The invention is further described below with reference to the drawings and examples.
Example 1
As shown in fig. 1, the air cleaning device for pharmaceutical industry of the present invention comprises a gas collecting hood 1, a dust-gas separation mechanism, and a gas cleaning mechanism. The gas collecting hoods 1 can be arranged on the crushing, screening and conveying equipment of the medicine raw materials and the semi-finished products respectively, so that the equipment which is easy to generate dust emission is produced in a closed state, and the leakage of dust is prevented. Each dust hood is respectively communicated with a dust-gas separation mechanism through a gas transmission branch pipe 2 and a gas transmission main pipe 3, the dust-gas separation mechanism is connected and communicated with a gas purification mechanism through a gas transmission pipe 11, and an exhaust fan 4 is arranged on the gas transmission main pipe 3. The dust-gas separation mechanism and the gas purification mechanism can be arranged inside a workshop or outside the workshop. The dust-gas separation mechanism is provided with a closed dust-gas separation container 7, the dust-gas separation container 7 is provided with a dust discharge port 5, an air outlet 10 communicated with the air transmission pipe 11 and an air inlet 6 communicated with the air transmission main pipe 3, and the air inlet 6 is positioned at the lower part of the dust-gas separation container 7. An atomizing nozzle 8a which is communicated with a high-pressure water pipe 9a is arranged in the dust-gas separation container 7. The atomizing nozzles 8a are provided in the upper middle portion of the dust-gas separation vessel 7, and may be provided in plural numbers, preferably 3 to 4. The gas purifying mechanism comprises a closed gas purifying container 12, wherein the gas purifying container 12 is provided with an exhaust pipe 13, a liquid discharge pipe 17 and an air inlet 16 communicated with the gas transmission pipe 11, and a liquid spray head 15 communicated with a high-pressure liquid transmission pipe 14 and used for spraying treatment liquid is arranged in the gas purifying container 12.
When the purification device of the present embodiment is used, the dust-containing gas generated in the production of each dust-prone equipment enters the dust-gas separation vessel 7 through the gas collecting hood 1, the gas delivery branch pipe 2, the gas delivery main pipe 3 and the gas inlet 6 and flows upward. The high-pressure air pipe 9a is started, water mist is sprayed out by the atomization spray head 8a and is mixed with upward flowing dust-containing gas, so that dust particles in the gas are moist and gravity is increased, the moist dust particles fall into a conical dust collection cavity at the lower part of the dust-gas separation container 7 by self gravity, and the dust particles are discharged from the dust discharge port 5 periodically or irregularly. Experiments show that more than 82% of dust in the dust-containing gas is separated after humidification and separation. The gas separated from the dust and gas is discharged from the gas outlet 10, enters the gas purifying container through the gas transmission pipe 11 and the gas inlet 16, and flows upwards through the gas purifying container 12. Simultaneously, the high-pressure liquid transmission pipe 13 is opened, a large amount of liquid sprayed by the spray header 15 washes all dust in the upward flowing gas into the treatment liquid, and the treatment liquid is discharged through the liquid discharge pipe 17; the purified gas may be discharged from the exhaust pipe 13.

A liquid storage container 20 can be arranged below the liquid discharge pipe 17 in the gas purification mechanism, the interior of the liquid storage container 20 is divided into a sedimentation chamber 20-2 and an overflow chamber 20-1 through an overflow baffle 21, mixed treatment liquid discharged by the liquid discharge pipe 17 is injected into the sedimentation chamber 20-2 for sedimentation, dust in the mixed treatment liquid is sedimented to the bottom of the sedimentation chamber 20-2 and can be cleaned regularly, and when the liquid level exceeds the overflow baffle 21, clarified treatment liquid at the upper part flows into the overflow chamber 20-1. The overflow chamber is communicated with the high-pressure liquid transmission pipe, and a booster pump is arranged on the high-pressure liquid transmission pipe. Thus, the treatment liquid can be recycled, and the consumption of the treatment liquid is reduced.
Example III
Referring to fig. 3, the atomizing nozzle 8b may be arranged in a vertically double layer, and the direction of inclination may be reversed. Thus, a better dust-gas separation effect can be obtained. The spray header 15 can be provided with an upper layer and a lower layer 2 so as to increase the spray density and obtain better purification effect. In addition, when toxic and harmful components are contained in the dust-containing gas to be purified, a certain amount of treating agent can be added into the treating liquid, and the treating agent can be neutralized by adopting an acidic or alkaline solution such as sulfuric acid, lime water and the like according to the characteristics of the toxic components so as to eliminate the toxicity in the purified gas and avoid the toxic pollution of the atmosphere environment.
