Description

Technical Field

[0001] The invention relates to filtering equipment, in particular to a vertical activated carbon box for filtering and purifying a water-based paint room. Background Art

[0002] Due to environmental protection requirements, the paint room must be equipped with corresponding air filtration and purification devices. At present, the device is divided into horizontal and vertical structures. The current horizontal structure adopts a drawer-type arrangement. Specifically, the horizontal structure is a frame structure with air inlets and outlets at the front and rear relative positions. Square cavities are arranged in the horizontal and vertical directions in the frame. There are multiple drawer-type structures in the cavity. The drawer-type structure is filled with activated carbon. The gas to be filtered enters the frame from the air inlet and contacts with the activated carbon, and then is discharged from the air outlet. The flow path formed by the gas to be filtered entering the frame is relatively chaotic, and the internal wind pressure is uneven, which greatly affects the filtering effect. The current vertical main structure is to place the filter inlet in the upper position, the filter activated carbon in the inside, and the discharge port in the upper position. The gas to be filtered moves downward from the upper height first, and then moves upward, resulting in a larger wind pressure at the top and a smaller wind pressure at the bottom. There is also a problem of uneven internal wind pressure, which affects the filtering effect. Summary of the invention

[0024] Please refer to Figures 1 to 5 The vertical activated carbon box in the figure mainly designs components such as the air duct 1, the first carbon box 2, the second carbon box 3, and the activated carbon 4. The main design core of the vertical activated carbon box is to design the first carbon box 2 and the second carbon box 3 into a conical structure, so that the gas entering the air duct 1 has a relatively consistent wind pressure at various locations in the air duct 1 in cooperation with the first air inlet 17 arranged along the tangent of the circle on the air duct 1, thus ensuring sufficient contact with the activated carbon 4 and significantly improving the filtering effect. In practical applications, the shape and structure of the above components can be further optimized or other components can be added.

[0025] The wind tube 1 in the figure is a hollow cylindrical structure as a whole, and it is designed with an upper cover plate 11, a shell 12, and a lower cover plate 13 from top to bottom to enclose an internal hollow structure. The upper cover plate 11 and the lower cover plate 13 are located at the upper and lower positions of the shell 12. The upper cover plate 11 is a flat structure, the shell 12 is a hollow cylindrical structure and is divided into two layers, and the lower cover plate 13 is a flat structure. In order to facilitate the filling of activated carbon 4 and unloading, a filling valve 14 can be designed on the upper cover plate 11, and a discharge valve 15 can be designed on the lower cover plate 13. Both valves can be opened and closed manually or electrically. In the figure, multiple filling valves 14 are evenly arranged on the upper cover and are located directly above the cavity between the first carbon box 2 and the second carbon box 3. Correspondingly, multiple discharge valves 15 are evenly arranged on the lower cover and are located directly below the cavity between the first carbon box 2 and the second carbon box 3. The number of filling valves 14 is greater than the number of discharge valves 15. In order to facilitate air intake, a first air inlet 17 can be designed along the tangent direction of the outer shell 12 to be connected with the inner cavity of the outer shell 12 and matched with a first air inlet frame 16, so that the gas entering from the first air inlet 17 can flow into the interior of the wind tube 1 in a spiral shape. The first air inlet frame 16 is a square frame structure extending to the outer wall of the outer shell 12, so as to form an air inlet duct and other components such as induced draft fans and induced draft ducts. In order to increase the amount of air intake, a second air inlet 19 can be designed at a position close to the first air inlet 17 of the outer shell 12 to be connected with the inner cavity of the outer shell 12, and a corresponding second air inlet frame 18 can be matched. The second air inlet 19 is directly aligned with the axial center line of the wind tube 1 toward the axial center line of the wind tube 1, and the second air inlet frame 18 is a directional frame structure extending to the outer wall of the outer shell 12. The first air inlet frame 16 and the second air inlet frame 18 are both located on the lower structure of the shell. In order to facilitate air discharge, a cylindrical air outlet 1 is designed on the upper cover plate 11, and an air outlet 110 is inside the air outlet 1. For later maintenance, a movably openable inspection port 6 can be designed on the housing for easy maintenance.

[0026] The first carbon box 2 in the figure is a hollow conical structure with a flat bottom on both the top and the bottom. It is inverted as a whole to keep the inner wall of the carbon box and the axial center line of the wind tube 1 in an inclined arrangement, that is, the cross-sectional area of ​​the upper part is larger than the cross-sectional area of ​​the lower part. The first carbon box 2 is located inside the wind tube 1 and forms a porous structure to facilitate the flow of air. The overall size of the first carbon box 2, that is, the taper, can be adjusted according to the actual air intake.

[0027] The second carbon box 3 in the figure maintains the same structural design as the first carbon box 2, that is, it is also a conical structure with a flat bottom and a hollow top and bottom. It is inverted as a whole to maintain the inner wall of the carbon box and the axial center line of the wind tube 1 to form an inclined arrangement, that is, the cross-sectional area of ​​the upper part is larger than the cross-sectional area of ​​the lower part. The first carbon box 2 is inside the wind tube 1 and forms a porous structure to facilitate the flow of air. Similarly, the overall size of the second carbon box 3, that is, the taper, can be adjusted according to the actual air intake.

[0028] The second carbon box 3 is located inside the first carbon box 2, and there is a cavity between the two carbon boxes to facilitate filling with activated carbon 4. In order to improve the strength of the carbon box, the horizontal and vertical staggered bracket 5 structure can be fully matched or installed separately.
