Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
A nozzle assembly 10 for a reactor according to an embodiment of the first aspect of the invention is described below with reference to the accompanying drawings. The nozzle assembly 10 for a reactor is adapted to be mounted at an inlet for process air or combustible gas of a smelting reactor (e.g., a side-blown smelting furnace, a side-blown reduction furnace) for blowing the process air or combustible gas into the smelting reactor.
As shown in fig. 1 to 6, a nozzle assembly 10 for a reactor according to an embodiment of the present invention includes: a nozzle body 100, a tee 200, and a lance 300.
Specifically, the nozzle body 100 has a passage 101 penetrating both ends. A tee 200 is mounted at the outer end of the nozzle body 100, the tee 200 having a process air inlet 201 and an outer port 202 communicating with the passageway 101, respectively, and a control member 203 is provided in the tee 200 adjacent the outer port 202. Here, the outer end of the nozzle body 100 refers to an end of the nozzle body 100 located outside the reactor. The spray gun 300 has an inserted state in which the spray gun 300 is inserted in the passage 101 by the outer port 202 and an extracted state in which the spray gun 300 allows the control member 203 to block off the outer port 202. The inner end of the spray gun 300 is provided with a self-damage piece 301, the self-damage piece 301 has a blocking state and a conducting state, and the self-damage piece 301 blocks the inner end of the spray gun 300 in the blocking state and conducts the inner end of the spray gun 300 in the conducting state.
The self-damaged part 301 may be configured as a fusible part or a flammable part, so that the self-damaged part 301 has certain strength and is easy to melt or burn after receiving high temperature, and the self-damaged part 301 may be made of low-melting-point metal (such as lead, etc.), hard plastic, wood, etc., so as to be easily damaged under the action of the melt.
The use of the nozzle assembly 10 for a reactor according to an embodiment of the present invention is described in detail below.
As shown in fig. 1 and 5, the lance 300 is in an inserted state, in which case a gas (e.g., natural gas or coal gas, etc.) may be bubbled into the reactor through the nozzle assembly 10 for the reactor. As shown in fig. 1, when the lance 300 is inserted into the passage 101, external combustion gas enters the lance 300 through the combustion gas inlet 304; as shown in fig. 5, the self-destructive element 301 of the lance 300 is melted or burned to self-destruct after contacting with the melt in the reactor, and is blown into the reactor along with the combustion gas through the passage 101. It is noted that the external process air at the process air inlet 201 in the tee 200 should be shut off immediately after the lance 300 is inserted during the production of the reactor.
As shown in FIG. 2, the lance 300 is in an extracted condition, at which time process air (e.g., air or oxygen-enriched air) may be blown into the reactor through the nozzle assembly 10 for the reactor. When the process air is blown into the reactor, the spray gun 300 is not needed to be used, the control member 203 (for example, the control member 203 can be a sealing steel ball) in the tee joint 200 is in a sealing position, the control member 203 disconnects the outer port 202, and the process air is blown into the reactor through the channel 101 after passing through the process air inlet 201.
As shown in fig. 3, when the blowing of the process air or the gas into the reactor is stopped, the blocking rod 400 may be inserted into the passage 101. During production of the reactor, the external process air at the process air inlet 201 in the tee 200 should be immediately shut off when the plugging rod 400 is inserted in the channel 101.
Thus, according to the nozzle assembly 10 for a reactor of the embodiment of the present invention, different mediums, for example, process air or fuel gas, can be selectively blown directly into the reactor to supplement heat and rapidly raise the temperature of the melt in the reactor; and the service life is long, the use is flexible, and the media blown into the reactor and the use state (such as opening or closing) can be flexibly adjusted according to the process requirements in production.
According to some embodiments of the present invention, as shown in fig. 1, the outer peripheral wall of the inner end of the lance 300 protrudes outward in the radial direction of the lance 300 to form a fitting portion 302, and the fitting portion 302 abuts against the wall surface of the passage 101 in the inserted state of the lance 300, so that the melt can be prevented from entering between the passage 101 and the lance 300.
Further, as shown in fig. 1-5, an air duct 102 is disposed in the nozzle body 100, and a channel 101 is formed in the air duct 102. For example, the air duct 102 may be a wear-resistant steel duct, which is beneficial to resisting the erosion of the nozzle body 100 caused by the high-speed gas, and thus, the service life of the nozzle body 100 is prolonged.
In some embodiments of the present invention, as shown in fig. 1, the inner peripheral wall of the inner end of the air duct 102 protrudes inward in the radial direction of the air duct 102 to form a throat 103, thereby facilitating the operations of inserting the lance 300, opening the tuyere and blocking the tuyere, and particularly preventing the blocking rod 400 from being inserted into the melt or blocked insufficiently when the tuyere is blocked. Wherein, the matching part 302 is jointed with the necking 103 when the spray gun 300 is inserted.
In some embodiments of the present invention, as shown in fig. 1, the shape of the self-destructive element 301 is adapted to the shape of the throat 103, and the self-destructive element 301 is spaced apart from the throat 103 to facilitate insertion of the lance 300 and contact of the self-destructive element 301 with the melt. For example, the radial width of the self-damaging element 301 decreases gradually inward in the axial direction of the lance 300.
Further, as shown in fig. 1, the radial width of the fitting portion 302 gradually increases and then gradually decreases inward in the axial direction of the spray gun 300, so that the fitting portion 302 can smoothly abut against or separate from the throat 103.
According to some embodiments of the present invention, as shown in fig. 1, when the lance 300 is in the inserted state and the self-damaged element 301 is in the plugged state, the self-damaged element 301 protrudes inward beyond the inner end surface of the nozzle body 100, so that the self-damaged element 301 has a larger contact area with the melt, and the self-damaged element 301 is more easily softened and melted by heat.
According to some embodiments of the invention, the inner end of the lance 300 may be a heat resistant stainless steel tubing for longer life.
According to some embodiments of the present invention, a flow guide or a nozzle may be disposed inside the inner end of the spray gun 300, so as to facilitate the fluid flow and provide a better heat compensation effect.
According to some embodiments of the present invention, as shown in fig. 1, a clip 303 is sleeved on the spray gun 300, a ferrule 204 is disposed in the outer port 202, and the clip 303 is connected to the ferrule 204, so that the spray gun 300 and the tee 200 can be fixed together.
According to some embodiments of the present invention, as shown in fig. 1 and 2, a control channel 205 is provided in the tee 200 in communication with the external port 202, the control member 203 is pushed into the control channel 205 when the spray gun 300 is inserted into the tee 200, and the control member 203 is slid to the external port 202 when the spray gun 300 is pulled out of the tee 200. In this way, the control member 203 can be used to conveniently control the on/off of the external port 202. For example, the control channel 205 extends obliquely from outside to inside away from the outer port 202 so that the control member 203 can fall back to the outer port 202 under the influence of gravity.
According to some embodiments of the present invention, as shown in FIG. 1, a cooling circuit 104 is formed within the nozzle body 100 adjacent to the channel 101, the cooling circuit 104 being defined by cooling tubes disposed around the channel 101. The inner end surface of the nozzle body 100 directly contacts the high-temperature melt in the reactor, and the nozzle body 100 can be cooled by introducing cooling water into a cooling pipe, for example, the nozzle body 100 is a copper part, and the cooling pipe can be a copper pipe. Of course, the cooling circuit 104 may also extend circuitously along the axial direction of the passage 101, for example, the cooling circuit 104 may be defined by cooling slots within the nozzle body 100.
In some embodiments of the present invention, as shown in fig. 1, the inner side end surface of the nozzle body 100 may further be provided with an annular groove 105, which is beneficial for the splashed melt to adhere to the inner side end surface of the nozzle body 100 and form a stable slag crust, so that the service life of the nozzle body 100 may be prolonged, and the use safety may be ensured.
In some embodiments of the present invention, as shown in fig. 1, the outer end of the spray gun 300 includes a gas inlet 304 and a grip portion 305, the outer end of the gas inlet 304 is connected to an external flexible gas line, the inner end of the grip portion 305 is communicated with the inner end of the gas inlet 304, and the outer end of the grip portion 305 is sealed by a cover 306, thereby facilitating the operation of the spray gun 300.
The reactor 1 according to the embodiment of the second aspect of the present invention comprises: a nozzle assembly 10 and a reaction chamber 20 for a reactor according to embodiments of the first aspect of the invention. The inner end of the nozzle body 100 is inserted into the reaction chamber 20 and inwardly beyond or flush with the inner wall of the reaction chamber 20.
According to the reactor 1 provided by the embodiment of the invention, the nozzle assembly 10 for the reactor is utilized, so that the heat compensation is rapid, the service life is long, and the use is flexible.
The reactor 1 according to one embodiment of the present invention is described in detail below with reference to the accompanying drawings.
The reactor 1 in this example is a side blown furnace. A plurality of nozzle assemblies 10 for the reactor are arranged at a tuyere copper water jacket 21 on one layer of the side-blown converter, and a nozzle body 100 and the tuyere copper water jacket 21 on one layer of the side-blown converter are arranged together and are arranged together with a tee joint 200 through a connecting piece 11. The inner end surface of the nozzle body 100 contacts the high-temperature melt in the side-blown furnace, and oxygen-enriched air is blown into the side-blown furnace through the tee joint 200 or natural gas is blown into the side-blown furnace through the spray gun 300. After the nozzle assembly 10 for the reactor is installed on the side-blown converter, before the side-blown converter is heated, cooling circulating water needs to be introduced into the cooling pipe, and the flow rate and the pressure of the cooling circulating water meet the process requirements.
During normal production of the side-blown converter, oxygen-enriched air and natural gas are introduced into and blown into the side-blown converter through the tee 200 and the gas lance 300 in the nozzle assembly 10 for the reactor at different positions in the side-blown converter according to process requirements.
When oxygen-enriched air or natural gas does not need to be blown into the side-blown converter, the nozzle assembly 10 for the reactor is blocked by the blocking rod 400; when the nozzle assembly 10 for the reactor is blowing natural gas into the side-blown furnace, it is necessary to insert the lance 300 while turning off the oxygen-enriched air; when the nozzle assembly 10 for a reactor is used to blow oxygen-enriched air into a side-blown furnace, it is not necessary to insert the lance 300 and the plugging rod 400.
When it is necessary to replace or stop the nozzle assembly 10 for a reactor being used due to process requirements, it is necessary to rapidly insert the plugging rod 400 into the passage 101 before shutting off the oxygen-enriched air in the nozzle assembly 10 for a reactor, and to shut off the oxygen-enriched air in the nozzle assembly 10 for a reactor after the operation of the plugging rod 400 is completed.
