Description
Technical field
The present invention relates to technical field of chemical, more particularly, to a kind of feeding method of negative reaction container.
Background technology
Many chemical products productions are carried out under condition of negative pressure at present, and reaction vessel need to be in negative pressure shape in production process
State.
But sometimes during negative reaction, it need to be added materials in the reaction vessel of negative pressure state, negative pressure state
Under to add materials be a problem, existing adding method is cumbersome, and addition device structure is complicated, and cost is higher, is unfavorable for improving life
Produce efficiency and reduce cost.
The content of the invention
In view of the shortcomings of the prior art, the technical problems to be solved by the invention are to provide a kind of feeding intake for negative reaction container
Method, to reach the easy purpose of feeding method.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of feeding method of negative reaction container,
The negative reaction container is connected with feed intake pipeline and vacuum lines, on the pipeline that feeds intake from negative reaction container to
Charge door is sequentially provided with switch valve I, pressurized tank, switch valve IV, and the vacuum lines are provided with switch valve III and switch valve V, institute
State and be connected between the vacuum lines between switch valve III and switch valve V and pressurized tank by by-pass line, by-pass line is provided with regulation
Valve；
The feeding method comprises the following steps：
1) pressurized tank is in atmospheric pressure state, and material, closing switch valve IV are added from the charge door for the pipeline that feeds intake；
2) pressure value for setting pressurized tank is equal to the pressure value of negative reaction container, and valve is controlled to adjust by pressure sensor,
Until the pressure value of two pressure sensors on pressurized tank and negative reaction container is equal；
3) closing switch valve V, switch valve III and regulating valve are opened；
4) switch valve between pressurized tank and negative reaction container is opened, material enters in negative reaction container.
Wherein, it is equipped with pressure sensor on pressurized tank and the negative reaction container.
Switch valve II is provided with the pipeline that feeds intake between pressurized tank and switch valve I.
The pipeline that feeds intake is vertical pipeline.
The present invention compared with prior art, has advantages below：The feeding method is regulated and controled by valve, in negative
The reaction vessel dosing operation of pressure condition is very convenient, and input cost is low, and feeding intake only need to control each valve, and feed intake simplicity.
Brief description of the drawings

Sensor detects its pressure respectively.
Vacuum lines C is provided with switch valve III 4 and switch valve V 8, wherein, switch valve III is set close to negative reaction container
Put.
It is connected between vacuum lines and pressurized tank between switch valve III and switch valve V by by-pass line, is set on by-pass line
There is regulating valve 3, regulating valve 3 is electric control valve.
Switch valve I, switch valve II, switch valve III, switch valve IV, switch valve V are electric switching valve, and control is easy.
The feeding method of negative reaction container, dosing operation method comprise the following steps：
Pressurized tank is in atmospheric pressure state, and material, closing switch valve IV are added from the charge door for the pipeline that feeds intake；
The pressure value for setting pressurized tank is equal to the pressure value of negative reaction container, controls to adjust valve by pressure sensor, directly
The pressure value of two pressure sensors is equal on to pressurized tank and negative reaction container；
Closing switch valve V, open switch valve III and regulating valve；
The switch valve between pressurized tank and negative reaction container is opened, material enters in negative reaction container, completes material
Addition.
It is simple in construction, multiple valves are only set up on pipeline, material need to only control each valve, and feed intake letter
Just, equipment cost is low.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that present invention specific implementation is not by aforesaid way
Limitation, as long as employ the present invention design and technical scheme carry out various unsubstantialities improvement, or it is not improved will
The design and technical scheme of the present invention directly applies to other occasions, within protection scope of the present invention.
