Description
Technical field
The invention belongs to cornstarch wet production field, refers in particular to the high temperature drying produced to byproduct production process
The reuse method of tail gas.
Background technology
After being dried using pipe bundle drier during cornstarch wet production byproduct at present, high-temperature tail gas are direct
Discharge, this partial tail gas calorific value are very high, and directly discharge causes very big energy waste, corn deep processing traditional drying, evaporator man
Tail gas is dried using byproduct in skill directly to discharge, and corn steep liquor evaporation directly carries out heating evaporation with initial steam, starch is dried
Hot blast is also to be directly heated using initial steam, and its weak point is:Excessive primary energy is consumed, the wasting of resources is processed into
This height;It is dried tail gas sulphur dioxide content high, pollutes environment.
The content of the invention
The present invention provide it is a kind of recycled and combined with heat pump the method for realizing energy-conservation to being dried tail gas, to solve
It is dried tail gas and directly discharges the excessive primary energy of consumption for causing, the wasting of resources, high processing costs, content of sulfur dioxide is high, make
Into the problem of pollution environment.
The present invention is adopted the technical scheme that:Comprise the following steps:
(1)Live steam enters pipe bundle drier, and byproduct is dried, and the tail gas produced after being dried enters scrubbing tower, will
Impurity in tail gas is washed away, while removing sulfur dioxide, detergent adopts weak lye,
(2)Tail gas Jing blower fans one after washing send tail gas into evaporation heating chamber one, are evaporated concentration, tail gas to dilute corn steep liquor
Separation chamber one is entered in emptying, mixture,
(3)The indirect steam of generation is pressurizeed through heat pump, improves 20 ~ 25 degree, and the indirect steam of high heating value is steamed into remaining
Heating chamber two is sent out, mixture enters separation chamber two,
(4)The on-condensible gas of generation carries out condensate drainage into condenser, and condenser is cooled down by cold medium recirculated water, together
When cold medium Jing circulating pumps after condenser heat exchange squeeze into the preheater of Starch Drying System, air-cooled rear cold medium is being entered
Enter condenser,
(5)Air after preheating is mixed with wet starch after heater, is siphoned away by blower fan, expansion drying, realizes that starch is dried
Process.
It is an advantage of the invention that by making full use of to primary energy, reaching energy-saving and emission-reduction, reduce production and consume, enter
And reduce production cost;Present invention saves steam, reduces 0.2 ton/ton starch of steam mono-consumption, sulfur dioxide (SO2) emissions 40% are reduced.
Description of the drawings
Fig. 1 is the flow chart of the present invention.
Specific embodiment
Comprise the following steps:
(1)Live steam enters pipe bundle drier 1, and byproduct is dried, and the tail gas produced after being dried enters scrubbing tower 2,
Impurity in tail gas is washed away, while removing sulfur dioxide, detergent adopts weak lye,
(2)Tail gas Jing blower fans 1 after washing send tail gas into evaporation heating chamber 1, are evaporated concentration, tail to dilute corn steep liquor
Gas is emptied, and mixture enters separation chamber 1,
(3)The indirect steam of generation carries out pressurization temperature raising through heat pump 6, improves 20 ~ 25 degree, and the indirect steam of high heating value enters which
Remaining evaporation heating chamber 27, mixture enter separation chamber 28,
(4)The on-condensible gas of generation carries out condensate drainage into condenser 9, and condenser 9 is cooled down by cold medium recirculated water,
Cold medium Jing circulating pumps 10 after condenser heat exchange squeeze into the preheater 11 of Starch Drying System, air-cooled rear cold Jie simultaneously
Matter into condenser 9,
(5)Cold air after preheating is mixed with wet starch after heater 12, is siphoned away by blower fan 13, expansion drying, realizes forming sediment
Powder dry run.
The byproduct of cornstarch wet production is dried using pipe bundle drier, and its mode of heating is to be passed through primary steam to enter
Row tube bank temperature raising, temperature reach 150 ~ 180 degrees Celsius, and the byproduct after dehydration includes fiber, plumule, albumen powder, and moisture exists
Between 55-60%, this partial material enters pipe bundle drier, and 80-100 degrees Celsius of generation of tail gas removes thing by washing
Dust in material, sulfur dioxide gas etc., into the one of evaporation heating chamber of multi-effect evaporator, carry out adding to corn thin pulp
Heat, the flash steam of generation is carrying out heat pump supercharging, then is passed through remaining evaporation oven heats evaporation, the final on-condensible gas for producing
Into condenser, after the cold medium fluid heating of condenser, preheater is passed through, cold air heating is carried out, medium fluid is through wind
Enter back into condenser to condense on-condensible gas after cold, and then form circulation;Cold air after preheating after heater with wet shallow lake
Powder mixes, and is siphoned away by blower fan, expansion drying, realizes starch dry run.
