Abstract
The utility model provides a frequency regulation and revolving type pulsation generator. The rotary speed of an electrical motor is controlled by regulating the value of voltage by a frequency regulation controller, so the rotary speed of a rotary valve which is connected with the electrical motor is controlled. The frequency regulation and pulsation of air current can be realized by switching on or switching off the rotary valve. The utility model is characterized in that valve sheets are symmetrically arranged on both sides of a central shaft of the rotary valve which is connected with an electrical motor shaft, and transverse reinforcement bars are fixed on the valve sheets.
Description
The utility model relates to the rotary flutter generator of a kind of novel frequency-adjustable, and it belongs to the improvement to existing flutter generator, is used to realize gas-solid or gas-liquid pulsation transmission or pulsation reaction.
Pulsation is transmitted or the pulsation reaction is a special kind of skill of rising in recent years, and it is compared with stable state transmission or reaction technology, has very high transmission rate or reactive rate, has strengthened mass transfer, heat transfer and reaction greatly.At present, pulse technology has been applied to industrial combustion process, and it is compared with the routine burning, and combustion efficiency can be up to more than 95%, and combustion intensity improves more than 60 times, and the coefficient of heat transfer improves 7 times, and the discharge amount of pollutants such as oxynitrides reduces greatly.Sichuan University is applied to fluidization with pulsation and has also obtained remarkable result.Realize that the pulsation of gas-solid or gas-liquid is transmitted or the key of reaction is a flutter generator, promptly want the transmission rate or the reactive rate that reach desirable, the flutter generator that must have frequency, intensity and an equipment to be complementary.At present, the flutter generator that is mainly used in industrial combustion process has mechanical type one-way valve and pneumatic type one-way valve.The mechanical type one-way valve has diaphragm type, reed-type and rotary etc., and it is simple in structure, low cost of manufacture, but design difficulty is bigger, is difficult for guaranteeing the self-absorption function of burner; The operating cost of pneumatic type one-way valve is lower, but mainly be to realize by the rational design and installation of device interior, design difficulty is bigger, therefore, the design of flutter generator has become the key of Application and Development pulsating Combustion Technology, also is a great problem of applying pulse technology in other industrial process.
The purpose of this utility model is to avoid fast the deficiencies in the prior art part, provides a kind of novel frequency-adjustable rotary flutter generator.
The purpose of this utility model is to realize like this, it mainly is made of frequency modulation control device, motor, rotary valve etc., come the rotating speed of regulating voltage control motor by the frequency modulation control device, thereby adjust the rotating speed of the rotary valve that is connected with motor, utilize its break-make to realize the pulsation of air-flow frequency-adjustable.Its structure be motor with rotary valve shaft to being connected, rotary valve plate is along axisymmetric, running shaft is supported by bearing support, bearing, rotary valve shell, valve block is along the central shaft symmetry, horizontal stiffening rib is installed on valve block, stretch out the central shaft of rotary valve shell and the output shaft of motor and be connected on the same axis by shaft coupling, the frequency modulation control device is connected with motor by electric wire.
Flutter generator provided by the utility model, because the valve block of rotary valve is along the central shaft symmetry, forward and reverse force balance, it is little to rotate required moment, and energy consumption is low; Realize frequency modulation by the frequency modulator variable voltage control, be easy to realize and the pulsation of system matches that its tuning range is wide, and is simple and feasible; Utilize rotary valve to realize pulsation, little to former steady-state system change, only need on airflow pipeline, to install electronic rotary valve and can realize pulsation transmission or pulsation reaction.
Describe the concrete structure of the rotary flutter generator of foundation frequency-adjustable provided by the utility model in detail below in conjunction with drawings and Examples.
Accompanying drawing is the structural representation according to the rotary flutter generator of frequency-adjustable provided by the utility model.
Among the figure, 1 is the frequency modulation control device, and 2 is motor, and 3 is the rotary valve shell, and 4 is valve block, and 5 is the valve block stiffening rib, and 6 is central shaft.
The concrete structure of rotary valve is the valve block 4 that is symmetrically arranged at central shaft 6, stiffening rib 5 is housed on the valve block 4, rotary valve shell 3 center lines and central shaft 6 are on same axis, by bearing, bearing support central shaft 6 and rotary valve shell 3 are linked together, stretch out the central shaft of rotary valve shell 3 and the output shaft of motor 2 and link together, realize that motor and rotary valve rotate synchronously with shaft coupling.Frequency modulation control device 1 is electrically connected with motor 2.In the present embodiment, frequency modulation control device 1 is made up of one 1.5 kilowatts voltage stabilizer and 1.5 kilowatts transformer, it is that 1000 watts motor is communicated with 700 millimeters of the diameters of rotary valve shell 3, central shaft diameter 30mm with electric wire with rated power, two semicircle valve blocks 4 are installed in the both sides of central shaft 6, symmetric arrangement, valve block edge and outer casing inner wall be the 3mm space at interval, adopts three horizontal stiffening ribs, increase the intensity of valve block 4, above-mentioned flutter generator is installed on the pipeline that diameter is 700mm.
At industrial use flutter generator described in the utility model, can realize following advantage: (1) rotation Moment is little, and energy consumption is low; (2) be easy to realize and the pulsation of system matches that tuning range is wide; (3) after the voltage stabilizing Pressure regulation has guaranteed that the pulsation period is steady; (4) realize gas with the rotary valve switch, its ripple amplitude up to More than 95%, fluctuation intensity is big; (5) change little to former steady-state system equipment; (6) remote controlled and Operation; (7) applied widely, simple in structure, be easy to make, it is convenient to install, overhaul.
