Description
Technical Field
[0001] This utility model belongs to the technical field of odor prevention equipment for waste pits in power plants, and specifically relates to an odor prevention chamber for waste pits in waste incineration power plants. Background Technology
[0002] Odor leakage from the waste pits of waste-to-energy plants has always been a major source of odor pollution within the plant area. To prevent odor leakage, the waste pits in waste-to-energy plants are often kept in a sealed environment. Due to operational needs, an odor-proof chamber is often built adjacent to the waste pit. Staff enter and exit the waste pit through this chamber, which serves as a transition zone to prevent odor leakage caused by staff opening the door when entering or leaving the waste pit.
[0003] While existing odor-proof chambers used in waste incineration power plants can prevent odors from directly escaping into the outside air, the exhaust systems used are usually fixed and their positions cannot be flexibly adjusted. This results in the exhaust system taking a considerable amount of time to purify and deodorize the chamber before workers, tools, and vehicles can leave. Consequently, this affects the efficiency of waste disposal operations and fails to fully meet user needs. Utility Model Content
[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing an odor-proof chamber for waste incineration power plants. It not only meets the basic requirements for odor prevention in waste incineration power plants, but also enables rapid and efficient purification of the air in the odor-proof chamber through a mobile odor structure, thereby better meeting people's usage needs.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an odor-proof chamber for a waste incineration power plant waste pit, including an odor-proof chamber body installed at the side of the waste pit. A first inlet / outlet connected to the interior of the odor-proof chamber body is provided at the side of the waste pit, and a second inlet / outlet connected to the outside is also provided at the side of the odor-proof chamber body. A mounting plate is slidably installed on the top of the odor-proof chamber body in a front-to-back direction. A fixing frame is slidably installed on the mounting plate in a left-to-right direction. A telescopic push rod is vertically installed on the fixing frame, and an exhaust hood is installed on the output shaft of the telescopic push rod. Multiple exhaust ports are provided at the bottom and sides of the exhaust hood. A gas purification unit is also installed on the fixing frame, and a flexible air duct is provided between the exhaust hood and the gas purification unit. The exhaust hood and purification unit are connected by the flexible air duct to maintain smooth airflow during operation. An exhaust pump is configured in the inlet pipe to ensure negative pressure operation of the system and prevent odor leakage. The exhaust pipe safely discharges the treated gas. The entire process is closed and controllable, avoiding secondary pollution.
[0006] As a further improvement of this utility model, the gas purification unit includes a purification box mounted on a fixed frame. The purification box is detachably covered. From left to right, the purification box contains a pre-filter, an odor removal filter assembly, and a photocatalytic oxidizer. One end of the purification box is provided with an air inlet pipe connected to the pre-filter. An air pump is installed on the air inlet pipe. The air inlet pipe is connected to the upper end of the air guiding hose. The other end of the purification box is also provided with an air outlet pipe connected to the photocatalytic oxidizer.
[0007] As a further improvement of this utility model, the odor removal filter assembly includes a serpentine filter channel, which is filled with an activated carbon filter layer. A cover plate is detachably provided on the serpentine scraping channel. A first air guide pipe connected to the primary filter is provided at one end of the serpentine scraping channel, and a second air guide pipe connected to the photocatalytic oxidizer is provided at the other end of the serpentine scraping channel.
[0008] As a further improvement of this utility model, the cover is snapped into the purification box, the purification box is provided with a first inlet and outlet, the cover is also provided with a first fixing bolt for screwing and fixing the purification box, and the purification box is provided with a second threaded fixing hole for screwing and fixing the first fixing bolt.
[0009] As a further improvement of this utility model, the cover plate is snapped into the serpentine filter channel, the front end of the serpentine filter channel is provided with a second inlet and outlet, the cover plate is also provided with a compression sealing ring adapted to the serpentine filter channel, the cover plate is also provided with a second fixing bolt for screwing and fixing the serpentine filter channel, and the serpentine filter channel is provided with a second threaded fixing hole for screwing and fixing the second fixing bolt.
[0010] As a further improvement of this utility model, a first handle is also provided on the lid, and a second handle is also provided on the cover plate. The lid and cover plate are respectively provided with a first handle and a second handle, which facilitates the opening and maintenance by the staff; all connecting parts adopt a snap-fit + bolt reinforcement method to ensure sealing and safety while allowing for quick disassembly and assembly.
[0011] As a further improvement of this utility model, the top of the odor-proof chamber body is provided with a first linear slide and a first support slide along the front-to-back direction. A first support slider is slidably arranged in the first support slide. The mounting plate is connected to the slide seat of the first linear slide and the first support slider. The slot of the first support slide and the vertical section of the first support slider are both T-shaped. The bottom of the mounting plate is provided with a second linear slide along the left-to-right direction. The fixing frame is connected to the slide seat of the second linear slide.
[0012] As a further improvement of this utility model, the mounting plate is also provided with a second support slide groove located at the side end of the second linear slide table. A second support slider is slidably disposed in the second support slide groove. The slot of the second support slide groove and the vertical cross section of the second support slider are both T-shaped. The fixing frame is also connected to the second support slider.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, by setting up a three-stage purification system consisting of a pre-filter, an odor-removing filter, and a photocatalytic oxidizer, harmful components such as dust particles, organic pollutants (such as VOCs), hydrogen sulfide, and ammonia in the odorous air can be removed step by step. The pre-filter prevents large particles from clogging subsequent units; the activated carbon layer efficiently adsorbs odor molecules; and the photocatalytic oxidation further decomposes residual gaseous pollutants, achieving deep purification, resulting in cleaner exhaust air that meets environmental protection requirements.
[0014] Secondly, the top of the odor-proof chamber is equipped with a first linear slide and a first support slide in the front-to-back direction, which, together with a second linear slide and a second support slide in the left-to-right direction, allows the mounting plate and fixing frame to slide in two dimensions in the horizontal plane. Combined with the telescopic push rod that drives the extraction hood to move up and down, a three-dimensional adjustable structure is formed, which can precisely control the position of the extraction hood, fully cover the garbage pit entry and exit operation area, and improve the odor capture efficiency.
[0015] Third, the exhaust hood is equipped with multiple exhaust ports at the bottom and sides, which can quickly collect high concentrations of odor from different directions; with the sliding mechanism, the exhaust point can be dynamically adjusted according to the actual working conditions, which is especially suitable for the instantaneous pollution peaks generated when personnel or vehicles frequently enter and exit, realizing the proactive prevention and control mode of "extracting odor from wherever it is present".
[0016] Fourth, the purification box adopts a detachable lid, which is fixed by handles and bolts, making it easy to open for maintenance or replacement of internal components; the odor removal filter component adopts a serpentine filter channel structure, which extends the gas residence time and improves adsorption efficiency; the serpentine channel is equipped with a detachable cover plate and sealing ring, which supports individual disassembly and cleaning or replacement of activated carbon filler without the need to disassemble the entire equipment, reducing maintenance costs and downtime.
[0017] Fifth, the first and second support slides and sliders all adopt a T-section design, which makes the structure stable, has strong resistance to eccentric loads, and is not easy to loosen or jam during long-term operation, thus ensuring the safety and durability of the moving parts under frequent operation.

An exhaust hood 204 is disposed on the output shaft of the telescopic push rod 203. Multiple exhaust ports 205 are disposed on the bottom and side of the exhaust hood 204. A gas purification unit is also disposed on the fixing frame 202. A gas guiding hose 206 is disposed between the exhaust hood 204 and the gas purification unit. The air extraction hood 204 is connected to the purification unit via the air guide hose 206 to maintain smooth airflow during operation; the air inlet pipe 211 is equipped with an air pump 212 to ensure negative pressure operation of the system and prevent odor from leaking out; the air outlet pipe 213 safely discharges the treated gas. The entire process is closed and controllable, avoiding secondary pollution.
[0023] like Figure 2 , 4 As shown in Figure 5, the gas purification unit includes a purification box 207 mounted on a fixed frame 202. A box cover 208 is detachably mounted on the purification box 207. From left to right, the purification box 207 contains a pre-filter 209, an odor removal filter assembly, and a photocatalytic oxidizer 210. One end of the purification box 207 is provided with an air inlet pipe 211 connected to the pre-filter 209. An air pump 212 is mounted on the air inlet pipe 211. The air inlet pipe 211 is connected to the upper end of the air guide hose 206. The other end of the purification box 207 is also provided with an air outlet pipe 213 connected to the photocatalytic oxidizer 210.
[0024] like Figure 4 , 5 As shown, the odor removal filter assembly includes a serpentine filter channel 214, which is filled with an activated carbon filter layer. A cover plate 215 is detachably provided on the serpentine scraping channel. A first air guide pipe 216 connected to the pre-filter 209 is provided at one end of the serpentine scraping channel, and a second air guide pipe 217 connected to the photocatalytic oxidizer 210 is provided at the other end of the serpentine scraping channel.
[0025] like Figure 2 , 3As shown, the top of the odor-proof chamber body 102 is provided with a first linear slide 401 and a first support slide 402 along the front-to-back direction. A first support slider 403 is slidably disposed in the first support slide 402. The mounting plate 201 is connected to the slide seat of the first linear slide 401 and the first support slider 403. The slot of the first support slide 402 and the vertical section of the first support slider 403 are both T-shaped. The bottom of the mounting plate 201 is provided with a second linear slide 404 along the left-to-right direction. The fixing frame 202 is connected to the slide seat of the second linear slide 404.

A second support slider 406 is slidably disposed in the second support slide groove 405. The slot of the second support slide groove 405 and the vertical section of the second support slider 406 are both T-shaped. The fixing frame 202 is also connected to the second support slider 406.
[0027] After a user opens the first entrance / exit 103 to enter or leave the garbage bin 101, before opening the second entrance / exit, they can first connect the power supply and turn on the air extraction pump 212 in the gas purification unit. The entire system operates under negative pressure to prevent odor leakage. Then, the control system drives the slide of the first linear slide 401 to move back and forth, and under the support and sliding guidance of the first support slider 403 and the first support groove 402, it drives the mounting plate 201 and the fixing frame 202 to move in the back-and-forth direction; it can also drive the slide of the second linear slide 404 to move left and right, and under the support and sliding guidance of the second support slider 406 and the second support groove 405, it drives the mounting plate 201 and the fixing frame 202 to move in the left and right direction; simultaneously, the extension length of the telescopic push rod 203 can be adjusted to control the up-and-down movement of the extraction hood 204, achieving precise positioning in three-dimensional space, bringing the extraction hood 204 closer to the odor source.
[0028] Multiple exhaust ports 205 located at the bottom and sides of the exhaust hood 204 can efficiently capture emitted odors from different angles. Under the action of the exhaust pump 212, the odor enters the air inlet pipe 211 of the purification chamber 207 through the air guide hose 206, and then flows into the pre-filter 209, which first removes large particles of dust and impurities from the odor to protect the subsequent purification components; then it enters the serpentine filter channel 214 through the first air guide pipe 216, where the gas has a longer residence time in the tortuous path, fully contacting the activated carbon filter layer and adsorbing odor molecules (such as hydrogen sulfide, ammonia, etc.); the purified gas enters the photocatalytic oxidizer 210 through the second air guide pipe 217, where the catalyst (such as titanium dioxide) generates highly oxidizing free radicals under ultraviolet light irradiation, decomposing residual organic pollutants into harmless carbon dioxide and hydrogen peroxide.
[0029] The clean air, after three stages of treatment, is discharged outdoors through the exhaust pipe 213 or recycled to ensure that emissions meet standards and avoid secondary pollution.
[0030] According to another embodiment of the present invention, such as Figure 2 , 4 As shown, the cover 208 is snapped into the purification box 207. The purification box 207 is provided with a first inlet and outlet. The cover 208 is also provided with a first fixing bolt 218 for screwing and fixing the purification box 207.

The serpentine filter channel 214 is provided with a second threaded fixing hole that is screwed into the second fixing bolt 220.
[0032] like Figure 2 , 4 As shown in Figure 5, a first handle 301 is provided on the cover 208, and a second handle 302 is provided on the cover plate 215. The cover 208 and the cover plate 215 are respectively provided with a first handle 301 and a second handle 302 to facilitate the opening and maintenance by the staff; each connection part adopts a snap-fit + bolt reinforcement method to ensure sealing and safety while quickly disassembling and assembling.
[0033] Simply separate the second fixing bolt 220 from the second threaded fixing hole and release the fixing at the connection between the cover 208 and the purification box 207, and the cover 208 can be removed through the second handle 302; then separate the first fixing bolt 218 from the first threaded fixing hole and release the fixing at the connection between the cover plate 215 and the serpentine purification channel, and then remove the cover plate 215 through the first handle 301, and then the activated carbon filter layer can be disassembled and replaced.
[0034] After the new active filter layer is installed into the serpentine filter channel 214, the cover plate 215 can be snapped into the serpentine filter channel 214. Then, the first fixing bolt 218 is connected to the first threaded fixing hole to fix the cover plate 215 and the serpentine filter channel 214 together. The sealing ring 219 is used to make the connection between the cover plate 215 and the serpentine filter channel 214 have a significant sealing performance. After that, the box cover 208 can be snapped into the purification box 207. Then, the second fixing bolt 220 is connected to the second threaded fixing hole to fix the box cover 208 and the purification box 207 together.
[0035] In another embodiment, the fixing frame 202 is also provided with a guide tube located at the side end of the telescopic push rod 203, and the air extraction hood 204 is also provided with a guide rod that is inserted into the guide tube.
