Description

Technical Field

[0001] The utility model relates to a micro-nano bubble device, more specifically to a micro-nano bubble water mist jet device. Background Art

[0002] Drilling and blasting is one of the main construction methods for underground projects such as underground chambers, tunnels, and mines in my country. The blasting stage mainly includes three stages: drilling, charging, and detonation. Due to the small diameter of the drill hole, the explosive releases a huge amount of energy in a short time, thereby breaking the rock and completing the face excavation. Due to the use of industrial explosives, a large amount of dust will be generated during the blasting process. Under the disturbance of the airflow in the tunnel, PM 10 The particles within the tunnel form Brownian motion and generate dust clouds, resulting in poor dust settling effects. The poor ventilation in the narrow and long construction space makes it difficult to discharge the dust cloud. Even after several hours of blasting, the dust concentration in the tunnel is still high. The poor air environment in the tunnel greatly reduces the construction efficiency of the construction workers, so the dust removal efficiency problem is very prominent. On the other hand, blasting also produces a large amount of carbon monoxide (CO), nitrogen oxides (NO X ), ammonia (NH3), hydrogen sulfide (H2S), sulfur dioxide (SO2) and other toxic and harmful gases cause serious pollution to the construction environment, which not only affects the construction period, but also poses a great threat to the physical and mental health of tunnel construction workers.

[0003] The existing dust control mainly starts from the five aspects of "reduction, reduction, discharge, removal and blocking", which can reduce dust to a certain extent, but there are still some shortcomings such as poor treatment effect of small dust particles, large amount of water resources required, and secondary pollution outside the cave. In addition, physical means have limited effect on removing toxic and harmful gases and their corresponding pungent odors generated by blasting.

[0004] The Chinese patent with the publication number CN214611733U discloses a novel ozone micro-nano bubble water generating device, including a water pump, a micro-nano bubble generator, an ozone generator and a molecular sieve oxygen generator; the water pump is connected to the outlet of the ozone generator through a gas connecting pipe; the ozone generator is connected to the molecular sieve oxygen generator; an ozone high-voltage and high-frequency power supply is installed on one side of the ozone generator; the inlet of the water pump is connected to the siphon through a pipeline; the siphon is connected to the water inlet; the outlet of the water pump is connected to a mixing tank; one end of the mixing tank is connected to a water outlet; the micro-nano bubble generator is installed on the pipeline of the water outlet. The device makes full use of the comprehensive effects of the strong oxidation ability of ozone, the high adsorption of the extremely large specific surface of nano bubbles and the high energy when the bubbles burst, so as to improve the washing efficiency of fabric desizing, and achieve the effect of reducing the number of long-line washing tanks, shortening the washing time, reducing the emission of organic matter and reducing water consumption. The device can only be used to improve the washing efficiency of fabric desizing by preparing ozone micro-nano bubble water. Utility Model Content

[0005] The utility model aims to provide a micro-nano bubble water mist jet device, which can complete the encapsulation and sedimentation of dust and the removal of toxic and harmful gases in a relatively short time.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A micro-nano bubble water mist jet device comprises a micro-nano bubble water generating device and a mixing tank, wherein a water inlet of the mixing tank is connected to a water outlet of the micro-nano bubble water generating device, an air inlet of the mixing tank is connected to an air outlet of a high-pressure gas storage device, and a nozzle is installed at the air outlet of the mixing tank.

[0008] The micro-nano bubble water generating device may be a micro-nano bubble water generating device in the Chinese patent with publication number CN214611733U. The high-pressure gas storage device may be a high-pressure gas releasing device in the Chinese patent with publication number CN220287141U.

[0009] The high-pressure gas in the high-pressure gas storage device is pumped into the mixing tank, and the compressed air and water are mixed in the gas dissolving tank, and then the micro-nano bubble water is sprayed out from the nozzle. The utility model sprays the micro-nano bubble water instantly through the high-pressure gas source, and forms a high-speed, high-pressure water jet, which can quickly form a water mist curtain near the face, disperse more evenly, permeate the entire tunnel space, and can immediately suppress the spread of dust.

[0010] According to the embodiments of the present invention, the present invention can be further optimized. The following is the technical solution formed after optimization:

[0011] An air dissolving tank is installed on the upper part of the micro-nano bubble water generating device, and the air dissolving tank is respectively connected to the water inlet and the air compressor. A rotating shaft is installed at the water outlet of the air dissolving tank, and an impeller is fixed on the rotating shaft.

[0012] The gas-liquid mixture produced in the gas dissolving tank is dispersed by the high-speed rotation of the impeller to form micro-nano bubble water.

[0013] In one of the preferred embodiments, the water outlet of the air dissolving tank is opened at the bottom of the air dissolving tank, and the rotating shaft and the impeller are installed directly below the water outlet of the air dissolving tank.

[0014] In one of the preferred embodiments, the water outlet of the micro-nano bubble water generating device is opened near the impeller.

[0015] In one of the preferred embodiments, the high-pressure gas storage device includes a high-pressure gas source, in which a second pressure monitoring module is installed, and a solenoid valve switch and a pressure regulating valve are sequentially installed at the gas outlet of the high-pressure gas source, which is then connected to the gas inlet of the mixing tank, and the controller is electrically connected to the second pressure monitoring module and the solenoid valve switch, respectively.

[0016] The controller receives the pressure monitoring signal from the second pressure monitoring module. The controller receives the signal from the second pressure monitoring module and controls the solenoid valve switch and the pressure regulating valve to inject the high-pressure gas in the high-pressure gas source into the mixing tank. The micro-nano bubble water in the mixing tank is sprayed in a mist form through the nozzle under the action of high pressure.

[0017] In one of the preferred embodiments, the high-pressure gas source storage tank contains compressed air or CO2.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The utility model adopts the method of pressure-dissolving gas and impeller-dispersing gas to improve the efficiency of bubble generation, forming micro-nano bubble water with high specific surface area, higher gas solubility and longer gas residence time, which has a better effect on encapsulating dust and harmful gases.

[0020] Micro-nano bubble water is sprayed instantly through a high-pressure air source to form a high-speed, high-pressure water jet, which can quickly form a water mist curtain near the face, disperse more evenly, permeate the entire tunnel space, and suppress dust diffusion in the first place.

[0021] On the other hand, the micro-nano bubble water is ruptured and collapsed by the high-pressure shear force, and the pressure is released instantly to form ultra-high-speed microjets and local ultra-high temperatures. The microjets enhance the ability to wrap fine dust, and under the action of air flow disturbance and gravity sedimentation, they can quickly suppress the diffusion of dust near the palm face and accelerate sedimentation.

[0022] Local ultra-high temperature enhances the reaction activity and speeds up the reaction rate, which can quickly decompose H2S, SO2, NH3, and NO X And other odorous gases. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0026] Example 1 A micro-nano bubble water mist jet device, the structure diagram of which is shown in FIG. Figure 1 As shown, the outlet and water inlet 1 of the air compressor 2 are connected to the air dissolving tank 3; the outlet of the air dissolving tank 3 is arranged above the impeller 5; the mixing tank 6 is connected to the outlet of the micro-nano bubble water through a connecting pipe; the high-pressure gas in the high-pressure gas source storage tank 10 is injected into the mixing tank and the micro-nano bubble water is sprayed out from the nozzle 13. The nozzle 13 is installed on the mixing tank 6 and is arranged around the smoke source.

[0027] During operation, first, water enters the air dissolving tank 3 through the water inlet 1, and the air compressor 2 absorbs and compresses the external air, and then blows the compressed air into the air dissolving tank 3 to form a pressurized gas-liquid mixture. After the pressurized gas-liquid mixture flows out, it is dispersed by the high-speed rotating impeller 5 to form micro-nano bubble water, and then enters the mixing tank 6 through the pipeline.

[0028] The first pressure monitoring module 7 is arranged in the mixing tank 6, which can monitor the pressure change in the mixing tank in real time and transmit the signal to the controller 8. Similarly, the second pressure monitoring module 9 is arranged in the high-pressure gas source storage tank 10, and the pressure signal is transmitted to the controller 8. Combining the two pressure signals, the controller 8 controls the solenoid valve switch 11 and the pressure regulating valve 12 to inject the high-pressure gas in the high-pressure gas source storage tank 10 into the mixing tank. Under the action of high pressure, the micro-nano bubble water in the mixing tank is sprayed in a mist through the nozzle 13.

[0029] The nozzle 8 is arranged around the smoke source, and the sprayed micro-nano bubble water mist fully contacts and adsorbs the smoke solid particles, turning them into large particles and settling rapidly, thereby achieving the dust reduction effect. The micro-nano bubbles are collapsed under high pressure and release local ultra-high-speed jets and ultra-high temperatures instantly, strengthening the wrapping effect of smoke particles and the oxidation process of harmful gases, thereby achieving rapid dust reduction and deodorization in chamber blasting.
