Description

Technical Field

[0001] This utility model belongs to the field of RTO equipment technology, and more specifically relates to an anti-clogging heat storage body. Background Technology

[0002] RTO equipment contains a heat storage chamber that absorbs heat during the treatment of organic waste gas and then uses that heat to preheat new waste gas. However, organic waste gas has a complex composition, and the gas produced during preheating, combustion, and combustion may contain precipitated substances such as ammonium salts and elemental carbon, which adhere to the heat storage body. This can cause blockage of the pores in the heat storage body, affecting the heat absorption and release efficiency of the heat storage unit and thus impacting the normal operation of the RTO equipment.

[0003] Therefore, it is necessary to replace the heat storage medium regularly to ensure the purification effect of organic waste gas. However, at present, the heat storage medium that has been replaced is basically scrapped directly, which is costly. If the blockage material is cleaned and recycled, the cleaning cost will also greatly increase the overall cost, and it will not be more cost-effective than scrapping directly. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a heat storage body consisting of a heat storage main body and an outer sleeve. The detachable outer sleeve is used for adsorption of substances, thereby greatly reducing replacement costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging heat storage body, comprising a heat storage body and an outer sleeve, wherein the outer sleeve is fitted onto the heat storage body, the heat storage body is provided with a plurality of first heat storage through holes, one end of the outer sleeve is an opening, and the other end is a positioning plate, and the opening of the outer sleeve is flush with one end of the heat storage body, the positioning plate abuts against the other end of the heat storage body, the positioning plate is provided with heat storage sleeves corresponding to the first heat storage through holes, the heat storage sleeves extend into the first heat storage through holes, and the outer side of the heat storage sleeves is in close contact with the inner arm of the first heat storage through holes, the heat storage sleeves are provided with second heat storage through holes, and the end of the heat storage sleeves is flush with the opening of the outer sleeve.

[0006] Furthermore, the first heat storage through hole is an inverted conical hole, and the outer surface of the heat storage sleeve is a conical surface corresponding to the conical hole.

[0007] Furthermore, the inclination angle of the inner wall of the conical hole is 0.5 degrees to 2 degrees.

[0008] Furthermore, a positioning groove or positioning protrusion is provided on the end face of the heat storage body that is flush with the outer sleeve, and a corresponding positioning protrusion or positioning groove is provided on the side of the positioning plate away from the heat storage body.

[0009] Furthermore, a through fixing hole is provided on the outer side of the outer sleeve, and a fixing groove corresponding to the fixing hole is provided on the outer side of the heat storage body. A fixing block is provided in the fixing hole, and one end of the fixing block extends into the fixing groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are: when the surface of the outer sleeve and the inside of the second heat storage through hole are blocked, the outer sleeve can be removed and a new outer sleeve can be put on the heat storage body. The replaced outer sleeve is directly scrapped. That is, the outer sleeve replaces the entire heat storage body to attach the substance. The replacement is only the replacement of the outer sleeve made of the same material as the heat absorption body, while the larger heat storage body can continue to be used, thereby greatly reducing the replacement cost.

[0019] Reference Figures 1 to 5 The present invention will be further described below.

[0020] A clog-resistant heat storage body includes a heat storage body 1 and an outer sleeve 2. The outer sleeve 2 is fitted onto the heat storage body 1. The heat storage body 1 is provided with a plurality of first heat storage through holes 3. One end of the outer sleeve 2 is open, and the other end is a positioning plate 4. The opening of the outer sleeve 2 is flush with one end of the heat storage body 1. The positioning plate 4 abuts against the other end of the heat storage body 1. The positioning plate 4 is provided with heat storage sleeves 5 corresponding to the first heat storage through holes 3. The heat storage sleeves 5 extend into the first heat storage through holes 3, and the outer side of the heat storage sleeves 5 is in close contact with the inner arm of the first heat storage through holes 3. The heat storage sleeves 5 are provided with second heat storage through holes 6. The end of the heat storage sleeves 5 is flush with the opening of the outer sleeve 2.

[0021] like Figure 1 As shown, in this example, preferably, the first heat storage through hole 3 is an inverted conical hole, and the outer surface of the heat storage sleeve 5 is the conical surface corresponding to the conical hole.

[0022] Specifically, the inner surface of the first heat storage through-hole 3 and the outer surface of the heat storage sleeve 5 are both smooth surfaces. The two smooth surfaces are in contact with an inclined conical surface to improve the heat transfer efficiency between them. The inner wall of the second heat storage through-hole 6 is a rough surface to improve the heat exchange efficiency with the exhaust gas.

[0023] In addition, the conical hole and conical surface allow the outer sleeve 2 to be fitted onto the heat storage body 1 more accurately and quickly.

[0024] like Figure 3 As shown, in this example, the preferred inclination angle α of the inner wall of the conical hole is 0.5 degrees to 2 degrees, which can be appropriately varied according to the overall volume of the heat storage body.

[0025] In this example, preferably, the end face of the heat storage body 1 that is flush with the outer sleeve 2 is provided with a positioning groove or positioning protrusion, and the side of the positioning plate 4 away from the heat storage body 1 is provided with a corresponding positioning protrusion or positioning groove. When the heat storage bodies are stacked, the positioning is achieved by the cooperation of the positioning groove and the positioning protrusion.

[0026] like Figure 4As shown in the preferred embodiment, the outer surface of the outer sleeve 2 is provided with a through fixing hole 7, the outer surface of the heat storage body 1 is provided with a fixing groove 8 corresponding to the fixing hole 7, a fixing block 9 is provided in the fixing hole 7, and one end of the fixing block 9 extends into the fixing groove 8.

[0027] Specifically, the heat storage body 1 and the outer sleeve 2 are fixed in the axial direction by the fixing block 9. When separating the outer sleeve 2, the fixing block 9 on the side is removed first.

[0028] like Figures 1 to 5 As shown, after the outer sleeve 2 is fitted onto the heat storage body 1, a heat storage body is formed. It is then placed inside the heat storage chamber. When hot gas passes through the outer sleeve 2 and the second heat storage through hole 6 on the outer sleeve 2, it transfers heat to the internal heat storage body 1. When cold gas passes through, it exchanges heat with the heat storage body. The resulting solidified substance will be deposited within the second heat storage through hole 6. When the surface of the outer sleeve 2 and the inside of the second heat storage through hole 6 are blocked, the outer sleeve 2 can be removed, and a new outer sleeve 2 can be fitted onto the heat storage body 1. The replaced outer sleeve 2 is then discarded. That is, the outer sleeve 2 replaces the entire heat storage body to attach the substance. Replacement only requires replacing the outer sleeve 2 with one of the same material as the heat absorption body, while the larger heat storage body 1 is reused, thus greatly reducing replacement costs.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
