Multifunctional closed tar residue collecting device and method

Abstract

The invention discloses a multifunctional closed tar residue collecting device, which comprises a tar residue collecting tank; a waste gas collecting pipeline is arranged at one end of the top plane of the tar residue collecting tank; a tar residue inlet pipeline is arranged at the other end far away from the waste gas collecting pipeline; a stirring part is arranged at the top of the tar residuecollecting tank and located between the waste gas collecting pipeline and the tar residue inlet pipeline; a heating part is arranged at the bottom in the tar residue collecting tank; a screening partis arranged on the inner side wall of the tar residue collecting tank; and a cutting part used for cutting tar residues is arranged in the tar residue inlet pipeline. By adopting the technical scheme,a traditional open-type tar residue collecting device is abandoned; closed tar residue collection is adopted, direct emission of toxic and harmful gas such as ammonia gas, hydrogen cyanide, phenols,hydrogen sulfide and benzopyrene is avoided, the device is more environmentally friendly, the closed device is beneficial for the personal health of workers in a working environment, and the device body is simple in structure, easy to operate and low in required cost.

Description

technical field [0001] The invention belongs to the field of coking, and more specifically, the invention relates to a multifunctional closed-type tar residue collecting device and a collecting method. Background technique [0002] In the process of coking production, high-boiling organic compounds will be condensed to form coal tar. At the same time, coal powder, semi-coke and other mixtures entrained in the gas are also mixed with the coal tar to form lumps of different sizes. The oil residue is called tar residue; the tar residue is mainly scraped out through the mechanized clarifier and then enters the collection tank. The oil residue contains a mixture of about 30% coal tar, 60% ammonia water and 10% residue, which is in a semi-fluid state as a whole. The tar residue collection device of the company is open, and the environment at the collection site is very harsh, and the generated gases such as ammonia, hydrogen cyanide, phenols, hydrogen sulfide and benzopyrene will ...

Problems solved by technology

[0002] During the coking production process, organic compounds with high boiling points will be condensed to form coal tar. At the same time, the mixture of coal powder and semi-coke entrained in the gas is also mixed in the coal tar to form lumps of different sizes. These lumps The shape is called tar residue; the tar residue is mainly scraped out through the mechanized clarification tank and then enters the collection tank. The oil residue contains a mixture of about 30% coal tar, 60% ammonia water and 10% slag, and is in a semi-fluid state as a whole. Traditional The tar slag collection device is open, and the environment at the collection site is very harsh, and the generated gases such as ammonia, hydrogen cyanide, phenols, hydrogen sulfide and benzopyrene will cause serious air pollution; at the same time, during the collection process There are risks such as running, risking, dripping and leaking, and there are great environmental protection hazards
