Description
Technical field
The present invention relates to a kind of pressure-regulating device, particularly relate to a kind of refining and cracking surge tank nitrogen pressure regulation automaton.
Background technology
Refining surge tank and cracking surge tank are all the indispensable devices of coal chemical technology, and they play vital effect for safety in production.According to technologic requirement, the tank deck of refining surge tank and cracking surge tank all should be in barotropic state all the time, if refining surge tank or cracking surge tank carry out the action of charging or discharging, in its tank, the lifting of liquid level will inevitably make pressure in tank change, thus the normal operation of the refining surge tank feed pump of impact or cracking surge tank feed pump, the feed rate fluctuation of reaction increases, and then the stability that reaction system is operated is restricted.Therefore, the pressure control device reacted in a kind of pressure that can effectively control in refining and cracking surge tank, stable can is badly in need of.
Summary of the invention
The present invention, for above-mentioned the deficiencies in the prior art, provides a kind of refining and cracking surge tank nitrogen pressure regulation automaton.
Refining and cracking surge tank nitrogen pressure regulation automaton of the present invention, comprise cracking surge tank, refining surge tank and nitrogen pressurising pipeline to form, this device is the top that the top pipeline of refining surge tank is connected to cracking surge tank, the top of cracking surge tank is connected with nitrogen pressurising pipeline through nitrogen gas control valve, cracking surge tank top be provided with the blow-down pipe be connected through atmospheric valve between nitrogen gas control valve, nitrogen gas control valve and atmospheric valve circuit connect pressure balance on-off controller.
As a further improvement on the present invention, the top of described cracking surge tank is provided with manual blow-down pipe and is provided with manual blow-down pipe control valve.
Refining and cracking surge tank nitrogen pressure regulation automaton of the present invention, reasonable in design, operates steadily, and Stress control is stablized.Through actual verification, namely the present invention can ensure pressure stability in refining surge tank and cracking surge tank, ensures again the normal operation of the feed pump of refining surge tank and cracking surge tank, and then reaches safety and stability production object.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Embodiment 1
The present invention refines and cracking surge tank nitrogen pressure regulation automaton, comprise cracking surge tank 1, refining surge tank 2 and nitrogen pressurising pipeline 9 to form, this device is the top top pipeline 3 of refining surge tank 2 being connected to cracking surge tank 1, the top of cracking surge tank 1 is connected with nitrogen pressurising pipeline 9 through nitrogen gas control valve 5, cracking surge tank 1 top be provided with the drop out line 10 be connected through atmospheric valve 6 between nitrogen gas control valve 5, nitrogen gas control valve 5 and atmospheric valve 6 circuit connect pressure balance on-off controller 4.
Embodiment 2
As shown in Figure 1, the present invention refines and cracking surge tank nitrogen pressure regulation automaton, comprise cracking surge tank 1, refining surge tank 2 and nitrogen pressurising pipeline 9 to form, this device is the top top pipeline 3 of refining surge tank 2 being connected to cracking surge tank 1, the top of cracking surge tank 1 is connected with nitrogen pressurising pipeline 9 through nitrogen gas control valve 5, cracking surge tank 1 top be provided with the blow-down pipe 10 be connected through atmospheric valve 6 between nitrogen gas control valve 5, nitrogen gas control valve 5 and atmospheric valve 6 circuit connect pressure balance on-off controller 4.The top of described cracking surge tank is provided with manual blow-down pipe 7 and is provided with manual blow-down pipe control valve 8.
When the discharging pump running of refining surge tank and cracking surge tank is fuel-displaced, pressure drop in tank, at this moment nitrogen gas control valve 5 is opened, atmospheric valve 6 closes, and nitrogen enters cracking surge tank, enter refining surge tank by nitrogen pressurising pipeline 9, guarantee that in tank, pressure stability is in safe range; When the feed pump running oil-feed of refining surge tank and cracking surge tank, in tank, pressure can raise, now nitrogen gas control valve 5 closes, atmospheric valve 6 leaves, in refining surge tank, gas enters cracking surge tank, in cracking surge tank, gas enters blow-down pipe 10, and then ensures that in tank, pressure stability is in safe range.When charging or load unexpected excessive time, manual blow-down pipe 7 can be opened and carry out emergency pressure adjustment.Nitrogen gas control valve 5 and atmospheric valve 6 are controlled by pressure balance on-off controller 4, the signal that this pressure balance on-off controller 4 exports controls the action of nitrogen gas control valve 5 and atmospheric valve 6, make nitrogen gas control valve 5 and atmospheric valve 6 all at specific operated within range, and be independent of each other.
