Multi-chamber water seal tank for coal gas pipeline

Abstract

The invention relates to a multi-chamber water seal tank for a coal gas pipeline. The multi-chamber water seal tank comprises a water seal tank body; an inner space of the water seal tank body is partitioned by partition plates into a plurality of independent chambers including an inlet chamber, an outlet chamber and at least one middle chamber; the top of the inlet chamber is provided with an industrial water inlet and a coal gas condensate inlet, and the top of the outlet chamber is provided with a diffusion port; the upper portion of each partition plate and one side of the upper portion ofthe outlet chamber are provided with overflow ports respectively; bottoms of the inlet chamber, each middle chamber and the outlet chamber are provided with emptying ports respectively; the inlet chamber, each middle chamber and the outlet chamber are provided with high-position liquid level meter connection ports and low-position liquid level meter connection ports. The multi-chamber water sealtank is applicable to high-pressure coal gas pipelines; by a multilevel chamber series connection structure, technical problems of complex design, cost increasing and inconvenience in operation due tooverhigh liquid seal pressure of a conventional cylindrical vertical coal gas water seal tank are solved, and simple design, convenience in operation and great utilization effects are realized.

Description

technical field [0001] The invention relates to the technical field of coke oven gas transportation, in particular to a multi-chamber water-sealed tank for gas pipelines. Background technique [0002] The role of the gas water seal tank in the coke oven gas transportation process is mainly manifested in the following two aspects: one is to collect the condensate in the coke oven gas, to prevent the gas transportation channel from being blocked, and to ensure the continuous and stable transportation of the gas; The liquid seal formed inside the water seal tank is used to prevent gas leakage during the process of collecting coke oven gas condensate and eliminate potential safety hazards. [0003] At present, the gas water seal tanks used in coking plants are generally cylindrical vertical water seal tanks, such as the "coke oven gas water seal tank" disclosed in the Chinese patent with the authorized announcement number CN203639411U. Pipelines and cylindrical vertical water s...
