Description
Technical Field
[0001] This utility model relates to the field of shaped waste gas treatment technology, and in particular to a shaped waste gas combustion treatment system. Background Technology
[0002] The energy consumption and pollution of setting machines in the textile industry are serious, with exhaust emissions of approximately 2,500 to 6,000 cubic meters per hour. The exhaust gases contain fine fibers from the fabric, dye particles, and oil stains. Direct emission into the air would cause serious environmental pollution, so exhaust gas treatment is necessary.
[0003] Chinese Patent Publication No.: CN 112146112 A, Publication Date: December 29, 2020. This invention proposes a waste gas collection and treatment device for a stenter, including a conveying pipe and an exhaust pipe. The conveying pipe has an L-shaped tubular structure, and from left to right, a gas collection system, a combustion system, a conversion system, a condensation system, a purification system, and an emission system are respectively arranged on the outside of the conveying pipe. The shortcomings of this technical solution are: numerous and complex equipment, high energy consumption, and the pollution caused by the equipment's own emissions contradicts the initial intention of energy conservation and environmental protection in waste gas treatment. Furthermore, the pipe is prone to condensation, with particulate matter adhering to the pipe wall, leading to increased maintenance costs.
[0004] In summary, existing waste gas treatment methods for stenters suffer from high energy consumption, high pollution emissions, and high carbon emissions. Utility Model Content
[0005] The present invention aims to overcome the shortcomings of existing stenter exhaust gas treatment technologies, such as high energy consumption, large pollution emissions, and high carbon emissions, and provides a stenter exhaust gas combustion treatment system that can reduce energy consumption, pollution emissions, and carbon emissions.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A shaped waste gas combustion treatment system includes a workbench, several ovens, a waste gas incinerator, a heat exchanger, a waste heat recovery unit, and an exhaust stack. A burner is installed inside the waste gas incinerator. The ovens and exhaust stack are connected to the upper end of the workbench, while the waste gas incinerator, heat exchanger, and waste heat recovery unit are connected to the lower end of the workbench. The workbench is equipped with a waste gas inlet pipe and a heat recovery pipe, both of which are equipped with a power fan. One end of the waste gas inlet pipe is connected to the oven, and the other end is connected to the heat exchanger. One end of the heat recovery pipe is connected to the oven, and the other end is connected to the waste heat recovery unit.
[0008] An oven and exhaust stack are installed at the upper end of the workbench, while a corresponding waste gas incinerator, heat exchanger, waste heat recovery unit, and power fan are installed at the lower end. Waste gas is transported between the upper and lower parts of the workbench via a waste gas inlet pipe and a heat recovery pipe, saving on waste gas transport path and improving the operating efficiency of the treatment system. The waste gas incinerator has an inlet and an outlet. The heat exchanger is connected to both the inlet and outlet of the waste gas incinerator. The waste gas inlet pipe is connected to the heat exchanger on the side near the inlet of the waste gas incinerator to draw back some heat and use it to heat the waste gas, reducing energy consumption. One end of the waste heat recovery unit is connected to the heat exchanger on the side near the outlet of the waste gas incinerator, and the heat recovery pipe and exhaust stack are both connected to the other end of the waste heat recovery unit. This allows part of the high-temperature gas to be drawn back to the oven through the heat recovery pipe to heat the waste gas and reduce oven energy consumption, while the other part is discharged through the exhaust stack. Compared to traditional waste gas treatment systems, this system reduces the need for electrostatic precipitators, cooling spray equipment, and wastewater treatment, simplifying the system, reducing energy consumption, and achieving energy conservation and carbon reduction. Furthermore, it employs direct combustion to treat the sizing waste gas. Organic molecules, short fibers (cotton, polyester, spandex fibers), and particulate matter in the waste gas are completely decomposed and oxidized (>99% removal rate) in the high-temperature combustion zone (>760℃) after sufficient residence time, generating simple inorganic products such as water and carbon dioxide. The exhaust emissions no longer produce oil fumes or odors, eliminating the regional oil fume and odor problems caused by traditional sizing equipment and alleviating related issues. The existing electrostatic precipitator system typically achieves a 90% removal rate of oil fumes from exhaust gas, but this is significantly affected by temperature and equipment reliability. Frequent shutdowns due to continuous operation and cleaning dead zones result in actual oil fume and particulate matter removal rates falling below design values. This new combustion treatment system utilizes high-temperature direct combustion of exhaust gas. The VOCs, oil fumes, and particulate matter in the shaped exhaust gas originate from the base fabric and are all combustible. The system achieves a pollutant removal rate of over 99%. Furthermore, the system recovers and reuses heat to repeatedly reheat the exhaust gas, further reducing energy consumption and improving processing efficiency. This results in energy conservation, emission reduction, carbon reduction, high operational efficiency, and environmental friendliness through the shaped exhaust gas treatment system.
[0009] Preferably, the waste gas incinerator has a U-shaped structure, with one end serving as the waste gas inlet and the other as the combustion outlet. The heat exchanger has an L-shaped structure, with one end connected to pipe one and the other end connected to pipe two. Pipe one connects to the waste gas inlet, and pipe two connects to the combustion outlet. Both pipes are equipped with fans. The U-shaped waste gas incinerator and the L-shaped heat exchanger form a compact circular path, achieving a highly efficient cycle of waste gas heating-input-combustion heating-output-heat recovery-waste gas heating. Pipe one connects the heat exchanger and the waste gas inlet of the waste gas incinerator to input waste gas for combustion, while pipe two connects the heat exchanger and the combustion outlet of the waste gas incinerator to output the combusted gas. The gas flow is facilitated by the fans within the pipes. This achieves a compact system, economical path, and efficient gas flow.
[0010] Preferably, both pipe 1 and pipe 2 are connected to an insulation structure, which includes an insulation sleeve and an outer shell. The insulation sleeve is fitted onto pipe 1 and pipe 2, and is secured with straps. The outer shell is fitted onto the insulation sleeve and includes an upper shell and a lower shell. The upper shell is connected to a mounting base, and the lower shell is connected to a fixing base. Both the mounting base and the fixing base have fixing holes, into which insert rods are inserted. The insulation sleeve is made of soft insulation material to fit as closely as possible to the surfaces of pipe 1 and pipe 2, thus providing insulation and reducing heat loss. The outer shell protects the insulation sleeve by wrapping it, further providing insulation and protecting it from environmental corrosion. The straps secure the insulation sleeve for easy assembly of the outer shell and for quick maintenance and replacement of the insulation sleeve later. The outer shell is formed by the upper and lower shells. The upper shell is interlocked with the fixing base of the lower shell via the mounting base, and the outer shell is secured by inserting rods into the fixing holes on the mounting base and the fixing base. It achieves the effects of enhancing insulation efficiency, reducing heat loss in pipes 1 and 2, and facilitating assembly, maintenance, and replacement.
[0011] Preferably, the drying oven is equipped with an exhaust gas collection pipe and several pipes (Pipe 3). One end of each pipe (Pipe 3) is connected to the drying oven, and the other end is connected to the exhaust gas collection pipe, which is connected to an exhaust gas inlet pipe. Each drying oven is connected to a corresponding pipe (Pipe 3), through which exhaust gas is collected into an exhaust gas collection pipe. A powered fan is installed inside the exhaust gas inlet pipe, and the fan guides the exhaust gas from the exhaust gas collection pipe into the heat exchanger, thereby increasing the exhaust gas processing capacity and efficiency per cycle. This ensures the processing efficiency of the system.
[0012] Preferably, the oven is equipped with an inlet manifold and several pipes (4). One end of each pipe (4) is connected to the oven, and the other end is connected to the inlet manifold, which in turn connects to a heat recovery pipe. Each oven is connected to a corresponding pipe (4). Waste gas is introduced into a heat recovery pipe through the waste heat recovery pipe and then enters the corresponding oven through the connected pipes (4) to heat the waste gas. A power fan is installed inside the heat recovery pipe, which draws the waste gas in and distributes it through the inlet manifold to ensure that each oven receives heat, thereby increasing the waste gas processing capacity and efficiency per cycle. This ensures the processing efficiency of the system.
[0013] Preferably, the waste heat recovery unit is equipped with an exhaust pipe, and the exhaust stack has an air inlet. One end of the exhaust pipe is connected to the waste heat recovery unit, and the other end is connected to the air inlet. Both ends of the exhaust stack have air outlets, each equipped with an adsorption purification box. The waste heat recovery pipe is connected to the air inlet of the exhaust stack via the exhaust pipe. A powered fan is installed inside the exhaust pipe. Heat enters the exhaust stack through the exhaust pipe and is discharged from both air outlets to improve discharge efficiency. An adsorption purification box is installed at the outlet to adsorb carbon dioxide in the gas before release, thereby reducing the carbon content in the discharged gas. This achieves high-efficiency emissions, improved carbon reduction, and a reduction in the greenhouse effect.
[0014] Preferably, the adsorption purification box is equipped with placement mesh plates and a movable base plate. Several placement mesh plates are provided, and the side walls of the adsorption purification box have vertical grooves and rotating grooves. The placement mesh plates are inserted into the vertical grooves. One end of the movable base plate is connected to a rotating rod, which is inserted into the rotating groove. The other end of the movable base plate is movably connected to the inner wall of the adsorption purification box. The placement mesh plates in the adsorption assembly are inserted into the vertical grooves, ensuring a stable vertical arrangement within the adsorption purification box. This facilitates the even stacking of adsorbent material between the placement mesh plates, allowing for comprehensive and efficient pre-purification of the waste gas. The movable base plate, connected below the placement mesh plates, prevents leakage of adsorbent material. Furthermore, when the adsorption force decreases, the movable base plate allows for rapid discharge and replacement of adsorbent material, ensuring continuous high-intensity adsorption. This achieves the effects of pre-purification of carbon dioxide adsorption, easy replacement of adsorbent material, and continuous high-intensity adsorption.
[0015] Preferably, the inner wall of the adsorption purification box is connected to a positioning strip with a mating groove, and the movable base plate has a matching groove. The movable base plate is embedded in the positioning strip, and the positioning strip is connected to a connecting rod. The connecting rod is fitted with a locking block, which is in contact with the movable base plate. The inner wall of the adsorption purification box is fixed by the mating groove between the positioning strip and the movable base plate, so that the movable base plate is stably embedded in the positioning strip. By rotating the locking block, the movable plate is fixed to ensure the stable placement of the adsorbed material. Rotation can then unlock the movable base plate to quickly discharge waste. This achieves the effect of improving the stability of the structural connection and the convenience of operation.
[0016] Preferably, the adsorption purification box has a feed inlet at the top and a discharge outlet at the bottom. The feed inlet is connected to an upper guide plate, and the discharge outlet is connected to a lower guide plate. Both the feed inlet and discharge outlet are hinged with sealing plates. The adsorption purification box allows material to be fed in through the feed inlet and discharged through the discharge outlet, achieving gravity feeding. The upper guide plate provides a wider inlet and guides the material between the feed inlet and the mesh plate, making feeding faster. The lower guide plate facilitates the collection of waste material, making material replacement more efficient. Both the feed inlet and discharge outlet are sealed with sealing plates. This design improves the efficiency and convenience of material replacement.
[0017] The beneficial effects of this utility model are: achieving energy conservation, emission reduction, pollution reduction, and carbon reduction; high operational efficiency and environmental protection; compact system, economical path, and efficient gas flow; enhanced insulation effect, and easy assembly, maintenance, and replacement; achieving high-efficiency emissions, improving carbon reduction efficiency, and reducing the greenhouse effect; strong adsorption and pre-purification of waste gas, and easy replacement of adsorption materials to achieve continuous high-intensity adsorption; and improving the efficiency and convenience of adsorption material replacement.

Part of the gas is introduced into the intake manifold 22 by the power fan 9 in the heat recovery pipe 8, and then flows back to the oven 1 through various pipes 23 to heat up the exhaust gas. The other part of the gas enters the exhaust stack 6 through the exhaust pipe 24 (at a temperature of 120°C), and is discharged from the exhaust stack 6 into the adsorption purification box 25 connected through the installation port. After being adsorbed by layers of carbon, it is discharged from the exhaust port 46.
[0050] Replacing the adsorbent material: Open the sealing plate 40 at the lower end of the adsorption purification box 25 by rotating the pressure rod 44, and rotate the locking block 35 to open the movable bottom plate 27. Then, the activated carbon will pour out from the discharge port 37 along the movable bottom plate 27 and the lower guide plate 39 under the action of gravity. Close the movable bottom plate 27 again and rotate the locking block 35 to lock it. The lower sealing plate 40 will seal the discharge port 37 through the pressure rod 44. Open the sealing plate 40 at the upper end of the adsorption purification box 25 and pour the new activated carbon along the feed port 36 and the upper guide plate 38 so that the space between each mesh plate 26 is filled with activated carbon adsorbent material. Close the upper sealing plate 40 again to ensure that the adsorption purification box 25 maintains its high-efficiency adsorption capacity for waste gas.
