Description

The invention relates to non-electric lighting devices with a light source that does not contain paraffin, fats, wax or oil of oil, which are used indoors, in particular in churches and temples when conducting services.

The products of the burning of candles and lamp oil are the cause of intense pollution of the interiors of the premises. This problem is most relevant for the preservation of icons, wall paintings and carved decor, which are of artistic value and monuments of cultural heritage. During the sorption of products of incomplete combustion of paraffin and wax candles and lamp oil for a long period of time, a soot layer forms on the surface of the walls, icons and interior elements, leading to irreversible damage to objects of artistic, cultural and historical value.

As a result of the studies, it was found that with limited access to indoor air, products of incomplete combustion are formed in large quantities, rise up in the stream of warm air, and then deposited on interior elements, mostly on cold and damp surfaces. Products of incomplete combustion include solid fine particles and gaseous components. The composition of soot includes carbon black (soot) up to 90 mass. % and hydrocarbon fraction from products of thermal degradation of paraffins containing more than 30 chemical compounds. In the studied samples, the presence of the products of burning candles and lamp oil was found, which cause the destruction of the binder mural and soil (Belyaevskaya ON, Fomin I.V. Contamination of the interiors of churches with products of burning candles // TOR-IF.RU: website of Engineering Firm LLC “TOP”. 2017. URL: http://www.tor-if.ru/new_page_mart2013.htm (accessed: 05.22.2017).

A high concentration of harmful substances in the products of incomplete combustion of paraffin, wax and oil of oil can lead to pulmonary and respiratory diseases among parishioners, clergy and clergy who have been in churches and temples for a long time during services. To eliminate these problems, electric light sources can be used, however, this approach does not always comply with the traditions and canons of services in churches and temples of various faiths.

It is known to use alcohols as a combustible substance in wicks. In the international application WO 2012/112895 A1 (publ. 23.08.2012) describes a wick lighting and heating device comprising a container formed by an axisymmetric shape housing that is filled with a liquid combustible substance. A mixture of glycols (dihydric alcohols, diols) is used as a combustible substance. A mixture of monoethylene glycol with diethylene glycol and other alcohols, including methanol and ethanol, is preferably used. The wick is partially placed in a liquid combustible substance and provides the supply of combustible substance to the combustion area due to the capillary effect, while the open surface of the liquid filling the container interacts with the surrounding air. The design of such a device is more adapted to operate as a heater than a light source. It should be noted that ethylene glycol couples are toxic and pose a hazard with prolonged inhalation. In compounds with air, ethylene glycol vapors are explosive, therefore, in practice an aqueous solution of ethylene glycol with a water content of at least 15% is used. In this case, the combustion efficiency of these combustible substances is reduced.

The supply of liquid combustible material to the area of combustion of the flame in the known device is carried out through a wick made of fiberglass, which is in direct contact with the combustible substance. The content of methanol and ethanol in the combustible mixture of glycols is 15 and 6 masses, respectively. % By design, this device is an alcohol heating burner. The choice of a combustible substance in a known device is determined by the required combustion temperature of the working substance in the air.

Other designs of devices of a similar type are also known. So, for example, in the patent for utility model CN 2932097 U (publ. 08.08.2007) the design of a light source containing a container filled with a liquid combustible substance, which is used as diethylene glycol or monoethylene glycol, is disclosed. The exposed part of the wick having a fibrous structure is protected by a perforated metal cover. Using a perforated protective cap, the evaporation of toxic flammable liquid into the surrounding air is reduced. Moreover, due to the use of alcohol as a fuel, instead of hard paraffin, the formation of soot (soot) is eliminated and the complete combustion of the fuel in the air is ensured.

In the international application WO 87/03064 A1 (publ. 05.21.1987) describes the design of the power supply system of several light sources (candles or lamps) with a liquid combustible substance. Each light source is formed by a wick with a fibrous structure, the lower part of which is fixed on the bottom of a common reservoir (tank) filled with liquid combustible substance. Holes for individual light sources are made in the upper part of the tank, and recesses for fixing the wicks on the bottom located opposite the upper holes are made in the lower part. Vertically oriented tubes are installed in the holes and recesses, each of which forms the body of a separate light source. Wicks made of fibrous material are located in the tube cavities, connecting the open end part of the tube with the lower part of the tube communicated with a corresponding recess on the bottom of the tank. Using the piping system, the recesses in the bottom of the tank are filled with liquid combustible material supplied from an external container. Due to the action of the capillary effect, the combustible liquid rises up from the recesses to the open part of the wick in contact with the air of the surrounding space, where the ignition and combustion of the working substance occurs. The fuel supply in each light source is determined by the volume of recesses made in the bottom of the tank. A drain pipe connected to the tank avoids overfilling of the recesses with a liquid combustible substance.

This device can be used as an alternative to the design of candles with a solid paraffin-containing combustible substance. Using a common tank (container), one or several closely spaced light sources are powered. However, such a device can only be used as a stationary non-portable device, since it does not have the technical means that ensure the retention of liquid combustible matter in the recess of the tank when its spatial position changes.

The closest analogue of the invention is a light source (candle), described in patent for invention RU 2602600 C1 (published on November 20, 2016). The device is a cylindrical container of fibrous material impregnated with a melt of a fatty substance (paraffin), with a wick. The device can be used as a portable light source, but the use of paraffin as a fuel determines the occurrence of the above problems associated with incomplete combustion of paraffin in the air and, as a result, the intense formation of soot (soot) on surrounding objects and surfaces of the interior and walls of rooms.

The invention is aimed at eliminating from the composition of the combustible substance components leading to the intensive formation of products of incomplete combustion, including soot, and to providing conditions for the stable supply of liquid combustible substances into the combustion zone and retaining them in the container when changing the spatial position of the candle. Under these conditions, the device can be used as a stationary or portable light source.

Solved technical problems associated with the incomplete combustion of combustible materials such as wax, paraffin and lamp oil. Products of incomplete combustion of combustible materials in the form of soot (soot) are deposited on the surface of surrounding objects, interior elements and surfaces of walls of premises. At the same time, the space of the premises is contaminated with finely dispersed carbon particles hazardous to human health, which are formed when paraffin, wax or oil of oil is incompletely burned in the air. Previous attempts to replace these flammable substances with dihydric alcohols (glycols) have not led to the creation of portable non-electric light sources that look like wax candles or lamps, traditionally used in services in churches and temples.

When carrying out the invention, the following technical results are achieved: the most complete combustion of a combustible substance in air is ensured; the liquid combustible substance is held in the container when the device is moved and the working substance is stably supplied from the container to the open part of the wick - into the flame combustion zone. The stability of the supply of combustible material and the stability of the burning of the flame is ensured by changing the spatial position of the candle. Due to the implementation of these conditions, soot formation on surrounding objects, interior elements and walls of the premises is eliminated and the possibility of air pollution by hazardous products of incomplete combustion of paraffin, wax or lamp oil is excluded. Using the invention, it is possible to use a non-electric light source as a portable candle or lamp when conducting services in churches and temples.

The above results are achieved through the use of a non-electric light source that can be transferred and its spatial position can be changed without disturbing the supply of flame with a combustible substance. The portable device comprises a container made of a material with a capillary fibrous structure and filled with a liquid combustible substance impregnating the fibrous structure of the container, and a wick with a fibrous structure.

According to the invention, the light source comprises a housing with an internal channel and an end wall separating the channel cavity from the surrounding air. The device includes a cover with an axial hole, which is installed on the open part of the channel. The container of the candle is located in the cavity of the channel of the housing and is also made with an axial hole. The candle wick passes through the axial hole of the lid and the axial hole of the container. Container fibers are oriented along the wick. An essential condition for the interdependent choice of the material of the fibrous structure of the container and the liquid combustible substance is the condition according to which the material of the container must be wetted by the liquid combustible substance.

One of the following substances is used as a combustible substance: monohydric alcohol, a mixture of monohydric alcohols, a carbonyl compound, a mixture of carbonyl compounds, a mixture of alcohol and a carbonyl compound. The main feature of the above liquid combustible substances are the same reaction products of the complete combustion of organic compounds in oxygen.

Monohydric alcohols include organic compounds containing OH hydroxyl group, while in them only one hydrogen atom is replaced by a hydroxyl group. Carbonyl compounds include organic compounds whose molecules contain a carbonyl group C = O. Depending on the nature of the substituents bonded to the carbonyl group, carbonyl compounds are divided into aldehydes, ketones, carboxylic acids and their functional derivatives. When these organic compounds are burned in atmospheric oxygen, they burn almost completely, without forming soot (soot) and smoke.

This effect is due to the fact that monohydric alcohols and carbonyl compounds ignite and burn in oxygen, forming terminal oxidation products: carbon dioxide (carbon dioxide) and water. The most intense combustion reaction of monohydric alcohols and carbonyl compounds occurs in an atmosphere of pure oxygen. It is preferable to use ethyl or methyl alcohol or a mixture thereof as monohydric alcohols, and acetone, which is the simplest representative of saturated ketones, as carbonyl compounds.

In the construction of the light source according to the invention, the liquid combustible as a result of the capillary effect flows from the container along the fibers to the open part of the wick, which also has a fibrous capillary structure. Due to the action of the capillary effect, the open part of the wick in contact with the surrounding air is constantly fed with liquid combustible substance from the volume of the container. When the spatial position of the candle changes, for example, when moving it or tilting it relative to the vertical direction, the wick does not spill or interrupt the power supply of the liquid fuel to the wick, since the liquid is held in the capillary structure of the container between fibers oriented in a certain direction along the wick. Under these conditions, the capillary channels between the fibers are also predominantly oriented along the wick.

In a preferred embodiment of the device, the wick is located coaxially with the common axis of symmetry of the housing, the channel made in the housing, the lid and the container, the fibers of the container being oriented parallel to the common axis of symmetry of the structural elements of the device. In this case, the housing has an axisymmetric shape. The device can simulate a wax candle; for this, a coating simulating the surface of a wax candle is applied to the outer surface of the body. When the device performs the function of the lamp, the body of the light source will repeat the shape of the container of the lamp.

A container filled with liquid combustible material is located in a closed volume limited by the walls of the housing and a lid mounted on the open part of the channel. Thus, the cavity with the container filled with liquid combustible material is separated from the surrounding air from all sides, with the exception of the hole in the lid through which the wick passes. To prevent evaporation of the combustible substance in the inoperative state of the light source through the longitudinal capillary channels formed in the fibrous structure of the wick, a removable protective cap is used, which is installed on the upper end part of the housing. A sealed cap separates part of the channel with the lid from the surrounding air.

Part of the wick can be located between the end wall of the housing and the end part of the container. In this case, the liquid from the container to the upper open part of the wick comes from the side of the lower part of the wick in contact with the end part of the container and, accordingly, with the open end parts of the longitudinal capillary channels. In addition, the lower part of the wick fixes the position of the container in the cavity of the channel of the housing. To exclude contact of the container and capillary channels with the walls of the housing and wetting the surface of the walls, the container is installed in the cavity of the channel of the housing with the formation of gaps relative to the walls of the housing.

The material of the container fibers is preferably nylon, lavsan and other artificial fibers wetted with a liquid combustible substance.

To create a pleasant burning odor, a combustible substance may include at least one flavoring component (additive). A certain color of the flame can be achieved by including at least one component in the composition of the combustible substance that affects the color of the flame when the candle is burning. As such a component, sodium salts, for example, chloride or sodium carbonate, which color the flame in yellow-orange color, can be used.

The combination of the possibility of using liquid combustible substances that do not form incomplete combustion products in the form of smoke and smoke when burning in air and the possibility of continuous stable supply of a candle wick with a combustible substance when changing the spatial position of the candle allows the use of a portable non-electric light source as an environmentally friendly candle or lamp, which are used when conducting services in churches and temples of various faiths. Moreover, the internal cavity of the device housing in which the container is installed is not filled with liquid combustible substance, since it is completely absorbed by the capillary fiber structure of the container. In this case, the possibility of overflow and spill of liquid combustible material from the cavity of the candle body is excluded.

The invention is further explained in the description of a specific example of its implementation. The accompanying drawing schematically shows a longitudinal section of a portable light source that performs the function of a wax candle.

The light source, made in the form of a burner, contains a cylindrical housing 1 (in the form of a candle) with an internal coaxial cylindrical channel 2. The end wall of the housing 1, which separates the cavity of the channel 2 from one side of the external (surrounding) environment, is formed by a removable end cap 3. In this example, the housing 1 is made of fiberglass, and the plug 3 is made of brass. On the outer surface of the housing 1 is applied a decorative coating that simulates the appearance (outer surface) of a wax candle. In the cavity of the channel 2 is placed a container 4, also having a cylindrical shape and made of a material with a fibrous structure. The fibers of the container 4 form interconnected capillary channels. The container 4 is located in the cavity of the housing 1 with the formation of a gap relative to the lateral annular wall of the housing.

The container 4 is filled with a liquid combustible substance, for which, in this example, a mixture of monohydroxy alcohol, in particular ethyl alcohol, with additional components: flavoring and coloring, is used. As a flavoring component, a food flavoring identical to natural is used, “Flower honey” (honey 536), which has a pleasant odor, in an amount of from 0.075 to 0.09 mass. % As a component that affects the color of the flame, sodium chloride is used in an amount of from 0.05 to 0.1 mass. %

The fibers of the container 4 are made of nylon wetted with ethyl alcohol. Due to the wetting of the fibers of the container, ethyl alcohol impregnates the fibrous structure of the container 4 and fills the capillary channels formed by the fibers without forming a liquid phase in the channel 2 and outside the container. In this construction example, in the gap between the outer surface of the container 4 and the walls of the housing 1, a liquid phase of a combustible substance is not formed.

The container 4 is made with an axial channel. A removable cover 5 made of brass is mounted on the open end of the channel 2. An axial hole is formed in the lid 5 located coaxially to the axial channel of the container 4. The candle uses a wick 6 made of fiberglass with a capillary fiber structure. In this example, the wick 6 is aligned with the common axis of symmetry of the housing 1, channel 2, lid 5 and container 4. The fibers of the container 4 are oriented along the wick 6 and parallel to the common axis of symmetry of the above structural elements.

The wick 6 passes through the axial hole of the lid 5 and the axial channel of the container 4. The lower portion 7 of the wick is located between the end wall of the housing formed by the plug 3 and the lower end of the container 4. The upper portion 8 of the wick, the length of which is less than the length of the lower portion 7, forms an open part of the wick in contact with the burning candle with ambient air.

The composition of the candle also includes a removable protective cap 10, which is removed before lighting the candle. In the inoperative state of the candle, the cap 10 is installed on the end part of the housing 1 and separates the open part of the channel 2 with the cover 5 from the surrounding air.

In another embodiment of the design of the device, its body is made in the form of a lamp, while the remaining structural elements remain unchanged. The lamp housing can have a different axisymmetric shape, for example spherical, conical or complex, consisting of sections of various forming surfaces. As the liquid combustible substance, another monohydroxy alcohol, for example methyl alcohol, or a mixture of ethyl and methyl alcohols can be used. In other embodiments, carbonyl compounds, for example aldehydes and ketones, or a mixture of aldehydes and ketones, or a mixture of carbonyl compounds with alcohols, can be used as a liquid combustible substance. Most preferably, the effectiveness of the use of the simplest representative of saturated ketones - acetone. In a mixture with methyl alcohol, acetone (40 wt.%) Forms acetone alcohol. Propanal, an aldehyde of propionic acid, which is an isomer of acetone, can be used as a combustible substance.

Examples of the implementation of the invention are possible, including the use of other substances as additional components of a combustible liquid: lavender extract, as a flavoring component, in an amount of from 0.075 to 0.09 mass. % and sodium bicarbonate, as a coloring component (affecting the color of the flame), in an amount of from 0.05 to 0.1 mass. %

The work of the light source used as a candle is as follows.

Before using the device, the container 4 with the wick 6 passing through the axial channel of the container 4 is completely filled (impregnated) with ethanol due to the wetting effect of nylon fibers forming the capillary structure of the container. The filled container is placed in the cavity of the channel 2, while the long lower section 7 of the wick is located on the installation side of the plug 3, and the short upper section 8 is located on the side of the cover 5. The plug 3 is screwed into the housing 1, forming the end wall of the housing 1. Between the end wall and the opposite end part of the container 4 fits the long lower section 7 of the wick.

The short upper section 8 of the wick is passed through the axial hole of the cover 5, forming the open part of the wick, while the removable cover 5 itself is installed on the open part of the channel 2. In the fixed working position, the container 4 is placed in a closed volume limited by the walls of the housing 1, the plug 3 and the cover 5. In the idle state, when the candle is not lit, a removable protective cap 9 is installed on the upper end part of the housing 1, separating the open part of the channel 2 with the cover 5 and the open part of the wick 6 from the surrounding air s. By sealing the channel 2, in which the container 4 filled with liquid is installed, unproductive losses of liquid combustible material due to its evaporation through the open part of the wick 6 are eliminated. In the case of using liquid combustible substances whose vapors are toxic, for example methyl alcohol or acetone, sealing open part of the wick 6 with a protective cap 9, prevents pollution of the surrounding air environment near the light source by vapors of toxic substances. In the operational state of the device (during the burning of a candle or lamp), such pollution is eliminated due to the complete combustion of liquid combustible substances in oxygen.

Before lighting the candles, it is necessary to remove the removable protective cap 9 from the housing 1, after which you can light the candle (light source). Due to the use of sodium chloride in the composition of the liquid combustible substance, the candle flame during combustion of ethanol vapor in the air has a yellow-orange color. If the composition of the combustible substance does not contain components that affect the color of the flame (coloring components), then the flame of ethanol combustion in the air will be dimly bluish. With an increase in the molecular weight of monohydric alcohol, the luminosity of the flame increases when it burns in air.

When a flavoring component is used in the composition of a combustible substance, in the considered example of a food honey flavoring identical to natural, a pleasant and soothing smell is formed in the surrounding air space.

In the process of burning a candle, a continuous supply of liquid combustible material to the open part of the upper portion 8 of the wick is carried out due to the capillary effect in the channels formed between the nylon fibers of the fibrous structure of the container 4. Due to the fact that the fibers are oriented along the wick 6, parallel to the common axis of symmetry structural elements of the device, with the consumption of alcohol through the open part of the wick, the redistribution of the stock of working fuel in the container 4 occurs.

The pressure drop in the container below the pressure of the saturated vapor of the liquid as a result of the combustion of part of the combustible substance in the open part of the upper portion 8 of the wick leads to the partial evaporation of the liquid filling the container 4. Due to the evaporation of the combustible liquid, the pressure of the gaseous substance filling the channel 2 increases. displacing the liquid from the container 4 through the capillary channels to the open part of the wick, through which intense mass transfer occurs during the combustion of the working substance. As a result of the capillary effect, the working substance is directed not only to the upper portion 8 of the wick, but also to the lower portion 7 of the wick, which feeds the upper portion 8 through the capillary channels of the fibrous structure of the wick 6.

Due to the fact that the entire supply of combustible material in the liquid phase is inside the capillary structure of the container 4, there is no liquid in the cavity of the channel 2 that could pour out of the housing 1 when the spatial position of the light source changes, for example, when the candle is angularly displaced or moved during the church service. A filled container 4 with a capillary fibrous structure that holds liquid is located in the closed volume of channel 2. Under these conditions, liquid fuel will not spill even if the candle turns over and falls to the floor. The indicated properties of a non-electric portable light source make it possible to use it as a ritual candle that looks like a traditional wax candle.

When burning such a light source in an air atmosphere, products of incomplete combustion are practically not formed. This effect is due to the fact that monohydric alcohols and carbonyl compounds ignite and burn in atmospheric oxygen, forming terminal oxidation products - carbon dioxide (carbon dioxide) and water. The most intense combustion reaction of these organic compounds occurs in an atmosphere of pure oxygen. During the combustion of selected organic compounds, oxygen does not produce smoke and soot (soot), while the products of complete combustion, as a rule, are odorless. In this case, the possibility of soot formation on the surface of surrounding objects, interior elements and the surfaces of the walls of the premises is eliminated; eliminates the possibility of air pollution hazardous to human health products of incomplete combustion of a combustible substance.

These results are achieved due to the new design of the candle and the use of organic compounds as a combustible substance that do not form soot (soot) and smoke during combustion, which, in particular, include ethyl alcohol and acetone. In this case, the material of the fibers of the container is associated with the wetting condition used by the liquid working substance.

After the end of the supply of liquid combustible substance, the used container is replaced with a refilled container. To do this, turn the housing 1 over, remove the removable cover 5, remove the expended container 4 with the wick 6 from the channel 2 and replace it with a new filled container with the wick. After installing the container 4, the cover 5 is inserted into the upper open part of the channel 2, passing the short upper section 8 of the wick through the axial hole made in the cover 5. Before using the newly filled candle, a removable protective cap 9 is installed on the upper end part of the housing 1, which separates the open part channel 2 with a cover 5 from the surrounding air to prevent evaporation of liquid combustible substances through the open part of the wick 6.

It is also possible to replenish the supply of liquid combustible material without replacing the container 4 with the wick 6. For this, the following steps are performed.

The upper section 8 of the wick during operation of the device partially burns. To restore the open part of the wick, its upper section 8 is pulled upwards by about 10 mm due to the longer lower section 7 located between the end part of the plug 3 and the opposite surface of the end part of the container 4. After that, the container 4 is refilled with liquid combustible material, having previously been turned over housing 1 and removing the plug 3. Refueling the container 4 can be done using a syringe filled with the required amount of liquid. To prevent overflow of liquid when filling the container 4 through the wick 6 into the surrounding space, its upper section 8 is pre-squeezed. After filling the container 4 with liquid combustible substance, insert (screw) the plug 3 into the open part of the channel 2, turn the housing 1 into its original working position and install a removable protective cap 9.

The operation of the device made according to other variants of the invention is carried out in a similar way.

The process of operation of a light source made in the form of a lamp, which differs from a candle only in the shape of the case, coincides with the process of operation of a light source made in the form of a candle. When using lavender extract, which has antiseptic and antispasmodic properties, as an additional aromatic component of a combustible substance in the surrounding airspace, a pleasant and soothing smell of lavender is formed. The use of sodium bicarbonate as an additional coloring component of a combustible substance ensures a yellow color of the flame during the burning of ethyl alcohol.

The above-described embodiments of the invention are based on specific device designs and the use of ethyl alcohol as a liquid combustible substance, but this does not exclude the possibility of achieving technical results in other particular cases of the invention as described in the independent claim. Depending on the specific technical requirements for the candle, other options are possible for the design of the candle, the use of other materials of the fibrous structure of the container and monohydric alcohols as a liquid combustible material in accordance with the essential conditions of the invention. In particular, lavsan or other man-made fibers can be used instead of nylon as the material of the fibers of the container. Along with ethyl alcohol and methyl alcohol or a mixture of monohydric alcohols, it can be used as a monohydric alcohol, a wetting fiber of a container. The combustible substance may include carbonyl compounds, including aldehydes and ketones, in particular acetone related to saturated ketones, a mixture of carbonyl compounds or a mixture of alcohols with carbonyl compounds, for example, acetonyl alcohol, as a main component.

It is also possible one-piece execution of the device body (without using a removable end cap). Depending on the specific conditions and requirements, the body of the light source can have a different shape - axisymmetric or asymmetric.

In various embodiments, the device made according to the invention can be used as a portable or stationary (non-portable) non-electric light source with continuous supply of the wick with a combustible liquid. During operation of the light source, products of incomplete combustion are not formed, which can lead to soot formation on the surface of surrounding objects, interior elements of temples and the surfaces of the walls of the premises. It also excludes the possibility of contamination of the surrounding air with fine particles and gaseous components hazardous to human health, which are formed when traditionally used wax and paraffin candles and lamp oil are burned.
