Description
Technical field
The utility model relates to a kind of gas mixer, and especially the device of mixing of hydrogen and nitrogen gas body proportioning and conveying is used for the gas supply of fluorescent material tunnel reduction furnace reduction reaction.
Background technology
High temperature sintering synthesizes and reduction is the conventional production method of fluorescent material; The high temperature reduction of fluorescent material carries out in high temp tunnel formula reduction furnace, wherein needs sufficient hydrogen-nitrogen mixture gas to participate in reaction.In the hydrogen-nitrogen mixture gas, hydrogen is made by the ammonia decomposition, and nitrogen is formed by liquid nitrogen gasification, and two kinds of gases mix in the input reduction furnace according to a certain ratio then.
The making of existing hydrogen-nitrogen mixture gas, and the operation that applies hydrogen-nitrogen mixture gas in reduction furnace are that operating personnel rule of thumb carry out mostly.This mode of operation is subjected to influence that people's thought mood changes greatly, and the proportioning of hydrogen nitrogen and the input quantity of gas are difficult to control accurately; Thereby product quality is difficult to further raising.
The utility model content
The purpose of this utility model is the deficiency that will overcome the above-mentioned background technology, and a kind of gas mixer is provided, and this device should have hydrogen and nitrogen gas body proportioning characteristics accurate, simple to operation.
The technical scheme that the utility model provides is:
Gas mixer comprises that one connects the hydrogen nitrogen proportioning jar of ammonia decomposition device and liquid nitrogen plan respectively by hydrogen pipe and nitrogen tube, and a buffering air accumulator that is communicated with hydrogen nitrogen proportioning jar by carrier pipe; Described buffering air accumulator also is connected to the output channel that is communicated with reduction furnace gas access port.
Described hydrogen pipe and nitrogen tube are to connect hydrogen nitrogen proportioning jar on the top, both sides of hydrogen nitrogen proportioning jar.
Flowmeter, control valve and Pressure gauge are housed respectively on described hydrogen pipe, the nitrogen tube and on the carrier pipe.
The beneficial effects of the utility model are: because through twice mixing, so hydrogen and nitrogen gas body proportioning is accurate and gas mixes, output pressure is stable and air demand is big; For the mixing of low-pressure gases such as preparing hydrogen by ammonia decomposition gas and liquid nitrogen gasification gas also particularly suitable.In addition, operate also particularly simple and conveniently, help the raising of product quality and the raising of production efficiency.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model.
The specific embodiment
Gas mixer comprise that one connects the hydrogen nitrogen proportioning jar 3 of ammonia decomposition device 1 and liquid nitrogen plan 2 respectively by hydrogen pipe 5 and nitrogen tube 6, and one passes through the buffering air accumulator 4 that carrier pipe 7 is communicated with hydrogen nitrogen proportioning jar; Described buffering air accumulator 3 also is connected to the output channel 8 that is communicated with reduction furnace gas access port.Show among the figure: described hydrogen pipe 5 and nitrogen tube 6 are to connect hydrogen nitrogen proportioning jar on the top, both sides of hydrogen nitrogen proportioning jar 3.
Described hydrogen pipe 5 and nitrogen tube 6 are equipped with flowmeter A, control valve B and Pressure gauge C respectively.
Operation principle of the present utility model is:
In addition: ammonia decomposition device is that ammonia decomposes the device (directly outsourcing) that hydrogen nitrogen mixes gas; Reach 75% but the hydrogen ratio is higher, be used as pure hydrogen temporarily.Nitrogen produces after by liquid nitrogen gasification.
Also have among the figure: sewage draining exit D, exhaust outlet E.
