[0031] Please refer to Figure 1 with Figure 2, this embodiment provides a storage device for flammable materials in the production of activated carbon, including a storage bin 1, a dust removal component, a spraying component 3, a steam distribution pipe 4, a temperature sensor 5, and a control unit; the top of the storage bin 1 is provided with a feed inlet 11 for allowing flammable materials to enter the storage bin 1, and the flammable materials are flammable materials used in the production of activated carbon; the dust removal component includes a dust removal pump, a dust removal bag, and a dust removal pipe 2, the dust removal pipe 2 is connected to the dust removal bag and the storage bin 1, and the dust removal pump is arranged on the dust removal pipe 2 for pumping the dust in the storage bin 1; the spraying component 3 includes a plurality of nozzles 31, the plurality of nozzles 31 are arranged in the storage bin 1 and are arranged at the top of the storage bin 1; the steam distribution pipe 4 is arranged at the bottom of the storage bin 1, the steam distribution pipe 4 is communicated with the bottom of the storage bin 1, and the steam in the steam distribution pipe 4 can enter the storage bin 1 from bottom to top; the temperature sensor 5 is arranged in the storage bin 1; the control unit is electrically connected to the temperature sensor 5, the dust removal component, the spraying component 3, and the steam distribution pipe 4.

[0032] In this embodiment, activated carbon is a carbon material with a highly porous structure and adsorption capacity, and is commonly used in the treatment of air purification, water, and waste gas; the main component of activated carbon is carbon, so a suitable carbon source needs to be selected. Commonly used carbon sources include wood, coconut shell, coal, graphite, fruit shell, etc. Different carbon sources will affect the pore structure and adsorption performance of activated carbon. Activated carbon usually needs to go through an activation process to obtain a highly porous structure and adsorption capacity. The activator can be a chemical substance or a physical condition. Commonly used activators include phosphoric acid, alkali solutions (such as potassium hydroxide, sodium hydroxide), gases (such as carbon dioxide, steam), etc. Among them, the carbon sources including wood, coconut shell, coal, graphite, and fruit shell are all flammable materials. Therefore, they need to be placed in the storage bin 1 for storage.

[0033] The storage bin 1 is as Figure 1As shown, the silo 1 is a cylindrical tank. Compared with the existing flat storage of flammable materials, the cylindrical tank can increase the storage capacity of flammable materials and reduce the floor area. However, there is a hidden danger of combustion of flammable materials in the storage of the silo 1. Based on this, in this embodiment, a dust removal component, a spraying component 3 and a steam distribution pipe 4 are newly added. Specifically, the dust removal component includes components such as a dust removal pump, a dust removal bag and a dust removal pipe 2, which can extract dust and particulate matter. Because in the process of transporting flammable materials, there must be flammable material dust in the air, which can become a combustion medium if it encounters a spark. This is also a flammable factor of flammable materials. The dust removal component can extract the flammable material dust into the dust removal bag. In this embodiment, the dust removal bag can be made of fireproof fabric to improve the fire safety performance. Further, the dust removal bag is provided with air holes to facilitate the extraction of air from the dust removal bag, but the flammable material dust is blocked in the dust removal bag. The dust removal pump can be a commercially available dust removal pump. The spraying component 3 includes a plurality of nozzles 31, and each nozzle 31 can be set according to actual needs. Preferably, the nozzles 31 are arranged at intervals along the circumference of the silo 1, and the spray openings of the nozzles 31 are arranged from top to bottom to expand the spraying area and improve the efficiency of fire extinguishing and dust removal. The steam distribution pipe 4 distributes steam evenly into the silo 1.

[0034] The temperature sensor 5 is arranged in the silo 1 and can monitor the temperature in the silo 1 in real time. The control unit is electrically connected to the temperature sensor 5, the dust removal component, the spraying component 3 and the steam distribution pipe 4, and controls the operation of dust removal, spraying and steam distribution according to the feedback signal of the temperature sensor 5 to keep the temperature in the silo 1 within a safe range.

[0035] Specifically, in use, the flammable materials for activated carbon production enter the silo 1 through the feed inlet 11. The dust removal pump extracts the dust in the silo 1 and is connected to the dust removal bag through the dust removal pipe 2. During the material transportation process, the dust removal component can remove the dust during material transportation. When a fire has occurred in the silo 1, the dust removal component can also extract the air and smoke in the silo 1 to reduce the oxygen content in the silo 1. Further, the nozzles 31 at the top can extinguish the flames in the silo 1 in time, and at the same time control the steam distribution pipe 4 to input steam into the silo 1 from bottom to top. The steam contains moisture, which can further increase the moisture in the silo 1 to slow down the fire, and at the same time guide the oxygen in the silo 1 to be extracted from the dust removal component, reducing the combustion risk of the silo 1 and ensuring the stability and safety of the production process.

[0036] In some embodiments, a support component is further included. The support component includes a plurality of feet 6, and the plurality of feet 6 are distributed along the circumference of the silo 1 and are arranged below the silo 1; the steam distribution pipe 4 is arranged within the surrounding area of the plurality of feet 6.

[0037] The support feet 6 can be made of steel I-beams, square tubes, round tubes and other steel pipes. The support feet 6 and the silo 1 can be fixedly connected by welding or locking. In some embodiments, a receiving protrusion is provided inside the support feet 6, and the silo 1 can be directly placed on the receiving protrusion to achieve a detachable connection between the silo 1 and the support feet 6.

[0038] In this embodiment, a plurality of support feet 6 are circumferentially distributed along the silo 1. As Figure 1 shown, after a plurality of support feet 6 lift and fix the silo 1, a space is vacated below the silo 1, which is denoted as the surrounding area. Then, a steam distribution pipe 4 can be arranged in this surrounding area. Steam is stored in the steam distribution pipe 4, improving the space utilization rate.

[0039] Please refer to Figure 2 , in some embodiments, the steam distribution pipe 4 includes a first main pipeline 41 and a plurality of first branch pipelines 42. The first branch pipelines 42 are distributed at the bottom of the silo 1 in a first preset manner, and the first branch pipelines 42 are communicated with the silo 1. The first main pipeline 41 is respectively communicated with the plurality of first branch pipelines 42, and the other end of the first main pipeline 41 is communicated with high-pressure steam.

[0040] In some embodiments, it further includes a first valve and a plurality of second valves. The first valve is communicated with the first main pipeline 41; each second valve is communicated with a first branch pipeline 42. The first valve can adjust the opening degree of the first main pipeline 41, and the second valve can adjust the opening degree of the first branch pipeline 42. In this embodiment, the first main pipeline 41 and the first branch pipelines 42 can be automatically controlled under the control of the control unit, realizing the automatic adjustment of the steam at the bottom of the silo 1 to meet the fire extinguishing requirements.

[0041] In some embodiments, a plurality of nozzles 31 are distributed at the top of the silo 1 in a second preset manner. The spraying assembly 3 further includes a water storage tank, a spray pipe 32 and a third valve. Water is contained in the water storage tank; one end of the spray pipe 32 is arranged inside the silo 1, the spray pipe 32 is separately communicated with the plurality of nozzles 31, and the other end of the spray pipe 32 protrudes outside the silo 1 and is communicated with the water storage tank; the third valve is arranged on the spray pipe 32. The water storage tank serves as the water supply source of the spraying assembly 3, which can effectively utilize water resources. By controlling the third valve, the water quantity and frequency of spraying can be accurately adjusted, avoiding waste of water. By distributing a plurality of nozzles 31 at the top of the silo 1 in a second preset manner, uniform distribution of spraying can be achieved. In this way, it can be ensured that all areas inside the silo 1 can be fully covered by spraying, improving the wetting effect and fire extinguishing efficiency.

[0042] In some embodiments, a drain outlet is further provided at the bottom of the silo 1, and the device further includes a drain pipe, which is connected to the drain outlet and is used to drain the water in the silo 1. In some scenarios, when the fire is too large and the spraying amount of the nozzle 31 is excessive, after the fire is extinguished, the nozzle 31 will continue to spray the flammable materials to increase the moisture content of the flammable materials. The setting of the drain outlet can timely drain the excess water in the silo 1, avoiding the state that the bottom of the flammable materials is completely immersed in water, which affects the production of activated carbon.

[0043] In some embodiments, a dust sensor 7 is further included. The dust sensor 7 is arranged in the silo 1 and is electrically connected to the control unit and also to the dust removal pump. The dust sensor 7 is a device for detecting and measuring the dust concentration in the air. It usually uses different working principles such as optical, electrochemical or gravimetric methods to achieve dust detection. For example, the dust sensor 7 made based on the optical working principle uses the principle of light scattering or absorption to measure the concentration of dust particles. Usually, a laser or LED emitter is used to emit a light beam, and the light signal scattered or absorbed by the dust is received by the receiver, and the dust concentration is calculated through signal processing. Another example is that the dust sensor 7 made based on the electrochemical working principle uses a chemical reaction to measure the dust concentration. The dust particles react with the surface of the electrode on the sensor, generating a current or potential change, and the dust concentration is calculated by measuring the current or potential change. The setting of the dust sensor 7 can detect the dust concentration in the silo 1, so as to facilitate the timely activation of the dust removal component and improve the safety probability.

[0044] The above technical solution provides a storage device for flammable materials in the production of activated carbon. The device includes a silo 1, a spraying component 3, a steam distribution pipe 4, a dust removal component, and a temperature sensor 5. Materials enter the interior of the silo 1 through the feed inlet 11. During the process of entering the silo 1, the dust in the falling process is extracted from the silo 1 by the dust removal component to prevent dust explosion. After the materials are stacked, through the temperature monitoring of the temperature sensor 5, when there is a fire or combustion, it will cause the temperature in the silo 1 to rise. When the temperature value in the silo 1 reaches a certain range, the control unit will turn on the spraying component 3. The spraying liquid passes through the spraying component 3 to the nozzle 31, and the tap water is evenly added to the silo 1 by the nozzle 31. At the same time, the bottom steam distribution pipe 4 is opened. After the steam is evenly distributed by the bottom steam distribution pipe 4, it is injected into the interior of the silo 1 to displace the oxygen in the silo 1 and extinguish the materials at the fastest speed. At the same time, the dust removal component starts to work, and the internal high-temperature and high-humidity gas is extracted from the silo 1, realizing the large-scale and long-term storage of materials. The device shown in this technical solution is reasonably set, has a low manufacturing cost, is safe and environmentally friendly. After the carbon materials enter the silo 1, the storage can be completed. The subsequent monitoring is realized by the overall temperature sensor 5 and the spraying component 3 using the control unit to complete the fire extinguishing automatically without the need for personnel to regularly open the observation port for detection. It solves the problem of spontaneous combustion during storage, improves the space utilization rate, can reduce the storage cost of carbonized materials per unit product, improves the safety factor, and achieves the purpose of safe production and energy conservation.
