PLC controlled organic waste gas treatment equipment

Abstract

The invention relates to PLC controlled organic waste gas treatment equipment. The equipment comprises: a dust removal system, a fan, a cooler, an adsorption system, a condenser, a stratification tankand 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, theinlet and outlet of the adsorption system are respectively connected to a cooler outlet and a condenser inlet, and the condenser outlet is connected to a stratification tank inlet. The PLC is connected to all executing agencies through a data bus. Gas containing organic waste gas enters the equipment through the inlet of the dust removal system, the dust removal system filters dust and impurity particles, the adsorption system adsorbs organic gas in the waste gas, and clean tail gas is directly exhausted, steam is utilized to desorb the adsorbed and saturated organic gas in the adsorption device, the desorbed organic gas is condensed by the condenser, and then the product flows into the stratification tank for standing, thus obtaining reusable 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 organic waste gas treatment equipment, in particular to a PLC-controlled organic waste gas treatment equipment. Background technique [0002] In the process of chemical production, a large amount of organic solvents are used, resulting in a large amount of waste gas containing organic solvent gas; the accumulation of waste gas exceeds the explosion limit, and there is a danger of explosion. If a large amount of organic waste gas is directly discharged into the atmosphere without treatment, it will pollute the environment and cause a waste of resources. The existing organic waste gas treatment generally adopts the direct condensation method of waste gas, the recovery efficiency of organic solvent gas is not high, and the current waste gas recovery and treatment equipment has high maintenance costs. To filter out the dust and particles, the filter element of the curr...

If a large amount of organic waste gas is directly discharged into the atmosphere without treatment, it will pollute the environment and cause a waste of resources

The existing organic waste gas treatment generally adopts the direct condensation method of waste gas, the recovery efficiency of organic solvent gas is not high, and the current waste gas recovery and treatment equipment has high maintenance costs. Filter and remove the dust and particles. The filter element of the current dust removal device has a short service life and is frequently replaced; dust clogging often occurs, and manual cleaning or replacement of the filter is required, which affects continuous production and efficiency and increases maintenance costs.
