Description
Technical field
The utility model relates to furfural production technical field, is specifically related to a kind of low-boiling point substance in furfural production retracting device.
Background technology
In China's furfural production process, most of producer adds the dilute sulfuric acid of 5% in the corncob mixing crushed, and adds in hydrolysis kettle and is hydrolyzed by steam pressurized; Make its pentosan be hydrolyzed to wood sugar, wood sugar, under H+ ionization, is sloughed three moisture content and is become furfural.Also produce low-boiling-point substance (accounting for 5% of the furfural) hydrolysis such as acetic acid (accounting for 13% of furfural) and methanol acetone in hydrolytic process after, reactant is become stoste by steam as the blowout of aldehyde vapour together and enters primary distillation tower through original fluid container and be separated after condenser condenses simultaneously, general stoste temperature controls between 70-90 DEG C, wherein a methyl alcohol part to be dissolved in stoste a part and to be discharged in air by original fluid container evacuation port, the distillate distilled out through primary distillation tower after condenser condenses in phase-splitter; Phase-splitter temperature controls 40 DEG C, wherein also some methyl alcohol and acetone emptying from the evacuation port of phase-splitter.When water aldehyde to enter after lightness-removing column through condenser condenses, also the discharge of some methanol acetone in an atmosphere, has a strong impact on environment and forms atmosphere pollution.
Summary of the invention
The utility model provides a kind of low-boiling point substance in furfural production retracting device, and the low-boiling-point substance of furfural production existed to solve prior art enters the problem that air pollutes.
The utility model solves the technical scheme that its technical problem adopts:
A kind of low-boiling point substance in furfural production retracting device, primarily of water tank, low-boiling-point substance recovery tower, blower and water pump composition, the air outlet of blower fan communicates with low-boiling-point substance recovery tower tower reactor, water tank is arranged on bottom low-boiling-point substance recovery tower, water tank is arranged water inlet and liquid outlet, water tank outside connects water pump, and the spray equipment that water pump is arranged by pipeline and low-boiling-point substance recovery tower tower top is connected.
Above-mentioned low-boiling-point substance recovery tower upper space arranges some layers of Raschig ring.
Operation principle of the present utility model is: the low-boiling-point substance of the low-boiling-point substance of emptying for furfural production original fluid container discharge, the emptying discharge of furfural production phase-splitter and the low-boiling-point substance of the emptying discharge of furfural production condenser of light component removal column are sucked low-boiling-point substance recovery tower by blower fan, repeatedly absorb to exchange through water for cooling and dissolve, gas is discharged through tower top, and the water being dissolved with low-boiling-point substance enters lightness-removing column from the liquid outlet of water tank; Supplementing water enters water tank by the water inlet of water tank, with water pump, the water circulation of water tank is squeezed into absorption tower, and concrete technology step is as follows:
(1) open the inlet valve of low-boiling-point substance recovery tower bottom water tank, water tank is piled water;
(2) water pump is opened by recirculated water valve open;
(3) start that blower fan is emptying by original fluid container, phase-splitter is emptying, the low-boiling-point substance at de-condenser light evacuation port place sucks in tower simultaneously and carry out down cycles and dissolve and exchange;
(4) sample analysis is when in water tank, low-boiling-point substance mass content reaches 2%, opens the liquid valve gate control water yield and the aqueous solution is entered lightness-removing column recovery low-boiling-point substance, open inlet valve simultaneously and make low-boiling-point substance mass content in water tank remain on the level within 2%.
The utility model device is by emptying to emptying for stoste in furfural production low-boiling-point substance out, phase-splitter low-boiling-point substance out and the emptying low-boiling-point substance out of condenser of light component removal column, by a gas absorption tower, repeatedly absorb with water for cooling, low-boiling-point substance is all dissolved in water, solve the problem because of low-boiling-point substance exhaust emission environment in furfural production, benefit the people.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the utility model device.
1 water tank, 2 low-boiling-point substance recovery towers, 3 blower fans, 4 exhaust outlets, 5 Raschig rings, 6 water pumps, 7 recirculated water valves, 8 water inlets, 9 liquid outlets, 10 spray equipments in figure.
