Description
Technical Field
The utility model belongs to the technical field of agricultural water-saving drip irrigation, and particularly relates to a drip irrigation belt for carbon dioxide water solution irrigation.
Background
As is well known, micro-irrigation represented by drip irrigation is the irrigation technology with the best agricultural water-saving effect and the fastest development in the international market, and since the drip irrigation technology is applied, the drip irrigation technology has a certain effect on controlling the salinization of soil due to the salt spraying effect of drip irrigation and the micro-water outlet, so that the drip irrigation has a yield increasing effect, but the drip irrigation is easy to cause the rise of the groundwater level along with the long-term drip irrigation, so that the saline-alkali secondary biochemical problem is caused, and the increase of the crop yield is inhibited. Research shows that carbon dioxide gas is dissolved in water and enters plant root soil along a drip irrigation zone, so that the saline development of the soil can be effectively controlled, the crop yield is increased, and meanwhile, carbon dioxide is fixed in the soil in an ionic state, thereby providing a new treatment way for reducing greenhouse effect, carbon fixation, changing waste into valuables and the like.
The domestic traditional drip irrigation emitter generally adopts a runner with an energy dissipation structure, and the pressure of the water containing pressure in the drip irrigation tape body is continuously reduced through the runner with the energy dissipation structure until the water reaches an outlet, so that the water flow at a water outlet is in a dripping shape and evenly drips into soil near the root of crops. Because the solubility of carbon dioxide gas in water reduces along with the pressure reduction, when the pressure reduction is carried out after the pressurized water dissipates energy, the carbon dioxide gas escapes from the water and rapidly diffuses into the drip irrigation tape main body in the drip irrigation flow channel, so that the loss of carbon dioxide is caused, the salt inhibition effect is influenced, meanwhile, the escaped gas is accumulated at the tail end of the drip irrigation tape body, the carbon dioxide aqueous solution can not reach the tail end, and the water outlet has no water outlet problem.
At present, drip irrigation belts applied in China are mostly studied on anti-blocking, water outlet and energy dissipation by different forms of flow channels. Chinese patent publication No. CN215346291U discloses a tesla valve type continuous strip drip irrigation tape, which comprises a tube tape, an inner runner provided in the tube tape, and a tesla type continuous strip adhered to the inner strip in the inner runner by hot melt and embedded in the inner runner. The utility model content of the specification introduces the function of accelerating the water flow and preventing the water flow from sucking backwards when the drip irrigation belt works and does not work. In the specific embodiment, the drip irrigation tape can save water, and under the condition of normal pressure irrigation, the carbon dioxide water solution can cause the water flow velocity of the water outlet to flush plant root soil too fast under the condition of non-energy dissipation, so that the drip irrigation effect is invalid. The Chinese patent with the publication number of 216722443U discloses a drip irrigation emitter based on the Tesla valve principle, wherein a direction identification groove which is consistent with the axial direction of the pipe is arranged on the pipe wall of the emitter pipe, a baffle is arranged in the identification groove, a Tesla valve runner is arranged in the baffle, a water inlet window is arranged at the inlet of the runner, and a water outlet is arranged at the outlet of the runner. The description of the utility model describes that the water irrigator continuously reduces the water flow pressure through the designed flow channel until the ideal outlet flow rate is reached. In the concrete embodiment, the water irrigator with the form is introduced to dissipate energy to reach required flow by arranging the valve clacks with corresponding quantity, the water pressure of the water flow is continuously reduced by the energy dissipation, when the water solution containing carbon dioxide irrigates through the water irrigator, carbon dioxide gas can continuously escape from the water solution, and the carbon dioxide gas can be rapidly diffused into a drip irrigation belt main body through a flow passage of the water irrigator, so that the loss of carbon dioxide is caused, the salt inhibition effect is influenced, meanwhile, the escaping gas is accumulated at the tail end of the drip irrigation belt body, the carbon dioxide water solution can not reach the tail end, and the water outlet has no water outlet problem.
The above patents do not consider that the carbon dioxide aqueous solution is used for irrigation, if the drip irrigation tape is directly used for carbon dioxide aqueous solution irrigation, after the carbon dioxide aqueous solution is depressurized and energy is dissipated through the energy dissipation flow channel, part of carbon dioxide gas can escape from the aqueous solution and enter the tape body from the water inlet to obstruct water flow, so that the water delivery efficiency of the drip irrigation tape is reduced, and secondly, the carbon dioxide gas can accumulate at the tail end of the drip irrigation tape to cause that the carbon dioxide aqueous solution can not reach the tail end, the tail end water outlet is free from water and can drip, so that the irrigation uniformity is affected, and on the other hand, the irrigator can not uniformly drip enough carbon dioxide-containing water to plant roots, so that the salt inhibition effect is poor, and the crop yield increasing effect is greatly reduced.

The Tesla valve-shaped flow passage is formed by connecting a plurality of passive one-way conduction valves with fixed geometric shapes end to end, the conduction direction of the conduction valves is from the wide-mouth end to the narrow-mouth end, and because the fluid has inertia, when passing through the valve from the wide-mouth end, the fluid expands and then compresses in the valve, and the pressure difference changes to generate thrust, thereby realizing one-way circulation. When fluid enters from the narrow-mouth end and exits from the wide-mouth end, the thrust generated by the pressure difference change is opposite to the advancing direction of the fluid, so that the fluid has a reverse flow blocking function.

According to the drip irrigation tape for carbon dioxide water solution irrigation, the length of the anti-reverse diffusion Tesla valve-shaped flow passage is larger than or equal to that of the energy dissipation flow passage, the energy dissipation flow passage with a certain length can achieve the purposes that water energy dissipation is reduced, the flow speed of water is reduced to be close to 0m/s, the water slowly flows out of the water outlet under the action of gravity, when carbon dioxide gas escapes from the energy dissipation flow passage and flows to the drip irrigation tape body along the anti-reverse diffusion Tesla valve-shaped flow passage, the reverse flow resistance characteristic is utilized, the airflow forward flow speed is reduced, the fluid speed cannot enter the tape body after reaching 0m/s only when the length of the energy dissipation flow passage is larger than or equal to that of the energy dissipation flow passage, and the purpose that the escaped carbon dioxide gas is prevented from flowing back into the drip irrigation tape body is achieved.
According to the drip irrigation belt for carbon dioxide water solution irrigation, the minimum width of the flow channel of the Tesla valve-shaped flow channel capable of preventing reverse diffusion is 0.55-1.2mm, the outer tooth tips are distributed in a staggered mode, the distance from the tooth tips of the flow channel teeth to the symmetrical center line of the flow channel is 0-1.09mm, and in the reverse flow blocking of the Tesla valve-shaped flow channel, the effect of reverse flow blocking can be improved by effectively combining the minimum width of the flow channel with the distance from the tooth tips of the flow channel teeth to the symmetrical center line of the flow channel.

The beneficial effects are that:
the utility model changes the existing single wing drip irrigation belt to only have the functions of energy dissipation and pressure reduction, and the water solution entering the flow passage passes through quickly by adding the Tesla valve-shaped flow passage for preventing reverse diffusion, and the carbon dioxide water solution finally slowly drops out of the drip irrigation belt due to the energy dissipation and pressure reduction after entering the energy dissipation flow passage, and the carbon dioxide gas begins to escape and rapidly diffuse in the pressure reduction process. The problems that the water outlet of the tail end emitter is reduced and even water is not available due to the fact that carbon dioxide gas in a carbon dioxide aqueous solution in the energy dissipation and pressure reduction process of the existing drip irrigation belt is diffused into the drip irrigation belt body, and the emitter cannot uniformly drop enough carbon dioxide-containing water into plant root soil, so that the salt inhibition effect is reduced and the yield increasing effect of crops is greatly reduced are solved.
