During pipe 3, absorbed by the water-stop 8 of the V words of acid-proof flexible pipe 3 or U-shaped bottom, it is to avoid sour gas volatilizees during discharging.
Operation principle of the present utility model and concrete operations are described further below：
First, operation principle
One pressure equaliser 2 is first installed in the discharge port of strong acid storage tank 1, one is installed behind pressure equaliser 2
The acid-proof flexible pipe 3 of individual anti-acid corrosion, during work acid-proof flexible pipe 3 by hose forming device 4 downward generation V words or U-shaped,
The bottom injection running water of V words or U-shaped flexible pipe.
2nd, sour process is unloaded
1) when strong acid tank car 6 unloads acid, unload acid tube 5 and unload acid, hose forming device 4 to strong acid tank car 6 through acid-proof flexible pipe 3
Acid-proof flexible pipe 3 is formed downward V words or U-shaped, originally water submerged is injected in the bottom of V words or U-shaped flexible pipe and passes through V
Acid tube 5 is unloaded in word or U-shaped flexible pipe bottom.
2) when unloading acid because the internal upper part volume of air of strong acid storage tank 1 diminishes, air pressure increase forms substantial amounts of air
Overflowed with strong acid mixed gas from discharge port, when V word or U-shaped bottom of the strong acid gas by acid-proof flexible pipe 3, due to strong
Acid is highly soluble in water, and strong acid gas is absorbed at once, and the air in strong acid storage tank 1 is discharged by pressure equaliser.
When the 3rd, not unloading the day-to-day operation of acid：
During the routine use of strong acid storage tank 1, because strong acid is easy to volatilization, the strong acid gas of volatilization passes through the bottom of acid-proof flexible pipe 3
During the water-stop 8 of the V in portion or U-shaped pipe, it is only absorbed by the water at once, water-stop effect is played to the strong acid solution of strong acid storage tank 1.
4th, after the running water of the bottom of acid-proof flexible pipe 3 absorbs strong acid gas, concentration increase, assimilation effect weakens, at this moment used
The bottom of acid-proof flexible pipe 3 is become straight by rope and fixed pulley 44 toward pull-up from V words or U-shaped, makes the bottom of acid-proof flexible pipe 3
Acid-bearing wastewater flows to strong acid storage tank 1, causes environmental problem without causing acid-bearing wastewater to overflow to ground, then recovers original again
V words or U-shaped flexible pipe position, refill running water, water-stop carried out to strong acid gas with running water, to carry out more
Good tail gas absorption.
5th, the utility model is through implementing, and when unloading acid, no tail gas is evaporated, and does not influence environment, in day-to-day operation
When, strong acid gas is not also excessive.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvements and modifications can also be made, these change
Enter and retouch and also should be regarded as protection domain of the present utility model.
