Description

Technical Field

[0001] The utility model relates to the technical field of odor treatment devices, in particular to a workshop odor removal device. Background Art

[0002] The waste gas pollution factors in the refining workshop are hydrogen sulfide, ammonia, odor, styrene, non-methane total hydrocarbons, n-hexane, VOCs, oil mist, and particulate matter. There are both acidic and alkaline waste gases, organic waste gases, other malodorous gases, as well as oil mist and particulate matter, with complex components.

[0003] The waste gas is first washed with water to absorb malodorous gases such as hydrogen sulfide and ammonia that are easily soluble in water; after water washing, it enters the AOP advanced oxidation stage. This technology uses a micro-nano bubble generator to inhale ozone at one end and prepared hydrogen peroxide at the other end, and generates bubbles below 400 nanometers through a water distributor. During this process, due to the characteristics of micro-nano bubbles and the synergistic effect of ozone and hydrogen peroxide, the malodorous substance molecules and VOCs are dissociated and excited under the bombardment of ozone, and the substances are decomposed and transformed into harmless components such as CO2 and H2O; after the waste gas is deeply oxidized, it enters alkali washing to absorb the residual pollutants.

[0004] Because the VOCs concentration in the refining waste gas is relatively high, and the emission requirements are more stringent than the waste gas emission standards. In order to ensure that the non-methane total hydrocarbon VOC ≤ 30 mg / m3 emission requirement is met, an injection type plasma device is added before alkali washing, and activated carbon adsorption treatment is carried out after the alkali washing tower. The activated carbon needs to be stored in a carrier frame, resulting in only the gas flowing through the air flow channel being able to contact the activated carbon, with a small contact area with the activated carbon and a small adsorption capacity for the waste gas. Therefore, we propose a workshop odor removal device to solve the existing problems. Content of the Utility Model

[0005] The purpose of the utility model is to propose a workshop odor removal device for the problems existing in the background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A workshop odor removal device, including a bottom plate, a cylinder body, a motor, a mounting cylinder, and a grid cylinder.

The gear meshes with the toothed ring.

[0007] Preferably, brackets are provided at both the intake pipe and the lower end of the mounting shaft, and the lower ends of the brackets are connected to the bottom plate. The brackets support the intake pipe and the mounting shaft, realizing the fixation of the cylinder body above the bottom plate.

[0008] Preferably, a maintenance door is provided at the upper end of the cylinder body, and the maintenance door is rotatably inserted and fixed to the cylinder body by bolts. When maintaining and replacing the activated carbon inside the cylinder body, enter the inside of the cylinder body through the inspection door.

[0009] Preferably, the sleeves are all rotatably inserted inside the rotating seat, and one end of the intake pipe is connected to the rotating seat through penetration. The gas input by the intake pipe directly enters the inside of the sleeve, and then enters the inside of the installation cylinder.

[0010] Preferably, a second support net is provided inside the installation cylinder, and a first support net is provided on the inner wall of the grid cylinder. The first support net and the second support net support the activated carbon. While ensuring the effective passage of gas through the support nets with small gaps, the outflow of activated carbon is avoided due to the large-diameter grid plates and through holes.

[0011] Preferably, a storage opening is provided inside the upper end of the grid cylinder, a plug plate is provided inside the upper end of the storage opening, and symmetrically distributed handles are provided on the upper end of the plug plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The present utility model carries the activated carbon particles through the storage cavity between the installation cylinder and the grid cylinder. After the waste gas is transported into the installation cylinder, the gas can contact the activated carbon at any position except for the two opposite ends, showing an annular distribution of the activated carbon, which increases the contact area with the waste gas. When filtering and removing odors from the waste gas with the same floor area of the filtering equipment, the flow rate of the waste gas treatment increases, improving the odor purification effect on the waste gas.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0021] As Figures 1 - 4 shown, a workshop odor removal device proposed by the present utility model includes a bottom plate 1, a cylinder body 2, a motor 9, a mounting cylinder 12 and a grid cylinder 16. A cylinder body 2 is arranged above the bottom plate 1, an inspection door 5 is arranged at the upper end of the cylinder body 2, and the inspection door 5 and the cylinder body 2 are rotationally inserted and fixed by bolts. An installation cylinder 12 is arranged inside the cylinder body 2. One end of the intake pipe 6 is connected to the rotating seat 14 through penetration. Through holes 21 distributed in an annular array are formed inside the installation cylinder 12. A grid cylinder 16 is sleeved on the outer wall of the installation cylinder 12. An annular storage cavity 17 is arranged between the grid cylinder 16 and the installation cylinder 12. A support net two 22 is arranged inside the installation cylinder 12. A support net one 20 is arranged on the inner wall of the grid cylinder 16. A storage port 18 is formed inside the upper end of the grid cylinder 16. A plug plate 15 is arranged inside the upper end of the storage port 18. Symmetrically distributed handles 19 are arranged on the upper end of the plug plate 15. A flow guide cover 7 is penetrated and installed at the upper end of the cylinder body 2, and an exhaust pipe 8 is penetrated and installed at the upper end of the flow guide cover 7.

[0022] Based on the implementation steps of Embodiment 1: The waste gas is transported to the inside of the installation cylinder 12 through the intake pipe 6. The waste gas flows outward inside the installation cylinder 12. The activated carbon inside the annular storage cavity 17 comes into effective contact with the flowing waste gas, adsorbing the harmful substances inside the waste gas. When the waste gas passes through the grid cylinder 16, it is output through the flow guide cover 7 and the exhaust pipe 8. The gas flowing in multiple directions is adsorbed by the activated carbon. The activated carbon distributed in an annular shape has a large adsorption area. When used in waste gas purification equipment with the same floor area, the purification flow rate of the waste gas is increased.

[0023] As Figures 1 - 4As shown in the figure, a workshop odor removal device proposed by the present utility model, compared with the first embodiment, this embodiment further includes: an air inlet pipe 6 is provided at one end of the cylinder body 2, an installation shaft 4 is provided at one end of the cylinder body 2, brackets 3 are provided at both the air inlet pipe 6 and the lower end of the installation shaft 4, and the lower ends of the brackets 3 are connected to the bottom plate 1. Both ends of the installation cylinder 12 are provided with sleeves 13. Rotating seats 14 are embedded and installed inside both ends of the cylinder body 2. The sleeves 13 are rotatably inserted into the inside of the rotating seats 14. A gear ring 11 is sleeved on the outer wall of the sleeve 13. A motor 9 is provided on one inner wall of the cylinder body 2, and a gear 10 is provided at one end of the motor 9. The gear 10 meshes with the gear ring 11.

[0024] In this embodiment, when the motor 9 operates to drive the gear 10 to rotate, the gear 10 pushes the gear ring 11, thereby driving the installation cylinder 12 to rotate. During the use of the activated carbon, due to gravity, it will be pressed downward, reducing the internal gap of the activated carbon and the resistance when the waste gas passes through. By rotating the installation cylinder 12, the activated carbon inside the storage cavity 17 flows under the action of the rotational force, avoiding excessive accumulation of the activated carbon and ensuring the effective passage of the waste gas.
