept by the brush 302 will enter the collecting bin 205 through the channel, and then fall into the collecting frame 7, which is convenient for cleaning. The bottom of the collecting frame 7 is inclined to facilitate the dust to flow to the end away from the channel, thereby improving the collection effect of the collecting frame 7, and a sealing gasket is fixedly arranged in the collecting bin 205 to improve the sealing effect between the collecting frame 7 and the collecting bin 205 and avoid gas leakage.

[0030] Reference Figure 1 and Figure 3 A rotating shaft 802 is fixedly arranged on the outer wall of the filter box 2, and a baffle 8 is rotatably arranged on the rotating shaft 802. A squeezing pad 801 is fixedly arranged on the inner wall of the baffle 8, and the end face of the squeezing pad 801 away from the baffle 8 is abutted against the outer wall of the collecting frame 7. When in use, by setting the baffle 8 and fixing the squeezing pad 801 on the baffle 8, the collecting frame 7 can be restricted to prevent the collecting frame 7 from slipping out of the collecting bin 205, affecting normal use, and improving the use effect.
