Anti-clogging system of the naphtha cracking process, thermal cracking gas sampler

摘要

The invention consists of a high-pressure steam cleaning device and the condensed liquid discharge apparatus to prevent clogging, a sampling device inlet portion on the anti-clogging system of the pyrolysis gas sampling device from naphtha cracking process. High pressure steam cleaning device is composed of high-pressure steam so as to come to the side of the device injecting the high-pressure water vapor in the opposite direction in which the sample is collected in a sampling device. Nozzles in the side of the device has a gate valves for controlling the input and output of the filter and the high-pressure steam to remove impurities that might be included in the high-pressure water vapor is provided, the body of the device, the high-pressure water vapor is connected to the lower end of the body the interior is in a blank space to be jetted through. The bottom of said body has a nozzle for spraying a high-pressure steam for the foreign matter blocks the sampling device is installed, the tip of the nozzle is attached is smaller than the nozzle tip diameter to accelerate the ejection speed of the high-pressure steam. There are also, the condensed liquid water pipe center of the body portion, and this in order to vaporize by the liquid to hot main process line condensate came down to ride the wall surface of the apparatus in a sampling device and eliminate the incomplete sample collection method which is again condensed and vaporized again, small is to assemble a liquid condensate drain the condensed liquid of the drop is set up to return to the main process line without significantly to be vaporized again, the droplet. The system of the present invention due to clogging is removed, the clogging of pyrolysis gas sampling device of the naphtha cracking process to reduce the time delay for the sample supply to the analyzer provides a substantial data on the process adjustment in real time, and a sampling device to prevent the waste of human resources, and that will reduce the risk of accidents due to leakage of hot gas during maintenance.
