Abstract
The utility model relates to a high-purity ethylene preparation device and in particular relates to a large device for producing high-purity ethylene through chromatography, which is suitable for chemical synthesis of ethylene. The large device for producing high-purity ethylene through chromatography is composed of the following mutually connected components: a raw material storage tank is connected with a sample injector through a pipeline and is connected with the inlet of a separating column, and the outlet of the separating column is serially connected with a first cold trap and a second cold trap through a connecting pipeline. The device is an ideal high-purity ethylene preparation device with reasonable design and convenience for use.
Description
Technical field
The utility model relates to the device of high-purity ethylene preparation facilities, particularly a kind of producing high-purity ethylene by large-scale chromatography, is suitable for the chemical industry synthesizing ethylene.
Background technology
At present, high-purity ethylene is of many uses, is widely used as standard gas, in-line meter standard gas, calibrating gas, prepares some extraordinary gas mixture in fields such as industrial sectors such as metallurgy, electronics, chemical industry, oil and fundamental research, air monitoring, aviation, nuclear power.But technology of preparing is not perfect, poor product quality, and problem is many, can only be for the manufacture of the product of low specification.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of device of producing high-purity ethylene by large-scale chromatography is provided.
The technical solution adopted in the utility model is: the device of producing high-purity ethylene by large-scale chromatography, and by connecting to form with lower member: material storaging tank links to each other with the entrance of separator column by the pipe connection sampler again; The outlet of separator column is connected by connection line with first cold-trap and second cold-trap.
The beneficial effects of the utility model are, and are reasonable in design, easy to use, are desirable ethene preparation facilitiess.
Description of drawings
Fig. 1 is structural representation of the present utility model.1, material storaging tank, 2, sampler, 3, separator column, 4, analyzer-controller, 5, self-acting valve, 6, the 1# cold-trap, 7, the 2# cold-trap, 8, connection line.
Embodiment
With reference to Fig. 1, the device of producing high-purity ethylene by large-scale chromatography, by connecting to form with lower member: material storaging tank 1 is by pipe connection sampler 2, and the entrance with separator column 3 links to each other again; The outlet of separator column 3 is connected by connection line 8 with first cold-trap 6 and second cold-trap 7.
Be provided with self-acting valve 5 between described separator column 3 and first cold-trap 6 and second cold-trap 7.
Connect into analysis controller 4 between described separator column 3 and the self-acting valve 5.
This device can be used for large-scale chromatography and prepares high-purity ethylene: the unstripped gas (ethene) of the certain volume of packing in material storaging tank 1, squeeze into carrier gas stream (as hydrogen by sampler 2, nitrogen) in, namely taken away by carrier gas, adsorb and desorption through chromatography column 3, be separated into several chromatographic peaks, observe sepn process with analyzer-controller 4, determine the normal operational position of self-acting valve 5 then, wishing to get component (as ethene, Trimethylmethane) cuts out respectively, send into 1# cold-trap 6 and 2# cold-trap 7, by freezing or condensation, it is separated from carrier gas, thereby obtain highly purified ethylene product.
Its advantage is the product yield height, purity height (99.999%), and impurity is few, and separates easily, except product itself, does not have other harmful, poisonous by products, operates also more conveniently, is the ideal device that high-purity ethylene prepares.
Claims (3)
1. the device of producing high-purity ethylene by large-scale chromatography is characterized in that: by connecting to form with lower member: material storaging tank links to each other with the entrance of separator column by the pipe connection sampler again; The outlet of separator column is connected by connection line with first cold-trap and second cold-trap.
