Description

Technical Field

[0001] This utility model relates to the field of coal chutes in power plants, specifically a high-drop coal chute buffer and dust suppression structure. Background Technology

[0002] In traditional coal conveying systems of coal-fired power plants, the large drop in coal flow causes traditional coal chutes to increase coal flow and impact force, generating large amounts of dust and potentially damaging downstream equipment. The chaotic coal flow mixes thoroughly with air within the chutes, creating a high-pressure, dust-laden airflow that causes dust spraying at the feed chute outlet, resulting in a poor working environment and posing health risks to power plant personnel. The traditional solution is to use dust collectors, installing suction points at the head hood and feed chute to address the dust problem; however, this method increases the construction cost of the coal conveying system. Summary of the Invention

[0003] To address the aforementioned technical problems, this utility model provides a high-drop coal chutes buffer and dust suppression structure, which can slow down the coal flow velocity, suppress dust in the coal chutes, and reduce construction costs.

[0004] The technical solution is as follows: a high-drop coal chutes buffer dust suppression structure, which includes a coal chutes, characterized in that guide plates arranged vertically and vertically are installed on the inner walls of the left and right sides of the coal chutes, the guide plates are arranged inclined downwards, and a buffer airlock is installed at the bottom outlet of the coal chutes.

[0005] A further feature is that the angle between the guide plate and the horizontal plane is not less than 60°; The inner wall of the coal chute is provided with ribs to support the guide plate.

[0006] With this invention, a buffer guide plate is installed inside the coal chute to reduce the coal flow velocity and control the coal flow trajectory. A buffer airlock is connected to the outlet of the coal chute to reduce dust and the impact of coal falling on downstream equipment, and to suppress dust in the coal chute. The structure is simple and the construction cost is reduced. Attached Figure Description

[0007] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0008] See Figure 1 As shown, a high-drop coal chutes buffer dust suppression structure includes a coal chutes 3. The inner walls of the left and right sides of the coal chutes 3 are equipped with staggered guide plates 1. The guide plates 1 are inclined downwards and the angle between the guide plates 1 and the horizontal plane is not less than 60° to ensure that the coal dust can fall smoothly. In order to improve the strength of the guide plates 1, the inner wall of the coal chutes 3 is provided with supporting ribs 2. A buffer airlock 4 is installed at the bottom outlet of the coal chutes 3.

[0009] As the coal falls and passes through the staggered guide plates 1, the coal flow velocity decreases and the coal flow trajectory is altered, which can suppress dust generation and buffer the falling coal. Then it enters the buffer airlock 4, where the airlock baffles will slow down the coal flow again. When the coal accumulates on the airlock baffles to a certain extent, the airlock baffles open, and the coal flow passes through into the downstream equipment, while reducing the impact on the downstream equipment.
