Abstract
Description
Technical Field
[0001] This utility model relates to a water discharge device for an external sampling pipe of a coke oven gas pipeline, belonging to the technical field of gas water seal equipment in the metallurgical industry. Background Technology
[0002] During the coke oven gas purification process, it is necessary to sample and test the gas periodically. The common method is to extend a sampling pipe from above the gas pipeline to a lower location or operating platform for convenient sampling. A sampling valve is installed at the bottom of the sampling pipe. When sampling is required, the sampling valve is first opened to release the condensate in the sampling pipe, and then the sampling hose is connected for sampling. When the amount of condensate in the sampling pipe is large, the venting time is long, and gas may spray out with the condensate, affecting the operating environment and posing a safety hazard. Utility Model Content
[0003] The purpose of this invention is to provide a water discharge device for an external sampling pipe of a coke oven gas pipeline, which can automatically and in real time discharge condensate from the gas sampling pipe, avoiding manual drainage operations, eliminating safety hazards, and solving the problems existing in the background technology.
[0004] The technical solution of this utility model is:
[0005] A water discharge device for an external sampling pipe of a coke oven gas pipeline includes a steam evacuation pipe, a water seal cylinder, a water seal pipe, a steam inlet pipe, a base, a heat insulation cylinder, a water supply pipe, a water discharge valve, a water discharge pipe, a drain pipe, a sampling pipe, a sampling pipe drain valve, and a gas pipeline. The heat insulation cylinder is fixed on the base, and the water seal cylinder is fixed in a ring around the heat insulation cylinder. The steam evacuation pipe and the steam inlet pipe are respectively connected to the heat insulation cylinder. The water seal pipe, the water supply pipe, and the drain pipe are respectively connected to the water seal cylinder. One end of the water discharge pipe is connected to the water seal cylinder, and the other end of the water discharge pipe is connected to the sampling pipe drain valve through the water discharge valve. The sampling pipe drain valve is connected to the sampling pipe, and the sampling pipe is connected to the gas pipeline.
[0006] The steam inlet pipe is connected to the top of the insulation cylinder, and the steam outlet pipe is connected to the bottom of the insulation cylinder.
[0007] A water supply valve is installed on the water supply pipe.
[0008] Both the drain pipe and the water seal pipe are inserted into the water seal cylinder and are a certain distance from the bottom of the water seal cylinder.
[0009] The water seal cylinder is provided with a vent at the bottom.
[0010] Both the water seal cylinder and the insulation cylinder have an insulation layer on their outer walls.
[0011] A sampling valve is installed on the sampling tube.
[0012] The beneficial effects of this invention are as follows: During operation, the condensate in the gas sampling tube is directly discharged through the drain pipe and water seal pipe inside the water seal cylinder, achieving a water seal effect. The real-time discharge of condensate from the sampling tube reduces the need to drain condensate before sampling, eliminates the safety and environmental hazards of gas leaking out with the condensate, and shortens the sampling time. The structure is simple, easy to manufacture, and convenient to install and maintain. Attached Figure Description
