Abstract

A vertical smokeless energy-saving coal-fired boiler belongs to the technical field of solid-fuel boiler. The technical problem to be solved is to provide a vertical boiler that can fully burn coal, save energy and does not pollute the environment. The technical proposal is: the composition includes a boiler body, a grate arranged on the lower part of the boiler body, a chimney arranged on the upper end of the boiler body, and a blower and an air supply duct connected with the blower, and the improvements are that a mixed burner is levelly arranged inside the combustion chamber of the boiler body, the mixed burner is the hollow ring structure, a plurality of air inlets are arranged on the circumferential wall of the burner, and the mixed burner is connected with the air supply duct. Air from the air inlet of the mixed burner is blown to the upper surface on the coal layer inside the combustion room, so that coal can fully burn; a jet pipe arranged between the chimney and the air supply duct can effectively improve the boiler air speed so that the coal can burn more fully, not only saving energy but reducing air pollution; after flue gas is treated by a spraying dust collector, the harmful dust can effectively be prevented from entering into the atmosphere. The vertical smokeless energy-saving coal-fired boiler can be used as an industrial boiler and a civilian pot.

Description

The coal-fired vertical boiler of smoke-less power-saving

Technical field

The utility model relates to a kind of vertical boiler, and particularly the coal-fired vertical boiler of smoke-less power-saving belongs to solid-fuelled boiler technology field.

Background technology

The structure of existing vertical boiler is generally from the fire grate bottom blows.Like this, slow down because of the resistance that is subjected to the coal seam, combustion chamber makes wind speed, thereby make burning of coal insufficient.Not only cause the boiler over-emitting black exhaust, contaminated environment, and waste energy.

Summary of the invention

It is abundant that technical problem to be solved in the utility model provides a kind of coal combustion that makes, energy savings and vertical boiler free from environmental pollution.

The technical scheme that its technical problem that solves the utility model adopts is:

The coal-fired vertical boiler of a kind of smoke-less power-saving, it comprises body of heater, be loaded on the fire grate of body of heater bottom and be loaded on the chimney of body of heater upper end and hair-dryer and the air supply duct that joins with hair-dryer, its improvements are that the burning indoor horizontal of said body of heater is provided with mixing burner, mixing burner is the hollow annular structure, be provided with a plurality of blowing mouths on its peripheral wall, mixing burner and air supply duct join.

For further improving the furnace gas flow velocity, make the more abundant burning of coal, the jet pipeline is housed on the above-mentioned air supply duct, the upper end of jet pipeline joins with the chimney that is loaded on the body of heater upper end.

The coal-fired vertical boiler of above-mentioned smoke-less power-saving, the evacuation port and the spray deduster of chimney join, and enter contaminated environment in the atmosphere to prevent harmful flue dust.

The coal-fired vertical boiler of above-mentioned smoke-less power-saving, the Way out of described blowing mouth are to form angle to the top, combustion chamber with horizontal plane.

The upper surface blowing in the coal-fired vertical boiler of smoke-less power-saving provided by the utility model, the blowing mouth of its mixing burner coal seam in the combustion chamber makes coal combustion abundant; Be loaded on the jet pipeline between air supply duct and the chimney, can effectively improve the furnace gas flow velocity, make burning of coal more abundant.Like this, promptly energy savings has reduced the pollution to air again; Flue gas can prevent effectively that harmful flue dust from entering contaminated environment in the atmosphere after spray deduster is handled.This boiler both can be used as Industrial Boiler, can be used as civilian pot again.

Description of drawings

Accompanying drawing 1 is that the master of the utility model embodiment looks schematic diagram;

Accompanying drawing 2 is A-A cutaway views of Fig. 1;

Accompanying drawing 3 is I place enlarged drawings of Fig. 2;

Accompanying drawing 4 is that the B-B of Fig. 3 analyses and observe rotation diagram.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment:

Referring to accompanying drawing, the utility model comprises body of heater 5 in forming, be loaded on the fire grate 15 in the body of heater 5 and be loaded on the chimney 6 of body of heater 5 upper ends, hair-dryer 1 and the air supply duct 17 that joins with hair-dryer 1, and place air outlet 16 below the fire grate 15.Set up mixing burner 14 in the combustion chamber 3 of body of heater 5, mixing burner 14 is hollow annular, and horizontal setting is provided with a plurality of blowing mouths 2 on its peripheral wall, and mixing burner 14 joins with air supply duct 17.In order to reach best blowing effect, blowing mouth 2 to top, combustion chamber and horizontal plane shape in an angle, the angle of this angle is to guarantee that the upper surface that blowing mouth can the relative combustion coal seam is the best.In addition, flow in order to make furnace gas in the boiler can present rotation status, to improve the burning of coal effect, the Way out of blowing mouth 2 can be designed to deflection in the same way at interval, as shown in Figure 2, being provided with two outlets between the blowing mouth 2 of per two outlets for the setting that radially makes progress is the upwards blowing mouth 2 of setting of counter clockwise direction.

One jet pipeline 4 is housed on the air supply duct 17, and the upper end of jet pipeline 4 joins with the chimney 6 that is loaded on body of heater 5 upper ends, and the evacuation port of chimney 6 and a spray deduster 7 join.Be provided with deflector 8 in the deduster 7, so that the water that spray is fallen imports in the sedimentation basin 12, the suction hose 10 of water pump 9 communicates with decontamination cycle pond 11.Deduster 7 can place on the support 13, and also visual concrete condition places on the top of building.

Be provided with air quantity and regulate flashboard on air supply duct, chimney is provided with flue gas and regulates flashboard, omits not shown among the figure.
