Abstract
The utility model discloses a self-adaptive apparatus for gas flow, which is used for regulation of flow in industry and comprises a spring and a resistance force element which are sheathed on a threaded rod. The resistance force element is connected with a regulating baffle plate through a regulating connecting rod, and the utility model can automatically regulate the matching of the flow according to the proportional relation between the size of the resistance force element and the gas velocity. The utility model has the advantages of simple structure, practicality and low cost.
Description
The utility model relates to a kind of gas flow adaptive device, and particularly a kind of gas flow is from adaptive device.
At present, the commercial unit ubiquity relevant with aerodynamic force the unmatched problem of flow, for example, cross air dispatching adopts the method that changes sectional dimension to reach the uniform purpose of air distribution under the Industrial Boiler fire grate, still, the resistance in coal seam is inhomogeneous on the fire grate, make that the air distribution of whole combustion system is unmatched, " negative and positive stove " or " burner " can occur, have a strong impact on boiler and normally move, boiler output is descended, and efficient reduces.For station boiler, Air Hood Rotating Type Air Preheater especially, the flow of air and flue gas does not match in the heat transfer element, makes that regional area heat transfer element wall temperature is lower, is easy to generate problems such as cold end corrosion and stifled ash, therefore influences boiler output, wastes energy.
The purpose of this utility model is intended to solve the industrial gas flow adaptive problem on certain cross section that needs, and proposes a kind ofly can have characteristics simple in structure, practical, that cost is low according to the device of the automatic adjustments of gas flow of gas velocity.
The utility model is resistance size and the proportional relation of gas velocity according to resistance element, is suitable for adaptive principle, reaches the purpose of flow matches.
The utility model comprises that one is enclosed within spring, the resistance element on the screw rod, and resistance element is connected with controllable register by regulating connecting rod.
When gas velocity was very big, resistance element was stressed big, and the drag effect of resistance element is compressed spring on spring, and the connecting rod by linking to each other with resistance element, the aperture of baffle plate is reduced, thereby gas flow is reduced; Otherwise, the aperture of baffle plate is increased, gas flow increases.When being certain determined value, amassing of gas velocity and sectional area (determine) that the resistance of resistance element and the acting force of spring are in equilibrium state, thereby reach the adaptive purpose of flow according to designing requirement.In case this balance is subjected to external disturbance, new balance will rebulid.
This shows that the utility model is a kind of adaptive aut.eq. of flow of in good time, suitablely regulating.
The utility model is applied to Industrial Boiler, can be so that whole combustion system be complementary along fire grate width air distribution and coal seam resistance, elimination " negative and positive stove " or " burner " etc. has a strong impact on boiler and normally moves, and makes boiler combustion steady, efficient improves, thereby reaches purpose of energy saving.
For the fan housing of station boiler or revolution air preheater, make flue gas, air velocity proper fit in heat transfer element, eliminate the cold end corrosion and the stifled ash of low temperature heating surface, improve boiler operating efficiency, improve boiler output, energy savings.
Accompanying drawing is a structure principle chart of the present utility model.
Below in conjunction with accompanying drawing structural principle of the present utility model and principle of work are done detailed explanation.
The utility model comprises that one is fixed on the screw rod (8) on the framework (6), and two controllable registers (2) that are connected with framework (6) skeining network; Be with spring (3) and resistance element (1) on the screw rod (8); One end of spring (3) withstands resistance element, and the other end withstands setting nut (5), and two controllable registers (2) are regulated connecting rod (4) by one respectively and are connected with resistance element (1).
When gas velocity was very big, resistance element (1) was stressed, and the drag effect of resistance element (1) is on spring (3), spring (3) is compressed, and the adjusting connecting rod (4) by linking to each other with resistance element (1), the aperture of controllable register (2) is reduced, thereby gas flow is reduced; Otherwise, the aperture of controllable register (2) is increased, gas flow increases.
In addition, (7) are the coarse adjustment pins among the figure.
Claims (2)
1, gas flow is characterized in that from adaptive device, comprises that one is enclosed within spring (3), the resistance element (1) on the screw rod (8), and resistance element (1) is connected with controllable register (2) by regulating connecting rod (4).
2, gas flow according to claim 1 is from adaptive device, it is characterized in that, said screw rod (8) is fixed on the framework (6), be with spring (3) and resistance element (1) on the screw rod (8), one end of spring (3) withstands resistance element (1), the other end withstands setting nut (5), resistance element (1) is regulated connecting rod (4) by two and is connected with an end of two controllable registers (2) respectively, and the other end of two controllable registers (2) twists network respectively and is connected on the framework (6).
