Existing desulfurization equipment is generally industrial, unsuitable for civilian and daily use. These devices are costly, bulky, complex in structure, inconvenient to install and disassemble, require frequent professional maintenance and repair, are not compatible with civilian stoves, and are complex and inconvenient to operate. Furthermore, they are costly to use, require advanced automation, and necessitate frequent operation and maintenance by professional personnel.

[0003] Therefore, based on customer feedback regarding the shortcomings of the existing structure, the inventors made further improvements to overcome the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is achieved through the following technical solution: A desulfurization device for a civilian environmentally friendly coal-fired stove, comprising a fixed support, a reaction chamber, and a pull-out tray;

[0006] The fixed bracket is equipped with a reaction chamber, which supports the reaction chamber body. Meanwhile, multiple pull-out trays are installed inside the reaction chamber from top to bottom. The multiple pull-out trays are arranged in an alternating manner inside the reaction chamber and are movably connected to the front and rear side walls of the reaction chamber.

[0007] The reaction chamber has an installation slot on each of its left and right side walls. A fixing structure is provided in the pull-out tray, which includes a toothed column, side column A, and side column B. The toothed column is rotatably set on the lower side of the pull-out tray. Side column A and side column B are respectively set on the upper and lower sides of the toothed column. The side of side column A and side column B opposite to the toothed column has a toothed surface and meshes with the toothed column. By rotating the toothed column, side column A and side column B are moved to the left and right respectively and inserted into the installation slot.

[0008] As a preferred technical solution of this application, the reaction chamber is installed in a fixed bracket. The fixed bracket has feet at the four corners of the lower surface of the fixed plate to support the reaction chamber, and the reaction chamber and the fixed bracket are installed and fixed by snap-fit.

[0009] As a preferred technical solution of this application, the reaction chamber has multiple layers of brackets welded at certain intervals on the left and right side walls. The brackets are made of angle steel or bent parts and are welded together so that multiple pull-out trays are aligned and inserted into the reaction chamber.

[0010] As a preferred technical solution of this application, the plurality of pull-out trays are inserted into the reaction chamber from the front and rear side walls of the reaction chamber and arranged in an alternating manner. At the same time, the tail end of the single-layer pull-out tray is spaced apart from the inner wall of the reaction chamber opposite to it so that the flue gas can pass through smoothly.

[0011] As a preferred technical solution of this application, the pull-out tray includes a tray door, a tray plate and a handle; the tray plate is provided with multiple mesh holes and a tray door is vertically welded to the front end of the tray plate. After the tray plate is inserted into the reaction chamber, the tray door is fixed to the outer wall of the reaction chamber by a snap fastener.

[0012] As a preferred technical solution of this application, the outer surface of the tray door is provided with a handle, which facilitates the insertion and removal of the pull-out tray.

[0013] As a preferred technical solution of this application, the side pillars A and B in the fixed structure are rectangular pillars, one end of which has a toothed surface that meshes with the toothed pillar, and the front end of the toothed pillar extends through the tray door of the pull-out tray. Rotating the end of the toothed pillar causes the meshing side pillars A and B to move and insert into the mounting groove.

[0014] As a preferred technical solution of this application, the uppermost part of the reaction chamber is sealed with a top cover. The top cover is a detachable structure, which facilitates cleaning of the inside of the reaction chamber. At the same time, a flue is vertically arranged in the top cover of the chamber.

[0015] As a preferred technical solution of this application, magnets are provided on the upper and lower sides of the inner side of the tray door, and magnets are also provided on the surface of the reaction chamber that is in contact with the tray door, so as to further fix and seal the container by magnetic attraction.

[0016] This utility model has the following advantages:

[0017] (1) The structure is simple, the device is stable and easy to install and disassemble, and the desulfurization efficiency is good;

[0018] The desulfurization device in this scheme has a relatively simple structure. A reaction chamber is connected to a coal stove via a pipe, and the flue gas generated by the stove or cooking appliances is introduced into the reaction chamber. Inside the chamber, the gas passes through multiple layers of trays from bottom to top. Solid reactants are placed on the mesh trays, and the flue gas reacts with them, effectively absorbing sulfur dioxide and achieving desulfurization. The multi-layered, staggered design of the trays within the reaction chamber ensures smooth gas passage while increasing the gas-solid contact time. Simultaneously, the pull-out trays in this scheme are fixed to the reaction chamber inside the chamber by a fixed structure, and sealed outside the chamber by clips and magnetic attraction, providing double protection for the sealing and fixing effect between the trays and the reaction chamber, preventing flue gas leakage. This scheme has a simple structure and is easy to install and remove, resulting in low operating and maintenance costs and low manufacturing costs. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0027] It should be noted that the orientation or positional relationship indicated by terms such as "left" and "right" is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this invention is usually placed in during use, or the orientation or positional relationship that is commonly understood by those skilled in the art. Such terms are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] Therefore, based on the above issues, please refer to Figure 1 This utility model proposes a desulfurization device for civilian environmentally friendly coal-fired stoves to solve the problem.

[0030] See Figures 1-6 The present implementation plan proposes a desulfurization device for a civil environmentally friendly coal-fired furnace, which includes a pull-out tray 3, a reaction chamber 2, and a fixed support 1 for supporting the reaction chamber 2.

[0031] Among them, see Figure 1 The fixed bracket 1 is set on the ground, and a reaction chamber 2 is installed on the fixed bracket 1. The reaction chamber 2 is a long rectangular cabinet, and the reactant is placed inside to react with the flue gas to treat the sulfur dioxide in the waste gas.

[0032] Among them, see Figures 1-3 Multiple pull-out trays 3 are movably inserted into the reaction chamber 2. These trays 3 are arranged at certain intervals from top to bottom within the reaction chamber 2, with the trays staggered. This multi-layered, staggered arrangement is to increase reaction time and improve desulfurization efficiency. The gap between the single-layer tray and the rear wall is primarily to prevent poor flue gas flow, which could lead to flue gas blockage and backflow, resulting in incomplete fuel combustion, indoor environmental pollution, and safety hazards.

[0033] Among them, see Figure 3 and Figure 6 The reaction chamber 2 is provided with an installation slot 4, and a fixing structure is provided on the underside of the pull-out tray 3. The fixing structure includes a rotatable toothed column 5 and two side columns that mesh with the toothed column 5, namely side column A6 and side column B7. The side columns A6 and B7 have toothed surfaces on the side facing the toothed column 5 and mesh with the toothed column 5. By rotating the toothed column 5, the side columns A6 and B7 are moved to the left and right respectively and inserted into the installation slot 4.

[0034] During operation, coal briquettes are first burned in the coal stove 8 located next to the reaction chamber 2. The resulting high-temperature flue gas containing SO2 enters the reaction chamber 2 from the flue gas inlet at the bottom of the reaction chamber 2. At the same time, the reactant is laid on the pull-out tray 3, and multiple pull-out trays 3 containing reactant are inserted into the reaction chamber 2. After insertion, by rotating the toothed column 5, the two meshing columns on both sides move in the left and right directions and are inserted into the mounting groove 4, which further fixes the trays to the reaction chamber 2, facilitating subsequent work.

[0035] Since current desulfurization devices are typically industrial equipment, they are bulky and inconvenient to install and disassemble, and cannot be used in cooking appliances used by farmers. Therefore, this design proposes a civilian environmentally friendly coal-fired stove desulfurization device. This device utilizes multiple removable trays with mesh panels arranged in layers and staggered within the reaction chamber 2. Reactants are placed on these trays, and flue gas passes through them, reacting with the reactants to effectively absorb sulfur dioxide and achieve desulfurization. The multi-layered staggered design allows for smooth flue gas passage and increases gas-solid contact time, thereby increasing desulfurization efficiency. The entire structure is detachable for easy installation and disassembly. A fixing structure is provided on the trays; the toothed column 5 and side columns work together to further secure the trays to the reaction chamber 2 after insertion, ensuring smooth operation.

[0036] In this embodiment, see Figures 1-3 For reaction chamber 2; multiple pull-out trays 3 are inserted into the internal space of reaction chamber 2 for desulfurization of flue gas. The fixed bracket 1 consists of legs and a fixed plate. Four legs are vertically set at the four corners of the lower side of the fixed plate to support reaction chamber 2 on the ground. At the same time, reaction chamber 2 and fixed bracket 1 are installed and fixed by buckles 13, which facilitates disassembly and installation of the device. Furthermore, at the insertion position of multiple pull-out trays 3 in reaction chamber 2, brackets (protruding long rectangular strips to facilitate precise positioning and insertion of brackets into reaction chamber 2) are provided. The brackets are made of angle steel or bent parts welded together. The brackets allow the pull-out trays 3 to be smoothly positioned into the reaction chamber, which is convenient for installation.

[0037] Furthermore, a coal furnace 8 is installed next to this desulfurization device. By feeding the appropriate briquettes into the coal furnace 8 for combustion, the heat energy generated is utilized. At the same time, a pipe extends from the coal furnace 8, through which flue gas is poured into the lowest air inlet of the reaction chamber 2 and enters the reaction chamber 2 to react with the reactant located on the tray for desulfurization treatment.

[0038] Furthermore, an upper cover 9 is installed at the top of the reaction chamber 2, and the two are sealed together. The upper cover 9 is a detachable structure and is connected to the reaction chamber 2 by means of a buckle 13 or bolts. The detachable structure facilitates cleaning of the inside of the reaction chamber 2. At the same time, a smoke exhaust pipe 10 is vertically installed in the upper cover 9. The smoke exhaust pipe 10 is connected to the upper cover 9 by a flange and is connected to the inside of the reaction chamber, which facilitates the discharge of flue gas to the outside and the smoke exhaust pipe is easy to disassemble.

[0039] In this embodiment, see Figures 2-4 For the pull-out tray 3, the pull-out tray 3 includes a tray door 11, a tray plate, and a handle 12. The tray plate is provided with multiple mesh holes, and a tray door 11 is vertically welded to the front end of the tray plate. After the tray plate is inserted into the reaction chamber 2, the tray door 11 is fixed to the outer wall of the reaction chamber 2 by a buckle 13. Magnets 14 are fixedly provided on the upper and lower sides of the inner side of the tray door 11. At the same time, magnets 14 are also provided on the surface of the reaction chamber 2 that is in contact with the tray door 11. The magnetic attraction between the two further fixes and seals the tray and the reaction chamber 2 to prevent the leakage of flue gas. The handle 12 of the pull-out tray 3 is provided on the outer surface of the tray door 11, which makes it easy to insert and pull out the tray. The whole process is simple, convenient and quick.

[0040] Furthermore, multiple pull-out trays 3 are inserted into the reaction chamber 2 from the front and rear directions through fixed insertion ports, and the pull-out trays 3 are arranged vertically and alternately within the reaction chamber 2. Figure 3 As shown, the tail end of the single-layer pull-out tray 3 is spaced apart from the inner wall of the reaction chamber 2 opposite to it, so that the flue gas can pass through smoothly.

[0041] In this embodiment, see Figure 5 and Figure 6 For the fixed structure, the fixed structure includes a toothed column 5 and side columns A6 and B7; the toothed column 5 rotatably passes through the tray door 11 and is located on the lower side of the tray plate body. The side columns A6 and B7 are rectangular columns, and one end face of each has a toothed surface that meshes with the toothed column 5. The side columns A6 and B7 are located on the upper and lower sides of the toothed column 5, respectively. The rotation of the toothed column 5 can cause the two side columns to move left and right. By rotating the end of the toothed column 5, the meshing side columns A6 and B7 can move and be inserted into the mounting groove 4.

[0042] Furthermore, when the toothed column 5 is rotated to move the side columns A6 and B7 to the left and right respectively, two auxiliary plates are provided on the inner side of the tray door 11. The two auxiliary plates are located on the upper side of the smooth surface of the side column A6 and the lower side of the smooth surface of the side column B7. The auxiliary plates enable the two columns to move only in the left and right directions, and ensure that the support points of the two columns are not only the meshing surface with the toothed column 5, thus preventing the two columns from shifting, falling, or sliding during movement.

[0043] It should be noted that the end of the toothed column 5 extends out of the tray door 11 and is located below the handle 12. When the operator turns the end to the left, the toothed column 5 turns to the left, causing the meshing side column A6 to move to the left and the side column B7 to move to the right, so that they are respectively inserted into the mounting slots 4 on the left and right side walls of the reaction chamber 2. When the operator turns the end to the right, the toothed column 5 turns to the right, at which time the meshing side column A6 moves to the right and the side column B7 moves to the left, so that the side columns A6 and B7 disengage from the mounting slots 4, making it easy to remove the pull-out tray 3.

[0044] It should be noted that when the pull-out tray 3 is pulled out of the reaction chamber 2, the toothed column 5 is rotated to the right, so that the side column A6 and the side column B7 are disengaged from the mounting groove 4 on the left and right side walls of the reaction chamber 2, thereby pulling out the pull-out tray 3. At this time, the fixing structure can be smoothly pulled out of the reaction chamber 2 along with the pull-out tray 3 without collision or obstruction.

[0045] Current desulfurization devices are typically industrial-grade, characterized by high costs (thousands to tens of thousands of yuan), large size, and the need for specialized maintenance. They are unsuitable for civilian stoves, complex to operate, and difficult for rural residents to operate independently. Therefore, there is a need for a civilian desulfurization device that is easy to install, requires no complex tools or components, and allows for rapid installation and disassembly. The desulfurization device in this design is a modular design, composed of multiple components. The overall structure is simple and easy to install. The reaction chamber 2 uses a "fixed bed" structure, i.e., a pull-out tray 3 structure. The tray contains an alkaline reactant that reacts under natural conditions and in the flue gas from coal combustion. Sulfur dioxide undergoes a chemical reaction, absorbing the pollutant in flue gas, reducing sulfur dioxide emissions and environmental pollution. The pull-out tray 3 is connected and fixed to the reaction chamber 2 on the tray door 11 via buckles 13 and magnetic attraction, achieving a sealing effect. At the same time, the inner side of the tray is fixed to the reaction chamber 2 through a fixing structure, namely toothed posts 5 and interactively insertable side posts. The overall structure is very simple, requiring no other tools, and is easy to install, disassemble, and clean. The flue connecting to the reaction chamber 2 is also connected to the reaction chamber 2 via a flange and bolted, facilitating disassembly and cleaning of the inside of the device. The sealing effect of this solution is also relatively good.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
