Automatic dredging and draining device for autonomous power pipeline

Abstract

The invention discloses an automatic dredging and draining device for an autonomous power pipeline, which is used for the dredging and draining of a flue gas transmission pipeline. The device comprises a drainage pipe, a rotating shaft, a plurality of scraping plates, a wind cup, and spiral blades, wherein the upper end of the drainage pipe is fixedly connected with the lower end surface of the flue gas transmission pipeline and is communicated with the interior of the flue gas transmission pipeline, the drainage pipe is used for draining accumulated water and dirt in the flue gas transmissionpipeline, and the end part, connected with the flue gas transmission pipeline, of the drainage pipe is of a flaring structure; the rotating shaft is coaxially arranged with the drainage pipe and oneend of the rotating shaft penetrates into the drainage pipe, and the other end of the rotating shaft extends upwards into the flue gas transmission pipeline; the scraping plates are of a sheet-shapedstructure and are fixed in an annular array at the peripheral side position of the rotating shaft at the top of the drainage pipe, and the scraping plates are rotationally constrained in the flaring structure at the top of the drainage pipe; the wind cup is connected with the end, located in the flue gas transmission pipeline, of the rotating shaft, and drives the rotating shaft to rotate driven by the flue gas; and the spiral blades are arranged at the part of the rotating shaft penetrating into the drainage pipe. According to the invention, the technical solution is reliable in implementation, high in dredging and draining efficiency, and is capable of saving energy.

Description

technical field [0001] The invention relates to the field of auxiliary cleaning devices for flue gas pipelines, in particular to an automatic dredging and drainage device for autonomous power pipelines. Background technique [0002] Existing industrial pipelines, such as flue gas desulfurization equipment, the flue gas at the outlet of the induced draft fan or the flue near the chimney contain a lot of water. In the horizontal flue, the water will condense and accumulate at the bottom. Drainage pipes are prone to congestion and often need to rely on artificial drainage. The water discharge is not smooth, resulting in a large amount of water accumulation in the horizontal flue, which will further cause problems such as corrosion at the bottom of the horizontal flue. There are still the following technical problems that need to be solved: [0003] ①.

AI Technical Summary

Problems solved by technology

[0002] Existing industrial pipelines, such as flue gas desulfurization equipment, the flue gas at the outlet of the induced draft fan or the flue near the chimney contain a lot of water. In the horizontal flue, the water will condense and accumulate at the bottom. Drainage pipes are prone to congestion and often need to rely on artificial drainage. The water discharge is not smooth, resulting in a large amount of water accumulation in the horizontal flue, which will further cause problems such as corrosion at the bottom of the horizontal flue. There are still the following technical problems that need to be solved:

[0003] ①. Water accumulation problem: Since the bottom of the existing flue is a flat structure, the water body cannot be concentrated in one place, so it is possible to divert the water to one place for further processing

[0004] ②, blockage problem: because the flue gas contains a lot of impurities, which combine with the condensed water, it is easy to block the drain outlet after precipitation, so try to clean up the sediment in time

[0005] ③. Power problem: The working environment in the flue is complex, and conventional electric drive equipment such as motors are difficult to implement under the influence of temperature, humidity, and corrosion. The power problem needs to be solved

The sink cannot collect condensed water well, and it will still cause serious corrosion at the bottom of the flue

[0009] ② There is a lot of dust in the flue, which can easily cause the nozzle of the downpipe to be blocked

A clogged downspout will cause condensate to drain
