Description

Sawdust particle multifunctional boiler capable of forcibly discharging waste gas

Technical Field

The present invention relates to a sawdust particle multifunctional boiler capable of forcibly discharging exhaust gas, and more particularly, to a sawdust particle multifunctional boiler capable of forcibly discharging exhaust gas, which is formed in such a manner that exhaust gas generated in a combustion chamber is forcibly discharged to the outside through a smoke discharge pipe during heating of the boiler, and is formed in such a manner that an auxiliary tank surrounds the smoke discharge pipe, thereby preventing a risk of accidents caused by leakage of exhaust gas, and recovering heat from the exhaust gas to improve a heating effect.

Background

Generally, a boiler is a device that operates in a state in which a burner is ignited by a control device such as an electronic ignition method and heats water placed in a water tank to obtain heated water and hot water, and is mainly installed and used by using an oil or gas boiler, and various safety devices are attached to the boiler to realize safety of a user, maintain a proper indoor temperature, and enable hot water to be used, thereby realizing convenience of health and daily life.

However, in the oil or gas fired boiler as described above, since the fuel cost of the oil or gas used as the fuel is very high and various electronic and electric devices must be provided to normally operate, the boiler device can be constructed only with a very complicated structure, and thus a large number of parts are consumed, and there is a problem in that the manufacturing cost is increased to increase the installation cost.

In particular, it is difficult to install and use the oil or gas boiler in rural areas or remote areas due to problems of insufficient supply and demand of fuel and economic problems caused by increased logistics costs, and in the case of fossil fuels used in the oil or gas boiler, exhaust gas generated during combustion or gas naturally evaporated in an oil storage tank or the like acts as a substance polluting the global atmospheric environment, and therefore, there is a demand for providing a corresponding countermeasure.

In order to improve such a problem, in recent years, as a boiler for business use in a household of a general farmer or a small-scale factory, a pellet boiler using various pellet fuels (pellet fuel) including wood or other biomass (biomass) or the like is being developed and used.

As a prior art of such a pellet boiler, domestic registered utility model No. 20-0446195 (registration date: 2009.09.28) is disclosed.

Fig. 1 is a perspective view of the chip pellet hot water boiler according to the conventional art, fig. 2 is a sectional view showing an internal structure and an operation state of the chip pellet hot water boiler, and the chip pellet hot water boiler 1 is a chimney-type hot water boiler that burns fuel such as chip pellets or wood chips, heats internal water by combustion heat generated at this time to generate hot water, and uses the heat for heating, hot water supply, various processing processes, and the like.

The hot water boiler is characterized by comprising the following parts: a firebox 2 in which a fuel such as wood dust particles is put for combustion; a hot water storage chamber 29 in which water stored therein is heated by combustion heat generated in the firebox 2 and hot water is generated; and a supply chamber 35 for supplying a predetermined amount of water corresponding to the amount of hot water discharged from the hot water storage chamber 29 through the hot water discharge pipe 33.

However, when the ignition is not normally performed in the firebox 2 and the combustion is not completely performed, a large amount of exhaust gas is generated, and at this time, the exhaust gas is naturally not discharged to the outside and remains in the hot water boiler. However, since the conventional art does not include a structure for forcibly discharging the exhaust gas, there is a possibility that pollutants contained in the exhaust gas may enter the hot water boiler to deteriorate durability of an internal structure, and if the exhaust gas leaks to the outside of the hot water boiler, serious personal injury may occur.

In addition, the sawdust particle hot water boiler according to the related art has a structure in which the supplementary water supply chamber 35 is protruded to the outside, and thus there is a problem in that the supplementary water stored in the supplementary water supply chamber in winter is frozen and is limited in use. Further, the above-mentioned prior art is limited to heating and hot water supply, and has a problem that the use is limited even in summer when a boiler is not used.

Fig. 7 is a partial sectional perspective view illustrating a forced discharge state of the sawdust particle multi-purpose boiler capable of forcibly discharging exhaust gas according to the present invention.

The multifunctional boiler for wood chips particles capable of forcibly discharging exhaust gas according to the present invention is characterized in that a burner 110, a combustion chamber 120, a hot water cylinder 130, an inner flue pipe 140, a coil pipe 151, an auxiliary tank 160, a flue pipe 170, a forced draft pipe 190, and a blower 191 are provided inside a main body casing 100.

The burner 110 is located in the front of the lower end of the boiler, and has a structure in which energy is generated by burning fuel particles, a fuel supply port 111 for continuously supplying and feeding the fuel particles is provided at the upper part, and an air supply part 112 for supplying oxygen required for burning the fuel particles is provided at the lower part.

A plurality of air injection holes 113 are perforated at an upper end of the air supply part 112 to supply oxygen necessary for the combustion of fuel, and in this case, air can be naturally flowed in, but an additional blowing device is additionally provided to forcibly blow out a large amount of air in order to generate strong heating power.

The combustion chamber 120 is located at a rear side portion of the burner 110, and a flame generated in the burner 110 is jetted and burned in the combustion chamber 120, thereby performing heat exchange with the hot water drum 130.

The lower portion of the hot water cylinder 130 filled with water therein is provided with the combustion chamber 120 so that heat is uniformly dispersed over the entire bottom surface of the hot water cylinder 130 to perform heat exchange, thereby maximizing thermal efficiency.

The hot water tank 130 is configured to heat and supply hot water for heating, and is configured to heat, store and supply hot water for heating circulating along a heating pipe 200 connected through a pipeline and disposed on a floor such as a living room or a bedroom, and is configured to be sealed by an upper plate 131, a lower plate 132 and a surrounding plate 133.

A plurality of inner flue tubes 140 are vertically formed between the upper plate 131 and the lower plate 132 of the hot water cylinder 130 to perform heat exchange, and an upper surface of the upper plate 131 and a lower surface of the lower plate 132 are communicated with each other through the plurality of inner flue tubes 140, so that combustion gas including hot gas combusted in the combustion chamber 120 is discharged through the inner flue tubes to perform heat exchange, thereby heating water in the hot water cylinder 130.

In the present invention, the inner flue tube 140 is provided with a retention member 180 to improve the thermal efficiency of the boiler.

The retention member 180 is disposed above the inner flue pipe 140, adjusts the flow of combustion heat with a hanging table 181 hung on the upper plate 131 to improve the heat efficiency, and is formed with a plurality of protrusions 182 to prevent dust generated during the combustion of fuel from being discharged to the outside.

Then, since the hot air passing through the inner flue pipe 140 is subjected to resistance by the protrusion 182 of the stay member 180, the moving speed of the upper portion of the hot air is reduced, and thus the hot air stays in the inner flue pipe, the heat exchange time is prolonged, and as a result, an effect of improving the heat efficiency is obtained, and since the dust generated during the combustion of the fuel is not discharged to the outside, the pollution of the atmospheric environment is reduced.

The exhaust pipe 170 is formed to penetrate the sub-tank 160, one side of which communicates with the combustion chamber 120 and the other side of which is exposed to the outside, and is formed to discharge the exhaust gas generated in the combustion chamber 120 to the outside.

More specifically, the combustion gas passing through the plurality of inner smoke pipes 140 is collected at the upper portion of the hot water cylinder 130 and is discharged to the outside through the exhaust funnel 170 located at the rear side portion of the boiler. The exhaust pipe 170 is formed as a U-shaped duct for discharging the exhaust gas burned in the combustion chamber 130, and has a cleaning unit 171 at a lower end portion thereof.

Then, the dust and impurities contained in the exhaust gas passing through the exhaust hood 170 drop downward while passing through the U-shaped pipe and are accumulated, and the efficiency of the boiler can be improved by periodically cleaning the exhaust hood by the cleaning part 171 located at the lower end.

On the other hand, in the boiler of the present invention, since the amount of the exhaust gas generated is small after the boiler is started for a certain period of time, i.e., after the operation of the burner 110 is stopped, the exhaust gas generated in the combustion chamber 120 is naturally discharged to the outside through the exhaust pipe 170 along the U-shaped pipe via the inner flue pipe 140.

However, the boiler of the present invention generates a large amount of exhaust gas when combustion is initially started, and generates significantly more exhaust gas when fuel is newly supplied for re-combustion due to incomplete combustion or abnormal combustion, compared to the case where combustion is initially started.

In this case, a part of the generated exhaust gas may be naturally discharged along the U-shaped pipe, but a part of the generated exhaust gas may not move along the U-shaped pipe and may be accumulated in the combustion chamber 140, and in this state, there may be a problem of exhaust gas leakage between the internal structures of the main body case 100.

Next, in the boiler of the present invention, the blower 191 is provided in the main body case 100 through the pipe of the forced draft tube 190 formed such that one side is communicated with the inner flue pipe 140 and the other side is communicated with the exhaust funnel 170, so that the exhaust gas generated in the combustion chamber 120 flows to the exhaust funnel 170 through the forced draft tube 190 for a certain period of time when the boiler is initially started.

At this time, the forced discharging pipe 190 is formed such that one side thereof communicates with the upper portion of the inner flue pipe 140 and the other side thereof communicates with the lower portion of the exhaust pipe 170. Accordingly, the exhaust gas generated in the combustion chamber 120 is discharged after heat exchange with the water inside the hot water cylinder 130, thereby further improving heating efficiency, and dust or impurities contained in the exhaust gas discharged from the forced discharge pipe 190 drop by weight and are accumulated on the cleaning opening 171, thereby preventing air pollution.

On the other hand, as described above, the blower should be operated when combustion is first started in the boiler, that is, when the combustor 110 is operated, but after combustion is performed for a certain period of time, that is, when the combustor 110 is stopped, the blower does not need to forcibly discharge the combustion gas.

Next, in the boiler of the present invention, the power of the burner 110 is interlocked with the power of the blower 191, and the blower 191 is operated at the same time as the boiler is operated, so that the exhaust gas flows to the exhaust pipe 170 through the forced draft pipe 190 in time without being accumulated in the combustion chamber 120, and the blower is also stopped when the burner is stopped, thereby preventing unnecessary power consumption.

On the other hand, the exhaust pipe 170 is formed to penetrate the auxiliary tank 160, so that the exhaust gas passing through the exhaust pipe 170 and the water inside the auxiliary tank 160 exchange heat with each other. That is, since the water contained in the auxiliary tank 160 surrounding the exhaust pipe 170 recovers heat of the exhaust gas forcibly discharged, the water contained in the auxiliary tank 160 is heated, and then the water in the auxiliary tank 160 is supplied to the hot water tank 130, there is an advantage that hot water for heating can be heated and supplied in a short time.

On the other hand, an internal heat exchange member 150 is provided inside the hot water cylinder 130 to exchange heat with the water of the hot water cylinder. According to the present invention, the internal heat exchange member 150 is a separate pipe closed from the hot water cylinder 130 in order to use heated water as hot water in a heat exchange process with water inside the hot water cylinder 130.

A coil 151 constituting the internal heat exchange member 150 is wound in a coil shape around the outer side of the plurality of internal smoke tubes 140 provided in the hot water tank 130, and heat-exchanges between water flowing through the coil and heating hot water in the hot water tank 130, a water supply pipe 152 connected to the coil 151 to supply water such as groundwater or tap water is connected to one end of the coil 151, and a drain pipe 153 to drain water supplied through the water supply pipe 150 is connected to the other end of the coil 151.

According to the present invention, the internal heat exchange member 150 allows water heated by starting the boiler to be used when hot water is used in winter, and cools water in the hot water tank 130 in summer to perform a cooling function. Fig. 8 is a system diagram for starting heating and cooling by using the sawdust particle multi-function boiler capable of forcibly discharging exhaust gas according to the present invention, and shows a state in which a three-way valve 320 capable of switching to a connection with a heating pipe 300 or an air conditioner 310 is provided in an inflow pipe 134 and an outflow pipe 135, which are pipes connected from the hot water drum 130.

In winter, the three-way valve 320 is switched to the heating pipe 300, and water of the hot water tank 130 heated by the boiler is circulated and used as heating hot water for raising the floor temperature, and the coil 151 provided in the hot water tank 130 exchanges heat with the heated water in the hot water tank, so that cold water flowing in through the water supply pipe 152 is heated and then discharged through the water discharge pipe 153 to be used as hot water.

On the other hand, in the case of summer season when the boiler is not used, since the boiler is not started and heat is not generated, in this case, the floor temperature is low relative to the building indoor temperature, and therefore, if the water inside the hot water tank is forcibly circulated to the heating pipe of the floor for a certain time, the temperature of the water finally circulated to the hot water tank through the heating pipe is lower than the indoor temperature.

Then, by switching the three-way valve 320 to the air conditioner 310 so that the water in the hot water cylinder 130 is supplied to the air conditioner 310 such as an air cooler provided indoors through a pipe, the hot air in the room can be cooled by the heat exchange of the air conditioner 310.

In addition, when the groundwater lower than the indoor temperature is supplied and flows through the coil 151 in a case where the water temperature inside the hot water cylinder 130 naturally rises due to the outside air temperature, the water stored inside the hot water cylinder 130 exchanges heat with the groundwater of the coil 151 to lower the water temperature, and the water of the hot water cylinder with the lowered water temperature is supplied to the air conditioner through the inflow pipe 134, the indoor cooling effect is doubled.

That is, the air conditioner 310 is a device having a function of reducing the indoor temperature through a heat exchange process with the ambient air while circulating water having a temperature lower than the ambient temperature, and according to the present invention, the air conditioner can have a function of reducing the indoor temperature by being activated in a state where the three-way valve is switched to the air conditioner in summer having a temperature higher than the outside air temperature, and thus a cooling effect can be obtained by the air conditioner.

On the other hand, in view of the characteristic that a certain amount of water is stored in the hot water tank 130, the auxiliary tank 160 is provided in the present invention so that the amount of water consumed in the circulation process in the heating pipe 200 can be replenished in time.

In the present invention, the auxiliary tank 160 supplies water to the hot water drum 130 through the supplementary water supply pipe 161 connected to the lower portion of the auxiliary tank 160, and the auxiliary tank 160 is located inside the main body case 100, so that there is no fear of freezing due to the outside air temperature in winter, and the boiler can be stably driven.

Fig. 9a is a partial perspective view of a sawdust particle multi-purpose boiler that can forcibly discharge exhaust gas according to another embodiment of the present invention. Fig. 9b is a partial sectional view showing a lower structure of a sawdust particle multi-purpose boiler that can forcibly discharge exhaust gas according to another embodiment of the present invention. Fig. 9c is a view showing the state of use of the opening and closing device of the sawdust particle multi-function boiler which can forcibly discharge the exhaust gas according to another embodiment of the present invention.

The invention utilizes the combustion of the wood dust particles to operate the boiler, so that a large amount of impurities such as dust and dust are inevitably accumulated on the lower surface of the boiler. Of course, the user can open and close the front surface (the surface provided with the burner 110) of the main body casing 100 to clean the boiler without operating the boiler, but the user cannot easily directly clean the boiler when the boiler is continuously operated in winter.

Therefore, in the boiler of the present invention, the lower surface of the main body casing 100 is formed in a hopper shape, the screw 400 extending in the front-rear direction is provided at the center of the lower surface of the main body casing 100, and cleaning is performed by the operation of the screw 400.

That is, the lower surface of the main body case 100 is formed to be inclined from the left and right side surfaces of the main body case 100 toward the lower center portion of the main body case 100, and when impurities existing inside the main body case 100 fall onto the lower surface of the main body case 100, the impurities are collected at the center portion due to the inclination. Then, as the screw 400 is operated, dust accumulated at the rear side of the central portion of the lower surface of the main body case 100 is gradually moved to the front side, and most of foreign substances accumulated at the central portion are easily discharged to the outside.

On the other hand, the duct 410 enclosing the screw 400 is provided with an opening and closing means 411 at the front, and when the screw 400 is operated, the opening and closing means 411 is opened to discharge the foreign materials to the outside, and when the screw 400 is not operated, the opening and closing means 411 is closed to prevent the external dust and the like from flowing into the boiler through the duct 410.

On the other hand, the opening/closing means 411 may be manually opened and closed by a user directly, or may be automatically opened when the screw 400 is operated and automatically closed when the screw 400 is not operated. In this case, the opening/closing device 411 is an opening/closing device that is generally used for opening/closing a pipeline such as a duct, and can be designed and implemented according to the user's request.

Fig. 10 is a view showing an automatic water level adjusting device installed in a supplementary tank for makeup water provided in a boiler according to the present invention, and shows a state in which an automatic water level adjusting device 200 is installed at a terminal portion of a pipe for supplying water to the supplementary tank 160.

Fig. 11 is a diagram showing an operation state of an automatic water level adjusting device installed in a supplementary water tank provided in a boiler according to the present invention, where a is a state of supplying water and b is a state of blocking the supply water.

As shown in fig. 9, the automatic water temperature control device 200 provided in the sub-tank 160 includes an inflow pipe portion 210 connected to an external water pipe, a discharge pipe portion 220 for discharging water, a double pipe jaw portion 230, a main valve 240, a space portion 250, a compression coil spring 251, a partition wall 260, a lever 270, a float 280, and a guide cover 290.

The dual line jaw 230 is comprised of: an outer end jaw pipe 231 connected to the inflow pipe portion 210 to pass water therethrough; and an inner end jaw pipe 232 concentrically formed with the outer end jaw pipe 231 and connected to the discharge pipe part 220.

The main valve 240 is provided at a lower portion of the double pipe jaw 230, and is lifted and lowered by a valve operating water pressure acting at the lower portion, and functions to open and close a pipe between the inflow pipe portion 210 and the discharge pipe portion 220, and includes a fine through hole 241 connected to the inflow pipe portion 210.

The space portion 250 is a space formed between the lower portion of the main valve 240 and the partition wall 260, and a compression coil spring 251 is provided in the space portion 250.

The partition wall 260 supporting the lower end of the compression coil spring 251 and forming the space portion 250 is provided with a discharge hole 261 to discharge water inside the space portion 250.

The lever 270 is provided with an auxiliary valve 272 which cooperates with a hinge 271 from a lower portion of the partition wall 260 and corresponds to the discharge hole 261.

Further, a float 280 is provided at a lower end of the lever 270, a magnet 273 is provided between the lever 270 and the float 280 to be attached to each other by magnetic force and to cooperate with each other, and when the water level is detected by the float 280, the open/close main valve 240 supplies water to the sub-tank 160, thereby maintaining a constant water level.

The guide cover 290 functions to guide the floating ball 280, which rises and falls with the water level of the sub-tank 160, to stably move in a certain interval.

The automatic water level control device 200 is installed in the sub-tank 160, and supplies the water to the sub-tank 160 by adjusting the water level of the sub-tank 160 to a predetermined level, and when the temperature of the water in the sub-tank 160 is lowered while supplying the water from the sub-tank 160 to the hot water drum 130 through the supplementary water supply pipe 161, the automatic water level control device 200 is turned on in time and supplies the water.

As shown in fig. 11a), when the water level of the sub-tank 160 is lowered, the float 280 is also lowered, and at this time, the lever 270 rotates about the hinge 271, the sub-valve 272 closing the discharge hole 261 is opened, and the water filled into the space portion 250 blocked by the partition wall 260 is discharged through the discharge hole 261, so that the pressure of the space portion 250 is lowered.

Then, the main valve 240 blocking the double pipe jaw 230 is lowered and opened by the pressure of the upper side portion being larger, so that the inflow pipe portion 210 and the discharge pipe portion 220 are connected to each other, and water is supplied, and the double pipe jaw 230 is composed of the outer end jaw 231 connected to the inflow pipe portion 210 and the inner end jaw 232 connected to the discharge pipe portion 220 concentrically with the outer end jaw 231.

When the water level of the sub-tank 160 rises through the process of replenishing water, the float 280 rises together, and as shown in fig. 11b), the lever 270 rotates about the hinge 271, and the sub-valve 272 closes the discharge hole 261.

At this time, water gradually flows into the space part 250 and is filled through the fine through holes 241 formed in the main valve 240 to connect the inflow pipe part 210, which is the upper part of the main valve 240, and the space part 250, which is the lower part, and at this time, the water pressure on both sides of the inflow pipe part 210 and the space part 250 becomes equal during the filling of water, and the main valve 240 smoothly moves in the upper direction, and the entire pipeline is blocked.
