DESCRIPTION

EQUIPMENT FOR EXHAUST GAS ABATEMENT IN THE

CLOSED PLACES

On behalf of VENTURELLA MATTEO

The present invention relates to a device and a process for reducing both the exhaust gases of cars in closed places, and the purification of the air during particular phases of work, especially in mechanical workshops when there is the need to keep the car turned on for maintenance or repairs or to extract the vapors deriving for example from welding, currently suction hoods are used that convey the gases outwards, with this invention it will be enough to convey the sucked air to the device without any connection with the outside or with flues. In a first aspect of the present invention, this object is achieved with a device for purifying the exhaust gases having the characteristics according to claim 1. Further characteristics of the device are the subject of the dependent claims.

In a particular embodiment, the apparatus is made up of a steel metal casing from which a tube exits and is connected to the machine drain. A suction motor conveys the exhaust fumes towards a closed circuit of PVC pipes filled with water, a second motor provides the right thrust to make the water circulate inside the circuit, to which a filter is connected. from a plastic tube of variable section containing expanded clay and a second activated carbon filter, the various pollutants transported by the water will be absorbed, returning purified air to the environment through a tube connected to a nozzle.

In a particular embodiment a sensor will warn by means of an indicator light when the water contained in the pipes will be dirty, at this point the circuit will be emptied through a drain cock, the water can be collected in a container or conveyed into the sewer.

The device can work either autonomously via a battery, connected to the mains, or in both ways.

The device lends itself to being made in small dimensions, with a height of 100 cm, a width of 70 cm and a depth of 45 cm with wheels at the base for easier mobility.

List of figures

These and other characteristics of the present invention will be made more evident by the description of the accompanying drawings in which like reference numbers always refer to like elements:

figure 1 shows the operation diagram of the apparatus;

figure 2 shows a front view of the apparatus finished and ready for use;

Detailed description

Referring to figure 1, this shows us the operating diagram of the apparatus (100) housed inside the steel casing 21 (figure 2), again with reference to figure 1 we have a suction motor 1 which will be connected the pipe 2 which will be positioned to the car exhaust, the fumes will be conveyed through the pipe 3 in the closed circuit of PVC pipes 4 filled with water, a second motor 5 will give the water the right push to make it circular in the pipes, connected to a filter 6 consisting of a variable section PVC pipe filled with expanded clay, through a diversion well 10 the water will continue to circulate in the circuit while the air will be directed towards a second filter 7 activated carbon, and will be able to exit through tube 8, which is no longer harmful. A sensor 9 connected to an indicator light 15 (figure 2) will warn when the now dirty water must be changed, through the drain 11 the circuit can be emptied, while from the pipe 12 it can be filled with clean water for a new cycle .

The apparatus for operation can be connected to the electrical network 13, or operate with a battery 14 positioned inside the casing or in both ways.

Figure 2 shows the complete apparatus 100 ready for use on the upper part the various switches for operation have been positioned, in particular switch 18 for switching on and off with the relative lights 19 , an ammeter 20 together with the warning light 16 will signal the battery charge, switch 17 is used to put the battery under charge, at the bottom comes the tube 2 which will be connected to the car exhaust.

The embodiments described above are susceptible of various modifications and variations without departing from the scope of the protection of the following invention.

Furthermore, all the details can be replaced by technically equivalent elements. For example, the materials used, as well as the dimensions, may be any according to the technical requirements.

The examples and lists of this application are intended as non-exhaustive lists.

Claims (3)

CLAIMS 1) The apparatus for the abatement of car exhaust gases in closed places (100) includes: a closed circuit of PVC pipes (3) filled with water, a filter consisting of a variable section PVC pipe (6) containing expanded clay, a second filter (7) with activated carbon. A motor (5) pushes the water into the circuit to ensure a continuous circulation, a second motor (1) connected to an external pipe (2) will suck the exhaust gases, through the pipe (3) they will be conveyed into the closed circuit of pipes (4) containing water. The sensor (9) through a warning light (15) will signal that the water must be replaced because it is dirty, the circuit is emptied from the drain (11) and filled with clean water from the tube (12). The battery (14) will be positioned inside the steel casing if it is not powered exclusively by the mains (13) if not by both. 2) The apparatus (100) according to claim 1 has a closed circuit of PVC pipes (3) filled with water kept in circulation with the right thrust by a motor (5) the exhaust gases transported by the water passes through a filter (6) consisting of a variable section PVC pipe filled with expanded clay. 3) The apparatus (100), again according to the previous claims, the water through a diversion well (10) will continue the circulation while the air will pass through a second filter (7) consisting of a PVC well containing activated carbon, and from the tube (8) it will be released into the environment now purified of harmful agents.
