Technical field
The present invention relates to a kind of device that can effectively utilize Aluminium hydroxide roasting stove liquid bed water cooler waste heat, belong to Aluminium hydroxide roasting heat energy reutilization technology field.
Background technology
At present, in the aluminum oxide industry production system, stoving oven is as last procedure in the Production Flow Chart, and white lake carries out roasting at this and removes crystal water wherein and form final sand-like aluminum oxide finished product (AL2O3).
Sand-like aluminum oxide powder temperature after the roasting is 270 ℃～320 ℃, can be delivered to aluminum oxide warehouse and packing outward transport in the time of need in stoving oven liquid bed water cooler, being cooled to below 80 ℃.Traditional way is to build a recirculated water station for stoving oven specially; With common service water is medium; Circulation refrigerating industry water carries out heat exchange and aluminum oxide powder is cooled to temperature required with the sand-like aluminum oxide powder of pyritous after getting into stove liquid bed water cooler; Return cooling tower after the heat absorption of circulation refrigerating industry water heats up and cool, so repeatedly circulation.This type of cooling is not only underused high temperature oxidation aluminium powder waste heat, causes energy dissipation, has also increased the infrastructure investment and the operation and maintenance cost of stoving oven system.
Summary of the invention
The technical problem that the present invention will solve provides and a kind ofly can make full use of high temperature oxidation aluminium powder waste heat, save energy, reduces the device that can effectively utilize Aluminium hydroxide roasting stove liquid bed water cooler waste heat of cooling Infrastructure, to overcome the deficiency of prior art.
The technical scheme that the present invention adopts is: it comprises stoving oven liquid bed water cooler, heat power plant's desalted water station and heat power plant's power house; On heat power plant's desalted water station, be connected with the desalination water inlet pipe; The other end of desalination water inlet pipe is connected with the water-in of stoving oven liquid bed water cooler; On the water outlet of stoving oven liquid bed water cooler, be connected with the desalination rising pipe, the desalination rising pipe is connected with water system in the heat power plant power house.
On the desalination water inlet pipe, be provided with valve.
On the desalination rising pipe, be provided with valve.
The leaving water temperature(LWT) of desalination rising pipe is 70～80 ℃.
Compared with prior art; Owing in aluminum oxide industry is produced, need auxiliary construction heat power plant, the present invention intends and adopts heat power plant's de-mineralized water to replace the general industry water in the traditional technology, and de-mineralized water is to be used by boiler of feeding after the steam heating under the normal circumstances; In native system; Return heat power plant's boiler of feeding after de-mineralized water absorbs heat and heats up and use in the liquid bed water cooler,, and can produce regulation and control owing to heat power plant runs without interruption throughout the year.Through adopting said system; Available heat power plant de-mineralized water replaces the general industry water in the traditional technology, has not only made full use of the waste heat of high temperature oxidation aluminium powder, has improved utilization rate of waste heat in the production; Reduced and under normal circumstances needed energy consumption that the de-mineralized water heat temperature raising is brought; Also reduce the infrastructure investment of stoving oven production system, reduced the expense of liquid bed water cooler running maintenance, had remarkable social benefit and economic benefit.
