Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, this utility model embodiment is described in further detail.
As shown in accompanying drawing 1 and accompanying drawing 2, this utility model embodiment provides a kind of swirl jet for catalytic cracking unit, including the bump joint 2 of nozzle body 1, the top water inlet 101 being connected to nozzle body 1.Wherein, nozzle body 1 includes the rotary fluid 102 and the baffle 103 that from top to bottom sequentially connect, and rotary fluid 102 and baffle 103 are coaxially disposed, and rotary fluid 102 is cylindrical, is internally provided with the vortex chamber 1021 rotated vertically; Baffle 103 is in truncated cone-shaped, and inner surface is arc surface, and bottom water jet 104 is circular. Top water inlet 101 is radially arranged along nozzle body 1, and bottom water jet 104 is axially arranged along nozzle body 1.
The swirl jet that this utility model embodiment provides, can be used for catalytic cracking unit, by using bump joint 2 to be connected with cleaning mixture pipeline, first pass through from the cleaning mixture of cleaning mixture pipeline and enter in nozzle body 1 in the vortex chamber 1021 of rotary fluid 102, the swirling motion of high eddy flow degree is carried out around the axis of this nozzle body 1, subsequently enter in baffle 103, and around the circular arc inner surface uniform distribution of baffle 103 under eddy flow inertia force, move downwardly to bottom water jet 104 to spray simultaneously, so it is obtained in that higher spray area, it is effectively improved desulfurization dust-removing efficiency. wherein, by by top water inlet 101 being radially arranged along nozzle body 1, bottom water jet 104 is axially arranged along nozzle body 1, is not only beneficial to cleaning mixture and is smoothed out high-speed rotational motion when entering rotary fluid 102, and is beneficial to the cleaning mixture circular spray area that acquisition is bigger when ejection. additionally, cleaning mixture as above moves in the nozzle that this utility model embodiment provides, moreover it is possible to the cleaning mixture degree of wear to nozzle is greatly lowered. visible, that this utility model embodiment provides swirl jet, can not only obtain bigger spray area, be effectively improved desulfurization dust-removing efficiency, and wear-resistant, long service life, its simple in construction, it is easy to preparation, it is simple to large-scale promotion is applied.
Specifically, as shown in Figure 2, the housing width of vortex chamber 1021 is in axial direction from top to bottom gradually reduced. This carries out description below, and the vortex chamber 1021 arrangement in rotary fluid 102 can be understood as and is similar to compression spring structure, to realize swirling motion. And in order to gradually step up the swirl velocity of cleaning mixture, this utility model embodiment makes the housing width of vortex chamber 1021 in axial direction from top to bottom be gradually reduced, that is is positioned at the housing width housing width less than the vortex chamber 1021 being positioned at above rotary fluid 102 of vortex chamber 1021 below rotary fluid 102.
