Abstract

The invention discloses a device for synchronously sampling condensable particles and sulfur trioxide in coal-fired flue gas and a working method of the device, and belongs to the field of industrialwaste gas purification environmental protection and energy. The invention aims to solve the problem that the existing equipment is difficult to effectively measure the actual condensable particle concentration of coal-fired flue gas discharged into the atmosphere and distinguish the main component sulfur trioxide of the coal-fired flue gas. According to the invention, the mixing process of the flue gas discharged into the atmosphere is simulated by controlling the temperature, pressure, humidity and other parameters of the flue gas and diluted air, and the condensable particles in the mixed gas is collected; meanwhile, the sulfur trioxide condensing devices are arranged in parallel, so the sampling of sulfur trioxide in the sampled flue gas is considered, and the condensable particles andsulfur trioxide are synchronously measured, so that the actual discharge condition of coal-fired flue gas pollutants can be analyzed, the accurate regulation and control are performed, and it is ensured that the discharge of the pollutants meets the discharge requirement.

Description

technical field [0001] The invention belongs to the fields of industrial waste gas purification, environmental protection and energy, and in particular relates to a synchronous sampling device for condensable particulate matter and sulfur trioxide in coal-fired flue gas and a working method thereof. Background technique [0002] my country's coal-based energy structure will not change for a long time. Therefore, controlling the emission of coal-fired flue gas pollutants is an important task for my country's air pollution control. In recent years, coal-fired power plants have promoted large-scale ultra-low emission transformation work, SO 2 The discharge of conventional pollutants such as , NOx and soot has been effectively controlled. On the other hand, the main components of condensable particulate matter are inorganic components such as sulfur trioxide and metal ions, and organic components such as polycyclic aromatic hydrocarbons. They mainly exist in the form of gaseous...
