Description

Fully mixed biomass fuel combustor

Technical Field

The utility model belongs to the technical field of the combustor, concretely relates to intensive mixing biomass fuel combustor.

Background

China is a big agricultural country, the crop straw yield is about 7 hundred million tons/year, and the crop straw is at the first position in the world. At present, the main uses of the straws in China are paper making, feed and rural domestic energy (used as fuel), a part of the straws are returned to the field for fertilizer production, and the rest straws are discarded or burned to become wastes which are not used much but need to be disposed. In summer and autumn and winter every year, a large amount of straws of wheat, corn and the like are incinerated in the field, a large amount of dense smoke is generated, the problem becomes a bottleneck problem of rural environment protection, even becomes a main cause of the vicious city environment, and becomes a new source of rural pollution. With the development of economy, the primary energy supply is increasingly tense, and the biomass energy is regarded as renewable, storable and transportable biomass energy. The biomass energy has various types and complex shapes, and can be normally used in a large scale after being processed. In the prior art, the biomass gas needs sufficient air distribution and mixing to be burnt out, however, the traditional combustor body is unreasonable in design, and the fuel gas is not sufficiently combusted in the combustor.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model provides a following technical scheme: the utility model provides a intensive mixing biomass fuel combustor, includes the combustor casing, be equipped with the combustion chamber in the combustor casing, combustor casing top is equipped with combustion-supporting air vent, the left side of combustor casing is equipped with the combustor export, and its right side still is equipped with the gas breather pipe, the gas breather pipe is deepened the combustion chamber inside and is connected with the cyclone adapter, be connected with rotatable cloth wind dish on the cyclone adapter, be equipped with a plurality of air vents on the cloth wind dish, one side that the gas breather pipe was kept away from to the cyclone adapter still fixedly is equipped with the baffle.

Furthermore, one half of the vent holes on the air distribution plate are declined along the direction of the fuel gas, and the other half of the vent holes on the air distribution plate are declined along the direction of the fuel gas.

Further, the air distribution plate is in a windmill shape.

Furthermore, a filter screen is arranged at the pipe orifice of the combustion-supporting air vent.

Further, the baffle, the cyclone joint and the gas vent pipe are on the same horizontal axis.

The utility model has the advantages that: can realize the intensive mixing of gas and combustion-supporting gas for the burning is more abundant, and the combustion effect is better.

fig. 2 is a structural view of the air distribution plate of the present invention.

In the figure: 1. a burner housing; 2. a combustion chamber; 3. a combustion-supporting vent; 4. a burner outlet; 5. a gas vent pipe; 6. a cyclonic adapter; 7. an air distribution plate; 8. a vent hole; 9. a baffle plate; 10. and (5) filtering by using a filter screen.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1-2, a burner for fully mixing biomass fuel comprises a burner housing 1, a combustion chamber 2 is arranged in the burner housing 1, a combustion-supporting air vent 3 communicated with the internal combustion chamber 2 is arranged on the burner housing 1, combustion-supporting gas enters the combustion chamber 2 through the combustion-supporting air vent 3, a gas vent pipe 5 is arranged on the right side of the burner housing 1 and is responsible for introducing gas, the gas vent pipe 5 extends into the combustion chamber 2 and is connected with a cyclone adapter 6, a rotatable air distribution plate 7 is connected to the cyclone adapter 6, the air distribution plate 7 is windmill-shaped and is provided with a plurality of vent holes 8, after introducing gas from the gas vent pipe 5, the gas enters the air distribution plate 7 through the cyclone adapter 6 and is sprayed out from the vent holes 8 of the air distribution plate 7, the direction of half of the vent holes 8 in the air distribution plate 7 inclines downwards, and the direction of the other half of the vent holes 8, the air vent 8 can be inclined left and right besides up and down, and the purpose is to form a convection current when the fuel gas is blown out, so that the fuel gas and the combustion-supporting gas are mixed more fully, the air distribution disc 7 in the embodiment is designed to be in a windmill shape, the fuel gas can be sprayed out from the air distribution disc 7, the air distribution disc 7 can rotate under the action of the air flow due to the specific structure, so that the fuel gas and the combustion-supporting gas are fully mixed, and the fuel gas is pre-combusted.

The use principle of the embodiment is as follows: firstly, combustion-supporting gas is sent into the combustion chamber 2 through the combustion-supporting air vent 3, the filter screen 10 of the combustion-supporting air vent 3 can filter the combustion-supporting gas, the combustion-supporting gas enters the combustion chamber 2 and reaches the air distribution disc 7, the gas is sent into the combustion chamber 2 through the gas vent pipe 5, the gas is sprayed to the combustion chamber through the vent holes 8 on the air distribution disc 7, meet the baffle 9, the gas is diffused all around, the air distribution disc 7 can rotate along with the action of the gas flow, the sufficient mixing of the gas and the combustion-supporting gas can be realized, the pre-combustion is carried out, the low-heat-value gas can further fully combust after the pre-combustion, and the combustion.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
