Fume emission on-line continuous detecting system sampling apparatus

Abstract

The invention discloses a sampling device for an on-line continuous detection system for flue gas discharge, which is characterized in that the sampling device is composed of a sampling and ash removal mechanism, a controller and a sampling pump. The sampling and dust removal mechanism is used to collect sample gas and remove dust in the gas, and is composed of a main structure, a backflush controller, a backflush air pipe, a cleaning controller, a flue gas sample gas outlet, a dust removal filter element, and a cleaning actuator. The controller is composed of a frequency converter, a microcomputer, a flue gas flow rate sampling interface, a control output interface, an output interface of the frequency converter, and a power supply wire interface. Synchronization of samples is achieved. The sampling pump is composed of a control line interface, a fan, a sample gas inlet for flue gas detection, and an outlet for excess sample gas. The invention solves the problems of sampling blockage, synchronous sampling and negative pressure sampling, and can be used for gas detection and sampling for controlling the production process in harsh environments, and is also suitable for environmental protection detection and sampling of various gases.

Description

technical field [0001] The invention belongs to the technical field of detection equipment, and in particular relates to a sampling device for an on-line continuous detection system of flue gas emission, which is applied to the detection of flue gas emission in industries such as metallurgy, cement, and thermal power generation. Background technique [0002] With the shortage of modern energy and the gradual entry of foreign enterprises into the Chinese market, our enterprises, especially some energy mining enterprises, must increase energy conservation and improve production efficiency. In order to optimize the production control of the industrial production process, it is necessary to select appropriate characterization quantities that can reflect the production reaction process. These characterization quantities may be the products of chemical reactions or the reaction conditions of reactions. For example, in the production process of metallurgy (alumina, iron ore roastin...
