Description

The utility model relates to the field of environmental protection and can be used in the purification of gas emissions from hydrogen sulfide in the chemical and petrochemical enterprises.

The closest technical solution to the proposed utility model is an adsorber for cleaning flue gases from nitrogen oxides and sulfur, including a cylindrical body with pipes for supplying the source, removal of the purified gas mixture and pipe for removing the sorbent with absorbed oxides of nitrogen and sulfur. The adsorber is filled with a fixed bed of adsorbent, which is used as a dry sludge chemical treatment. [Utility Model No. 120371, IPC B01D 53/04 (2006.1), publ. 09/20/2012, Bull. No. 26].

The disadvantage of the known adsorber is the lack of regeneration of the adsorbent. Sludge with absorbed oxides of nitrogen and sulfur is removed from the adsorber through the pipe outlet of the sorbent.

The technical result of the utility model is the development of an adsorber for cleaning gas emissions from hydrogen sulfide, in which the shortcomings of the prototype are eliminated.

The technical result is achieved due to the fact that the adsorber for cleaning gas emissions from hydrogen sulfide, comprising a housing with a fixed bed of sorbent placed in it, a gas supply pipeline and a pipeline for discharging purified gases, according to the claimed utility model, additionally introduced a compressed air supply pipeline to regenerate the adsorbent , a regeneration exhaust gas pipeline with absorbed hydrogen sulfide, and a sorbent in the form of a dry granulated adsorption material based on a chemical water cleaning sludge is placed Between steel meshes with a hole size of not more than 1 mm.

The essence of the utility model is illustrated in the drawing, which shows the proposed adsorber for cleaning gas emissions from hydrogen sulfide.

The numbers on the drawing are:

1 - gas exhaust pipeline;

2 - housing;

3 - a layer of dry GASM;

4 - steel mesh with holes with a diameter of not more than 1 mm;

5 - diffusion spray

6 - gas supply pipeline

7 - pipeline for gas recovery;

8 - compressed air supply line.

The difference of the proposed adsorber is that it introduces a pipeline 7 of the regeneration gas outlet with absorbed hydrogen sulfide, and a layer of dry GASM 3 is placed on a steel grid 4 with openings not exceeding 1 mm. On top of the GASM there is an identical steel mesh 4 for preventing the removal of its particles during regeneration. Regeneration is carried out by compressed air through the pipeline 8.

Adsorber for cleaning gas emissions from hydrogen sulfide works as follows. Gas emissions come through pipe 6 into the body 1 of the adsorber. Next, they pass through a fixed bed of sorbent 3, which used dry GASM, where they are cleaned from hydrogen sulfide.

The purified gas is discharged through pipe 1. Pipeline 6 is connected to a diffusion atomizer 5, which ensures uniform distribution of gases over a fixed bed of dry GASM 3 placed on a steel mesh 4.

Spent dry GASM with absorbed hydrogen sulfide is regenerated by compressed air entering the body through pipeline 8. To prevent sorbent particles from escaping, steel mesh 4 is placed on top of it. Regeneration gas is discharged through pipeline 7.

The use of the utility model will allow for a high intensity of cleaning gas emissions from hydrogen sulfide and reducing the cost of cleaning due to the regeneration of dry (moisture 20%) GASM used in the adsorber as a sorbent based on chemical water cleaning sludge from thermal power plants. Regeneration is ensured by the presence of a compressed air supply pipeline and a steel mesh above the GASM.
