Description

A simple multi-stage water mist purification device

technical field

The utility model belongs to the field of environmental protection equipment, and relates to a water mist purification device for dedusting and deodorization, more specifically, to a simple multi-stage water mist purification device.

Background technique

There are a lot of dust in the air in spraying workshops, coal mine production sites, textile mills, flour mills, steel mills, etc. Dust is one of the five major disasters, which seriously endangers human health. According to relevant statistics from the Ministry of Health, there is pneumoconiosis in the country The total number of patients has reached 550,000, of which 130,000 have died, and the case fatality rate is 23.9%. Moreover, when the dust accumulates too much, it is very easy to cause an explosion, and there are potential safety hazards. Therefore, dust prevention is a key issue related to the safe production of enterprises. important link. At present, the commonly used air dust removal and purification equipment at home and abroad are mainly filter dust collectors, electrostatic precipitators and other equipment, but the above equipment has its own shortcomings:

The filter dust collector has a simple structure and is easy to use. However, the pore size of the filter material is small, the filtration resistance is large, the service life is short, and the filter element needs to be replaced frequently; when the humidity of the dusty gas is high, the dust is easy to stick to the filter material, which will block the filter material and reduce the dust removal performance.

The electrostatic precipitator is a dust removal device that ionizes the dust-containing gas in the process of passing through a high-voltage electric field to charge the dust particles. The electrostatic precipitator is characterized by small airflow resistance and low energy consumption, but ozone and nitrogen oxides may be generated during the dust removal process, resulting in more harmful secondary pollution.

There are many patents on filter dust collectors. For example, the Chinese patent application number is: 201510479161.8, and the publication date is: the patent document on November 11, 2015, which discloses a transfer point wet filter dust collector, including a spray dust collector and a centrifugal fan. One end of the spray dust collector is connected to the centrifugal fan, and the centrifugal fan is connected to the motor through transmission; the other end of the spray dust collector is connected to an elbow, and the connection between the elbow and the spray dust collector is provided with an air inlet gasket. The dust collector of this solution can effectively remove the coal ash on the belt transfer point, thereby reducing the content of coal ash in the air, thereby reducing potential safety hazards. At the same time, due to the all-inclusive design, the whole is cleaner and more hygienic, and the dust removal is more thorough. However, its structure is relatively complicated, and there are also problems mentioned above.

At present, in the air dust removal equipment, the use of water mist air dust collectors is more common. It uses water with lower pressure to spray water mist through small holes to absorb dust to purify the air. The water mist dust collector has the characteristics of simple structure, small footprint and high purification efficiency. The low-pressure water mist dust collector can effectively remove liquid or solid particles with a diameter greater than 10 μm in the airflow, and can also remove some gaseous pollutants. The purification efficiency is generally 80-90%. Regarding water mist air dust removal equipment, there are also many patents at present. For example, the Chinese patent application number is: 201310128862.8, and the publication date is: the patent document on October 15, 2014, which discloses a water mist dust collector, which includes a ring seam Type compressed air ejector, dust removal gland, water spray device, compressed air inlet, the side wall of the ejector is provided with an annular air chamber, and there is an annular gap between the dust removal gland and the air ejector, and the annular air chamber passes through the annular gap. The inner cavity of the ejector is connected, and the compressed air inlet is connected to the annular air chamber to introduce compressed air; while the water spray device is inserted into the dust removal gland and makes the water nozzle face the inner cavity of the ejector. The annular gap is located in front of the water nozzle. After the compressed air is introduced into the annular air chamber to expand, the high-speed airflow is ejected through the annular gap to form a negative pressure area. When the water supply valve is opened, the water flow and external air enter the negative pressure area, and the water enters the ejector of the high-speed airflow. The water mist is mixed with the air inside to form water mist, and the water mist absorbs dust to achieve the purpose of dust removal. However, it is mainly used in coal mine production sites, its scope of application is relatively limited, its structure is relatively complicated, and its manufacturing cost is relatively high.

To sum up, using the water mist dedusting method, how to reasonably design the structure of the dedusting equipment, not only make it easy to use, but also reduce its manufacturing cost, will be more conducive to its popularization and use.
