Description

Technical Field

[0001] This utility model relates to a device for removing odors from exhaust gas in cigarette production, and more particularly to a spray ring for degrading odors at the ventilation exhaust outlet of a cigarette workshop. Background Technology

[0002] The tobacco processing workshops of cigarette manufacturing enterprises have stringent requirements for environmental temperature and humidity. During normal production, these conditions must be maintained at a relatively high level. The workshop roof is equipped with numerous ventilation and exhaust fans and exhaust stacks leading directly to the outside. These ventilation fans are periodically activated to expel the hot air from the workshop through the exhaust stacks. The open top of the exhaust stack forms the exhaust vent, and an umbrella-shaped rain cap is installed above the vent. The air from the workshop diffuses downwards and outwards through the gap between the exhaust vent and the edge of the rain cap. During normal production, the air contains tobacco dust and odors, which are discharged outdoors along with the hot air through the exhaust stacks, causing some environmental pollution and affecting the surrounding residents with unpleasant odors. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a spray ring for odor degradation at the ventilation exhaust vent of a cigarette workshop, which sprays a mist of agent into the gas discharged from the exhaust vent of the exhaust pipe to achieve odor degradation of the discharged gas.

[0004] This utility model is achieved through the following technical solution:

[0005] A spray ring for odor degradation at the ventilation exhaust vent of a cigarette manufacturing workshop is disclosed. The workshop has an exhaust pipe at the top with an open top forming an exhaust vent. A rain cap is installed above the exhaust vent. The exhaust pipe is detachably fitted with a spray ring. The spray ring has multiple spray nozzles spaced circumferentially on it. Nozzles are installed at the spray nozzles, and the nozzles spray outward at an angle along the top of the spray ring. The spray ring has a pipe inlet for connecting to a main pipe for supplying a spray source.

[0006] As a preferred embodiment of the above-mentioned spray ring, at least two fastening nuts are distributed circumferentially on the spray ring. The axial direction of the fastening nuts extends radially along the spray ring. The fastening nuts are screwed into the fastening nuts from the outside to the inside by the rod end of the fastening bolt and pressed against the outer wall of the exhaust pipe, so as to realize the detachable installation of the spray ring and the exhaust pipe.

[0007] As a preferred embodiment of the above-mentioned spray ring, the spray ring is formed by joining two spray half-rings together, with the ends of the two spray half-rings detachably connected together.

[0008] As a preferred embodiment of the above-mentioned spray ring, each end of the spray half-ring is provided with a fixing plate, and the fixing plate has a waist-shaped hole. The fixing plates at both ends of the two spray half-rings are fitted together in a corresponding manner, and the two fixing plates are locked together by passing screws through the waist-shaped holes on the two fitted fixing plates and tightening nuts.

[0009] As a preferred embodiment of the above-mentioned spray ring, the upper half of the spray ring is provided with five spray nozzles, and the bottom of the spray ring is provided with three fastening nuts.

[0010] As a preferred embodiment of the above-mentioned spray ring, a pipe inlet is provided at the bottom of the spray semi-ring.

[0011] This invention has the following advantages over the prior art:

[0012] This invention provides a spray ring for odor degradation at the ventilation exhaust vents of cigarette manufacturing workshops. By installing a spray ring around the periphery of the exhaust pipe, multiple nozzles distributed circumferentially on the spray ring tilt upwards and outwards to spray a mist of odor-degrading agent. This agent comes into contact with the gas exiting from the exhaust vent at the top of the exhaust pipe, effectively reducing the odor concentration in the final exhaust gas. Furthermore, the height of the spray ring on the exhaust pipe can be adjusted to ensure that the nozzles are at a suitable height, guaranteeing accurate spray positioning and thus ensuring effective odor degradation of the exhaust gas.

[0017] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0018] See Figures 1 to 3This embodiment discloses a spray ring for odor degradation at the ventilation exhaust vent of a cigarette workshop. The top of the cigarette workshop is equipped with an exhaust pipe 1, with an open top forming an exhaust port 2. A rain cap 3 is provided above the exhaust port 2 of the exhaust pipe 1. A spray ring is detachably fitted around the exhaust pipe 1. The spray ring has multiple spray ports spaced circumferentially. A nozzle 4 is installed at the spray port. The nozzle 4 is a high-pressure resistant nozzle. The spray direction of the nozzle 4 is to extend outward at an angle along the top of the spray ring. The spray ring is equipped with a pipe inlet 5, through which a spray source delivery pipe is connected.

[0019] At least two fastening nuts 6 are distributed circumferentially on the spray ring. The axial direction of the fastening nuts 6 extends radially along the spray ring. The fastening nuts 6 are screwed into the fastening nuts 6 from the outside to the inside through the rod end of the fastening bolt and pressed against the outer wall of the exhaust pipe 1, so as to realize the detachable installation of the spray ring and the exhaust pipe 1.

[0020] To facilitate the installation of the spray ring on the exhaust pipe 1, the spray ring is designed as a split structure. The spray ring is formed by joining two spray half-rings 7 together, with the ends of the two spray half-rings 7 detachably connected together. Each end of the spray half-ring 7 is provided with a fixing plate 8, and the fixing plate 8 has an oblong hole 9. The fixing plates 8 at both ends of the two spray half-rings 7 are fitted together one-to-one, and the two fixing plates 8 are locked in place by screws passing through the oblong holes 9 on the two fitted fixing plates 8 and tightening nuts.

[0021] In this embodiment, each spray half-ring 7 has five spray nozzles on its upper half, three fastening nuts 6 on its bottom, and a pipe inlet 5 on its bottom. Thus, the spray ring formed by two spray half-rings 7 has a total of ten spray nozzles, six fastening nuts 6, and two pipe inlets 5 arranged circumferentially on its surface.

[0022] During installation, two spray semi-rings 7 are placed around the exhaust pipe 1 to form a complete ring. The ends of each fastening bolt are screwed into the fastening nuts 6 from the outside to the inside, and then pressed against the outer wall of the exhaust pipe 1 to achieve a locked installation between the spray semi-rings 7 and the exhaust pipe 1. Then, the pipe inlets 5 at the bottom of each spray semi-ring 7 are connected to the spray source delivery main pipe. The spray source delivery main pipe delivers the odor-removing agent to the spray semi-rings 7, and the atomized agent is sprayed upwards through the nozzles 4 around the spray semi-rings 7. This atomized agent mixes thoroughly with the gas discharged from the exhaust port 2 at the top of the exhaust pipe 1, thereby degrading the odor in the gas and effectively reducing the odor concentration in the final discharged gas.

[0023] In this embodiment, the spray ring is detachably installed on the exhaust pipe 1 by screwing the end of the fastening bolt into the fastening nut 6 and pressing it against the outer wall of the exhaust pipe 1. Loosening the fastening bolts allows adjustment of the height of the spray ring on the exhaust pipe 1, ensuring that the nozzle 4 on the spray ring is at a suitable height, thus ensuring the accuracy of the spray position and consequently ensuring the odor degradation effect on the exhaust gas.

[0024] The above are merely preferred embodiments of the present utility model and are 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.
