Abstract
The utility model discloses a positive pressure type graphite synthesizing furnace for hydrochloric acid, comprising an upper furnace body, a lower furnace body, an upper furnace cylinder, a lower furnace cylinder, a graphite furnace cylinder, a hydrogen inlet, a chlorine gas inlet, a hydrogen lamp tube and a chlorine gas lamp tube, wherein, the chlorine gas lamp tube is arranged inside the hydrogen lamp tube, the upper end of the chlorine gas lamp tube is sealed, and the tube wall of the chlorine gas lamp tube is provided with small outlet holes. The utility model uses a positive pressure type production technology and is applied to producing acid and direct feeding HCL gas exchange technology; with high safety and reliability and large yield capability, the utility model thoroughly alters the conjuncture that two-in-one synthesizing furnaces in China can not directly feed high-quality HCL gas.
Description
The utility model discloses a kind of hydrochloric acid graphitic synthetic furnace, more particularly disclose a kind of positive-pressure type hydrochloric acid graphitic synthetic furnace.
A kind of graphite hydrochloric acid synthetic furnace is disclosed in Chinese patent CN-93229340, existing hydrochloric acid synthetic furnace is reequiped, this stove has overcome the deficiency of hydrochloric acid synthetic furnace in the prior art, but this stove still exists end flue temperature too high, the transportation rapid wear, also there are certain disadvantage in effective cooling of body of heater and reinforcing mass transfer, heat transfer process, thereby have influenced the quality product and the output of hydrochloric acid.
The purpose of this utility model provides a kind of defective that can overcome the prior art existence, and mixes, and burning is thorough, production efficiency is high, the positive-pressure type hydrochloric acid graphitic synthetic furnace of long service life.
This and other purpose of the present utility model will and be described by following detailed description and further embody and set forth.
Positive-pressure type hydrochloric acid graphitic synthetic furnace of the present utility model, comprise upper furnace body, lower furnace body, upper furnace tube, following stove tube, graphite furnace tube, hydrogen inlet, chlorine inlet, hydrogen fluorescent tube and chlorine fluorescent tube, wherein, the chlorine fluorescent tube is in the inside of hydrogen fluorescent tube, end closure on the chlorine fluorescent tube, have the outlet aperture at its tube wall, the shape of outlet aperture can be garden shape, ellipse garden shape or other shape, as square or Polygons.
Further, positive-pressure type hydrochloric acid graphitic synthetic furnace of the present utility model, the quantity of its middle outlet aperture and aperture should be enough to make chlorine and hydrogen contact reacts, and the aspect ratio of upper furnace body and lower furnace body is 1: 1～1.5, upper furnace tube is 1: 2～3.5 with the diameter ratio of following stove tube, and body of heater is an impermeable graphite.
Positive-pressure type hydrochloric acid graphitic synthetic furnace of the present utility model is compared with the two-in-one synthetic furnace of existing suction type, has following characteristics:
1, can produce acid, can directly supply HCL gas again, and output can be controlled easily.
2, reduce last vaccum-pumping equipment-squirt pump in the system, reduced investment.
3, because the positive-pressure type synthetic furnace is operated whole synthesis system and must be moved,, overcome the unsafe factor that the suction type synthesis furnace system easily enters oxidizing gas under barotropic state so total system does not exist oxidizing gas to enter system.
4, because under the malleation condition of production, the HCL Gas Solubility is bigger than negative pressure, thereby can reduce the area of falling-film absorber, reduces the equipment gross investment.
When 5, malleation was produced, the pressure that the flue of synthetic furnace bears was less, prolonged stove work-ing life.
Below further specify the utility model by accompanying drawing and explanation thereof.
Fig. 1 is a cross-sectional schematic of the present utility model.
In Fig. 1, symbol 1 is represented upper furnace body, and symbol 2 is represented lower furnace body, and symbol 3 is represented upper furnace tube, symbol 4 representatives are the stove tube down, symbol 5 is represented the graphite furnace tube, and symbol 6 is represented hydrogen inlet, symbol 7 represent chlorine imports, symbol 8 is represented the hydrogen fluorescent tube, symbol 9 represent chlorine fluorescent tubes, symbol 10 representatives are sealed, symbol 11 representative outlet apertures.
In the utility model, positive-pressure type hydrochloric acid graphitic synthetic furnace, comprise upper furnace body 1, lower furnace body 2, upper furnace tube 3, following stove tube 4, graphite furnace tube 5, hydrogen inlet 6, chlorine inlet 7, hydrogen fluorescent tube 8 and chlorine fluorescent tube 9, wherein, chlorine fluorescent tube 9 is in the inside of hydrogen fluorescent tube 8, end closure 10 on the chlorine fluorescent tube 9, have outlet aperture 11 at its tube wall.
Further, positive-pressure type hydrochloric acid graphitic synthetic furnace of the present utility model, the quantity of its middle outlet aperture 11 and aperture should be enough to make chlorine and hydrogen contact reacts, best is more than 20, the aperture is 1～20 centimetre, the aspect ratio of upper furnace body and lower furnace body is 1: 1～1.5, and upper furnace tube is 1: 2～3.5 with the diameter ratio of following stove tube, and body of heater is an impermeable graphite.
In the utility model since other parts to be prior art known, seldom explain at this, those skilled in the art all can make correct selection according to expertise and structure shown in Figure 1.
Two-in-one synthetic furnace of the present utility model adopts the positive-pressure type production technique, is applicable to and produces acid and direct-furnish HCL respiratory exchange formula technology, have safety, reliable, production capacity is big, the efficient advantages of higher.Total system configuration rationally, but the output amplitude of accommodation is big, has thoroughly changed the situation that the two-in-one synthetic furnace of China can not direct-furnish high-quality HCL gas.
