Abstract
The utility model relates to a mixed heater for water and steam without noise, which is composed of a housing (1) and a spraying pipe (2) which is positioned in the housing (1), wherein spraying holes (4) are evenly distributed on the spraying pipe (2). The diameter of each of the spraying holes (4) is between 3 and 5 millimeters, and the separation distance of the spraying holes (4) is larger than 6 millimeters. The diameter of a throat opening (3) of the spraying pipe (2) is determined according to rated water flow and the velocity of the throat opening of the spraying pipe. The relation of mutual restriction of the pressure of circulating water and steam of the utility model can not exist when the circulating water and the steam are operated so that the utility model can be normally operated under the pressure of the steam at 0.05 mpa. The utility model is suitable for units with low pressure of a boiler, the use range of the mixed heater for water and steam is widened, and new way is invented for saving energy. A system can normally supply heat when the pressure of the steam is largely fluctuated and any regulation is not done so that the utility model has the advantages of no noise, stable operating condition and simple operation.
Description
Technical field
The utility model relates to a kind of noiselessness steam-water injection.
Background technology
When carbonated drink is mixed, need higher steam pressure, promptly steam pressure must could be compressed into mixing chamber to steam more than 0.4MPa～0.7MPa.The pressure of steam supply of general industry boiler will reach relatively difficulty of the above requirement of 0.4MPa～0.7MPa, and particularly old boiler and industrial waste steam boiler can't reach at all.Be difficult to use energy-efficient steam-water injection as heat transmission equipment, limited the scope of application of steam-water injection.Owing to do not reach the stable pressure of steam supply of 0.4MPa～0.7MPa, cause steam-water injection to be in operation because steam pressure frequent fluctuation fluctuated produces stream, vibration and noise between steam and water bursting, carbonated drink, system can't normally be moved.Noise can reach 100dB (A)～more than the 150dB (A), surpasses codes and standards≤80dB (A).The severe contamination that environment has been caused.
Summary of the invention
The technical problem that the utility model solves: design a kind of noiselessness steam-water injection, the pressure of recirculated water and the pressure of steam do not have the relation of mutual restriction when operation, and steam pressure just can normally move when 0.05MPa.Be adapted to the low unit of boiler pressure and use, widened the scope of application of steam-water injection, be the energy-conservation new way of having created.And need not do any levelling when steam pressure fluctuation is big, system is normal heat supply running still, noiselessness.Operating mode is stable, and is simple to operate.
Technical solution of the present utility model:
Design philosophy: the caliber size series of former jet pipe aditus laryngis has been carried out comprehensive check design, reduced the drag losses of jet pipe aditus laryngis under specified discharge, carried out new jet pipe aditus laryngis caliber series.Comprehensive check design has been carried out in the aperture of former jet pipe spray orifice, reduced the drag losses of jet pipe spray orifice under specified discharge, carried out new jet pipe spray orifice aperture series.Flow velocity to former jet pipe aditus laryngis and jet pipe spray orifice has carried out design, check, has carried out new jet pipe flow velocity series.
Organization plan: the noiselessness steam-water injection is made of housing (1) and the jet pipe (2) that is positioned at housing (1), and jet pipe (2) is gone up uniform spray orifice (4), and the diameter of the aditus laryngis (3) of jet pipe (2) is determined according to following computing formula:
Wherein, D---jet pipe throat diameter (millimeter), the specified discharge of G---(ton/time), V---jet pipe aditus laryngis flow velocity (meter per second), and must guarantee that jet pipe aditus laryngis flow velocity is 10～20 meter per seconds.
The diameter of spray orifice (4) is 3～5 millimeters of φ, and spacing＞6 of spray orifice (4) millimeter.Filler between housing (1) and the jet pipe (2) is a Bu Rust steel steel cuttings (5).
The utility model compared with prior art has the following advantages and effect:
(1) the utility model has thoroughly changed traditional vapour-water mixing exchanged form, and in carbonated drink mixed process, therefore the relation that steam pressure and circulating water pressure do not condition each other steams condition pressure when 0.05Mpa, and system just can normally move.Steam pressure greater than 0.05Mpa (when maximum pressure 0.6～1.0MPa) is above, the heating operation better effects if, faster, more save.Be adapted to the low unit of boiler pressure and use, widened the scope of application of steam-water injection.
(2) the utility model is in carbonated drink mixed process, no matter the pressure of steam is height or low, steam-water injection all can mix by normal steam supply, the problem of stream, vibration, noise has all obtained solution between steam and water bursting, carbonated drink, through the actual measurement to the steam-water injection operating condition, noise is≤65dB (A).
(3) the utility model can be used saturated vapor (maximum pressure≤1.0Mpa selecting for use of thermal source, maximum temperature≤180 ℃), also can use superheated steam (pressure≤0.3Mpa, overtemperature≤260 ℃), and it is fine to use superheated steam to carry out the heating operation effect.Further widened the scope of application of steam-water injection.
(4) the utility model and shell and tube carbonated drink interchanger compare, 30-50% capable of saving fuel; Saving steel more than 80%, save erection space more than 70%, is the ideal product that substitutes the indirect type heat exchanger.
