Embodiment

[0018] Example: such as figure 1 As shown, a precision casting roasting furnace flue purification system includes a furnace 1, the exhaust pipe 2 of the furnace 1 is connected to a cooling tower 3, and the cooling tower 3 is connected to a bag type dust collector 4, and the bag type dust collector The device 4 is connected with a water film deduster 5 again, and the side of the water film deduster 5 is also connected with a chilled water unit 6. The water film dust collector 5 is connected with an electrostatic precipitator 7, and the electrostatic precipitator 7 is connected with a UV photolysis air cleaner 8, and the UV photolysis air cleaner 8 is finally connected with a high-altitude chimney 9.

[0019] Use: In the present invention, the waxy smoke in the kiln is first sent to the cooling tower for cooling. Then use the bag filter to filter out the large and specific dust in the smoke, and filter out the finer dust in the smoke. Followed by the water film dust collector ...

Abstract

The invention discloses a flue purification system for a precision casting roasting furnace. The flue purification system comprises a furnace, wherein smoke with wax in the furnace is fed into a cooling tower to be cooled, and then dust with large particles and high specific gravity in the smoke can be filtered by a bag filter, and fine dust in the smoke can also be filtered. The dust removal effect is further improved by a water dust scrubber. Certainly, a more important effect of the water dust scrubber is to cool the smoke again, so a chilling unit needs to be added; and therefore, the ratio of water vapor in the smoke is greatly decreased so as to serve a subsequent electrostatic precipitator. If excessive water vapor exists, the electrostatic precipitator cannot normally achieve effects, so addition of the chilling unit is very necessary. Then, the smoke is ionized by the electrostatic precipitator by utilizing a high voltage electric field, and dust charge in airflow is separatedfrom the airflow under the action of the electric field. Finally, malodorous gases are split by a UV photolysis air purifier. Therefore, the gas can be safely discharged to the atmosphere.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a flue purification system of a precision casting roasting furnace and kiln. Background technique [0002] Wax discharge kiln is widely used in industrial sintered products, but its obvious defect is serious environmental pollution, which mainly comes from the random discharge of smoke. Therefore, the relevant national departments have issued the "Emission Standard of Air Pollutants for Industrial Furnaces" (GB9078- 1996) to limit the behavior of enterprises without environmental awareness. [0003] However, there are also companies that are very attentive and focus on solving the problem of smoke emission from the wax discharge kiln. Among them, the invention patent CN201510124951.4 of an enterprise in Hunan discloses a wax discharge smoke treatment furnace. The wax discharge smoke treatment furnace includes a furnace body, a spray The fire assembly...
