Referring to fig. 1 and 2, the apparatus 100 for preparing cobaltosic oxide includes a cobalt chloride solution storage tank 10, a cobalt chloride solution pump 11, an atomizing nozzle 12, an evaporator 13, a heater 14, a compressed air supply source 15, a receiving buffer tank 16, a cyclone 17, a dust collector 18, and a suction fan 19.
The cobalt chloride solution storage tank 10 is used for storing a cobalt chloride solution formed by water and cobalt chloride.
The cobalt chloride solution pump 11 is connected between the cobalt chloride solution storage tank 10 and the atomizing nozzle 12, and the cobalt chloride solution pump 11 is used for pumping the cobalt chloride solution in the cobalt chloride solution storage tank 10 to the atomizing nozzle 12.
The atomizing nozzle 12 is installed on the top of the evaporator 13 and extends into the inner cavity 131 of the evaporator 13, and the atomizing nozzle 12 is used for atomizing the received cobalt chloride solution into water mist and entering the top of the atomizing nozzle 12.
The heater 14 covers the periphery of the evaporator 13, and the heater 14 is used for heating the evaporator 13 to form a high-temperature environment in the inner cavity 131 of the evaporator 13.
The compressed air supply source 15 is used to supply compressed air to the top of the evaporator 13 so that oxygen in the compressed air reacts with cobalt chloride and water in the water mist-like cobalt chloride solution to form cobaltosic oxide powder and hydrogen chloride gas in the high-temperature environment of the inner cavity 131 of the evaporator 13.
The material receiving buffer tank 16 is connected below the bottom of the evaporator 13, the cyclone separator 17 is connected between the material receiving buffer tank 16 and the dust remover 18, and the dust remover 18 is connected between the cyclone separator 17 and the suction fan 19.
The suction fan 19 is connected to the evaporator 13 via the dust collector 18, the cyclone 17, and the material receiving buffer tank 16 to generate a negative pressure in the inner cavity 131 of the evaporator 13.
The material receiving buffer tank 16 is used for receiving cobaltosic oxide powder and hydrogen chloride gas formed from the evaporator 13 under the negative pressure formed by the suction fan 19.
The cyclone 17 is configured to receive the hydrogen chloride gas in the material receiving buffer tank 16 and the cobaltosic oxide powder at the bottom of the material receiving buffer tank 16 under the negative pressure formed by the suction fan 19, so as to separate the received hydrogen chloride gas and the cobaltosic oxide powder in the cyclone 17, the separated cobaltosic oxide powder is collected in the storage tank 171 of the cyclone 17, and the separated hydrogen chloride gas and a part of the cobaltosic oxide powder carried by the hydrogen chloride gas are supplied to the dust remover 18 under the negative pressure formed by the suction fan 19.
The dust collector 18 is configured to receive the hydrogen chloride gas supplied by the cyclone separator 17 and the part of the cobaltosic oxide powder carried by the hydrogen chloride gas under the negative pressure formed by the suction fan 19, separate the cobaltosic oxide powder from the hydrogen chloride gas by filtering, pump the filtered hydrogen chloride gas away by the suction fan 19 under the negative pressure formed by the suction fan 19, and collect the filtered cobaltosic oxide powder in the storage tank 181 of the dust collector 18.
In the apparatus 100 for preparing cobaltosic oxide of the present disclosure, the cobalt chloride solution pumped by the cobalt chloride solution pump 11 from the cobalt chloride solution storage tank 10 enters the atomizing nozzle 12 and is atomized into water mist at the atomizing nozzle 12, and then enters the inner cavity 131 of the evaporator 13, while the oxygen supplied by the compressed air supply source 15 enters the inner cavity 131 of the evaporator 13 through the top of the evaporator 13, and under the high temperature environment formed by heating the evaporator 13 in the inner cavity 131 of the evaporator 13 by the heater 14, the oxygen in the compressed air reacts with the cobalt chloride and the water in the water mist-like cobalt chloride solution to form cobaltosic oxide powder and hydrogen chloride gas under the high temperature environment, and the chemical equation of the reaction is:
thus, a cobaltosic oxide powder was prepared.
In the cobaltosic oxide preparation device 100 disclosed by the invention, the atomizing nozzle 12 is adopted for atomizing the cobalt chloride solution, so that the atomized cobalt chloride solution can be better dispersed and has a larger contact area, and can be rapidly mixed and reacted with high-speed oxygen provided by compressed air in a large area, and the preparation efficiency of cobaltosic oxide is improved.
In the cobaltosic oxide preparation device 100 disclosed by the invention, the three-stage collection of cobaltosic oxide powder is realized through the material receiving buffer tank 16, the cyclone separator 17 and the dust remover 18, so that the yield of cobaltosic oxide is improved.
In the apparatus 100 for producing cobaltosic oxide of the present disclosure, the suction fan 19 is used to generate the negative pressure, so that the suction conveying force required for the three-stage collection of the cobaltosic oxide powder is achieved, and the suction force for the hydrogen chloride gas is also achieved, and after the cobaltosic oxide powder is collected at the three stages, the hydrogen chloride gas is discharged by the suction fan 19 and is introduced into the spray tower 21 to be described later for tail gas treatment, thereby achieving the environmentally friendly discharge of the tail gas.
In one example, the evaporator 13 is made of quartz glass. The evaporator 13 is resistant to high temperature and corrosion, and prevents substances of the evaporator 13 from falling off due to high temperature and/or corrosion and being introduced into the cobaltosic oxide powder as impurities.
In one example, the heater 14 is an electric heater. In one example, the temperature of the high temperature environment is 800 ℃ to 1000 ℃.
The flow rate of the compressed air supplied by the compressed air supply source 15 is matched to the atomization amount of the atomizing nozzle 12 so as to provide the reactant exactly as in the aforementioned reaction formula, but it is also feasible to use a slight excess of oxygen supplied by the compressed air since the compressed air supply technology is also mature.
In the apparatus 100 for preparing cobaltosic oxide of the present disclosure, in order to separate cobaltosic oxide powder, wind pressure is provided by the suction fan 19, and in order to avoid the wind pressure from affecting the preparation of cobaltosic oxide in the evaporator 13, the material receiving buffer tank 16 is connected to the bottom of the evaporator 13. Thus, referring to fig. 1, in one example, the receiving buffer tank 16 is a conical funnel. The cobaltosic oxide powder generated from the reaction of the evaporator 13 firstly passes through the material receiving buffer tank 16 and is buffered and accumulated in the conical funnel, so that the direct influence of the wind pressure in the cobaltosic oxide preparation device 100 on the evaporator 13 is avoided.
Due to the conical funnel structure of the material receiving buffer tank 16, the cobaltosic oxide powder and the hydrogen chloride gas at the lower layer in the material receiving buffer tank 16 enter the cyclone separator 17 under the negative pressure formed by the suction fan 19, and the cobaltosic oxide powder at the upper layer in the material receiving buffer tank 16 is accumulated in the material receiving buffer tank 16, so that the cobaltosic oxide powder and the hydrogen chloride gas just coming out of the evaporator 13 need a certain time to be cooled. Thus, in an embodiment, referring to fig. 1, the material receiving buffer tank 16 is provided with an air inlet pipe 161, the air inlet pipe 161 is provided with a filter 162, the air inlet pipe 161 is communicated with the outside, and the air inlet pipe 161 is used for introducing fresh air from the outside into the material receiving buffer tank 16 under a negative pressure formed by the suction fan 19 to cool the cobaltosic oxide powder and the hydrogen chloride gas in the material receiving buffer tank 16 (i.e., the cobaltosic oxide powder and the hydrogen chloride gas just coming out of the evaporator 13), thereby preventing high temperature damage to downstream equipment (the material receiving buffer tank 16, the cyclone separator 17, the dust remover 18, the suction fan 19, and connecting pipes (not shown) therebetween) caused by high temperature of the cobaltosic oxide powder, the hydrogen chloride gas and other gases just coming out of the evaporator 13. The use of the filter 162 avoids the introduction of particulate matter contained in the fresh air as impurities into the cobaltosic oxide powder in the receiving buffer tank 16.
The receiving buffer tank 16 is made of stainless steel, but is not limited thereto, and the receiving buffer tank 16 may be formed of a material having any suitable performance requirement (e.g., strength, corrosion resistance, etc.).
As shown in fig. 1, the cyclone 17 includes an upper cylindrical portion 172, a lower tapered portion 173, a discharge valve 174, and a storage tank 171, which are sequentially connected in the up-down direction, and the discharge valve 174 controls the on-off between the lower tapered portion 173 and the storage tank 171 and the dropping of the tricobalt tetroxide powder depending on whether the weight of the tricobalt tetroxide powder accumulated in the lower tapered portion 173 reaches an open value. The discharging valve 174 is opened and closed once by the weight of the accumulated cobaltosic oxide powder, so that the storage tank 171 below the discharging valve 174 of the cyclone 17 collects the accumulated cobaltosic oxide powder and is isolated from the cyclone 17, thereby improving the collection rate of the cobaltosic oxide powder at the cyclone 17.
The cyclone 17 is made of stainless steel, but is not limited thereto, and the cyclone 17 may be formed of a material having any suitable performance requirements (e.g., strength, corrosion resistance, etc.).
The dust catcher 18 is made from stainless steel sheet material, but is not so limited and the dust catcher 18 may be formed from a material having any suitable performance requirements (e.g., strength, corrosion resistance, etc.). In one example, the dust separator 18 is also in controlled communication with the compressed air supply 15 to purge the dust separator 18 before and after operation with compressed air provided by the compressed air supply 15.
The suction fan 19 is used to generate a negative pressure value, so that the suction does not affect the reaction of forming the cobaltosic oxide in the cavity 131 of the evaporator 13, that is, the suction speed is matched with the amount of the cobaltosic oxide, thereby preventing the water-mist cobalt chloride solution which does not have the reaction to be sucked into the water-mist cobalt chloride solution.
Referring to fig. 1, in one example, the apparatus 100 for preparing cobaltosic oxide further comprises a cooling water line 20, the cooling water line 20 passing through the atomizing nozzle 12, the cooling water line 20 being used to cool the atomizing nozzle 12. Since the evaporator 13 is located at a high temperature, the atomizing nozzle 12 is cooled down by the cooling water line 20 in order to prevent the atomizing nozzle 12 from being damaged by the high temperature.
Referring to fig. 1, in an example, the apparatus 100 for preparing cobaltosic oxide further includes a spray tower 21, the spray tower 21 is connected to the suction fan 19, and the spray tower 21 is used for treating the hydrogen chloride gas sucked out by the suction fan 19. The sucked hydrogen chloride gas is sprayed by the spray tower 21, and the tail gas is discharged in an environment-friendly way.
The above detailed description is used to describe exemplary embodiments, but is not intended to limit the combinations explicitly disclosed herein. Thus, unless otherwise specified, various features disclosed herein can be combined together to form a number of additional combinations that are not shown for the sake of brevity.
