Description

Technical Field

[0001] The utility model relates to the technical field of hot blast stoves, in particular to a high-efficiency heat dissipation particle combustion stove. Background Art

[0002] The pellet combustion furnace uses agricultural and forestry waste particles such as straw as fuel and adopts a semi-gasification combustion method, which effectively avoids the slagging problem of straw particles during direct combustion. By controlling air distribution, feeding, gasification and combustion, efficient and clean combustion is achieved in the furnace. The pellet combustion furnace in the prior art does not have a heat exchange medium. During the combustion process, the combustion of particles causes the temperature in the furnace to be high. Generally, a fan is used for heat dissipation, but the heat dissipation effect of the fan is limited and it cannot cool the furnace body in time, causing the electrical components of the furnace body to be in a high temperature working environment. They are prone to aging after long-term operation, which greatly shortens the service life of the equipment. The name of the Chinese utility model patent is: A biomass pellet stove. The patent with announcement number CN216048336U discloses that the pellet stove box is provided with a storage bin and a combustion component and a heat exchange component connected to the storage bin in sequence. The combustion component includes a detachably connected feeding device and a burner. The heat exchange component includes a water tank with a water inlet and a water outlet and a smoke exhaust pipe running through the water tank. The smoke exhaust pipe is distributed in an S shape, including a plurality of smoke exhaust pipes arranged up and down. Each smoke exhaust pipe is equipped with a cleaning rod. Although the problem of dust and impurities adsorbed on the wall of the smoke exhaust pipe is solved to a certain extent, there are still problems of low heat exchange efficiency and unsatisfactory heat dissipation effect, because the high temperature heat generated in the combustion chamber cannot be dissipated and discharged in time, resulting in a high working environment temperature of the entire furnace body, which affects the normal use and life of various components.

[0045] In order to solve the limitations of the prior art, this embodiment provides a technical solution, and the technical solution of the utility model is further described below in conjunction with the drawings and embodiments.

[0046] The utility model is mainly aimed at improving the existing problems of low heat exchange efficiency and excessively high internal temperature of the equipment during operation, which lead to a bad internal working environment and affect the service life of internal electrical components. Unlike conventional particle combustion stoves in the prior art, the particle combustion stove in the present application timely and effectively replaces and discharges the heat generated by the combustion chamber 209 by setting a heat dissipation component and a heat exchange component to cooperate with each other, thereby preventing the temperature in the combustion chamber 209 and the flue from being too high, causing the overall temperature in the box 100 to be too high, thereby avoiding the influence of the high temperature working environment on the service life of electrical components. The specific structure is as follows:

[0047] See attached Figure 1-4A high-efficiency heat dissipation particle combustion furnace includes a box body 100, a furnace body 200, a silo 500 and an electronic control system. The electronic control system is mainly used to control the actions of various electrical components. The box body 100 is surrounded by decorative panels, and the furnace body 200 and the silo 500 are located inside the box body 100. The silo 500 is used to store particle materials, and particles are transported to a combustion chamber 209 in the furnace body 200 through a feeding assembly 400. The combustion chamber 209 is provided with a channel for the reciprocating movement of an ignition rod of an ignition assembly 600. The ignition rod reciprocates to enter the combustion chamber 209 for ignition, and exits the combustion chamber 209 after the ignition is completed. Here, by setting the ignition rod to reciprocate, it is beneficial to avoid the ignition rod being in a high-temperature environment of the burner all the time, thereby protecting the structure of the ignition rod, effectively extending the service life of the ignition rod, and reducing the maintenance cost of the equipment. The discharge port of the silo 500 is connected to the feed assembly 400, and the feed assembly 400 is connected to the burner in the combustion chamber 209 through a dragon structure. A feed port 103 is also provided on the top of the box body 100, and the feed port 103 is connected to the silo 500. In addition, a blower is also provided under the feed assembly 400, and the blower is used to input air into the combustion chamber 209 to provide oxygen required for combustion. The particle combustion furnace also includes: a heat exchange component, in which a heat exchange channel is arranged, and a heat exchange medium circulates in the heat exchange channel. The heat exchange medium here can be water or other fluids. The heat exchange medium exchanges heat with the flue gas duct. The flue gas duct is located between the combustion chamber 209 and the air outlet 101 of the furnace body 200. It can be understood that: the heat exchange medium is used to absorb the heat generated by the combustion of fuel in the combustion chamber 209 through the heat exchange of the flue gas duct, so as to effectively reduce the exhaust temperature at the air outlet 101, so as to achieve the effect of energy saving and emission reduction; a heat dissipation component, which is used to displace the heat displaced by the heat exchange component and discharge it into the air to provide hot air. It can be understood that: the heat dissipation component mainly exchanges the heat absorbed by the flue gas duct from the furnace body through the fan 305 and the surface cooler 300 and then discharges the hot air. For details, see the attached Figure 5-9 The heat exchange channel includes a heat exchange cavity 212 and a waterway header 208. The heat exchange cavity 212 is a closed space sealed by the enclosure 201. The waterway header 208 is located at the bottom of the heat exchange cavity 212 and communicates with it. The heat exchange cavity 212 is communicated with the waterway header 208 and a heat exchange medium circulates inside. The heat exchange cavity 212 and the waterway header 208 are both in contact with the flue gas pipeline for heat exchange. The waterway header 208 is respectively communicated with the water inlet pipe 102 and the main return pipe 303. For details, see the attached Figure 10-12The flue gas duct includes a combustion chamber 209, a first smoke pipe 204, an upper header 203, a second smoke pipe 211, a lower header 210 and a flue header 207. The combustion chamber 209 is completely located inside the heat exchange cavity 212 and is surrounded by the enclosure 201. The first smoke pipe 204 is provided with a plurality of parallel smoke pipes and the two ends of the smoke pipe are respectively connected to the combustion chamber 209 and the upper header 203. Specifically, the first smoke pipe 204 is arranged in three rows, with 5 pipes in each row. The bottom end of the first smoke pipe 204 is connected to the combustion chamber 209, and the top end is connected to the upper header 203. An openable and closable upper cover is also provided on the top of the box body 100. The upper cover is located directly above the upper header 203, mainly to facilitate timely cleaning of the soot in the upper header 203, the first smoke pipe 204 and the second smoke pipe 211, which is convenient and quick. The second smoke pipe 211 is provided with a plurality of parallel smoke pipes and the two ends of the smoke pipe are respectively connected to the upper header 203 and the lower header 210. Specifically, the second smoke pipe 211 is arranged in a row with 5 pipes in each row. The top end of the second smoke pipe 211 is connected to the upper header 203, and the bottom end is connected to the lower header 210. The gap between the bottom of the combustion chamber 209 and the lower header 210 is in the heat exchange cavity 212. The meaning here can be understood as that except for the furnace door 202, the other walls of the combustion chamber 209 are in the heat exchange cavity 212 and are in contact with the heat exchange medium for heat exchange. The lower header 210 is connected to the hot air outlet of the smoke exhaust fan 206 through the flue header 207. The purpose of setting the flue header 207 here is to reduce wind resistance and thereby reduce the noise of equipment operation. The meaning of the hot air outlet here is mainly that the smoke passes through the flue header 207 and is discharged through the hot air outlet of the smoke exhaust fan 206. The combustion chamber 209 , the first smoke pipe 204 and the second smoke pipe 211 are all located in the heat exchange cavity 212 and are in contact with the heat exchange medium in the heat exchange cavity 212 for heat exchange. The lower header 210 is in contact with the waterway header 208 for heat exchange. The combustion chamber 209 is connected to the outside atmosphere through the furnace door 202, and the lower connecting box 210 is also provided with a cleaning door 213. The cleaning door 213 and the furnace door 202 are both installed on the box body 100. By setting the specific structure of the flue gas duct, the heat in the combustion chamber 209 is exported through the first smoke pipe 204 and the second smoke pipe 211. At the same time, the heat in the smoke pipe is collected and transferred with the help of the upper connecting box 203, the lower connecting box 210 and the flue manifold box 207. In addition, by setting the heat exchange cavity 212 to fully contact and exchange heat with the combustion chamber 209, the first smoke pipe 204 and the second smoke pipe 211, and the lower connecting box 210 and the water channel manifold 208, the temperature at the air outlet 101 of the smoke exhaust fan 206 is effectively reduced, the heat exchange efficiency is improved, and the purpose of effectively reducing the working environment in the furnace body is achieved.

[0048] See attached Figure 2-4The heat dissipation component includes a surface cooler 300 and a fan 305, the surface cooler 300 includes a medium channel and an air channel, wherein the medium channel is used to circulate a heat exchange medium, and the heat exchange medium is connected to the heat exchange medium in the heat exchange cavity 212. The surface cooler 300 is installed on one side of the furnace body 200. Preferably, the surface cooler 300 is installed on the outer wall of the heat exchange cavity 212 and is located between the heat exchange cavity 212 and the silo 500. The installation position of the surface cooler 300 here is also conducive to further dissipating the heat in the heat exchange cavity 212. The medium channel of the surface cooler 300 is installed in parallel in the heat exchange channel of the heat exchange component. Specifically, the upper header 203 is connected to the medium channel entrance of the surface cooler 300 through the upper water pipe 301. The upper channel 205 can also be connected in series between the upper header 203 and the upper water pipe 301. The purpose of setting the upper channel 205 is to be used for buffering and transfer to prevent the water pressure from suddenly increasing due to the sudden reduction of the cross-sectional area of ​​the upper water pipe 301, which affects the service life of the equipment. In addition, other pipeline interfaces can be opened on the upper channel 205 to achieve multi-purpose applications. For example, an outlet pipe 214 is opened. Multiple groups of heating equipment can be connected in parallel or in series between the outlet pipe 214 and the main return pipe 303 for heating multiple spaces. The outlet of the medium channel of the surface cooler 300 is connected to the main return pipe 303 through the return pipe 302. The circulation pump 304 is installed in series on the return pipe 302. The inlet pipe 102 and the main return pipe 303 can be externally connected to the heating equipment for heating. The exhaust port of the fan 305 is connected to the air channel inlet of the cooler 300, and the outlet of the air channel is connected to the atmosphere outside the box 100. The hot air discharged from the outlet of the air channel is used for heating. In addition, a hollow air inlet is provided on the side wall of the box 100, and the position of the air inlet is located on the side wall of the box 100 near the fan 305. Specifically, the outlet of the air channel of the cooler 300 is connected to the air guide 306, which is installed on the side wall of the box 100 and is provided with a plurality of parallel air guide plates. The setting of the air guide 306 here is conducive to guiding the air flow, thereby accelerating the discharge of hot air.

[0049] When using the pellet combustion furnace of the present application for heating, the pellet material is added to the silo 500 for storage through the feeding port 103 at the top of the box body 100, the feeding component 400 works to transport the pellets to the combustion chamber 209, the ignition component 600 works to extend the end of the ignition rod into the combustion chamber 209 to ignite the material and then exit, and the high-temperature flue gas generated by the combustion of the pellets enters the first smoke pipe 204 through the combustion chamber 209, enters the second smoke pipe 211 through the upper header 203, enters the lower header 210 through the second smoke pipe 211, and then passes through the lower header 210 through the flue header 207 and is discharged from the air outlet 101 of the smoke exhaust fan 206. In the above process, the heat exchange medium flows in from the upper water pipe 301 and flows out from the main return water pipe 303. The outlet pipe 214 of the heat exchange medium and the main return water pipe 303 can be connected to an external heating device for heating, and the combustion There is contact heat exchange between the chamber 209 and the heat exchange cavity 212, the first smoke pipe 204 and the heat exchange cavity 212, the second smoke pipe 211 and the heat exchange cavity 212, the lower header 210 and the heat exchange cavity 212, and the lower header 210 and the water channel header 208. Heat exchange medium flows in the heat exchange cavity 212 and the water channel header 208. The heat exchange medium in the heat exchange cavity 212 also flows through the upper channel 205 and the upper water pipe 301 through the medium channel of the surface cooler 300 and then flows back to the main return water pipe 303 through the return pipe 302. At the same time, the exhaust port of the fan 305 is connected to the air channel of the surface cooler 300, and the air is blown into the air channel of the surface cooler 300, and the high-temperature air is blown out through the air guide part 306. The whole process not only reduces the temperature of the working environment of the whole equipment, but also reduces the exhaust temperature of the air outlet 101, thereby further improving the thermal efficiency. The heat exchange method for a high-efficiency heat dissipation particle combustion furnace in the present application includes two paths. Path one is to form a hot fluid discharge after contact heat exchange with the heat exchange medium in the heat exchange cavity 212, and path two is to form hot air discharge after contact heat exchange with the heat exchange medium in the heat exchange cavity 212 through the joint action of the surface cooler 300 and the fan 305. Different from the conventional particle combustion furnace, the present device is provided with two heat exchange methods, which not only reduces the working environment temperature of the combustion furnace, but also improves the hot air efficiency of the combustion furnace, and the heat exchange medium can also provide heating for the external heating equipment.
