Description

Technical Field

[0001] The utility model relates to a device for post-treatment in the preparation process of a platinum-carbon catalyst. Technical Background

[0002] The carbon-supported platinum (Pt / C) catalyst for hydrogen fuel cells is currently a widely used catalyst, and most of them are prepared by the polyol reduction method. Its conventional process includes: batching, slurry adjustment, pretreatment, heating reaction, cooling, solid-liquid separation, and post-treatment. The purpose of the post-treatment is to remove residual high-boiling alcohol solvent substances, improve the cleanliness of the platinum particle surface, and thus improve its catalytic activity and stability. The complete removal of the solvent can ensure the product quality. The platinum-carbon catalyst is a dangerous product such as a flammable solid and an oxidant. It requires an oxygen-free environment during the high-temperature post-treatment process, and the platinum-carbon catalyst after the post-treatment is extremely prone to spontaneous combustion when it comes into contact with oxygen in the air instantly. Currently, a tube furnace is often used in the laboratory for post-treatment. However, the tube furnace cannot quantitatively analyze the gas composition during the post-treatment process. Starting the post-treatment when oxygen is not completely exhausted easily causes the catalyst to be oxidized. The small processing capacity of the tube furnace also limits the production of the catalyst. After the post-treatment, the temperature and oxygen concentration when the catalyst comes into contact with oxygen cannot be controlled, resulting in the catalyst after the post-treatment being extremely prone to spontaneous combustion and losing its activity.

[0009] Outside the box body of the heating box 2: An air compressor 10, an oxygen concentration controller 11, a temperature controller 12, and a pressure controller 13 are provided above the heating box 2;

[0010] The air inlet pipe 1-1 is connected to the air inlet box 5 through the safety valve 1-2, the pressure controller 13, and the electronically controlled gas flow meter 1-3. The air inlet box 5 is communicated with the heating box 2 through a gas outlet; The inert gas storage tank is connected to the air inlet pipe 1-1. The inert gas flows through the electronically controlled gas flow meter 1-3 and is input into the air inlet box 5, and then further flows into the heating box 2 and the load box 3. The inert gas is continuously introduced to reduce the oxygen concentration in the heating box 2;

[0011] The air compressor 10 is also connected to the air inlet box 5 and inputs air into the air inlet box 5 through the air compressor 10 after the post-treatment ends; When the post-treatment ends, as the temperature continuously drops, air is slowly injected into the air inlet box 5 through the air compressor 10 and is mixed with the inert gas therein in different proportions to slowly increase the oxygen concentration in the heating box 2 and the load box 3, ensuring that the oxygen concentration at this temperature cannot cause the platinum-carbon catalyst to self-ignite;

[0012] The oxygen concentration controller 11 is signal-connected to the self-priming oxygen concentration monitor 8, the electronically controlled gas flow meter 1-3, and the air compressor 10; The oxygen concentration controller 11 receives the oxygen concentration data of the oxygen concentration monitor 8 in real time and controls the start and stop of the air compressor 10 and the switch of the electronically controlled gas flow meter 1-3;

[0015] Furthermore, a condenser 15 is also provided at the rear side of the heating chamber 2; the condenser is composed of a compressor, a condensing pipe and radiating fins; when the air cooling reduces the temperature to 120 °C, the condenser 15 is started to accelerate the cooling, so that the temperature is reduced below the normal temperature, thereby reducing the spontaneous combustion risk of the catalyst.

[0016] Furthermore, the electronic control type gas flow meters 1-3 are 200L gas flow meters and 50L gas flow meters, which are connected to the intake chamber 5 through their respective gas paths to accurately control the oxygen concentration in the intake chamber and save the usage amount of inert gas.

[0017] Furthermore, the material of the heating chamber 2 is stainless steel.

[0018] Furthermore, the material of the carrier box 3 and its internal accessories is stainless steel.

[0019] Furthermore, a solenoid valve 3-4 is also provided at the door 3-2 of the carrier box 3 to ensure the sealing between the carrier box and the outside.

[0020] The working principle of the automatic safety platinum-carbon catalyst batch post-treatment device of the present utility model is as follows:

[0021] 1. Classify and place the platinum-carbon catalyst after solid-liquid separation or drying on the carrier partition board 3-2 of the carrier box 3, close the door 3-1 to keep it sealed, and set the oxygen content, temperature and time of the post-treatment on the display screen 1-4 of the central control system; control the gas pressure controller 13 within the pressure range of 4-6 MPa; after starting the post-treatment program, the oxygen concentration controller 11 monitors the oxygen concentration in the heating chamber 2. When the oxygen concentration controller 11 recognizes that the oxygen concentration in the heating chamber 2 is higher than the preset post-treatment oxygen concentration, it controls the electronic control type gas flow meters 1-3 to start, and introduces inert gas into the heating chamber 2 at a large flow rate to reduce the oxygen concentration, and starts the circulation fan 6 to ensure uniform gas distribution in the heating chamber 2; the exhaust pipe 7 continuously discharges a small amount of gas from the box to achieve the balance of intake and exhaust, prevent air backflow, and ensure that the oxygen content reaches the preset value; when the oxygen concentration controller 11 recognizes that the oxygen concentration in the heating chamber 2 monitored by the self-priming type oxygen concentration monitor 8 reaches the preset heat treatment oxygen concentration, it controls the electronic control type gas flow meters 1-3 to continuously introduce inert gas into the heating chamber 2 at a small flow rate, saving the use of inert gas while ensuring a low oxygen content.

[0022] 2. When the oxygen concentration in the heating box 2 reaches the preset heat treatment oxygen concentration, the temperature controller 12 controls the heater 4 to continuously heat the inside of the heating box 2 and maintains the start of the circulation fan 6 to ensure the flow of hot gas in the heating box 2, thereby ensuring the uniformity of the temperature and oxygen concentration inside the box; the temperature sensor 9 monitors the temperature inside the heating box 2 in real time. When the temperature reaches the preset post-treatment temperature, the temperature controller 12 controls to reduce the power of the heater 4 to maintain the temperature inside the heating box 2 at the preset post-treatment temperature; during the whole process, the self-priming oxygen concentration monitor 8 monitors the oxygen concentration inside the heating box 2 in real time; when the gas dynamic balance inside the heating box 2 is broken and the oxygen concentration exceeds 120% of the preset value, the oxygen concentration controller 11 starts an emergency deoxygenation procedure: that is, controls the electronically controlled gas flowmeter 1-3 to open and introduce inert gas into the heating box 2 at a large flow rate to drive away oxygen, so as to ensure that the oxygen concentration never exceeds the preset value during the whole post-treatment process, so that the platinum-carbon catalyst will not be oxidized; when the self-priming oxygen concentration monitor 8 monitors that the oxygen concentration inside the heating box 2 returns within the preset value, the oxygen concentration controller 11 controls the electronically controlled gas flowmeter 1-3 to close.

[0023] 3. When the post-treatment reaches the preset time, the temperature controller 12 controls to turn off the heater 4 and starts the fan 14 to cool the back of the heating box 2 by air cooling. At the same time, the temperature controller 12 controls to maintain the operation of the circulation fan 6 to ensure the heat convection inside the heating box 2 and quickly cool the heating box 2; when the temperature sensor 9 monitors that the temperature inside the heating box 2 drops to a certain extent, the temperature controller 12 controls the condenser 15 to turn on to cool the heating box 2. The addition of the condenser 15 can not only play a role in quickly cooling, but also reduce the temperature inside the whole heating box 2 below 15°C. At this temperature, the risk of spontaneous combustion of the platinum-carbon catalyst in contact with air will be greatly reduced.

[0024] Similarly, during the whole process, the self-priming oxygen concentration monitor 8 monitors the oxygen concentration inside the heating box 2 in real time. When it exceeds a certain proportion of the preset value, the oxygen concentration controller 11 will start an emergency deoxygenation procedure and cycle the above process to ensure that the catalyst is under safe temperature and safe oxygen concentration conditions throughout the process;

[0025] IV. When the temperature controller 12 recognizes that the temperature in the heating chamber 2 monitored by the temperature sensor 9 reaches 15 °C or lower, the oxygen concentration controller 11 controls the air compressor 10 and the electronic gas flowmeter 1-3 to start. At the same time, the oxygen concentration monitor 8 monitors the oxygen concentration in the heating chamber 2 in real time. According to the set oxygen content increase rate, through the PID control system, the flow rate of the air compressor 10 and the electronic gas flowmeter 1-3 are controlled, so that air and inert gas are evenly mixed in the intake chamber 5 and then enter the heating chamber 2, preventing the oxygen with a relatively high concentration in the air from directly contacting the unprocessed catalyst, thereby controlling the oxygen concentration in the heating chamber 2 to gradually rise; the processed platinum-carbon catalyst slowly reacts with low-concentration oxygen at low temperature, and gradually increases the oxygen concentration in contact with the platinum-carbon catalyst, greatly reducing the risk of spontaneous combustion when the catalyst contacts air instantaneously at the end of the post-treatment. Gradually reducing the temperature and slowly contacting the oxygen in the air are the keys to preventing the platinum-carbon catalyst from being oxidized or spontaneously combusted. When the oxygen volume percentage increases to 20%, the catalyst can directly contact air, and the platinum-carbon catalyst in the carrier box 3 is taken out to complete the post-treatment of the platinum-carbon catalyst.

[0026] When the automatic and safe batch platinum-carbon catalyst post-treatment device of the present utility model is working, the heater 4, the self-priming oxygen concentration monitor 8, the temperature sensor 9, the gas flowmeter 10, the oxygen concentration controller 11, and the temperature controller 12 cooperate to control the oxygen concentration and temperature in the heating chamber 2. The digital controllability of the oxygen content during the heat treatment of the platinum-carbon catalyst can ensure that the post-treatment conditions are always the set optimum, so that the platinum-carbon catalyst will not be oxidized and its performance will not be reduced.

[0027] When the automatic and safe batch platinum-carbon catalyst post-treatment device of the present utility model is working, the volume of its carrier box 3 and the setting of the carrier partition board 3-2 can simultaneously process a variety of different catalysts within 1 kg, greatly improving the production efficiency of the catalyst.

[0028] When the automatic and safe batch platinum-carbon catalyst post-treatment device of the present utility model is working, ① the setting of the condenser 15 can enable the platinum-carbon catalyst itself to quickly drop to a relatively low temperature, so that the platinum-carbon catalyst is temporarily dormant; ② the coordinated control of the self-priming oxygen concentration monitor 8, the intake chamber 9, the air compressor 12, and the oxygen concentration controller 11 allows the platinum-carbon catalyst to slowly contact oxygen controllably after the post-treatment ends. These two points greatly reduce the risk of spontaneous combustion of the dangerous goods platinum-carbon catalyst, which is a flammable solid and a spontaneous combustion solid.

[0029] The automatic and safe batch platinum-carbon catalyst post-treatment device of the present utility model can be used in the field of catalyst preparation. Description of the Drawings
