Description
Technical field
The utility model is specifically related to a kind of heat utilization system, particularly in a kind of high temperature solid state reaction of LiFePO 4, and the system that the heat of material behind the sintering is recycled.
Background technology
LiFePO 4, chemical formula are LiFePO
4, being called for short LFP, the positive electrode material for lithium battery recently newly developed is mainly used in dynamic lithium battery, uses as positive active material, and people's custom also is called LiFePO4.With traditional lithium ion secondary battery anode material, the LiMn of spinel structure
2O
4LiCoO with layer structure
2Compare LiMPO
4Raw material source more extensive, price is cheaper and non-environmental-pollution.
Present stage, the preparation method of LiFePO 4 is adopted high temperature solid-state method usually, namely raw material is carried out sintering and produce LiFePO 4.When the high temperature solid-state method synthesizing lithium ferrous phosphate; material need to be warming up to 700-800 ℃ of reaction; pass into simultaneously high pure nitrogen protection sintering process; after finishing, sintering needs with the way of chuck cold water circulation material to be chilled to room temperature; enter the cooling tower cooling after the cooling water heat exchange; a large amount of hot types toward atmosphere, is caused the loss of heat, and the normal temperature high pure nitrogen that passes into simultaneously is heated also can take away a large amount of heat.
Summary of the invention
The utility model provides a kind of atmosphere sintering furnace material heat recycling system, purpose is to solve the prior art problem, provide a kind of can be when material be cooled off, to material with the system that recycles of amount of heat, well reduced the loss of heat, simultaneously the heat that reclaims is re-used, reduced the waste of other energy.
The utility model technical scheme that adopts of dealing with problems is:
Atmosphere sintering furnace material heat recycling system, comprise the cooling section that links together with sintering furnace, cooling section is provided with cooling water jecket outward, and cooling water jecket is provided with water inlet and delivery port, described cooling section comprises air cooling section and water-cooled section, before the air cooling section places the water-cooled section; Be wound with coil pipe in air cooling section outer disk, coil pipe has air inlet and the gas outlet of sintering protection gas, and air inlet is positioned at air cooling section low-temperature space, and the gas outlet is positioned at air cooling section high-temperature region and communicates with sintering furnace inside; The water-cooled section is provided with cooling water jecket outward.
Described coil pipe divides three layers of interlaced arrangement, and the adjacent tubes spacing is 2mm.
Described coil pipe caliber is DN25*3mm, long 4500mm.
The beneficial effects of the utility model: heat recycling system of the present utility model comprises two cooling steps: air cooling and water-cooled.Owing to first the material behind the sintering is carried out air cooling, therefore in the material cooling, again protection gas is heated, make protection gas need not heat separately to enter and carry out atmosphere protection in the sintering furnace, saved electric energy.And protection gas is incorporated into the high-temperature region from low-temperature space, has adopted the mode of reverse flow heat exchange, and its heat exchange efficiency is greater than recuperation, can make the heat increase that displaces under the fixing heat exchange area.Another benefit of carrying out water-cooled after advanced promoting the circulation of qi is cold is when carrying out water-cooled, and the temperature of material reduces greatly, therefore can reduce the use of the water yield in Cooling Process, the water resource of saving.
Description of drawings
Fig. 1 is structural representation of the present utility model
Among the figure: 1. cooling section, 2. air cooling section, 3. water-cooled section, 4. coil pipe, 5. air inlet, 6. gas outlet, 7. cooling water jecket, 8. water inlet, 9. delivery port.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
For solving the problems of the prior art, the utility model adopts the material of nitrogen after to sintering pass into first atmosphere sintering furnace to cool off the method for cooling off by water-cooled again, in the cooling material, nitrogen is heated, the consumption that reduces cooling water reaches the purpose of material cooling, gas heating simultaneously, and the concrete structure of its system is as described below.
Atmosphere sintering furnace material heat recycling system as shown in fig. 1 comprises the cooling section 1 that links together with sintering furnace, and cooling section 1 comprises air cooling section 2 and water-cooled section 3, before air cooling section 2 places water-cooled section 3.Be wound with coil pipe 4 in air cooling section 2 outer disks, coil pipe 5 has air inlet 5 and the gas outlet 6 of protection gas, and air inlet 5 is positioned at air cooling section 2 low-temperature spaces, and gas outlet 6 is positioned at air cooling section 2 high-temperature regions and communicates with sintering furnace inside.Be provided with cooling water jecket 7 outside the water-cooled section 3, cooling water jecket 7 is provided with water inlet 8 and delivery port 9.
In order to make the water-cooled section have good heat transfer effect, 4 minutes three layers of interlaced arrangement of described coil pipe, adjacent tubes spacing are 2mm.Described coil pipe 4 calibers are DN25*3mm, long 4500mm.
When material cools off behind the sintering; material passes through air cooling section 2 and the water-cooled section 3 of cooling section 1 successively with conveyer belt; high pure nitrogen as protection gas enters coil pipe 4 from the air inlet 5 that is arranged in air cooling section low-temperature space, and the heat of material to nitrogen, carries out heat exchange by coil pipe 4 conduction.Along with nitrogen moves to gas outlet 6 directions that are positioned at air cooling section high-temperature region, the temperature of nitrogen raises.Because gas outlet 6 communicates with sintering furnace inside, the nitrogen after the intensification directly enters in the sintering furnace it is carried out atmosphere protection.Owing to absorbed heat the material of nitrogen behind sintering, therefore can heat to nitrogen separately again, saved electric energy.
After air cooling section 2, material enters water-cooled section 3, continues to cool off by the cooling water material.Because its temperature reduces greatly after the material process air cooling section 2, therefore can reduce the use of the water yield in Cooling Process, the water resource of saving.
Through the practical operation check, to room temperature, every day, loses heat 237000kJ/d reclaimed thermal device by installing air cooling additional, reclaimed heat 180000kJ/d with simple chuck water-cooling pattern cooling material, the rate of recovery 76%, and 50 degree are equivalent to economize on electricity every day.
