Abstract

The utility model relates to an ash dropping groove of a civil clean coal heating furnace, which is arranged at the bottom of an air chamber at the lower part of a grate and has a drawer type structure; a layer of ash breaking net is arranged in the ash falling groove, and the mesh aperture of the ash breaking net is smaller than the size of ash after the molded coal is combusted; cooling water is contained in the ash falling groove, and the ash breaking net is positioned below the water surface of the cooling water; an ash pouring opening is reserved between the front end edge of the ash breaking net and the front end wall of the ash falling groove. When the high-temperature coal ash falls down, the high-temperature coal ash falls onto the ash breaking net in a large-block particle state, the large-block particle ash is gradually immersed into cooling water and gradually explodes to become small-particle ash, and the small-particle ash falls into water in the ash falling groove through the ash breaking net; meanwhile, high-temperature water vapor generated by cooling the high-temperature ash falling water reacts with high-temperature carbon particles to generate carbon monoxide and hydrogen, and the carbon monoxide and the hydrogen enter a hearth to strengthen the combustion of clean coal. The utility model discloses raise dust and conflagration when not only avoiding the heating stove to fall the ash can also improve the burning of clean moulded coal, reinforcing carbon combustion efficiency, fuel saving.

Description

Ash chute for civil clean coal heating stove

Technical Field

The utility model relates to a civil clean coal heating furnace, in particular to an ash falling groove of a civil clean coal heating furnace.

Background

The existing clean coal heating furnace is provided with an ash hopper at the bottom of an air chamber at the lower part of a grate, ash after fuel combustion directly falls into the ash hopper, dust rises to pollute the environment when ash is removed outwards, the ash is not well cooled, and fire disasters are easily caused when the ash is poured.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to provide a civil clean coal heating furnace ash chute with water containing structure.

The utility model provides a technical scheme that its technical problem adopted is:

an ash falling groove of a civil clean coal heating furnace is arranged at the bottom of an air chamber at the lower part of a grate and has a drawer type structure; a layer of ash breaking net is arranged in the ash falling groove, and the mesh aperture of the ash breaking net is smaller than the size of ash after the molded coal is combusted; cooling water is contained in the ash falling groove, and the ash breaking net is positioned below the water surface of the cooling water; an ash pouring opening is reserved between the front end edge of the ash breaking net and the front end wall of the ash falling groove.

Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, beneficial effect is:

when the high-temperature coal ash falls down, the high-temperature coal ash falls onto the ash breaking net in a large-block particle state, the large-block particle ash is gradually immersed into cooling water and gradually explodes to become small-particle ash, and the small-particle ash falls into water in the ash falling groove through the ash breaking net; meanwhile, high-temperature water vapor generated by cooling the high-temperature ash falling water reacts with high-temperature carbon particles to generate carbon monoxide and hydrogen, and the carbon monoxide and the hydrogen enter a hearth to strengthen the combustion of clean coal. The utility model discloses raise dust and conflagration when not only avoiding the heating stove to fall the ash can also improve the burning of clean moulded coal, reinforcing carbon combustion efficiency, fuel saving.

Drawings

Fig. 1 is a schematic view of an installation position of an embodiment of the present invention;

fig. 2 is a schematic structural diagram of an embodiment of the present invention;

FIG. 3 is a top view of FIG. 2;

in the figure: a grate 1; an air chamber 2; an ash falling groove 3; a hearth 4; a handle 301; a trough 302; an ash breaking net 303; a water surface 304; an ash pouring port 305; and a mesh 306.

Detailed Description

The invention will be further explained with reference to the following embodiments shown in the drawings.

Referring to fig. 1, 2 and 3, an ash dropping groove 3 of the clean coal heating furnace for civil use according to the present embodiment is disposed at the bottom of an air chamber 2 at the lower part of a fire grate 1, and a handle 301 is disposed at the front end of a groove body 302 of the ash dropping groove 3 to form a drawer type push-pull structure; a layer of ash breaking net 303 is arranged in the groove body 302 of the ash falling groove 3, and the caliber of meshes 306 of the ash breaking net 303 is smaller than the size of ash after the briquette is combusted; cooling water is contained in the ash falling groove 3, and the ash breaking net 303 is positioned below the water level 304 of the cooling water; an ash pouring port 305 is reserved between the front end edge of the ash breaking net 303 and the front end wall of the groove body 302 of the ash dropping groove 3.

When the heating furnace is used, the molded coal in the hearth 4 is combusted, large blocks of molded coal ash particles fall onto the ash breaking net 303 from the fire grate 1, the ash breaking net 303 is positioned below the water surface 304 and close to the water surface 304, the large blocks of molded coal ash particles cannot be immersed by water once but are gradually wetted, and the wetted part is firstly split into small particles of ash and falls into the water in the ash falling groove 3 through the ash breaking net 303; meanwhile, high-temperature water vapor generated by cooling the high-temperature ash falling water reacts with high-temperature carbon particles to generate carbon monoxide and hydrogen, and the carbon monoxide and the hydrogen enter the hearth 4 to strengthen the combustion of clean coal.

The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all structural equivalents made by using the contents of the specification and drawings are included in the scope of the present invention.
