Abstract
The utility model provides a tube pass medium flow velocity-reducing liquid distributing device. A tube nest is arranged inside a tank; a tube plate is arranged below the tube nest; a liquid distributing device is installed between the tube nest and the tube plate; an inner tube inside the liquid distributing device is sleeved in a heat exchange tube that runs through the tube plate; 4 to 6 arc-shaped plates are welded outside the inner tube of the liquid distributing device; an outer tube with flow-guiding holes is welded outside the arc-shaped plates; a cover plate is welded at top parts of the outer tube with flow-guiding holes, the arc-shaped plates and the inner tube; and a spray nozzle is installed at the center of a face of the cover plate, wherein the cover plate face faces to the inner tube. The liquid distributing devices reduce the flow velocity of liquid flowing into a heat exchange device in a physical manner in order to reduce the scouring and eroding effects exerted by the liquid on the heat exchange device, and vibration of the apparatus as well as the direct washing effects on the tube wall exerted by the fluid can be reduced. Therefore the static electricity occurrence rate can be lowered, and the service life of the heat exchange device can be prolonged.
Description
Technical field
The utility model relates to the chemical industry equipment field, specially refers to a kind of liquid distributor that slows down the tube side velocity of medium.
Background technology
Heat exchanger is the common apparatus of chemical industry, oil, power, food and other a lot of industrial departments, occupies critical role aborning.Present many heat exchangers are to improve velocity in pipes through phase line up flow velocity to reach turbulent flow; Be to be cost with the pressure drop energy loss; And the material high flow rate makes heat exchange original paper wall for a long time in the temperature inversion interval; Receive high flow rate and wash away, then have defectives such as also conventional relatively shell-and-tube heat exchanger weak point of device maintenance clean cycle weak point and life-span.The main heat exchange element of heat exchanger is a heat exchanger tube, and the damage of heat exchanger tube can directly cause the damage of heat exchanger.The main cause that heat exchanger tube damages is the wearing and tearing that should shake generation in erosion and the shell side of tube side fluid with deflection plate.Annual damage because of heat exchanger tube has brought tremendous loss for country and each enterprise.
Summary of the invention
The purpose of the utility model is to provide a kind of liquid distributor that utilizes shower nozzle and pod apertures to slow down the tube side velocity of medium.
For realizing above-mentioned purpose, the technical scheme of the utility model is:
A kind of liquid distributor that slows down the tube side velocity of medium; The outer tube, arc and the interior pipe that comprise card, liquid distributor, tube sheet, cover plate, band pod apertures; Described liquid distributor is equipped with card in jar; Tube sheet is housed below card, between card and the tube sheet liquid distributor is housed, the interior pipe box in the liquid distributor is in passing the heat exchanger tube of tube sheet.
The interior pipe of described liquid distributor is welded with 4-6 piece arc outward, and the outside of arc is welded with the outer tube of band pod apertures, and the top of outer tube, arc and interior pipe of band pod apertures is welded with cover plate, and cover plate is equipped with shower nozzle in the centre towards the one side of interior pipe.
The beneficial effect of the utility model is: this liquid distributor has slowed down the flow velocity in the liquid inflow heat exchanger with the mode of physics; To slow down the erosion of liquid heat exchanging device; Reduce pressure drop; Vibration and the fluid that reduces equipment simultaneously directly washes away tube wall, makes the probability step-down of generation of static electricity, increased the service life of heat exchanger.

Fig. 3, liquid distributor are connected sketch map with liquid line.
The specific embodiment
Further specify the specific embodiment of the utility model below in conjunction with accompanying drawing 1-3.
Referring to Fig. 1, Fig. 2, Fig. 3, liquid is flowed into by the tube side import N1 on tank body top, after card 1 evenly distributes, flows into to be contained in the liquid distributor 2 on the tube sheet 3; In spraying into, the shower nozzle 8 of wherein a part of liquid in the middle of cover plate 4 manage in 7; And flow in the heat exchanger tube 9 through interior pipe 7, another part liquid flows on the tube sheet 3 and gathering from the gap of each liquid distributor 2, when the liquid level of liquid rises to the pod apertures position on the outer tube 5 of being with pod apertures on the liquid distributor 2; The pod apertures of liquid on the outer tube 5 of band pod apertures flows into; And impact on arc 6, in the pipe 7, get at last in the heat exchanger tube 9 in getting into then; Tube side outlet N2 by the tank body bottom flows out, and has therefore slowed down the flow velocity of liquid inflow heat exchanger tube with the mode of physics.
