Abstract
The utility model relates to a heat energy recovering system for beer plant, which comprises a heat energy tank and a heat exchanger for preheating wheat juice; wherein, the intermediate water intake and outlet on the heat exchanger are respectively connected with the heat energy tank through pipes. The utility model also includes a direct-contact heat exchanger, which is provided with an entrance connected with a second steam tube, and intermediate water intake and outlet that also connect with the said heat energy tank through their own pipes. Compared with prior art, and due to direct contact of second steam and water, the utility model has the advantages of simple device, low cost and high heat exchange efficiency. In addition, the temperature of the intermediate water can be heated equal to that of the second steam, increasing the preheating temperature difference of wheat juice which is better for wheat juice preheating and reduces heat transfer area of wheat juice preheater, thereby, the utility model makes full use of afterheat and effectively prevents energy loss, deserving renovation on prior device and application.
Description
Technical field
The utility model relates to a kind of heat reclaiming system, especially refers to a kind of being applied in the brewery, and the heat of the indirect steam that produces during with Wort boiling is used for preheating wheat juice, to reach the heat reclaiming system that reclaims the indirect steam heat.
Background technology
In beer production, need earlier wheat juice to be boiled, and can produce indirect steam during Wort boiling.In order to reclaim the heat of this indirect steam in time, existing brewery is furnished with heat reclaiming system usually.This heat reclaiming system comprises dividing wall type pipe bundle condenser, heat energy storage tank and dividing wall type baffle heater, and the middle water import and export of condenser, the heater pipeline by separately respectively is communicated in the heat energy storage tank.During recovery, with indirect steam condensation in above-mentioned condenser of wheat juice, with the middle water in the heats cold condenser; Because Wort boiling has intermittence, therefore the middle water after the heating is stored in the heat energy storage tank by pipeline earlier; When the needs preheating wheat juice, again the hot water in the heat energy storage tank is fed in the above-mentioned heater then; Middle water after the last heat exchange returns the heat energy storage tank, goes to obtain required heat from condenser again, goes round and begins again like this, reaches the purpose that reclaims indirect steam.But find that in actual applications this dividing wall type heat transfer type makes equipment comparatively complicated on the one hand, and the price height, cost of investment is big; Also must possess certain heat transfer temperature difference on the other hand, and the temperature of middle water is lower than the indirect steam temperature forever.Obviously, such system's heat exchange efficiency is low.
Summary of the invention
Technical problem to be solved in the utility model is the defective that overcomes prior art, and the brewery that a kind of cost is low, heat exchanger effectiveness is high heat reclaiming system is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this brewery's heat reclaiming system comprises the heat exchanger of heat energy storage tank and preheating wheat juice, middle water import and export on the described heat exchanger is communicated in described heat energy storage tank by pipeline respectively, it is characterized in that: also comprise a direct-contact heat exchanger, offer the inlet that is connected with secondary steam pipe and inlet opening, the apopore of middle water on this direct-contact heat exchanger, described into and out of the water hole also respectively the water pipe by separately be connected with above-mentioned heat energy storage tank.
Described heat energy storage tank can be for a plurality of, and are in series mutually.
Compared with prior art, because the utility model directly contacts indirect steam with water, so equipment is simple relatively, cost is low, and heat exchanger effectiveness height, simultaneously middle water can also be heated to the temperature equal with indirect steam, the temperature difference that preheats of wheat juice is strengthened, more help the preheating of wheat juice, wheat juice preheater heat transfer area is reduced, thereby the utility model can make full use of waste heat, can prevent the loss of energy effectively, so be worth transforming on the existing apparatus, using.
Description of drawings
Fig. 1 is the system schematic of the utility model embodiment;
Fig. 2 is the energy recovery schematic diagram of the utility model embodiment.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, this brewery's heat reclaiming system comprises the dividing wall type plate type heat exchanger 3 of direct-contact heat exchanger 1, heat energy storage tank 2 and preheating wheat juice, wherein, offer the inlet that is connected with secondary steam pipe on the direct-contact heat exchanger 1, the apopore and the inlet opening of water in the middle of the position also is provided with simultaneously thereon, down, and the inlet opening of this centre water, apopore respectively the water pipe by separately be connected with above-mentioned heat energy storage tank 2.And the middle water import and export on the dividing wall type plate type heat exchanger 3 also is communicated in described heat energy storage tank 2 by pipeline respectively.For hot and cold middle water is flowed apace, on above-mentioned pipeline, also be equipped with heat-exchanger pump 4.
In such scheme, described heat energy storage tank 2 is two, and is in series mutually.
When the Wort boiling in the boiling pot 5, the indirect steam of its generation is flowed in the direct-contact heat exchanger 1 by steam pipe 6, be after indirect steam middle water direct and in the direct-contact heat exchanger 1 contacts, with the middle water in the heating direct-contact heat exchanger 1, after middle water absorbed heat, its temperature can reach 98 °～99 °.Then, the middle water after the heating is stored in the heat energy storage tank 2.When treating that wheat juice needs preheating, again the hot water in the heat energy storage tank 2 is flowed into dividing wall type plate type heat exchanger 3, after the release heat, wheat juice is preheated, and simultaneously, the middle water of low temperature is got back in the heat energy storage tank 2 again, so go round and begin again, realize the purpose that heat energy fully reclaims.
