Problems solved by technology

[0002] At present, in the electrolytic brine process of the chlor-alkali chemical industry, after the brine is heated by the heat exchange equipment, it needs to enter the electrolytic cell for electrolysis; the static electricity generated during electrolysis will return from the electrolytic cell to the heat exchange equipment due to the conductivity of the brine, and then affect the heat exchange. The equipment causes electrostatic corrosion, which greatly reduces the service life of the heat exchange equipment, and the heat exchange equipment needs to be replaced every six months on average

Abstract

The invention relates to an electrostatic closure device, comprising a tube with opening on both ends; wherein, the two ends of the tube are conical, and the middle is round; the inner diameter of the middle part is bigger than the two conical openings. A metal closure plate vertical with axis of the tube is seal-arranged in the tube, which is earthed and provided with a plurality of screen holes. The sum of cross-sectional area of the screen holes is bigger or equal to the cross-sectional area of the conical opening. A closure device is arranged between the heat exchanging equipment and the electrolytic bath, which can stop the electrostatic coming back from the electrolytic bath to conduct into the ground, and protect the heat exchanging equipment. The closure plate using red copper or silver as material is more stability and uneasy to be corroded. The closure rate of the electrostatic can reach 100 percent, and the service life of the heat exchanging equipment improves by three times. The sum of cross-sectional area of the screen holes on each closure plate is bigger or equal to the cross-sectional area of the conical opening, which avoids decreasing working efficiency while water flow in the pipeline reducing.

Description

technical field [0001] The invention relates to a device capable of intercepting static electricity, in particular to an electrostatic interceptor used in the chemical industry. Background technique [0002] At present, in the electrolytic brine process of the chlor-alkali chemical industry, after the brine is heated by the heat exchange equipment, it needs to enter the electrolytic cell for electrolysis; the static electricity generated during electrolysis will return from the electrolytic cell to the heat exchange equipment due to the conductivity of the brine, and then affect the heat exchange. The equipment causes electrostatic corrosion, which greatly reduces the service life of the heat exchange equipment, and the heat exchange equipment needs to be replaced every six months or so on average. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electrostatic current interceptor that can protect heat exchange ...
