Abstract
The utility model discloses a device capable of effectively utilizing waste heat of an aluminum hydroxide calcinatory fluidized bed cooler, which comprises a calcinatory fluidized bed cooler (1), a thermal power plant desalted water station (2) and a thermal power plant main power house (3), wherein the thermal power plant desalted water station (2) is connected with a desalted water inlet pipe (4); the other end of the desalted water inlet pipe (4) is connected with the water inlet of the calcinatory fluidized bed cooler (1); the water outlet of the calcinatory fluidized bed cooler (1) is connected with a desalted water outlet pipe (5); and the desalted water outlet pipe (5) is connected with a water system in the thermal power plant main power house (3). In the utility model, thermal power plant desalted water can be utilized to replace common industrial water in the traditional process, and thus, the waste heat of a high-temperature alumina powder fully utilized, the waste heat use ratio in the production is improved and the energy consumption brought by the reason that the desalted water needs to be heated up under the normal condition is reduced and the infrastructural investment of a calcinatory production system is also reduced. The device has obvious social benefits and economic benefits.
Description
Technical field
The utility model relates to a kind of device that can effectively utilize Aluminium hydroxide roasting stove ebullated bed water cooler waste heat, belongs 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 aluminium hydroxide 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 being cooled to below 80 ℃ in stoving oven ebullated bed water cooler.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 entering stove ebullated 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 problems to be solved in the utility model provides and a kind ofly can make full use of high temperature oxidation aluminium powder waste heat, the device that can effectively utilize Aluminium hydroxide roasting stove ebullated bed water cooler waste heat of save energy, minimizing cooling Infrastructure is to overcome the deficiencies in the prior art.
The technical solution adopted in the utility model is: it comprises stoving oven ebullated 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 ebullated bed water cooler, be connected with the desalination rising pipe on the water outlet of stoving oven ebullated bed water cooler, 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 utility model intends adopting the general industry water in heat power plant's de-mineralized water replacement traditional technology, 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 ebullated bed water cooler,, and can produce regulation and control owing to heat power plant runs without interruption throughout the year.By adopting said system, available heat power plant de-mineralized water replaces the general industry water in the traditional technology, not only made full use of the waste heat of high temperature oxidation aluminium powder, improved utilization rate of waste heat in the production, reduced the energy consumption that under normal circumstances the de-mineralized water heat temperature raising need be brought, also reduce the infrastructure investment of stoving oven production system, reduced the expense of ebullated bed water cooler running maintenance, had remarkable social benefit and economic benefit.
