Description
Technical field
The utility model belongs to corn deep processing technology field, preheats and heats more particularly to a kind of starch dry air
Device.
Background technology
Cornstarch is also known as corn starch, popular name maize powder, the white flaxen powder of micro-strip.Corn is sub- with 0.3%
After sulfuric acid dipping, it is made up of the process such as broken, sieving, precipitation, dry, levigate.In mill run containing a small amount of fat and
Protein etc..Hygroscopicity is strong, can be up to more than 30%.
The drying program of cornstarch is the transport and storage for the ease of cornstarch, and starch moisture content is reduced to
12% equilibrium water conten, then dispatched from the factory as finished product dried starch.
In some places, winter temperature is low, and so as to cause, the heat exchanger heat transfer effect during corn drying is poor, condensate liquid
The problems such as outlet obstruction, the tubulation of air preheater freeze, reduces quality and efficiency that cornstarch is dried.
The content of the invention
In view of the above-mentioned problems of the prior art, the utility model provides a kind of good effect of heat exchange, energy-saving, reduction
The starch dry air warmup heater that production cost, operating efficiency are high, cornstarch dry mass is high.
Technical solution adopted in the utility model is：Starch dry air warmup heater, including heat exchanger, storage tank,
Centrifugal pump and multiple starch dry air preheaters；The heat exchanger be provided with evaporation waste heat import, condensate outlet, inlet and
Liquid outlet；The inlet of the storage tank is connected with the liquid outlet of heat exchanger by pipeline one, the import of the centrifugal pump and storage tank
Liquid outlet connected by pipeline two, the outlet of the inlet and centrifugal pump of the multiple starch dry air preheater passes through pipe
Road tee joint, the liquid outlet of multiple starch dry air preheaters are connected with the inlet of heat exchanger by pipeline four.
The beneficial effects of the utility model are：
Concentration is that 30% ethylene glycol solution enters storage tank with evaporation waste heat after heat exchanger heat-shift by the utility model
In, injected under the active force of centrifugal pump in starch dry air preheater, with removing heat exchanger again after the cold air heat exchange in the external world,
Return in storage tank, repetitive cycling, reach heat transfer effect, be i.e. solution winter temperature is low, and heat transfer effect is poor, has reached energy-conservation drop again
The policy of consumption, production cost is reduced, and operating efficiency is high, cornstarch dry mass is high.
Brief description of the drawings

Wherein：1- heat exchangers；2- storage tanks；3- centrifugal pumps；4- starch dry air preheaters.
Embodiment
As shown in figure 1, starch dry air warmup heater, including heat exchanger 1, storage tank 2, centrifugal pump 3 and multiple starch
Dry air preheater 4；The heat exchanger 1 is provided with the import of evaporation waste heat, condensate outlet, inlet and liquid outlet；Heat exchanger 1
The import of evaporation waste heat be used to introduce evaporation waste heat, the condensate outlet of heat exchanger 1 is used to exclude condensate liquid, the storage tank 2
Inlet is connected with the liquid outlet of heat exchanger 1 by pipeline one, and the import of the centrifugal pump 3 passes through pipe with the liquid outlet of storage tank 2
Road two connects, and the inlet of the multiple starch dry air preheater 4 and the outlet of centrifugal pump 3 are more by pipeline tee joint
The liquid outlet of individual starch dry air preheater 4 is connected with the inlet of heat exchanger 1 by pipeline four.
The medium that the multiple starch dry air preheater 4 uses is 30% ethylene glycol solution, 30% ethylene glycol solution
Fusing point be -13.2 DEG C.
One ton of starch gas consumption reduces, and saves the consumption of fire coal, and production cost reduces, and computational methods are as follows：
1. data
1.1 ethylene glycol

1.4 combined-circulation once-through boiler thermal efficiency η=90%
2. adjust
Mixing specific heat capacity, the density of 2.1 ethylene glycol solutions
CP=4.063KJ/kg. DEG C, hybrid density ρ=1034.7kg/m3
The heat energy and consumed energy that 2.2 circulatory systems absorb
E1=23434936.31KJ/h, 0.981MPaG, 200 DEG C of steam enthalpy H=2821.18KJ/kg
Circulating pump consumes electric energy E2=45KW, as162000KJ/h, net to obtain energy Δ E=2.3E+07KJ/h
As steam 8.25t/h.as mark coal amount m=3.694t marks coal/has88.66t marks coal/d30144t marks coal/a
The full cost of steam steam presses 90 yuan/t, obtains source benefit=742.44 yuan/h=17818.6/d=605.83 ten thousand yuan/a
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
