Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a schematic structural diagram of a conventional dry gas tank sealed by a double-section rubber membrane, generally, a tank body comprises a tank bottom plate 1, a tank top plate 5 and a side plate 3, a piston 7 and a T baffle 8 are arranged in the tank body, and the piston 7 and the T baffle 8 can move up and down in the tank body; in the running process of the gas holder, the gas is fed and discharged through the up-and-down movement of the piston 7 and the T baffle plate 8, when the T baffle plate 8 is not contacted with the piston 7, the T baffle plate 8 is supported by the T baffle plate bracket 2, and after the piston 7 is lifted to be contacted with the T baffle plate 8, the T baffle plate 8 can be lifted to be separated from the T baffle plate bracket 2; in the up-and-down movement process of the piston 7 and the T baffle 8, the sealing of the cabinet body can be ensured by the rubber membrane 9.
The applicant found through research that the condition of the pressure fluctuation of the gas fed back by the downstream process is that the two states of contact and separation exist between the T baffle plate 8 and the piston 7, so that the two pressures in the cabinet body are switched, when the piston 7 is independently lifted, the gas is at the first-stage pressure, and when the piston 7 is contacted with the T baffle plate 8 and lifted together with the T baffle plate, the gas is at the second-stage pressure, and the second-stage pressure is about 0.6-0.7 kPa higher than the first-stage pressure. The pressure change belongs to a frequently neglected factor in the prior relatively rough production gas working condition and the gas pipe network pressure management, especially under the condition that the gas pressure output by a gas tank is relatively high; under the requirement of fine management of the pressure of a gas pipe network in a steel plant, the pressure change is unacceptable, and the subsequent treatment or direct application of the gas can be adversely affected. Thus, the applicant has studied this and proposed a solution.
Specifically, as shown in fig. 2 and fig. 3, the embodiment of the invention provides a constant pressure type gas tank, which comprises a tank body, a piston 7 and a T baffle 8, wherein the piston 7 and the T baffle 8 are both movably arranged in the tank body up and down, and the specific structure of the tank body is not described in detail herein. Preferably, the cabinet body is further provided with a pressure regulating counterweight 13 and a pressure regulating driving mechanism for driving the pressure regulating counterweight 13 to move up and down so as to rest on the piston 7 or separate from the piston 7, and the weight of the pressure regulating counterweight 13 is equal to the weight of the T baffle 8.

P1＝(G H +G i -G P )÷S
wherein:
p is the gas pressure value, kPa;
G H the weight of the piston 7, t;
G i the weight t of the pressure regulating counterweight 13;
G p to level the weight 10, t;
s is the sectional area of the cabinet body.
Fig. 3 shows the working condition of the gas tank when the T-baffle 8 is in contact with the piston 7: after the piston 7 contacts the T baffle 8, the pressure regulating counterweight 13 is lifted away from the piston 7 plate by the pressure regulating driving mechanism, and the gas pressure in the tank body is provided by subtracting the weight of the leveling counterweight 10 from the weight of the piston 7 and the weight of the T baffle 8, namely:
P2＝(G H +GT - G P )÷S
wherein:
p is the gas pressure value, kPa;
G H the weight of the piston 7, t;
G T the weight of the baffle plate T is the weight of the baffle plate T8, T;
G P to level the weight 10, t;
s is the sectional area of the cabinet body.
By setting the weight of the pressure regulating weight 13 and the weight of the T-baffle 8 equal, p1=p2 can be calculated, so that the pressure is kept constant throughout the operation of the gas tank.
The constant pressure type gas holder that this embodiment provided through setting up pressure regulating counter weight 13 to cooperate with the activity condition of piston 7 and T baffle 8, when piston 7 and T baffle 8 did not contact, make pressure regulating counter weight 13 fall to place on piston 7, when piston 7 and T baffle 8 contact, lift up pressure regulating counter weight 13, its weight just can offset the weight of T baffle 8 and annex thereof, thereby, can realize the stability of gas holder gas storage pressure through the switching of pressure regulating counter weight 13 position, guarantee the gas quality for the downstream process, therefore can improve gas holder's result of use and application scope.

The compression spring 15 ensures that the wire rope 14 can be tightened without creating excessive tension when the pressure regulating counterweight 13 is dropped onto the plate of the piston 7.
Further, the structure of the constant-pressure type gas tank is optimized, and since lifting or dropping of the pressure regulating balance weight 13 is required to be realized through the pressure regulating driving mechanism, and preferably, the pressure regulating balance weight 13 is lifted at the moment when the piston 7 is in contact with the T baffle plate 8 and the pressure regulating balance weight 13 is dropped at the moment when the piston 7 is separated from the T baffle plate 8, the constant-pressure type gas tank further preferably further comprises an automatic control mechanism for controlling whether the pressure regulating driving mechanism works or not, the automatic control mechanism comprises a main control machine, the pressure regulating driving mechanism is electrically connected with the main control machine, automatic control is realized through the automatic control mechanism, and the stability of the gas storage pressure in the gas tank is ensured.

In a further embodiment, as shown in fig. 2 and 3, the position detection mechanism comprises a displacement sensor 19, which displacement sensor 19 is arranged on the T-baffle 8. The displacement of the T-baffle 8 in the tank is known by the displacement sensor 19, and thus whether the piston 7 is in contact with the T-baffle 8 is known.
Preferably, a combination of the two embodiments is adopted, that is, the camera 20 is adopted in cooperation with the displacement sensor 19 to detect the relative positional relationship between the piston 7 and the T-baffle 8.
