SE-SLT Two-fluid Spraying System
I. Product Summary
The main function of this system is to automatically adjust the water consumption according to the temperature of gas in the kiln tail, making sure that the exit temperature is appropriate. When operating, the cooling water in the water tank goes through the filter, gets pressurized by the frequency converting pump, with its pressure and flow adjusted, then the water is sent through the pipe into the spray gun and becomes atomized particles due to the compressed air, vaporizing in the hot gas while absorbing large amount of heat, thus cooling and keeping the gas in a suitable temperature range. If the thermometer at the exit senses the gas temperature is higher than the set range, the frequency converting pump will automatically speed up under the control of PID, increasing the water flow and pressure, so that the temperature will come back to normal. If the temperature is lower than the set value, the pump will slow down, decreasing its pressure and flow, so that the gas temperature will go up into the set range. This system is widely applied in conditioning towers or humidifying pipes in the kiln tail of cement factories, in order to control the gas quality, lower its temperature and dust specific resistance so that electrostatic precipitators can function at the optimal level.
II. System Structure
The system consists of four parts:
1. Compressed air supply system, connected with compressed air source
2. Water supply and pressurization system, comprised of accessories including vertical multilevel centrifugal pump and delicate medium voltage valve, filter, pressure regulator and magnetic valve.
3. Atomization system on the top of conditioning tower or humidifying pipe, consisting of grouping control cabinet, annular pipe, spray gun, nozzle, high-pressure flexible tube, delicate valve and filter, etc.
4. Closed circuit multifunction control system, consisting of monitoring meter of air and water pressure, temperature and flow, low-voltage components, transducer, PLC and touchscreen.
