Description

Technical Field

[0001] The utility model relates to the technical field of biomass energy, in particular to a biomass charcoal storage bin. Background Art

[0002] Biochar is a carbon-rich product formed by carbonizing plants, plant waste, municipal waste, and urban waste. Biochar can be used in agricultural soil improvement, effectively improving soil water holding capacity and nutrient availability, while also increasing microbial activity.

[0003] Biochar is similar to coal in that it contains high carbon and hydrogen contents. When it is piled in the air, it will slowly oxidize and release heat, so it needs to be stored in a dark and cool environment.

[0004] During the biochar stacking process, the biochar at the center of the stack will slowly oxidize and generate heat. Since biochar is mainly in powder form, its thermal conductivity is poor. The heat generated in the center of the stack is difficult to dissipate, which will cause the temperature in the center of the biochar pile to rise. The temperature rise will further accelerate the oxidation of the biochar, and eventually lead to spontaneous combustion.

[0005] Existing storage bins typically use air conditioning to regulate the temperature inside, keeping the bins relatively cool. However, biochar itself has poor thermal conductivity, and its powdery form makes it difficult for the center of the biochar pile to circulate with the air inside the bin. Therefore, using air conditioning to directly cool the bins is still not effective in reducing the risk of spontaneous combustion during biochar storage. Utility Model Content

[0006] In view of the problem that the air conditioner is used to adjust the temperature of the storage bin in the prior art, the heat generated at the center of the biochar pile is difficult to dissipate due to the performance characteristics of the biochar itself, and the air conditioning adjustment effect is poor, the utility model proposes a biochar storage bin.

[0007] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0008] A biochar storage bin comprises a bin body, an air conditioner and a loading platform are arranged in the bin body, a heat dissipation pipe perpendicular to the ground is installed at the center of the loading platform, and the height of the heat dissipation pipe is higher than that of the biochar pile.

[0009] The air conditioner regulates and controls the temperature inside the storage bin, keeping it relatively cool. The heat pipes cool the bin by continuously exchanging heat with the air inside. The biomass charcoal pile is then placed on a loading platform, where the heat pipes facilitate heat exchange between the core of the biomass pile and the outside environment, thereby cooling the core of the biomass charcoal pile.

[0010] Preferably, a cold water circulation machine is further provided in the warehouse body, and the water inlet pipe and the recovery pipe of the cold water circulation machine are respectively connected to the heat dissipation pipe.

[0011] When the heat dissipation pipe cannot meet the cooling requirements at the center of the biomass charcoal pile simply by exchanging heat with the air, the staff can start the cold water circulation machine to allow cold water to continuously enter the heat dissipation pipe, thereby ensuring that the heat dissipation pipe is in a relatively low temperature state.

[0012] Preferably, the heat dissipation pipe includes an outer sleeve, an inner sleeve is fixed on the bottom wall of the outer sleeve, one end of the water inlet pipe passes through the top wall of the outer sleeve and is connected with the inner cavity of the inner sleeve, a first through hole for connecting to the inner cavity of the outer sleeve is opened at the bottom of the side wall of the inner sleeve, and the recovery pipe passes through the side wall of the outer sleeve and is connected with the inner cavity of the outer sleeve.

[0013] The heat dissipation pipe is arranged in the form of a double-layer sleeve, and cold water enters the inner cavity of the inner sleeve from the bottom wall of the outer sleeve, flows into the outer sleeve through the first through hole at the bottom of the inner sleeve side wall, and then flows out of the outer sleeve from bottom to top; the above arrangement enables the water inlet pipe and the recovery pipe to be located above the biomass charcoal pile, which is convenient for the staff to replace the water inlet pipe or the recovery pipe in time when it is damaged. The arrangement of the inner and outer sleeves indirectly realizes the cold water entering from the bottom and exiting from the top in the outer sleeve, so that when the cold water flow rate of the water inlet pipe is low, the outer sleeve is still full of cold water.

[0014] Preferably, the upper end of the outer sleeve is open, a top cover is provided at the opening, an inner wall of the top cover is provided with an internal thread, an outer wall of the outer sleeve is provided with an external thread matching the internal thread, and a second through hole for the water inlet pipe to pass through is provided on the top cover.

[0015] When the outer sleeve and the inner sleeve need to be cleaned after being used for a long time, the staff can easily unscrew the top cover and clean the inside.

[0016] Preferably, a first water diversion pipe is provided on the inner sleeve, a second water diversion pipe is provided on the outer sleeve, the water inlet pipe and the recovery pipe are configured as plastic hoses, the water inlet pipe is sleeved on the first water diversion pipe, and the recovery pipe is sleeved on the second water diversion pipe.

[0017] By arranging the water inlet pipe and the recovery pipe as plastic hoses and arranging the first water diversion pipe and the second water diversion pipe on the inner sleeve, it is more convenient to disassemble the water inlet pipe and the recovery pipe.

[0018] Preferably, the bottom wall of the outer sleeve extends outward to form an extension portion, and the extension portion is fixed to the loading platform by bolts.

[0019] The purpose of fixing the outer sleeve on the stage is better achieved by the bolts of the extension part, making it convenient for workers to disassemble and replace the heat dissipation pipe.

[0020] Preferably, the inner sleeve is made of thermal insulation material, and a temperature measuring device for detecting the temperature of the recovery pipe is also provided in the bin body.

[0021] By setting the inner sleeve to be an insulating material, the cold water in the inner sleeve will not directly affect the temperature of the cold water in the outer sleeve, so that the temperature of the water flowing out of the outer sleeve recovery pipe can more accurately reflect the temperature at the center of the biomass charcoal pile, so that the staff can adjust the water inlet speed of the cold water circulation machine to the heat dissipation pipe in time according to the temperature change of the recovery pipe.

DETAILED DESCRIPTION

[0027] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0028] Example

[0029] like Figure 1-3 As shown, a biochar storage bin includes a bin body 110 equipped with air conditioning to keep the interior of the bin relatively cool. Multiple platforms 120 for stacking biochar are provided within the bin body 110. A heat pipe 130, perpendicular to the ground, is installed at the center of each platform 120. When stacking biochar, the height of the biochar pile should be lower than that of the heat pipe 130, allowing the heat pipe 130 to directly exchange heat with the outside air, thereby cooling the center of the biochar pile.

[0030] When the center of the biomass charcoal pile continues to heat up and the heat exchange between the heat pipe 130 and the air alone cannot meet the cooling requirements of the biomass charcoal pile, the cold water circulation machine 140 is started, and water is supplied to the heat pipe 130 through the water inlet pipe 1401, and the hot water in the heat pipe 130 is recovered to the cold water circulation machine 140 through the recovery pipe 1402, thereby achieving the purpose of cooling the heat pipe 130.

[0031] The heat dissipation pipe 130 of this embodiment includes an outer sleeve 1301, and the bottom wall of the outer sleeve 1301 extends outward to form an extension portion 1308, and the extension portion 1308 is fixed to the workbench 120 by bolts 1309; an inner sleeve 1302 is fixed to the bottom wall of the outer sleeve 1301, one end of the water inlet pipe 1401 passes through the top wall of the outer sleeve 1301 and is connected to the inner cavity of the inner sleeve 1302, and a first through hole 1303 for connecting to the inner cavity of the outer sleeve 1301 is provided at the bottom of the side wall of the inner sleeve 1302, and the recovery pipe 1402 passes through the side wall of the outer sleeve 1301 and is connected to the inner cavity of the outer sleeve 1301. By setting the heat dissipation pipe 130 as a double-layer sleeve, cold water enters the inner cavity of the inner sleeve 1302 from the bottom wall of the outer sleeve 1301, flows into the outer sleeve 1301 through the first through hole 1303 at the bottom of the side wall of the inner sleeve 1302, and then flows out of the outer sleeve 1301 from bottom to top; the above setting makes the water inlet pipe 1401 and the recovery pipe 1402 both located above the biomass charcoal pile, which is convenient for the staff to replace the water inlet pipe 1401 or the recovery pipe 1402 in time when it is damaged. Among them, through the setting of the inner and outer sleeves 1301, the cold water is indirectly realized from the bottom in and out of the outer sleeve 1301, so that when the cold water flow rate of the water inlet pipe 1401 is low, the outer sleeve 1301 is still full of cold water.

[0032] When the outer sleeve 1301 and the inner sleeve 1302 need to be cleaned after prolonged use, the outer sleeve 1301 is configured as a cylindrical shape with an open top end. The opening is provided with a top cover 1304. The inner wall of the top cover 1304 is provided with an internal thread, and the outer wall of the outer sleeve 1301 is provided with an external thread that matches the internal thread. This allows workers to easily unscrew the top cover 1304 and clean the interior. The top cover 1304 is provided with a second through hole 1305 for the water inlet pipe 1401 to pass through.

[0033] In order to facilitate the disassembly of the water inlet pipe 1401, a first water diversion pipe 1306 is provided on the inner sleeve 1302, and a second water diversion pipe 1307 is provided on the outer sleeve 1301. The water inlet pipe 1401 and the recovery pipe 1402 are configured as plastic hoses. The water inlet pipe 1401 is sleeved on the first water diversion pipe 1306, and the recovery pipe 1402 is sleeved on the second water diversion pipe 1307.

[0034] In order to more accurately measure the water temperature of the water discharged from the heat dissipation pipe 130, the inner sleeve 1302 is made of insulating material so that the cold water in the inner sleeve 1302 will not directly affect the temperature of the cold water in the outer sleeve 1301, so that the temperature flowing out of the recovery pipe 1402 of the outer sleeve 1301 can more accurately reflect the temperature at the center of the biomass charcoal pile. The staff can detect the temperature changes of the water pipe according to the temperature detection device 1501 and adjust the water inlet speed of the cold water circulation machine 140 to the heat dissipation pipe 130 in time.

[0035] In short, the above is only a preferred embodiment of this embodiment, and all equivalent changes and modifications made according to the scope of the patent application of this embodiment should fall within the scope of coverage of the patent of this embodiment.
