Abstract
A kind of riboflavin extraction device for recovering tail gas is the utility model is related to, including the plate type heat exchanger and cyclone separator being sequentially connected with offgas duct, the gas outlet of the cyclone separator are connected with return duct, the return duct is in a high position for gas outlet；The return duct includes vertical pipeline and horizontal pipe, and the vertical pipeline is provided with reducer, and the diameter of the reducer is more than the diameter of vertical pipeline；The outlet of the return duct is connected with waste gas holding vessel.The device for recovering tail gas of this programme is used to substitute spray tower systems of the prior art, can reduce equipment investment, and saves operation and maintenance cost.
Description
Technical field
A kind of riboflavin extraction device for recovering tail gas is the utility model is related to, belongs to riboflavin production equipment technology.
Background technology
Riboflavin is the product obtained from fermented and a series of processing for raw material with gelatine, rice bran oil and corn steep liquor etc..
In riboflavin extraction process, the high-temperature tail gas for being mingled with pollutant can be produced, water, riboflavin, thalline are generally comprised in tail gas,
If directly discharged, environmental pollution will be caused；Typically tail gas is washed and cooled using spray column in the prior art, afterwards
Tail gas is subjected to recovery storage again.It is larger to there is equipment investment by the way of spray column, operation and maintenance cost it is high the problem of.
The content of the invention
The purpose of this utility model is to provide a kind of riboflavin extraction device for recovering tail gas, to solve the above problems, tool
Body scheme is：
A kind of riboflavin extracts device for recovering tail gas, including the plate type heat exchanger and cyclonic separation being sequentially connected with offgas duct
Device, the gas outlet of the cyclone separator are connected with return duct, and the return duct is in a high position for gas outlet；The return duct bag
Vertical pipeline and horizontal pipe are included, the vertical pipeline is provided with reducer, and the diameter of the reducer is more than the straight of vertical pipeline
Footpath；The outlet of the return duct is connected with waste gas holding vessel.
Further, the reducer is located at the top of vertical pipeline.
Further, the lower end of the reducer is provided with conical opening.
Further, 1.5 ~ 2 times of a diameter of vertical pipeline diameter of the reducer.
Of the present utility model to be beneficial to point, the device for recovering tail gas of this programme is used to substitute spray column of the prior art
System, equipment investment can be reduced, and save operation and maintenance cost.Concrete principle is that riboflavin extraction tail gas first passes through plate
Formula heat exchanger is cooled, while the heat of tail gas can be recycled；Tail gas after cooling enters cyclone separator, warp
Gas solid separation is crossed, the impurity being mingled with tail gas is reclaimed, the tail gas after processing enters waste gas holding vessel.
This programme is connected with return duct in the gas outlet of cyclone separator, and subsidiary moisture condenses in vertical pipeline in tail gas
After be back to cyclone separator, avoid impacting follow-up equipment；Reducer is set in vertical pipeline, tail gas enters reducer
Afterwards, flow velocity anticlimax, pressure reduce, and can promote moisture condensation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of riboflavin extraction device for recovering tail gas as shown in Figure 1, including the plate-type heat-exchange being sequentially connected with offgas duct 7
Device 1 and cyclone separator 2, the gas outlet of the cyclone separator 2 are connected with return duct, and the return duct is in the height of gas outlet
Position；The return duct includes vertical pipeline 4 and horizontal pipe 5, and the vertical pipeline 4 is provided with reducer 6, the reducer 6
Diameter is more than the diameter of vertical pipeline 4；The outlet of the return duct is connected with waste gas holding vessel 3.The reducer 6 is located at vertical
The top of pipeline 4.The lower end of the reducer 6 is provided with conical opening.The 1.5 of the diameter of a diameter of vertical pipeline 4 of the reducer 6
~ 2 times.
Of the present utility model to be beneficial to point, the device for recovering tail gas of this programme is used to substitute spray column of the prior art
System, equipment investment can be reduced, and save operation and maintenance cost.Concrete principle is that riboflavin extraction tail gas first passes through plate
Formula heat exchanger is cooled, while the heat of tail gas can be recycled；Tail gas after cooling enters cyclone separator, warp
Gas solid separation is crossed, the impurity being mingled with tail gas is reclaimed, the tail gas after processing enters waste gas holding vessel.
This programme is connected with return duct in the gas outlet of cyclone separator, and subsidiary moisture condenses in vertical pipeline in tail gas
After be back to cyclone separator, avoid impacting follow-up equipment；Reducer is set in vertical pipeline, tail gas enters reducer
Afterwards, flow velocity anticlimax, pressure reduce, and can promote moisture condensation.
