Purification equipment and systems Due to the high environmental requirements of the purification equipment, we have focused on the problem of furnace purification. According to the airflow organization principle, the dust-containing flue gas enters the inertial purifying device and impacts on the baffle plate, so that the airflow is sharply turned, and the dust particles are separated by inertia, and the flue gas is forced to contact with a certain water film and water mist. The dust particles sink into the bottom of the water, and the cotton-like soot is collected and adsorbed on the water surface through the S-shaped channel and the fog-like water film area of ​​the water-blocking plate, so as to achieve the purpose of completely purifying the flue gas. In order to solve the problem of smoke short circuit, a three-stage intensive spray and spray system was introduced. The sewage is recycled after three stages of filtration to reduce secondary pollution. On the cleaning and purifying equipment, a hot water washing and steam purging device is provided to eliminate the oil stain on the inner wall of the purifying device.
When the purification equipment is running at low load, how to maintain the system with a certain pumping force, not only to ensure the normal operation of the stove, but also to ensure the purification effect of the equipment, through the feasibility study, and finally the design of the induction ventilation system, which guarantees the kitchen The load change of the stove is required to ensure the purification effect of the equipment.
In the process of manufacturing purification equipment, the gas-water separation device originally used the national standard water-blocking plate, but the installation was difficult and the maintenance was inconvenient. After research with the manufacturer, it was decided to assemble the plug-in structure, which is convenient for installation and easy to maintain. And cleaning up, proven by practice, the effect is good.
The electrical control system of the purification equipment: the furnace smoke purification equipment and the kitchen stove blowers of each floor are provided with electric interlocking devices and signal display. When the stove blower in any of the hotel's kitchens is started, the furnace purification system is automatically put into operation; when the stove blowers in all the kitchens of the hotel are stopped, the furnace purification system is stopped.
The characteristics of the flat 3 purification treatment system of the flue-cured purification equipment and the effect of the purification treatment system are composed of a clean room, an induced fan, a circulation and a pipeline. The system has full-automatic operation, no need for special personnel management, convenient operation and high purification efficiency.
The purification equipment is made of stainless steel with less failure and corrosion resistance. After a few years of use, the hotel has a good smoke purification effect.
Tested by the environmental monitoring station, the smoke concentration “Lingerman blackness†is less than one level, and the accumulated time of the exhaust gas concentration above two levels in one hour: the average value, the maximum value and the minimum value are all zero. In the outer wall of the main building, which is close to the flue gas discharge, about 8m, and the 40m long skirt swimming pool, there is no pollution effect and abnormal odor of the stove bird smoke, which fully meets the design requirements and national environmental emission standards.
Conclusion The purification equipment creates a new environmental protection technology to solve the low-level emission of kitchen smoke, and also opens up new channels for improving urban air pollution in the future, reducing the pollution of smoke and dust, protecting the environment and benefiting the society and future generations. The furnace flue gas purification equipment can not only be widely used in the purification of flue gas in the kitchen stove of the hotel, but also has broad prospects for fuel vapor and hot water boiler flue gas purification.
