Description
Technical field
The utility model relates to the vacuum pump application field, is specifically related to a kind of wet vacuum pump exhaust silencer.
Background technique
The wet type Roots pump needs during work to inject sealing water at suction port, and sealing water has reduced rotor and gap between rotor in the up one-tenth water membrane of rotor, thereby improves the efficient of vacuum pump.Because sealing water directly contacts with rotor, water quality is just had requirement, the soft water that fitness for purpose was handled.The wet type Roots pump is in exhausting air, can produce very big noise, therefore must install silencing apparatus additional at the relief opening of wet type Roots pump, because the wet type Roots pump is in exhausting air, sealing water and gas mix, and in the existing equipment, a part is only considered noise reduction, directly discharging causes very big waste.Another part equipment has carried out separating recovery to aqueous vapor, and relief opening has been done simple noise reduction and handled, but drain opening is still gas-entrained, produces very big noise, and is difficult for handling, and noise still exceeds standard.
The model utility content
For addressing the above problem, the purpose of this utility model is to provide a kind of aqueous vapor that has both simultaneously to separate and reclaim and noise meets the wet vacuum pump exhaust silencer of NBS.
For achieving the above object, the technical solution of the utility model is: a kind of wet vacuum pump exhaust silencer, comprise moisture separator and silencer, described moisture separator is provided with suction port, separating opening and drain opening, described silencer is provided with inlet and relief opening, the inlet of described silencer is connected with the separating opening of described moisture separator, described silencer comprises the silencer shell, be located at the porous slab in the silencer shell and place sound absorbing material between described porous slab and the shell, and described inlet and relief opening are equipped with porous slab.
Preferably, also comprise aqua storage tank, described aqua storage tank is connected with described drain opening.
Preferably, also comprise condensate water recovery device, the inlet that described condensate water recovery device is provided with is connected with the relief opening of described silencer, and the water dropping openings that described condensate water recovery device is provided with is positioned at the top of described aqua storage tank or is connected by water pipe.
Preferably, described moisture separator is provided with a cylindrical spherical or conical cavity, and described suction port tangentially is communicated in described cylindrical spherical or conical cavity.
Preferably, described aqua storage tank is provided with flow-off, and the level height of described flow-off is higher than the level height of described drain opening.
Adopt the beneficial effect of the technical program to be: to adopt moisture separator and silencer to carry out aqueous vapor and separate the recovery and the processing of eliminating the noise, both reclaimed sealing water and saved resource, make the noise reduction again and meet NBS.

Numeral and the represented corresponding part title of letter among the figure:
1. moisture separator 11. suction ports 12. drain opening 13. separating openings 2. silencer 21. porous slabs 22. sound-absorbing materials 3. aqua storage tanks 31. flow-offs 4. condensate water recovery devices
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Embodiment 1,
As depicted in figs. 1 and 2, a kind of wet vacuum pump exhaust silencer, comprise moisture separator 1 and silencer 2, moisture separator 1 is provided with suction port 11, separating opening 13 and drain opening 12, silencer 2 is provided with inlet and relief opening, the inlet of silencer 2 is connected with the separating opening 13 of moisture separator 1, silencer 2 comprises the silencer shell, be located at the porous slab 21 in the silencer shell and place sound absorbing material 22 between porous slab 21 and the shell, and inlet and relief opening are equipped with porous slab 21.
Moisture separator 1 is provided with a circular cylindrical cavity, and suction port 11 tangentially is communicated in circular cylindrical cavity.
Also be provided with aqua storage tank 3 in moisture separator 1 periphery, aqua storage tank 3 is connected with drain opening 12.Aqua storage tank 3 is provided with flow-off 31, and the level height of flow-off 31 is higher than the level height of drain opening 12.
Exhaust ports also is covered with condensate water recovery device 4 in the upper end of silencer 2, and the inlet that condensate water recovery device 4 is provided with is connected with the relief opening of silencer 2, and the water dropping openings that condensate water recovery device 4 is provided with is positioned at the top of aqua storage tank.
Working principle is, suction port 11 is connected with the relief opening of wet vacuum pump, the gas-vapor mix body that wet vacuum pump is discharged tangentially enters moisture separator by suction port 11, form the air-flow of rotation, under the effect of centrifugal force and gravity, moisture is thrown on the wall of moisture separator and is accumulated in the bottom of moisture separator, after drain opening 12 flow in the aqua storage tanks 3, because drain opening 12 is lower than flow-off 31, therefore drain opening 12 is in the state that is not had by water logging, the noise that the gas that a part is overflowed through drain opening 12 produces is by the water layer filtering, remaining gas enters silencer 2 through separating opening 13 and porous slab 21, reduce noise after porous slab 21 enters condensate water recovery device 4 through sound-absorbing material 22, the moisture that contains in the gas is condensed into water droplet on condensate water recovery device 4, and finally drops onto in the aqua storage tank 3 of condensate water recovery device 4 belows.
Embodiment 2,
All the other are identical with embodiment 1, and difference is that moisture separator 1 is provided with a spherical cavity, and suction port 11 tangentially is communicated in spherical cavity.The air resistance coefficient of spherical cavity is littler, and the swirling eddy of its generation is more powerful, and the aqueous vapor separating effect is better.This cavity also can adopt taper shape.
In the foregoing description, can be connected by water pipe between condensate water recovery device 4 and the aqua storage tank 3, aqua storage tank 3 can seal like this, avoids dust etc. to pollute recycle-water in the aqua storage tank 3.
Adopt the beneficial effect of the technical program to be: to adopt moisture separator and silencer to carry out aqueous vapor and separate the recovery and the processing of eliminating the noise, both reclaimed sealing water and saved resource, make the noise reduction again and meet NBS.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
