Abstract
The utility model discloses an adding device for a catalytic agent used for determining sulphur contents of coal, which comprises a pipe body and a screen. The screen is arranged at the lower end of the pipe body, and the cross section of the pipe body is in a shape of a circle, a square or an oval. The adding device enables catalytic agent tungsten trioxide to be evenly added in a coal sample and evenly and sufficiently contacted with the catalytic agent tungsten trioxide and the coal sample, promotes the coal sample to be sufficiently burned, and leads measurement of the sulphur contents to be more accurate and stable. Furthermore, the adding device can easily control dosage of the catalytic agent tungsten trioxide and brings convenience in measurement work.
Description
Technical field
The utility model relates to a kind of instrument that is used to measure the coal sulfur content, particularly a kind of catalyzer adder.
Background technology
The measurement of coal sulfur content is an important process of weighing ature of coal.The GB/T214-2007 standard code in the coal mensuration of full sulphur three kinds of methods are arranged: Chinese mugwort formula block-regulations, coulometry, high-temp combustion neutralisation.Use tungstic acid to make catalyzer in the coulometric titration, coal sample is burnt under 1150 ℃ of conditions, the sulphur of various forms is oxidized to sulphuric dioxide and a small amount of sulfuric anhydride in the coal sample, the iodine and the bromine that generate with electrolysis potassium iodide-potassium bromide solution carry out titration to sulphuric dioxide, give birth to the electric weight that iodine or bromine are consumed according to electricity, calculate the content of full sulphur in the coal.
Catalyst tungstic oxide can impel the sulphur content in the sulfate to decompose fully under lower temperature (1150～1200 ℃), improves SO
2Production rate, improve the accuracy of measurement result.Generally when coal sample is measured,, can considerable influence be arranged to the sulphur measured value if the catalyst tungstic oxide distribution is in uneven thickness.Common method is that the medication spoon adds catalyst tungstic oxide in crucible, and this method is subjected to artificial factor bigger, catalyzer can occur and add situation such as inhomogeneous and influence measurement result, causes error.
The utility model content
The technical problems to be solved in the utility model provides a kind of catalyzer adder that can evenly add catalyst tungstic oxide in coulometric titration, improve coal sulfur determination degree of accuracy.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of catalyzer adder comprises body and screen cloth; Described screen cloth is positioned at the lower end of body.
The xsect of described body is circular, square or oval.
Adopt the technical progress that obtains after the technique scheme to be: when adopting Coulometric Titration coal sulfur content, the utility model can evenly be added into catalyst tungstic oxide in the coal sample, catalyst tungstic oxide is evenly fully contacted with the coal sample, promote the coal sample more fully to burn, make that the mensuration of sulfur content is accurate more and stable; And all right easily consumption of control catalyst tungstic acid of the utility model, for surveying work offers convenience.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Wherein, 1, body, 2, screen cloth.
Embodiment
By as can be known illustrated in figures 1 and 2: the catalyzer adder, comprise body 1 and screen cloth 2, described screen cloth 2 is positioned at the lower end of body 1, pastes between described screen cloth 2 and the body 1 to connect.The xsect of described body 1 is circular.
The inside surface of body 1 of the present utility model is smooth material, as stainless steel etc.
During use, catalyst tungstic oxide is packed in the body 1, screen cloth 2 is aimed at the container (porcelain boat or crucible) that fills the coal sample, and keep plumbness, screen cloth 2 areas as far as possible and the aperture area of measuring used container (porcelain boat or crucible) be consistent.When adding catalyzer, with the middle part that implements such as tweezers beat body 1 gently, like this, the catalyst tungstic oxide in the body 1 will be scattering on the coal sample uniformly, also can determine catalyst consumption according to circumstances.After using the utility model to add catalyzer in the coal sample, catalyzer can evenly distribute, and fully contacts with the coal sample, makes the coal sample fully burn, and improves the degree of accuracy of measuring, and also can grasp the addition of catalyzer according to actual conditions.
Claims (2)
1. a catalyzer adder is characterized in that comprising body (1) and screen cloth (2); Described screen cloth (2) is positioned at the lower end of body (1).
2. catalyzer adder according to claim 1, the xsect that it is characterized in that described body (1) is for circular, square or oval.
