Description
Technical field
The present invention relates to a kind of chemical industry equipment, the heat exchanger of using always in especially a kind of chemical process that evaporates, specifically a kind of high-efficiency evaporator.
Background technology
As everyone knows, evaporimeter is a kind of common chemical industry equipment, and it is mainly used in the chemical reaction heats mixed liquid medium, thereby makes low-boiling medium evaporate separation from blending agent.
Traditional evaporimeter mainly is made up of heat exchanger tube, and mixed liquid medium directly enters the heat pipe from charging aperture and carries out heat exchange with the heat pipe heat-conducting medium on every side of flowing through, thereby reaches the mixed liquid medium heating.Because the medium that enters heat pipe from charging aperture is to flow directly into the heat pipe, has been full of medium in the heat exchanger tube, and real heat exchange efficiency high be in the pipe along around the medium of tube wall, near the medium of tube hub, heat exchange efficiency is low more.And owing to be full of liquid medium in the heat exchanger tube, separate, influence the raising of evaporation efficiency and make the lower boiling gas phase media that produces in the heat transfer process be difficult for evaporation, this structure is very unfavorable for the efficient that improves evaporimeter.
Summary of the invention
The objective of the invention is rationally to cause the not high problem of heat exchange efficiency inadequately, design a kind of high-efficiency evaporator that can effectively improve heat exchange efficiency at existing evaporation structure design.
Technical scheme of the present invention is:
A kind of high-efficiency evaporator comprises heat exchanger tube 1, and heat exchanger tube 1 is installed in the heat exchanging chamber 2, the upper end of heat exchanger tube 1 is fixed on the upper perforated plate 3, the top that it is characterized in that described upper perforated plate 3 is equipped with distribution grid 4, and distributor pipe 5 is installed on the distribution grid 4, and every distributor pipe 5 aligns one by one with heat exchanger tube 1 center.On distribution grid 4, every distributor pipe 5 around be equipped with spout hole 6, the projection of this spout hole 6 should be positioned at heat exchanger tube 1 on the upper perforated plate 3 around, after guaranteeing that mixed liquid medium flows out from spout hole 6, flow on heat exchanger tube 1 upper perforated plate 3 end faces on every side, around heat exchanger tube 1 inwall, flow down then, reach sufficient heat exchange evaporation effect; Described distributor pipe 5 covers are contained in cover plate 8 times, semicanal 7 suspends and is fixed on cover plate 8 times and the lower end of semicanal 7 is lower than the upper end of distributor pipe 5, cover plate 8 is fixed in the feed cavity 12, cover plate 8 is provided with the adapter 9 that communicates with semicanal 7 inner chambers, take over 9 upper end and be not less than the charging aperture of installing on the feed cavity 12 10, on cover plate 8, be provided with for the feed opening 11 of the material flow in the charging aperture 10 to the distribution grid 4.
Described feed opening 11 is positioned at the edge of cover plate 4 and is semicircle shape, and its quantity is at least two and symmetrical distribution.
Described distributor pipe 5 is equilateral triangle and distributes, described spout hole 6 be distributed on distributor pipe 5 around.
Beneficial effect of the present invention:
The present invention is by leading to the medium that enters in the heat exchanger tube, make it to enter in the heat exchanger tube along the heat exchanger tube tube wall, utilize the tube wall and the thermal medium of the heat exchange pipe external surface of flowing through to carry out sufficient heat exchange, the gas that is evaporated in the heat pipe separates rising smoothly, so evaporation effect is improved fairly obvious.
The present invention is simple in structure, and is easily manufactured, the cost performance height.

The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Shown in Fig. 1-6.
A kind of high-efficiency evaporator, its overall structure as shown in Figure 6, it comprises the heat exchanger tube 1 that is installed in the housing, and heat exchanger tube 1 is installed in the heat exchanging chamber 2 of lower house composition, and the upper end of heat exchanger tube 1 is fixed on the upper perforated plate 3, the top of described upper perforated plate 3 is equipped with distribution grid 4, distributor pipe 5 is installed on the distribution grid 4, as shown in Figure 1, on distribution grid 4, every distributor pipe 5 around be equipped with spout hole 6, shown in Fig. 2,3, the projection of this spout hole 6 should be positioned at heat exchanger tube 1 on the upper perforated plate 3 around; Described distributor pipe 5 covers are contained in cover plate 8 times, semicanal 7 suspends and is fixed on cover plate 8 times and the lower end of semicanal 7 is lower than the upper end of distributor pipe 5, cover plate 8 is fixed in the feed cavity 12, cover plate 8 is provided with the adapter 9 that communicates with semicanal 7 inner chambers, as shown in Figure 4, the upper end of adapter 9 is not less than the charging aperture of installing on the feed cavity 12 10, as shown in Figure 1, on cover plate 8, be provided with for the feed opening 11 of the material flow in the charging aperture 10 to the distribution grid 4, as shown in Figure 5.During concrete enforcement, feed opening 11 can be positioned at the edge of cover plate 4 and be semicircle shape, and as shown in Figure 5, its quantity is at least two and symmetrical distribution.Distributor pipe 5 preferably is equilateral triangle and distributes, spout hole 6 be distributed on distributor pipe 5 around (shown in Figure 3).
Liquid medium enters from charging aperture 10 and falls on the cover plate 8 feed cavity 12, and flow on the distribution grid 4 along the feed opening 11 at cover plate 8 edges, because distributor pipe 5 exceeds the lower end of feed opening 11, therefore medium can only fall on the upper perforated plate 3 at spout hole 6 mobile on the distribution grid 4 and from distribution grid 4, because the drop point of the medium that spout hole 6 flows down is around the pore of the heat exchanger tube on the upper perforated plate 31, therefore the medium that falls on the upper perforated plate 3 will inevitably flow on upper perforated plate 3, tube wall along heat exchanger tube 1 flows downward then, the thermal medium outer with tube wall carries out sufficient heat exchange, the low-boiling gaseous medium that produces in heat exchanging process then rises and enters in the feed cavity 12 through distributor pipe 5 and adapter 9 from the center of heat exchanger tube 1, discharges evaporimeter by corresponding exhaust apparatus at last.
The charging of the structure of part that the present invention does not relate to such as heat exchanger tube, mounting means and evaporimeter bottom, drawing mechanism are all identical with existing evaporimeter maybe can to adopt prior art to be realized.
