Description

Coal-turned-gas boiler coal gas mixing tube

Technical field

The utility model relates to field of boilers, particularly coal-turned-gas boiler coal gas mixing tube.

Background technology

In the explored minable energy resource structure of China, according to country 2015 directiveness consume index, various fuel source can be limited to coal year 360 years, oil was less than 5 years, and natural gas was less than 16 years.In coal resources, brown coal account for 41.18%, and wherein 75% in Middle Eastern, Inner Mongol.The active boiler of China is based on fire coal, have a large capacity and a wide range, along with social productive forces development and scientific and technological progress, great changes have taken place for boiler combustion equipment, but combustion system is still based on layer combustion and fluidized bed combustion, and the flue dust of these two kinds of combustion system post combustion emission, sulfur dioxide, nitrogen oxide are very high, be the major pollutants of air, therefore improve burning of coal and just seem very important.

Coal-turned-gas boiler is the New-type boiler occurred in recent years, and in improvement burning of coal, in reduction pollutant emission, effect clearly.Coal-turned-gas boiler lot of advantages, first coal-turned-gas boiler is by the lower brown coal design of calorific capacity, aboundresources; Secondly coal-turned-gas boiler efficiency of combustion is high, has saved valuable resource; Coal-turned-gas boiler flue dust and toxic and harmful discharge extremely low again, protect environment greatly; But blemish in an otherwise perfect thing is that coal-turned-gas boiler is difficult to fully perplexed by burning, thus market is badly in need of a kind of device solving coal-turned-gas boiler Thorough combustion problem, thus lay a good foundation for the popularization of coal-turned-gas boiler.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of coal gas mixing tube that can make coal-turned-gas boiler sufficient combustion.

The technical solution of the utility model is as follows:

Coal-turned-gas boiler coal gas mixing tube, be made up of pipe, mixing outer tube and mixture gas nozzle in mixing, mixing outer tube sleeve is in mixing on pipe, in mixing, pipe forms air between outer tube and presss from both sides chamber with mixing, in mixing, pipe side arranges gas entry, mixing outer tube side is fixedly connected with mixture gas nozzle, and mixing outer tube arranges air introducing port, the interior pipe of mixing is arranged rotatingly penetrate sucker.

The injecting tube of pipe to be internal diameter be gradually closing in mixing.

Described air introducing port becomes 60 degree of angles with mixing outer tube axis.

The utility model has the advantage of:

1, structure is simple, and be convenient to the popularization manufacturing and be conducive to these parts, economic benefit is huge; 2, the air be blown into by pipe in mixing and mixing outer tube and the mist of coal gas mix in the mixture gas nozzle of flaring, because nozzle is flaring, the gas velocity at flow nozzle angle reduces, be conducive to the abundant mixing of two kinds of gases, improve burning quality, after air is fully mixed with coal gas, be blown into burner hearth ignition combustion.。

Description of drawings 1 is the utility model overall structure schematic diagram;

Fig. 2 is pipe front view in the utility model mixing;

Fig. 3 is pipe left view in the utility model mixing;

Fig. 4 is the utility model mixing outer tube front view;

Fig. 5 is the utility model mixing outer tube left view;

Fig. 6 is the utility model mixture gas nozzle front view;

Fig. 7 is the utility model mixture gas nozzle left view.

The utility model is described in further detail below in conjunction with accompanying drawing for detailed description of the invention.

As can be seen from Fig. 1 to Fig. 7, coal-turned-gas boiler coal gas mixing tube, be made up of pipe 1, mixing outer tube 2 and mixture gas nozzle 3 in mixing, mixing outer tube 2 is enclosed within the interior pipe 1 of mixing, in mixing, pipe 1 forms air between outer tube 2 and press from both sides chamber 5 with mix, and interior pipe 1 side of mixing arranges gas entry 6, mixes outer tube 2 side and is fixedly connected with mixture gas nozzle 3, mixing outer tube 2 arranges air introducing port 7, in mixing, pipe 1 is arranged and rotatingly penetrate sucker 4.

The injecting tube of pipe 1 to be internal diameter be gradually closing in mixing.

Described air introducing port 7 becomes 60 degree of angles with mixing outer tube 2 axis.

Principle of the present utility model is that in mixing, coal gas will to be penetrated from gas entry and is drawn onto mixture gas nozzle by pipe, and in mixing, the air from mixing outer tube to be penetrated with the attitude rotated from air folder chamber be drawn onto mixture gas nozzle by rotating sucker of penetrating by pipe.
