Description

Technical Field

[0001] This utility model relates to the field of waste incinerator technology, specifically to a dioxin interception device combining activated carbon powder and hollow fiber membrane filter element. Background Technology

[0002] Currently, using the best coated filter bags, the highest dust removal precision can reach 1-6 mg / m³. 3 This figure is quite ideal for pure dust filtration, but insufficient for the 0.1 ng / L dioxin emission standard. Only by treating the dust emitted from waste incineration flue gas to the microgram level can the existing dioxin emission requirements be consistently met or exceeded. Therefore, the dioxin interception structure of existing waste incineration systems should be improved.

[0003] Chinese patent CN211216077U discloses a dioxin interceptor combining activated carbon powder spraying and a hollow fiber membrane filter. Replacing the existing baghouse dust collector + activated carbon powder spraying structure with a hollow fiber membrane dust purification device can increase dust filtration efficiency by more than 1000 times, thereby increasing dioxin interception efficiency by more than 10 times, significantly improving the cleanliness of waste incineration.

[0004] The shortcomings of the existing solutions are as follows: Hollow fiber membrane filter elements must be cleaned regularly and periodically during continuous normal operation. The cleaning of hollow fiber membrane filter elements is relatively complicated, consisting of multiple steps such as forward washing, reverse washing, air wiping, air-water washing, and chemical cleaning. The filter element needs to be removed during cleaning, and the installation structure of hollow fiber membrane filter elements in the existing technology is not convenient for disassembly and maintenance. Utility Model Content

[0005] The purpose of this invention is to provide a dioxin interception device that combines activated carbon powder spraying with a hollow fiber membrane filter element, so as to solve the technical problem that the installation structure of the hollow fiber membrane filter element in the prior art is not convenient for disassembly and maintenance.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A dioxin interception device combining activated carbon powder spraying and hollow fiber membrane filter element, comprising:

[0008] The combustion furnace has an ash outlet at the bottom, a mixer at one end, and an air outlet at the other end. The mixer is equipped with an activated carbon nozzle and an air inlet pipe.

[0009] The filter element holder includes a mechanism mounting plate. An adjusting plate is slidably mounted on one side of the mechanism mounting plate, and a fixing plate is fixedly connected to the other side of the mechanism mounting plate. The adjusting plate is slidably mounted along the length of the mechanism mounting plate. A sleeve is fixedly connected to the end faces of the adjusting plate and the fixing plate that are close to each other. A sleeve cavity is opened on the end faces of the sleeves on both sides that are close to each other. A telescopic rod is provided between the sleeves on both sides. The filter element holder is set in the combustion furnace, and a hollow fiber membrane filter element is set on the filter element holder.

[0010] As a further embodiment of this utility model: the two ends of the hollow fiber membrane filter element are respectively fitted into the fitting cavities of the fittings on both sides, and an installation groove is opened on the side end face of the fitting. The air inlet pipe and air outlet pipe of the hollow fiber membrane filter element are respectively fitted into the installation grooves of the fittings on both sides.

[0011] As a further embodiment of this utility model: connecting protrusions are symmetrically distributed and fixedly connected on the side end face of the socket, and the two ends of the telescopic rod are respectively connected to the connecting protrusions of the two side sockets.

[0012] As a further embodiment of this utility model: an adjustment slot is provided on the mechanism mounting plate, and an adjustment block is fixedly connected to the adjustment plate. The adjustment block is located at the opening of the adjustment slot on the mechanism mounting plate. A pad is provided on the end face of the mechanism mounting plate. The pad and the adjustment block are respectively located on both sides of the adjustment slot. Threaded holes are provided through the pad and the adjustment block.

[0013] As a further embodiment of this utility model: both the pad and the adjusting block are threaded with screws, the screws passing through the pad and the adjusting groove and connecting to the adjusting block.

[0014] As a further embodiment of this utility model: an installation plate is fixedly connected to the inner wall of the combustion furnace, an installation bracket is fixedly connected to the installation plate, a mechanism fixing bracket is fixedly connected to the mechanism installation plate, and the mechanism fixing bracket is fixedly connected to the installation bracket.

[0015] The beneficial effects of this utility model are:

[0016] When maintenance of the hollow fiber membrane filter element is required, the screws on the pad and adjusting block can be removed, allowing the adjusting plate to slide relative to the fixed plate. This enables the hollow fiber membrane filter element between the two side sleeves to be removed for cleaning, maintenance, or replacement, facilitating disassembly and maintenance. The two ends of the hollow fiber membrane filter element are respectively fitted into the sleeve cavities of the two side sleeves. During the purification process, the two ends of the hollow fiber membrane filter element are frequently subjected to impacts from high-pressure gas and high-pressure water flow. The sleeves secure the hollow fiber membrane filter element, increasing the overall impact resistance of the structure and improving the reliability of the device. A telescopic rod is provided between the two side sleeves. This telescopic rod reduces the shaking amplitude of the hollow fiber membrane filter element during impacts from high-pressure gas and high-pressure water flow, further enhancing the reliability of the device.
