Description
Technical field
The utility model is related to the distilling apparatus in a kind of hydrogen fluoride production technique, it is adaptable in hydrogen fluoride production technique
Rectifying and degasser.
Background technology
In with Fluorspar Powder and sulfuric acid as the production technology of raw material production anhydrous hydrogen fluoride, traditional fractionating device is in essence
Evaporate tower reactor and coil pipe is installed in degassing tower reactor both sides, as shown in Fig. 1, Fig. 2 in Figure of description, the coil arrangement spirals in bending
Shape, inside is full of steam medium, and outer surface is directly contacted with hydrogen fluoride, i.e., make liquid by the heat of steam generation in coil pipe
The hydrogen fluoride evaporative fractionation of state.Limited by space, the area of heat-supply service of the coil arrangement is limited, the heat distribution at each position is more uneven
Even, this control to cut point is totally unfavorable, if cut point control is bad, when particularly temperature fall is big, and disk
Pipe easily perforation rupture, coil pipe is once perforated rupture, then mean that the steam in coil pipe is directly contacted with hydrogen fluoride, and this will product
The violent reaction of life, badly damaged fractionating device, it is necessary to parking maintenance immediately.According to statistics, the heater of coiled, average longevity
Life must just pull down within 35~40 days maintenance repair welding or replacing, this strong influence production it is lasting, stable, safely run.Together
When also due to the generation of steam needs special boiler, it is relatively costly.And vapor (steam) temperature is higher than 100 DEG C, and in course of conveying
In water be will also condense into due to the loss of heat, a part, this part water need to be discharged in time, will otherwise have a strong impact on holding for steam
Continuous supply, thus also need that corresponding drain valve is installed.
Utility model content
The purpose of this utility model is the problem of distillation equipment presence in the production technology for overcome above-mentioned traditional hydrogen fluoride, with
Shell and tube hydrogen fluoride distilling apparatus replaces traditional coiled distilling apparatus, so as to realize the efficient section of hydrogen fluoride fractionation process
Energy.
To achieve the above object, the utility model is adopted the following technical scheme that：
Shell and tube hydrogen fluoride distilling apparatus, in cylinder, inside is provided with hot water buffer area, arranged type water inlet for its outer surface
Pipe, arranged type outlet pipe, hot water inlet are communicated by water inlet pipe with hot water buffer area, and hot water outlet is delayed by outlet pipe with hot water
Area is deposited to communicate.
After using shell and tube hydrogen fluoride distilling apparatus, shell and tube hydrogen fluoride distilling apparatus is installed to hydrogen fluoride rectifying tower reactor
With degassing tower reactor in, by hydrogen fluoride production reaction converter UTILIZATION OF VESIDUAL HEAT IN project produce hot water, by hot water inlet pass through into
Water pipe is flowed into hot water buffer area, then is flowed out through delivery port by outlet pipe, the hot water preserved in hot water buffer area and water inlet pipe and water outlet pipe
The distilling apparatus of cylinder is set to keep temperature, because the temperature needed for hydrogen fluoride fractionation process only needs 55~65 DEG C, shell and tube fluorine
The temperature for changing hydrogen distilling apparatus cylindrical surface has reached the required temperature of hydrogen fluoride fractionation, so as to smoothly realize dividing for hydrogen fluoride
Evaporate.
Compared with conventional disc pipe type heating device, there is significant progressive effect using shell and tube hydrogen fluoride distilling apparatus.One
It is that shell and tube fractionating device uses the hot water produced in hydrogen fluoride reaction converter UTILIZATION OF VESIDUAL HEAT IN project, and coil tube type heating is filled
Put and use water vapour, it is necessary to special boiler, so coil tube type heating installation cost is higher；Two is shell and tube heating surface (area) (HS
It is whole cylinder, its heating surface (area) (HS is big compared with coiled, thus heating effect is good；Three is the snake of coil heater convolution bending
Shape pipe not only forms certain resistance, influences the mobility of steam, but also local temperature can be caused too high.Particularly because of temperature control
System is bad, causes in kettle liquid hydrogen fluoride to make coil pipe exposed because a large amount of evaporations cause liquid levels to decline, the drop under reflux condensation mode from
Certain altitude falls and directly drops on exposed coil pipe, coil pipe is perforated.And shell and tube distilling apparatus hot water is from tubulation
Flow into, and internally form certain hot water buffer area, because tubulation structure is through type, have space again between tubulation and tubulation,
It is easily controlled compared with steam with good circulation, and hot water temperature, hot water can circulate profit by corresponding heater
With.

Specific embodiment
As shown in Figure 1 and Figure 2, in bending spiral, inner filling water steam leads to its structure of traditional coil heater
Crossing the heat effect of water vapour makes coil heater outer surface produce heat, so that liquid hydrogen fluoride evaporative fractionation.
As shown in Figure 3, Figure 4, the utility model replaces conventional disc pipe still with shell and tube hydrogen fluoride distilling apparatus,
In cylinder, inside is provided with hot water buffer area 5, arranged type water inlet pipe 4, arranged type for shell and tube hydrogen fluoride distilling apparatus outer surface 3
Outlet pipe 6, hot water inlet 2 is communicated by water inlet pipe 4 with hot water buffer area 5, and hot water outlet 1 is cached by outlet pipe 6 with hot water
Area 5 communicates.When shell and tube hydrogen fluoride distilling apparatus works, by the heat produced in hydrogen fluoride production reaction converter UTILIZATION OF VESIDUAL HEAT IN project
Water flows into hot water buffer area 5 by hot water inlet 2, then flows out hot water outlet 1, hot water buffer area 5, water inlet pipe by outlet pipe 6
4th, the hot water that outlet pipe 6 is preserved makes shell and tube hydrogen fluoride distilling apparatus outer surface keep certain temperature, so that the fluorine of liquid
Change hydrogen distillation, realize fractional distillation process.
Compared with traditional coil heater, the utility model shell and tube hydrogen fluoride distilling apparatus cost is substantially reduced,
Heating surface (area) (HS is big, and heating effect is good, and equipment is relatively reliable and durable.After shell and tube hydrogen fluoride distilling apparatus puts into production, the life-span
Equal 35 days by Yuanping City, extend to current 15 months or so, temperature control deviation is accurate to current ± 2 DEG C, base by former ± 10 DEG C
The undesirable condition of this elimination rectifying tower reactor or degassing tower bottoms position deficiency or overfill caused by temperature is difficult to control.
