Pipeline cleaning device for chemical heat exchanger

Abstract

The invention belongs to the field of chemical engineering, and particularly relates to a pipeline washing device for a chemical heat exchanger. The pipeline washing device comprises a supporting plate, a lifting module, a connecting and disconnecting module, a washing module and a water tank; the lifting module is fixed to the supporting plate, and the lifting module is used for supporting the washing module and driving the washing module to move up and down to wash the inner wall of a pipeline; the washing module is mounted at the lower right end of the lifting module, and the washing module is used for washing the inner wall of the pipeline; the connecting and disconnecting module is mounted on the washing module and used for controlling flow-in and flow-out of waterflow in the washing module; and the water tank is used for supplying water needed by the pipeline washing device. The pipeline washing device repeatedly washes the inner wall and the upper end of the pipeline through joint action of the lifting module, the connecting and disconnecting module and the washing module, and the washing effect is good.

Description

technical field [0001] The invention belongs to the field of chemical industry, in particular to a pipeline cleaning device for chemical heat exchangers. Background technique [0002] In chemical production, there are some heat exchangers with small diameter pipes, and this type of heat exchanger is composed of multiple small diameter pipes, but the cleaning of such heat exchanger pipes is extremely inconvenient. During the use of this kind of heat exchanger, some impurities, crystals and dirt will adhere to the inner wall of the heat exchanger pipe, which will gradually reduce the diameter of the pipe. If it is not cleaned in time and effectively, when the scaling reaches a certain level, It will seriously affect the normal use of the pipeline. At present, high-pressure water washing is mainly used to clean dirt. When high-pressure water washing is used, the descaling effect is often difficult to control, so the expected purpose cannot be achieved. [0003] In view of thi...

[0002] In chemical production, there are some heat exchangers with small diameter pipes, and this type of heat exchanger is composed of multiple small diameter pipes, but the cleaning of such heat exchanger pipes is extremely inconvenient

During the use of this kind of heat exchanger, some impurities, crystals and dirt will adhere to the inner wall of the heat exchanger pipe, which will gradually reduce the diameter of the pipe. If it is not cleaned in time and effectively, when the scaling reaches a certain level, Will seriously affect the normal use of the pipeline

At present, high-pressure water washing is mainly used to clean dirt. When high-pressure water washing is used, the descaling effect is often difficult to control, so the expected purpose cannot be achieved.
