Abstract
A method of utilizing heat conduction oil to dry thiamine includes heat exchanging heat conduction oil with air and then leading heated air into fluidized bed to dry thiamine.
Description
Technical field
The present invention relates to a kind of sulphur ammonium drying means, be particularly suited for the process condition that has conduction oil circulation heating to produce in the coking industry.
Background technology
Domestic industrially drying technology mostly is the fluidized bed drying technology at present, mainly is by heat exchange cold air to be heated back feeding sulfuration bed step by step by heat transmission equipment to use the heated-air drying solid particle, obtains qualified products.And the coking industry range of application the widest be the sulphur ammonium drying bed of coke-oven plant, by hot blast moisture on the crystal in the fluid bed is taken away, obtain qualified ammonium sulfate products.
The hot blast that sulphur ammonium post fluid bed uses in the existing technology in general coke-oven plant is all by being produced the dry ammonia sulfate crystal of hot blast by Steam Heating by the cold air that air-introduced machine sucks, in the process of steam and cold air heat exchange, the steam use amount is big, easily produces a large amount of steam condensate (SC)s.And steam is the disposable use energy, and both uneconomical also not environmental protection can not recycle.However, this traditional mode of production is always the industry user.
Summary of the invention
In order to reduce the generation of steam condensate (SC), explore and realize the production technology and the target call of clean environment firendly more, the invention provides a kind of ammonium sulfate heat conductive oil drying method, stopped the generation of steam condensate (SC), reduced waste liquid amount; Realize saving energy and reduce the cost cleaner production.
Technical scheme of the present invention is that this kind ammonium sulfate heat conductive oil drying method is characterized in that, uses conduction oil and air heat exchange, the air feeding fluidized bed drying sulphur ammonium after the heating.
The invention has the beneficial effects as follows:
The present invention has broken through traditional mode of production, and it is very outstanding to save production cost, and environmental protection and economy does not have any waste liquid and produces, and meets the requirement of modern environmental protection and continuous development.
1), substitute steam heat-exchanging with conduction oil, the generation of having stopped steam condensate (SC) has reduced waste liquid amount.
2), conduction oil can recycle, realized energy-saving and cost-reducing, cleaner production.
Description of drawings
Figure is a process frame chart of the present invention.
The specific embodiment
As figure.The whole step of sulphur ammonium drying means is:
The sulphur ammonium crystal of discharging after the centrifuge blanking is delivered to vibrating fluid bed dryer by the spiral pusher machine, becomes hot-air with cold air after the fan heater heating and feeds fluid bed, and sulphur ammonium crystal is carried out drying.After the drying, after the cold wind cooling that air-cooler is sent into, enter sulphur ammonium hopper again.After the automatic weighing of packing machine, packing, send into warehouse for finished product from the sulphur ammonium crystal that sulphur ammonium hopper gets off.
The cold air heating is finished via fan heater.
The cold air heating technique is for to change conduction oil and cold air heat-shift into by Steam Heating, conduction oil oil-in and oil return opening are arranged on fan heater, cold air carries out heat exchange between fan heater and conduction oil, cold air is heated to set point of temperature enters drying bed, stopped the generation of steam condensate (SC), realize the recycling of thermal medium, promoted the development that clean energy-saving is produced.
The present invention is suitable for having the process condition of conduction oil circulation heating production.
