Specific embodiment
In the description of the present invention, it should be understood that term " longitudinal direction ", " transverse direction ", "upper", "lower", " preceding ",
The orientation or positional relationship of the instructions such as " rear ", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" be based on
Orientation or positional relationship shown in the drawings is merely for convenience of description the utility model, rather than the dress of indication or suggestion meaning
It sets or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to the utility model
Limitation.
The technical solution of the utility model is described in detail in conjunction with attached drawing, a kind of furfural treatment vacuum pump deodorizing device, including
Refine vacuum pump and vacuum pump deodorizing device, it is characterised in that: vacuum pump deodorizing device is removed by blow-down pipe 1, heat exchanger 2 and cooling
Taste device composition, blow-down pipe one end are connected with the vacuum pressure relief opening of purification vacuum pump 4, and the other end is connected with the entrance of heat exchanger
It connects, cooling device is made of exhaust pipe 5, cooling tube 6 and condensing agent, and exhaust pipe is connected with the outlet of heat exchanger, cooling pipe sleeve
It is located at the surface of exhaust pipe, the storage for storing condensing agent is collectively formed in the outer wall of exhaust wall, cooling tube wall and heat exchanger
Gap 7, when purification vacuum pump production furfural needs to wait having for the derivative of aldehyde to the furfural, the acetaldehyde that generate in pump for a period of time
When evil gas discharge, pernicious gas is drained into coupled blow-down pipe by purification vacuum pump, and then is discharged into heat exchanger, is utilized
The gas that boiling point is in 50 DEG C -70 DEG C is carried out cooling liquid by the principle of pernicious gas different boiling, and the gas after making liquefaction is deposited
Stay in heat exchanger, flowed into exhaust pipe without liquefied pernicious gas from the outlet of heat exchanger, exhaust wall, cooling tube wall and
The storage gap for storing condensing agent is collectively formed in the outer wall of heat exchanger, and it is Celsius that the condensing agent of the inside makes exhaust pipe be maintained at 0
Degree, the pernicious gas by the boiling point in exhaust pipe at 0 DEG C -50 DEG C degrees Celsius liquefies, and liquefied pernicious gas is from heat exchanger
Outlet return to heat exchanger in, then periodically recycled to remaining in the pernicious gas after the liquefaction in heat exchanger, effectively
The problem of preventing the pernicious gas loss into air, polluting environment, while by discharge pernicious gas, it is effective to ensure that
The vacuum degree for refining vacuum pump enables the operation for refining vacuum pump long-time, efficient stable.
The outlet of heat exchanger is set to the top of heat exchanger, and exhaust pipe and cooling tube are respectively perpendicular the top for being set to heat exchanger
Portion facilitates liquefied pernicious gas out of, heat exchanger outlet return to heat exchanger, the length of exhaust pipe using gravity principle
Not less than 1.6m, enable resting in exhaust pipe for pernicious gas longer time, keeps pernicious gas liquefaction more abundant.
Because there is the properties of different boiling for pernicious gas, therefore there is part pernicious gas to fail to liquefy and can arrange from exhaust pipe
Out, in order to collect this portion gas, deodorizing device can be installed additional on cooling deodorizing device, deodorizing device adds by eliminating smell agent and automatically
Medicine machine 8, eliminating smell agent is set in automatic medicament feeding machine, the inside that the outlet of automatic medicament feeding machine passes through pipeline 9 and the upper end of exhaust pipe
It is connected, the chemical industry of the preferable liquid of eliminating smell agent sprays eliminating smell agent, after the eliminating smell agent of liquid is atomized by automatic medicament feeding machine, leads to
Piping is discharged into the inside of exhaust pipe upper end, and remaining pernicious gas in exhaust pipe will by the effect of eliminating smell agent catalysis oxidation
Its partial oxidation is discharged at after nitrogen oxides from exhaust pipe, reaches discharge standard, pressuring machine 10 is provided on pipeline, pressuring machine can
It is preferred that gas drive booster pump, the end that pipeline is connected to exhaust pipe is provided with spray head 3, by pressuring machine by the eliminating smell agent after atomization
After pressurizeing and so that the liquid particles of atomization is become smaller and then increase the contact area of eliminating smell agent and pernicious gas, from spray head
Middle discharge enables pernicious gas to carry out sufficient haptoreaction with eliminating smell agent, because of the pernicious gas tool being discharged in purification vacuum pump
There is higher corrosivity, therefore the stainless steel material or aluminum alloy material system of good corrosion resistance can be selected in blow-down pipe and exhaust pipe
At.
The basic principle of the utility model, main feature and advantage has been shown and described above, it is practical new not departing from this
