Embodiment Construction
[0022] see figure 1 , figure 2 with image 3 , The basic structure of the mixer is a horizontal barrel-shaped mixing barrel with closed ends, designed with two nozzles 2 and 3, a circular liquid inlet 4 and a circular low-pressure liquid outlet 5. The two nozzles adopt a reasonable space arrangement, the two nozzles spray fluid A, the circular liquid inlet enters fluid B, and the mixed liquid is discharged from the circular low-pressure liquid outlet.
[0023] Specifically, the first nozzle 2 is located in the upper right corner of the recumbent drum, and the outlet flow path of the nozzle is tangent to the inner wall of the drum; the second nozzle 3 is located in the lower left corner of the recumbent drum, and the nozzle outlet flow path is tangent to the inner wall of the drum. cut. or, see Figure 4 , the first nozzle 2 is located in the lower right corner of the recumbent drum, the nozzle outlet flow path is tangent to the inner wall of the drum, the second nozzle 3 ...

The invention relates to a horizontal double-nozzle liquid static-mixer which comprises a horizontal mixing barrel. The barrel is provided with two nozzles, a liquid inlet and a liquid outlet; the nozzles are located at opposite two diagonal positions close to the two ends of the mixing barrel, and an outlet runner of each nozzle is tangential to the internal wall face of the mixing barrel, so that fluids respectively tangentially enter in the mixing barrel from the two ends of the mixing barrel, and rotate under the guidance of the wall face of the mixing barrel so as to form two rotating flows which are opposite in rotating direction along the internal wall face of the mixing barrel. The liquid inlet and the liquid outlet are circular, and are designed in the middle of the mixing barrel, a connecting line between the circle center of the liquid inlet and the circle center of the liquid outlet is a diameter line located in a circular barrel cross-section at 1 / 2 of the length of the mixing barrel; and fluids entering the mixing barrel from the two nozzles carry out extrusion and shear mixing actions on a fluid entering the mixing barrel from the liquid inlet from the left and right sides, and finally, three fluids entering the mixing barrel are converged and then flow out of a low-pressure outlet, so that a mixed fluid mixed well can be obtained. The static-mixer disclosed by the invention can be used for uniformly mixing drilling fluids and rapidly mixing two drilling fluids or rapidly mixing a drilling fluid with water in petroleum engineering, and also can be applied to the fluid mixing processes in chemical, environmental protection, medicine, food industries and the like.
Description
technical field [0001] The invention relates to a horizontal double-nozzle liquid static mixer, which is used for uniform mixing of drilling fluid in petroleum engineering, rapid mixing of two drilling fluids or drilling fluid and water, and is also suitable for industries such as chemical industry, environmental protection, medicine, and food. fluid mixing process. Background technique [0002] In oil and gas drilling engineering, a large amount of drilling fluid is applied. Drilling fluid components are complex, and the density and viscosity change within a certain range. Industrial applications require continuous mixing with large displacement and high efficiency. Drilling fluid mixing technology has experienced jet gun mixing, circulating mixing, and mechanical agitator mixing. At present, it is the mechanical agitator mixing method that is widely used, and the mixing uniformity is not very good. Static mixer mixing drilling fluid technology originated in the United St...
