Description
Technical field
The present invention relates to a kind of device for recovering tail gas, more particularly to a kind of device for recovering tail gas for vavuum pump.
Background technology
Volatile solvent is reclaimed commonly using oilless vertical vacuum pump in Chemical Manufacture, vavuum pump is a kind of rotation
Formula positive displacement vacuum pump, which must have fore pump cooperation side to may be used in wider pressure limit, has larger pumping speed by waving in container
Hair property gas is extracted out, but in use, vacuum pump exhaust port is probably due to sealing not exclusively causes inevitably row
Go out a part of solvent vapo(u)r, cause solvent loss, pollute air ambient.
The content of the invention
The purpose of the present invention is that provides a kind of device for recovering tail gas for vavuum pump to solve the above problems.
The present invention is achieved through the following technical solutions above-mentioned purpose：
A kind of device for recovering tail gas for vavuum pump, including vavuum pump and tail gas recycle pipe, the tail gas of the vavuum pump
Floss hole is connected with the tail gas recycle pipe, and the retracting device also includes blast pipe and condensing unit, and the blast pipe is installed
Between the exhaust port and the tail gas recycle pipe of the vavuum pump, the condensing unit is arranged on the blast pipe.
When solvent vapo(u)r is discharged into tail gas recycle pipe by vavuum pump, because can through the blast pipe for possessing condensing unit,
It can be made to be condensed into liquid reagent steam cooling, because liquid reagent is difficult leakage than gaseous reagent, it can be reduced
Volatility.
Specifically, the condensing unit is made up of condenser pipe with the condenser equipped with chilled brine, the condenser pipe winding
On the blast pipe, the two ends of the condenser pipe are connected with the water inlet and delivery port of the condenser respectively.This device is used
Cool in for blast pipe, accelerate steam reagent therein and condense liquefaction.
Preferably, pacifying between the joint and the exhaust port and the tail gas recycle pipe at the blast pipe two ends
Equipped with corrosion-resistant sealing ring.
Further, the retracting device also includes safety bag, the joint of the exhaust port, the blast pipe and described
The joint of tail gas recycle pipe is arranged in the safety bag, and the condenser is arranged on outside the safety bag.
Preferably, between the safety bag and the exhaust port, the tail gas recycle pipe and the condenser pipe
Using being tightly connected.
This structure is used to, when occurring chemical vapor leakage, to be first collected in safety bag, it is to avoid directly discharge
Into air, environment is protected, is tightly connected while safety bag is also used with perimeter component, the present invention is provided with dual-seal
The function of protection.
Further, it is provided with gas sensor in the safety bag.This device is used to transmit out steam leakage in time
Signal.
The beneficial effects of the present invention are：
The present invention uses increase blast pipe and condensing unit for the device for recovering tail gas of vavuum pump, accelerates solvent vapo(u)r
Cooling, reduces the probability of its leakage, while setting safety bag and gas sensor outside blast pipe, it is let out in steam generation
Alarm can be timely sent during dew and by the gas collection of leakage in safety bag, it is to avoid be directly discharged to pollute empty in air
Gas.
Brief description of the drawings
Fig. 1 is structural representation of the present invention for the device for recovering tail gas of vavuum pump, shows the interior of safety bag in figure
Portion's structure.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings：
As shown in figure 1, the present invention is used for the device for recovering tail gas of vavuum pump, including vavuum pump 1, tail gas recycle pipe 8, exhaust
Pipe 4, condensing unit (not shown) and safety bag 10, the exhaust port 2 of vavuum pump 1 are connected with tail gas recycle pipe 8, exhaust
Pipe 4 is arranged between the exhaust port 2 of vavuum pump 1 and tail gas recycle pipe 8, and condensing unit is by condenser pipe 5 and equipped with freezing salt
The condenser 6 of water is constituted, and condenser pipe 5 is wrapped on blast pipe 4, and the two ends of condenser pipe 5 are respectively with the water inlet of condenser 6 and going out
The mouth of a river is connected, and corrosion-resistant sealing ring is mounted between the joint 3 and exhaust port 2 and tail gas recycle pipe 8 at the two ends of blast pipe 4
9, the joint of the joint of exhaust port 2, blast pipe 4 and tail gas recycle pipe 8 is arranged in safety bag 10, and condenser 6 is set
Use and be tightly connected outside safety bag 10, between safety bag 10 and exhaust port 2, tail gas recycle pipe 8 and condenser pipe 5,
Gas sensor 7 is provided with safety bag 10.
The present invention is as follows for the operation principle of the device for recovering tail gas of vavuum pump：
The blast pipe 4 that solvent vapo(u)r is cooled down by the device that is condensed first so that solvent vapo(u)r is condensed by cooling, works as reagent
When steam generation is revealed, can first it be collected in safety bag 10, it is to avoid be directly discharged in air, while in safety bag 10
Gas sensor 7 signal of steam leakage transmitted to host computer in time send leak alarms.
Technical scheme is not limited to the limitation of above-mentioned specific embodiment, and every technique according to the invention scheme is done
The technology deformation gone out, each falls within protection scope of the present invention.
