CN201006402Y - lobe mixer - Google Patents

Abstract

The utility model relates to a lobe mixer, which is used for mixing the components of two streams of gas, gas and liquid, and the static mixer includes a pipe-shaped shell with two inlets and one outlet. A lobe nozzle mixing element fitted to the housing, inside the housing, with inlet and outlet channels. The utility model can effectively ensure that the two fluids of the primary and secondary flows are fully mixed within a relatively short axial distance, and the total pressure loss is small.

Description

lobe mixer

(1) Technical field

The utility model relates to a compact, high-efficiency and energy-saving wave lobe mixer for mixing components of gas-gas, gas-liquid and liquid-liquid fluids, which belongs to high-efficiency and energy-saving products.

(2) Background technology

In petroleum, chemical, energy, chemical fertilizer and other industries, the mixed application of two media is quite common. At present, the static mixer that uses the principle of mechanical stirring and mixing is mainly used in the industry. The structure is complex, the total pressure loss during the mixing process is large, and the mixing distance is long. The purpose of the utility model is to provide a lobe mixer with small total pressure loss and short mixing distance in the mixing process.

(3) Contents of utility model

The utility model provides a lobe mixer which utilizes the pneumatic principle to fully mix and has a compact structure.

The utility model comprises a pipe-shaped casing with an inlet and outlet, and a lobe nozzle mixing element with an inlet and outlet channel inside the casing whose size is matched to the casing.

The outer shell is located outside the internal components, together with the fluid inlet and the mixture outlet, it forms a closed space with openings at both ends. The size of the closed space, that is, the axial length of the mixing space of the two fluids, is analyzed by numerical simulation and calculation. Sure.

The internal components are composed of circular lobe nozzles of various sizes and types, and the feature of the circular row of lobe nozzles is that various wavy or curved structural surfaces are arranged in a closed circumferential direction, Consists of a closed hollow channel open at both ends.

The internal components are composed of transition sections of various sizes and types. The transition section connects the inlet of the secondary flow and the circular row of wave lobe nozzles. The transition section is characterized by various curved structural surfaces, forming a closed two Open-ended hollow channel.

The internal component is composed of a circular row of lobe nozzles, an outer casing, and a space at the exit section of the mixer. The main flow flows out of the lobe nozzles. Due to the effect of the circulation, the space behind the exit section of the lobe nozzles A strong secondary flow structure is formed in the middle, which greatly enhances the mixing with the secondary flow fluid.

(5) Specific implementation methods

As shown in Figure 1, the lobe mixer is directly connected to the piping system where the two incoming streams are to be mixed. Taking the diesel hydrogenation unit in an oil refinery as an example, the lobe mixer is used as a hot high-separation gas mixer. The main pipe 1 carries the hot high-separation gas, and the central pipe 7 takes the desalination of the amine salt in the heat-absorbing high-separation gas. Water and desalinated water are sprayed into the hot high-separation airflow through the 90° elbow 8, the transition section 9 and the lobe nozzle 10. Because of the effect of the circulation, the injected water and the hot high-separation gas have a short axial distance The internal energy can achieve sufficient mixing, which strengthens the heat and mass transfer effect of the gas-liquid two fluids, and the total pressure loss is small. It is a high-efficiency and energy-saving product.
