DESCRIPTION

APPARATUS FOR AIR PURIFICATION

IN CLOSED PLACES

The present invention relates to a device and a process for purifying the air inside closed rooms, especially in all those rooms where a direct exchange with the outside is not possible, the air will be treated by the this device without having to be connected to flues.

In a first aspect of the present invention, this object is achieved with a device for purifying the air 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 consists of a fan that sucks the air inside the room and conveys it to a closed circuit of pipes filled with water, passing through a manifold to which they are connected three PVC pipes containing clay, the air undergoes a first treatment then through a distribution well it passes through a second filter consisting of a container with a steel grid inside, a layer of activated carbon and a second grid always in steel on which a transparent glass tube rests, with a lamp inside consisting of an ultraviolet fluorescent tube that will further purify the air introduced into the environment.

An engine will circulate the water inside the closed circuit with the right thrust, a sensor will warn when the water contained in the pipes will be replaced because it is dirty, at this point the circuit will be emptied and the water will drain in the drain pipe connected to the sewerage network, then the water inlet pipe will feed the circuit with clean water, both managed by solenoid valves, the device must be connected to the electricity network.

The dimensions can vary according to the quantity of air to be treated.

To ensure correct air exchange in places where there are no windows or where direct exchange with the outside is not possible, a fan will suck air from the outside, a solenoid valve will regulate these inputs, the air it will enter the circuit for treatment.

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:

Detailed description

Referring to figure 1, this shows us the operating diagram of the apparatus (100), consisting of a closed circuit of PVC pipes 14 containing water. The fan 1 sucks the air inside the room, the pipe 2 sends to a manifold 3 to which three PVC pipes 4 with variable section filled with clay are connected, through the manifold 5 the mixture of water and air arrives to the distribution well 6 connected by the pipe circuit 14 to a second filtering system 7 consisting of a container with a perforated steel grid 8 inside a layer of activated carbon 9 a second perforated steel grid 10 a steel tube transparent glass 11, with a lamp inside consisting of an ultraviolet fluorescent tube 12, through the tube 13 the air will be introduced into the purified environment.

The motor 18 powered by the mains 22 gives the water the right push to make it circulate inside the closed circuit, the float 17 will control the level, the sensor 23 will warn when the water needs to be changed, by means of the pipe 16 controlled by valve 19 the circuit will be emptied into the sewer, from pipe 15 connected to the water mains, through valve 20 the circuit can be filled again with clean water.

If necessary, air will be sucked in from the outside to ensure a correct exchange of air in places where there cannot be a direct exchange with the outside through the fan 21 a valve 25 will regulate this flow and from the tube 24 the ™ air will enter the treatment circuit.

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 (2)

CLAIMS 1) The apparatus for purifying the air in closed places (100) includes: a closed circuit of PVC pipes (14) filled with water, a fan (1) sucks in the air from the environment and through the pipe (2) sends it to the manifold (3) which conveys it into the filters ( 4) made of PVC pipes with variable section containing clay. From the manifold (5) the mixture of air and water reaches a distribution well (6) and then passes through a second filter consisting of a container (7) with a perforated steel grid (8) inside, a layer activated carbon (9), a second perforated steel grid (10) a transparent glass tube (11) a lamp consisting of an ultraviolet fluorescent tube (12), a float (17) that controls the level of Water inside the circuit, from the tube (13) the air is introduced into the purified environment. The water loading and unloading inside the circuit takes place through the two pipes (15) filling and (16) unloading controlled by solenoid valves (20) and (19). A motor (18) powered by the mains (22) will give the water the right boost to make it circulate inside the circuit. The fan (21) will suck air from the outside, regulated by the valve (25) and from the tube (24) it will enter the circuit for the treatment. 2) The apparatus (100) according to claim 1 has a closed circuit of PVC pipes (14) filled with water through the pipe (15) connected to the water mains, the opening and closing is controlled by the valve (20). When the sensor (23) signals that the water is dirty, the circuit can be emptied through the pipe (16) connected to the sewer and controlled by the valve (19) for closing and opening. The water will be kept in circulation with the right thrust by a motor (18) powered by the electricity network.
