Description
Technical field
The utility model relates to waste heat recovery utilizing equipment, specifically a kind of pipe bundle drier waste vapour recycle device.
Background technology
At present, in corn starch processing, isolated plumule and fiber is dry through pipe bundle drier, the tube bank secondary waste gas producing when dry directly enters atmosphere by blower fan after by cyclone dust collectors, the tube bank condensed water producing directly discharged or lower the temperature after do starch washing water and use, in the dry run of starch, the condensed water that starch pneumatic conveying drying radiator produces directly discharged or lower the temperature after do starch washing water and use, wherein restrain secondary waste gas and have the high temperature of 110-90 ℃, the temperature of tube bank condensed water has 130 ℃ of friends right, the temperature of pneumatic conveying drying condensed water has 130 ℃ of left and right, these a large amount of used heat are not utilized, and cause great waste.Tool statistics, the producer of current use pipe bundle drier dry wet material more than 9 0% does not have waste-heat recovery device, and its product of most of pipe bundle drier manufacturer is also without waste-heat recovery device.Although some pipe bundle driers producer adopts air-introduced machine forced heat-exchanging, device is recycled steam again, but because heat exchanger time is short, heat exchange effect is lower, and (the drained EGT scope after heat exchange is still higher, utilize overfire air fan to force to carry out the consumption that heat exchange has caused again electric energy, again cause the waste of the energy.And also need the corn steep liquor of soaking corn concentrate in producing the process of cornstarch, need heat, therefore how by both, in conjunction with reaching, effectively to utilize resource be a technology contents being badly in need of solution.
Summary of the invention
The purpose of this utility model, is exactly the problem existing for solving prior art, and has designed a kind of pipe bundle drier waste vapour recycle device, can make full use of waste heat and concentrate corn steep liquor, reaches energy-saving and cost-reducing object.
The technical solution of the utility model is: a kind of pipe bundle drier waste vapour recycle device, and this device includes indirect steam carrier pipe, heat exchanger, flash tank and cooling tank; In heat exchanger, be provided with steam-coil; The steam inlet of wherein said pipe bundle drier connects primary steam carrier pipe, steam (vapor) outlet connecting secondary steam pipeline, and described indirect steam carrier pipe connecting secondary heat exchanger, the steam outlet pipe of secondary heat exchanger connects cooling tank; The condensation-water drain of described pipe bundle drier connects flash tank, and the steam (vapor) outlet of described flash tank connects a heat exchanger, and the steam outlet pipe of a heat exchanger connects cooling tank.
A described heat exchanger and secondary heat exchanger are interconnected, and are communicated with corn steep liquor holding vessel.
In described flash tank, be provided with electric heater unit and pressure control device.
Pressure be set be 0.09 in described flash tank to 0.1Mpa.
After described cooling tank, connect condensed water holding vessel.
The utlity model has simple and reasonablely, easy to install, effectively reclaim indirect steam and high-temperature condensation water that pipe bundle drier is discharged, make full use of residual heat resources, improve the temperature that is heated liquid.The utility model, utilizing the tube bank secondary waste gas of pipe bundle drier generation and the heat of tube bank condensed water to corn steep liquor evaporation and concentration, can reduce 2/3 of evaporimeter primary steam consumption, has saved a large amount of energy, has increased the economic benefit of manufacturing enterprise.
