Embodiment Construction

[0018] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0019] Such as figure 1 As shown, the concentrated sulfuric acid storage device 100 according to the embodiment of the present invention includes a tank body 1 , a first acid inlet pipe 7 , a second acid inlet pipe 10 , a dryer 2 , a third pipe 8 and a fourth pipe 3 .

[0020] The tank body 1 is used to hold concentrated sulfuric acid, and the top wall of the tank body 1 has a communication port. One end of the first acid inlet pipe 7 extends into the concentrated sulfuric acid in the tank body 1, and the other end of the first acid inlet pipe 7 extends out of the tank body 1 and communicates with a concentrated sulfuric acid production device (not shown). One ...

Abstract

The invention discloses a concentrated sulfuric acid storage device. The concentrated sulfuric acid storage device comprises a tank body, a dryer, a first acid inlet pipe, a second acid inlet pipe, a third pipe and a fourth pipe; the tank body is used for filling concentrated sulfuric acid; a communicating opening is formed in the top wall of the tank body; one end of the first acid inlet pipe extends into the concentrated sulfuric acid in the tank body; the other end of the first acid inlet pipe extends out of the tank body; one end of the second acid inlet pipe communicates with the first acid inlet pipe; the dryer is located on the outer side of the tank body; a filler layer and a spraying pipe located above the filler layer are arranged in the dryer; the other end of the second acid inlet pipe communicates with the spraying pipe in the dryer; the dryer is provided with an air inlet, a liquid outlet and an air outlet; the air outlet is located below the filler layer; one end of the third pipe communicates with the liquid outlet; the other end of the third pipe extends into the concentrated sulfuric acid in the tank body; one end of the fourth pipe communicates with the air outlet; and the other end of the fourth pipe communicates with the communicating opening. The concentrated sulfuric acid storage device disclosed by the embodiment of the invention is low in operation cost and simple to operate.

Description

technical field [0001] The invention relates to the technical field of liquid storage tanks, in particular to a concentrated sulfuric acid storage device. Background technique [0002] The ventilation pipe of the concentrated sulfuric acid storage device is directly connected to the atmosphere. When the liquid level in the storage device drops or the volume of the air above the liquid level shrinks due to temperature drop, the moisture in the outside air will directly enter the storage device with the air and communicate with the storage device. The concentrated acid droplets remaining on the tank wall above the inner liquid level mix to form dilute sulfuric acid, which will directly cause corrosion of the steel concentrated sulfuric acid storage device. [0003] For this reason, measures such as nitrogen blanketing device, installation of air desiccant, and increase of tank wall corrosion allowance have been proposed in the related art to reduce the risk of corrosion leakag...
