Detailed Description
The technical scheme of the utility model is further described in detail through the following specific embodiments.
As shown in fig. 1, a device for comparing the adsorption or catalytic degradation performance of smoke pollutants comprises a gas input pipeline 1, a comparison gas circuit pipeline 2, an actual reaction pipeline 3, a heating component, a detector 4 and an exhaust gas treatment unit 5.
The gas input pipeline 1 is respectively communicated with the inlet of the comparison gas circuit pipeline 2 and the inlet of the actual reaction pipeline 3 through the three-way switching valve 6, and the outlet of the comparison gas circuit pipeline 2 and the outlet of the actual reaction pipeline 3 are respectively communicated with the gas inlet of the detector 4.
And heating components are arranged outside the gas input pipeline 1, the comparison gas circuit pipeline 2 and the actual reaction pipeline 3.
Specifically, the heating component outside the gas input pipeline 1 is a first heating component 11, the first heating component 11 is a heating belt and a heat insulation layer which are wrapped outside the pipeline, wherein the heating belt is clung to the outer wall of the gas input pipeline 1, and the heat insulation layer wraps the heating belt and the gas input pipeline 1, so that the main purpose is to ensure that the gas components are transmitted at a certain set temperature, and avoid the premature condensation or other unknown changes of certain gas components. The actual reaction pipeline is internally provided with reactants, so that the gas can adsorb or catalytically degrade the set target components through the reactants.
The heating component outside the comparison gas circuit pipeline 2 is a second heating component 12, the second heating component 12 is a heating belt and a heat preservation layer which are wrapped outside the pipeline, and the structural principle is the same as that of the first heating component 11.
The heating element outside the actual reaction pipeline 3 is the third heating element 13, because the reactant is provided in the actual reaction pipeline 3, the area for placing the reactant is set as the reactor 7, the reactor 7 is a pipeline with unequal diameters, the reactor 7 is used for storing the reactant, and because the variety of the reactant is various, the required amount is also different, so the pipeline with unequal diameters is adopted, the determination can be made according to the usage amount of the reactant, and the design purpose is that: at the small pipe diameter, a small amount of reactants can have a preset gas circulation length, so that the requirement of reaction time is met; at large pipe diameters, a large amount of reactants can be compressed into a shorter gas flow length, preventing the length from being too long and excessively large in resistance.
Therefore, the third heating assembly 13 includes a heating belt and a heat-insulating layer disposed around the pipe portion, and a heating and heat-insulating chamber 14 disposed around the reaction area of the reactant, where the heating temperature in the heating and heat-insulating chamber 14 is adjustable, and specifically, an electric heating wire may be used to heat the environment by using radiation heating, and the diameter of the heating and heat-insulating chamber 14 is larger than that of the reactor 7.
The second half section of the comparison gas circuit pipeline 2 and the second half section of the actual reaction pipeline 3 are combined into a single output pipeline through a three-way valve 8, and the output pipeline is wrapped with a heating belt and a heat preservation layer, so that the temperature of gas entering the detector is kept constant.
The detector is a conventional instrument for analyzing the components of the smoke, can acquire the specific components of the smoke, and is characterized in that the residual substances after the analysis reaction are compared with all the components which are not reacted, so that the quantity of the missing components is acquired, and the adsorption or catalytic degradation effect of certain substances and reactants in the smoke can be known under the current condition.
In particular use, to achieve quantitative contrast, the flow rate of the gas input needs to be kept stable, and then quantified according to the time of gas flow, i.e., the time of test run.
The purpose of not using the flow control component is to avoid the change of the air pressure caused by the flow control component to the flue gas, wherein the temperature is increased and lowered, so that certain interference exists.
In determining the composition of the reactants, one may choose from the more common gas constituents such as carbon monoxide, nitrogen oxides (NO, NO2, total nitrogen oxides), formaldehyde, nicotine, 3-vinylpyridine, VOCs (benzene, toluene, xylenes, TVOCs) and the like.
The heating zones used in this example were all temperature controllable, and the heating could be turned off under certain conditions, depending on the conditions required for the test.
Finally, it should be noted that the above-mentioned embodiments are only for illustrating the technical scheme of the present utility model and are not limiting; while the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art will appreciate that: modifications may be made to the specific embodiments of the present utility model or equivalents may be substituted for part of the technical features thereof; without departing from the spirit of the utility model, it is intended to cover the scope of the utility model as claimed.
