The retaining wall is a non-suspended structure built on the flue, so that the retaining wall is not easy to damage, the service life of the dust removal device is prolonged, the long-period stable operation of the coke dry quenching device is ensured, the production efficiency of the coke dry quenching system is improved, the maintenance cost and the operation cost are reduced, and the flue on the upper part of the retaining wall is provided with the flue bulge, so that the resistance of high-temperature inert gas passing through the retaining wall is effectively reduced when the high-temperature inert gas coming out of the annular flue of the coke dry quenching furnace passes through the curved flue formed by the bulge.
Description
Technical Field
The utility model relates to a dry coke quenching technical field, concretely relates to dry quenching stove dust collector.
Background
The dry quenching is to load red coke from the top of a dry quenching furnace, low-temperature inert gas is blown into a red coke layer of a cooling section of the dry quenching furnace by a circulating fan to absorb sensible heat of the red coke, the cooled coke is discharged from the bottom of the dry quenching furnace, high-temperature inert gas discharged from an annular flue of the dry quenching furnace flows through a dry quenching process boiler to carry out heat exchange, the boiler generates steam, the cooled inert gas is blown into the dry quenching furnace again by the circulating fan, and the inert gas is recycled in a dry quenching closed system. The dry quenching process is superior to wet quenching in energy saving, environment protection, coke quality improvement and other aspects.
In the prior domestic coke dry quenching process, a primary dust remover with a middle retaining wall structure is generally adopted for primary separation of solid particles such as coke powder in circulating inert gas, two ends of the primary dust remover are respectively connected with a coke dry quenching furnace and a boiler, and after the circulating inert gas from the coke dry quenching furnace is blocked by a gravity retaining wall, the coke powder mixed in the circulating gas falls into an ash bucket under the action of gravity due to the reduction of the speed.
FIG. 1 is a schematic structural diagram of a primary dust remover of a currently domestic dry quenching furnace. The main components and structures of the coke dry quenching device are a gravity suspension retaining wall 4 with an arch structure suspended in a flue and a coke breeze discharge hopper 3, the coke breeze discharge hopper 3 is connected at the lower end of the flue 5, and the gravity suspension retaining wall 4 is a suspension structure erected between two side walls, so that the retaining wall 4 is easy to collapse in the production process, the normal production operation of coke dry quenching is influenced, the overhaul period of a dust remover is shortened, and the maintenance and operation cost is increased.
Disclosure of Invention
The utility model provides a dust removal device for dry quenching furnace to overcome the defects in the prior art.
The primary dust removal device for the dry quenching furnace is realized by adopting the following technical scheme:
the primary dust removal device for the dry quenching furnace comprises a dust collecting groove arranged under a flue, wherein the two ends of the flue are respectively provided with an air inlet connected with an air outlet of the dry quenching furnace and an air outlet connected with an air inlet of a boiler.
The top of the retaining wall is not lower than the upper flue surface of the flue.
The cross section of the transverse protrusion is trapezoidal, and the height of the transverse protrusion is 200-300 mm.
The height of the flue bulge is 50-80% of the height of the flue.
The utility model has the advantages that:
the retaining wall is arranged at the edge of the dust collecting groove at the gas outlet end of the dust collecting groove, namely the gas outlet side connected with the gas inlet of the boiler, namely the retaining wall is of a non-suspended structure built on the flue, so that the retaining wall with the non-suspended structure is not easy to damage, the service life of the dust removal device is prolonged, the long-period stable operation of the coke dry quenching device is ensured, the production efficiency of the coke dry quenching system is improved, and the maintenance cost and the operation cost are reduced. Secondly, a transverse bulge facing to the direction of the air outlet of the dry quenching furnace is formed at the top end of the left side wall of the retaining wall, and raised coke dust is blocked at the transverse bulge, quickly settled after the flow speed is reduced and is not easy to be brought out along with air flow, so that the dust removal effect is improved. And thirdly, because the flue at the upper part of the retaining wall is provided with the flue bulge, the passing resistance of the high-temperature inert gas is effectively reduced when the high-temperature inert gas coming out of the annular flue of the dry quenching furnace flows through the curved flue formed by the bulge after meeting the retaining wall.

FIG. 1 is a schematic structural diagram of a primary dust removal device of a conventional dry quenching furnace.
Fig. 2 is a schematic structural diagram of the present invention.
In the figure: 1. the air-conditioning device comprises an air inlet, 2 an air outlet, 3 a dust collecting groove, 4 a suspended retaining wall, 5 a flue, 6 a retaining wall, 7 a flue bulge and 8 a retaining wall bulge.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in figure 2, the primary dust removing device for the dry quenching furnace comprises a dust collecting groove 3 arranged below a flue 5, wherein both ends of the flue 5 are respectively provided with a dust removing device air inlet 1 connected with an air outlet of the dry quenching furnace and a dust removing device air outlet 2 connected with an air inlet of a boiler, the right end of the dust collecting groove 3 is provided with a retaining wall 6, the retaining wall 6 is rectangular, the rectangular retaining wall 6 is built at the left end of the air outlet 2 of the dust removing device, a transverse bulge 9 towards the air inlet 1 of the dust removing device is formed at the top end of the left side wall of the retaining wall 6, the cross section of the transverse bulge 9 is trapezoidal, the height h of the transverse bulge 9 is 200-300 mm, an upward flue bulge 8 is formed in the flue 5 at the upper part of the retaining wall 6, the top of the retaining wall 6 is not lower than the upper flue surface 7 of the flue 5, the flue 5 forms a bent flue by the retaining wall 6 and the flue bulge 8, and the height of the flue bulge 8 is 50-80% of the height of the flue.
