Cleaning system and cleaning method for preventing scabbing and blocking at dry-wet junction of pipeline

Abstract

The invention relates to the field of sodium carbonate production, in particular to a cleaning system and method for preventing scabbing and blocking at the dry-wet junction of a pipeline. The cleaning system comprises a central cylinder, an elbow, a transverse pipe, a washing tower and a cleaning mechanism. And the cleaning mechanism comprises a moving seat and a rotating drum. The moving seat is slidably matched with the transverse pipes, and the transverse pipes are slidably sealed. The rotating cylinder is arranged perpendicular to the axial direction of the transverse pipe and rotatably installed in an inner cavity of the moving base, and a receding opening for the rotating cylinder to be exposed out is formed in the surface of the moving base. And an inner cavity of the rotary drum is communicated with a cleaning liquid supply pipe. And spray holes are formed in the outer side wall of the rotary drum. And the rotary drum is driven by a second driver. The device can effectively prevent alkali dust from forming alkali scars at the'dry and wet junction 'of the inner wall of the three-way pipeline, reduces the blowing-out cleaning frequency, and has positive significance in reducing the production cost, improving the production efficiency and guaranteeing the production continuity.

Description

technical field [0001] The invention relates to the field of soda ash production, in particular to a cleaning system and a cleaning method for preventing scabbing and clogging at the dry-wet junction of pipelines. Background technique [0002] The calciner is one of the important equipments in the soda ash preparation industry. The furnace gas generated by its calcination needs to be transported to the washing tower through the three-way pipeline (elbow, central tube and horizontal tube) for washing and then discharged. [0003] At present, the commonly used elbows are mostly used to connect the central tube and the horizontal pipe at 90 degrees or 45 degrees. Since the furnace gas mainly contains water vapor and alkali dust, the furnace gas is easily formed inside the three-way pipeline when it is transported through the three-way pipeline. Alkali scars need to be cleaned regularly, otherwise it will cause blockage of the three-way pipeline and affect the overall balance of...

Problems solved by technology

[0003] At present, the commonly used elbows are mostly used to connect the central tube and the horizontal pipe at 90 degrees or 45 degrees. Since the furnace gas mainly contains water vapor and alkali dust, the furnace gas is easily formed inside the three-way pipeline when it is transported through the three-way pipeline. Alkali scars need to be regularly shut down for cleaning, otherwise the three-way pipeline will be blocked and affect the overall balance of the calciner operating system

[0004] In order to solve the above problems, spraying devices are usually installed at the elbows, but the spraying cannot effectively block the rise of water vapor, so it still cannot solve the problem of alkali scars on the three-way pipeline, but instead concentrates the alkali scars on the three-way pipeline The "junction between wet and dry"
