Description

Technical Field

[0001] The utility model relates to the technical field of electric capture tar sampling brackets, in particular to a coal gas electric capture tar-containing on-site sampling bracket device. Background Art

[0002] With increasing environmental awareness, this technology has been widely used in various industries, such as steel, coking, and gas. Using electrostatic precipitator (ECP) tar sampling, it is possible to accurately detect harmful substances in coal gas, providing an important basis for subsequent environmental protection management. At the Baosteel Group Steel Union Coal and Coke Chemical Branch, raw gas delivered from the coke oven is separated in a gas-liquid separator. After cooling in a horizontal tube primary cooler, the raw gas is removed from impurities such as tar and naphthalene in an EPC. The research laboratory is responsible for detecting tar content in EPC coal gas. Connect the sampling hose with a dry and weighed glass sintered filter, make the sintered filter and the sampling hose in a horizontal line, and insert the sampling hose parallel to the middle of the gas pipe. To prevent dust and tar from dripping into the filter, the opening of the sintered filter should be in the direction of the gas flow. After 5 to 10 minutes, quickly turn the filter 180 degrees so that the opening is facing the direction of the gas flow, and adjust the flow rate to 1 to 3 L / min. According to the tar content in the gas, generally allow 200 L of gas to pass through the filter. After sampling, remove the filter from the gas pipe and wipe off the tar and other dirt on the outer surface of the pipe. However, during the sampling process at the gas port, it was found that the connection between the sintering device and the sampling hose must be in a horizontal line. The on-site conditions for sampling were insufficient, and the workers had to hold it by hand, which could not ensure that it remained horizontal during the process. At the same time, the negative pressure pump at the other end of the sintering device also needed to be manually pressed to connect. The entire process made it even more difficult to ensure that the two connection points were in a horizontal line, which led to the phenomenon of "no control" and sampling failure during the sampling process. It was also easy to cause safety problems. For this reason, we proposed a gas electrostatic capture tar-containing on-site sampling bracket device to solve the above problems. Utility Model Content

At the same time, the negative pressure pump at the other end of the sintering device also needs to be manually pressed to connect.
