Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust removal chambers, in particular to a dust removal chamber for economizers. Background Art
[0002] Economizer is a device installed at the lower part of the flue at the rear of the boiler to recover the waste heat of the exhaust gas. The traditional economizer is a cast iron fin type with a stacked assembly. The economizer is prone to ash accumulation and blockage. The efficiency of the economizer is greatly reduced and the resistance is greatly increased after ash blockage. A dust removal chamber is usually used to remove dust from the economizer.
[0003] As the economizer is used for a longer time, too much dust accumulates on both sides of the economizer, affecting the heat exchange efficiency of the economizer. The existing dust removal chamber is usually used to remove dust inside the economizer, but cannot remove dust on both sides of the economizer, resulting in poor dust removal effect. Utility Model Content
[0004] The purpose of the utility model is to provide a dust removal chamber for an economizer to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dust removal chamber for an economizer, comprising a dust removal chamber body, fixed plates are symmetrically arranged on both sides of the dust removal chamber body, an electric telescopic rod is arranged at the top of the fixed plate, the tops of the two electric telescopic rods located on the same side are commonly connected to a support plate, an ash suction main pipe is arranged at the top of the support plate, a plurality of ash suction branch pipes are arranged on one side of the ash suction main pipe, a suction fan is arranged on one side of the dust removal chamber body, a connecting pipe is fixedly connected to one side of the suction fan, and the other end of the connecting pipe is connected to the ash suction main pipe.
[0006] The following improvement is made in the solution of the present application: dust suction holes are symmetrically opened on one side of the dust removal chamber body, and the suction fan is fixedly installed on the outer side of the dust suction hole.
[0007] The following improvement is made in the solution of the present application: a plurality of fixing rings are provided at the top of the support plate, and the interiors of the plurality of fixing rings are connected to the ash suction main pipes.
[0008] The following improvement is made in the solution of the present application: a dust discharge block is provided on one side of the dust removal chamber body, and a dust discharge port is provided inside the dust discharge block.
[0009] The following improvement is made in the solution of the present application: a partition is provided inside the dust removal chamber body, the height of the partition is lower than the internal height of the dust removal chamber body, and reinforcing ribs are fixedly provided on both sides of the partition.
[0010] The following improvement is made in the solution of the present application: a dust outlet is provided at the top of the dust removal chamber body.
[0011] Compared with the prior art, the utility model provides a dust removal chamber for an economizer, which has the following beneficial effects:
[0012] The dust removal chamber for the economizer is provided with an electric telescopic rod, a support plate, an ash suction main pipe, an ash suction branch pipe, a suction fan, a connecting pipe and an ash suction hole. When too much dust is accumulated on both sides of the economizer, the suction fan is started to provide wind force, and the electric telescopic rod is started at the same time. The electric telescopic rod drives the support plate to move upward, and the support plate drives the ash suction main pipe to move upward, so that the ash suction branch pipe absorbs the dust on both sides of the economizer. The dust enters the ash suction main pipe through the ash suction branch pipe, and then enters the interior of the dust removal chamber body through the connecting pipe and the ash suction hole. The dust on both sides of the economizer can be cleaned, thereby improving the ash removal efficiency of the dust removal chamber body and thus improving the heat exchange efficiency of the economizer.
