Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings, wherein the embodiments of the present invention are described in detail with reference to the accompanying drawings, for example, the shapes and structures of the respective members, the mutual positions and connection relationships between the respective portions, the functions and operation principles of the respective portions, and the like.
Example 1:
the embodiment provides an acid mist washing system, which can be connected with an acid storage tank to effectively intercept and absorb acid mist formed during acid discharge and acid mist volatilized at normal temperature, and reduce the influence on the surrounding environment.
As shown in fig. 2, the acid mist washing system of the embodiment includes a tower body 1, a vent hole 2 is arranged at the top of the tower body 1, an atomizing nozzle 3 and a washing nozzle 4 are sequentially arranged in the tower body 1 from top to bottom, a water storage tank 5 is arranged at the bottom of the tower body 1, and a mist guide pipe 6 for guiding acid mist is arranged between the water storage tank 5 and the washing nozzle 4 of the tower body 1; the atomizing nozzle 3 is connected with a tap water pipe 8 through an atomizing water pipe 7 and an atomizing nozzle valve 19, and the washing nozzle 4 is communicated with the water storage tank 5 through a washing water pipe 9 and a circulating pump 10.
The water storage pool 5 is connected with a tap water pipe 8 through a water replenishing pipe 11, the water replenishing pipe 11 is provided with a water replenishing control valve 12, the water replenishing control valve 12 is controlled by a time relay and is opened for a certain time (can be set according to needs) at a fixed time to replace water in the water storage pool 5, so that the phenomenon that the concentration of hydrochloric acid in water is too high to influence the adsorption and interception effects during circulation is avoided.
The water reservoir 5 is provided with an overflow pipe 13, and when the amount of water in the water reservoir 5 is excessive, the water can flow out of the washing tower through the overflow pipe 13.
As shown in fig. 3, in use, the mist guiding pipe 6 is connected to the breathing hole 16 of the acid storage tank 15, so that when the acid mist in the acid storage tank 15 escapes from the breathing hole 16, the acid mist is guided into the acid mist washing system by the mist guiding pipe 6. Can utilize atomizer 3 or washing nozzle 4 to spout water smoke downwards according to what of acid mist, utilize water smoke to keep off the acid mist, avoid acid mist to leak to the atmosphere and influence the environment. After the acid mist and the water mist are mixed, the acid mist drops downwards along with the water mist to the water storage pool 5 for temporary storage, and the acid concentration in the water storage pool 5 is low, so that the secondary volatilization of the acid mist can not be caused.
Specifically, as shown in fig. 4, after the acid storage tank 15 is connected to the hydrochloric acid tank car, the liquid inlet centrifugal pump 17 is opened, the hydrochloric acid in the hydrochloric acid tank car is pumped into the acid storage tank 15, and a large amount of acid mist is formed in the tank body due to impact rolling and the like. When the liquid inlet centrifugal pump 17 is opened, the circulating pump 10 is automatically opened, the washing spray head 4 and the atomizing spray head 3 jointly spray a large amount of water mist, and the acid mist entering the tower body 1 through the mist guide pipe 6 is blocked by the water mist and cannot volatilize to the atmosphere.
As shown in fig. 5, in a normal state, the atomizing head valve 19 is normally opened, and tap water forms water mist in the atomizing head 3 by the pressure of municipal tap water. Hydrochloric acid forms a small amount of acid mist in the acid storage tank 15 due to volatilization, enters the tower body 1 through the mist guide pipe 6, is blocked by water mist and cannot volatilize to the atmosphere. Because the daily volatile acid mist is less, the circulating pump 10 is not needed, and the water mist formed by tap water at the atomizing nozzle 3 can be intercepted, thereby achieving the purpose of energy saving.
When the liquid outlet centrifugal pump 18 is opened to extract the hydrochloric acid in the acid storage tank 15, air can enter from the vent hole 2 at the top of the washing tower and enter the acid storage tank 15 through the mist guide pipe 6 and the breathing hole 16, negative pressure cannot be formed in the acid storage tank 15, and the acid storage tank 15 cannot be deformed and damaged due to the negative pressure. As shown in fig. 5, the atomizing nozzle valve 19 is now open to prevent the acid mist from escaping into the atmosphere.
The present invention has been described in detail with reference to the accompanying drawings, and it is apparent that the present invention is not limited by the above embodiments, and various insubstantial improvements can be made without modification to the present invention.
