System for cleaning of exhaust gases


(57) Abstract:

Usage: agriculture and engineering. The essence of the invention: in the path of the output exhaust installed ionizer, the output of which is communicated to the ozonizer. Ionizer and ozone generator are flaring discharge that allows the ionizer to play the role of the electrostatic precipitator and the second combustor soot and ozone to be the oxidant of sulphur and nitrogen compounds. 2 Il.

The invention relates to physical impacts on exhaust emissions, for example, heat engines for greenhouses and so on, and can be used in agriculture and engineering.

The known device for purification of exhaust gases, which include electrodes associated with high-grade and low-grade findings voltage source [1, 2]. When working with this kind of devices is the electrostatic deposition of solid particles. However, these designs are ineffective.

Closest to the claimed is a system that includes an ionizer to install in the path of the output of exhaust gases associated with unipolar high voltage source [3].

This system allows only ository could docility nitrogen and sulfur compounds and douche soot particles, passing through the ionizer.

However, due to the presence of corona electrostatic precipitator-ionizer such a system is not effective.

The aim of the present invention is to increase efficiency by not only complete afterburning of carbon black, but also the oxidation of nitrogen and sulfur compounds to the desired minimum level, while the precipitation of the solid particles of the exhaust gases, which is important when using such devices, for example, carbonated greenhouses.

This goal is achieved by the fact that the system is equipped with an ozone generator, the output of which is communicated with the output of the ionizer and connected to an appropriate source of unipolar high voltage, and the ozone and ionizer each made in the form of a cylindrical body, which has on its axis N-section of the Central electrode, where, N is 3 and each section has a view of two sides of an isosceles trapezium, coupled with its smaller base and installed along the entire length of the Central electrode, in this section mounted on the holder, having a cross-section view of the right 2N of a square with a gap between the sections at one side of it.

Searches conducted by the patent and scientific Prov. /P> Since the system is made of the known elements, it is claimed meets the criterion of "industrial applicability".

As well as the use of such a device would result in a new effect, which consists in the almost complete elimination of the emission of solid particles, reducing the level of nitrogen and sulphur compounds, the oxidation of soot, it is claimed meets the criterion of "inventive step".

In Fig. 1 is a schematic representation of the system of Fig. 2 - section a-a of Fig. 1.

The system includes the ionizer 1 associated with unipolar source 2 high voltage ozone generator 3, and it is also associated with source 2, but the power sources can be different. The ionizer 1 and the ozone generator 3 is made in the form of a housing 4, a low-potential electrode, but the electrode may be made separately and mounted on the inner wall of the housing, the high-potential electrode that is installed in the center of the housing and having N-section 5 in the form of long sides of an isosceles trapezoid associated with its smaller base and mounted on the holder 6, made for example of a dielectric which can play the role of a load resistance when applying to section 5 napryazhenii to have the fan 11.

The device mates with the exhaust pipe can be anything, but the system can also be mounted directly in the exhaust tract.

The system works as follows.

To the electrodes of the ozone generator 3 and the ionizer 1 is unipolar high voltage, in the particular case of the pulse. With candles 7 it comes in sections 5 and at their ends occurs flare discharge, in ionizer potential difference reaches 8 to 13 kV, the ozonizer 13-16 kV. With the passage of exhaust gases through the ionizer comes from the electrostatic filter and the ignition of soot due to the fact that the flare discharge not only charges the solid particles and form ozone, which contributes to the ignition. Further, the ozone from the ozonizer 3 getting 9 cooksley nitrogen compounds and sulfur to safe levels, after which the exhaust gases are ejected. When working in a hospital, for example, when the gassing of greenhouse carbon dioxide, for more efficient use of the fan. The holder 6 may play a role as additional resistance to a regime flare discharge, but can be made from a metal rod.

The use of this system allows you to effectively clean Wyhlen the information.

FIELD: agriculture, in particular, complex agricultural productions.

SUBSTANCE: method involves process and objects arranged in predetermined manner, and place planned according to relief, with geographic and other necessary factors being taken into consideration so that directions of natural air flows are corrected. Agricultural production includes complex greenhouses, heat accumulator, basin, garden, and wind shield. Air flow directed into garden is saturated with water vapors in gaseous state if increase in temperature is desirable when it is close to minimal admissible value, and in small droplet state when lower temperature is desirable. Processor functions as central controller. Objects of branches in agricultural production are selected so that objects of previous branches make raw material for objects of subsequent branches. Furthermore, joint mutually useful development of these objects at suitable conditions is possible. These conditions are created in complex greenhouse units intermediate with regard to said branches. General-purpose containers with raw material are conveyed through said complex greenhouse units. This results in multiple sequential-parallel utilization of raw materials in number of branches of industry. Method stipulates employment of useful relations between populations of organisms - objects of agricultural branches of industry: symbiosis and, according to kind of symbiosis, natural selection.

EFFECT: increased resource saving, reduced production costs of agricultural product and improved ecology of environment.
