Description

Technical Field

[0001] The present invention relates to the technical field of steel slag cooling, and in particular to an explosion-proof system for a steel slag hot stewing container, and more specifically to an explosion-proof system using a hydrogen removal device in order to effectively prevent explosion accidents caused by the accumulation of hydrogen during the steel slag hot stewing cooling process. The hydrogen removal device can effectively remove even low-concentration hydrogen, thereby preventing hydrogen accumulation in advance. Background Art

[0002] At present, steel slag is mainly cooled by water spraying, which has good cooling effect and fast speed. However, hydrogen explosive gas is easily produced during the cooling process, which brings safety hazards to production.

[0003] For example, the hot stewing treatment process of steel slag with mature technology is mainly characterized by high-temperature liquid steel slag (temperature 1200℃~1600℃) discharged from the steelmaking furnace and loaded into the slag pot, which is directly poured into the hot stewing device through the slag pot, and then covered and sprayed with water for hot stewing. The process is simple, and after treatment, it has the advantages of good steel slag pulverization effect and high metal recovery rate. However, hydrogen will be generated during the hot stewing process, which often causes explosion danger. In serious cases, the stewing cover will be blown off, causing production facilities and personal injury.

[0004] Hydrogen is the most explosive gas. Its mixture with O2 has the risk of explosion in a wide concentration range. The explosive concentration range in oxygen is (4%~94%), and the explosive concentration range in air is (4%~75%), and the explosion power is enormous.

[0005] The existing slag hot stewing pool stewing cover device includes a cover body, a pressure relief protection device, a cooling water spraying device and a water seal groove, etc. The explosion-proof measure is mainly the pressure relief protection device, which is the main means to prevent explosion during the steel slag hot stewing process. According to the usage in recent years, since the hydrogen explosion during slag stewing is extremely powerful, although the pressure relief protection device on the stewing cover device has played a partial role, the effect is still not ideal.

[0006] Chinese patent CN201220524227.2 discloses a safe hot stewing cover device. Since an explosion protection device is provided on the stewing cover device as the last line of safety, if the pressure relief protection device on the stewing cover device fails, the explosion protection device can still play a role to improve the safety index of the hot stewing treatment of steel slag.

[0007] Chinese patent CN202020178753.2 discloses an explosion relief device and a steel slag hot stewing treatment equipment using the same. The explosion relief device comprises: a shell, the bottom wall of the shell is used to be fixed and sealed with the equipment to be vented, and an opening is formed on the top wall and / or side wall of the shell; and a bursting disc, which is sealed and detachably fixed at the opening of the shell. Among them, the bursting disc is configured as follows: at the working temperature, when the air pressure in the equipment to be vented makes the pressure inside the shell greater than the working pressure of the bursting disc, the bursting disc ruptures. It is hoped that the explosion risk of steel slag hot stewing treatment equipment can be reduced by the explosion relief device.

[0008] The above patented technologies all achieve the purpose of improving the safety of hot stewing treatment of steel slag by means of pressure relief, that is, they involve pressure relief protection devices, but there is still a risk of the cover being blown off, posing a threat to personal and environmental safety.

[0009] In view of the shortcomings of the prior art, technicians in this field are in urgent need of seeking an explosion-proof system that can effectively reduce the risk of explosion in steel slag hot stewing treatment equipment. Summary of the invention

[0030] Effects of the Invention]

[0031] As described above, according to the explosion-proof system of the steel slag hot stew container of the present invention, the hydrogen in the hot stew container is collected and oxidized to remove hydrogen, thereby fundamentally preventing explosions caused by hydrogen. The entire reaction process is stable, safe and pollution-free.

When the hydrogen content is low and the oxygen content is high in the initial stage, hydrogen removal is mainly carried out in the catalytic reaction zone to prevent internal hydrogen and oxygen accumulation and explosion. When the hydrogen content is high in the middle and late stages, hydrogen removal is mainly carried out in the electrochemical reaction zone to achieve the purpose of rapidly reducing the hydrogen concentration and avoid the occurrence of hydrogen leakage and explosion.

[0033] In addition, according to an explosion-proof system for a steel slag hot stewing container of the present invention, the hydrogen concentration in the hot stewing container is monitored, safe production operations are guided, explosions caused by hydrogen are effectively prevented, and the safety factor is improved.

[0034] In addition, in order to prevent hydrogen explosion, the previous steel slag cooling process will release the generated hydrogen into the atmosphere. The discharged hydrogen directly enters the stratosphere, which may disrupt the formation of ozone, and may further cause a larger and longer-lasting ozone hole, threatening the human living environment. According to the explosion-proof system of the steel slag hot stewing container of the present invention, the hydrogen discharged into the atmosphere is effectively harmless from the source, and the reaction generates water, which has a positive significance for protecting the environment.

[0064] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0065] like Figure 1-2 As shown, it is an explosion-proof system for a hot stew container using a dehydrogenation device according to the present invention, which comprises: a hydrogen collecting device 1, which is arranged on the upper part of the hot stew container 5; a dehydrogenation device 2 with a built-in catalyst, when a hydrogen-containing fluid is collected by the hydrogen collecting device, it is introduced into the dehydrogenation device, and the dehydrogenation device oxidizes the hydrogen contained in the fluid to remove the hydrogen; an energy release device 3, when hydrogen is captured by the dehydrogenation device for oxidation, the energy release device connected to the dehydrogenation device converts and releases the energy of the oxidation reaction; a safety indicator 4, when hydrogen is oxidized by the dehydrogenation device 3 and the energy release device converts and releases energy, the safety indicator displays the hydrogen explosion safety index in the hot stew container.

[0066] In addition, the hydrogen collection device 1 includes: a hydrogen inlet 11, which is used to introduce the gas 1# fluid containing hydrogen inside the hot stewing container; after the 1# fluid is introduced, it first passes through the purifier 12 to filter out harmful impurities such as dust to reduce the harm to the subsequent catalyst; after purification, the 1# fluid enters the 1# hollow body 14 and begins to gather; the sensor unit 13 is used to detect the hydrogen concentration, and when the hydrogen concentration exceeds 4% or even higher, the sensor unit displays a danger signal; the emergency discharge port 15 is used to quickly discharge hydrogen in an emergency, and the emergency discharge port 15 is in a closed state when the system of the present invention works normally. When the hydrogen concentration detected by the sensor unit 13 exceeds the predetermined concentration and the installation indicator 4 shows that the hydrogen concentration is low, it is determined that the dehydrogenation device has a fault, and the remaining hydrogen in the hydrogen collection device 1 is sucked from the emergency discharge port to a safe area for discharge or storage. Or if other emergency states are considered during production, the emergency discharge port 15 can also be opened to discharge hydrogen in an emergency. Since hydrogen is light, and the hydrogen collecting device 1 is located at the top of the hot stew container and is gas-connected, hydrogen automatically gathers at the top of the hydrogen collecting device 1 according to its own weight, and after purification, other gases can be squeezed to the hydrogen inlet 11. Preferably, the working pressure in the hot stew container is 5Pa~2Mpa.

[0067] In addition, the dehydrogenation device 2 with a built-in catalyst includes: a catalytic reaction zone 21, which contains a 1# catalyst. The hydrogen coming out of the hydrogen collection device first catalytically oxidizes the hydrogen contained in the fluid to cause low-temperature catalytic combustion of the hydrogen-containing gas; an electrochemical reaction zone having an anode 22, a proton exchange membrane 23 and a cathode 24, which can further perform an electrochemical catalytic reaction on the hydrogen that has not been catalyzed to participate in the oxidation reaction. The anode 22 and the cathode 24 contain a 2# catalyst. The hydrogen undergoes a primary cell reaction under the action of the 2# catalyst. The hydrogen atom first becomes a positively charged hydrogen ion and a negatively charged electron, wherein the hydrogen ion reaches the cathode through the electrolyte, and the negatively charged electron reaches the cathode through the external circuit, and finally the hydrogen ion combines with the oxygen atom near the cathode to form water; a water discharge port 25 is used to smoothly discharge the water generated by the reaction.

[0068] In addition, the energy release device 3 includes: an oxygen inlet 31, which is used to introduce oxygen to provide oxygen for the dehydrogenation device; a 2# hollow body 34, which extends from the inlet and collects a 2# fluid containing oxygen; preferably, the 2# fluid here is air; the electric energy release system includes an electric heating wire 32 and a fan 33, which are connected to the positive electrode and the negative electrode in the dehydrogenation device to form an electric circuit to convert the electric energy generated in the dehydrogenation device into kinetic energy and thermal energy for release; a 2# fluid outlet 35, which timely guides the fluid and reactants after the reaction out of the device; the fan is located inside the 2# hollow body 35, and is used to drive the fluid flow in the 2# hollow body to increase the oxygen flow near the negative electrode, thereby accelerating the hydrogen-oxygen reaction effect; the electric heater part is located inside the 2# hollow body 35, and generates a pressure difference and a chimney effect by heating the nearby gas, driving the air flow in the 2# hollow body to increase the oxygen flow near the negative electrode, thereby accelerating the hydrogen-oxygen reaction effect.

[0069] In addition, the safety indication device 4 includes a voltage detector and an indicator light. The voltage detector is connected in parallel to the electrical circuit of the dehydrogenation device to detect the voltage between the anode and the cathode, and indicates the hydrogen status in the hot stew container by conversion. The indicator light is connected in series to the electrical circuit of the dehydrogenation device. When hydrogen and oxygen react, current is generated, and the indicator light is on. At this time, opening the hot stew container is an unsafe state. When the indicator light is not on and the sensor unit 13 shows that the hydrogen concentration is less than 4%, the hot stew container can be opened.

[0070] In addition, in the catalyst reaction zone, the 1# catalyst is composed of a honeycomb structure with multiple holes, connected to the interior of the 1# hollow body 14. The main carrier of the 1# catalyst is Al2O3, and the active component is the precious metal Pd, with a loading amount of 0.1%-5%.

[0071] In addition, in the electrochemical reaction zone, the anode and cathode electrodes contain a 2# catalyst, and the main active component of the 2# catalyst electrode is a platinum alloy, preferably PtCo / C in this case, with a platinum loading of 0.02mg-1g / cm2.

[0072] In summary, the present invention has been described with reference to the accompanying drawings with a focus on preferred embodiments, but it is obvious to those skilled in the art that various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention is determined by the claims set forth in the claims so as to include these numerous modification examples.
