Description

Technical Field

[0001] This utility model belongs to the technical field of regenerative thermal oxidation devices, specifically relating to a wave-shaped heat storage body installation and arrangement structure. Background Technology

[0002] Because silicon is beneficial for film formation, paints and coatings often contain silicon-containing organic compounds in their formulations. During use, these products release volatile organic compounds (VOCs), polluting the environment and impacting human health. Regenerative thermal oxidizers (RTOs) are a relatively economical way to address VOC emissions and are widely used in industries such as printing and dyeing, coating, and chemicals. The combustion of silicon-containing organic compounds produces SiO2. RTOs typically use ceramic materials such as heat storage bodies, primarily composed of aluminosilicate refractories. Due to the similarity between aluminosilicates and SiO2, SiO2 often adheres to the surface of the heat storage body in a glassy form, clogging its pores and causing excessive pressure drop, thus affecting RTO efficiency. The uppermost layer of the heat storage body in the regenerative chamber is usually the most severely clogged and requires replacement, increasing maintenance costs and necessitating production shutdowns, resulting in significant economic losses. Therefore, in order to improve the service life of the uppermost heat storage body and increase the service life of the regenerative thermal oxidizer, this utility model provides a wave-shaped heat storage body installation arrangement structure. On the one hand, it can guide the SiO2 after combustion to the groove to avoid affecting the heat storage body. On the other hand, it facilitates the overall installation, replacement and cleaning. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, the purpose of this utility model is to provide a wave-shaped heat storage body installation arrangement structure.

[0004] This utility model provides the following technical solution: a wave-shaped heat storage body installation arrangement structure, including an insulation layer, a heat storage body filled in the insulation layer, and a heat storage body arrangement structure arranged on the heat storage body. The heat storage body arrangement structure includes a slotted wave plate one, a saddle ring, and a slotted wave plate two arranged sequentially from top to bottom. Both the slotted wave plate one and the slotted wave plate two are provided with holes, and the holes on the two wave plates are arranged intersectingly to form a set of gaps between the two wave plates and the saddle ring.

[0005] Furthermore, the slotted corrugated plate includes a frame and a set of angle steels arranged along the length of the frame.

[0006] Furthermore, the slotted corrugated plate II includes a frame II and a set of angle steel II arranged along the width direction of the frame II.

[0007] Furthermore, gaps are left between two adjacent angle steels and between two adjacent angle steels.

[0008] Furthermore, both angle steel one and angle steel two are provided with a set of holes arranged along the length direction.

[0009] Furthermore, the insulation layer is provided with mounting nails, and the first frame and the second frame are respectively provided with mounting holes corresponding to the mounting nails.

[0010] Furthermore, both angle steel one and angle steel two have a V-shaped structure.

[0011] Furthermore, the holes are respectively set on the two sides of angle steel one and angle steel two.

[0012] Furthermore, both frame one and frame two are provided with lifting lugs.

[0013] By adopting the above-mentioned technology, the beneficial effects of this utility model compared with the prior art are as follows: 1) In this utility model, the intersecting arrangement of the first and second slit-shaped corrugated plates forms an interlaced airflow channel, which, combined with the flat filling of the saddle ring, constructs a multi-layer slit array. Based on this array design, uniform turbulence can be generated when the airflow passes through, significantly improving the airflow stability. At the same time, the SiO2 particles are guided to the groove of the corrugated angle steel, storing most of the silicates, which makes the RTO furnace body operate stably for a longer time, increases the service life, and reduces the replacement of the heat storage body. The saddle ring is distributed between the first and second slit-shaped corrugated plates, and its arrangement protects the saddle ring from the direct impact of the airflow, thus protecting the life of the saddle ring.

[0014] 2) The structure of this utility model is stable: it is fixed by the inner insulation rock wool support nails, and the mechanism is kept stable by the squeezing action of the support nails and insulation rock wool around the perimeter. 3) Based on the setting of the lifting lugs, this utility model can achieve horizontal and stable placement. The first slotted wave plate uses the saddle ring as support, and the second slotted wave plate uses the original heat storage body as support. The slotted wave plate is designed based on the cooperation of the frame, frame holes and thermal insulation rock wool nails, which makes installation and disassembly very convenient.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0017] Conversely, this utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model as defined in the claims. Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art will fully understand this utility model even without these detailed descriptions.

[0018] Please see Figure 1-7 A wave-shaped heat storage body installation arrangement structure is vertically installed on the top of the heat storage chamber, adjacent to the combustion chamber; it includes an insulation layer 1 and a heat storage body 2 and a heat storage body arrangement structure 3 disposed in the insulation layer 1. The heat storage body arrangement structure 3 is placed on the heat storage body 2 and includes a slotted wave plate 4, a saddle ring 5 and a slotted wave plate 6.

[0019] Specifically, the slotted corrugated plate 4 is located on the top layer, and its frame is fitted into the support nails of the insulation layer 1 insulation rock wool through reserved holes to ensure horizontal flatness; the slotted corrugated plate 6 is located on the bottom layer and is supported by the heat storage body; the middle is filled with a 100mm thick saddle ring 5, and the three form an interlaced airflow channel.

[0020] Specifically, the slotted corrugated plate 4 includes a frame 401, perforated angle steel 402, and lifting lugs 7. The frame 401 supports the angle steel 402, and its dimensions are determined by subtracting the inner insulation rock wool dimensions from the dimensions of the heat storage chamber. The horizontal flatness of the frame 401 is determined by the multi-sided nails on the insulation rock wool. Assembly holes 8 are excavated on the frame 401, and the frame 401 is supported on the nails through the cooperation of the assembly holes 8 and the insulation rock wool nails.

[0021] Lifting lugs 7 are arranged around frame 401 according to its dimensions, with 2 lugs on the long side and 1 lug on the short side. Angle steel 402 with openings inside frame 401 are arranged parallel to each other, with the angle steel 402 parallel to the short side of frame 401. Figure 7As shown, the angle of angle steel 402 is 45 degrees. The unfolded diagram of the perforated angle steel is as follows. Figure 6 As shown, holes are drilled on both sides of the unfolded diagram, with a gap no larger than 2mm. The corner positions correspond to the gas medium inlets (i.e., the lower side). A gap of about 2mm is reserved between adjacent angle steel 402 to guide the airflow and facilitate SiO2 adhesion. Specifically, the slotted corrugated plate 26 includes a frame 2601, perforated angle steel 2602, and lifting lugs 7. The dimensions of the frame 2601 are determined by subtracting the insulation layer thickness from the inner diameter of the heat storage chamber. Two lifting lugs are provided on the long side, and one on the short side, for hoisting and positioning. The angle steel 2602 of the slotted corrugated plate 26 is parallel to the long side of the frame 2601 and is arranged perpendicularly to angle steel 402, forming a multi-level airflow guiding network. This structure further disperses the airflow, enhances the SiO2 adsorption efficiency, and also supports the saddle ring 5.

[0022] Specifically, the corrugated groove structure of angle steel 402 and angle steel 602 effectively captures SiO2 particles. Their pore design ensures turbulence when airflow passes through, promoting SiO2 accumulation in the grooves and preventing vertical impact on the heat storage body. The angle steel material is consistent with the overall structure, offering high temperature resistance and corrosion resistance.

[0023] Specifically, the saddle ring 5 is filled between two corrugated plates. Its irregular shape increases the airflow contact area and works in conjunction with the corrugated plates to form a stable mixed flow, avoiding localized concentration of SiO2. The saddle ring is made of ceramic-based refractory material, which is resistant to high temperatures.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
