[0043] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0044] In the prior art, the slurry is discharged to the buffer tank of the slurry process. The slurry is left to settle in the buffer tank, and the metal chlorides and polychlorosilanes with higher density settle to the bottom of the tank, and then discharged into the slag discharge tank for storage. The slurry in the slag discharge tank is then sent to the dryer for heating and drying. The chlorosilanes and polychlorosilanes in the slurry are converted into gas phase in the dryer, and the metal chlorides are continuously concentrated in the dryer. After drying for a certain period of time, the metal chlorides are discharged into the hydrolysis tank for hydrolysis.

[0045] The metal chlorides and the small amount of residual chlorosilane in the slurry release a lot of heat when they meet water, generating water vapor. The water vapor will pass through the hydrolysis tank and enter the delivery pipeline. The water vapor will react with the metal chlorides or chlorosilanes remaining in the delivery pipeline to generate silicon dioxide. The silicon dioxide produced by the reaction will adhere to the inner wall of the delivery pipeline, causing the inner diameter of the delivery pipeline to become smaller or even blocked. As a result, the delivery efficiency of the delivery pipeline is low, and even maintenance and replacement are required.

[0046] In the hydrolysis device provided in the embodiment of the present application, the containing chamber is used to contain the metal chloride and the residual small amount of chlorosilane in the slurry. The first delivery pipe is used to be connected to an external dryer or a chlorosilane collection tank. The second delivery pipe is used to be connected to an external gas source, and the gas in the gas source can pass through the second delivery pipe, be guided to the nozzle, and after passing through the nozzle, be sprayed into the containing chamber toward the side close to the first delivery pipe, thereby reducing the flow of water vapor in the containing chamber toward the first delivery pipe, so as to reduce the occurrence of water vapor reacting with the metal chloride or chlorosilane remaining in the first delivery pipe to generate silicon dioxide, or can reduce the occurrence of water vapor entering the chlorosilane collection tank after passing through the first delivery pipe.

[0047] Therefore, the embodiments of the present application can solve the problem of low delivery efficiency of the delivery pipeline, or even the need for repair and replacement.

[0048] like Figure 1 and Figure 2As shown, the embodiment of the present application provides a hydrolysis device, including: a tank body 100, at least one first delivery pipe 200, at least one second delivery pipe 300 and at least one nozzle 400. The tank body 100 has a receiving chamber 101 and at least one opening 102 connected to the receiving chamber 101; a portion of the first delivery pipe 200 is provided with the opening 102 and is connected to the receiving chamber 101; a portion of the second delivery pipe 300 is provided with the opening 102 and is connected to the receiving chamber 101, and the second delivery pipe 300 is used to connect to an external gas source; the nozzle 400 is provided in the receiving chamber 101, one end of the nozzle 400 is connected to the second delivery pipe 300, and the other end of the nozzle 400 faces the side close to the first delivery pipe 200.

[0049] It should be noted that the first delivery pipe 200 provided in the embodiment of the present application has a variety of different setting functions. The setting functions of the first delivery pipe 200 are illustrated in turn below.

[0050] In a feasible implementation manner, one end of the first conveying pipe 200 is communicated with the outlet of the dryer, and the other end of the first conveying pipe 200 is communicated with the opening 102 on the tank body 100 .

[0051] It can be understood that the first conveying pipe 200 is used to convey the slurry in the dryer to the tank body 100. In this case, the opening 102 on the tank body 100 is a feed port for the slurry.

[0052] In another feasible implementation, one end of the first delivery pipe 200 is communicated with the inlet of the chlorosilane collecting tank, and the other end of the first delivery pipe 200 is communicated with the opening 102 on the tank body 100 .

[0053] It is understandable that the first delivery pipe 200 is used to deliver the chlorosilane in the tank body 100 to the chlorosilane collection tank. In this case, the opening 102 on the tank body 100 is the discharge port of the chlorosilane.

[0054] It is understandable that there is no limitation on the setting function of the first delivery pipe 200, and it can be selected according to actual use requirements.

[0055] It should be noted that the gas source is used to store gas, and there are many different ways to set the gas. The following examples will illustrate the ways to set the gas in turn.

[0056] In a feasible implementation manner, the gas is nitrogen, the gas source is a nitrogen gas tank, and the output end of the nitrogen gas tank is connected to an end of the second delivery pipe 300 away from the nozzle 400.

[0057] It is understandable that the nitrogen in the nitrogen tank can be guided to the nozzle 400 after passing through the second delivery pipe 300, and then delivered to the receiving chamber 101 through the nozzle 400. The provision of nitrogen can block the water vapor in the receiving chamber 101, so as to reduce the occurrence of the water vapor in the receiving chamber 101 entering the first delivery pipe 200, so as to extend the service life of the first delivery pipe 200.

[0058] In another feasible implementation, the gas is helium, the gas source is a helium gas tank, and the output end of the helium gas tank is connected to an end of the second delivery pipe 300 away from the nozzle 400 .

[0059] It is understandable that the helium in the helium tank can be guided to the nozzle 400 after passing through the second delivery pipe 300, and then delivered to the receiving chamber 101 through the nozzle 400. The provision of helium can block the water vapor in the receiving chamber 101, so as to reduce the occurrence of the water vapor in the receiving chamber 101 entering the first delivery pipe 200, so as to extend the service life of the first delivery pipe 200.

[0060] It is understandable that there is no restriction on the specific setting method of the gas, and it can be selected according to actual use requirements, as long as it is ensured that the gas does not chemically react with the slurry in the tank body 100.

[0061] It should be noted that the internal pressure of the tank body 100 is lower than the pressure of the gas, so that the gas toward the accommodating chamber 101 can block the water vapor in the accommodating chamber 101. The gas pressure has many different settings, and the following examples illustrate the settings of the gas pressure one by one.

[0062] In a feasible implementation manner, the internal pressure of the tank body 100 is lower than the spray pressure of the spray head 400 .

[0063] It can be understood that the internal pressure of the tank body 100 is lower than the spray pressure of the nozzle 400, so that the pressure of the gas sprayed into the containing chamber 101 through the nozzle 400 can be lower than the internal pressure of the containing chamber 101, so that the gas toward the containing chamber 101 can block the water vapor in the containing chamber 101. In this case, the nozzle 400 can be a high-pressure nozzle 400.

[0064] In another feasible implementation manner, the internal pressure of the tank body 100 is lower than the internal pressure of the second delivery pipe 300 .

[0065] It can be understood that the internal pressure of the tank body 100 is lower than the internal pressure of the second delivery pipe 300, so that the pressure of the gas sprayed from the second delivery pipe 300 through the nozzle 400 into the accommodating chamber 101 can be lower than the internal pressure of the accommodating chamber 101, so that the gas toward the accommodating chamber 101 can block the water vapor in the accommodating chamber 101. In this case, the gas in the second delivery pipe 300 can be pressurized gas.

[0066] In addition, in another feasible implementation manner, the internal pressure of the tank body 100 is lower than the spray pressure of the nozzle 400 , and the internal pressure of the tank body 100 is lower than the internal pressure of the second delivery pipe 300 .

[0067] It can be understood that the internal pressure of the tank body 100 is lower than the injection pressure of the nozzle 400, so that the gas pressure injected into the receiving chamber 101 through the nozzle 400 can be lower than the internal pressure of the receiving chamber 101, so that the gas toward the receiving chamber 101 can block the water vapor in the receiving chamber 101, in this case, the nozzle 400 can be a high-pressure nozzle 400. The internal pressure of the tank body 100 is lower than the internal pressure of the second delivery pipe 300, so that the gas pressure injected into the receiving chamber 101 through the nozzle 400 from the second delivery pipe 300 can be lower than the internal pressure of the receiving chamber 101, so that the gas toward the receiving chamber 101 can block the water vapor in the receiving chamber 101, in this case, the gas in the second delivery pipe 300 can be pressurized gas.

[0068] It is understandable that there is no limitation on the setting method of the gas pressure, and it can be selected according to actual use requirements, as long as the pressure of the gas sprayed by the nozzle 400 is greater than the internal pressure of the accommodating chamber 101.

[0069] It should be noted that the internal pressure of the tank body 100 provided in the embodiment of the present application is less than 0.2 MPa.

[0070] It should be noted that the pressure of the gas sprayed at the nozzle 400 provided in the embodiment of the present application is 0.4 MPa to 1.0 MPa.

[0071] It can be understood that the pressure at the nozzle 400 is greater than the internal pressure of the tank body 100. Under the action of the air pressure difference, it is difficult for the water vapor in the tank body 100 to pass through the higher-pressure gas sprayed from the nozzle 400, and thus it is difficult to enter the first delivery pipe 200. The gas sprayed from the nozzle 400 can block the water vapor in the tank body 100 to extend the service life of the first delivery pipe 200.

[0072] It should be noted that if the pressure of the gas sprayed at the nozzle 400 is less than 0.4 MPa, the pressure difference between the pressure at the nozzle 400 and the internal pressure of the tank body 100 will decrease, causing the water vapor in the tank body 100 to pass through the gas sprayed at the nozzle 400 and enter the first delivery pipe 200, thereby reducing the service life of the first delivery pipe 200 and causing waste of the gas sprayed by the nozzle 400.

[0073] It should be noted that if the pressure of the gas sprayed at the nozzle 400 is greater than 1.0 MPa, the pressure difference between the pressure at the nozzle 400 and the internal pressure of the tank body 100 will become larger, causing the pressure value of the internal pressure of the tank body 100 to increase faster, resulting in the deterioration of the safety performance of the tank body 100, and causing the second delivery pipe 300 to have greater difficulty in delivering gas, thereby deteriorating the safety performance of the hydrolysis device.

[0074] It should be noted that there are many different connection modes between the first delivery pipe 200 and the second delivery pipe 300 . The connection modes between the first delivery pipe 200 and the second delivery pipe 300 are described below in turn by way of examples.

[0075] In a feasible implementation manner, the first delivery pipe 200 passes through the opening 102 and is sealedly connected to the opening 102 , and the second delivery pipe 300 passes through the opening 102 and is sealedly connected to the opening 102 .

[0076] It can be understood that the first delivery pipe 200 passes through the opening 102 and is sealed with the opening 102, and the second delivery pipe 300 passes through the opening 102 and is sealed with the opening 102, which can reduce the occurrence of slurry or water vapor in the containing chamber 101 leaking to the external environment through the tank body 100, thereby providing safety protection for the hydrolysis device.

[0077] like Figure 3 and Figure 4 As shown, in another feasible embodiment, the first delivery pipe 200 is sleeved in the second delivery pipe 300, the second delivery pipe 300 is sealed connected to the opening 102, and one end of the second delivery pipe 300 close to the opening 102 is sealed connected to one end of the first delivery pipe 200 close to the opening 102.

[0078] It is understandable that the second delivery pipe 300 is sealedly connected to the opening 102, which can reduce the occurrence of slurry or water vapor in the receiving chamber 101 leaking to the external environment through the tank body 100, thereby providing safety protection for the hydrolysis device. The first delivery pipe 200 is sleeved in the second delivery pipe 300, which can reduce the connection area between the second delivery pipe 300 and the first delivery pipe 200 and the tank body 100, so as to reduce the space occupied by the hydrolysis device and reduce the processing difficulty of the hydrolysis device. The end of the second delivery pipe 300 close to the opening 102 is sealedly connected to the end of the first delivery pipe 200 close to the opening 102, which can reduce the contact area between the gas in the second delivery pipe 300 and the receiving chamber 101, so as to reduce the waste of gas, and can slow down the increase in the pressure inside the receiving chamber 101, thereby providing safety protection for the tank body 100, so as to improve the safety performance of the hydrolysis device.

[0079] It is understandable that there is no limitation on the connection method between the first delivery pipe 200 and the second delivery pipe 300, and it can be selected according to actual use requirements.

[0080] like Figure 5 As shown, the hydrolysis device provided in the embodiment of the present application also includes: a connecting ring 500, which is arranged in the accommodating chamber 101, the inner ring of the connecting ring 500 is sealedly connected to the first conveying pipe 200, and the outer ring of the connecting ring 500 is sealedly connected to the second conveying pipe 300.

[0081] It can be understood that the setting of the connecting ring 500 can reduce the difficulty of connecting the first delivery pipe 200 and the second delivery pipe 300, and the setting of the connecting ring 500 can reduce the contact area between the gas in the second delivery pipe 300 and the containing chamber 101 to reduce gas waste, and can slow down the increase in pressure inside the containing chamber 101, thereby safely protecting the tank body 100 and improving the safety performance of the hydrolysis device.

[0082] It should be noted that the second delivery pipe 300 , the connecting ring 500 and the first delivery pipe 200 together enclose a delivery cavity, and the delivery cavity is connected to the accommodating cavity 101 through the nozzle 400 .

[0083] It is understandable that the provision of the delivery chamber can facilitate the accommodation of the gas. The delivery chamber is connected to the accommodation chamber 101 through the nozzle 400, so that the gas in the delivery chamber can be introduced into the accommodation chamber 101 through the nozzle 400 to improve the gas delivery efficiency.

[0084] It should be noted that there are multiple nozzles 400, and along the axial direction of the connecting ring 500, the multiple nozzles 400 are arranged at intervals on the connecting ring 500, and the nozzles 400 are arranged away from the side of the second conveying pipe 300 and toward the side close to the symmetry center of the first conveying pipe 200.

[0085] It is understandable that increasing the number of nozzles 400 can further reduce the occurrence of water vapor in the receiving chamber 101 entering the first delivery pipe 200. The nozzle 400 is arranged away from the side of the second delivery pipe 300 and toward the side close to the symmetry center of the first delivery pipe 200, which can improve the blocking of the gas sprayed by the nozzle 400 on the water vapor in the receiving chamber 101, thereby extending the service performance of the first delivery pipe 200.

[0086] It should be noted that there are various numbers of nozzles 400 that can be set. The numbers of nozzles 400 that can be set are described below with examples.

[0087] In a feasible implementation manner, two nozzles 400 are provided, and the two nozzles 400 are separately arranged on the connecting ring 500 along the axial direction of the connecting ring 500 , and along the radial direction of the connecting ring 500 , the two nozzles 400 are spaced apart.

[0088] It can be understood that the two nozzles 400 are arranged at intervals along the radial direction of the connecting ring 500, which can reduce the occurrence of water vapor in the accommodating cavity 101 entering the first delivery pipe 200, and can improve the blocking effect of the gas sprayed by the nozzle 400 on the water vapor in the accommodating cavity 101, so as to extend the service performance of the first delivery pipe 200.

[0089] In another feasible implementation, three nozzles 400 are provided, and the three nozzles 400 are arranged on the connecting ring 500 along the axial direction of the connecting ring 500, and the line connecting two adjacent nozzles 400 and the center of the connecting ring 500 is arranged at an angle of 120 degrees.

[0090] It can be understood that the line connecting the centers of two adjacent nozzles 400 and the connecting ring 500 is set at an angle of 120 degrees, which can reduce the occurrence of water vapor in the accommodating cavity 101 entering the first delivery pipe 200, and can improve the blocking effect of the gas sprayed by the nozzle 400 on the water vapor in the accommodating cavity 101, so as to extend the service performance of the first delivery pipe 200.

[0091] It is understandable that there is no limit to the number of nozzles 400 that can be set, and the number can be selected according to actual usage requirements.

[0092] It should be noted that the embodiment of the present application provides that a plurality of first delivery pipes 200 are provided, and the plurality of first delivery pipes 200 are arranged at intervals; a plurality of openings 102 are provided, and the plurality of openings 102 are arranged in a one-to-one correspondence with the plurality of first delivery pipes 200.

[0093] It is understandable that increasing the number of openings 102 can improve the transport efficiency between the dryer and the tank body 100, or improve the transport efficiency between the tank body 100 and the chlorosilane collection tank, so as to improve the slurry treatment efficiency of the hydrolysis device.

[0094] It should be noted that there are various numbers of the first delivery pipes 200 , and the numbers of the first delivery pipes 200 are exemplified below.

[0095] In a feasible implementation manner, two first delivery pipes 200 are provided, and the two first delivery pipes 200 are arranged at intervals.

[0096] It should be noted that, when two first conveying pipes 200 are provided, two openings 102 are provided. Among the two first conveying pipes 200 and the two openings 102, one first conveying pipe 200 and one opening 102 are provided correspondingly.

[0097] In another feasible implementation manner, three first conveying pipes 200 are provided, and the three first conveying pipes 200 are arranged at intervals.

[0098] It should be noted that, when three first conveying pipes 200 are provided, three openings 102 are provided. Among the three first conveying pipes 200 and the three openings 102 , one first conveying pipe 200 and one opening 102 are provided correspondingly.

[0099] It can be understood that there is no limit to the number of first delivery pipes 200 that can be set, and the number can be selected according to actual usage requirements.

[0100] It should be noted that the embodiment of the present application provides a plurality of second delivery pipes 300 , and the plurality of first delivery pipes 200 and the plurality of second delivery pipes 300 are arranged in one-to-one correspondence.

[0101] It can be understood that increasing the number of second delivery pipes 300 can further reduce the flow of water vapor in the accommodating chamber 101 toward the first delivery pipe 200. The corresponding arrangement of a first delivery pipe 200 and a second delivery pipe 300 can further improve the safety performance of the hydrolysis device to extend the service life of the first delivery pipe 200.

[0102] It should be noted that, when the number of first delivery pipes 200 is varied, the number of second delivery pipes 300 is varied. The number of second delivery pipes 300 is described below with examples.

[0103] In a feasible implementation, when two first delivery pipes 200 are provided, two second delivery pipes 300 are provided, and among the two first delivery pipes 200 and the two second delivery pipes 300, one first delivery pipe 200 and one second delivery pipe 300 are provided correspondingly.

[0104] In another feasible embodiment, when three first conveying pipes 200 are provided, two or three second conveying pipes 300 are provided, and among the three first conveying pipes 200 and the three second conveying pipes 300, one first conveying pipe 200 and one second conveying pipe 300 are provided correspondingly.

[0105] It is understandable that when there is no limit on the number of first delivery pipes 200, there is no limit on the number of second delivery pipes 300, and they can be selected according to actual usage requirements. It is only necessary to ensure that one first delivery pipe 200 and one second delivery pipe 300 are correspondingly set.

[0106] The hydrolysis device provided in the embodiment of the present application further includes: a flow meter, which is disposed in the second delivery pipe 300 and is configured to detect the flow rate of the gas in the second delivery pipe 300 .

[0107] It can be understood that the flow meter is used to detect the internal pressure of the second delivery pipe 300 so as to detect the second delivery pipe 300 and thus provide safety protection for the second delivery pipe 300 .

[0108] It should be noted that if the reading of the flow meter is less than the preset value, there is a reduction in diameter, blockage or leakage in the second delivery pipe 300, which can remind the operator to inspect the second delivery pipe 300 and enable the operator to judge the air tightness of the second delivery pipe 300 to safely protect the second delivery pipe 300.

[0109] An embodiment of the present application provides a slurry processing device, including the hydrolysis device provided by any of the above embodiments.

In addition, such phrases do not necessarily refer to the same embodiment.
