The utility model relates to a pulverized coal fire injection system. The pulverized coal fire injection system includes a pulverizer, a storage tank, a fan, and a burner. The pulverizer is connected to the storage tank through a feeding pipe, the air inlet of the fan is connected to the upper end of the storage tank through the air supply pipe, and the air outlet of the fan is connected through the feeding pipe. It communicates with the air duct of the burner, the air duct communicates with the inside of the burner through several holes, and the bottom end of the storage tank communicates with the feeding pipe. The utility model is easy to use, the coal is pulverized into coal powder by the pulverizer, and the particle size of the coal powder can be controlled by the wind speed and air volume, and the size of the flame can be adjusted at any time, which improves the surface area of the coal, and the coal powder is mixed with the air by the fan to ensure that the coal powder Oxygen supply required for combustion, so that the pulverized coal can be completely burned, so as to make full use of the heat energy generated by complete combustion, improve the utilization efficiency of coal, and reduce pollution emissions. The utility model can also use combustible solids such as charcoal as fuel.
Description
Technical field
The utility model relates to a kind of coal dust flame system.
Background technology
China is that a few is one of country of main primary energy with coal in the world; Traditional coal mode of using, coal is in combustion process, because its chemically incomplete combustion and physics imperfect combustion; And cause burning of coal efficient low; Cause the industrial products energy consumption high, efficiency of energy utilization is low, and causes serious atmosphere pollution.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of coal completing combustion that makes is provided, thereby improves coal burning efficient, reduces the coal dust flame system that pollutes.
The technical scheme of the utility model is:
Coal dust flame system; Comprise pulverizer, holding vessel, blower fan, also comprise burner, pulverizer is communicated with holding vessel through feeder sleeve; The air inlet of blower fan is communicated with the holding vessel upper end through ajutage; The air outlet of blower fan is through the air channel of feed pipe connection burner, and the air channel is through some holes and burner internal communication, and the bottom of holding vessel is communicated with feed pipe.
Concrete, the bottom of holding vessel is provided with the solid flow controller, can control pulverized coal flow at any time.
Concrete, one deck flame retardant coating is set on the inwall of burner.
Concrete, some ventilating openings are set on the flame retardant coating burner.
The beneficial effect of the utility model is: the utility model is easy to use, and coal is ground into coal dust through pulverizer, and can be through wind speed air quantity control pulverized coal particle size; Can regulate flame size at any time, improve the surface area of coal, coal dust mixes with air through blower fan; The supply of required oxygen when having guaranteed coal dust firing; Thereby make the coal dust can completing combustion,, improve the utilization ratio of coal to make full use of the heat energy that completing combustion is produced; And having reduced discharge amount of pollution, the utility model can also act as a fuel with burnable solids such as charcoals.
Description of drawings
Fig. 1 is the utility model moth structural representation.
1 pulverizer, 2 holding vessels, 3 blower fans, 4 burners, 5 ventilating openings
6 solid flow controllers, 7 feeder sleeves, 8 ajutages, 9 feed pipes, 10 flame retardant coatings
11 air channels.
The specific embodiment
Coal dust flame system comprises pulverizer 1, holding vessel 2, blower fan 3, also comprises burner 4; Pulverizer 1 is communicated with holding vessel 2 through feeder sleeve; The air inlet of blower fan 3 is communicated with holding vessel 2 upper ends through ajutage 8, and the air outlet of blower fan 3 is through the air channel 11 of feed pipe 9 connection burners 4, and it is inner that air channel 11 is communicated with burner through 8 holes; The bottom of holding vessel 2 is communicated with feed pipe 9, and the bottom of holding vessel 2 is provided with the solid flow controller.
One deck flame retardant coating 10 is set on the inwall of burner 4, ventilating opening 5 is set on the burner 4.
Should be noted that at last: above embodiment only in order to the explanation the utility model technical scheme but not to its restriction; Although with reference to preferred embodiment the utility model has been carried out detailed explanation, the those of ordinary skill in affiliated field is to be understood that: still can make amendment to the specific embodiment of the utility model perhaps is equal to replacement to the part technical characterictic; And not breaking away from the spirit of the utility model technical scheme, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
