PLC controlled dust and organic waste gas treatment equipment

Abstract

The invention relates to PLC controlled dust and organic waste gas treatment equipment. The equipment comprises a dust removal system, a fan, a cooler, an adsorption system, a condenser, a stratification tank and a PLC. The inlet and outlet of the dust removal system are respectively connected to a dust and organic waste gas inlet and a fan inlet, a fan outlet pipe is connected to a cooler inlet pipe, the inlet and outlet of the adsorption system are respectively connected to a cooler outlet and a condenser inlet, the condenser outlet is connected to a stratification tank inlet, the PLC is connected to all executing agencies through a data bus, dust and organic waste gas enter the equipment through a dust removal system inlet, the dust removal system filters dust and impurity particles, the adsorption system adsorbs organic gas in the waste gas, and the clean tail gas is discharged from an emptying valve of the adsorption system, steam is utilized to desorb the adsorbed and saturated organic gas, and after condensation by the condenser, the product then flows into the stratification tank for standing, thus obtaining a clean organic solvent. The equipment can achieve continuous, automatic and safe operation, and is maintenance-free and cost-saving.

Description

technical field [0001] The invention belongs to the technical field of solvent recovery, and mainly relates to a dust and organic waste gas treatment equipment, in particular to a PLC-controlled dust and organic waste gas treatment equipment. Background technique [0002] In the process of chemical production, especially in the production of modeling powder, a large amount of organic solvents are required to generate a large amount of waste gas containing organic solvent gases; at the same time, a certain amount of dangerous and explosive metal dust, such as aluminum These dusts may explode under certain conditions and bring safety hazards; if a large amount of organic waste gas is directly discharged into the atmosphere without treatment, it will pollute the environment and waste resources. The existing organic waste gas treatment generally adopts the direct condensation method of waste gas, and the recovery efficiency of organic gas is not high; the existing dust collectio...

[0002] In the process of chemical production, especially in the production of modeling powder, a large amount of organic solvents are required to generate a large amount of waste gas containing organic solvent gases; at the same time, a certain amount of dangerous and explosive metal dust, such as aluminum These dusts may explode under certain conditions and bring safety hazards; if a large amount of organic waste gas is directly discharged into the atmosphere without treatment, it will pollute the environment and waste resources

The existing organic waste gas treatment generally adopts the direct condensation method of waste gas, and the recovery efficiency of organic gas is not high; the existing dust collection and filtration device has a short service life, and dust clogging often occurs, requiring manual cleaning or replacement of the filter screen. Affects continuous production and efficiency; in the process of molding powder production, it is necessary to treat hazardous dust and organic waste gas at the same time, and the equipment that can treat dust and organic waste gas at the same time is not yet mature
