Description

Novel gravity barricade that once removes dust of dry coke quenching

Technical Field

The utility model relates to a gravity dust collecting equipment technical field especially relates to a novel gravity barricade that once removes dust of dry coke quenching.

Background

A primary dust remover for coke dry quenching belongs to gravity dust removal, and adopts a suspension type neutral retaining wall, and the principle is that large-particle coke powder in circulating gas is separated by the retaining wall, so that the scouring abrasion of the coke powder in the circulating gas to a boiler tube (mainly a secondary superheater pipeline) of a boiler system is reduced, and the purpose of protecting the boiler tube is achieved.

However, the suspension type gravity retaining wall for once dedusting of coke dry quenching has the disadvantages of complex masonry process, high cost, short service life, easy collapse due to structural problems, shutdown treatment after collapse, and influence on long-term stable operation of coke dry quenching.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a novel dry coke quenching once removes dust gravity barricade solves the short-lived problem of suspension type gravity barricade.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the utility model relates to a novel coke dry quenching once dust removal gravity retaining wall, which comprises an upper wall body of a dust removal chimney, wherein a crossbeam is arranged inside the upper wall body, a vertical beam is welded at the lower end of the crossbeam, a first retaining wall is arranged around the vertical beam, and the first retaining wall is positioned at the lower end of the upper wall body; a first lower wall body section is arranged below the first retaining wall, a second lower wall body section is arranged on the right side of the first lower wall body section, and a blanking hopper is arranged between the first lower wall body section and the second lower wall body section; and a second retaining wall is arranged at the upper end of the lower wall body section II.

Furthermore, the vertical beam is of an inverted T-shaped structure.

Further, the lower wall body section one is slightly lower than the lower wall body section two.

Furthermore, the first retaining wall and the second retaining wall are built by insulating bricks.

Furthermore, the cross beam and the vertical beam are both of stainless steel structures.

Compared with the prior art, the utility model discloses a beneficial technological effect:

the utility model discloses a novel dry coke quenching once dust removal gravity barricade is different from traditional dry coke quenching once dust removal suspension type gravity barricade, divides the suspended gravity barricade into two parts and sets up respectively in the both sides of blanking fill, wherein, left gravity barricade hangs on the upper wall body through stainless steel vertical beam, and self gravity is less, and the volume is less, and the joint strength between and the upper wall body is big, has lengthened its life; the second retaining wall on the other side is positioned on the lower wall body, and the volume of the second retaining wall is smaller than that of the suspended gravity retaining wall. The smoke dust of dry quenching firstly runs downwards under the action of the first retaining wall, most of large-particle coke powder falls from the hopper under the action of the first retaining wall through self gravity, a small part of small-particle coke powder falls from the hopper under the action of the second retaining wall, and the smoke gas passes through the second retaining wall to complete the dust removal process. In a word, the utility model discloses dry coke quenching once removes dust gravity barricade dust removal effect is good, builds simple process by laying bricks or stones, the material is few, with low costs, long service life, and the operation is stable.

Drawings

The present invention will be further explained with reference to the following description of the drawings.

FIG. 1 is a schematic view of the structure of the novel dry quenching primary dedusting gravity retaining wall of the utility model;

description of reference numerals: 1. an upper wall body; 2. a cross beam; 3. a first retaining wall; 4. erecting a beam; 5. a first lower wall body section; 6. feeding a hopper; 7. a second lower wall section; 8. and a second retaining wall.

Detailed Description

As shown in figure 1, a novel gravity retaining wall of once removing dust of dry quenching, last wall body 1 including the dust removal chimney, it has crossbeam 2 to go up wall body 1 internally mounted, the lower extreme welding of crossbeam 2 has perpendicular roof beam 4, crossbeam 2 and perpendicular roof beam 4 are stainless steel construction, can improve joint strength.

Erect roof beam 4 and be the type structure of falling T, its periphery is enclosed to be built and is had first barricade 3, improves first barricade 3's use intensity, increase of service life. The first retaining wall 3 is positioned at the lower end of the upper wall body 1 and is in a vertical state. Wall body section one 5 is installed down to the below of first barricade 3, wall body section two 7 is installed down on the right side of wall body section one 5 down, wall body section one 5 is slightly less than wall body section two 7 down, can be better for the flue gas that has the fine coke like this. And a lower hopper 6 is arranged between the first lower wall body section 5 and the second lower wall body section 7, and the lower hopper 6 is used for coke powder to fall. And a second retaining wall 8 is arranged at the upper end of the second lower wall body section 7, and secondary blocking is carried out on the coke powder to enable the coke powder to fall, so that the dust removal purpose is achieved.

The first retaining wall 3 and the second retaining wall 8 are all built by adopting heat insulation bricks.

The utility model discloses an operation process as follows:

firstly, the smoke dust with coke powder moves from the first position 5 of the lower wall body section to the second position 7 of the lower wall body section, the smoke dust moves downwards under the action of the first retaining wall 3, and the coke powder with larger particles falls from the blanking hopper 6 under the action of self gravity; then, the coke powder with smaller particles falls down to the lower hopper 6 under the action of the second retaining wall 7 and the self gravity, and the dust removal is finished; and finally, discharging the dedusted flue gas from an outlet above the second retaining wall 7.

The above-mentioned embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and those skilled in the art should also be able to make various modifications and improvements to the technical solution of the present invention without departing from the spirit of the present invention, and all such modifications and improvements are intended to fall within the scope of the present invention as defined in the appended claims.
