Description
Technical field:
The present invention relates to a kind of shell-and-tube heat exchanger that is used for, reduce the liquid guide flow plate of heat exchanger tube condensed exterior thickness of liquid film.
Background technology:
Condensing heat exchanger is widely used in fields such as oil, chemical industry, metallurgy, pharmacy, air-conditioning, refrigeration and heat supply, and the height of its heat exchange efficiency directly affects industrial production cost and efficiency of energy utilization, so it is important research always and improves object.Since the seventies in last century, at how improving condensing heat exchanger heat exchange property problem, people have obtained a large amount of fruitful achievements by changing the tube outer surface architectural characteristic.Yet these work do not solve in the tube bank of horizontal condensing heat-exchange equipment level and go up following of comb condensate liquid, cause that row's condenser pipe liquid film increases the back and causes the heat exchange property decline problem of (be called and restrain effect) down.When horizontally disposed condensing heat-exchange equipment was restrained in the design condensation, people can only rely on the quantity that increases heat exchanger tube to compensate the adverse effect of tube bank effect heat exchanging, thereby cause the increase of heat transmission equipment volume and the raising of manufacturing cost at present.Therefore, people seek a kind of technical measures that can reduce condenser pipe condensed exterior thickness of liquid film, reduction out-tubular condensing liquid film thermal resistance, improve condensing heat-exchange efficient always.
Summary of the invention:
The purpose of this invention is to provide a kind of condensation tube drainage device that can reduce out-tubular condensing thickness of liquid film, reduction liquid film thermal resistance, improve condensing heat-exchange efficient.
Above-mentioned purpose is achieved through the following technical solutions
Condensation tube drainage device is characterized in that: intake chute is housed below heat exchanger tube, and described intake chute is the spill that has curved surface or inclined-plane composition.
Described condensation tube drainage device, described intake chute section configuration is curved surface or inclined-plane.
Described condensation tube drainage device, described curved surface are single circular arc or Gothic or ellipse, and described inclined-plane is single plate shaped or two plate shaped.
Described condensation tube drainage device, described intake chute has projection along the condensation section length direction.
Described condensation tube drainage device, the drainage plate on described intake chute top are zigzag, wing shape, linear barrier shape.
This technical scheme has following beneficial effect:
1. the present invention is fixed on drainage plate and intake chute by jump ring the bottom of condenser pipe, drainage plate closely contacts with condenser pipe, condensate liquid flows on the drainage plate outside condenser pipe under gravity and capillary effect, and flow in the intake chute, liquid in the last intake chute is directed to the condenser pipe two ends, avoided the condensing droplet of last layer condenser pipe to fall down on one deck condenser pipe, thereby avoided the increase of time one deck condenser pipe liquid film, had the effect of eliminating the tube bank effect, realizing the outer enforcing condensation heat exchange of condenser pipe.
2. drainage plate of the present invention plays the effect that reduces condenser pipe thickness of liquid film and drainage, and intake chute then plays the effect that stops condensing droplet to fall down row's condenser pipe and condensate liquid is derived.
3. the present invention is first in application penetrates condenser pipe in the gripper shoe of condenser pipe, with several jump rings and pin intake chute and drainage plate is being fixed on outside the condenser pipe then, and the application of jump ring makes the installation of drainage device become simply, make things convenient for.
4. condensation tube drainage device of the present invention both can the condenser pipe of smooth outer surface on, also can be used in appearance is on the high-efficiency condensation pipe of low rib.
5. by jump ring intake chute is fixed on the condenser pipe, steam is being equipped with on the condenser pipe of drainage device after the condensation, and the condensate liquid of formation compiles to duct bottom along the condenser pipe outer surface, forms thicker liquid film in duct bottom.Liquid film is pooled in the intake chute under the drainage of drainage plate, and flows away along intake chute.Said process has avoided last row's condensate liquid directly to drop onto down the comb bundle, avoided the increase of time discharge pipe outer surface thickness of liquid film, avoided the increase of time discharge pipe outer surface liquid film thermal resistance, thereby improved the heat exchange efficiency of condensing heat-exchange equipment, reduce equipment volume, reduce the consumption of condenser heat exchange tube material.Therefore, the present invention can be widely used in the various horizontal out-tubular condensing heat transmission equipment in the fields such as oil, chemical industry, metallurgy, pharmacy, air-conditioning, refrigeration and heat supply.
By drainage plate to the drainage of condenser pipe condensed exterior liquid film and intake chute drain to condensate liquid, can reduce the thickness of condenser pipe condensed exterior liquid film, reduce out-tubular condensing liquid film thermal resistance, improve the heat exchange efficiency of condenser pipe.
7. effective vertical height of the intake chute of different curve shape and drain amount difference, the variation of curved surface form is that the diversity of curve form makes intake chute that the application space of wider model arranged to the multifarious a kind of adaptation of condenser pipe tube pitch and condensing liquid quantity in the practical application.
