Abstract
The utility model belongs to the field of exhaust silencers, and particularly relates to a silencer for steam exhaust. The silencer for the steam exhaust comprises a silencer barrel body, a connecting portion used for being connected with other devices is arranged on the outer wall face of the silencer barrel body, and a steam inlet is formed at the lower end of the silencer barrel body. The silencer for the steam exhaust is characterized in that multiple layers of choke blocks are arranged inside the silencer barrel body, a plurality of flow restriction orifices are formed in the choke blocks, and a plurality of small exhaust holes are evenly formed in the top portion of the silencer barrel body. According to the silencer for the steam exhaust, the throttling depressurization principle and the small hole jet principle are combined, a good silencing effect is achieved, requirements of various using environments are met, and meanwhile, the silencer for the steam exhaust is reasonable in structure and small in size, thereby meeting the size requirements of various using conditions, and the silencer for the steam exhaust is light in weight and convenient to mount, labor intensity of mounting workers is lowered, and mounting time is shortened.
Description
Technical field
The utility model belongs to the exhaust silencer field, particularly a kind of silencer for the discharge of steam noise elimination.
Background technology
Silencer is to stop sound transmission and a kind of device of allowing air-flow to pass through, is the important measures of eliminating air power noise.Silencer is mounted in the low noise device that falls on the gas channel of air force equipment (such as air blast, air compressor machine) or in the inlet and exhaust system.Silencer can stop the propagation of sound wave, allows air-flow to pass through, and is the effective tool of control noise.At present, the discharge of steam of boiler plant directly discharges in atmosphere, and sound is larger in the time of discharging, on around the certain impact that produces of people's live and work.
Summary of the invention
For the deficiencies in the prior art, the utility model has designed a kind of steam discharge muffler that adopts reducing pressure by regulating flow and micropore jet theory to combine, sound deadening capacity of the present utility model is large, discharging after the noise elimination can be satisfied the requirement of environment, the utility model is rational in infrastructure simultaneously, volume is little, and is lightweight, easy for installation.
The utility model is achieved through the following technical solutions:
Steam discharge muffler, it comprises silencer cylinder, be provided with the connecting portion that is connected with other devices on the outside wall surface of silencer cylinder, the lower end of described silencer cylinder is provided with air inlet, it is characterized in that: the inside of described silencer cylinder is provided with the multilayer choke block, be provided with a plurality of throttle orifices on the described choke block, silencer cylinder top uniform is provided with a plurality of exhaust holes.
The aperture of the throttle orifice on the described choke block increases from the bottom up successively, and the aperture of throttle orifice increases successively, has improved the effect of the reducing pressure by regulating flow of choke block.
In sum, the utility model has used the principle of reducing pressure by regulating flow and micropore jet to combine, has preferably soundproof effect, satisfy the environmental requirement of various environments for use, the utility model is rational in infrastructure simultaneously, the little volume requirement that satisfies various use occasions of volume, and the utility model lighter weight, be convenient to install, reduced installer's labour intensity, also shortened the set-up time.
Description of drawings
Fig. 1 is structural representation of the present utility model;
1 is exhaust hole among the figure, and 2 is air inlet, and 3 is choke block, and 4 is silencer cylinder, and 5 is connecting portion.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Steam discharge muffler as shown in Figure 1, it comprises silencer cylinder 4, be provided with the connecting portion 5 that is connected with other devices on the outside wall surface of silencer cylinder 4, the lower end of described silencer cylinder 4 is provided with air inlet 2, it is characterized in that: the inside of described silencer cylinder 4 is provided with multilayer choke block 3, be provided with a plurality of throttle orifices on the described choke block 3, silencer cylinder 4 tops uniform is provided with a plurality of exhaust holes 1.
The aperture of the throttle orifice on the described choke block 3 increases from the bottom up successively, and the aperture of throttle orifice increases successively, has improved the effect of the reducing pressure by regulating flow of choke block.
In sum, the utility model has used the principle of reducing pressure by regulating flow and micropore jet to combine, has preferably soundproof effect, satisfy the environmental requirement of various environments for use, the utility model is rational in infrastructure simultaneously, the little volume requirement that satisfies various use occasions of volume, and the utility model lighter weight, be convenient to install, reduced installer's labour intensity, also shortened the set-up time.
