Description

Technical Field

[0001] This invention relates to the field of dissolved gas technology, and in particular to a high-efficiency dissolved gas system and control method based on cloud-edge collaboration. Background Technology

[0002] In the petrochemical industry, processes such as oil extraction and refining generate a large amount of wastewater containing oil and suspended solids. In the water treatment process, gas-liquid mixing is a key step.

[0003] The process of wastewater swirling allows for the stretching of chemical molecules and the dissolution of compressed gases. Swirling also enhances the capture of oil droplets and particulate matter by the chemical molecules.

[0004] The common methods for treating wastewater and waste gas in China are to mix wastewater with special gases or waste gas with special liquids to remove wastewater and waste gas.

[0005] Besides wastewater treatment, precise control of gas dissolution is required in many other scenarios, such as chemical production.

[0006] Chinese Patent Publication No. CN214076002U discloses a gas-liquid mixing device, including a vortex mixing cylinder with a water outlet at the top, a guide pipe, an air inlet pipe, and a water inlet pipe. Several air inlets are arranged at an angle along the outer wall of the vortex mixing cylinder, with the direction of entry of the air inlets being the same as the direction of liquid rotation. The guide pipe is installed at the bottom of the vortex mixing cylinder, and the water inlet pipe is installed on the outer wall of the vortex mixing cylinder. It can be seen that the above technical solution has the following problem: it does not take into account the coordination of the input rate of liquid and gas according to the liquid processing situation, which affects the dissolved gas efficiency. Summary of the Invention

[0007] To address this issue, the present invention provides a high-efficiency dissolved gas system and control method based on cloud-edge collaboration, which overcomes the problem in the prior art that the input rates of liquid and gas are not coordinated according to the liquid processing conditions, thus affecting the dissolved gas efficiency.

[0008] On one hand, the present invention provides a high-efficiency dissolved air system based on cloud-edge collaboration, comprising:

[0009] The shell has several partitions inside to form independent chambers;

[0010] An infusion module for introducing a liquid to be treated into a housing, including an inlet on one side of the housing for introducing the liquid to be treated into an independent chamber within the housing;

[0011] The swirling module includes several swirling cores installed in each chamber to form vortices in the liquid to be treated, swirling cores for sequentially connecting adjacent chambers, and several sets of connector pipes and connecting pipes for sequentially allowing the liquid to be treated to flow between the chambers.

[0012] The gas delivery module is used to deliver compressed gas into the hydrocyclone core, including a compressed gas port on one side of the outer shell for inputting compressed gas into the hydrocyclone core for mixing with the liquid to be treated under the action of eddy current.

[0013] The liquid outlet module is used to output the liquid after gas-liquid mixing, including an outlet opened on the side of the housing away from the inlet.

[0014] The detection module includes several pressure monitors for detecting the pressure of each hydrocyclone core, several turbidity sensors installed on each connecting pipe for detecting liquid turbidity, several flow meters installed on each connecting pipe for detecting liquid flow rate, and several laser scattering sensors installed on the side wall of the hydrocyclone core for detecting bubble density.

[0015] A pressure relief module, located on one side of the housing, is designed to automatically open when the pressure in the independent chamber exceeds a preset critical pressure, in order to release the excessive pressure.

[0016] The analysis module, which is connected to the infusion module, the gas delivery module, the detection module, and the pressure relief module, is used to periodically determine whether the operating status of the infusion module is qualified based on the average value of the liquid turbidity obtained by each turbidity sensor, and when the operating status of the infusion module is determined to be abnormal, to correct the operating parameters of the infusion module or the gas delivery module based on the average pressure of each hydrocyclone core, including adjusting the gas input rate of the compressed gas in the gas delivery module to the corresponding value, adjusting the liquid input rate of the liquid to be processed in the infusion module to the corresponding value, or issuing a blockage alarm message for the hydrocyclone orifice;

[0017] An alarm module, which is connected to the analysis module, is used to issue corresponding alarm information based on the judgment result of the analysis module.

[0018] Furthermore, the hydrocyclone core includes,

[0019] A plurality of swirling holes are provided, each of which is formed on the cylindrical wall of the hydrocyclone core and is formed along the tangent of the inner cylindrical circle of the hydrocyclone core, so as to form a vortex in the liquid to be treated.

[0020] The analysis module is used to determine whether the operating status of the infusion module is qualified based on the average value of the liquid turbidity obtained from each turbidity sensor, including:

[0021] The average value of the liquid turbidity obtained by each turbidity sensor is recorded as the average turbidity.

[0022] If the average turbidity is less than or equal to the first preset turbidity, the infusion module is determined to be in a qualified operating state, and the infusion module is controlled to continue to operate with the current operating parameters.

[0023] If the average turbidity is less than or equal to the second preset turbidity and greater than the first preset turbidity, then the detection point-turbidity curve is plotted according to the liquid flow sequence, the variance of the slope at each node is calculated, and the operating parameters of the infusion module are determined to be qualified based on the calculated slope variance.

[0024] If the average turbidity is greater than the second preset turbidity, the infusion module is determined to be in an abnormal operating state, and the operating parameters of the infusion module or gas delivery module are corrected based on the average pressure of each hydrocyclone core.

[0025] Furthermore, the analysis module is used to determine whether the operating parameters of the infusion module are qualified based on the slope variance, including:

[0026] If the slope variance is less than or equal to the preset slope variance, the first preset turbidity and the second preset turbidity are adjusted to the corresponding values ​​based on the slope variance.

[0027] If the slope variance is greater than the preset slope variance, the infusion module is determined to be in an abnormal operating state, and the operating parameters of the infusion module or gas delivery module are corrected based on the average pressure of each hydrocyclone core.

[0028] Furthermore, the analysis module is used to adjust the first preset turbidity and the second preset turbidity to corresponding values ​​based on the slope variance, wherein,

[0029] The increase in the first and second preset turbidity is proportional to the slope variance.

[0030] Furthermore, the analysis module is used to correct the operating parameters of the infusion module or gas delivery module based on the average pressure value, including:

[0031] If the average pressure is less than or equal to the first preset average pressure, the gas input rate of the compressed gas in the gas delivery module will be adjusted to the corresponding value based on the average pressure.

[0032] If the average pressure is less than or equal to the second preset average pressure and greater than the first preset average pressure, the operating parameters of the liquid delivery module or gas delivery module are corrected based on the variance of the pressure of each hydrocyclone core.

[0033] If the average pressure is greater than the second preset average pressure, the liquid input rate of the liquid to be processed in the infusion module will be adjusted to the corresponding value based on the average bubble density in each hydrocyclone core.

[0034] Furthermore, the analysis module is used to adjust the gas input rate of the compressed gas in the gas delivery module to a corresponding value based on the average pressure, wherein,

[0035] The increase in gas input rate is inversely proportional to the average pressure.

[0036] Furthermore, the analysis module is used to correct the operating parameters of the infusion module or gas delivery module based on the pressure variance, including:

[0037] If the pressure variance is less than or equal to the preset pressure variance, the gas input rate of the compressed gas in the gas delivery module will be adjusted to the corresponding value based on the average pressure.

[0038] If the pressure variance is greater than the preset pressure variance, the control alarm module will issue a blockage alarm message for the vortex orifice.

[0039] Furthermore, the analysis module is used to adjust the liquid input rate of the liquid to be processed in the infusion module to a corresponding value based on the average bubble density within each hydrocyclone core, wherein,

[0040] The decrease in liquid input rate is inversely proportional to the average bubble density.

[0041] Furthermore, the analysis unit, after adjusting the liquid input rate, obtains the average flow rate of the liquid obtained by each flow meter.

[0042] If the average flow rate is less than or equal to the preset average flow rate, the gas input rate of the compressed gas in the gas delivery module will be corrected to the first gas correction rate.

[0043] If the average flow rate is greater than the preset average flow rate, the infusion module will continue to operate using the current operating parameters.

[0044] On the other hand, the present invention also provides a highly efficient dissolved gas control method using the above-mentioned highly efficient dissolved gas system, comprising:

[0045] S1, the liquid to be treated is introduced into the independent chamber from the water inlet, and the compressed gas is introduced into the hydrocyclone core from the compressed gas port. The liquid to be treated enters the hydrocyclone core set in the independent chamber through the swirling hole to form a swirling flow.

[0046] S2, the liquid to be treated enters the subsequent independent chambers in sequence through the connector pipe and the connecting pipe, and a swirling flow is formed in the inner cavity of the hydrocyclone core in each independent chamber;

[0047] S3, respectively detect the pressure of each hydrocyclone core, the turbidity of the liquid in each connecting pipe, the liquid flow rate in each connecting pipe and the bubble density in the hydrocyclone core;

[0048] S4, determine whether the operating status of the infusion module is qualified based on the average value of the turbidity of each liquid, and when the operating status of the infusion module is determined to be abnormal, correct the operating parameters of the infusion module or the gas delivery module based on the average pressure of each hydrocyclone core, including adjusting the gas input rate of the compressed gas of the gas delivery module to the corresponding value, adjusting the liquid input rate of the liquid to be processed in the infusion module to the corresponding value, or issuing a blockage alarm message for the hydrocyclone orifice.

[0049] Alternatively, determine that the infusion module is in good working order and control the infusion module to continue operating at the current operating parameters.

[0050] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting up a shell, infusion module, cyclone module, gas delivery module, liquid outlet module, detection module, pressure relief module, and analysis module, the operating status of the infusion module is periodically determined based on the average value of liquid turbidity obtained by each turbidity sensor. When the operating status of the infusion module is determined to be abnormal, the operating parameters of the infusion module or gas delivery module are corrected based on the average pressure of each cyclone core. This includes adjusting the gas input rate of the compressed gas in the gas delivery module to a corresponding value, adjusting the liquid input rate of the liquid to be processed in the infusion module to a corresponding value, or issuing a blockage alarm message for the cyclone orifice. The input rates of liquid and gas are coordinated according to the liquid processing situation, thereby improving the dissolved gas efficiency. Attached Figure Description

[0099] Specifically, the first preset average pressure Y1 is selected within the range of [0.2MPa, 0.3MPa], and the second preset average pressure Y2 is selected within the range of [0.5MPa, 0.55MPa].

[0100] Specifically, the analysis module is used to adjust the gas input rate of the compressed gas in the gas delivery module to a corresponding value based on the average pressure.

[0113] The decrease in liquid input rate is inversely proportional to the average bubble density.

[0114] In this embodiment, optionally,

[0115] Compare the average bubble density with the first preset average density and the second preset average density;

[0116] If the average bubble density is less than or equal to the first preset average density, the liquid input rate will be adjusted to 0.73 times the initial liquid input rate.

[0122] If the average flow rate is greater than the preset average flow rate, the infusion module will continue to operate using the current operating parameters.

[0123] Specifically, the preset average flow velocity is selected within the range of [0.6 m / s, 0.7 m / s].

[0124] Specifically, in S1, the liquid to be treated is introduced into the independent chamber from the water inlet, and the compressed gas is introduced into the hydrocyclone core from the compressed gas port.

[0128] Alternatively, determine that the infusion module is in good working order and control the infusion module to continue operating at the current operating parameters.

[0129] Specifically, in the S1 process, the chemical reagent molecules in the liquid to be treated are stretched, and at the same time, compressed gas enters the core of the hydrocyclone through the compressed gas port. Under the action of the vortex, it begins to mix with the liquid to be treated, completing the initial gas dissolution process.

[0130] Specifically, in the S2 process, the capture of oil droplets and particulate matter by the agent molecules in the liquid to be treated is further enhanced, while compressed gas is continuously dissolved into the wastewater. As the wastewater flows within the core of the multi-stage hydrocyclone, large bubbles are broken down into smaller bubbles by the elongated cyclone holes. The small bubbles in the dissolved air water gradually become uniform and stable, resulting in higher compressed gas utilization efficiency.
