Description
Technical Field
The utility model relates to a dry coke quenching dust removal technical field especially relates to a dust remover structure once of dry coke quenching.
Background
The coke dry quenching refers to a coke quenching method for cooling red coke by adopting inert gas. In the process of dry quenching, circulating gas is blown in from a blast cap and a conical hopper at the lower part of a cooling chamber of the dry quenching furnace, fully exchanges heat with coke, then the temperature is raised, and the coke is sent to a dry quenching waste heat boiler to produce steam. The circulating gas from the dry quenching furnace carries a large amount of dust and is corrosive; a primary dust remover is often arranged between the dry quenching furnace and the dry quenching waste heat boiler, and large granular coke powder in the circulating gas is separated by utilizing the gravity dust removal principle, so that the safe and stable operation of the dry quenching waste heat boiler is ensured, and the service life of the dry quenching waste heat boiler is prolonged.
The conventional primary dust remover can be divided into two structural forms according to whether a large retaining wall is arranged: the primary dust remover with the large retaining wall has good dust removal effect, but the large retaining wall is easy to collapse, so that the normal production is influenced; the dust removal effect of the primary dust remover without the large retaining wall is relatively poor, and the horizontal section at one end of the air inlet of the dust remover is longer, so that coke powder is easy to accumulate. Therefore, the development of a primary dust remover structure which can reduce coke powder accumulation and has good dust removal effect is urgently needed.
Disclosure of Invention
The utility model provides a structure of a coke dry quenching primary dust remover, wherein a step section arranged at the top of a dust remover body has the function of a large retaining wall and has a stable structure; the horizontal section at the inlet side is short or not arranged, so that the accumulation of coke powder can be reduced, the system resistance is reduced and the energy is saved while the coke powder separation effect is realized.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a primary dust remover structure for dry quenching comprises a dust remover body, wherein one end of the dust remover body is an air inlet, and the other end of the dust remover body is an air outlet; the bottom surface of the dust remover body consists of an inlet side horizontal section, an inlet side inclined section, an ash discharge port, an outlet side inclined section and an outlet side horizontal section in sequence from one end of the air inlet to one end of the air outlet; the outlet side horizontal section is not lower than the inlet side horizontal section, and the ash discharge port is positioned below the outlet side horizontal section and the inlet side horizontal section; the top of the dust remover body is provided with a step section; the ladder section is integrally arranged in an inclined mode, the bottom end of the ladder section is located above the ash discharging port, and the upper end of the ladder section extends towards one end of an air inlet of the dust remover body.
The step section is composed of a plurality of layers of vault structures, and the heights of all layers of vault structures are gradually reduced from one end of the air inlet to one end of the air outlet to form a staggered structure.
The length of the inlet side horizontal section is 0-500 mm.
The inclination of the outlet side inclined section is not less than that of the inlet side inclined section.
The section of the ash discharge port is circular or rectangular.
Compared with the prior art, the beneficial effects of the utility model are that:
1) simple structure is stable, and dust removal effect is good, has solved the problem that big barricade collapsed easily in the dust remover of once.
2) Effectively reduces the accumulation of coke powder at the inlet side, has smaller system resistance and is beneficial to saving energy.

Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
as shown in fig. 1 and 2, the primary dust collector structure for dry quenching of the utility model comprises a dust collector body, wherein one end of the dust collector body is an air inlet, and the other end is an air outlet; the bottom surface of the dust remover body consists of an inlet side horizontal section 2, an inlet side inclined section 3, an ash discharge port 6, an outlet side inclined section 5 and an outlet side horizontal section 4 from one end of the air inlet to one end of the air outlet in sequence; the outlet side horizontal section 4 is not lower than the inlet side horizontal section 2, and the ash discharge port 6 is positioned below the outlet side horizontal section and the inlet side horizontal section 2; the top of the dust remover body is provided with a step section 1; the whole inclined arrangement of stair section 1, its bottom is located the top of ash discharge opening 6, and the upper end of stair section 1 extends to the air intake one end of dust remover body.
The step section 1 is composed of a plurality of layers of vault structures, and the heights of all layers of vault structures are gradually reduced from one end of the air inlet to one end of the air outlet to form a staggered structure.
The length of the inlet side horizontal section 2 is 0-500 mm.
