Abstract
The utility model relates to a new pressure-reducing exhaust noise silencer. The silencer with no top plate is a cylinder composed of a cylindrical casing and a lower bottom plate, wherein, the lower bottom plate is welded with a steam inlet pipe and a drainage outlet pipe; an inner cylinder body with resistance micro-hole plates is arranged in the cylindrical casing; an umbrella-shaped perforated plate below which an exicrcle and a cylinder body casing are welded is arranged below the inner cylinder body; a plurality of annular decompression chambers welded by multilayer baffle plates are arranged above the lower bottom plate; the top part of each decompression chamber is sealed by using steel plates to cause each decompression chamber to be independent. The baffle plates among the decompression chambers are drilled with a plurality of orifices in a tangential direction; the directions of the orifices of the tangential direction of the adjacent two baffle plates are opposite. Because vapor can be implemented with resistance silencing after step-by-step depressurization, noise reducing effect is obvious.
Description
The utility model relates to a kind of silencing apparatus, is a kind of steam step-down steam discharge silencing apparatus.
Steam steam discharge silencing apparatus generally adopts micropore or macropore silencing apparatus at present; these silencing apparatuss generally can only reduce about 30 decibels of noises; but along with improving constantly of boiler parameter; exhaust noise also improves gradually; the noise that has has increased to 150 decibels; if adopt the silencing apparatus of micropore or macroporous structure, can not reach requirement on environmental protection.
The purpose of this utility model provides a kind of steam step-down steam discharge silencing apparatus, it is that product according to the volume of gas and pressure is this basic principle of constant, make steam segmentation in discharge process enlarge volume and reduce pressure, steam is under low pressure discharged through the micro silencer passage, reaches the noise elimination purpose.
The purpose of this utility model is achieved in that steam step-down steam discharge silencing apparatus, the cylinder that it is made up of cylindrical housing and lower shoe, no upper plate, on lower shoe, be welded with steam inlet pipe and drain pipe, resistance microwell plate inner barrel is housed in cylindrical housing, it below the inner barrel umbrella shape porous slab, cylindrical and cylinder shell welding under the umbrella shape porous slab, it above the lower shoe a plurality of annular decompression chamber that multilayer insulating panel is welded into, the top of each decompression chamber seals with steel plate, make each decompression chamber independent, bore a plurality of tangential throttle orifices on the dividing plate between each decompression chamber, the tangential throttle orifice direction of adjacent two dividing plates is opposite.The steam that flows out after the multistage throttle step-down is eliminated the noise, continues to reach the noise elimination purpose by entering atmosphere after the noise elimination of resistance microwell plate.
This steam step-down steam discharge silencing apparatus and since adopt multistage decompression chamber steam step-by-step step-down noise elimination after the umbrella shape porous slab enters inner barrel, continue to eliminate the noise by the resistance microwell plate, exhaust noise drops to below 80 decibels.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is embodiment's sectional drawing of model utility.
Fig. 2 is I-I sectional drawing of Fig. 1.
Fig. 3 is the II portion enlarged view of Fig. 2.
Among the figure 1, cylinder shell 2, microwell plate inner barrel 3, umbrella shape porous slab 4, top steel plate 5, toroidal membrane 6, lower shoe 7, decompression chamber 8, steam inlet pipe 9, hydrophobic outer pipe 10, tangential throttle orifice
In Fig. 1, cylinder shell (1) is formed closed cylinder down with lower shoe (6), be welded with steam inlet pipe (8) and hydrophobic outer pipe (9) on the lower shoe, microwell plate inner barrel (2) is housed in cylinder shell, be umbrella shape porous slab (3) below the inner barrel, the umbrella shape porous slab is circle and cylinder shell (1) welding down, top steel plate (4) sealing of the top of decompression chamber (7), go up brill a plurality of tangential throttle orifices (10) at toroidal membrane (5), the tangential throttle orifice direction of adjacent two dividing plates is opposite.
The flow direction of steam is shown in arrow among Fig. 1, and steam enters from steam inlet pipe (8), step by step after the step-down throttling, enters microwell plate inner barrel (2) through umbrella shape porous slab (3) through decompression chamber (7), and steam enters atmosphere after eliminating the noise.
The shape of decompression chamber embodiment illustrated in fig. 2 and steam are illustrated by the flow direction after throttle orifice (10) step-down in decompression chamber.
The arranged tangential orientation of throttle orifice (10) on toroidal membrane (5), II shown in Figure 3 portion amplification back.
Claims (2)
1, a kind of steam step-down steam discharge silencing apparatus, it is characterized in that: the cylinder of forming by cylindrical housing and lower shoe, no upper plate, on lower shoe, be welded with steam inlet pipe and hydrophobic outer pipe, the inner barrel that the resistance microwell plate is formed is housed in cylindrical housing, it below the inner barrel umbrella shape porous slab, cylindrical and cylinder shell join under the umbrella shape porous slab, it below the lower shoe a plurality of annular decompression chamber that multilayer insulating panel is welded into, the top of each decompression chamber seals with steel plate, makes between each decompression chamber to separate and independence with dividing plate.
2, steam step-down steam discharge silencing apparatus according to claim 1 is characterized in that: bore a plurality of tangential throttle orifices on the dividing plate between each decompression chamber, the tangential throttle orifice direction of adjacent two dividing plates is opposite.
