Abstract
A continuous and accurate low-pressure gas mixing device is characterized in that a gas inlet pipe and a mixture gas outlet pipe are arranged on a tank body; a gas inlet nozzle is arranged on the gas inlet pipe; a support frame is connected and fixed with the inner wall of the tank body; a shaft hub is connected and fixed with the support frame; bearings are arranged in the shaft hub; a fan blade rotating shaft penetrates through the inner circles of the bearings; the fan blade rotating shaft and the bearings are limited through circlips for shafts; and one end of the fan blade rotating shaft is connected and fixed with a stirring fan blade, and the other end thereof is connected and fixed with another stirring fan blade. The utility model completely solves the problem of the prior low-pressure continuous fuel gas distribution system that the gas distribution accuracy is too low, and greatly improves the gas distribution accuracy of the gas distribution system; the partial difference between the practical Wobbe index and the theoretic Wobbe index is less than or equal to 0.5 percent; and the gas distribution accuracy is 4 times higher than the national standard; therefore, the volume of the integrated gas distribution system is decreased, and the manufacture cost is lowered.
Description
Technical field:
The utility model relates to a kind of unstripped gas with two or more and evenly mixes by different proportion, supplies with the continuously accurate gas mixing device of low pressure of the production and the experiment of gas appliance.
Background technology:
Gas mixing device in the at present domestic continuous air distribution system of combustion gas low pressure, owing to be the combustion gas distribution, unstripped gas is a fuel gas, inconvenience uses motor to stir, the mixed gas of gas mixing device is by the mixed naturally gas of the power of unstripped gas self, cause the air distribution system precision not up to standard, the reality that can not satisfy the national standard requirement is joined the quality of fit of combustion gas Wobbe index and theoretical Wobbe index deviation≤± 2%, and the air distribution system that has does not also reach the national standard requirement far away.
Summary of the invention:
The purpose of this utility model provides the continuously accurate gas mixing device of a kind of low pressure, and it has thoroughly solved the low excessively difficult problem of distribution precision of present combustion gas air distribution system, and the distribution precision of air distribution system is significantly promoted.
The continuously accurate gas mixing device of a kind of low pressure, it comprises can body, described can body is provided with air inlet pipe and gaseous mixture escape pipe, and air inlet pipe is provided with nozzle of air supply, and bracing frame and can body inwall are connected and fixed, propeller boss and bracing frame are connected and fixed, be provided with bearing in the propeller boss, circle in the bearing is passed in the flabellum rotating shaft, and flabellum rotating shaft and bearing are spacing by circlip for shaft, one end of flabellum rotating shaft is connected and fixed with stirring flabellum, and the other end of flabellum rotating shaft is connected and fixed with the stirring flabellum.
The beneficial effects of the utility model, described can body is provided with air inlet pipe and gaseous mixture escape pipe, air inlet pipe is provided with nozzle of air supply, bracing frame and can body inwall are connected and fixed, propeller boss and bracing frame are connected and fixed, be provided with bearing in the propeller boss, circle in the bearing is passed in the flabellum rotating shaft, flabellum rotating shaft and bearing are spacing by circlip for shaft, one end of flabellum rotating shaft is connected and fixed with the stirring flabellum, the other end of flabellum rotating shaft is connected and fixed with stirring flabellum, and it has thoroughly solved the low excessively difficult problem of the continuous distribution precision of present combustion gas low pressure, and the distribution precision of air distribution system is significantly promoted; Join combustion gas Wobbe index and theoretical Wobbe index deviation≤± 0.5% in fact, the distribution precision is higher than 4 times of national standards; The air distributing device volume of integrating is little, has reduced manufacturing cost.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1: be structural representation of the present utility model;
Fig. 2: be the A-A cutaway view;
Fig. 3: be the B-B cutaway view.
The specific embodiment:
As Figure 1-3, the continuously accurate gas mixing device of a kind of low pressure, can body 5 is provided with air inlet pipe 1, air inlet pipe 12, air inlet pipe 13, air inlet pipe 14 and gaseous mixture escape pipe 6, air inlet pipe 1, air inlet pipe 12, all be provided with nozzle of air supply 2 on air inlet pipe 13 and the air inlet pipe 14, bracing frame 4 is connected and fixed with can body 5 inwalls, propeller boss 10 is connected and fixed with bracing frame 4, be provided with bearing 9 and bearing 11 in the propeller boss 10, circle and bearing 11 interior circles in the bearing 9 are passed in flabellum rotating shaft 7, flabellum rotating shaft 7, bearing 9 and bearing 11 are spacing by circlip for shaft 16 and circlip for shaft 15 respectively, one end of flabellum rotating shaft 7 is connected and fixed with stirring flabellum 3, the other end of flabellum rotating shaft 7 is connected and fixed with stirring flabellum 8, nozzle of air supply 2 becomes vertical 90 ° with the blade face of stirring flabellum 3, and the unstripped gas of coming in is directly injected on the blade face of stirring flabellum 3; In the time of work, the unstripped gas of different densities enters the utility model by nozzle of air supply 2, charge air flow is directly injected on the blade face of stirring flabellum 3 by nozzle of air supply 2, stir flabellum 3 fast rotational, promote to stir flabellum 6 rotations simultaneously, thereby realized that the unstripped gas that stirs different densities in the utility model evenly mixes output, really realized the continuously accurate distribution air feed of low pressure of combustion gas air distribution system.
Decide in the kind of the nozzle of air supply quantity described in the utility model according to unstripped gas.
