Description
技术领域technical field
本发明涉及一种干燥装置，特别是一种碳分子筛干燥装置。The invention relates to a drying device, in particular to a carbon molecular sieve drying device.
背景技术Background technique
碳分子筛是一种新型的吸附剂，主要构成是具有高度发达孔结构的结晶炭和无定形炭。碳分子筛具有优良的微观反应活性和吸附性能，被广泛应用于混合气体分离，如制氮制氧。Carbon molecular sieve is a new type of adsorbent, mainly composed of crystalline carbon and amorphous carbon with highly developed pore structure. Carbon molecular sieves have excellent microscopic reactivity and adsorption properties, and are widely used in the separation of mixed gases, such as nitrogen and oxygen production.
碳分子筛的工艺流程主要包括预氧化，成型，干燥，炭化，活化和碳沉积。其中，干燥过程必须有效控制碳分子筛在之前工序吸收的水分，否则将影响活化效果，导致最终成品率下降。现有的碳分子筛干燥装置基本采用热气烘干的方式，即在烘干炉内流通热惰性气体的方式去除水分。由于干燥的最后阶段水分多存在碳分子筛的微观孔内，并且当碳分子筛材料堆积时内部气体流通不畅，因此这种干燥方式效率较低，并且这种烘干方式耗电量大。The process flow of carbon molecular sieve mainly includes pre-oxidation, forming, drying, carbonization, activation and carbon deposition. Among them, the drying process must effectively control the moisture absorbed by the carbon molecular sieve in the previous process, otherwise the activation effect will be affected, resulting in a decrease in the final yield. The existing carbon molecular sieve drying device basically adopts the method of hot gas drying, that is, the way of circulating hot inert gas in the drying furnace to remove moisture. Since most of the moisture in the final stage of drying exists in the microscopic pores of the carbon molecular sieve, and when the carbon molecular sieve material is accumulated, the internal gas circulation is not smooth, so this drying method is inefficient and consumes a lot of power.
发明内容Contents of the invention
本发明的目的在于，提供碳分子筛干燥装置。本发明具有干燥效率高，耗电量低的特点。The object of the present invention is to provide a carbon molecular sieve drying device. The invention has the characteristics of high drying efficiency and low power consumption.
本发明的技术方案：碳分子筛干燥装置，包括干燥筒，干燥筒外壁设有微波发生装置，干燥筒内设有旋转式阻网，干燥筒经外壁齿轮与电机上的电机齿轮相连，干燥筒一端通过一号旋转支架连接进料口，进料口上端设有料斗，进料口侧旁设有风机，进料口下端设有氮气预热进气装置，干燥筒另一端通过二号旋转支架与出料口连接，出料口上端设有出出风口。The technical scheme of the present invention: the carbon molecular sieve drying device includes a drying cylinder, the outer wall of the drying cylinder is provided with a microwave generating device, the drying cylinder is provided with a rotating resistance net, the drying cylinder is connected with the motor gear on the motor through the gear on the outer wall, and one end of the drying cylinder is The feed inlet is connected through the No. 1 rotating bracket. The upper end of the feed inlet is equipped with a hopper, the side of the feed inlet is equipped with a fan, and the lower end of the feed inlet is equipped with a nitrogen preheating air intake device. The other end of the drying cylinder is connected with the No. 2 rotating bracket. The discharge port is connected, and the upper end of the discharge port is provided with an air outlet.
前述的碳分子筛干燥装置，所述氮气预热进气装置与进料口连接处设有预热进气阀门，料斗与进料口连接处设有料斗阀门，出风口与出料口连接处设有出风口阀门，出料口末端设有出料口阀门。In the aforementioned carbon molecular sieve drying device, a preheating inlet valve is provided at the connection between the nitrogen preheating inlet device and the feed port, a hopper valve is provided at the connection between the hopper and the feed port, and a valve is provided at the connection between the air outlet and the discharge port. There is an air outlet valve, and the end of the outlet is provided with an outlet valve.
与现有技术相比，本发明在干燥筒内壁连通微波发生装置，通过微波使碳分子筛微孔内的水分活跃加剧，逸出微孔。干燥筒外壁设有齿轮，齿轮又与电机齿轮啮合，干燥筒可以在电机的带动下旋转。由此，微波干燥后，在往干燥筒内通热氮气的同时旋转干燥筒使热氮气与碳分子筛充分接触，可以有效带走水汽。在本发明中，热氮气仅起到辅助干燥，运输水汽的作用，所以不需要长时间加热。因此，本发明具有干燥效率高，耗电量低的特点。Compared with the prior art, in the present invention, the inner wall of the drying cylinder is connected with a microwave generating device, and the moisture in the micropores of the carbon molecular sieve is activated and intensified by the microwaves, and escapes from the micropores. The outer wall of the drying cylinder is provided with a gear, and the gear meshes with the motor gear, and the drying cylinder can rotate under the drive of the motor. Therefore, after microwave drying, the drying cylinder is rotated while passing hot nitrogen gas into the drying cylinder to make the hot nitrogen gas fully contact with the carbon molecular sieve, which can effectively take away the water vapor. In the present invention, the hot nitrogen only plays the role of assisting drying and transporting water vapor, so it does not need to be heated for a long time. Therefore, the present invention has the characteristics of high drying efficiency and low power consumption.
