A tail gas pipeline that removes dust by generating electricity by itself

Abstract

The invention discloses an exhaust pipeline capable of removing dust by means of self power generation. The exhaust pipeline comprises electric wires, mounting supports, power generators, a rotary shaft, blades, power storage pipes and an exhaust pipeline body. The electric wires are wound on the blades, electric wire connectors are arranged in the rotary shaft, the blades are obliquely arranged on the outer side of the rotary shaft and encircle the rotary shaft by a circle, the power generators are arranged at two ends of the rotary shaft, the two ends of the rotary shaft are connected with rotary shafts of the power generators by couplings, the power storage pipes are provided with storage batteries, the power generators are connected with the power storage pipes, the power storage pipes are connected with the electric wire connectors in the rotary shaft, the rotary shaft is arranged in the exhaust pipeline body, the mounting supports are sleeved on bodies of the power generators, and the rotary shaft is mounted in the exhaust pipeline body via the mounting supports. The exhaust pipeline has the advantages that power generation assemblies are arranged in the pipeline body, the power generators are vertically mounted in the exhaust pipeline body, the blades are obliquely arranged, the electric wires are wound on the blades and are powered by the power generators, accordingly, static electricity can be generated on the blades, the dust can be sucked on the blades when exhaust flows through the blades, and the dust removal efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the field of automobile tail gas treatment, in particular to a tail gas pipeline for dust removal through self-generated power. Background technique [0002] With the continuous development of society, there are more and more cars. Because the exhaust pipes of automobiles will emit a large amount of exhaust gas, it will cause a lot of pollution. The treatment and reuse of exhaust gas has been put on the agenda. The traditional automobile exhaust dust removal device is to add a dust removal net to the end of the automobile pipeline for dust removal. The dust removal net is used to absorb the particles in the exhaust gas to reduce exhaust emissions, but its dust removal effect is very limited. It is well known that static electricity can absorb dust, so if the dust removal net is energized, the adsorption of the dust removal net can be greatly improved, but the power supply is required to power the dust removal net.

[0002] With the continuous development of society, there are more and more cars. Because the exhaust pipes of automobiles will emit a large amount of exhaust gas, it will cause a lot of pollution. The treatment and reuse of exhaust gas has been put on the agenda. The traditional automobile exhaust dust removal device is to add a dust removal net to the end of the automobile pipeline for dust removal. The dust removal net is used to absorb the particles in the exhaust gas to reduce exhaust emissions, but its dust removal effect is very limited. It is well known that static electricity can absorb dust, so if the dust removal net is energized, the adsorption of the dust removal net can be greatly improved, but the power supply is required to power the dust removal net. If you use the built-in power supply of the car, the circuit connection is very troublesome. If you use a separate power supply, the time is limited easy to cause waste

[0003] In fact, automobile exhaust itself can generate electricity. There are two main energy sources that can be used by automobile exhaust. One is thermal energy and the other is wind energy. Since the heat exchange generator is extremely complicated and the pipeline is small, if heat exchange is installed in the pipeline to generate electricity The machine cost is extremely high, and the heat exchange efficiency is low. However, if wind energy is used, although the structure of wind power generation is relatively simple and the technology is relatively mature, it is very difficult to install rotating blades in the exhaust pipe due to the extremely narrow wind power, and the wind power is limited. Part of the wind power will be wasted, so the utilization rate is low

[0004] Therefore, if the pipeline is not improved, it is not suitable to install a power generation device in the exhaust pipeline. Although the improvement of the pipeline is feasible, the cost is too high, and the power generation efficiency is lower if the pipeline is too large. Therefore, it is only possible to consider improving the generator. Currently used The blades of wind power generation equipment are set perpendicular to the main shaft, so the power generation equipment can only be perpendicular to the exhaust pipe, and the wind can drive the generator to rotate. Because the exhaust pipe is extremely narrow, the power generation equipment is also very small, not only the design cost is extremely high, and If the generator is installed vertically in the exhaust pipe, the ordinary small generator is used, but because the blades are parallel to the main shaft, the exhaust gas can hardly blow the generator to rotate, so it is necessary to set the blades obliquely to drive. Although the power generated is relatively limited, it is more than enough to charge the grid

[0005] Due to the general dust removal effect, the traditional dust removal net is installed at the end of the exhaust pipe, so the mesh is easily blocked and needs to be replaced irregularly. Due to the strong adsorption force after power on, the dust removal effect is excellent, and because the blades are inclined Around the motor shaft, so the wind passes through the blade and the blade has a large contact surface, and the grid is set on the blade, so the dust removal effect is excellent
