Abstract
The utility model discloses a liquefaction waste heat reutilization device which is a tubular heat exchanger; the device comprises a shell body and a heat exchange tube in the shell body; the lower part of the heat exchange tube is connected with a maltodextrin serous inlet pipe, and the upper part of the heat exchange tube is connected with a maltodextrin serous outlet pipe; the heat exchange tube is communicated with a quadruple effect evaporator pipeline; the lower end of one side of the shell body is provided with a condensate inlet pipe and is communicated with a hot air device pipeline of a drying tower; and a condensate outlet pipe is arranged on one side of the shell body and is communicated with a boiler pipeline. Compared with the prior art, according to the liquefaction waste heat reutilization device, the condensate formed after the hot air of the drying tower is cooled is fully utilized, the maltodextrin serous to enter a quadruple effect evaporator is preheated, so that the initial temperature of the maltodextrin serous is improved, the fluidity is improved, the spray effect is optimized, and meanwhile the heat consumption is reduced.
Description
Technical field
The utility model relates to a kind of condensed water heat recovery device, is the device of in malt amylin production process, recycling the waste heat of drying heater condensed water, belongs to the corn deep processing equipment technical field.
Background technology
At present, in the corn deep processing industry, be processed into cornstarch in the production process of maltodextrin; Get in the drying tower behind the pre-heating temperature elevation in the four-effect evaporator in the maltodextrin slurries, feed hot blast in the drying tower, maltodextrin slurries heating carrying out concentrate drying; The condensed water that hot blast cooling back forms is then sent into boiler and reused, and the defective of this kind production technology is that the first temperature that makes of maltodextrin slurries in the four-effect evaporator is low, and is mobile poor; Influence spray effect; And the cooled condensate temperature of hot blast is also very high, directly gets into the waste that boiler then causes heat, forms the increase of production cost.
The utility model content
Weak point to the prior art existence; The purpose of the utility model is to provide a kind of liquefaction heat recovery device, and the condensed water that hot blast cooling back is formed makes full use of, and the maltodextrin slurries that are about to get into four-effect evaporator are preheated; Improve the first temperature that makes of maltodextrin slurries; Improve flowability, optimize spray effect, reduce heat exhaustion simultaneously.
To achieve these goals; The technical scheme of the utility model is: a kind of liquefaction heat recovery device; Comprise the tubulation heat exchanger, described tubulation heat exchanger comprises housing, heat exchange tubulation, and described heat exchange tubulation bottom is provided with the entering pipe of maltodextrin slurries; Top is provided with the discharge pipe of maltodextrin slurries, communicates with the four-effect evaporator pipeline; Described housing one side lower part is provided with the water inlet pipe of condensed water, communicates with the hot air apparatus pipeline of drying tower, and housing one upper lateral part is provided with the discharge pipe of condensed water, communicates with boiler tubing.
Compare with prior art; The liquefaction heat recovery device of the utility model makes full use of the condensed water that drying tower hot blast cooling back forms; And the maltodextrin slurries that are about to get into four-effect evaporator are preheated, improved the initial temperature of maltodextrin slurries, improve mobile; Optimize spray effect, reduce heat exhaustion simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with embodiment the utility model is done to specify further.
As shown in Figure 1; The liquefaction heat recovery device of the utility model; Comprise the tubulation heat exchanger, described heat exchange tubulation comprises housing 1, heat exchange tubulation 2, and described heat exchange tubulation 2 bottoms are provided with the entering pipe 3 of maltodextrin slurries; Top is provided with the discharge pipe 4 that connects the maltodextrin slurries, communicates with the four-effect evaporator pipeline; Described housing 1 one side lower parts are provided with the water inlet pipe 6 of condensed water, communicate with the hot air apparatus pipeline of drying tower, and housing 1 one upper lateral parts are provided with the discharge pipe 5 of condensed water, communicate with boiler tubing.
The technical scheme of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical scheme of the utility model all falls within the protection domain of the utility model.
