Abstract

FIELD: cleaning air medium above roads in large towns with intensive traffic. SUBSTANCE: ducts are mounted at edges of road and are connected with fans and filters; power supply of fans is effected due to portion of shaft projecting beyond surface of road; this portion of shaft may be engageable with wheels of transport facilities; shaft is connected with generator of fan. Complex provides for cleaning the air from toxic admixtures at its own power supply source which may be also used as an emergency power supply source for some objects. EFFECT: enhanced efficiency of cleaning air. 3 dwg

Description

 The proposal relates to devices for improving environmental safety near transport highways. The offer can be used mainly in large cities with heavy traffic. The proposal has predominant use near intersections where a significant number of cars with running engines are accumulating, which leads to an intense accumulation of oxide and carbon monoxide, significantly exceeding the maximum permissible rate and the effect on surrounding residents in houses on both sides of the roadway, as well as on pedestrians accumulating at crossings at intersections.

 Gas analyzers are widely used by traffic police to determine the degree of environmental pollution by exhaust gases by installing them at the exhaust pipe and then adjusting the ignition and fuel supply system. For the definition of harmful constituents using a gas analyzer device, see, for example, Automatic devices, regulators and control machines. / Ed. Komarsky M.I. - M.: Mechanical Engineering, 1968, p. 228 and 229. Such an adjustment makes it possible to reduce carbon monoxide in the combustion products and, ideally, produce only carbon dioxide, but it is also a harmful poisonous gas to the body. Moreover, these components are contained in the combustion products of any energy carrier, which does not allow a coordinated solution to the problem.

 A closer device for design features and the achieved effect are technological processes for the chemical treatment of parts (Handbook of a metalworker. T. 3. - M .: Mechanical Engineering, pp. 123-135). Almost all parts for long-term use are coated either galvanically or with paintwork. This set of processes is used, for example, in the automotive industry (car factory ZIL, AZLK, FORD, etc.). The gas sources are equipped with ducts above the gas sources with pipelines and a fan with an energy source and filters.

The disadvantages of the known gas sampling devices include:
- energy costs from a centralized power supply network;
- the box covers the entire area of gas evolution, which cannot be used for transport routes.

The aim of the proposal is to address these shortcomings, namely:
- elimination of energy extraction from the general energy supply network;
- optimal placement of boxes to reduce gas contamination.

 This goal is achieved by the fact that the boxes are placed above the carriageway of the transport line along its edges in the zone of stopping traffic at traffic lights, and the power supply is made in the form of at least one shaft mounted perpendicular to the carriageway of the transport line and connected to the generator fan, and the shaft is placed in the gutter with a bias towards the drain line and protrudes beyond the upper surface of the transport line.

 In FIG. 1 is a cross-sectional view of a highway; in FIG. 2 - section along aa; in FIG. 3 - combined pneumoelectric circuit.

 The complex contains boxes 1 (3 boxes are shown: in the middle and along the edges of the carriageway). Boxes are made in the form of angular shapes with an angle that does not allow to be kept due to friction in the snow. Boxes 1 are fixed on pipelines 2 with openings 3 in the area of boxes 1. The ends of pipeline 2 are fixed on lighting poles or power racks of power lines 4. Pipeline 2 at racks 4 goes down and is connected to the fan 5 by one end and the other end is connected to the filter, which is made in the form of a curved part of the pipeline 6 in the drain line 7, and the end of the pipe 8 is located below the surface of the aquatic environment 9. On the roadway of the highway 10 in the groove 11, which has a slope 12 towards the drain line 13, is located a shaft 14 connected to the generator 15. The generators are connected to a distribution block 16 containing a buffer battery and a connection to a fan 5. The specified block 16 also has an output for selecting emergency power 17 for various purposes. Functionally, the unit 16 supplies constant voltage to the fan 5, and gives the surplus electricity either to the city network or to additional batteries for emergency use. Block 16 is not disclosed and can be performed in various ways (see Londi et al. Handbook of a radio engineer. Transl. From English. - M - L., 1961, section "Power Supplies", pp. 415-440). The dividing strip is conditionally shown by the protruding part 18, as well as the pedestrian - 19.

 The complex operates as follows. Fan 5 is constantly running if it is not forced off. The air flow passes through the pipe 2 and sucks in the air mass through the openings 3. The air mass is sucked in with exhaust gases, and the mixture enters through the bent end 6 of the pipeline, is bubbled through the aqueous medium, and purified air enters the atmosphere. Carbon monoxide and dioxide will form acids that are carried out by the water medium of the drain line 7. The power supply of the generators 15 comes from the rotation of the shafts 14 by passing cars, and when there are no passing cars, the power comes from the battery unit 16.

Notes on the use of the complex:
1. It is advisable to install the shafts on the slopes, so that the energy extraction from the vehicles is insignificant.

2. In summer, dirt and dust through gaps in the trough 11 will be washed off and through slopes 12 fall into the drain lines 13. Even with clogging, the force of the wheel with the surface of the shaft 14 will cause it to scroll. In winter, when the temperature is around 0 ^o C, the same process will occur. If the temperature drops sharply, then there will be no dirt, and there will be nothing to wash off. However, in difficult cases, washing with warm water is possible.

 3. Boxes 1 must be made transparent for sufficient illumination in the afternoon, in the summer.

 4. Along the duct, pipes with openings 3 can be installed so that the air mass is sucked in over a larger area.

 5. Boxes can be installed over the entire length of the possible length of the “plug”, and at the optimal length of the machines can be installed on the boxes 1 common transparent plate to increase the collection of exhaust gases.

 6. For residential buildings on the sides of the carriageway up to 15 floors, it is sufficient to have two side ducts, and for high-rise buildings - at least three.

 Thus, the goal is achieved: purification of air from harmful gases with its own power source, which is able to provide emergency power to any objects.
