Technical field
The present invention relates to a kind of particle sampler of from the solid particle of piling up, taking a sample, more particularly, the present invention relates to a kind of sampler that is used for fixing the solid catalyst particle of bed bioreactor.
Background technology
In petrochemical unit, exist the fixed bed reactors of a large amount of filling solid catalysts.In the use of these reactors, owing to reasons such as catalyzer self performance or raw material condition or operation can cause catalyst performance decline and can not satisfy production requirement.Need to judge catalyzer performance at that time this moment, particularly for adiabatic reactor reactor commonly used, the bed temperature of its different producing depths is inequality, make catalyst deactivation speed difference to some extent, and when catalyst poisoning, its degree of intoxication of the catalyzer of different depth is also different, so need to judge the situation of different aspects catalyzer, just need carry out sample analysis to the catalyzer of different aspects.The way of in the past taking is that catalyzer is drawn out from the reactor top part layer.The disadvantage of this method is that for the bigger reactor of loadings, for example loadings is at the reactor more than 10 cubic metres, and workload is too big, and in the process that catalyzer is drawn out, causes the broken and loss of catalyzer easily.Therefore, when needs are taken a sample, only get the top layer of beds often and apart from the top layer more shallow place (general the degree of depth be no more than 20 centimetres), the state according to the analysis result of these samples being calculated integer catalyzer still, adopts the error of this method bigger.
" taking a sample to research of Catalyst in Platinum Group Metal Analysis ", metallurgical analysis 1998,18 (5) .25-28 adopt the sampling of pipe rifle sampler, this manages the thin-wall steel tube of rifle sampler with two kinds of specifications, be processed into telescopic sampling gun, diameter of inner pipe 2.5cm, tube wall mills into a flute profile according to the height of catalyst particle size and dress catalyzer metal bucket, the rifle head is taper, be about 3cm, be placed in the outer tube, the about 200cm of whole sampling gun.During sampling, sampling gun is firmly inserted till at the bottom of the bucket from the top of bucket, outer tube is extracted in segmentation then, whenever extracts one section outer tube, the interior pipe of rotatable and vibrations, the material of sampling point is entered in the tube seat, treat material charge in the mode of splendid attire material main body in behind the pipe, firmly depress outer tube, extract sampling gun, and then moving casing, the sample in making in the pipe flows out.
Chinese patent 94215878.4 disclosed a kind of rotary sleeve tubular type thief samplers comprise inner sleeve, outer tube, handle and tip; One longitudinal slot door is arranged on the inner sleeve, and groove Men Yiduan has an arc guide groove; The inner sleeve head is equipped with a tip, and afterbody has a handle; Also have longitudinal slot door on the outer tube, its width is greater than the width of inner sleeve, and the length of length and inner sleeve groove door is suitable; One end of outer tube has a rotation that is connected with outer tube to handle knob.During use, seal the inner sleeve longitudinal slot door, insert in the powder stock to be checked with outer tube, it is overlapping that the rotating jacket pipe makes both groove doors again, makes raw material enter inner sleeve, and then inner sleeve groove door is sealed, extract sampler out, can obtain the sample at each position in the raw material packet packaging container.
This technology can be suitable for for less reactor or container, but for industrial large-sized reactor, especially after catalyzer moves the long period, the resistance of beds is very big, often manpower can only insert about 1 meter, for total bed height of 3-4 rice, obviously not representative.And above technology is in order to reduce to insert resistance, and the diameter of sampler is all less, and this has also just limited the quantity of each taking-up sample.Judge that as the industrial reactor catalyst performance required sample size is more.The smaller sampling device just means increases the sampling number of times, reduce work efficiency.In addition, more than two kinds of technology can't accomplish to insert once, can finish serial sampling to each aspect catalyzer.
US 4958527 (1990) the disclosed sample cock assemblies that are used for the online sampling of particulate material, this sample cock assembly is installed on the sidewall of reactor, can carry out the online sampling of particulate material such as catalyzer.The sample cock assembly comprises valve body, valve body arm, electric plating propulsion, the mandrel that can move horizontally, stopple coupon, stopple coupon inserts in the interior beds of reactor, during sampling, catalyzer in the beds, both can take out by the flexible spiral organ in sample valve and the stopple coupon, also can extract out by vacuum system, at this moment, catalyzer enters the sample collection jar by stopple coupon and sample valve.The aspect of this sample cock assembly catalyzer sampling is fixed, and can not carry out the stratified sampling of catalyzer.
Technology truly has effect for particular reactor described in this patent, but in the industrial reactor design, all reactors all can not be reserved sampler.Even if sampler is installed in advance, this sampler also can only be got the catalyst sample of fixed position, place, and as fixed bed reactors, certain position that can't pre-estimate beds can go wrong, the position that needs sampling often at random, therefore pre-determine the sampler position, and be not suitable for most reactors.
