Chinese patent CN206414962U discloses a smelting nitric acid smoke dust recovery device, wherein the top end inside a reaction kettle is communicated with a ventilator through a pipeline, the gas outlet of the ventilator is communicated with a spray passage through a pipeline, the top end inside the spray passage is provided with a fan-shaped spray header, the gas outlet of the spray passage is communicated with the bottom end inside a spray tower through a pipeline, the inside of the spray tower is sequentially provided with a first layer of spray header and a second layer of spray header from bottom to top, the top end inside the spray tower is communicated with an alkaline water tank through a pipeline, and the bottom parts of the spray passage and the spray tower are respectively communicated with a first liquid storage tank and a second liquid storage tank through pipelines; this smelt nitric acid smoke and dust recovery unit, waste gas purification rate is high, and the longer horizontal absorption of accomplishing in spray passage space, the spray column does not have the dead angle and accomplishes three-dimensional absorption, has partial noble metal in the nitric acid smoke and dust to be retrieved by activated carbon adsorption in liquid by the purification, avoids the metal to run off. This patent is the recovery processing that the alkali lye sprayed through the spray column realized the sour cigarette, and overall structure is comparatively huge, especially need adsorb out the sour cigarette and handle, this kind of device also is not applicable to this application sour cigarette handle the occasion, and the cost is higher.
Therefore, there is a high necessity for a device that can effectively prevent acid fume from escaping or acid fume from forming acid liquor dripping outside the pipeline and has low cost.
Disclosure of Invention
The utility model provides a device capable of recovering acid smoke, preventing the acid smoke from escaping into the atmosphere and preventing the acid smoke from escaping or dripping to hurt people.
The utility model is realized by adopting the following technical scheme: a sour tobacco recovery device comprises a top cap arranged above an outlet at the top of a sour tobacco pipeline, wherein the outer diameter of the top cap is gradually reduced from bottom to top, and the outer diameter of the bottom of the top cap can completely cover the outlet of the sour tobacco pipeline; an acid liquid funnel is arranged in the top cap, and the large opening of the acid liquid funnel is arranged upwards; the side wall of the acid liquid funnel is provided with a plurality of smoke holes, and the funnel hole at the bottom of the acid liquid funnel is over against the top outlet of the acid smoke pipeline.
In order to solve the problems that acid smoke at the smoke outlet of the acid storage tank volatilizes and forms diluted acid when water vapor in the air forms, the diluted acid drops on a human body to cause burn, and the acid smoke escapes into the atmosphere to cause environmental pollution, the utility model adopts the method of installing the acid smoke recovery device on the acid smoke pipeline of the nitric acid and sulfuric acid storage tank, thereby effectively preventing the acid smoke from escaping or dropping to hurt people.
The top cap structure helps to cover all the acid cigarettes, the acid cigarette can be collected by the acid liquid funnel, the acid cigarette reaching the inner wall of the top cap top is condensed and then drops downwards, and the acid cigarette is basically collected at the center of the acid liquid funnel due to the structure and the effect of the top cap and the acid liquid funnel, and flows back to the inside of the acid cigarette pipeline through the funnel hole.
The acid smoke recovery device is reasonable in structural design, can recover acid smoke and prevent the acid smoke from escaping into the atmosphere, has the advantages of being simple to install, low in cost, long in service life and convenient and fast to clean, and is suitable for various places where the acid smoke needs to be recovered.
Drawings
FIG. 1 is a schematic diagram of the structure of the present invention.
