Description

AIR LIFT

The utility model relates to the field of environmental protection, in particular, can be used to clean polluted atmospheric air of cities.

A device is known (V.M. Gusev, Heat supply and ventilation. Leningrad: Stroyizdat, 1975, p. 193) for cleaning polluted air, consisting of a fan that takes polluted air from the production room and throws it out of the premises through ventilation pipes through special filters in which air is purified from suspended particles.

The disadvantage of this device is the inability to use it to clean the polluted atmosphere of cities due to the high energy intensity and fitness only for cleaning a limited space within the production room.

A device is known for reducing dust emissions into the environment (a.c.SSSR No. 836330 MKl Е04Н 12/28), adopted as a prototype.

The device is a chimney with diaphragms installed inside and with a central hole along the axis of which a corona electrode is passed.

The disadvantage of this chimney is the inability to use it for air purification of cities and high energy intensity.

To solve this problem, the air elevator, which is a vertical pipe channel with an open upper end and with slotted slots in the lower part, is equipped with filters and a wind power plant. Attached to the upper end of the channel, a wind power installation, creating rarefaction of air in a known manner (fans, heating, including stepped, etc.), enhances traction, thereby increasing the intensity of cleaning the atmosphere of the city. A diagram of the air elevator is shown in the drawing. The air elevator is a pipe channel I, in which filters for air purification 2 are placed, and a wind power installation 3 is installed on the upper open end of the channel 3. The pipe channel rests on the base 4, and slotted slots are made in the lower part of the channel. 5.

The air elevator works as follows: air from the surface layers of the pollution core formed over the territory of the city as a result of emissions of industrial products into the atmosphere, under the influence of draft generated in the pipe channel I of the air elevator, enters its lower end and ascends to the upper end, which positioned above the pollution core. In the process of ascending, air flows through filters 2 and are cleaned from products of industrial activity. As polluted air is taken from the surface layers of the atmosphere, clean air is drawn here from the upper layers of the atmosphere, as a result of which an artificial center of ventilation of the polluted air basin arises. To intensify the work of air elevators to create additional air pressure (vacuum), a wind turbine 3 is used, which can also be used to power filters operating on the electric principle, or to heat the air

at the base of the canal. Heated air inside the elevator using a wind turbine allows you to create traction with small fluctuations in the temperature of the atmosphere.

The calculation results presented in tables I and 2 show the viability of the proposed device. Heating the air inside the air elevator to 50 ° C makes the structure very productive, especially in winter (see table 1, columns 18 and 19). As can be seen from Table 2, the daily multiplicity of air exchange in the spatial volume of 5 km x 5 km x 0.5 km - 12.6 km3 can reach a dozen times.

The proposed air elevator operates continuously in automatic mode and requires only timely replacement or regeneration of filters.
