Abstract

The invention relates to a testing device and method capable of testing desulphurization and denitration performances of reactive coke simultaneously. The testing device comprises a test gas configuration system, a desulphurization and denitration reactor and a gas component detection system, the test gas configuration system comprises an ammonia gas supply pipeline, a first nitrogen supply pipeline, a NO supply pipeline, a SO2 supply pipeline, an oxygen supply pipeline, a gas mixer and a steam supply mechanism for mixing steam into the gas mixer, the gas mixer is connected with the desulphurization and denitration reactor via a mixed gas pipeline, and the mixed gas pipeline is provided with a pipeline heating unit arranged behind and used to heating the mixed gas pipeline to gasify water in the pipe. Via the device and method, the desulphurization and denitration performances of reactive coke can be tested in one test simultaneously, test time is shortened substantially, SO2 and nitrogen oxide in the gas are tested simulatensouly, engineering practicality is approached more, and the desulphurization and denitration performances of reactive coke are represented more accurately.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a test device capable of simultaneously testing the desulfurization and denitrification performance of active coke and a method for testing the desulfurization and denitrification performance of active coke by using the test device. Background technique [0002] Activated coke desulfurization and denitrification technology uses the adsorption and catalytic functions of activated coke to not only remove SO 2 It is a dry flue gas treatment technology that can simultaneously remove soot particles, mercury, dioxins, furans, heavy metals, volatile organic compounds and other trace elements in flue gas, and recover sulfur resources. This method has the advantages of simple process, low cost and resource utilization, and can avoid the series construction of purification devices caused by different pollutants in the flue gas. It is suitable for purifying sintering...

[0004] Chinese patent application CN200910113055.2 discloses a method and device for detecting the activity of a flue gas denitrification catalyst, which is aimed at the detection and evaluation of catalyst denitrification performance, and cannot detect the desulfurization performance of active coke; Chinese patent application CN201120299729.5 The disclosed flue gas purification multifunctional test device can test the performance of desulfurization, dust removal, denitrification, and heavy metal removal, but the test flue gas is generated by a coal-fired water heater, and the flue gas composition is unstable; Chinese patent application CN201410247416.3 discloses a Active coke desulfurization and denitrification performance characterization test method and its device, which proposes a device and method for separately testing and characterizing the desulfurization and denitrification performance of active coke, but in this patent, the desulfurization test and denitration test are carried out separately, and the test The flue gas composition does not contain nitrogen oxides during the desulfurization performance, and the flue gas composition does not contain SO2 when testing the denitrification performance. This is the same as the flue gas composition in the desulfurization and denitration process. 2 The actual situation that also contains nitrogen oxides does not match, and cannot accurately reflect the desulfurization and denitrification performance of activated coke, and testing the desulfurization and denitrification performance separately means that the test takes more time
