[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-3 , the present invention provides a technical solution: a tail gas collection device for a hydrochloric acid storage tank, including the main body 1 of the hydrochloric acid storage tank. The left side of the upper end surface of the main body 1 of the hydrochloric acid storage tank is connected with an air inlet pipe 5, and the right side of the upper end surface of the main body 1 of the hydrochloric acid storage tank is connected with one end of an air outlet pipe 6. The other end of the air outlet pipe 6 is connected with a neutralizing medicine tank 7. A partition board 701 is fixed in the neutralizing medicine tank 7, and the partition board 701 is fixedly connected with the air outlet pipe 6. The lower end surface of the partition board 701 is symmetrically and evenly fixed with vertical rods 702 on the left and right. One end of an overflow pipe 8 is connected to the upper right side of the main body 1 of the hydrochloric acid storage tank, and the other end of the overflow pipe 8 is connected to an accident pool 9. One end of a vent pipe 10 is connected to the lower right side of the main body 1 of the hydrochloric acid storage tank, and the other end of the vent pipe 10 is connected to an accident pool 9.

[0019] An observation port 101 is installed on the main body 1 of the hydrochloric acid storage tank, and the observation port 101 is connected to a sealing flange 102 through bolts; the left upper end surface of the main body 1 of the hydrochloric acid storage tank is also connected with a medicine unloading pipe 2, and the medicine unloading pipe 2 is connected with a medicine unloading pump; the lower left side of the main body 1 of the hydrochloric acid storage tank is connected to a medicine adding pump 3 through a conduit, and the medicine adding pump 3 is connected with a medicine adding pipe 4; an inlet check valve 501 is also arranged between the air inlet pipe 5 and the main body 1 of the hydrochloric acid storage tank, and the inlet check valve 501 is fixed on the main body 1 of the hydrochloric acid storage tank, and the pressure of the inlet check valve is 0.1 kp; an outlet check valve 601 is also arranged between the air outlet pipe 6 and the main body 1 of the hydrochloric acid storage tank, and the outlet check valve 601 is fixed on the main body 1 of the hydrochloric acid storage tank, and the pressure of the outlet check valve is 0.1 kp; an air distributor 602 is also fixed on the air outlet pipe 6, and the surface of the air distributor 602 is evenly provided with air holes, and the air distributor 602 is arranged in the neutralizing medicine tank 7; a control valve 1001 is also installed on the vent pipe 10;

[0020] When using this tail gas collection device for a hydrochloric acid storage tank, as Figures 1-3As shown, hydrochloric acid can be injected into the main body 1 of the hydrochloric acid storage tank through the medicine unloading pipe 2 and the medicine unloading pump. When the liquid level of hydrochloric acid in the main body 1 of the hydrochloric acid storage tank is too high, the excess hydrochloric acid can enter the accident pool 9 through the overflow pipe 8, thus ensuring the normal storage of hydrochloric acid. During actual use, the hydrochloric acid in the main body 1 of the hydrochloric acid storage tank can be output for use through the dosing pump 3 and the dosing pipe 4. When hydrochloric acid is stored in the main body 1 of the hydrochloric acid storage tank, air can be conveyed into the main body 1 of the hydrochloric acid storage tank through the air pump and the air inlet pipe 5, so that the hydrochloric acid gas volatilized in the main body 1 of the hydrochloric acid storage tank can be quickly discharged outward through the air outlet pipe 6. With the functions of the intake one-way valve 501 and the outlet one-way valve 601, the gas in the main body 1 of the hydrochloric acid storage tank can be ensured to flow unidirectionally, thus facilitating the treatment of hydrochloric acid gas. Moreover, the gas discharged through the air outlet pipe 6 enters the neutralization medicine tank 7 through the air distributor 602 to react and neutralize with the neutralization agent. Through the function of the air distributor 602, the hydrochloric acid gas can be dispersed into small bubbles, thereby increasing the contact area between the hydrochloric acid gas and the neutralization agent in the neutralization medicine tank 7. And with the blocking function of the partition plate 701, the bubbles can flow to both sides, thus increasing the flow path length of the hydrochloric acid bubbles, and further effectively ensuring the collection and treatment effect of hydrochloric acid gas. This is the working principle of the tail gas collection device of this hydrochloric acid storage tank.
