Description

Technical Field

[0001] The utility model relates to the technical field of dust hoppers of dust collectors, and particularly relates to a device for preventing dust accumulation in a dust hopper of a dust collector. Background Art

[0002] Dust collectors, as essential key equipment in the environmental governance system, their performance and efficiency are directly related to the improvement of air quality and the effectiveness of environmental protection. Among various dust removal technologies, dry dust collectors occupy an important position with their high efficiency and stability, and are widely used in many industrial fields such as electric power, steel, and cement. Such dust collectors, such as electrostatic precipitators and bag filters, capture and collect particulate matter in the air into the dust hopper through specific physical mechanisms, and then use a pneumatic conveying system or a professional suction and discharge vehicle to safely and orderly transfer the dust out of the treatment area. However, a significant challenge faced by dry dust collectors during actual operation is the problem of dust accumulation and caking on the inner wall of the dust hopper. The design of the dust hopper, especially its inverted triangular cone structure with a rectangular cross-section, is intended to optimize the collection and discharge efficiency of dust. The taper change of the conical hopper does help to guide the dust to smoothly slide to the outlet. However, when the treated dust contains high-temperature components, combustion agent residues, or has high viscosity, the situation becomes complicated. After these special dusts stay in the dust hopper for a long time, they will gradually undergo physical and chemical reactions with the inner wall surface, forming sticky lumps that are difficult to peel off. This caking phenomenon will not only gradually thicken but also continuously attract subsequent deposited dust like a "snowball", forming a vicious cycle. Once the caking reaches a certain scale, it will seriously hinder the normal ash discharge process of the dust hopper and even cause blockage of the entire dust removal system. For electrostatic precipitators, due to their unique dust removal mechanism, once caking occurs on the inner wall of the dust hopper, it is particularly difficult to handle. Traditional cleaning methods such as pneumatic conveying or suction and discharge vehicles often fail to work, and manual intervention is required for time-consuming and laborious cleaning operations. This not only increases the equipment downtime for maintenance, reduces production efficiency, but also consumes a large amount of human resources and material costs, imposing a significant burden on the operation of the enterprise.

[0003] According to the Chinese patent with the patent number CN 221334729 U, a dust collector hopper is disclosed, which is arranged below the dust collector. The flue gas in the dust collector flows along the first horizontal direction. The dust collector hopper includes a lower ash hopper group and an upper ash hopper. The lower ash hopper group includes a plurality of connected lower ash hoppers, and the plurality of lower ash hoppers are arranged along the first horizontal direction. The upper ash hopper is connected above the lower ash hopper group, surrounds the lower ash hopper group, and encloses a flow space communicating with the plurality of lower ash hoppers above the lower ash hopper group, so that the ash flowing out of the ash outlet of the dust collector flows into the plurality of lower ash hoppers through the flow space. Since the ash removal amount in the front stage of the dust collector is greater than that in the rear stage, the lower ash hoppers closer to the front in the first horizontal direction accumulate more ash, and the lower ash hoppers closer to the rear accumulate less ash. When the front-stage lower ash hopper is full of ash, the ash overflows from the ash inlet above the lower ash hopper, and the overflowing ash will flow towards the rear-stage lower ash hopper in the flow space, realizing uniform distribution of the load in the lower ash hopper.

[0004] However, during the use of the existing dust collector hopper, due to the increased viscosity of the fly ash particles, they are prone to adhere to other fly ash particles, resulting in the deposition of fly ash on the inner wall of the dust collector hopper. Moreover, the shape of the hopper is conical and the installation height is relatively high, causing difficulties for users to clean the hopper. Summary of the Utility Model

[0005] The technical problem to be solved by the present utility model is to overcome the problems existing in the use of the existing dust collector hopper.
