Description
Technical field
The present invention relates to a kind of atomising device, be specifically related to a kind of oxygen-eliminating device atomising device.
Background technology
In boiler feedwater treatment process process, deoxygenation is a very crucial link.Oxygen-eliminating device is auxiliary equipment important in Turbo-generator Set heat regenerative system, and atomising device is the vitals of oxygen-eliminating device, it is for by condensed water or supplementing water atomization, atomising device directly affects the deaerating effect of oxygen-eliminating device, the atomising device of oxygen-eliminating device should have suitable version, under suitable flow and pressure reduction, make the atomizing effect of atomising device good.The atomising device of current rotating film type thermal deaerator, can not carry out rotary-atomizing well to the current of the condensed water passing through or supplementing water, thereby can not effectively reduce evaporated water in oxygen-eliminating device, and atomizing effect is undesirable.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of to the water flow rotary atomization of passing through, oxygen-eliminating device atomising device that atomizing effect is good.
In order to solve the problems of the technologies described above, the invention provides a kind of oxygen-eliminating device atomising device, comprise housing and coordinate cylindrical adapter sleeve with housing, adapter sleeve is provided with inner via hole, in housing, be provided with spray orifice, in the inner via hole of adapter sleeve, cylinder shape valve is housed, on the outer surface of cylinder shape valve, having 6 ~ 8 is axially the thread groove of spill.
Adopt the oxygen-eliminating device atomising device tool of technique scheme to have the following advantages: 6 ~ 8 that on the outer surface of the cylinder shape valve in adapter sleeve inner via hole, offer is axially the thread groove of spill, make the thread groove of spill and the inner via hole of adapter sleeve of the outer surface of cylinder shape valve radially have certain interval, when have the water of certain pressure and flow velocity to flow to arrange on cylinder valve external surface spill thread groove time, water impact cell wall produces certain peripheral force, cylinder shape valve is subject to peripheral force and does the used time and can relatively rotate, the water flow energy of the condensed water passing through or supplementing water is carried out to rotary-atomizing well, thereby effectively reduce evaporated water in oxygen-eliminating device, atomizing effect is good.
As preferred version, in order to be conducive to the rotary-atomizing of current, the spiral angle of described thread groove is 15 °.
As preferred version, in order effectively the current that pass through to be rotated to atomization, described spray orifice is formed by connecting by connecting hole by two conical spray orifices, and spray orifice is dumbbell shape.
Accompanying drawing explanation
Fig. 1 is the cutaway view of oxygen-eliminating device atomising device of the present invention;
In figure: 1-housing, 2-sealing ring, 3-spray orifice, 4-cylinder shape valve, 5-adapter sleeve, 6-thread groove.
the specific embodiment
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
As shown in Figure 1, the invention provides a kind of oxygen-eliminating device atomising device, comprise housing 1 and coordinate cylindrical adapter sleeve 5 with housing 1, adapter sleeve 5 is provided with inner via hole, housing 1 inside is provided with spray orifice 3, cylinder shape valve 4 is housed in the inner via hole of adapter sleeve 5, on the outer surface of cylinder shape valve 4, having 8 is axially the thread groove 6 of spill, the spiral angle of thread groove 6 is 15 °, spray orifice 3 is by a left side, right two conical spray orifices are formed by connecting by company hole, spray orifice 3 is dumbbell shape, connecting hole connects left, the aperture of right two conical spray orifices, spray orifice 3 is done as a whole being located in housing 1, if the housing of internal thread 1 screws with the left end that is provided with externally threaded adapter sleeve 5, cylinder shape valve 4 is limited to the appropriate location in adapter sleeve 5 inner via holes, adapter sleeve 5 right-hand members are threaded fixing with water supply installation employing, the inner via hole of adapter sleeve 5 is as the passage of current right-to-left, 8 that on the outer surface of cylinder shape valve 4, arrange is being axially the thread groove 6 of spill, make cylinder shape valve 4 appearances and adapter sleeve 5 inner via holes radially gapped, being subject to peripheral force does the used time and can relatively rotate, the periphery coordinating with adapter sleeve 5 at housing 1 is also processed with sealed groove, sealing ring 2 is housed in sealed groove, in order effectively to prevent leaking between periphery that current coordinate with adapter sleeve 5 from housing 1, sealing ring 2 is O type rubber seal, adapter sleeve 5 right-hand member structures are external pipe thread, be connected with the Internal Pipe Thread of supply channel.In concrete enforcement, in order to be conducive to water flow rotary atomization, the number of thread groove 6 also can be chosen as arbitrary value in 6 ~ 8 according to actual conditions.
Operation principle of the present invention: flow into from adapter sleeve 5 right-hand members when supplying water, after cylinder shape valve 4 is rotated, current advance under the drive of cylinder shape valve 4, simultaneously affix rotatablely move, enter the right conical spray orifice of spray orifice 3, because conical spray orifice circulation area diminishes gradually, rate of flow of fluid under certain flow improves, dynamic pressure increases, static pressure reduces, while reaching the aperture place of conical spray orifice, dynamic pressure reaches maximum, static pressure reaches minimum of a value, the left end external ambient atmosphere pressure of spray orifice 3 is greater than the aperture place static pressure of conical spray orifice, air flows to aperture place, the current mixed aerosol flowing out at a high speed with aperture, the conical spray orifice ejection of left end from spray orifice 3, form rotary-atomizing current, and then atomization flow fully contacts with the heating steam in oxygen-eliminating device, instantaneous water is heated to saturation temperature, effectively reduce evaporated water in oxygen-eliminating device simultaneously, the on-condensible gas of the overwhelming majority is separated out rapidly, atomizing effect is good.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the premise without departing from the principles of the invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
