Abstract
The utility model relates to a venturi latent heat recovery device. The venturi latent heat recovery device is equipped with a spray device, a coarse distillation tower, a vacuum tank, a separating tank, a water storage tank, a control valve and a pipeline; the venturi latent heat recovery device is characterized in that a venturi tube is arranged on the spray device and connected with the coarse distillation tower by a pipeline with a control valve, wherein produced steam enters the vacuum tank by the pipeline to generate negative pressure on the vacuum tank; after rapid flash evaporation, secondary stream is generated to return to the coarse distillation tower, and the work circulates, so that energy-saving and consumption-lowering is sufficiently realized. The venturi latent heat recovery device disclosed by the utility model can be applied to recovery of alcohol and vinegar, is simple to operate and novel in design.
Description
Technical field
The utility model relates to a kind of recovery of latent heat device for alcohol, vinegar, specifically a kind of venturi recovery of latent heat device.
Background technology
We know, at present, in alcohol, vinegar removal process, topping still produces a large amount of high-temperature-hot-waters, wherein produces heat energy and much all can slattern; And the effect that most recovery of latent heat device is not accomplished sharply flash distillation in removal process still has a large amount of indirect steams to be wasted, make the energy can not get effective utilization.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of low price and energy-efficient is provided, and is easy to the venturi recovery of latent heat device for alcohol, vinegar reclaimer regulating.
The utility model solves the problems of the technologies described above taked technical scheme: a kind of venturi recovery of latent heat device, be provided with injection apparatus, topping still, vacuum tank, knockout drum, water tank, control valve, pipeline, it is characterized in that: described injection apparatus is provided with two, in injection apparatus all with venturi pipeline, injection apparatus is connected with topping still by pipeline, described vacuum tank is divided into one-level vacuum tank and secondary vacuum tank, topping still is connected with one-level vacuum tank by pipeline, one-level vacuum tank is connected with water tank by pipeline, the gas producing in described one-level vacuum tank is got back to topping still by pipeline, the high-temperature-hot-water producing enters secondary vacuum tank by pipeline, secondary vacuum tank bottom is connected with knockout drum by pipeline, on described pipeline, be equipped with control valve.
The utility model is owing to taking said structure, and high-temperature steam can enter topping still by venturi recovery of latent heat device, produces larger pressure differential and pressure reduction stable, is the recovery of latent heat device of a kind of energy-efficient alcohol, vinegar.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, be labeled as: 1. injection apparatus, 2. topping still, 3. one-level vacuum tank, 4. secondary vacuum tank, 5. injection apparatus, 6. water tank, 7. knockout drum, 8. control valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, the utility model relates to a kind of venturi recovery of latent heat device, comprise injection apparatus 1, topping still 2, one-level vacuum tank 3, secondary vacuum tank 4, injection apparatus 5, water tank 6, knockout drum 7, control valve 8, it is characterized in that: high steam produces negative pressure (0.06MPa) by injection apparatus 1 and 5, enter topping still 2, the high-temperature-hot-water that topping still 1 is discharged enters one-level vacuum tank 3 by water tank 6, by flash distillation sharply, produce a large amount of indirect steams, get back to topping still 2, the hot waste water (approximately 110 DEG C) producing enters secondary vacuum tank 4 by pipeline, after continuing to be flashed, waste water is discharged by knockout drum 7.
When the utility model uses, high steam, through 1,5 injection apparatus, produces negative pressure (0.06MPa) to 3 one-level vacuum tanks, 2 topping stills are discharged 110 DEG C of high-temperature water, sharply flash distillation, produces a large amount of indirect steams, and indirect steam is sucked and mixes by the primary steam from boiler, get back to 2 topping stills, to topping still heating, hot waste water enters 4 secondary vacuum tanks, continues to be flashed, carry out secondary deep and reclaim indirect steam, the indirect steam of recovery is got back to again and in topping still, is recovered utilization.Through secondary recovery of latent heat, two-stage flash waste water can drop to 82 DEG C by 110 DEG C, has fully realized energy-saving and cost-reducing.
In sum, the utility model can be widely used in the industry such as alcohol, vinegar, and compared with most of recovery of latent heat device of present use, pressure differential is stable, and energy-efficient, applicability is strong.
