DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, specific embodiments of the present disclosure will be described clearly and completely below with reference to the drawings. These embodiments are provided only by way of example. Obviously, the described embodiments are part of, rather than all of, the embodiments of the present disclosure. Based on the described embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative effort fall within the scope of the present disclosure.

[0032] In the description of the present disclosure, it should be noted that the terms “center”, “longitudinal”, “transverse”, “length”, “width”, “thickness”, “upper”, “lower”, “front”, “rear”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inner”, “outer”, “clockwise”, “counterclockwise”, “axial”, “radial”, “circumferential” and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present disclosure and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present disclosure.

[0033] In the description of the present disclosure, unless explicitly specified and limited, the terms "set", "install", "connect", "connect", "fix" and other terms should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected; it can be mechanically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances. In addition, the terms "first", "second" and the like are for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features.

[0034] One embodiment of the present disclosure provides a detachable gas filtering device. Referring to Figures 1-10 , the detachable gas filtering device comprises a shell, an outer cylinder assembly 4 and an inner cylinder assembly 8. The shell comprises a cylinder body 7, which is provided with a gas inlet N1 for the filtered gas to enter.

[0035] The outer cylinder assembly 4 is erected in the shell through a fixing assembly, and as shown in Figure 1 , Figure 3 and Figure 4 , the outer cylinder assembly 4 comprises a vertical inverted conical shell fixing plate 23 and a first inverted conical shell 21, a plurality of second inverted conical shells 24 and a third inverted conical shell 26 arranged in sequence from bottom to top, the plurality of second inverted conical shells 24 are installed on the inverted conical shell fixing plate 23 in sequence from bottom to top, and the upper end periphery of the third inverted conical shell 26 is higher than the gas inlet N1 and abuts against the inner wall of the cylinder body 7, so that the filtered gas entering the cylinder body 7 from the gas inlet N1 rises to the third inverted conical shell 26 and is blocked by the third inverted conical shell 26 to turn back and flow downward through the filler in the plurality of second inverted conical shells 24 and the first inverted conical shell 21 in sequence, so as to be filtered; in this way, in order to ensure that the rising filtered gas is sufficiently (for example, completely) blocked by the third inverted conical shell 26 to turn back, it is necessary to have substantially no gap between the upper end periphery of the third inverted conical shell 26 and the inner wall of the cylinder body 7, and for this purpose, the outer diameter of the upper end periphery of the third inverted conical shell 26 can be made substantially consistent with the diameter of the inner wall of the cylinder body 7 so that the upper end periphery of the third inverted conical shell 26 can abut tightly against the inner wall of the cylinder body 7; alternatively, in order to completely eliminate the gap between the upper end periphery of the third inverted conical shell 26 and the inner wall of the cylinder body 7, the upper end periphery of the third inverted conical shell 26 can be welded to the inner wall of the cylinder body 7, and subsequently when the outer cylinder assembly 4 needs to be disassembled, the solder at the welding seam between the upper end periphery of the third inverted conical shell 26 and the inner wall of the cylinder body 7 can be removed using a disassembly tool (for example, a knife).

[0036] Continuing to refer to Figure 3The lower end of the lowermost second inverted conical shell 24 among the plurality of second inverted conical shells 24 is fixedly connected (e.g., welded) to the upper end of the first inverted conical shell 21. The uppermost of the uppermost inverted conical shell 24 among a plurality of second inverted conical shells 24 is fixedly connected (e.g., welded) to the lower end of the third inverted conical shell 26. It should be noted that when the upper end of the uppermost second inverted conical shell 24 is connected to the lower end of the third inverted conical shell 26, if the upper part of the inverted conical shell fixing plate 23 is too long and contacts the third inverted conical shell 26, this will prevent the lower end of the third inverted conical shell 26 from contacting the upper end of the uppermost second inverted conical shell 24, thus affecting the connection between the two. In order not to affect the connection between the upper end of the uppermost second inverted conical shell 24 and the lower end of the third inverted conical shell 26, a perforation can be made in the part of the third inverted conical shell 26 that contacts the upper part of the inverted conical shell fixing plate 23, so that the excessively long upper part of the inverted conical shell fixing plate 23 just penetrates the third inverted conical shell 26. This ensures that the lower end of the third inverted conical shell 26 contacts the upper end of the uppermost second inverted conical shell 24, and then the two are welded.

[0037] like Figure 8 As shown, the inner cylinder assembly 8 includes multiple conical shells 27 and a conical shell fixing plate 28, a connecting pipe 29, and a three-way pipe 30 connected sequentially from bottom to top. The conical shell fixing plate 28 is vertically inserted into multiple second inverted conical shells 24. The multiple conical shells 27 are stacked sequentially on the conical shell fixing plate 28 from bottom to top, forming a gas channel 34 for gas to flow from bottom to top. The gas channel 34, the connecting pipe 29, and the vertical pipe of the three-way pipe 30 are connected sequentially. The vertical pipe of the three-way pipe 30 is connected to the third inverted conical shell 26 via a first reinforcing rib 6 (e.g., fixed connection, such as welding). The upper end of the vertical pipe of the three-way pipe 30 is closed, and the horizontal pipe of the three-way pipe 30 passes through one side of the cylinder 7 and is fixed to that side of the cylinder 7. Preferably, the horizontal pipe of the three-way pipe 30 is connected to the gas outlet N2 after one side of the cylinder 7 to facilitate the smooth discharge of filtered gas to the recycling facility.

[0038] In a preferred embodiment of this disclosure, such as Figure 1As shown, the shell further comprises an upper head 13 and a lower head 1 arranged at the upper end and the lower end of the cylinder body 7 respectively. The lower end of the upper head 13 is provided with an upper flange 15, and the upper end of the cylinder body 7 is provided with a lower flange 9 matched with the upper flange 15, and the upper flange 15 and the lower flange 9 are connected in a conventional manner by fasteners, for example, including studs 10, nuts 11 and gaskets 12. The upper head 13 is provided with a manhole and filling port N3 and a gas exhaust port N6, through which the addition of filter (i.e. filter for filtering, such as activated carbon or other materials for gas filtering) is added, and through which the gas in the shell before the filter is discharged. The upper head 13 is further provided with a lifting lug 14, and the cylinder body 7 is provided with an ear support 5 at its opposite two outer sides respectively, so that the detachable gas filter device can be lifted and stably placed on the equipment frame through the ear support 5 for filtering operation.

[0039] The lower head 1 is provided with a discharge port N4 for discharging the filter and a liquid discharge port N5 for discharging the liquid. The outer cylinder assembly 4 further comprises a cylinder section 20 arranged below the first inverted cone shell 21, and the cylinder section 20 and the first inverted cone shell 21 are located in the lower head 1, and the cylinder section 20 is in communication with the discharge port N4. As shown, Figure 5 and Figure 6 As shown, the cylinder section 20 is provided with a baffle 18 and a plurality of lower blocks 17 fixedly connected (e.g. welded) to the inner wall of the cylinder section 20, and the baffle 18 is supported on the plurality of lower blocks 17 during the execution of the filter by the detachable gas filter device; the lower side of the baffle 18 is connected with a handle 16 for rotating the baffle 18, and the baffle 18 is provided with a plurality of notches 35 matched in size with the plurality of lower blocks 17 one by one, for example, the size of the notch 35 is slightly larger than the size of the corresponding lower block 17, so that under the rotation of the handle 16, the plurality of notches 35 can be aligned with the plurality of lower blocks 17 one by one when the filter needs to be discharged (as shown in Figure 6As shown in FIG. 1, the size of each notch 35 is slightly larger than the size of the corresponding lower stop 17, so that when the handle 16 is pulled downward, each notch 35 can slide over the corresponding lower stop 17, and thus the baffle 18 can be disassembled through the discharge port N4. In this way, during the filtration performed by the detachable gas filter device, the baffle 18 is supported on the plurality of lower stops 17 to block the leakage of the filler; when the filler needs to be discharged, the baffle 18 is rotated by rotating the handle 16, so that each notch 35 is located above and aligned with the corresponding lower stop 17, and then the handle 16 is pulled downward, so that each notch 35 can slide over the corresponding lower stop 17, and thus the baffle 18 can be disassembled to facilitate the discharge of the filler. When the filler is added again, the baffle 18 is sent into the cylinder segment 20 through the discharge port N4 and located above the lower stops 17, and then the baffle 18 can be supported on the lower stops 17 as long as the notches 35 are not aligned with the corresponding lower stops 17. In addition, it should be noted that because the size of the notch 35 is generally smaller than the size of the filler, when the baffle 18 is supported on the lower stops 17, the filler will not or almost not leak through the notch 35.

[0040] In a preferred embodiment of the present disclosure, the gas inlet N1, the gas outlet N2, the manhole and charging port N3, the discharge port N4, the liquid discharge port N5 and the exhaust port N6 can be opened and closed in a conventional manner in the art, and can be arranged in a conventional arrangement in the art, for example, can be arranged as shown in Table 1 below, but not limited thereto.
