Description
Technical field
The present invention relates to field of chemical equipment, in particular to a kind of hydrogen chloride synthetic furnace.
Background technique
Hydrogen chloride is a kind of important industrial chemicals, is essential raw material in trichlorosilane synthetic reaction.Traditional
Hydrogen chloride synthetic furnace is that chlorine and hydrogen is made to burn at the lamp cap of bottom of furnace body, and reaction generates hydrogen chloride gas.Due to closing
At inevitably resulting from water in reaction, and hydrogen chloride gas becomes after dissolving in water for hydrochloric acid.
In the implementation of the present invention, the inventor finds that the existing technology has at least the following problems:
When the acid solution of bottom of furnace body has been assembled more, acid solution will connect the lamp cap of igniting and the flange of fixed ignition lamp cap
Pipe erodes, so as to cause the earlier period damage of equipment.
Summary of the invention
In order to solve problems in the prior art, the embodiment of the invention provides a kind of hydrogen chloride synthetic furnaces.The technical side
Case is as follows:
The embodiment of the invention provides a kind of hydrogen chloride synthetic furnace, the hydrogen chloride synthetic furnace includes graphite furnace body, is arranged in institute
State the graphite linings of graphite bottom of furnace body, the ignition lamp cap that the graphite linings bottom is set, the flange for fixing the ignition lamp cap
Adapter tube；
The hydrogen chloride synthetic furnace further includes the spacing collar being arranged in the graphite linings, is arranged in the graphite linings and the method
Ignition lamp cap guard circle between orchid adapter tube；The ignition lamp cap guard circle is higher than plane where the graphite linings；
The upper end of the graphite linings is arranged in the spacing collar；
The spacing collar internally tilts, in the horn-like of opening upwards；
Plane 40mm where the ignition lamp cap guard circle is higher than the graphite linings.
Specifically, the water inlet pipe nipple that the graphite bottom of furnace body is provided with lower condensate sump, is disposed adjacent with lower condensate sump；
Lower curved plate, inner coil pipe, baffle are provided in the graphite furnace body；
Upper curved plate, upper condensate sump, the water outlet pipe nipple being disposed adjacent with upper condensate sump are provided at the top of the graphite furnace body；
The lower curved plate, the inner coil pipe, the upper curved plate, which are combined, just forms three-level buffering arc.
Specifically, the inner coil pipe have R=2000mm part arc, the lower curved plate, the upper curved plate have R=
The arc of 200mm.
Technical solution provided in an embodiment of the present invention has the benefit that
By the way that a spacing collar is arranged in the upper end of graphite linings, the end of graphite linings is blocked, graphite linings can be effectively prevented
It cracks because heated；By the way that ignition lamp cap guard circle is arranged between graphite linings and flange connecting pipe, overcomes existing hydrogen chloride and close
The shortcomings that being corroded at furnace bottom ignition lamp cap and fixed ignition lamp cap flange connecting pipe, improves the service life of equipment.
Detailed description of the invention
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing.
Fig. 1 is the structural schematic diagram of hydrogen chloride synthetic furnace provided in an embodiment of the present invention；
Fig. 2 is another structural schematic diagram of hydrogen chloride synthetic furnace provided in an embodiment of the present invention.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
The embodiment of the invention provides a kind of hydrogen chloride synthetic furnace, the hydrogen chloride synthetic furnace includes graphite furnace body 1, setting
1 bottom of graphite furnace body graphite linings 2, be arranged in graphite linings 2 spacing collar 3, the igniting lamp of 2 bottom of graphite linings is set
Head, the flange connecting pipe 4 of fixed ignition lamp cap, the ignition lamp cap guard circle 5 that is arranged between graphite linings 2 and flange connecting pipe 4.
Specifically, referring to Fig. 1,1 bottom of graphite furnace body is provided with lower condensate sump 11, be disposed adjacent with lower condensate sump 11 into
Water pipe nipple 12 is provided with lower curved plate 13, inner coil pipe 14, baffle 15 in graphite furnace body 1, is provided with upper curved plate at the top of graphite furnace body 1
16, upper condensate sump 17, the water outlet pipe nipple 18 being disposed adjacent with upper condensate sump 17.
Further, inner coil pipe 14 is processed into the part arc of R=2000mm, lower curved plate 13, upper arc in the production process
Plate 16 is processed into the arc of R=200mm in process, and it is slow that these three component combinations are formed a three-level together
Arc making, therefore under the huge strong variation of device temperature remain to that equipment is prevented to be damaged.
Specifically, referring to fig. 2, the upper end of graphite linings 2 is arranged in spacing collar 3, and spacing collar 3 internally tilts, in opening
Upward is horn-like.Spacing collar 3 obliquely blocks the end of graphite linings, places graphite linings 2 because that can effectively improve by Thermal cracking
The service life of equipment.
Specifically, ignition lamp cap guard circle 5 is higher than 2 place plane of graphite linings, it is preferable that is higher than 2 place plane of graphite linings
40mm.The ignition lamp cap guard circle 5 for being higher by bottom graphite layer plane stops acid solution to ignition lamp cap and fixed ignition lamp cap
The corrosion of flange connecting pipe 4.
Technical solution provided in an embodiment of the present invention has the benefit that
By the way that a spacing collar is arranged in the upper end of graphite linings, the end of graphite linings is blocked, graphite linings can be effectively prevented
It cracks because heated；By the way that ignition lamp cap guard circle is arranged between graphite linings and flange connecting pipe, overcomes existing hydrogen chloride and close
The shortcomings that being corroded at furnace bottom ignition lamp cap and fixed ignition lamp cap flange connecting pipe, improves the service life of equipment.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
