Anti-clogging type water seal device for coke oven gas conveying pipeline

Abstract

The invention discloses an anti-clogging type water seal device for a coke oven gas conveying pipeline. The anti-clogging type water seal device comprises a gas pipeline, an oil drain pipe and a water seal tank, wherein the water seal tank is positioned right under the gas pipeline, the oil drain pipe is communicated with the gas pipeline and the water seal tank, a main valve is connected into the oil drain pipe, a heating pipeline is arranged at the lower side of the gas pipeline adjacent to the oil drain pipe, the heating pipeline is wound on the outer side of the oil drain pipe, and an overflow port is arranged in the upper part of the water seal tank. The anti-clogging type water seal device provided by the invention is particularly applicable to a gas pipeline with serious residue accumulation, and the water seal device adopts the oil water separation principle as the core technology, so that the oil and residues are effectively separated, and the residual oil is prevented from slagging and clogging a water drain outlet. The anti-clogging type water seal device is applicable to various toxic and harmful gas pipeline networks such as gas pipelines, and has better environmental-protection benefit and social benefit.

Description

technical field [0001] The invention provides a kind of gas pipeline that can be widely used in iron and steel, coking, chemical industry with serious slag accumulation or non-slagging gas pipeline for oil drainage and drainage, including gas pipelines such as coke ovens, blast furnaces, converters, generators, and toxic gas pipelines. , Slag discharge, oil drainage and water drainage of harmful gas pipelines. Background technique [0002] In the metallurgical industry, especially the coking industry, coke oven gas contains a large amount of naphthalene, tar, ammonia water and other substances. These substances will accumulate at the bottom of the gas pipeline during the coke oven gas purification and transportation process, resulting in unsafe transportation of the gas. Generally, drainers are used (Gas water seal) to discharge the condensate in the gas, and this traditional gas water seal can only discharge the condensate in the gas pipeline, and the viscous residue such a...

[0002] In the metallurgical industry, especially the coking industry, coke oven gas contains a large amount of naphthalene, tar, ammonia water and other substances. These substances will accumulate at the bottom of the gas pipeline during the coke oven gas purification and transportation process, resulting in unsafe transportation of the gas. Generally, drainers are used (Gas water seal) to discharge the condensate in the gas, and this traditional gas water seal can only discharge the condensate in the gas pipeline, and the viscous residue such as asphalt in the pipeline cannot be discharged smoothly, and it is often blocked, not only Difficult to clean, also affects the safe operation of the gas pipeline network
