Embodiment Construction

[0009] The high-speed and high-pressure spiral nozzle of the present invention is realized in this way, which will be described in detail below in conjunction with the accompanying drawings. See figure 1 The high-speed and high-pressure spiral nozzle of the present invention is composed of a shell 1 and a core 2. The shell 1 is in the shape of a water cup, and the outer contour is an octagonal polygon, which can increase the rigidity of the shell. The whole is divided into a threaded section 3 and a transition section 4. , contraction section 5, throat 6 and diffusion section 7; the large end in the cup hole has an internal thread as the threaded section 3, which is connected with the liquid delivery pipe joint through threads; the surface of the mating section 4 is a round hole and a core The outer circles of 2 are matched to ensure that the shell 1 and the core 2 are coaxial, and are made of stainless steel casting; The liquid flow generated by the rotation is continuously ...

Abstract

The invention relates to a high-speed high-pressure spiral nozzle, which is characterized in that the nozzle consists of a shell and a core body; the nozzle is made of stainless steel through cast forming; the shell is in a water-glass shape; the external contour of the shell is a round or eight-angle polygonal body; the whole shell is divided into a thread section, a transition section, a contraction section, a throat channel and a diffusion section; a big end provided with an inner thread in a glass hole is the thread section; the surface of the transition section is a round hole matched with the outer circle of the core body; the contraction section is a conical hole; the upper end of the throat channel is in arc transition connection with the lower end of the contraction section; the diffusion section is positioned in an outlet of the throat channel and is in a bellmouth shape; the middle of the core body is provided with a vertical plate; and two sides of the core body are provided with double-line spiral blades connected with the transition section of the shell through the vertical plate of the core body. The high-speed high-pressure spiral nozzle has the characteristics of low spray-body energy loss, large spray amount, stable uniform spray area and insusceptibility to blockage. The nozzle is made of stainless steel and has the advantages of wear resistance, corrosion resistance, long life span and wide application range.

Description

technical field [0001] The invention relates to a high-speed and high-pressure spiral nozzle used for spraying washing liquid in absorption towers, washing towers and purification towers in metallurgical coking, petrochemical and other industries. Background technique [0002] At present, there are two types of nozzles for spraying washing liquid in absorption towers, washing towers, and purification towers traditionally used in metallurgical coking, petrochemical and other industries in China, one is atomizing nozzles, and the other is used for metallurgical coking, petrochemical Under the action of pressure, the washing liquid is sprayed out at a high speed to achieve the purpose of absorbing the chemical components in the gas and washing. This kind of nozzle has disadvantages such as complex design structure, difficult manufacturing and processing, large resistance to liquid, high energy consumption, and easy clogging, which limits the scope of use.
