When the user system is running normally, condensate is discharged from the heat-using equipment, and is smoothly introduced into the flash tank through the special hydrophobic device, ****net device and other special hydrophobic devices. Secondary vapor separation can be utilized as needed. Separated condensate is introduced into the return tank by the heat pump, and the high-temperature condensate is directly sent to the boiler drum by the high-temperature water pump after the decarburization process. Back to the water tank level and pumps are automatically controlled, the basic realization of the boiler to produce as much steam can be back as much water water - steam balance (not taking into account the phenomenon of the system in the run, risk, drip, leakage phenomenon). The system will not produce oxygen corrosion, condensate will not be secondary pollution. The entire recovery rate process in a closed state operation.
The condensate recovery is a closed recovery method. In the recovery process, the equipment has been in a pressurized state, with high condensate recovery temperature, the heat is basically to achieve complete recovery. Because it is not in contact with the atmosphere, the condensate will not be contaminated, so that the amount of boiler discharge is greatly reduced, but also effectively prevent the generation of boiler scale.
1, the device replaces part of the heat manufacturers condensate open recovery. Open recovery that is, condensate generated by the heat equipment through the evacuator is discharged directly, the discharge of the vapor mixture is led directly to the cement pool or tin cans, and then add water to cool down to below 80 ℃, and then pumped to the boiler practice. This method can only recover part of the heat, about 30% to 50% of the emissions, and condensate in the recycling process in contact with the atmosphere, the impurities in the water increased dramatically, the loss of condensate (distilled water) of good quality.
2. In response to the heat consumption characteristics of each piece of equipment in the corrugated cardboard production line, the hydrophobic process has been reasonably reformed, and a special hydrophobic device designed by the Company has been adopted. The temperatures of the single-face machine and the hot plate have been improved at different speeds compared to those before the reform.
3, the recovery of condensate system adopts self-control frequency conversion technology, condensate directly back to the boiler drum. If the leakage of the system is not taken into account, the boiler steam balance can be realized, that is, the boiler produces as much steam as the water can be returned. And the return water temperature is high (up to 160 ℃), the boiler's steam pressure, steam temperature is guaranteed, thus improving the boiler's Ran burning conditions, enhance the boiler's ability to adapt to the coal.
