[0001] DESCRIPTION

[0002] SMOKE PURIFYING DEVICE

[0003] OBJECT OF THE INVENTION

[0004] The purpose of this invention application is to register a smoke purifying device that incorporates significant innovations and advantages over the techniques used to date.

[0005] More specifically, the invention proposes the development of a smoke purifying device, which, due to its particular arrangement, allows for adequate cleaning of the gases and fumes resulting from a specific combustion process, thus preventing harmful effects on the environment, and without the usual and cumbersome operations required by the personnel in charge.

[0006] BACKGROUND OF THE INVENTION

[0007] Different combustion processes are known in the current state of the art, which result in gases and fumes resulting from combustion.

[0008] These gases and fumes resulting from combustion contribute a large amount of harmful particles to the environment.

[0009] More specifically, in the state of the art, there are certain features, such as crematory ovens for funeral services, where the subsequent combustion is a major source of emissions of particles harmful to the environment.

[0010] In this regard, the elimination of suspended toxins in the fumes resulting from human incineration is mandatory in all furnaces that perform more than 800 incinerations per year. To achieve this, as is known in the state of the art, activated carbon (as a reagent) in powder form is introduced into a large device (bag filter) using an air suction system.

[0011] After this, 15 kg of this reactive powder is poured into a dosing device, for example, and mechanically released into the smoke ducts.

[0012] The continuous passage of these forced-air fumes creates an air current that is used to circulate and mix this reactive dust with the smoke, trapping and neutralizing toxic particles that should not be released into the air, as they would precipitate in the filter.

[0013] The granulometry of this flour-like powder product means that it can become compacted when it is dumped. This means that the personnel in charge must be constantly attentive to ensure proper operation by manually stirring the product, preventing it from compacting during dumping.

[0014] Furthermore, constant incidents and mechanical breakdowns are common due to the fact that the product's granulometry penetrates all internal mechanisms, causing constant blockages.

[0015] This means that if a blockage occurs during the cremation process, the resulting fumes will not be purified.

[0016] Handling this powdered product is therefore a cumbersome task requiring serious protective measures. It is often difficult to reconcile with an act such as incineration, which is highly formal and requires fully uniformed personnel. The present invention contributes to solving and resolving this problem, as it allows for adequate cleaning of the gases and fumes resulting from a specific combustion process before their release into the environment. Thanks to the use of capsule-like containers, the common problems of caking of the purifying product and mechanical incidents and breakdowns are avoided, greatly facilitating the work of the personnel involved and thus preventing harmful effects on the environment itself.

[0017] DESCRIPTION OF THE INVENTION

[0018] The present invention has been developed for the purpose of providing a smoke purifying device comprising an air circuit and control means, said circuit having an initial inlet of an air supply into the circuit and a final outlet following the path of the same circuit; in which along the same path of the circuit, after the initial inlet, the circuit incorporates a multiple valve, after which the same circuit is divided into a first subcircuit and a second subcircuit arranged in parallel; in which the first subcircuit comprises a pressure regulator, and the second subcircuit comprises a pressure dispenser and then means for inserting a powder purifying medium into the same second subcircuit; in which the control means are linked by data communication and capable of controlling the pressure regulator, the pressure dispenser and the means for inserting the purifying medium;in which the first subcircuit and the second subcircuit converge in their path after said insertion of the purifying medium from the insertion means and prior to the final exit of the circuit; in which the insertion means are enabled for insertion of the purifying medium from an individualized capsule-like container, in which said container previously contains a determined quantity of powder of the same purifying medium, and the same insertion means are also enabled for insertion of the powdered purifying medium from the same container or capsule to the subcircuit by means of an injection of air pressure from the pressure dispenser. Preferably, in the smoke purifying device, the control means are enabled for a timed activation and regulated and cyclical pulses of the pressure dispenser.

[0019] Alternatively, in the smoke purifying device, the second subcircuit incorporates a non-return valve in its path after the means for inserting the purifying medium.

[0020] Preferably, in the smoke purifying device, the circuit incorporates an air filter after the inlet and before the manifold valve.

[0021] Preferably, in the smoke purifying device, the circuit incorporates a pressure sensor after the filter.

[0022] Preferably, in the smoke purifying device, the purifying medium comprises powdered activated carbon.

[0023] Preferably, in the smoke purifying device, the circuit outlet is in communication with an evacuation of gases and smoke resulting from combustion.

[0028] Other features and advantages of the smoke purifying device will become apparent from the description of a preferred, but not exclusive, embodiment, which is illustrated by way of non-limiting example in the accompanying drawings, in which:

[0029] BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figure 1.- It is a schematic view of a preferred embodiment of the smoke purifying device of the present invention.

[0031] Figure 2.- It is a schematic view of a preferred embodiment of the smoke purifying device of the present invention and housed within a cabinet.

[0032] DESCRIPTION OF A PREFERRED EMBODIMENT

[0033] As schematically represented in Figure 1, the smoke purifying device of the present invention comprises a circuit 1 for conducting and passing air through it, with an initial inlet 2 of an air supply in the circuit 1 and a final air outlet 3 of said circuit 1 following the route of the same circuit 1.

[0034] In this preferred embodiment, the smoke purifying device of the present invention has a pneumatic operation, with air supplied to inlet 2 of circuit 1 by means of compressed air. In this preferred embodiment, circuit 1 incorporates an air drying filter 13 after inlet 2 to eliminate impurities in the supplied air, and also a pressure sensor 14 or pressure switch after filter 13, in order to verify that the air supply pressure at inlet 2 is adequate.

[0035] As can be seen in Figure 1, after the filter 13, the circuit 1 incorporates a multiple valve 4, after which the same circuit 1 is divided into a first subcircuit 11 and a second subcircuit 12 arranged mutually in parallel.

[0036] The first subcircuit 11 comprises a pressure regulator 5, and the second subcircuit 12 comprises a pressure dosing device 6 and then means 7 for inserting a purifying medium into the same second subcircuit 12.

[0037] In this described embodiment of the smoke purifying device of the invention, the purifying medium comprises powdered activated carbon.

[0038] Furthermore, in the smoke purifying device of the invention, the means 7 for inserting powdered activated carbon are enabled for inserting the powdered activated carbon from an individual capsule-like container.

[0039] Said container or capsule can be manually inserted into the same insertion means 7. The capsule previously contains a determined and rated quantity of powdered activated carbon, for example 300 gr.

[0040] The same insertion means 7 are also enabled for insertion of the powdered activated carbon from the capsule to the subcircuit 12, by means of an injection of air pressure from the pressure dispenser 6.

[0041] As can also be seen schematically in Figure 1, the first subcircuit 11 and the second subcircuit 12 converge in their path after said insertion of the activated carbon, and prior to the final output 3 of the circuit 1. Also in this described embodiment of the smoke purifying device of the invention, the second subcircuit 12 incorporates a non-return valve 9 after the insertion means 7.

[0042] Because the powdered activated carbon container capsule contains a specific rated weight of powdered activated carbon, the flow of powdered activated carbon to subcircuit 12 does not occur continuously, but discretely, according to predetermined, rated weight values ​​of the powdered activated carbon contained in the capsule. These predetermined rated weight values ​​of powdered activated carbon are appropriate for different usage needs.

[0043] Furthermore, the smoke purifying device of the invention also comprises control means 10, for example a micro-PLC.

[0044] Said control means 10 are linked in data communication, and also with control capacity, over the pressure regulator 5, the pressure dosing device 6 and the insertion means 7 for the insertion of activated carbon.

[0045] The control means 10 govern the operation of the pressure proportioner 6, and activate the same pressure proportioner 6.

[0046] When the pressure dispenser 6 is activated by a pulse, the same regulated pressure pulse then reaches the insertion means 7, which, thanks to the action of said pressure pulse, allow the discrete quantity of powdered activated carbon to pass through and exist in the capsule, already referred to above, which is then introduced into the second subcircuit 12.

[0047] The control means 10 also exercise control over the pressure regulator 5 of the first subcircuit 11, in order to provide the first subcircuit 11 with an adequate pressure in the path of the air through it and at its confluence with the second subcircuit 12.

[0048] After the confluence of the first subcircuit 11 and the second subcircuit 12, the dosed activated carbon continues to be driven by the pressure received from the pressure regulator 5 of the first subcircuit 11, to the outlet 3 of the circuit 1.

[0049] In this preferred embodiment, the amount of activated carbon previously present in the capsule therefore represents a dosage of 300 grams of powdered activated carbon.

[0050] Outlet 3 of circuit 1 is in communication with a duct 20 for the evacuation of gases and smoke resulting from combustion in a funeral crematorium, so that the activated carbon dosed from the smoke purifying device of the invention can carry out a cleaning of those harmful particles resulting from the combustion of the same crematorium and prior to their exit into the surrounding environment.

[0051] As can be seen in Figures 1 and 2, the smoke purifying device of the invention can be housed and also operated inside a cabinet 30, with its outlet 3 facing outwards. In Figure 1, the cabinet 30 is shown transparent so that the constitutive arrangement of the smoke purifying device of the invention can be appreciated.

[0052] The smoke purifying device of the proposed invention is specifically designed for purifying gases and smoke resulting from combustion, especially in the case of funeral-type crematory ovens.

[0053] This allows the dosed activated carbon to undergo a chemical reaction in the gases and fumes resulting from combustion, which cleans all impurities harmful to the environment before they are discharged through a furnace chimney.

[0054] The smoke purifying device of the invention offers the important advantage of using capsule-like containers for a measured and determined dosage of the powder purifying product.

[0055] This avoids the usual problems of caking of the purifying product and the frequent incidents and mechanical breakdowns, making the work of the personnel involved extremely easier, since handling this powdered product would be cumbersome and difficult to reconcile with an event such as incineration, which is supposed to be highly formal and where the personnel involved are fully uniformed.

[0056] The details, shapes, dimensions and other accessory elements, as well as the materials used in the manufacture of the smoke purifying device of the invention, may be conveniently replaced by others that are technically equivalent and do not deviate from the essence of the invention or the scope defined by the claims included below.
