Embodiment 1

[0028] Example 1: SO 2 Exhaust gas adsorption teaching experiment.

[0029] A university carried out experimental teaching of waste gas adsorption and purification. The content of the experiment was to measure the adsorption of SO by activated carbon in a fixed bed. 2 Simulate the breakthrough curve of exhaust gas to compare the adsorption effect of modified and unmodified activated carbon. When using a conventional adsorption experiment device, generally each device is equipped with 4 adsorption columns, the laboratory needs to purchase at least 4 sets of the same device, and configure 4 gas sources (gas cylinders) and at least 8 to 10 A gas composition detection instrument. To complete the experiment in a class of 32 students, in order to ensure that everyone participates in the operation, the students in the class need to be divided into two groups to conduct the experiment in turn. After the first batch of students completed the breakthrough curve test of unmodified act...

Embodiment 2

[0032] Example 2: The catalytic oxidation catalyst of NO exhaust gas is preferably developed.

[0033] Still taking the configuration of the above device as an example to describe the research process and effect of carrying out the NO exhaust gas oxidation catalyst screening activity test, and then optimizing the catalyst formulation.

[0034] A feasible technical route for smoke / exhaust gas denitrification is to partially oxidize NO into NO 2 , and then absorb and purify it with the help of wet desulfurization and denitrification equipment. Since the oxidation process of NO is very slow under low temperature and low concentration conditions, the key to this technical route is to develop efficient catalytic oxidation materials. During the research and development process, it is planned to use the impregnation method to test the catalytic activity of materials loaded with metal oxide active components on different supports.

[0035] Firstly, six kinds of metal oxides were loa...

Abstract

The invention discloses a multifunctional experimental device for purifying gaseous pollutants. A gas distribution system comprises a simulation gas source, a flow meter, a mixing tank, a gas flow distributor and a flow meter of the gas flow distributor; a parallel reaction system comprises a plurality of reactor assemblies detachably mounted on a support base, each reactor assembly comprises a sleeve and a plurality of reactor elements detachably mounted in the sleeve, and a gas inlet pipeline of each reactor element is detachably connected with the tail end of the gas flow distributor and the tail end of the flow meter of the gas flow distributor separately; a purging regeneration system comprises a gas heating tank, and the gas heating tank is connected with purging gas and connected with the front end of the gas flow distributor and the front end of the flow meter of the gas flow distributor through gas source branch circuits; a detection and monitoring system comprises a pressuregauge, a temperature probe, a matched temperature display instrument, a matched heating controller and a gas component monitor. The multifunctional experimental device is simple in structure and flexible and convenient to operate and solves the problems that existing gas adsorption or catalytic purification experimental devices have few air paths and are large in workload, inconvenient to assemble, disassemble and operate, not ideal in temperature control and the like.

Description

technical field [0001] The invention belongs to the technical field of gas-solid test devices, and in particular relates to a multifunctional test device for purifying gaseous pollutants. Background technique [0002] With the continuous growth of industrial development and energy consumption, the problem of air pollution has become increasingly serious, which has attracted widespread attention from all walks of life. my country's air pollutants mainly come from the production process of thermal power, non-ferrous smelting, petrochemical, chemical, coating, pharmaceutical, coking and other industries and automobile exhaust. The exhaust gas components include nitrogen oxides (NO X ), sulfur dioxide (SO 2 ), CO, NH 3 、H 2 S, heavy metals and volatile organic pollutants (VOCs), etc. Gaseous pollutants are large in quantity, wide in scope, and complex in composition, all of which are toxic to a certain extent. Direct discharge will have a serious impact on the atmospheric en...
