Abstract

The invention discloses an apparatus for measuring dust content of flue gas and a method thereof. The apparatus comprises a dust collecting device, a sampling device and a suction device; an outlet end of the dust collecting device is connected with an inlet end of the sampling device, and the outlet end of the sampling device is connected with the inlet end of the suction device; in the method, the flue gas passes the dust collecting device under the condition of constant speed suction, the dust in the flue gas is filtered by filter paper, and the dust content of the flue gas is calculated by weighing the weight of the filter paper before filtering the dust and the weight of the filter paper after filtering the dust and putting the weights into a formula. By the device for measuring the dust content of the flue gas, the dust content of the flue gas can be accurately analyzed. The device has the advantages of novel design, simple structure and easy implementation, and is very applicable to large scale popularization and use. The method for measuring the dust content of the flue gas has the advantages of safe and reliable sampling, simple operation, accurate and reliable analysis result and fast detection.

Description

technical field [0001] The invention relates to the detection field of substances in flue gas, in particular to a device and method for measuring dust content in flue gas. Background technique [0002] A large amount of dust will be generated during the desulfurization process, which will affect the environmental safety, the service life of the equipment and the health of the operators. Industrial dust can cause workers to suffer from various occupational diseases that are difficult to cure. Excessive dust can also cause environmental pollution, affect people's normal life and work, and induce human respiratory diseases. [0003] Excessive dust can also affect the flue gas desulfurization system. During the desulfurization process, if a large amount of dust in the flue gas enters the absorption tower and mixes with the limestone and gypsum slurry in the tower, it will hinder the absorption of SO by the limestone slurry. 2 The absorption of Ca in limestone reduces the 2 +...
