A test device for detecting the comprehensive performance of denitrification catalyst and its application method

Abstract

The invention discloses a test device for detecting comprehensive performance of a denitration catalyst. The test device comprises a multi-path gas introduction device, a mixer, a heater, a reaction container, a measuring system, a data acquisition system, a control system and a reaction assisting reactor. The multi-path gas introduction device is used for mixing various gases introduced into the mixer. The heater is used for heating the gases mixed in the mixer. A heating device and a catalysis plate are arranged in the reaction container, and used for making the heated mixed gases react in the reaction container. The measuring system is used for detecting gas concentration, temperature and pressure data before and after the mixed gases are reacted. The data acquisition system is used for receiving and analyzing data transmitted by the measuring system. The control system is used for controlling work of the measuring system. The reaction assisting device is used for assisting implementation of reaction of the mixed gases. By means of the test device, components of the mixed gases can be conveniently controlled, various environment parameters of the catalyst are adjusted, and accordingly comprehensive performance testing of the denitration catalyst is achieved.

Description

technical field [0001] The invention relates to the field of environmental protection of thermal power plants, in particular to a test device for detecting the comprehensive performance of a denitrification catalyst suitable for thermal power plants and an application method thereof. Background technique [0002] As my country's main primary energy source, coal accounts for about 64% of primary energy consumption, while power plants, as large coal-burning households, account for about 47% of my country's coal output. Many pollutants such as nitrogen oxides (NO x ). [0003] Nitrogen oxides are one of the main pollutants that seriously endanger human health, and more than 95% of them are NO. With the rapid development of the economy, the coal-based energy structure has greatly increased the emission of coal-fired flue gas in my country, and NO x Pollution is becoming more and more serious, and has produced a series of problems, such as acid rain, photochemical smog, etc., ...

AI Technical Summary

Problems solved by technology

Since the simulation environments required by the above-mentioned different tests are different, if they are carried out separately, it will consume a lot of manpower and material resources, and it will be time-consuming and laborious. Therefore, it is necessary to develop a denitrification catalyst detection device with simple operation, low price and comprehensive detection performance.
