Description
Technical field
The utility model belongs to chemical technology field, relates to that a kind of it has broad applicability to desulfurizing agent Sulfur capacity determinator, can measure the multiple performance index of dissimilar desulfurizing agent.
Background technology
Desulfurizing agent refers generally to remove free sulphur in fuel, raw material or the unclassified stores or the medicament of sulphur compound.It is industrial that what be most widely used is ferric oxide desulfurizer, Zinc oxide desulfurizer, active carbon desulfurization agent etc.When selecting desulfurizing agent, the Sulfur capacity index of desulfurizing agent is most important selection foundation on the commercial production, and desulfurizing agent Sulfur capacity size has close contacting with assay method, therefore designs the rational desulfurizing agent Sulfur capacity determinator of a cover most important to closing.
At present, the Sulfur capacity determinator mainly contains with U-shaped pipe and detects penetrating Sulfur capacity and measuring the saturated Sulfur capacity of desulfurizing agent with gas making device of desulfurizing agent.
The segment that a small amount of (3g) desulfurizing agent of U-shaped pipe detection method is broken into 3 ~ 5mm off with the fingers and thumb is put into U-shaped pipe, and an amount of unginned cotton of taking off of packing into is held in U-shaped pipe ventilation, and the other end is put and detected reagent or test paper.Get 100ml check gas with eudiometer tube after the leak detection, with the flow of 10ml/min, allow gas pass through U-shaped pipe, until detect till reagent or the test paper variable color, and record consumes volume V, ml; Then calculate the Sulfur capacity that penetrates of desulfurizing agent according to following computing formula.
Thereby the defective of the method is to check density p and the coefficient of colligation F of gas to cause measurement result inaccurate by Accurate Determining.
Before namely testing, the saturated Sulfur capacity of measuring desulfurizing agent with gas making device weighs up first the quality m of sky desulfurizing agent post
1, a certain amount of desulfurizing agent is packed in the desulfurizing agent post, weigh up again its quality m
2Then connect experimental provision by requirement of experiment, begin experiment after the leak detection.Pass into abundant detection gas, the desulfurizing agent in to be desulfurization dose of post absorbs when saturated fully, stops experiment and takes off the desulfurization post and claim its quality to be designated as m
3Calculate the saturated Sulfur capacity of desulfurizing agent according to following computing formula.
The defective of the method is that minute is long, can not judge correctly many times whether desulfurizing agent has adsorbed saturated, therefore cause the result inaccurate; Need a large amount of detection gas in the mensuration process, experimental cost is high, and to detect gas be hypertoxicity gas, can produce larger harm to the experimenter is healthy.
As known from the above, also have a lot of defectives aspect the desulfurizing agent Sulfur capacity mensuration at present, determinator not only so that complex operation, measurement result are inaccurate, also has the device applicability not strong, can not measure different performance index with same device.
Summary of the invention
The utility model is for the defective that the above-mentioned background technology exists, provide a kind of operation more easy, measure accurately desulfurizing agent Sulfur capacity determinator.
A kind of mensuration desulfurizing agent Sulfur capacity new equipment comprises the compressed air source unit 1 that links to each other by the conduit order, assist gas device 2, U-shaped drying tube 5, desulfurizing agent post 11, tail gas absorption bottle 14.Described compressed air source unit 1 links to each other with a T shape grass tube 3, and a described T shape grass tube 3 endpiece link to each other with gas buffer bottle 4, described U-shaped drying tube 5 and the first mass flowmeter 6 successively by conduit; Described the first mass flowmeter 6 endpiece link to each other with 7 imports of the 2nd T shape grass tube, and the outlet of described the 2nd T shape grass tube 7 upper ends links to each other with the lower end of described desulfurizing agent post 11, and the upper end outlet of described desulfurizing agent post 11 links to each other with the second mass flowmeter 12.
Further, the outlet of the lower end of described the 2nd T shape grass tube 7 links to each other with detection ware 9, and the passage between them can be by spring clamp 8 controls; The passage that the upper end outlet of described the 2nd T shape grass tube 7 is connected with the lower end of described desulfurizing agent post 11 is by spring clamp 10 controls.
Further, the outlet of described the second mass flowmeter 12 links to each other with described tail gas surge flask 13, tail gas absorption bottle 14 successively by conduit.
Further, the lower end import of a described T shape grass tube 3 links to each other with described assist gas device 2 outlets.
In sum, the utility model is measured desulfurizing agent Sulfur capacity new equipment and had the following advantages: (1) the utility model has increased by a T shape grass tube 3, its lower end import links to each other with 2 outlets of assist gas device, can be according to the experiment needs, in experimental provision, pass into assist gas at reasonable time, make that experimental implementation is easy, the result is accurate.
(2) the utility model has increased the 2nd T shape grass tube 7, spring clamp 8, has detected ware 9 and spring clamp 10, can press from both sides 8 and the switch of spring clamp 10 by control spring, control the process of experiment, and check sulfurous gas by being placed on the variation that detects the Test paper color in the ware 9.
(3) the utility model has increased the first mass flowmeter 6 and the second mass flowmeter 12, and the mass rate that can directly read hydrogen sulfide gas makes the calculating of desulfurizing agent Sulfur capacity more easy, accurate.
