That is, the blowing chamber 200 is provided with the outlet 204, the first inlet 201, the second inlet 202, and the control port 203 from inside to outside. The blowing chamber 200 is provided therein with a control member 205 for opening and closing the control port 203, and for example, the control member 205 may be a steel ball, and the outer end surface of the blowing chamber 200 is sealed by the steel ball when the blocking rod 300 is not inserted.
Here, the outer end of the body 100 refers to an end of the body 100 located outside the reactor, and the inner end of the body 100 refers to an end of the body 100 located inside the reactor; the outer end of the blowing chamber 200 refers to the end of the blowing chamber 200 facing away from the body 100, and the inner end of the blowing chamber 200 refers to the end of the blowing chamber 200 facing toward the body 100.
Whereby the crushed electronic waste enters the blowing chamber 200 through the first inlet 201 together with a pneumatic conveying gas (e.g. normal air); a pneumatic conveying gas (e.g., normal air) may also be injected separately into the first inlet 201 to purge electronic waste at the interface of the first inlet 201. The gas pressure in the second inlet 202 is higher than the gas pressure in the first inlet 201 in order to prevent electronic waste from entering the outside of the injection chamber 200 from the first inlet 201 and causing a blockage at the cooperation of the control opening 203 and the control member 205.
According to the blowing device 10 for the reactor, disclosed by the embodiment of the invention, the crushed electronic waste can be directly blown into a molten pool in the reactor for reaction, so that the electronic waste can be fully reacted in the reactor, and meanwhile, the reaction heat of the electronic waste in the reactor can be used for increasing the melt temperature in the reactor, so that the input amount of fuel in raw materials of the reactor can be reduced, and the energy conservation and the environmental protection are facilitated; in addition, the blowing device 10 for the reactor is flexible to use, and the number, the positions and the use states of the blowing devices 10 for the reactor can be flexibly adjusted according to process requirements in production.
It is understood that the number of the first inlet 201 and the second inlet 202 may be plural, and those skilled in the art may make corresponding adjustments according to actual process requirements.
According to some embodiments of the present invention, as shown in fig. 1, the blowing chamber 200 extends in a horizontal direction, and the first inlet 201 and the second inlet 202 extend obliquely upward from the peripheral wall of the blowing chamber 200, respectively, thereby facilitating installation and gas flow.
According to some embodiments of the present invention, as shown in fig. 1, a portion of the inner peripheral wall of the blast chamber 200 extends inward to form a first constriction 206, the first constriction 206 being located between the first inlet 201 and the second inlet 202, thereby facilitating the prevention of crushed electronic waste from entering the outside of the blast chamber 200 and causing a blockage at the control opening 203.
In some embodiments of the present invention, as shown in fig. 1, a flare 207 is disposed on a side of the first constriction 206 facing the first inlet 201, and the flow area of the flare 207 is larger than that of the first constriction 206, so as to facilitate depressurization of the gas in the second inlet 202 before mixing with the fluid from the first inlet 201, and avoid difficulty in entering the blowing chamber 200 by the electronic waste in the first inlet 201.
Further, as shown in fig. 1, the inner end of the first constriction 206 gradually extends obliquely outward in the radial direction of the blowing chamber 200 to the inner peripheral wall of the blowing chamber 200 to form a flare 207, so that the structure is relatively simple. It will be appreciated that the flare 207 is located between the first inlet 201 and the first constriction 206.
According to some embodiments of the present invention, as shown in fig. 1, a clamping groove 208 is formed at the control port 203, and the outer side of the clamping groove 208 is connected to a clamping piece 209 to seal the outer end surface of the blowing chamber 200.

When the blocking rod 300 is inserted into the blowing chamber 200, the control member 205 is pushed into the control passage 210, and when the blocking rod 300 is pulled out of the blowing chamber 200, the control member 205 falls back to the control port 203 under the action of gravity. In this way, the control piece 205 can be used to conveniently control the on-off of the control port 203.
According to some embodiments of the present invention, an air duct 102 is provided in the 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 tube that facilitates resisting the flushing of the body 100 with high velocity air, extending the useful life of the body 100.
Further, as shown in fig. 2, 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 the second constriction 103, so that the air opening and air blocking operation are facilitated, and particularly when the air opening is blocked, the blocking rod 300 can be prevented from being inserted into the melt or blocked in place. When the blocking rod 300 is inserted into the channel 101, the inner end of the blocking rod 300 protrudes radially outward to engage the second constriction 103.
According to some embodiments of the present invention, as shown in fig. 1, a cooling circuit 104 disposed adjacent to the passage 101 is formed in the body 100, the cooling circuit 104 being defined by cooling tubes disposed around the passage 101. The inner end surface of the body 100 directly contacts the high temperature melt in the reactor, and the body 100 can be cooled by introducing cooling water into a cooling pipe, for example, the body 100 is a copper piece, and the cooling pipe can be a copper pipe. Of course, the cooling circuit 104 may also extend circuitously in the axial direction of the channel 101, for example, the cooling circuit 104 may be defined by cooling slots in the body 100.
In some embodiments of the present invention, as shown in fig. 1, the inner end surface of the body 100 may further be provided with an annular groove 105, which is beneficial for the splashed melt to adhere to the inner end surface of the body 100 and form a stable slag skin, so that the service life of the body 100 may be prolonged, and the use safety is ensured.
The reactor 1 according to the embodiment of the second aspect of the present invention comprises: comprising the following steps: a blowing device 10 and a reaction chamber 20 for a reactor according to an embodiment of the first aspect of the present invention. The inner end of the 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 of the embodiment of the invention, the blowing device 10 for the reactor can be utilized to directly blow the crushed electronic waste into a molten pool in the reactor 1 for reaction, so that the electronic waste can fully react in the reactor 1, and meanwhile, the reaction heat of the electronic waste in the reactor 1 can be used for increasing the temperature of the melt in the reactor 1, thereby reducing the input amount of fuel in raw materials of the reactor 1, being beneficial to saving energy and protecting environment; in addition, the blowing device 10 for the reactor is flexible to use, and the number, the positions and the use states of the blowing devices 10 for the reactor can be flexibly adjusted according to process requirements in production.
The reactor 1 according to an embodiment of the present invention is described in detail below with reference to the accompanying drawings.
In this example, the reactor 1 is a side-blown furnace. A plurality of blowing devices 10 for reactors are disposed at one layer of tuyere copper water jackets 21 of the side-blown furnace, and the body 100 is installed together with the one layer of tuyere copper water jackets 21 and with the blowing chamber 200 through the connection members 11. The inner end surface of the body 100 contacts the high temperature melt in the side-blowing furnace and blows the crushed electronic scrap into the side-blowing furnace through the blowing chamber 200. After the injection device 10 for the reactor is installed on the side-blown furnace, cooling circulating water needs to be introduced into the cooling pipe before the temperature of the side-blown furnace rises, and the flow and the pressure of the cooling circulating water meet the process requirements.
During normal production of the side-blowing furnace, crushed electronic waste and pneumatic conveying gas are blown into the side-blowing furnace through a first inlet 201 on the blowing chamber 200, gas in a second inlet 202 is simultaneously sprayed into the furnace, and the gas pressure in the second inlet 202 is higher than that in the first inlet 201.
When the blowing device 10 for a reactor being used needs to be replaced or stopped due to process requirements, the first inlet 201 needs to be closed, then the purge wind in the first inlet 201 is opened, then the first inlet 201 is closed, then the blocking rod 300 is inserted into the blowing device 10 for a reactor, and after the blocking rod 300 is operated, the second inlet 202 is closed; in case of emergency, when the first inlet 201 is closed, the blocking rod 300 is rapidly inserted into the blowing device 10 for a reactor, and the second inlet 202 is closed.
