Abstract
The utility model discloses a kind of screw vacuum pump exhaust gas cooler, including cooler body and baffle part；Cooler body is the kettle shape structure of a jacketed and top cover；Cooler body is provided with inlet exhaust gas, offgas outlet, cooling water inlet, coolant outlet and waste liquid outlet；Baffle part includes fix bar and flow-stopping plate；Fix bar is fixedly mounted on below the top cover of cooler body；Flow-stopping plate is fixedly mounted on below fix bar and is obliquely installed.Screw vacuum pump exhaust gas cooler of the present utility model makes screw vacuum pump operation more steady, reduces mechanical oscillation and equipment noise, reduces equipment failure rate；When unstable air-flow by when, air-flow by flow-stopping plate act on reduce flow velocity, increase the residence time, enhance the effect of the condensation of waste gas, reduce the discharge of harmful substance in waste gas, reduce environmental pollution.
Description
Technical field
It the utility model is related to a kind of screw vacuum pump exhaust gas cooler.
Background technology
Lubricating oil is not required in screw vacuum pump working chamber, consumption power is low, has the advantages that energy-conservation, freedom from repairs, extensively should
For industries such as microelectronics, semiconductor, pharmacy, Precision Machinings.
Screw vacuum pump can produce a certain amount of waste gas during use, especially carry out organic solvent concentration and
During solid is dried.In order to reduce the discharge capacity of screw vacuum pump waste gas, producer all can install one in vavuum pump gas outlet
Individual cooler.
Cooling coil is installed inside traditional cooler, leads to refrigerant cooled exhaust gas in coil pipe.Due to discharging unstable gas,
Cooling coil can not play a part of eliminating the noise, stop air-flow again, cause operation noise big.
Further, since effluent air temp is high and flow is unstable, although after coil pipe cools down, it is condensable a part of molten
Agent composition, but still there is major part to enter tail gas absorbing system.
Utility model content
The purpose of this utility model is to solve the above problems, there is provided one kind can reduce noise, reduce waste gas discharge, drop
The screw vacuum pump exhaust gas cooler of low environment pollution.
Realizing the technical scheme of the utility model purpose is：A kind of screw vacuum pump exhaust gas cooler, including
Cooler body and baffle part；The cooler body is the kettle shape structure of a jacketed and top cover；It is described cold
But device body is provided with inlet exhaust gas, offgas outlet, cooling water inlet, coolant outlet and waste liquid outlet；The baffle
Part includes fix bar and flow-stopping plate；The fix bar is fixedly mounted on below the top cover of the cooler body；The baffle
Plate is fixedly mounted on below the fix bar and is obliquely installed.
The quantity of the fix bar is four；The quantity of the flow-stopping plate is two pieces, and is staggered installation of up and down in described cold
But the inwall both sides of device body.
The good effect that the utility model has：Screw vacuum pump exhaust gas cooler of the present utility model makes screw vacuum pump
Operation is more steady, reduces mechanical oscillation and equipment noise, reduces equipment failure rate；When unstable air-flow by when, gas
Stream is acted on by flow-stopping plate reduces flow velocity, increases the residence time, enhances the effect of the condensation of waste gas, reduce nuisance in waste gas
The discharge of matter, reduces environmental pollution.
Brief description of the drawings
Fig. 1 is screw vacuum pump exhaust gas cooler structural representation of the present utility model.
Embodiment
Referring to Fig. 1, screw vacuum pump exhaust gas cooler of the present utility model includes cooler body 1 and baffle part 2.
Cooler body 1 is the kettle shape structure of a jacketed 11 and top cover 12；Cooler body 1 is provided with inlet exhaust gas 1-
1st, offgas outlet 1-2, cooling water inlet 1-3, coolant outlet 1-4 and waste liquid outlet 1-5.
Baffle part 2 includes four fix bars 21 and two pieces of flow-stopping plates 22；Four fix bars 21 are fixedly mounted on cooling
The lower section of top cover 12 of device body 1；Every piece of flow-stopping plate 22 is fixedly mounted on two lower sections of fix bar 21 and is obliquely installed.Two pieces of baffles
Plate is staggered installation of about 22 in the inwall both sides of cooler body 1, and underlying flow-stopping plate 22 is towards cooler body 1
Inlet exhaust gas 1-1 directions are obliquely installed.
Screw vacuum pump exhaust gas cooler of the present utility model is as follows using process：By cooling water from cooling water inlet 1-3
Discharged into the chuck 11 of cooler body 1, and from coolant outlet 1-4.The gas come out from screw vacuum pump is from tail gas
Import 1-1 enters in cooler body 1 and is condensed into liquid along path flows as defined in flow-stopping plate 22, the higher gas of boiling point
Body, discharged through waste liquid outlet 1-5, the gas not condensed is discharged through offgas outlet 1-2, delivers to tail gas absorbing system.When not
Steady air flow by when, air-flow by flow-stopping plate 22 effect reduce flow velocity, increase the residence time, both reduce noise, again strengthen
The effect of condensation.
