Description
Technical field
The present invention relates to the filming device in a kind of pipe heat exchanger.
Background technology
Pipe heat exchanger is a kind of heat transmission equipment commonly used in the process for making alumina, the height of pipe heat exchanger heat exchange efficiency depends on the distribution situation of liquid film to a great extent, as if one deck liquid film that can both evenly distribute on the inwall that makes heat exchanger tube, then heat exchange efficiency will be greatly improved, it is opposite if liquid film distributes very inhomogeneous, then can form full packages (being to have filled with feed liquid in the heat exchanger tube) in the heat exchanger tube, main phenomenons such as (no feed liquids in the heat exchanger tube), not only heat exchange effect of these two kinds of phenomenons is very bad and can cause the local stress of heat exchanger tube very big, the exchange heat pipe, have a significant impact the service life of tube sheet and heat exchanger.
Summary of the invention
The technical problem to be solved in the present invention is: the filming device in a kind of pipe heat exchanger is provided, its characteristics be simple in structure, can regulate the feed liquid circulation area, the cloth film is effective, quality of forming film is high, in use can obtain good heat exchange effect, to overcome the deficiency that prior art exists.
Technical scheme of the present invention is as follows: layered material pond under installing above the tube sheet of pipe heat exchanger, above following layered material pond, the upper layer material pond is installed, and blanking channel in the middle of being provided with in the centre in upper layer material pond, on following layered material pond several being installed there is cloth film head.
Cloth film head is made up of steel cylinder, gusset, steel pipe, plug, and steel pipe is connected with steel cylinder by gusset, and steel pipe is connected with plug.
Steel pipe and plug be by being threaded, thereby the gap between steel pipe lower surface and the plug circular-arc-shaped exterior contour can be regulated.Can reach the effect of the flow of the material of regulating steel pipe by the distance of regulating between the two, thereby make this cloth film head can satisfy the cloth film needs of various flows in the certain limit greatly
The top of passing steel pipe at plug also is equipped with locking nut.
Whole filming device divides upper and lower two layered material ponds, and a blanking channel is arranged in the middle of the upper layer material pond.Many cloth film heads have been hung on the following layered material pond in order to the distribution feed liquid.Its cloth pleurodiaphragmatic in terspace reason is as described below: when material when the liquor inlet of filming device top enters filming device, this moment, the flow velocity of material was very fast, material will bump with the base plate in upper layer material pond, so material will gush at upper layer material pond turning in, and some material can flow to down the layered material pond from middle blanking channel.The flow velocity of material slows down in the upper layer material pond at this moment, but still being to turn over dynamically gushes.Because the circulation area of the blanking channel in upper layer material pond is far smaller than the circulation area of feed pipe, so have only the small part material to flow to down the layered material pond by the blanking channel in upper layer material pond, and most of material still accumulates in the upper layer material pond.And amass after the full with substance in the upper layer material pond by the time, material will be from the outer wall overflow in upper layer material pond and is gone out, flow to down the layered material pond, this moment, the charging and discharging amount in upper layer material pond reached balance (promptly the material that flows to the upper layer material pond from charging aperture all flows to down the layered material pond by the upper layer material pond), and the flow velocity of material greatly slows down.Following layered material pond has been owing to just just accepted the material that blanking channel flows down in the middle of the upper layer material pond when having begun, and this part material has been umbrella by cloth film head and is distributed to equably on the tube sheet, so do not have buildup in the layered material pond this moment down.Along with the material in upper layer material pond continues to flow down,, and finally can amass full with substance so the layered material pond also begins buildup as the upper layer material pond down.At this moment, the material in the following layered material pond also separated into two parts flows on the tube sheet, and a part is to flow on the tube sheet by cloth film head, and another part then overflows on the tube sheet from the outer wall in following layered material pond, and this moment, the flow velocity of material obtained further slowing down.Because the termination of heat exchanger tube will exceed a segment distance than tube sheet upper surface, so the material on the tube sheet can slowly be assembled, when the gathering height was concordant with the heat exchanger tube termination by the time, material will overflow in the heat exchanger tube equably along the heat exchanger tube inwall, and formed the uniform one deck liquid film of thickness in heat exchanger tube.Because material temperature is more much lower than the temperature of the outer steam of heat exchanger tube, so steam can be by heat exchanger tube the heat transferred material, and the evaporation that material will be a large amount of after being heated.
Compared with prior art, filming device of the present invention can be with material gently, be distributed on the tube sheet equably, and feed liquid can be overflowed on the inside pipe wall of heat exchanger tube equably form the layer of even liquid film, makes the heat exchange better effects if, and heat exchange efficiency is higher.Prolong the service life of tube sheet, heat exchanger tube and heat exchanger simultaneously, improved production efficiency and economic benefit.

The specific embodiment
Embodiments of the invention: layered material pond 8 under installing above the tube sheet of pipe heat exchanger, above following layered material pond 8, install layered material pond 6, blanking channel 7 in the middle of being provided with in the centre in upper layer material pond 6 is being installed several cloth film heads 9 on the layered material pond 8 down.
Gusset 2 plays the fixedly effect of steel pipe 3, and steel pipe has been attacked internal thread, for the usefulness of regulating gap between steel cylinder 1 and the plug 4, reaches the flow velocity of adjusting umbrella cover shape liquid film and the effect of flow whereby.5 of locking nuts are to play the locking plug, prevent that plug is loosening and influence cloth film effect under the continuous impact of feed liquid.Plug is a hollow, and exterior contour is circular-arc and straight bar part has been attacked externally threaded revolution steel part.Because plug adopts and is threaded, so the outline of plug and the distance between the steel pipe lower surface are adjustable, and can reach the effect of the flow of the material of regulating steel pipe by the distance of regulating between the two, thereby make this cloth film head can satisfy the cloth film needs of various flows in the certain limit greatly.And the special construction of cloth film head can make material possess certain speed and be the umbrella cover shape to evenly distributing all around under the effect of certain fluid column static pressure.Circular hole passage in the middle of the plug then is the cloth film blind area that stays in order to fill up liquid film to distribute liquid film around plug, and the liquid film that makes the zone under the plug also have feed liquid to form plays the effect of the liquid film that more evenly distributes.Should be noted that a bit: because plug and steel cylinder cause wearing and tearing easily with contacting of feed liquid in the cloth film head, so whole cloth film head preferably uses the high-abrasive material making.
