Wood pellet stove for concrete curing capable of carbon neutral at construction sites in the winter, realizing carbon neutrality

This invention relates to a wood pellet stove for curing concrete at construction sites in the winter, realizing carbon neutrality. More specifically, by using wood pellets, which are designated as an alternative to fossil fuels as a representative forest biomass renewable energy for carbon neutrality, Not only is it clean, there is no risk of depletion, it can be recycled without pollution, and it suppresses the generation of various toxic gases during the combustion process, allowing it to be used in large quantities over a long period of time without harming the environment and the human body. In particular, wood pellets By securing a relatively long heating time of 10 hours in which the wood burns and generates heat, and then heat is generated by carbonized charcoal, rather than burning quickly at high temperature, longer and continuous combustion with an appropriate and uniform amount of heat is achieved. By providing sufficient heat for winter concrete curing at outdoor construction sites for a long time without additional fuel supplementation, it ensures the quality of concrete curing, dramatically reduces the cost of stove maintenance, and eliminates the need for forced heating, which is a disadvantage of existing wood stoves. Regarding wood pellet stoves to solve the following issues: the essential need for an exhaust device, the relatively high cost of purchasing a stove, the difficulty in moving and installing it as a heavy object, and the short combustion time due to the small size of the fuel tank. will be.

Concrete does not undergo curing because chemical reactions do not occur below 5℃, so after pouring concrete in winter, install a stove in the center of the structure to maintain a constant indoor temperature to prevent moisture inside the concrete from freezing. In addition, we ensure that a smooth chemical reaction occurs inside the concrete.

At this time, the amount of heat loss due to curing of concrete must be calculated mathematically and scientifically to compensate for the amount of heat lost, so it is necessary to supply heat evenly. Therefore, it is not advisable to simply use a stove that generates a lot of heat. You must calculate the exact amount of heat loss and light a stove that minimizes the amount of heat loss to achieve the maximum effect at the minimum cost.

For example, when curing concrete in the winter, it is recommended to keep the surrounding temperature constant at approximately 5℃ or higher. At temperatures lower than this, the curing chemical reaction of concrete does not occur, and if the temperature is too high, the surface after curing is damaged due to rapid moisture drying. It causes defects such as cracks or roughening of the surface.

Therefore, in the field, there is a need for a stove that can maintain heat generation at a uniform temperature for a long period of time, rather than a stove that provides high thermal energy.

Meanwhile, most stoves used for curing concrete in the winter are manufactured and used directly on site. Steel containers such as drums located around the site are processed to form a stove, and fuel is injected into the stove for combustion, thereby maintaining a constant ambient temperature. It is impossible to prevent the temperature from falling below this level.

At this time, various fuels are used. For example, stoves using kerosene, methanol, charcoal, coconut charcoal, bamboo charcoal, etc. are being used.

However, when burning this fuel, it was inconvenient to replenish it approximately every 4 to 5 hours, so it was inevitable to deploy additional manpower to replenish fuel in the stove for continuous concrete curing at night when workers withdrew. This caused an increase in labor costs.

In this way, the reason for periodically replenishing fuel is that although burning a large amount of fuel at once increases the combustion time, concrete curing becomes a problem due to the high heat generated when a large amount of fuel is burned at the same time. Because it can happen. In addition, when a large amount of fuel is burned at once, incomplete combustion occurs due to insufficient oxygen, and the ignition temperature drops rapidly, preventing continuous combustion or the fire goes out.

Therefore, in the case of stoves that use fuel, there is an active demand for technology development of stoves with a long combustion time to enable continuous curing of concrete without the need to periodically replenish an appropriate amount of solid fuel.

In addition, the United Nations Framework Convention on Climate Change (UNFCCC) and the United Nations Intergovernmental Panel on Climate Change (IPCC) recommend the use of forest biomass as an alternative energy source to prevent air pollution, such as kerosene, methanol, charcoal, palm charcoal, and bamboo charcoal. .

Typically, wood pellets are an eco-friendly forest biomass material manufactured using parts that cannot be used as logs during the processing process or trees that cannot be processed into logs due to unforeseen reasons such as various natural disasters such as floods, landslides, earthquakes, etc. , Normally, the carbon generated in the process of growing and cutting down trees by absorbing carbon from the atmosphere is calculated as greenhouse gas statistics, so these wood pellets are also recognized as carbon-neutral fuel because they are not considered to emit carbon when burning fuel. I have received it.

Therefore, there is an active demand for the development of technology for stoves mainly using wood pellets.

By suppressing the occurrence of heat, it can be used in large quantities over a long period of time without causing harm to the environment and the human body. In particular, the wood of the wood pellets burns and generates heat for 10 hours, and then the heat is generated by carbonized charcoal. By securing a relatively long heating time to ensure longer and more continuous combustion with an appropriate and uniform amount of heat rather than rapid combustion at high temperatures, sufficient heat required for winter concrete curing at outdoor construction sites is provided for a long period of time without additional fuel supplementation, thereby curing concrete. It guarantees quality and allows the cost of stove maintenance to be dramatically reduced. The disadvantages of existing wood stoves are that they must be equipped with a forced exhaust device, the purchase cost of the stove is relatively expensive, and it is easy to install as a heavy product.

The stove according to the present invention serves to provide heating for curing concrete poured outdoors, especially at an outdoor construction site. At this time, wood pellets are preferably used as fuel to slowly burn to produce sufficient heat required for curing concrete. It can be provided continuously over a long period of time.

More specifically, the wood pellet stove for curing concrete at construction sites in the winter, which has achieved carbon neutrality according to the present invention, largely consists of a support part 100, a combustion part 20, and a support cover 30, as shown in Figures 1 to 3. ) and a discharge unit 40.

First, the combustion unit 20 is coupled to the upper part of the support unit 100 and has a cylindrical structure capable of receiving pellets inside, forming a combustion space 21 for the pellets received therein.

The combustion unit 20 may have a cylindrical structure with open upper and lower ends, and a support unit 100 may be connected to the open lower end of the combustion unit 20, and a discharge unit 40 may be connected to the open upper end of the combustion unit 20. there is.

The pellets accommodated in the combustion unit 20 are ignited from the top to enable downward combustion. Starting with the initial stage of ignition, the combustion reaction of the upper pellet within the combustion space 21, according to the ignition chain reaction of the stacked pellets, As the combustion part is gradually moved to the lower part, heat dissipation can be gradually achieved in the entire combustion part 20.

In the combustion unit 20, a plurality of through holes 22 and an intake port may be formed along the circumferential direction. The through holes 22 and the intake port may provide functions such as supplying air for combustion of pellets or releasing combustion heat. Perform.

In particular, the through hole 22 and the intake port are designed to more effectively induce the ignition reaction of the upper pellets accommodated in the combustion space 21 in the initial stage of combustion, and to maintain combustion in the middle and end stages of combustion following ignition. It has a structure that allows the total combustion time to be extended by suppressing the rapid combustion reaction and appropriately delaying the combustion time.

To this end, a plurality of through holes 22 may be formed along the upper circumferential direction of the combustion unit 20 and may be formed at equal intervals.

The through hole (22) serves to quickly supply air to the top of the combustion space (21) during the initial ignition of the pellets, and has a larger penetration area than that of the first intake port (23) in consideration of smooth ignition of the pellets. to be able to have

For example, the penetration area of the through hole 22 is preferably set to a size that allows a unit pellet to sufficiently escape, but the pellets contained in the combustion space 21 are discharged to the outside through the through hole 22. To prevent this, it is preferable to fill the pellets below the height at which the through hole 22 is formed when initially charging the pellets.

When combustion begins after ignition of the pellets, the air flow rate sucked into the through hole 22 decreases due to the high temperature rising air current in the combustion space 21, and the main air supply for continuous combustion is through the first intake port 23. It can be done.

Both the through hole 22 and the first suction port 23 may have a perforated structure in a circular shape, but of course, they can be appropriately modified depending on the type of pellet, purpose of use, site situation, etc.

The first intake port 23 may be formed continuously from a position spaced a certain distance downward from the through hole 22 to the lower portion of the combustion unit 20.

The first inlet 23 starts from a position spaced apart from the bottom of the through-hole 22 by a certain distance, and at this time, the first micro-hole is not formed between the through-hole 22 and the first inlet 23 at the uppermost level. A formation section 1Ez may be provided.

In the first non-formation section 1Ez, since the outer surface of the combustion section 20 is configured to seal the pellets in all directions, a structure is provided in which the amount of air supplied to the pellets is relatively rare.

That is, in the process where the combustion of the pellet gradually progresses downward, when the combustion site enters the first non-formation section (1Ez), the combustion reaction can be relatively delayed in the first non-formation section (1Ez). Since the air supply through the first intake port 23 can be continuously provided, a structure is provided to ensure safe combustion just enough to slowly delay the combustion speed in order to prevent incomplete combustion or complete extinguishment of the pellets. You will lose.

The vertical height of the first unformed section 1Ez is preferably formed to be at least larger than the diameter of the through hole 22, assuming that the through hole 22 has a circular shape.

The first intake port 23 may refer to through holes formed continuously from the point where the first unformed section 1Ez ends to the bottom of the combustion section 20.

Depending on the combustion progress stage below the first unformed section (1Ez), the combustion section 20 can be arbitrarily divided into sections of the initial stage of combustion (1Bz), the middle stage of combustion (2Bz), and the end stage of combustion (3Bz), A plurality of first intake ports 23 may be arranged in each stage section.

In particular, as combustion progresses, ash (charcoal), a combustion by-product, is deposited on the upper part of the pellet, and the volume of this ash portion decreases by approximately 50%. As the density relatively increases, breathability decreases and the ash itself The possibility of blocking the first intake port 23 also increases.

In the initial stage of combustion, voids exist between the pellets throughout the entire combustion space 21, so even if the pellets are stacked, breathability is guaranteed and the pellets do not completely block the first intake port 23, so the first intake port 23 is not completely blocked. 1 It has a structure that allows smooth air supply through the intake port (23).

Therefore, at the initial stage of combustion (1Bz), the amount of air supplied is relatively reduced to appropriately suppress rapid combustion of pellets.

On the other hand, as combustion progresses, in the middle and end stages of combustion, ash, which is a by-product of combustion of the pellets, is densely deposited on the top of the pellets and blocks the first intake port 23, resulting in incomplete combustion or extinguishment beyond combustion delay. can cause.

In other words, due to the nature of pellet combustion, where the amount of air supply inevitably decreases as combustion progresses, the combustion embers gradually become weaker as they move toward the lower part of the combustion section 20, so the combustion embers gradually weaken from the middle stage of combustion (2Bz) to the end stage of combustion (3Bz). It is a configuration to increase the amount of air supply as it goes further, and allows air to be supplied from the bottom of the wood pellets through the support part 100, which will be described later, to prevent incomplete combustion and digestion of the pellets.

In the case of carbonized ash (charcoal), combustion can continue even if there is a small amount of air inflow, so even if the air supply is not smooth from the side of the combustion unit 20, it can continue to burn and generate heat during the combustion process.

Meanwhile, second and third unformed sections 2Ez and 3Ez in which the first suction port 23 is not perforated may be provided between each stage section to perform the same function as the above-mentioned first unformed section 1Ez. there is.

At this time, the second unformed section (2Ez) is provided between the initial stage of combustion (1Bz) and the middle stage of combustion (2Bz), and the third unformed section (3Ez) is provided between the middle stage of combustion (2Bz) and the end stage of combustion (3Bz). ) can be arranged between.

In other words, if the combustion part of the pellet is located at the initial stage of combustion (1Bz), the middle stage of combustion (2Bz), or the end stage of combustion (3Bz), combustion occurs smoothly, while the combustion part is located between each stage. When entering the second and third unformed sections (2Ez, 3Ez) provided in , combustion delay occurs at that location.

In other words, by alternately inducing and delaying combustion in the downward combustion process of the pellets, the combustion time of the pellets can be increased more effectively in the line of preventing incomplete combustion or complete digestion of the pellets.

On the other hand, since the embers of the ignited pellets tend to weaken toward the end of combustion (3Bz), as part of preventing ignition in the 2nd and 3rd non-formation sections (2Ez, 3Ez), the third non-formation section (2Ez, 3Ez) 3Ez), the upper and lower heights of the sections should be made smaller.

For example, the vertical height of the second unformed section 2Ez is made smaller than that of the first unformed section 1Ez, and the vertical height of the third unformed section 3Ez is made smaller than that of the second unformed section 2Ez, In the process of combustion, combustion delay is gradually achieved for a short period of time.

Next, the support unit 100 serves to support the combustion unit 20 at a certain height from the ground.

In addition, in addition to supporting the combustion unit 20, the support unit 100 communicates with the combustion space 21 of the combustion unit 20 to allow air to be supplied toward the lower part of the open combustion space 21. Perform.

To this end, the support unit 100 may be largely illustrated as including a housing 110 and a support plate 120.

The housing 110 may have a hollow cylindrical interior, and a plurality of second inlet ports 111 are formed along the circumferential direction to supply air into the housing 110.

An upper support 112 supporting the lower end of the combustion unit 20 and a lower support 113 supported on the ground may be extended to the upper and lower ends of the housing 110, respectively.

Inside the housing 110, a diaphragm 114 may be provided to vertically divide the upper space inside the housing 110. At this time, the upper space of the diaphragm 114 divided by the diaphragm 114 is used as the charging space 116. , The lower space is called the inflow space (117).

A plurality of first communication holes 115 may be perforated in the diaphragm 114 so that the charging space 116 and the inlet space 117 communicate with each other.

Accordingly, air flowing into the housing 110 through the second intake port 111, preferably into the inflow space 117, may pass through the diaphragm 114 and flow into the charging space 116.

Although not shown, a lever for controlling the opening and closing amount of the second inlet 111 is installed around the second inlet 111 to control the amount of air heading into the inlet space 117.

A first support ledge 118 may be provided around the upper end of the upper support 112 to support the support plate 120, and the support plate 120, which will be described later, may be seated on the first support ledge 118.

The support plate 120 is a thin plate-shaped structure and can be seated on the first support jaw 118 in a state that is spaced a certain distance upward from the diaphragm 114 of the housing 110 in parallel.

The support plate 120 is located at the bottom of the open combustion section 20 and supports the pellets filled in the combustion space 21 to prevent the pellets from falling into the charging space 116.

A plurality of second communication holes 121 may be perforated in the support plate 120 to allow air flowing into the support portion 100 to pass underneath the supported pellet.

As combustion progresses, the amount of ash accumulated on the pellet gradually increases, and as a result, the air supply action in the combustion space 21 is prevented due to the problem of ash blocking the first intake port 23 and the problem of lowering ventilation due to the density of the ash. This cannot be done smoothly. At this time, the support part 100 that supports the combustion part 20 sucks air and supplies it directly below the pellets, so that the flame is not easily extinguished at the end of combustion and sufficient fire power can be generated. Let it happen.

In particular, since the pellets supported on the upper part of the support plate 120 do not invade the charging space 116 through the support plate 120, not only the inflow space 117 but also the charging space 116 is maintained as an empty space at all times. A state filled with air is established. Accordingly, a structure is provided in which the air charged in the charging space 116 passes through the support plate 120 and is continuously supplied to the pellets, so that efficient combustion of the pellets can be achieved even if the upper ash accumulates.

Next, the support cover 30 is installed between the combustion section 20 and the discharge section 40 and plays the role of seating and supporting the discharge section 40 on the upper part of the combustion section 20.

The support cover 30 has a circular ring shape that is seated around the top of the combustion unit 20, and a third communication hole 31 may be formed in the center to allow combustion gas, flame, heat, etc. to pass through. A second support protrusion 32 is provided around the third communication hole 31 to seat and support the discharge unit 40.

The discharge part 40 is not fixedly fastened to the support cover 30 through a separate fixing means, but is simply seated on the second support jaw 32, so that the support cover 30 is used for filling or moving the pellets. Make it easy to attach and detach from.

Next, the discharge unit 40 is coupled to the upper part of the combustion unit 20 and discharges combustion gas resulting from combustion of pellets in a designated direction, prevents the spread of flame, and performs a heat dissipation function by combustion heat. plays a role in

To this end, the discharge unit 40 may be largely illustrated as including a communication member 41, a heat sink 42, and a bracket 43.

The communication member 41 has a cylindrical structure with the upper and lower ends open and has a structure in which a plurality of discharge ports 44 are formed through the circumferential direction.

Combustion gases, heat, etc. generated from the combustion unit 20 can be properly discharged through the outlet 44, and when a flame occurs, the communication member 41 itself covers the flame from the outside to prevent the spread of the flame. However, indirect exposure of the flame is implemented through the outlet 44 to create a soft lighting atmosphere at night.

The lower end of the communication member 41 may be seated on the second support jaw 32 of the support cover 30.

The heat sink 42 is disposed at a certain distance from the top of the communication member 41 to partially block the open top of the communication member 41.

At this time, the heat sink 42 does not completely seal the top of the communication member 41, but is spaced apart from the top of the communication member 41 at a certain distance, so that combustion gases, etc. can flow to the top of the communication member 41 without difficulty. Allow it to be discharged.

In particular, the heat sink 42 has a sufficient area so that heat can be more effectively dissipated and diffused in all directions.

For example, assuming that the combustion unit 20 is cylindrical, the heat sink 42 has a disk shape with a diameter larger than the maximum diameter of the combustion unit 20, so that heat can be spread in all directions more effectively. Have a structure.

The heat sink 42 can be supported at a distance from the top of the communication member 41 through a plurality of brackets 43. At this time, at least two of each bracket 43 are arranged at an equal angle to maintain the communication member 41. ) and the heat sink (42). Make sure not to seal the space excessively.

Meanwhile, a handle may be formed on the outside of the combustion unit 20 and the communication member 41.

In summary, this design is a representative forest biomass renewable energy for carbon neutrality. By using wood pellets, which are defined as an alternative to fossil fuels, it is not only clean and free from depletion, but also allows for pollution-free regeneration, and enables various types of energy during the combustion process. By suppressing the generation of toxic gases, it can be used in large quantities over a long period of time without causing harm to the environment and the human body. In particular, the wood pellets burn for 10 hours to generate heat, and then the carbonized charcoal By securing a relatively long heating time during which heat is generated, it ensures longer and more continuous combustion with an appropriate and uniform amount of heat rather than rapid combustion at a high temperature, thereby providing sufficient heat needed for curing concrete in the winter at an outdoor construction site for a long period of time without additional fuel supplementation. It ensures the quality of concrete curing and dramatically reduces the cost of stove maintenance. The disadvantages of existing wood stoves are that they must be equipped with a forced exhaust device, the purchase cost of the stove is relatively high, and It provides the advantageous effect of solving problems such as the difficulty of easy movement and installation as a heavy object, and the short combustion time due to the small size of the fuel tank.
