[0026] In industrial production, liquid-solid reactions are mostly intermittent production with liquid-solid reactors as the main body, and solid feeding is mostly done manually. Although the manual feeding method can achieve intermittent addition of solid raw materials, it has problems such as long reaction time and low level of automation.

[0027] In view of this, the present application provides a liquid-solid reaction gas production system and a liquid-solid reaction gas production method, by automatically switching multiple second feed valves, the solid-phase raw materials in the weighing bin are transported in batches to multiple transition bins, and by automatically switching multiple discharge valves, the solid-phase raw materials in the multiple transition bins are transported in batches to the liquid-solid reactor, thereby realizing continuous and automated feeding of the solid phase of the liquid-solid reactor. Compared with the manual intermittent feeding method, the airtightness, accuracy and automation level of the solid-phase feeding process are improved, thereby improving the production efficiency and automation level of the liquid-solid reaction gas production system.

[0028] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0029] like Figure 1 As shown, the present application provides a liquid-solid reaction gas production system, which includes a solid phase feeding system 1, a liquid-solid reactor 2, a liquid phase feeding system 4 and a gas phase storage tank 5:

[0030] The solid phase feeding system 1 comprises a solid phase storage bin 101, a continuous conveyor 102, a weighing bin 105, a first feeding valve 103 corresponding to the weighing bin 105, a plurality of transition bins (108, 111), a plurality of second feeding valves (106, 109) corresponding one-to-one to the plurality of transition bins (108, 111), and a plurality of discharge valves (112, 113) corresponding one-to-one to the plurality of transition bins (108, 111).

[0031] like Figure 1 As shown, it includes two transition bins (108, 111) and two second feed valves (106, 109) corresponding one-to-one to the two transition bins (108, 111) and two discharge valves (112, 113) corresponding one-to-one to the two transition bins (108, 111), wherein the transition bin 108 corresponds to the second feed valve 106 and the discharge valve 113, and the transition bin 111 corresponds to the second feed valve 109 and the discharge valve 112.

[0032] It should be noted that, in practical applications, the actual number of multiple transition bins can be set as needed and is not limited here.

[0033] The solid phase storage bin 101 is used to store solid phase raw materials, that is, the solid phase raw materials can be stored in the solid phase storage bin 101 .

[0034] The feed port of the continuous conveyor 102 is connected to the discharge port of the solid phase storage silo 101 , and the discharge port is connected to the feed port of the weighing bin 105 through the first feed valve 103 . The continuous conveyor 102 is used to transport the solid phase raw materials in the solid phase storage silo 101 to the weighing bin 105 .

[0035] The discharge port of the weighing bin 105 is respectively connected to the feed ports of the multiple transition bins (108, 111) through the multiple second feed valves (106, 109), and is used to weigh the solid-phase raw materials and transport the weighed solid-phase raw materials in batches to the multiple transition bins (108, 111) through the automatic switching of the multiple second feed valves (106, 109).

[0036] Specifically, the weighing bin 105 can complete the quantitative control of the solid phase raw material, such as Figure 1 As shown, the weighing bin 105 is connected to the transition bin 108 through the second feed valve 106, and the weighing bin 105 is connected to the transition bin 111 through the second feed valve 109. After the weighing bin 105 completes the weighing of the solid-phase raw material, the weighed solid-phase raw material can be delivered to the transition bin 108 through the second feed valve 106 or delivered to the transition bin 111 through the second feed valve 109, thereby realizing batch delivery of the weighing bin 105 and multiple transition bins (108, 111) through automatic switching of multiple second feed valves (106, 109).

[0037] The multiple transition bins (108, 111) are respectively connected to the solid phase feed port of the liquid-solid reactor 2 through the multiple discharge valves (112, 113), and the solid phase raw materials in the multiple transition bins (108, 111) are transported to the liquid-solid reactor 2 in batches through the automatic switching of the multiple discharge valves (112, 113).

[0038] Specifically, Figure 1 As shown, the transition bin 108 is connected to the solid phase feed port of the liquid-solid reactor 2 through the discharge valve 113, and the transition bin 111 is connected to the solid phase feed port of the liquid-solid reactor 2 through the discharge valve 112. The transition bin 108 can transport solid phase raw materials to the liquid-solid reactor 2 through the discharge valve 113, or the transition bin 111 can transport solid phase raw materials to the liquid-solid reactor 2 through the discharge valve 112.

[0039] The weighed solid-phase raw materials are transported in batches to the multiple transition bins (108, 111) by automatic switching of the multiple second feed valves (106, 109), and the solid-phase raw materials in the multiple transition bins (108, 111) are transported in batches to the liquid-solid reactor 2 by automatic switching of the multiple discharge valves (112, 113). Unlike a single transition bin that can only realize intermittent feeding, the multiple transition bins (108, 111) can be alternately fed to the liquid-solid reactor 2 by mutual switching between the multiple second feed valves (106, 109) and the multiple discharge valves (112, 113), thereby realizing continuous and automated solid-phase feeding.

[0040] The liquid-solid reactor 2 is used for generating corresponding gas by liquid-solid reaction of the solid raw material delivered by the solid-phase feeding system 1 and the liquid raw material delivered by the liquid-phase feeding system 4 .

[0041] The liquid phase feeding system 4 is connected to the liquid phase feeding port of the liquid-solid reactor 2 and is used to realize the liquid phase continuous feeding of the liquid-solid reactor 2 .

[0042] The gas phase storage tank 5 is connected to the gas phase discharge port of the liquid-solid reactor 2 and is used to store the gas generated by the liquid-solid reactor 2 .

[0043] In a possible implementation, in order to ensure the purity of the solid-phase feed of the solid-phase feeding system 1 to the liquid-solid reactor 2, the solid-phase feeding system 1 also includes a protective gas source 114, a recovery tank 118, a plurality of intake valves (115, 116, 117) corresponding one-to-one to the weighing bin 105 and the plurality of transition bins (108, 111), and a plurality of exhaust valves (104, 107, 110) corresponding one-to-one to the weighing bin 105 and the plurality of transition bins (108, 111).

[0044] The protective gas source 114 is connected to the weighing bin 105 and the multiple transition bins (108, 111) through multiple inlet valves (115, 116, 117) respectively, and is used to transport protective gas to the weighing bin 105 and the multiple transition bins (108, 111) to replace the substances in the bins.

[0045] like Figure 1 As shown, the protective gas source 114 is correspondingly connected to the weighing bin 105 through the air intake valve 115, correspondingly connected to the transition bin 108 through the air intake valve 117, and correspondingly connected to the transition bin 111 through the air intake valve 116. The protective gas source 114 can transport protective gas to the weighing bin 105 and multiple transition bins (108, 111) to replace the moisture, air and product gas in the bins.

[0046] The recovery tank 118 is respectively connected to the weighing bin 105 and the multiple transition bins (108, 111) through multiple exhaust valves (104, 107, 110) and is used to recover the substances in the weighing bin 105 and the multiple transition bins (108, 111).

[0047] like Figure 1 As shown, the recovery tank 118 is correspondingly connected to the weighing bin 105 through the exhaust valve 104, correspondingly connected to the transition bin 108 through the exhaust valve 107, and correspondingly connected to the transition bin 111 through the exhaust valve 110. The recovery tank 118 can recover moisture, air and product gas in the weighing bin 105 and multiple transition bins (108, 111).

[0048] In a possible implementation, the main body of the liquid-solid reactor 2 is a conical reaction chamber 201 , and the conical angle of the conical reaction chamber 201 may range from 15° to 45°.

[0049] A motor 210 is disposed on the top of the conical reaction chamber 201 , and the motor speed of the motor 210 may be 1 rpm to 100 rpm.

[0050] A single cantilever stirrer 202 connected to a motor 210 is arranged inside the conical reaction chamber 201. The stirring shaft of the single cantilever stirrer 202 is arranged parallel to the conical hypotenuse of the conical reaction chamber 201. A spiral ribbon blade is arranged on the stirring shaft of the single cantilever stirrer 202. The motor 210 is used to drive the single cantilever stirrer 202 to rotate and drive the single cantilever stirrer 202 to revolve around the axis of the conical reaction chamber 201.

[0051] Compared with the method of stirring and mixing in the center of the liquid-solid reactor 2 in the related art, the method of this embodiment can realize the radial flipping and axial turning of the material, that is, the radial mixing of the material is realized while the axial mixing of the material is also realized, which is beneficial to the uniform mixing of the liquid and solid phases, improves the mass transfer reaction efficiency, and thus helps to shorten the reaction time.

[0052] At the same time, the structural coordination between the conical reaction chamber 201 and the single cantilever stirrer 202 is conducive to reducing the resistance when the motor 210 is started, which is conducive to saving energy consumption.

[0053] In one possible implementation, a hemispherical valve 204 is further provided at the bottom of the conical reaction chamber 201, and the hemispherical valve 204 is used to realize the automatic discharge of the solid residue in the conical reaction chamber 201, that is, the hemispherical valve 204 located at the bottom of the conical reaction chamber 201 can discharge the solid residue, so that the discharge process does not require manual participation, further improving the automation level of the liquid-solid reaction gas production system.

[0054] In a possible implementation, considering that there is a dead zone at the bottom of the conical reaction chamber 201 that cannot be stirred by the single cantilever agitator 202, a liquid replenishment port 203 may be further provided at the bottom side end of the conical reaction chamber 201 between the bottom of the single cantilever agitator 202 and the hemispherical valve 204. The liquid replenishment port 203 is used to replenish liquid-phase raw materials during liquid-solid reaction so as to perform liquid-solid reaction with the solid-phase raw materials at the bottom of the conical reaction chamber 201. The liquid-phase raw materials replenished from the liquid replenishment port 203 can react with a small portion of solid-phase materials at the bottom of the conical reaction chamber 201, thereby preventing the dead zone at the bottom of the conical reaction chamber 201 during the liquid-solid reaction.

[0055] In a possible implementation, the liquid replenishing port 203 is also used to inject a solvent or a protective gas after the liquid-solid reaction in the conical reaction chamber 201 stops, so as to assist the hemispherical valve 204 in removing solid residues.

[0056] In one possible implementation, a heat exchange shell 206 is further provided on the outer surface of the liquid-solid reactor 2. The heat exchange shell can be in the form of a heat exchange jacket or a coil. A heat exchange inlet 205 and a heat exchange outlet 209 are provided on the heat exchange shell 206. The heat exchange inlet 205 and the heat exchange outlet 209 are respectively connected to the external heat exchange medium delivery pipeline. The heat exchange shell 206 is used to ensure the internal reaction temperature of the liquid-solid reactor 2 by transferring the heat generated by the liquid-solid reaction.

[0057] In one possible implementation, the liquid-solid reaction gas production system also includes a control system 3, and a temperature sensor 207 and a pressure sensor 208 are also provided inside the liquid-solid reactor 2. The temperature sensor 207 is used to obtain the internal reaction temperature of the liquid-solid reactor 2 in real time, and the pressure sensor 208 is used to obtain the internal pressure change of the liquid-solid reactor 2 in real time. The liquid-phase feeding system 4 is provided with a liquid-phase feeding valve 402, and the liquid-phase feeding valve 402 is used to control the liquid-phase feeding system 4 to feed the liquid-solid reactor 2.

[0058] The control system 3 is connected to the temperature sensor 207, the pressure sensor 208, the first feed valve 103, the liquid-phase feed valve 402, the heat exchange inlet 205 and the heat exchange outlet 206 respectively. The control system 3 is used to adjust the feed amount of the solid-phase raw material, the feed amount of the liquid-phase raw material and the circulation amount of the heat exchange shell 206 by changing the internal reaction temperature and internal pressure of the liquid-solid reactor 2, thereby ensuring that the liquid-solid reaction in the liquid-solid reactor 2 proceeds stably. At the same time, when extreme conditions such as reaction hypothermia occur, the input of the reaction raw materials can be cut off in time, thereby ensuring the safety of the reaction.

[0059] In one possible implementation, the liquid phase feeding system 4 includes a liquid phase storage tank 401 and a continuous conveying and metering device 403, the discharge port of the liquid phase storage tank 401 is connected to the feed port of the continuous conveying and metering device 403, and the discharge port of the continuous conveying and metering device 403 is connected to the liquid phase feed port of the liquid-solid reactor 2. The continuous conveying and metering device 403 can complete the continuous and automated liquid phase feeding from the liquid phase storage tank 401 to the liquid-solid reactor 2.

[0060] In one possible implementation, a gas-solid separator 211 is provided on the gas phase discharge port of the liquid-solid reactor 2, and the discharge port of the gas-solid separator 211 is connected to the gas phase storage tank 5 through a gas phase discharge valve 212. The gas-solid separator 211 is used to prevent the gas generated by the liquid-solid reactor 2 from carrying away solid phase particles when being discharged, thereby ensuring the purity of the gas in the gas phase storage tank 5.

[0061] The following method examples are used to illustrate the liquid-solid reaction gas production method based on the above-mentioned liquid-solid reaction gas production system provided by the present application. Figure 2 As shown, Figure 2 A schematic flow chart of a liquid-solid reaction gas production method provided in an embodiment of the present application, the method comprising:

For the solid phase feeding system 1, open the first feed valve 103 so that the continuous conveyor 102 can transport the solid phase raw material in the solid phase storage bin 101 to the weighing bin 105, and automatically switch multiple second feed valves (106, 109) and multiple discharge valves (112, 113) to realize continuous solid phase feeding of the liquid-solid reactor 2.

[0063] In the process of multiple feedings, the kth feeding is taken as an example for explanation, based on the i-th second feeding valve 106 and the j-th second feeding valve 109 among the multiple second feeding valves (106, 109) as an example for explanation, the i-th second feeding valve 106 is opened so that the weighing bin 105 can convey the solid-phase raw material to the i-th transition bin 108 among the multiple transition bins (108, 111), and the loading amount of the i-th transition bin 108 can be determined by the conveying amount and conveying time of the continuous conveyor 102 and the weight change of the weighing bin 105. After the i-th transition bin 108 is loaded with the solid-phase raw material, the i-th second feeding valve 106 is closed and the j-th second feeding valve 109 is opened so that the weighing bin 105 can continuously convey the solid-phase raw material to the j-th transition bin 111 among the multiple transition bins (108, 111), and the i-th discharge valve 113 among the multiple discharge valves (112, 113) is opened so that The i-th transition bin 108 transports the solid-phase raw material to the liquid-solid reactor 2. After the i-th transition bin 108 completes transporting the solid-phase raw material to the liquid-solid reactor 2, the j-th discharge valve 112 among the multiple discharge valves (112, 113) is opened so that the j-th transition bin 111 transports the solid-phase raw material to the liquid-solid reactor 2. After the j-th transition bin 111 completes transporting the solid-phase raw material to the liquid-solid reactor 2, the k+1-th feeding can be performed, that is, in each feeding, the solid-phase raw material can be alternately transported to the liquid-solid reactor 2 through two different transition bins, so that continuous automated solid-phase feeding of the liquid-solid reactor 2 can be achieved through multiple transition bins. The i-th second feed valve 106 corresponds to the i-th transition bin 108 and the i-th discharge valve 113, and the j-th second feed valve 109 corresponds to the j-th transition bin 111 and the j-th discharge valve 112. k is an integer, i is a positive integer, j is a positive integer, and i≠j.
