Abstract

A smokeless and energy-saving coal-fired vertical boiler belongs to the technical field of solid fuel boilers. The technical problem to be solved is to provide a vertical boiler capable of fully burning coal, saving energy and not polluting the environment. The technical proposal is as follows: the composition includes a furnace body, a fire grate installed at the lower part of the furnace body, a chimney installed at the upper end of the furnace body, a blower and an air supply pipe connected with the blower, and the improvement is that the combustion chamber of the furnace body is horizontal. A mixing burner is provided, and the mixing burner is a hollow annular structure, and a plurality of air outlets are arranged on the surrounding wall thereof, and the mixing burner is connected with the air supply pipe. The air outlet of the mixed burner blows air to the upper surface of the coal seam in the combustion chamber to make the coal burn fully; the jet pipe installed between the air supply pipe and the chimney can effectively increase the furnace gas velocity and make the coal burn more fully. That is to save energy and reduce air pollution; after the flue gas is treated by the spray dust collector, it can effectively prevent harmful smoke and dust from being discharged into the atmosphere. It can be used not only as an industrial boiler, but also as a civil boiler.

Description

Smokeless and energy-saving coal-fired vertical boiler

technical field

The utility model relates to a vertical boiler, in particular to a smokeless energy-saving coal-fired vertical boiler, which belongs to the technical field of solid fuel boilers.

Background technique

The structure of the existing vertical boiler is generally to supply air from the bottom of the fire grate. In this way, due to the resistance of the coal seam in the combustion chamber, the wind speed is slowed down, so that the combustion of coal is not sufficient. Not only cause the boiler to emit black smoke, pollute the environment, but also waste energy.

Contents of the invention

The technical problem to be solved by the utility model is to provide a vertical boiler which can fully burn coal, save energy and not pollute the environment.

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

A smokeless energy-saving coal-fired vertical boiler, which includes a furnace body, a fire grate installed at the lower part of the furnace body, a chimney installed at the upper end of the furnace body, a blower, and an air supply pipe connected with the blower. The improvements are as follows: The combustion chamber of the furnace body is horizontally equipped with a mixed burner, which is a hollow annular structure, and a plurality of air outlets are arranged on its surrounding wall, and the mixed burner is connected with the air supply pipe.

In order to further increase the gas velocity of the furnace and make the coal burn more fully, a jet duct is installed on the above-mentioned air supply duct, and the upper end of the jet duct connects with the chimney installed on the upper end of the furnace body.

For the above-mentioned smokeless and energy-saving coal-fired vertical boiler, the emptying port of the chimney is connected with the spray dust collector to prevent harmful smoke and dust from being discharged into the atmosphere and pollute the environment.

In the above-mentioned smokeless and energy-saving coal-fired vertical boiler, the outlet direction of the tuyere is to form an included angle with the horizontal plane above the combustion chamber.

In the smokeless and energy-saving coal-fired vertical boiler provided by the utility model, the air outlet of the mixing burner blows air toward the upper surface of the coal seam in the combustion chamber, so that the coal can be fully burned; the jet pipe installed between the air supply pipe and the chimney can Effectively increase the furnace gas flow rate to make the coal burn more fully. In this way, it saves energy and reduces air pollution; after the flue gas is treated by the spray dust collector, it can effectively prevent harmful smoke from being discharged into the atmosphere and pollute the environment. The boiler can be used not only as an industrial boiler, but also as a civil boiler.

Detailed ways

Below in conjunction with accompanying drawing, the utility model will be further described by embodiment:

Referring to the accompanying drawings, the utility model comprises a body of heater 5, a grate 15 installed in the body of heater 5 and a chimney 6 mounted on the upper end of the body of heater 5, a blower 1 and an air supply duct 17 connected with the blower 1, and a set In the air supply port 16 below the fire grate 15. In the combustion chamber 3 of the furnace body 5, a mixed burner 14 is added. The mixed burner 14 is hollow and annular, and is placed horizontally. A plurality of air outlets 2 are arranged on the surrounding wall. The mixed burner 14 is connected to the air supply duct 17. . In order to achieve the best blowing effect, the air outlet 2 forms an included angle with the horizontal plane above the combustion chamber, and the angle of the included angle is optimal to ensure that the air outlet can be relatively to the upper surface of the burning coal bed. In addition, in order to make the furnace gas in the boiler flow in a rotating state to improve the combustion effect of coal, the outlet direction of the tuyere 2 can be designed to deflect in the same direction at intervals. As shown in Figure 2, every two outlets are radial Between the blowing ports 2 arranged upwards, there are two blowing ports 2 whose outlets are arranged upwards in a counterclockwise direction.

A jet duct 4 is housed on the air supply duct 17, and the upper end of the jet duct 4 joins with the chimney 6 that is contained in the body of heater 5 upper ends, and the emptying port of the chimney 6 joins with a spray dust collector 7. A deflector 8 is provided in the dust remover 7, so that the water falling from the spraying is introduced into the sedimentation tank 12, and the water suction pipe 10 of the water pump 9 communicates with the purification circulation pool 11. Dust remover 7 can be placed on the support 13, also can be placed on the top of building according to specific conditions.

An air volume regulating shutter is provided on the air supply duct, and a flue gas regulating shutter is provided on the chimney, which are not shown in the figure.
