But unit 7 is connected, and the aftercooler 4 is connected by waterpipe with cooling unit 7, and the cooling unit 7 includes cooling column, cycle
Water pump.
As shown in Figure 1, the coating machine 1 is lithium battery even application spreading mass in nmp solvents, it is the forecooler 2, preceding
Cooler 3, aftercooler 4 cool down nmp exhaust gas, and nmp exhaust gas is filtered removal impurity by the filter 5, and the ventilation pipe 9 is for nmp
Each section in exhaust gas circulation recycling machine, the recovery room 6 recycles filtered nmp gases, and in actual moving process, nmp is useless
Gas is discharged by coating machine 1, is entered the air heat-exchange in forecooler 2, with Precooling unit 8 by ventilation pipe 9, is reached preliminary cooling
Effect, the air for the end that exchanges heat will not be discharged in air, but the other techniques produced via other pipeline flow-direction lithium batteries
In the process, the thermal energy of nmp exhaust gas is transferred in other technical process as carrier, nmp exhaust gas will also after forecooler 2
It exchanges heat by preceding cooler 3, aftercooler 4, but since its temperature is not high, the difficulty higher of heat energy utilization, therefore do not set device
Recycle this partial heat energy.
The utility model has the higher environment of part requirements of process temperature in view of the production of lithium battery, and utilizes precooler
Air of this part with thermal energy is used the thermal energy of the air trapping nmp recycling machine nmp exhaust gas of group 8, is other lithiums electricity
Pond production procedure provides the environment of higher temperatures, and compared with general n mp recycling machines, the utility model is utilized in nmp removal process
The thermal energy being difficult to be utilized, reduces the energy consumption of lithium battery production, while also improving the environment friendly of nmp recycling machines.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Any modification, equivalent replacement or improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
