Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and more specifically, to a multi-layer heat storage chamber RTO structure that can filter dust. Background Technology

[0002] Industrial production processes generate large amounts of waste gas containing harmful substances, requiring effective treatment to meet environmental emission standards. Regenerative Thermal Oxidizers (RTOs), as highly efficient waste gas treatment equipment, play a crucial role in treating organic waste gas. However, in practical applications, traditional RTO equipment presents several problems. In some RTO structures, when waste gas flows through the regenerator chamber, some dust adheres to the surface of the rectangular heat storage element. After prolonged operation, the honeycomb pores of the rectangular heat storage element become clogged with dust, hindering gas flow. Meanwhile, some silica powder is emitted into the atmosphere with the gas, causing pollution and increasing the burden on subsequent treatment stages, even affecting the normal operation and lifespan of the equipment. Furthermore, in some equipment, dust easily accumulates in the heat storage chamber during operation, making cleaning difficult, affecting filtration efficiency, and potentially causing blockages and malfunctions.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] like Figures 1-6 The diagram shows a multi-layer heat storage chamber 1 RTO structure that can filter dust. The structure includes a heat storage chamber 1 and a filter plate 6.

[0017] The heat storage chamber 1 is equipped with multiple layers of uniformly distributed heat storage bodies 3. The heat storage bodies 3 are provided with uniformly distributed through holes to enable them to exchange heat with high-temperature flue gas more efficiently and improve energy utilization efficiency. The heat storage chamber 1 is equipped with a flue gas inlet pipe 4 on the upper side and a flue gas outlet pipe 5 on the lower side. High-temperature gas enters the heat storage chamber 1 from the flue gas inlet pipe 4 and exchanges heat with the heat storage bodies 3 in the heat storage chamber 1 before being discharged from the flue gas outlet pipe 5.

[0018] The upper side wall of the heat storage chamber 1 has two rectangular openings 7 facing each other. The filter plate 6 passes through the openings 7 and is slidably installed above the heat storage body 3. The filter plate 6 has multiple irregular honeycomb perforations 8, which can effectively filter dust in the exhaust gas.

[0019] Each side of the heat storage chamber 1 is provided with a dust removal box 2. The inner wall of the dust removal box 2 is provided with a through-hole 9 that is directly opposite the opening 7 and is the same size and shape. The filter plate 6 passes through the through-hole 9 and enters the dust removal box 2. The dust is blown away by the high-speed fan 16. Half of the filter plate 6 covers the heat storage chamber 1, and the other half of the filter plate 6 is located in the dust removal box 2, so as to realize the alternating use and online cleaning of the filter plate 6.

[0020] As a further improvement, the filter plate 6 is slidably and tightly fitted on the heat storage chamber 1 and the dust removal box 2. A drive motor 10 is provided on one side of the heat storage chamber 1. The output shaft of the drive motor 10 is connected and fixed to the gear 11. A long groove 12 is provided on one side of the filter plate 6. A rack 13 is provided in the long groove 12. The gear 11 meshes with the rack 13. The drive motor 10 drives the filter plate 6 to move laterally through the gear 11, so as to realize the automatic switching and control of the filter plate 6.

[0021] The rack 13 is embedded in the long slot 12, which also ensures a tight fit between the filter plate 6 and the inner wall of the heat storage chamber 1.

[0022] To ensure that the filter plate 6 always has a filtering effect, the filter plate 6 completely covers the heat storage chamber 1. It and the side wall of the heat storage chamber 1 are in sliding seal fit. The filter plate 6 can completely cover the heat storage chamber 1 during and after the lateral movement. Under normal circumstances, the length of the filter plate 6 is slightly more than twice the width of the heat storage chamber 1.

[0023] The filter plate 6 is provided with end plates 14 at both ends and a sealing plate 15 in the middle. The sealing plate 15 and the end plates 14 can completely cover the opening 7 and the through opening 9 and achieve a single-sided seal, ensuring the airtightness of the heat storage chamber 1 and the ash removal box 2.

[0024] Sealing strips are provided on the inner side of end plate 14 and both sides of sealing plate 15. End plate 14 and sealing plate 15, together with the sealing strips, seal the opening 7 and through opening 9 on the right side. Figure 5As shown, the optimal setting position of the sealing plate 15 is as follows: when the right end plate 14 is close to the right side of the through opening 9, the sealing plate 15 is close to the right side of the left opening 7. At this time, the right end plate 14 and the sealing plate 15 seal the heat storage chamber 1, blocking the connection between the heat storage chamber 1 and the dust removal box 2. At this time, the left filter plate 6 is located in the left dust removal box 2 for dust cleaning. After cleaning, the drive motor 10 drives the filter plate 6 to move to the right. The right end of the filter plate 6 enters the right dust removal box 2. The left end plate 14 is close to the outside of the left opening 7, and the sealing plate 15 is close to the left side of the right opening 7.

[0025] The upper part of the dust removal box 2 is equipped with multiple arrays of high-speed fans 16, which are located above the filter plate 6. The lower part of the dust removal box 2 is equipped with a dust discharge fan 17, and the lower part of the dust discharge fan 17 is connected to the dust discharge pipe 18, which improves the dust removal effect and efficiency.
