Purification equipment capable of effectively treating dense smoke and dust

Abstract

The present invention relates to purification equipment capable of effectively treating dense smoke and dust. The purification equipment comprises a combustion chamber, a large particle dust removing chamber, water grooves, a flue, an induced fan and a purification chamber, wherein the bottoms of the combustion chamber, the large particle dust removing chamber and the purification chamber are provided with the water grooves, a funnel-shaped dry dust removing tank is arranged inside the large particle dust removing chamber, a water tank is arranged on the one purification chamber side corresponding to the flue, the top of the purification chamber is provided with a plurality of filtration screens, separation plates are arranged between the adjacent filtration screens and on the bottom of the purification chamber, both sides of the filtration screen are provided with a mist-like spraying port, and the purification chamber position on the far end of the flue is provided with a gas discharge channel. According to the present invention, the technical difficult problem that a lot of flue dust produced during filtration screen combustion can not be treated so as to cause adverse effects to the surrounding environment and produce heavy interference for normal production in the conventional plastic industry is overcome, and the dry dust removing and wet dust removing combined manner is adopted to completely filter the produced flue dust, wherein the purification rate can be more than 95%.

Description

technical field [0001] The invention belongs to the field of chemical engineering, and relates to waste gas treatment equipment, in particular to a purification equipment capable of effectively treating dense smoke and dust. Background technique [0002] Extruders and injection molding machines generally use filter screens as filter equipment, but due to the high temperature, the plastic that cokes on the screen cannot be cleaned; at present, the cleaning of the filter screen is widely used to clean the filter screen by burning high temperature to make it melt off, but because the plastic will be burned after burning A large amount of dense smoke and dust are produced. The dense smoke contains toluene when polystyrene is burned. A small amount of this substance can cause blindness, inhalation and vomiting. PVC combustion will also produce toxic hydrogen chloride gas; at the same time, in high temperature environments, It will lead to the decomposition of plastics into toxic ...

[0002] Extruders and injection molding machines generally use filter screens as filter equipment, but due to the high temperature, the plastic that cokes on the screen cannot be cleaned; at present, the cleaning of the filter screen is widely used to clean the filter screen by burning high temperature to make it melt off, but because the plastic will be burned after burning A large amount of dense smoke and dust are produced. The dense smoke contains toluene when polystyrene is burned. A small amount of this substance can cause blindness, inhalation and vomiting. PVC combustion will also produce toxic hydrogen chloride gas; at the same time, in high temperature environments, It will lead to the decomposition of plastics into toxic components, such as benzene rings, etc.; in addition, the full combustion of plastics will also produce a large amount of dust, and the discharged dust will have a disastrous impact on the environment. Production dust is the natural enemy of human health and is the cause of many diseases. main cause of disease
