During the production process, due to improper operation, the pressure and temperature in the kettle will increase rapidly. If you do not take necessary measures to reduce the temperature and pressure in the kettle, it will cause the explosion of the hydrolysis kettle, causing immeasurable losses, and even casualties
The pressure relief of the hydrolysis kettle is mainly realized by the high-altitude discharge of the emptying pipe installed on the top of the hydrolysis kettle. However, resorcinol is a toxic substance, and the resorcinol gas-liquid mixture sprayed from the emptying pipe entrains part of the sulfuric acid. Sulfuric acid is a strong corrosive substance. If it is discharged directly, the falling resorcinol and sulfuric acid will not only cause environmental pollution, but also cause corrosion of adjacent equipment and human injury.

Embodiment approach 1
[0025] This embodiment provides a high temperature and high pressure liquid recovery storage tank, such as figure 1 with 2 As shown, it is mainly composed of a tank body 1 with a top opening 2, a receiving pipe 11, a gas-liquid dispersion baffle 15, a buffer cover plate 3, a tank liquid outlet 16, a bolt rod fixing plate 6 and two bolt rods 9, and the gas-liquid dispersion The baffle plate 15 is welded and fixed on the inner bottom of the tank body 1, the bolt rod fixing plate 6 is welded and fixed on the inner top of the tank body 1, the tank liquid outlet 16 is opened on the bottom side of the tank body 1, and the liquid outlet at the bottom of the receiving pipe 11 exits from the tank body The top opening of 1 extends into the bottom of the tank body 1 and is set facing the gas-liquid dispersion baffle 15, and there is a preset distance between the liquid outlet at the bottom end of the receiving pipe 11 and the gas-liquid dispersion baffle 15, and the gas-liquid dispersion...
Embodiment approach 2
[0029] This embodiment is a further improvement of Embodiment 1. The main improvement is that: in Embodiment 1, under the action of the high-temperature, high-pressure gas-liquid mixture, the buffer cover 3 moves upward along the outer wall of the bolt rod 9 and the receiving pipe 11. When moving to the highest point, it may collide violently with the bolt rod fixing plate 6 above; after the energy in the gas-liquid mixture is absorbed by the buffer cover 3, the buffer cover 3 will move along the bolt rod 9 and the receiving pipe 11 The outer wall of the tank moves downward to the lowest point, and when the buffer cover 3 moves to the lowest point, it may collide violently with the gas-liquid dispersion baffle 15 below; the existence of the above situation is not conducive to the structural stability of the storage tank ; But in the present embodiment, the above defects can be avoided.
[0030] Specifically, in the high-temperature and high-pressure liquid recovery storage tan...
Embodiment approach 3
[0033] This embodiment is a further improvement of Embodiment 2. The main improvement is that in Embodiment 2, when the buffer cover plate 3 moves up and down along the bolt rod 9, the upper and lower buffer springs 4 also move up and down along the bolt rod 9, Therefore, the buffer spring 4 located above the buffer cover plate 3 will impact the bolt rod fixing plate 6 when it moves to the highest point, which is not conducive to the stability of the storage tank; however, the above defects can be overcome in this embodiment.
[0034] Specifically, two spring limit nuts 5 are respectively arranged on the tops of the two buffer springs 4 on the upper side of the buffer cover plate 3, and the two spring limit nuts 5 are respectively threaded with two bolt rods 9, as figure 1 . The setting of the spring limit nut 5 can limit the buffer spring 4 on the upper and lower sides of the buffer cover plate 3 in a fixed position, so that the displacement of the buffer cover plate 3 when i...

Abstract
The invention relates to the field of high-temperature and high-pressure liquid recovery, and discloses a high-temperature and high-pressure liquid recovery storage tank. A gas-liquid dispersion baffle (15) and a bolt rod fixing rod (6) are respectively fixed on the bottom and top of the tank body (1); The liquid outlet (16) is set on the bottom side of the tank; the liquid outlet at the bottom of the receiving pipe (11) extends into the tank from the top opening (2) of the tank and is set facing the gas-liquid dispersion baffle; two The bottom ends of the bolt rods (9) are threaded on both sides of the gas-liquid dispersion baffle, and the top ends are threaded on both sides of the bolt rod fixing plate; the two sides of the buffer cover (3) are respectively sleeved on two bolt rods The upper and middle sleeves are placed on the outside of the receiving pipe, and are located between the bolt rod fixing plate and the gas-liquid dispersion baffle. The storage tank can absorb most of the energy in the high-temperature and high-pressure liquid mixture, collect most of the liquid phase and discharge the gas phase with significantly lower pressure, reduce pollution, and reduce the damage to the human body when the high-pressure gas phase is discharged.
Description
technical field [0001] The invention relates to the field of high-temperature and high-pressure liquid recovery, in particular to a high-temperature and high-pressure liquid recovery storage tank. Background technique [0002] Resorcinol is an extremely important organic chemical raw material, mainly through concentrated sulfuric acid and m-phenylenediamine at 232 It is produced by hydrolysis at 2°C and 3MPa, and the hydrolysis process is mainly carried out in a hydrolysis kettle. During the production process, due to improper operation, the pressure and temperature in the kettle will increase rapidly. If the necessary measures are not taken to reduce the temperature and pressure in the kettle, it will cause the explosion of the hydrolysis kettle, causing immeasurable losses and even casualties. The pressure relief of the hydrolysis kettle is mainly realized by the high-altitude discharge of the emptying pipe installed on the top of the hydrolysis kettle. However, resorcin...
