Description
Affiliated technical field
The present invention relates to a kind of steam waste heat of saving water and energy for feed granulating and utilize system, especially a kind of novel facility for granulating that in feedstuff pelletization technology, is provided with steam heat recovery utilization and condensed water recycling.
Background technology
The granulator that is used for granulating process in the feed processing is all higher to the requirement of quality of steam, and requirement must be the dry saturated steam that does not contain condensed water, otherwise can affect the control of finished product moisture content.And the steam-water separator in traditional granulating process, its water of separating is with a small amount of steam, and temperature is higher, and feed factory often all is directly to drain by drain valve, does not use to cause energy dissipation.
On the other hand, molasses are a kind of good feedstuffs, because it is the relatively poor thick material of a kind of flowability, want it is added in the feed easily as feedstuff, must reduce by heating its viscosity.
Although Chinese utility model patent CN201393519 has also provided relevant structure, but its utilization for steam waste heat also is not very thorough, be that the higher condensed water of remaining temperature has directly discharged, energy maximization ground do not utilized that water resource also is wasted simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of steam waste heat of saving water and energy for feed granulating to utilize system that the residual steam of granulating process is used for heating molasses, remaining hot water for circulation generation steam, to solve the problems such as energy dissipation in the existing equipment.
Technical scheme of the present invention is achieved in that this steam waste heat of saving water and energy that is used for feed granulating utilizes system to comprise granulator quality-adjusting device, steam-water separator, heater, air inlet pipe, drainpipe, molasses head tank, water tank, the steam generator that connects by pipeline.
Be connected by at least one stop valve between granulator quality-adjusting device and the steam-water separator; Steam-water separator also is connected with drain valve by at least one stop valve; Drain valve is connected with at least one magnetic valve, and wherein the first magnetic valve is connected with heater in the molasses head tank; The second magnetic valve directly is connected with drainpipe, and electronic thermostat is electrically connected and controls its action with the first magnetic valve, the second magnetic valve respectively; Drainpipe is connected with water tank, and water tank is connected with steam generator; The steam that steam generator produces is connected with steam-water separator by air inlet pipe.
Wherein, heater adopts heating tube, and steam generator adopts steam boiler, and the material of steam-water separator is corrosion-resistant stainless steel.
The invention has the beneficial effects as follows: energy-saving and emission-reduction, steam waste heat can greatly be saved molasses processing cost and exhaust-gas treatment cost as the required heat of heating molasses, the condensed water that produces behind the steam utilization flows in the water tank, can be with the water preheat to 50 in the water tank～70 °, water in the water tank is after entering steam boiler, only needing just can be next the temperature rise with fuel seldom, has reduced the consumption of fuel, and heat contained in the condensed water also is fully utilized.Therefore, so that the present invention has higher promotional value and using value.

The specific embodiment
Below, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.Need to prove before this, employed term or word can not limited interpretation be the implication in common implication or the dictionary in this specification and claims book, and should be based in order to illustrate that in the best way principle that its invention inventor can suitably define the concept of term is interpreted as meeting implication and the concept of the technology of the present invention thought.Thereupon, the structure that represents in the embodiment that this specification is put down in writing and the accompanying drawing is one of most preferred embodiment of the present invention, can not represent technological thought of the present invention fully, therefore should be understood that to have for the present invention various equivalents and the variation that can replace.
In Fig. 1; steam waste heat of the present invention utilizes in the system; air inlet pipe 12 connects steam-water separator 10; steam-water separator 10 links to each other with the second stop valve 2 with the first stop valve 1; two stop valves connect granulator quality-adjusting device 9; steam-water separator 10 also is connected with drain valve 5 by the 3rd stop valve 3 and the 4th stop valve 4; drain valve 5 is connected with the first magnetic valve 6 and the second magnetic valve 7; the first magnetic valve 6 and the second magnetic valve 7 are used for the Push And Release of the heater (heating tube) 11 of control molasses head tank 14; and respectively by electronic thermostat 8 control its switch motions (not shown in the part accompanying drawing that magnetic valve is electrically connected with temperature controller); wherein; heating tube 11 in the first magnetic valve 6 and the molasses head tank 14 is connected; heating tube 11 is connected with drainpipe 13, and the second magnetic valve 7 directly links to each other with drainpipe 13.Drainpipe 13 is connected with water tank 15, and water tank 15 is connected with steam generator 16; The steam that steam generator 16 produces enters steam-water separator 10 by air inlet pipe 12.
Operating principle of the present invention and using method are as follows: steam at first enters steam-water separator 10 by air inlet pipe 12, and steam-water separator 10 is for separating of moisture content and steam, enters granulator quality-adjusting device 9 through the first stop valve 1, the second stop valve 2 after isolating moisture content; Isolated condensed water is through the 4th stop valve 4, automatically discharges hot water with a small amount of steam with for the next step by drain valve 5; 3 auxiliary bypass action of the 3rd stop valve wherein, for subsequent use can't normal operation the time in order to the 4th stop valve 4, close at ordinary times.
When the temperature of molasses in the molasses head tank 14 is lower than the design temperature of electronic thermostat 8, the first magnetic valve 6 is opened in electronic thermostat 8 controls, close the second magnetic valve 7, hot water enters heating tube 11 in the molasses head tank 14 through the first magnetic valve 6, utilize heating tube 11 heating molasses by heat transfer effect, then it can be added in the feed as feedstuff after the viscosity of reduction molasses.When the temperature of molasses in the molasses head tank 14 is higher than the design temperature of electronic thermostat 8, then the second magnetic valve 7 is opened in electronic thermostat 8 controls, close the first magnetic valve 6, hot water is directly drained through the second magnetic valve 7 drainpipe 13 of flowing through, and does not enter in the heating tube 11 and heats molasses.Hot water after the utilization drainpipe 13 of flowing through at last drains into water tank 15 and the water in the water tank 15 is carried out preheating, (water temperature is slightly hanged down about 50 ° behind the heating molasses generally can be heated to 50～70 °, the water temperature of directly discharging is slightly high about 70 °), and then for steam generator 16 circulation generation steam.
