Description

Technical Field

[0001] The present invention relates to the technical field of polycarbon gas decomposition and carbon and slag removal, and specifically relates to a high-residence reactor. Background Art

[0002] The high-pressure reactor (magnetic high-pressure reactor) is a typical innovation in the application of magnetic drive devices to reaction equipment. It fundamentally solves the problem of shaft seal leakage that could not be overcome by previous packing seals and mechanical seals, without any leakage and pollution. It is the most ideal device for carrying out chemical reactions under high temperature and high pressure in China, especially for carrying out chemical reactions with flammable, explosive, and toxic media, which more prominently shows its superiority.

[0003] Currently, most of the developed similar devices are ordinary high-pressure reaction furnace devices, which are difficult to be applied to reaction processes involving simultaneous participation of high-temperature (above one thousand degrees Celsius) gases and solids. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-residence reactor to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A high-residence reactor, which includes:

[0006] A hollow reaction unit, with an inlet provided on the upper left side of the reaction unit and an outlet provided on the lower right side of the reaction unit;

[0007] Inside the reaction unit, channels one, two, three, and four are formed from left to right through partitions. Channels one and two are both U-shaped double channels, and a flow port is formed between the lower part of the partition of the double channel and the inner wall of the reaction unit;

[0008] A raw material gas inlet provided at the inlet, and the raw material gas inlet extends downward to communicate with the inlet and channel one;

[0009] A blocking throat provided at the upper right end of the reaction unit, corresponding to the position of channel four. A floating arm is provided inside the blocking throat, and the floating arm can move inside the blocking throat and extend into channel four. A low-pressure chamber is provided on the upper part of the right side wall of the reaction unit, and an air outlet is provided on the upper side of the low-pressure chamber;

[0010] The upper right end of channel one is connected to the upper left end of channel two, the upper part of channel three is connected to the upper right end of channel two, the upper end of channel four is connected to the upper end of channel three, the upper left side of the low-pressure chamber is connected to channel four, and the outlet is connected to channel four.

[0011] Further, an arc-shaped guiding vane is provided at the upper end inside channel three.

[0012] Furthermore, two driving motors are arranged at the upper part of the reaction unit. The two driving motors respectively correspond to the right channels of Channel 1 and Channel 2. Propellers are rotatably installed in the right channels of Channel 1 and Channel 2, and the output shafts of the driving motors are connected to the corresponding propellers.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] It is completed by creating multiple channels, which increases the heat rate transfer and surface area interaction, optimizes the volume of the reaction unit, and improves the decomposition yield because the mixing speed is faster in each segmented channel, the residence time is extended, and the bubble / melt interaction is longer.

[0015] By using multiple propellers, the large bubbles in the reaction channel are crushed into very fine bubbles, which increases the decomposition rate and surface interaction with the high-temperature melt, and at the same time reduces the number of macropore densities in the melt.

[0016] The propeller can also act as a slurry pump by accelerating the flow of the subsequent material, thereby generating a pumping action and controlling the flow rate in the reaction environment. Therefore, the flow rate of the melt in the flow channel can be controlled by controlling the rotation speed of the propeller. The problem of the formation of scum (inclusions) and carbon particles is also solved by removing the scum. In the final stage, the scum and carbon particles are overflowed into a separate low-pressure chamber through a floating arm. In addition, the gas escapes into the low-pressure chamber and leaves from the top. This geometrically directed gas flow pushes the scum and carbon to the low-pressure chamber, thus facilitating the removal process. Then the remaining melt is discharged in a controlled manner and then circulated to the reaction unit by a pump. The structure of the present invention is compact, and it solves various problems faced in various applications such as the chemical industry, casting, and metal industry.

[0023] A hollow reaction unit 1, an inlet 2 is provided on the upper left side of the reaction unit 1, and an outlet 3 is provided on the lower right side of the reaction unit 1;

[0024] Inside the reaction unit 1, a channel one 4, a channel two 5, a channel three 6 and a channel four 7 are formed from left to right by a partition. The channel one 4 and the channel two 5 are both U-shaped double channels, and a flow port 8 is formed between the lower part of the partition of the double channel and the inner wall of the reaction unit 1;

[0025] A raw material gas inlet 9 provided at the inlet 2, and the raw material gas inlet 9 extends downward and communicates with the inlet 2 and the channel one 4;

[0026] A blocking throat 13 is provided at the upper right end of the reaction unit 1. The blocking throat 13 corresponds to the position of the channel four 7. A floating arm 14 is provided inside the blocking throat 13. The floating arm 14 moves inside the blocking throat 13 and can extend into the channel four 7. An upper part of the right side wall of the reaction unit 1 is provided with a low-pressure chamber 15, and an air outlet 16 is provided on the upper side of the low-pressure chamber 15;

[0027] The upper right end of the channel one 4 is communicated with the upper left end of the channel two 5, the upper part of the channel three 6 is communicated with the upper right end of the channel two 5, the upper ends of the channel four 7 and the channel three 6 are communicated with each other, the upper left side of the low-pressure chamber 15 is communicated with the channel four 7, and the outlet 3 is communicated with the channel four 7.

[0028] Preferably, an arc-shaped guide vane 12 is provided at the upper end inside the channel three 6.

[0029] Preferably, two driving motors 10 are provided on the upper part of the reaction unit 1. The two driving motors 10 respectively correspond to the right channels of the channel one 4 and the channel two 5. Propellers 11 are rotatably installed in the right channels of the channel one 4 and the channel two 5, and the output shafts of the driving motors 10 are connected to the corresponding propellers 11.

[0030] Working principle: The high-temperature melt from the heating unit ( Figure 1 not shown) enters the reaction unit 1 from the inlet 2.

[0031] The reaction unit 1 is divided into multiple channels, namely channel one 4, channel two 5, channel three 6, and channel four 7. As Figure 1 shown, channel one 4, channel two 5, channel three 6, and channel four 7 are arranged from left to right, and the high-temperature melt flows in an S shape in channel one 4, channel two 5, and channel three 6. Finally, at channel four 7, the dross and carbon are separated from the high-temperature melt.

[0032] Each channel segment is separated by a partition (as Figure 1 shown, the partition is the side wall of the channel).

[0033] Channel one 4 and channel two 5 have a double channel. At the right channel part of channel one 4 and channel two 5, a mating connection structure for the drive motor 10 and the propeller 11 is provided, and the drive motor 10 drives the propeller 11 to rotate.

[0034] When the high-temperature melt completely occupies channel one 4, channel two 5, channel three 6, and channel four 7, the raw material gas enters from the raw material gas inlet 9 in the form of bubbles, flows in the first channel segment of channel one 4, leaves from the flow port 8, and enters the second channel segment of channel one 4.

[0035] 1 Reaction unit, 2 Inlet, 3 Outlet, 4 Channel one, 5 Channel two, 6 Channel three, 7 Channel four, 8 Flow port, 9 Raw material gas inlet, 10 Drive motor, 11 Propeller, 12 Guide vane, 13 Blocked throat, 14 Float arm, 15 Low-pressure chamber, 16 Gas outlet.

[0036] The bubbles and the formed inclusions are fully mixed, the bubbles are crushed into finer bubbles, and are pumped together by the propeller 11 in channel one 4 to the first segment of channel two 5. Since both channel one 4 and channel two 5 have the drive motor 10 and the connected propeller 11 in series, this enables the high-temperature melt to be continuously pumped to channel three 6. The flow of the high-temperature melt is geometrically guided by the guide vane 12 to channel three 6. When channel three 6 is filled, it slowly overflows to the narrow channel four 7. Channel four 7 is laterally connected to the low-pressure chamber 15, where all the dross and carbon are collected.

[0037] The feed bubbles trying to escape from the high-temperature melt will be geometrically guided by the guide vane 12 in channel three 6. This gas-guided air flow will push the dross and carbon to the low-pressure chamber 15 and then escape from the gas outlet 16.

[0038] Above the fourth channel 7, a choke throat 13 is also laid, and a floating arm 14 is arranged inside the choke throat 13. When scum and carbon accumulate in the fourth channel 7, the floating arm 14 can be pushed downward so that the scum and carbon overflow into the low-pressure chamber 15. Then, the high-temperature melt is discharged through the outlet 3 to the main heating unit (not shown) in a controlled manner, and then circulates back to the inlet 2 of the reaction unit 1 continuously.

For a person skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
