Tail gas treatment device for reducing Vocs in tail gas of pesticide production workshop

Abstract

The invention discloses a tail gas treatment device for reducing pesticide production workshop tail gas Vocs, and relates to the technical field of waste gas treatment equipment.The tail gas treatment device comprises a pretreatment assembly, a concentration assembly and an absorption assembly, and the pretreatment assembly, the concentration assembly and the absorption assembly are connected in an end-to-end mode through pipelines to form a complete passage; waste gas firstly passes through the pretreatment assembly to be subjected to dust removal and impurity removal, the concentration assembly comprises a condensation box and a sub-rotating device, the sub-rotating device is rotationally arranged in the condensation box, the condensation box is provided with a pressurization pipe and a discharge pipe, and the pressurization pipe and the discharge pipe are connected with the sub-rotating device through a sealing connection mechanism. The motor is provided with a pressurizing mechanism used for driving the pressurizing pipe to pressurize and an intermittent rotating mechanism used for driving the sub-rotating device to change positions. The device can pressurize the tail gas in batches when the tail gas passes through the device, so that the gas concentration of Vocs is improved in a low-temperature and high-pressure environment, and the Vocs can be conveniently adsorbed and removed.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment equipment, in particular to a tail gas treatment device for reducing the tail gas Vocs of a pesticide production workshop. Background technique [0002] Vocs (volatile organic compounds) are volatile organic compounds, which refer to organic compounds with saturated vapor pressure greater than 70.91Pa at normal temperature, boiling point below 50-260°C at standard atmospheric pressure of 101.3kPa and initial boiling point equal to 250°C, or organic compounds at normal temperature and pressure Any volatile organic solid or liquid. [0003] Condensation method is a relatively common method for removing Vocs. Condensation method uses the property that substances have different saturated vapor pressures at different temperatures to condense pollutants in vapor state and separate them from exhaust gas. In the prior art, condensers are generally used to The waste gas is cooled, and the trea...
