Description

Chemical plant circulating water online cleaning pipeline filter

technical field

The utility model relates to a circulating water system applied to a chemical plant, in particular to an online cleaning filter for the circulating water of a chemical plant.

Background technique

In the prior art, debris and other debris in the cooling tower of the circulating water system on the chemical plant are pressurized by the circulating water pump and then enter the subsequent chemical plant, and debris such as filler often block the tube bundle of the heat exchanger in the end. , As a result, the heat transfer effect of the heat exchanger is reduced, which not only affects the production capacity of the equipment, but also greatly shortens the service life of the heat exchanger, and causes frequent shutdowns of chemical plants.

Utility model content

In view of this, the main purpose of this utility model is to provide an on-line cleaning filter for circulating water in a chemical plant. Through this technical proposal, an L-shaped filter tube is added to the short joint of the existing circulating water pipeline to pass the filtered water through The short joints of the pipeline are directly sent to the subsequent chemical equipment, and the filler fragments and other sundries are stored in the L-shaped filter tube. No matter whether the whole equipment is in working or non-working state, the miscellaneous valve can be opened to clean up the impurities, and the circulating water is realized. Online cleaning, while avoiding the disassembly and assembly process of ordinary filters, reduces the labor intensity of maintenance personnel, and creates conditions for the long-term stable operation of chemical equipment.

In order to achieve the above object, the technical solution of the utility model is realized as follows: an online cleaning pipeline filter for circulating water in a chemical plant, including a pipeline nipple, the water inlet of the pipeline nipple is connected to the circulating water pump, and the pipeline nipple The outlet pipe of the pipe is connected with the subsequent chemical equipment, and it is characterized in that it includes an L-shaped filter pipe, an annular disk and a miscellaneous discharge valve. The inner wall of the inlet pipe of the pipe nipple is welded together, and the straight pipe end of the L-shaped filter pipe is the water inlet of the filter pipe, which is connected to the inner surface of the ring plate fixed in the pipe nipple through the connecting flange and bolts. Connection, the elbow end of the L-shaped filter tube passes through the side wall of the pipe nipple to form a filter pipe miscellaneous outlet, the miscellaneous valve is connected to the elbow end of the L-shaped filter pipe, and the L-shaped filter pipe located in the pipe nipple Several strip-shaped through-holes are arranged on the side wall.

It includes a wire mesh, and the wire mesh is arranged on the inner side of the strip-shaped through hole on the side wall of the L-shaped filter tube.

A pressure gauge communicating with the inside of the L-shaped filter tube is arranged on the elbow end of the L-shaped filter tube.

The beneficial effect of adopting the above technical solution is: an online cleaning filter for circulating water in a chemical plant. Through this technical solution, the online cleaning function of the filter can be easily realized, and the filter can be cleaned without shutting down the circulating water pump and pipeline. The filler fragments and other sundries filtered out of the medium are discharged from the circulating water system, effectively preventing the sundries from entering the subsequent circulating water system, causing problems such as blockage of the tube bundles of heat exchangers and other equipment, and ensuring long-term stable operation of chemical plants.

detailed description

The specific embodiments of the present utility model will be described in further detail below in conjunction with the accompanying drawings.

As shown in Fig. 1 and Fig. 2, the circulating water online cleaning pipeline filter of the chemical plant involved in the utility model includes a pipeline nipple 1, the water inlet of the pipeline nipple 1 is connected with the circulating water pump 2, and the pipeline nipple 1 The outlet pipe of the pipe is connected with the subsequent chemical equipment 3, and also includes an L-shaped filter pipe 4, an annular disc 5 and a miscellaneous discharge valve 6, the annular disc 5 is arranged in the water inlet of the pipe nipple 1, and the annular disc 5 The outer edge of the pipe nipple 1 is welded together with the inner wall of the water inlet pipe. The straight end of the L-shaped filter pipe 4 is the water inlet of the filter pipe. The inner surface of the annular disk 5 in the section 1 is connected, and the elbow end of the L-shaped filter pipe 4 passes through the side wall of the pipe nipple 1 to form a filter pipe miscellaneous outlet. The pipe ends are connected, and several strip-shaped through-holes 8 are arranged on the side wall of the L-shaped filter pipe 4 located in the pipeline nipple 1 .
