Abstract
The utility model relates to a coal dust flaming system. The coal dust flaming system comprises a grinder, a storage tank, a fan and a combustor, wherein the grinder is communicated with the storage tank through a supply pipe; an air inlet of the fan is communicated with the upper end of the storage tank through a blast pipe; an air outlet of the fan is communicated with an air duct of the combustor through a feed pipe; the air duct is communicated with the inside of the combustor through a plurality of holes; and the bottom of the storage tank is communicated with the feed pipe. The system is convenient to use, coal is ground into coal dust by the grinder, the size of coal dust particles can be controlled through air speed and air volume, the size of flame can be adjusted at any time, and the surface area of the coal is increased; and the coal dust is mixed with air through the fan, and the supply of oxygen required during combustion of the coal dust is ensured, so that the coal dust can combust completely, heat energy generated during complete combustion is fully utilized, the utilization efficiency of the coal is improved, and the pollutant discharge is reduced. In addition, combustible solids such as wood charcoal can be used as fuels.
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.
