Mixing fluids is required and practiced in many industries. Conventionally, there are the following fluid mixing devices and methods provided on a flow path. In a simple structure, the fluids to be mixed are joined together using a T-shaped joint, etc., and a flow path of an appropriate length is provided to mix the fluids. Another method is to mix the fluids by installing an orifice of an appropriate diameter or a solid guide vane on the flow path after the fluids are combined. In addition, an ejector is provided and the first
There is a method in which a second stream of fluid is ejected from a nozzle and a second stream of fluid is absorbed and mixed therewith.

の流速を大きくしすぎると、流体混合装置による
圧力損失が上昇し、混合装置の用途によつては操
作困難になる。 The mixing action of fluids by these fluid mixing devices is caused by turbulence of the fluid itself flowing within the fluid mixing device. Therefore, in order to mix the fluids, it is necessary to increase the flow velocity of the fluid within the mixing device to a certain level or higher in order to cause turbulence in the fluids. However, if the flow rate of the fluid is increased too much, pressure loss through the fluid mixing device increases, making operation of the mixing device difficult depending on the application.

めである。 Therefore, the above-mentioned conventional fluid mixing device is provided with an appropriate structure and size so that the fluid to be mixed has a required flow rate, and is operated within a relatively narrow range of flow rates. That is, in conventional mixing devices, when the flow rate fluctuates over a wide range, an increase in pressure loss is unavoidable. This is because the internal structure of the conventional fluid mixing device is fixed and cannot be easily changed in response to fluctuations in fluid flow rate.

ている。 Next, the principle of the present invention will be explained. When a freely movable floating body of an appropriate shape, size, and density is housed in a tapered tube installed almost vertically with the small diameter side facing down, and fluid is supplied from below, the floating body will react to the pressure difference that occurs before and after it. However, as the floating body moves upward, the area of communication between the floating body and the tapered tube increases, so the velocity of the fluid passing through it decreases and the pressure difference decreases, and the floating body It comes to rest at a position where its own weight and the force due to the pressure difference are balanced. In other words, in a device in which a floating body is housed in a tapered pipe, even if the amount of fluid supplied increases, the floating body automatically changes its resting position within the tapered pipe according to the flow rate, and pressure loss does not increase. Are known. On the other hand, it is known that when a stationary object is placed in a fluid, eddies occur behind the object. Accordingly, when the floating body is in a stationary state due to the fluid supplied into the tapered pipe, eddies are generated behind the floating body.

するにある。 Next, specific application examples of the present invention will be described. FIG. 7, previously filed as Japanese Patent Application No. 58-11287, is an immobilized enzyme reaction device in which a reaction solution is passed through and enzyme reactions are carried out continuously. The immobilized enzyme reaction apparatus includes a reactor 20, a raw material storage tank 21, a raw material pump 22, a reaction liquid storage tank 23, a PH adjustment liquid storage tank 24, and a pump 25. This reactor 2
The structure of No. 0 is a multi-stage packed bed type in which reaction vessels 26 and adjustment sections 27 are arranged alternately in multiple stages. The purpose of the present invention is to provide an immobilized enzyme reactor that can be adjusted to an optimum range and has higher reaction efficiency.

A function to mix the PH adjustment liquid and the reacted liquid is required. Furthermore, since the compressive strength of the immobilized enzyme particles packed into the reaction bed is generally small, pressure loss is required to be as low as possible. Incidentally, the activity of the immobilized enzyme gradually decreases with the passage of reaction time. Therefore, in order to keep the reaction rate of the reaction liquid in the reactor 20 constant, the flow rate of the reacted liquid supplied to the reactor 20 is gradually reduced in accordance with the decrease in the activity of the immobilized enzyme. Therefore, in the adjustment section 27, good mixing accuracy can be obtained in response to the variation range of the supply flow rate of the reacted liquid,
In addition, the ability to operate with low pressure loss is required.

On the other hand, since the fluid mixing device of the present invention shown in FIG. 1 can satisfy all of these required functions, if it is applied to the adjustment section 27, the immobilized enzyme reactor can be operated efficiently.

Additionally, porous plates 8 are provided at the upper and lower portions of the tapered tube 2 to prevent the floating bodies 3 from flowing out. Further, an inlet 5 for the pH adjustment liquid is provided at the lower part of the tapered tube 2, and opens approximately at the center of the tapered tube 2. Further, the outside of the tapered tube 2 is a jacket, and pipes 28 and 29 for supplying and discharging cooling water are provided outside the adjustment section 27.

てもよい。 Next, a modification will be explained. In addition to the spherical shape shown in Figure 1, the shape of the floating body 3 may be one in which the upper part is a disk shape and the lower part is a cone shape (Figure 9), or one in which the upper disk is diagonally shaped. A groove is cut in the shape of the tapered pipe so that it can be rotated by the fluid in the pipe (Fig. 10), and a disc with two discs spaced apart
It is also possible to have a shape with more than one layer (Fig. 11).

用する横型の流体混合装置を構成してもよい。 In addition, by expanding the principle of a fluid mixing device in which a freely movable floating body is placed inside a tapered pipe, floating bodies with a specific gravity that is lighter than the fluid can be stored in a tapered pipe that widens at the bottom, and the fluid is allowed to flow from the top. A method (not shown) may also be used. Furthermore, as shown in FIG. 12, the floating body may be housed in a tapered tube together with an elastic body 30 such as a spring, and a horizontal fluid mixing device may be constructed that utilizes the repulsive force of the elastic body.

According to the present invention, even if the supply flow rate increases, the floating body automatically changes its resting position in the tapered pipe according to each flow rate, and the fluid is mixed by the eddies generated behind the floating body, and the pressure is increased. Since the loss does not increase, the device of the present invention can respond to a wide range of flow rate fluctuations of the fluids to be mixed, achieve good mixing accuracy, and operate with low pressure drop.
