Description
The utility model relates to a kind of multiple function apparatus of measuring various solid granular object character, especially measure the instrument of catalyzer and carrier character, particularly measure the instrument of catalyzer and carrier water absorptivity, bulk density and filling voidage.
In scientific research, production practices and daily life, we often need measure the character such as bulk density, water absorptivity of various solid granular objects.With the catalyzer is example, and what the water absorptivity of catalyzer reflected is the size of catalyzer duct internal volume.When the preparation catalyzer, measure the water absorptivity of catalyzer, say so accurately and measure the amount of adsorption activity component solution, be the data that the immersion process for preparing catalyzer is necessarily required.Test the water absorptivity of indoor measurement catalyzer now, normally the catalyzer with certain mass is soaked in the water, make it fully saturated after, more remaining water filtration is gone out, according to the volume of institute's consume water, thereby try to achieve the water absorptivity of catalyzer.But this method easily makes the moisture content volatilization because specimen in use is few and the running time is longer, thereby makes the water absorptivity of the catalyzer that records inaccurate.The bulk density of catalyzer is meant the quality of unit volume inner catalyst (or carrier).Bulk density is relevant with multiple factors such as the character of shape, carrier of catalyzer own and active component contents, and it is one of significant data of weighing the catalyst technology index.At present, the bulk density of experiment indoor measurement catalyzer, adopted is the graduated cylinder method more.With the bulk density of graduated cylinder method mensuration catalyzer, at first catalyzer to be packed in the graduated cylinder, artificial makes it do horizontal and vertical motion in graduated cylinder, so that it loads in graduated cylinder is closely knit, and because everyone operation difference, therefore, the artificial accidental error that causes also can be far from each other.If can eliminate or this accidental error is converted into the systematic error of instrument with will the be this artificial accidental error of a kind of instrument, the accuracy of catalyst buildup density is further improved, the industry amplification of following catalyzer is significant.Voidage is meant that then the volume that is not occupied by catalyzer in the reactor accounts for the long-pending ratio of overall reactor.It also is one of important technology index of catalyzer.At present, the voidage of experiment indoor measurement catalyzer normally adopts mercury intrusion method to record.Though the numeric ratio that this method records is more accurate, because this method more complicated, the cycle that obtains data is longer, and therefore mercury healthy also harmful to the people simultaneously be difficult in the laboratory and catalyst manufacturer is promoted the use of.
