Technical field

The present disclosure relates to the technical field of liquid processing devices, and in particular, to a pressurized turbulent mixing device, a liquid processing method, a cyanobacteria processing device, and a cyanobacteria processing method.

Background technique

At present, eutrophication of water bodies has gradually become a major environmental issue that affects people's livelihood, can cause water quality deterioration and damage the ecological environment. Among them, cyanobacteria blooms are a typical feature of eutrophic water bodies. At present, domestic and foreign algae removal technologies are mainly divided into three categories: physical algae removal, chemical algae removal, and biological algae removal. Physical algae removal technology mainly includes fishing, filtering, covering, air flotation, etc. Compared with other algae removal methods, physical algae removal has the advantages of direct effect and no secondary pollution.

The current physical algae removal method mainly uses a liquid processing device to extract water from cyanobacteria, pressurize and spray, and strongly impact the cyanobacteria to perform cyanobacteria treatment. For example, Chinese invention (CN200820152292.0), which discloses a cyanobacteria processing device, includes a double hull, and an electric control box connected to the double hull. It is characterized in that a collector is installed at the tail of the double hull, There is a replaceable filter frame between the ship's bottom frame and the double hull. The pressure pump and the spray barrel are installed on the bottom frame. There is a pressure pipe between the pressure pump and the spray barrel. The pressure pipe extending into the spray barrel is connected, the drain line is connected to the spray barrel, and a baffle is installed in the spray barrel.

Its shortcoming is that the physical method of spraying is used to treat cyanobacteria, that is, the pressurized water-containing algae is sprayed onto the baffle at a high speed by a spray head, and then falls by its own weight, so that no turbulent flow can be formed. In addition, it handles cyanobacteria-containing liquids by pressurizing, spraying, and colliding. The cell wall of cyanobacteria ruptures, and it cannot become food for other aquatic animals. It breaks the biological chain, so that the ecosystem can not reach a new balance due to new blows. At the same time, the cell wall of the cyanobacteria ruptured, causing toxins (such as microcystins) in the cells of the cyanobacteria to flow out, causing secondary pollution of the water body and bringing hidden dangers to human health.

In addition, in the field of cosmetics and pharmaceuticals, liquids need to be processed. It needs to homogenize and mix various animal and plant tissues. It also needs efficient dispersion of organic and water, incompatible two liquids, Emulsification and extraction of trace organic compounds, fat-soluble substances, organic lysozymes, and soluble substances in water. In the field of cosmetics and pharmaceuticals, there are both occasions where it is necessary to break the cell wall and promote absorption by the human body, and there are occasions where it is not necessary to break the cell wall and avoid loss of nutrients. Most of the existing processing devices are also realized by stirring, which can neither form turbulence nor flexibly choose whether to break the cell wall according to the occasion.

Summary of the invention

The turbulent flow formed by the pressurized liquid has a certain impact force inside, which is less than the impact force formed by spraying. When the processed liquid is sprayed through the nozzle to the inner surface of the cylinder, a certain collision occurs. The liquid is dispersed, and then converges to form a new turbulent flow. Continue to spray through the hollow tube and then through the nozzle to the inner surface of the cylinder to form a new turbulent flow, which repeats the cyclic flow, thereby creating a stable and continuous flow of the liquid being processed.

The spray impact device, that is, the existing cyanobacteria treatment device, presses the raw water into the water after spraying. The impact force of the impact plate will reduce a part of the cyanotoxin, that is, microcystin; the pressurized turbulent mixing device is mixed by pressurization, turbulence, and air introduction, resulting in a process of repeated pressurization and decompression, resulting in cyanotoxin, which is the microcapsule Algae toxin is reduced, and it is reduced by half after standing for three days in the wild. With this cyanobacteria treatment device, microcystins are reduced to one fifth after treatment due to the micro-bubbles generated by ozone and the irradiation of ultraviolet light. After 3 days, it will disappear below the limit of quantification.

In another embodiment of the present disclosure, as shown in FIGS. 8 and 11, the pressure turbulent mixing device of the above cyanobacteria processing device further includes a left end cover 25, which is disposed at the left end of the left chamber 22 and enables the left chamber. 22% sealed, at least two deflectors 251 protruding from the inner wall of the cylinder 2 are convexly arranged on the left end cover 25, and the deflectors 251 are distributed in a circular array with the axis of the left end cover 25 as an array, of which one guide The flow plate 251 is disposed below the liquid discharge pipe 12 and is disposed obliquely toward the liquid discharge pipe 12. One end of the deflector 251 is fixedly connected to the left end cover 25, and one end thereof abuts the partition plate 21. It also includes a vent tube 26 and a gas storage chamber 27. The vent tube 26 penetrates the outer wall of the left chamber 22, and one end is close to the nozzle of the liquid outlet pipe 12, and the other end is connected to the gas storage chamber 27.

Hit the next deflector and continue to flow along the inner wall of the column. The liquid being processed circulates and the pressure changes continuously, and then enters the right chamber through the hollow tube. The deflector is arranged below the outlet pipe and is inclined toward the outlet pipe, that is, a negative pressure is formed at the nozzle of the outlet pipe, which helps the flow of the liquid to be treated and ruptures the cyanobacteria cells. The deflectors are distributed in a circular array with the axis of the left end cover as an array, so that the inclination of the deflectors is constantly changing, which helps to change the pressure value in the cylinder, causing the effect of pressure or decompression, and increasing the impact of cyanobacteria. Point to rupture cyanobacteria cells, thereby promoting the treatment effect of the present disclosure.

The pressure changes, thereby promoting the processing effect of the present disclosure. The air in the gas storage chamber enters the left chamber through the vent pipe, and a negative pressure is formed, which makes the cyanobacteria cells easy to break, and one end of the vent pipe is close to the nozzle of the outlet pipe, that is, the distance between the air introduced by the vent pipe and the liquid introduced by the outlet pipe. It can be introduced into the deflector more recently, which not only helps to mix the air with the liquid to be treated, improves the dissolved oxygen value of the liquid to be treated, but also can aggravate the change in the pressure value, which is helpful to the liquid of the present disclosure.

The cyanobacteria treatment method can effectively transform the population cells into dispersed single cells through the steps of first pressurizing, forming a turbulent flow, and finally adding air mixing, so that it can be widely used in the fields of water quality treatment, cosmetics, medicine and the like. The device used in the cyanobacteria treatment method includes a pressurized turbulent mixing device. The cylinder may be in the shape of a cylinder.

The cyanobacteria processing method uses a turbulent flow formed by a pressurized liquid, which has a certain impact force inside and is smaller than the impact force formed by spraying. When the processed liquid is sprayed on the inner surface of the cylinder through a nozzle, a certain collision occurs. The processed liquids are dispersed and then converge to form a new turbulent flow. Continue to spray through the hollow tube and then through the nozzle to the inner surface of the cylinder to form a new turbulent flow. Repeat the cyclic flow to produce a turbulent flow to the processed liquid. The stable and continuous impact force can isolate population cells to a certain extent, so the present disclosure can smoothly and continuously change population cells such as cyanobacteria into dispersed single cells through turbulent flow, which can effectively alleviate the outbreak of populations such as cyanobacteria blooms. Water quality disasters. Moreover, the impact force generated by the turbulent flow is relatively stable and continuous, which can have a small and continuous impact on the cell wall of the cyanobacteria cells, which can ensure the integrity of the cell wall of the cyanobacteria cells to a certain extent and prevent the internal toxin from flowing out. In addition, the pressurized liquid can be instantly mixed with other gases or liquids under the combined effect of pressure and turbulence, so the present disclosure can fully and uniformly mix the liquid being processed, so that it can be applied to the fields of cosmetics and pharmaceuticals where liquids need to be processed. The occasion.

Furthermore, the present disclosure uses the left chamber as the first reaction chamber and the right chamber as the second reaction chamber. By dividing the column into two communicating reaction chambers, the liquid in the treated liquid is fully and fully dispersed. Swarm cells can also enhance the effect of dispersing.

The introduced air can be introduced into the air stored in the storage room or directly into the outside of the cylinder. During the process of liquid treatment, the treated liquid is sprayed to the inner surface of the cylinder through the nozzle. Because the mixing pipe cover is set outside the nozzle The treated liquid will stay in the mixing pipe for a short time. At this time, the air is sent into the mixing pipe through the inlet pipe. Due to the pressure, the air will instantly and uniformly mix with the liquid being treated, enhancing the cyanobacteria treatment effect.

Air can be stored in the storage room before being introduced. When the air in the storage room enters the mixing pipe, it will form bubbles and naturally form a negative pressure, causing the pressure in the cylinder to change. Therefore, the present disclosure can change the pressure value in the cylinder by regulating the introduction of air, resulting in the effect of pressurization or decompression, thereby promoting the processing effect of the present disclosure. To control the introduction of air, you can set a solenoid valve on the inlet pipe, or you can start by regulating the size of air bubbles that enter the mixing pipe when the air in the storage room enters the mixing pipe. Value, or change the pressure value of the booster pump. Among them, it has been found through experiments that when the introduction of regulated air is used to cause a decompression effect, the present disclosure has the best treatment effect on cyanobacteria. This is due to the nature of cyanobacteria, which is easy to break under negative pressure.

The storage room is located on the outside of the cylinder, which is convenient for the addition and replacement of gas or liquid in the storage room, and avoids being stored in the cylinder for a long time by the liquid, which reduces the probability of damage and increases the storage room. Of durability.

The mixed pipe is convexly arranged on the outer wall of the hollow pipe, which has a simple structure and is easy to manufacture. It can also extend the reaction time between the liquid or gas in the storage room and the liquid being processed, making it more effective. The mixing pipe and the nozzle are arranged coaxially, that is, when the liquid is ejected from the nozzle, it can be evenly filled in the mixing pipe, so that the liquid or gas introduced into the inlet pipe can react uniformly with the liquid being processed, making the processing effect better . When the axis of the nozzle is set perpendicular to the hollow tube, the mixed liquid can also be sprayed vertically on the surface of the right chamber through the mixing pipe, so that the mixed liquid is subject to the reaction force of the inner surface of the right chamber and the direction of the reaction. The flow direction is the same, so that the impact force is maximized, so that the present disclosure can disperse the population cells faster and more fully. It is also possible to make the height value of the mixing pipe greater than the height value of the nozzle. In this way, when the turbulent flow is sprayed through the nozzle to the inner surface of the right chamber, the mixing pipe is filled. The nozzle is convexly arranged on the outer wall of the hollow tube, and the inner diameter of the nozzle is gradually decreased along the axis of the nozzle, that is, the cross section of the nozzle can be a convex semi-conical shape, or a T-shape arranged in the opposite direction. The nozzle is sprayed on the inner surface of the cylinder along the axis of the nozzle. Since its inner diameter is gradually decreased in the direction of the spray, the flow channel inside the nozzle is gradually narrowed, which can give a certain impact to the liquid being processed. The force makes its spraying strength greater, and the formed turbulent flow has more impact force, so that the present disclosure can more effectively break up the population cells.

In other embodiments of the present disclosure, as shown in FIG. 7, FIG. 8, FIG. 9, and FIG. 10, the detoxification step. The method for treating cyanobacteria of the present disclosure further includes the following steps.

Make the liquid flow rate to 0.1-1.5m / s;

Introducing the liquid to be processed into the reaction chamber 6;

The ultraviolet lamp 8 provided in the reaction chamber 6 irradiates,

At the same time, ozone was introduced into the reaction chamber.

Among them, the introduced ozone may be the ozone stored in the storage room, or the ozone converted into oxygen by setting an ozone generator. To make the liquid flow rate to 0.1-1.5m / s, the following technical methods can be used. Through the pipeline speed meter 612, the liquid flow rate is monitored in real time and converted into an electric signal and fed back to the solenoid valve 611. The solenoid valve 611 automatically adjusts the flow rate of the water. A pressure adjustment valve can also be set on the output pipe to control the liquid Flow rate.

When cyanobacteria are toxic, they are irradiated with ultraviolet light and introduced ozone to treat cyanobacterial toxins. The treatment costs are low, energy consumption is low, and the amount of water is treated. The secondary pollution is small. When the cyanobacteria are non-toxic, the liquid processed by the pressurized turbulent mixing device can fully meet the requirements of water treatment and solve the bloom damage.

Among them, the ozone generator is provided with an ozone introduction pipe for transmitting ozone into the reaction chamber and an oxygen introduction pipe for transmitting oxygen into the reaction chamber. Two or more ozone introduction pipes are provided at the interface between the ozone introduction pipe and the reaction chamber. The ozone introduction pipes run through the reaction chamber and extend into the reaction chamber. The ultraviolet lamp can be an LED lamp with a built-in battery or an external power supply, and a transparent waterproof sleeve can be covered on the outside. The setting of the transparent waterproof cover can improve the durability of the ultraviolet light tube when it is used directly underwater, and the service life of the cyanobacterial toxin treatment device. In practical applications, the liquid treated by the existing cyanobacteria processing device can be passed into the reaction chamber through a water inlet pipe, and then irradiated by ultraviolet light to eliminate the endotoxin dissolved in the liquid. At the same time, the ozone generator converts oxygen into ozone, and Ozone is introduced into the reaction chamber to form micro-bubbles, that is, nano-bubbles, which generate negative pressure and mix with the liquid, thereby achieving the effect of treating cyanobacterial toxins, preventing the toxins from dissolving in water, causing secondary pollution of water bodies, and bringing hidden dangers to human health. In addition, the cyanotoxin treatment device treats cyanotoxin with ultraviolet light and ozone, which has low treatment cost, low energy consumption, large amount of water treatment, small secondary pollution, strong applicability, stable and reliable treatment effect, simple operation and maintenance, and mature technology.

Since the cyanobacterial toxin treatment device can be used in conjunction with other cyanobacterial treatment equipment, the liquid flow after the other cyanobacterial treatment equipment is large and the flow rate is fast, and the cyanobacterial toxin treatment device requires a slower flow rate to ensure the full irradiation of ultraviolet rays. Time allows it to completely eliminate toxins. Therefore, the cyanobacterial toxin treatment device is provided with a solenoid valve to regulate the liquid flow rate and flow rate in the water inlet pipe to achieve a deceleration effect and make the treatment effect better. A drain valve can also be provided on the water outlet pipe to control the opening and closing of the water outlet pipe to adapt to the actual liquid treatment process, for example, closing the water outlet pipe to increase the ultraviolet cyanotoxin treatment time, or opening the water outlet pipe to accelerate the ultraviolet cyanotoxin treatment . The setting of the pipeline speed meter is used to monitor the liquid flow rate in the water inlet pipe in real time and convert it into an electric signal to feed back to the solenoid valve on the water inlet pipe. The solenoid valve automatically adjusts the liquid flow rate in the water inlet pipe to avoid water inflow. The liquid flow rate in the tube is too fast, which makes the UV irradiation time insufficient and the treatment effect is not good.
