Power resource, causes operating efficiency low, and labour intensity increases.
Content of the invention
The purpose of the present invention aim to provide a kind of directly raw material to be purified and solvent can be added glass-lined reactor, so as to effective
Improve the glass-lined reactor vacuum charging device and method of operation and purification efficiency.
For this purpose is reached, following technical solution is this invention takes：
A kind of glass-lined reactor vacuum feeding device, the valvular feed pipe of the band including connecting measuring tank and glass-lined reactor,
The vacuum system pipeline of connection vacuum tank and water-ring vacuum pump, low-pressure steam pipeline and finished barrel, it is characterised in that in charging
External one vacuum tube with vacuum valve on pipe, vacuum tube is another to be connected on vacuum system pipeline, anti-in two enamels in parallel
Answer on tank feed pipe other respectively connect a charging pipe for being provided with gate valve, the charging pipe other end is connected with finished barrel respectively, while two
The anterior each connection of root charging pipe sweeps steam pipe, sweeps that steam pipe is another to be terminated on low pressure steam pipe road.
A kind of glass-lined reactor vacuum loading method, it is characterised in that when carrying out product purification using glass-lined reactor, first
First start water-ring vacuum pump, after outlet of water-ring vacuum pump vacuum reaches 0.08MPa and stablizes, then open on vacuum tube
Vacuum valve, make in glass-lined reactor, to be changed into negative pressure；Then the glass-lined reactor for needing to add raw material or solvent is selected, is beaten
The valve on the glass-lined reactor feed pipe is opened, then is opened positioned at the gate valve that finished barrel is anterior on charging pipe, anti-using enamel
The negative pressure in tank is answered, makes product to be purified the sebific duct in finished product bucket to be purified is connected to via charging pipe and gate valve rear portion, inhale
Enter in glass-lined reactor, the finished product barrelage during suction by loading adjusts charge；Block up when material crystal occurs in charging pipe
During plug, the stop valve on low-pressure steam pipeline is opened, you can purging dredging is carried out to pipeline.
The product to be purified include 99% 3,5 xylenols, 99% 3,4 xylenols, 99% smart fluorenes, 99% dibenzofuran
And 99% indoles.
Beneficial effects of the present invention are：
Present configuration is simple, easy to operate, convenient to carry out, slightly changes, just may be used on the basis of original vacuum system line
Directly raw material to be purified and solvent are added glass-lined reactor, it is to avoid the derivation repeatedly of raw material and importing, so as to greatly save
Human-saving resource, reduces labor intensity, and effectively improves the purification efficiency of operating efficiency and product.
Description of the drawings
Fig. 1 is glass-lined reactor vacuum charging schematic device.
In figure：Glass-lined reactor 1, feed pipe 2, measuring tank 3, valve 4, sweep steam pipe 5, vacuum valve 6, vacuum tank 7,
Vacuum tube 8, vacuum system pipeline 9, low-pressure steam pipeline 10, water-ring vacuum pump 11, finished barrel 12, gate valve 13, charging
Pipe 14.
Specific embodiment
As seen from Figure 1, glass-lined reactor vacuum feeding device of the present invention, anti-with enamel including original connection measuring tank 3
Answer the vacuum system pipeline 9, low pressure of the feed pipe 2 with valve 4, connection vacuum tank 7 and water-ring vacuum pump 11 of tank 1
Jet chimney 10 and finished barrel 12, while external one vacuum tube 8 with vacuum valve 6, vacuum tube 8 on feed pipe 2
The other end be connected on vacuum system pipeline 9, can be the vacuum for forming -0.008MPa in glass-lined reactor 1.?
On the feed pipe 2 of two glass-lined reactors 1 in parallel, side has connect a charging pipe 14 for being provided with gate valve 13, charging pipe respectively
14 other end is connected with finished barrel 12 respectively, and gate valve 13 is positioned close on the position of finished barrel 12.In addition, at two
Respectively steam pipe 5 is swept in connection one for the front portion (i.e. near glass-lined reactor 1) of charging pipe 14, sweeps that steam pipe 5 is another to terminate at low pressure
On jet chimney 10.
The concrete grammar of glass-lined reactor vacuum charging of the present invention is, when product purification is carried out using glass-lined reactor 1,
Start water-ring vacuum pump 11 first, after the outlet of water-ring vacuum pump 11 vacuum reaches 0.08MPa and stablizes, then open
Vacuum valve 6 on vacuum tube 8, makes to be changed into negative pressure in glass-lined reactor 1.Then select to need to add warding off for raw material or solvent
