Description

A flushing system for a sulfur absorption tower membrane box type liquid level transmitter

technical field

The utility model relates to a flushing system for a membrane box type liquid level transmitter of a sulfur absorption tower.

Background technique

The liquid level gauge of the desulfurization absorption tower is used for more accurate measurement. The top liquid level gauge is directly connected to the measuring pipe at the top of the desulfurization absorption tower using a capsule type liquid level transmitter. However, it is often prone to slurry precipitation in the absorption tower, which leads to inaccurate measurement of the liquid level transmitter, and it is time-consuming and labor-intensive to clean the measurement pipeline every time the unit is shut down.

Utility model content

In order to solve the above technical problems, the utility model provides a flushing system for a membrane box type liquid level transmitter of a sulfur absorption tower.

The utility model is realized through the following technical solutions.

The utility model provides a flushing system for a sulfur absorption tower membrane box type liquid level transmitter, including a flushing main pipe, an absorption tower, a flushing pipeline A, a flushing pipeline B, a liquid level transmitter, a membrane box, a flushing water ring, Measuring pipeline; the liquid level transmitter is installed on the bellows, the bellows is connected to the valve through the flushing water ring, the valve is connected to the absorption tower through the measuring pipeline, and the flushing main pipe is respectively passed through the flushing pipeline A and The flushing pipe B is connected to the flushing water ring and the measuring pipe.

Branch valves are installed on the flushing pipeline A and the flushing pipeline B.

The flushing pipeline A is connected to the middle part of the branch valve.

The beneficial effects of the utility model are: a flushing water ring and a primary valve for isolation are added between the pressure transmitter and the measuring pipeline, two-way high-pressure flushing water is used for flushing and blockage removal, and one path of flushing water is used to flush the liquid level transmitter Diaphragm box, all the way to flush the valve with flushing water before measuring the pipe. It can not only efficiently solve the inaccurate measurement of the liquid level transmitter caused by slurry precipitation, but also effectively protect the bellows of the bellows pressure transmitter.

detailed description

The technical solution of the utility model is further described below, but the scope of protection is not limited to the description.

A sulfur absorption tower membrane box type liquid level transmitter flushing system, including flushing main pipe 1, absorption tower 2, flushing pipeline A3, flushing pipeline B4, liquid level transmitter 5, membrane box 6, flushing water ring 7, Measuring pipeline 10; said liquid level transmitter 5 is installed on bellows 6, said bellows 6 is connected with valve 8 through flushing water ring 7, and said valve 8 is connected with absorption tower 2 through measuring pipeline 10, said The main flushing pipe 1 is connected to the flushing water ring 7 and the measuring pipe 10 through the flushing pipe A3 and the flushing pipe B4 respectively.

Branching valves 9 are installed on the flushing pipeline A3 and the flushing pipeline B4.

The flushing pipeline A3 is connected to the middle of the branch valve 9 .

When flushing, the present invention first closes the front valve 10 of the flushing water ring, opens the branch valve 9 on the flushing pipeline A3 and first flushes the measuring pipeline, and then closes the branching valve 9 on the flushing pipeline A3 after the flushing of the measuring pipeline is completed. Open the front valve 10 of the flushing water ring, open the branch valve 9 on the flushing pipeline B4, and flush the capsule. In this way, the problem of damage to the bellows caused by the excessive pressure of the bellows caused by direct flushing of the bellows of the pressure transmitter due to the blockage of the measuring pipeline is avoided.
