High-pressure electrostatic purifier for heat-treatment smoke

Abstract

The utility model relates to a high-voltage electrostatic purification equipment used for purifying heat treatment fume, which belongs to the field of heat treatment environmental protection equipment. In the present invention, a high-voltage plate box and a guide cylinder are installed in the high-voltage electrostatic purification chamber, and an air outlet valve is installed on the top of the high-voltage electrostatic purification chamber; There is space for the coarse filter chamber and the gas mixing chamber to communicate with each other. Place a coarse filter in the coarse filter chamber; install an intake valve and an air mixing valve on the side of the air mixing chamber, set an oil collection tank at the bottom of the high-voltage electrostatic purification chamber and the coarse filter chamber, and install a rotating shaft and an explosion-proof plate on the box body. The sensors are respectively installed inside the high-voltage electrostatic purification chamber and the coarse filter chamber. The invention solves the problem that the oil fume filter screen is on fire, and at the same time solves the problem that the heat treatment oil fume has high temperature and is easy to cause fire and the safety problem caused by sudden gas explosion.

Description

technical field [0001] The invention relates to equipment in the technical field of environmental protection devices, in particular to a high-voltage electrostatic purification equipment for purifying oil fume from heat treatment. Background technique [0002] When the machined workpiece is heated in the heating furnace, there will be oily smoke overflowing from the heating furnace. When the heated workpiece is quenched into the oil, there will be an open flame and a large amount of oily smoke will overflow. After the oil-quenched workpiece is heated in the tempering furnace, there will be The oily fume overflows. These overflowing oily fumes are produced by heating the mechanical oil or quenching oil. The oily fume is composed of a mixture of aldehydes, ketones, hydrocarbons, fatty acids, aromatic compounds and heterocyclic compounds. The tiny particles of complex components can be suspended in the air for a long time, and the natural settling speed is small. These fumes wi...

Problems solved by technology

This type of electrostatic purifier does not consider the following problems in terms of structure: it does not consider the problem that the oil accumulated in the oil fume filter at the lower part of the electrostatic electrode arc will catch fire when it encounters a high-temperature object, and it does not consider that oil fume caused by high temperature heat treatment will cause oil fume to filter The problem of fire in the clean room or electrostatic clean room does not consider the safety problems caused by sudden gas explosion when the temperature, the ratio of oil fume gas to air content reaches a certain value
