Concentration gas distributing device and concentration gas distributing method for organic waste gas

Abstract

The invention discloses a concentration gas distributing device and a concentration gas distributing method for an organic waste gas. The concentration gas distributing device comprises a gas distributing tank, a variable-frequency air blower and a PLC (programmable logic controller), wherein a solvent chamber and a heating chamber which are transversely formed are formed in the gas distributing tank; a metering pump for pumping a solvent into the heating chamber is arranged in the solvent chamber; an electric heater is arranged in the heating chamber; a gas outlet tube is arranged on the heating chamber; a concentration detecting device is arranged on the gas outlet tube; an air outlet of the variable-frequency air blower extends into the heating chamber; the PLC is used for regulating the rotation speed of the metering pump, the temperature of the electric heater and the air quantity of the variable-frequency air blower according to the detected results of the concentration detecting device. The concentration gas distributing device controls the temperature of an intelligent heater through a PLC system to replace a conventional bubble heating mode, is small in size, quick to heat up and strong in universality, avoids excessive concentration fluctuation of an organic solvent with a high boiling point under a constant-temperature water heating condition, overcomes problems of low distributed gas amount and inapplicability to a continuous small test or a pilot test, and can automatically demarcate different mass concentration curves according to the needs.

Description

technical field [0001] The invention relates to a gas distribution device, in particular to a concentration gas distribution device and a gas distribution method for organic waste gas. Background technique [0002] The gas distribution device is mainly aimed at the simulated gas composition required in the laboratory and various environments. The mixing output device is set by itself according to the ratio. The main core component is the mass flow controller. Using its high precision and high accuracy, it can precisely control the input volume of each gas component. After the professionally designed and produced gas mixing chamber output. [0003] Due to the existing organic waste gas treatment equipment, not all organic waste gas has corresponding engineering cases, and before engineering design, there must be sufficient small test data or pilot test data as a basis. The existing gas distribution devices for bubbling heating in constant temperature waters and experimental...
