Abstract
The utility model discloses a storage tank capable of transmitting pressure, which comprises a tank body. A pressure transmitting opening is arranged on the tank body, and the pressure transmitting opening is connected with other storage tanks for storing liquid through pressure transmitting pipes. When liquid is input the storage tank, the pressure in the tank is increased, and the pressure transmitting tank can transmit pressure into the other tanks; and when liquid is output, the pressure in the tank is reduced, and then the pressure transmitting pipes can balance the pressure in all the storage tanks, so as to achieve the purposes of reducing nitrogen dosage and discharging VOC exhaust gas.
Description
Technical field
The utility model relates to a kind of storage tank, but the storage tank of pilot especially.
Background technology
Petroleum chemical industry is extensive use of the pressure tank group at present, and its gaseous pressure is independently sealed by each storage tank, when storage tank is subjected to liquid, because storage tank independently seals, pressure in the storage tank can raise, and in this time, just needs exhaust, reduce the pressure in the storage tank, in case, cause danger because the groove internal pressure is too big.When need to the liquid barrel filling in the storage tank, irritate tank car or other need in the release groove liquid time, situation about forcing down in can causing owing to the outflow of liquid again in the groove, at this time need to replenish nitrogen or other gas again, very inconvenient for the control of whole flow process like this, and to use a considerable amount of nitrogen, caused the rising of cost, when interior pressure is high, need exhaust again, contain volatile organic compound (VOC) in the waste gas, caused pollution environment.
The utility model content
But the utility model provides a kind of storage tank that can reduce the pilot of nitrogen use and VOC exhaust emission.
In order to solve above technical matters, we set up the pilot port at the groove top, the pilot port links to each other by the pilot port that connecting pipe and other are equipped with the storage tank of same product, when storage tank is subjected to liquid, pressure in the groove raises, the pilot groove can be led pressure in other the groove, makes that the storage tank pressure of liquid body can be very not high; In the time of fluid, the groove internal pressure reduces, and at this time, the pressure of connecting pipe in again can each storage tank of balance makes it too not low.
The beneficial effects of the utility model are; pilot port and connecting pipe have only been set up; make the pressure in each storage tank be able to balance; the interior pressure of storage tank can not produce big fluctuation when being subjected to liquid and fluid; thereby energy conservation has been saved in the discharging that has reduced the use amount of nitrogen and VOC environment has improved the fiduciary level of system equipment.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
But Fig. 1 is a kind of structural representation of pilot storage tank.
The specific embodiment
Shown in Figure 1, the pilot port has also been set up in the storage tank top except nitrogen inlet and VOC outlet is arranged, the pilot port links to each other by three pilot ports that the storage tank of same liquid is housed of connecting pipe and other, the gas-liquid equilibrium valve is housed on the conduit, when storage tank is subjected to liquid, pressure in the groove raises, and the gas-liquid equilibrium valve on the connecting pipe can be opened, and pressure is let out in other three storage tanks; In the time of fluid, the groove internal pressure reduces, and at this time, the gas-liquid equilibrium valve on the connecting pipe can be opened, and the pressure in each storage tank of balance reaches the purpose that reduces nitrogen use level and VOC exhaust emission.
Claims (3)
1. but the storage tank of a pilot comprises cell body, and it is characterized in that has the pilot port on the cell body, and the storage tank that same liquid is deposited by connecting pipe and other in the pilot port links to each other.
2. but the storage tank of pilot according to claim 1 is characterized in that on the described connecting pipe valve being arranged.
3. but the storage tank of pilot according to claim 2 is characterized in that described valve is the gas-liquid equilibrium valve.
