Embodiment Construction
[0022] see figure 1 , the mixer includes an upright barrel-shaped cylinder 1, and a low-pressure outlet 2 and three inflow nozzles are arranged on the peripheral wall of the cylinder, which are respectively the upper inflow nozzle 3, the lower inflow nozzle 4, and the middle inflow nozzle 5.
[0023] see figure 2 , three inflow nozzles viewed from the horizontal projection, the horizontal projections of the two inflow nozzles at the low and high positions coincide, while the horizontal projections of the inflow nozzles at the middle position and the two inflow nozzles at the low and high positions are in the form of a barrel A diameter line D1 of the cylinder is arranged symmetrically to the axis of symmetry, and the outlet centers of the inflow nozzles on both sides intersect with the inner wall of the barrel. The angle α between the axis of the inflow nozzle and the line connecting the center of the nozzle outlet on both sides and the inner wall of the barrel is equal to ...

A vertical three-nozzle liquid static mixer comprises an erect cylindrical barrel body. The circumferential wall of the barrel body is provided with three inlet nozzles and a low-pressure outlet; and installation angle of elevation of the inlet nozzle at a low position, a middle position and a high position are respectively beta 3, beta 2 and beta 1, which satisfy the relation of: beta 3>beta 2>beta 1. Seen from the horizontal projection of the cylinder, horizontal projection of the two inlet nozzles at the low position and the high position coincide; the horizontal projection of the inlet nozzle at the middle position and the horizontal projection of the two inlet nozzles at the low position and the high position are symmetrical by an axis of symmetry which is a diameter line D1 of the cylinder; centers of the outlets of the inlet nozzles at both sides of the diameter line intersect with the inner wall of the cylinder; a ligature of the points of intersection of centers of nozzle outlets with the inner wall of the cylinder is a diameter line D2 of the cylinder; and included angles alpha of the axes of the low, middle and high three inlet nozzles with the diameter line D2 of the cylinder are equal, so that jet flows intersect and spray to the cylinder wall. The mixer has advantages of high shear rate, large mixed flow and instant mixing and usage.
Description
technical field [0001] The invention relates to a vertical three-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 State...
