The utility model solves the technical scheme that its technical problem adopts: a kind of preparation facilities system of loaded catalyst, comprises gas bomb, gas control valve, spinner flowmeter, seal head, tubular heater, porcelain boat, stainless (steel) wire box, cooling surge tank, solid paraffin tower, NaOH tower, calcium chloride tower etc.It is characterized in that, in the gas inlet pipe formula heating furnace of certain flow, carry in magnetic boat feed stream that gasification the produces catalyst carrier in stainless (steel) wire box, it is loaded in catalyst carrier, unreacted raw material is through the recycling use of supercooling surge tank, not recoverablely progressively processes completely through solid paraffin tower, NaOH tower, calcium chloride tower.
Described gas bomb, gas control valve, spinner flowmeter are connected successively by gas stainless-steel pipe, and described seal head is connected with the quartz ampoule of tubular heater by sealing ring; Described tubular heater is connected with cooling surge tank with spinner flowmeter respectively by seal head; Described cooling surge tank is connected successively with solid paraffin tower, NaOH tower, calcium chloride tower.In described tubular heater, be placed with porcelain boat, stainless (steel) wire box.
The heating tube of described tubular heater is quartz ampoule or carborundum tube, and tubular heater seal head is cut with the groove that the degree of depth is 0.1mm-5mm; Sealing ring is enclosed within the groove of seal head, and sealing ring thickness is 1-4mm, sealing ring resistance to compression 5-10MPa; In heating tube, being placed with stainless (steel) wire box diameter is 5mm-100mm; The stainless (steel) wire aperture using for 0.1-300 μ m, the stainless (steel) wire box number of plies be 1-8 layer, carrier is fixed in stainless (steel) wire box.
Described surge tank is double-layer stainless steel structure, in the middle of ectonexine stainless steel, is hollow, in the middle of two-layer stainless steel, is connected with recirculated cooling water, and ectonexine stainless steel spacing is 2-25mm.
Described catalyst is prepared system can be divided into three parts: the gas handling system 1) being made up of gas bomb, gas control valve, spinner flowmeter etc.; 2) the catalyst preparation system being formed by seal head, tubular heater, porcelain boat, stainless (steel) wire box etc.; 3) exhaust treatment system being formed by cooling surge tank, solid paraffin tower, NaOH tower, calcium chloride tower etc.
In the utility model one detailed description of the invention, gas flow is in spinner flowmeter enters official heating furnace, in pipe, carrying gas-phase activity component reacts with catalyst carrier, make the uniform active constituent of catalyst surface load last layer, unreacted gas-phase activity component reclaims the complete gas of unreacted by cooling surge tank together with gas, then remains a small amount of gaseous component and absorbs respectively by follow-up solid paraffin tower, NaOH tower, calcium chloride tower materials such as removing organic principle, acid, moisture successively.Wherein, control gas and enter speed and the flow of tubular heater by controlling spinner flowmeter, and the flow of gas has determined the size of condensate buffering tank, solid paraffin tower, NaOH tower, calcium chloride tower, has more determined the length in reaction time and the uniformity of catalyst surface active component.Load the catalyst carrier of active constituent can directly in described tubular heater, complete roasting, directly obtain the catalyst of activation.
If, not containing acidic materials, described exhaust treatment system can omit NaOH tower in the utility model.Therefore, will be understood by those skilled in the art that for described exhaust treatment system and can build rational equipment according to concrete needs.
The utility model has overcome conventional tubular heating furnace preparing that in loaded catalyst process, catalyst cupport is inhomogeneous, system sealing is poor, unreacting gas can not be recycled again and the shortcoming such as tail gas pollution environment, has produced certain economy and environment protecting.
Therefore the easy device system that prepared by loaded catalyst described in the utility model has important actual application value, can be applied to industrial production.
Below in connection with accompanying drawing and detailed description of the invention, the utility model is described in detail, but those skilled in the art are to be understood that, those skilled in the art, according to the technological know-how that discloses and itself have of the present utility model, can change or revise the utility model.Therefore, scope of the present utility model is not limited to following embodiment, and should only be limited by claims.
