Detailed Description

The utility model is further described in detail below by means of the figures and examples. The features and advantages of the present utility model will become more apparent from the description. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model.

As shown in fig. 1 and 2, the embodiment of the utility model discloses an arsenic vapor condensing and collecting device, which comprises a tank body 1 for containing arsenic vapor, wherein the lower end of the tank body is provided with an arsenic vapor inlet 101, and the arsenic vapor inlet is connected with external equipment for generating the arsenic vapor. A condensation assembly 2 is provided in the tank 1, said condensation assembly comprising a condensation plate 201 and a support frame 202. The support frame and jar body fixed connection, when in actual use, can set up the number of piles of support frame according to the production scale, all be provided with the condensation plate at each layer of support frame. Arsenic vapor enters the tank body 1 from the arsenic vapor inlet, is condensed into arsenic solid simple substance after contacting the condensing plate 201, and can be further collected by taking out the condensing plate. The condensation plate 201 is movably connected with the supporting frame 202, for example, a chute can be arranged on the supporting frame, and the condensation plate is arranged in the chute, so that the condensation plate is convenient to take and place; bolts, snaps, and the like may also be used for connection. A cooling pipe 201-1 is provided in the condensation plate 201, and a cooling liquid flows through the cooling pipe. Specifically, referring to fig. 2, the cooling pipe 201-1 is spiral like a mosquito-repellent incense structure, and pipelines at the outer side position and the center position of the spiral extend to the outside of the tank body respectively to form a cooling liquid inlet and a cooling liquid outlet, both of which are connected with a cooling liquid circulation loop outside the tank body, and the type of cooling liquid can be selected according to actual requirements.

Preferably, each turn of the cooling tube 201-1 is spaced the same distance apart. Like this the cooling tube can be in the condensate plate evenly distributed, improves the utilization area of condensate plate, also helps improving the cooling effect.

Preferably, the arsenic vapor inlet 101 of the tank 1 is vertically offset from the installation position of the support 201. In particular, in the present embodiment, as shown in fig. 1, the arsenic vapor inlet 101 is provided below the right side of the illustrated tank 1, and the supporting frame 201 is fixed at the middle position of the tank. With this offset mounting, solid arsenic condensed on the condensing plate 201 is prevented from falling off into the arsenic vapor inlet.

Preferably, an exhaust gas outlet 102 is provided above the tank 1. The waste gas outlet is used for discharging waste gas which cannot be condensed in arsenic vapor, such as H ₂ O, HCl, and other minor low boiling impurities.

Preferably, the waste gas outlet 102 is located furthest from the arsenic vapor inlet 101 of the canister. Referring to fig. 1, in the present embodiment, the exhaust gas outlet is provided at a position on the upper left side of the figure of the tank, and the arsenic vapor inlet is provided at a position on the lower right side of the figure. Under the structure of the tank body in the figure, the distance between the waste gas outlet and the arsenic vapor inlet is the farthest, so that the flowing distance of the arsenic vapor can be prolonged, the condensing effect of the arsenic vapor is improved, and the arsenic vapor overflowed from the waste gas is reduced.

In summary, in the device for condensing and collecting arsenic vapor in this embodiment, the cooling pipe is disposed inside the condensing plate, so that the arsenic solids can be effectively prevented from condensing and adhering to the cooling pipe, and the arsenic solids only adhere to the surface of the condensing plate during the condensation process, thereby facilitating further collection.
