Problems solved by technology

[0002] With the opening of the West-to-East Gas Transmission Project, there are more and more natural gas users, and combustion safety accidents also occur from time to time, which not only cause losses to equipment, but also greatly threaten personal safety
Detonation or explosion accidents caused by the failure of the automatic ignition system, explosion accidents caused by the lax closing of the electronic valve in the flameout protection system, accidents caused by the failure of the gas pressure level air pressure protection device or the failure of the device occurred repeatedly in different enterprises
At the same time, one gas furnace cannot supply heat to multiple sections at different temperatures, which increases the degree of repetition of the equipment
[0003] The flash device uses a gas furnace for direct heating, causing secondary pollution of semi-finished products
The water in the tail gas of natural gas will make the material absorb water, so that the drying and dehydration (attached water, crystal water) effect of the material will be reduced. explosion hazard
[0004] The activation device uses a gas furnace for direct heating, causing secondary pollution of semi-finished products
The water in the tail gas of natural gas will make the material absorb water, so that the drying and dehydration (attached water, crystal water) effect of the material will be reduced. explosion hazard
The manual control of feeding in the activation furnace leads to unstable product quality and increases the cost of finished products

Embodiment Construction

[0053] The following is an example of an activated alumina ball production plant with an annual output of 10,000 tons.

[0054] First, purchase or process the relevant parts of each device according to the production design, and then carry out equipment. After the equipment is ready, process according to the following operation process.

[0055] Put the aluminum hydroxide raw material into the raw material bin 29 first, and then evenly transport it into the micropowder mill 32 by the tubular screw conveyor 30. , under the traction of the high-pressure induced draft fan 34, it passes through the powder classifier 31 and enters the dust collector 27 (the raw material with a particle size that does not meet the standard cannot pass through the powder selection mechanism), and the raw material with a particle size that meets the standard passes through a special structure in the settling chamber of the dust collector. Raw material and gas are separated and deposited in the settling...

The producing device has a good popularization value and a good practical value, and after the producing device is widely popularized and applied, favorable economic benefits and social benefits can be generated.

Description

technical field [0001] The invention relates to a device and a process for processing alumina, in particular to a process and a device for producing and processing activated alumina from alumina. Background technique [0002] With the opening of the West-to-East Gas Transmission Project, there are more and more natural gas users, and combustion safety accidents also occur from time to time, which not only cause losses to equipment, but also greatly threaten personal safety. Detonation or explosion accidents caused by the failure of the automatic ignition system, explosion accidents caused by the lax closing of the electronic valve in the flameout protection system, and accidents caused by the lack of gas pressure level air pressure protection device or device failure occurred repeatedly in different enterprises. At the same time, one gas furnace cannot supply heat to multiple sections at different temperatures, which increases the degree of repetition of the equipment. [0...
