Abstract
The utility model discloses a liquid distributor for a horizontal tube falling film evaporator. The lower part of a central tube is communicated with a distributing tube; a row of liquid distributing tubes is communicated with the lower part of the distributing tube; and slots are formed at the lower ends of the liquid distributing tubes; each slot is in the shape with narrow middle part and wide two ends. The liquid distributor has high liquid distribution uniformity, and the middle part and the two sides of each slot can be designed according to different feed liquid, so that the liquid distributor has higher applicability and can be applied to wider applicable scope. The liquid distributor is suitable for various types of feed liquid such as thermo sensitive feed liquid, sticky feed liquid, granular feed liquid and the like, thereby reducing the bifurcation and the splash of the feed liquid and ensuring relatively uniform film distribution.
Description
Technical field
The utility model relates to a kind of chemical industry equipment, especially a kind of horizontal pipe falling film evaporation device liquid distributor.
Background technology
In the operation of horizontal pipe falling film evaporation device, feed liquid is evaporation outside pipe, and molten in order to make (material) liquid evenly distributes along heating tube, and makes molten (material) liquid effective cloth film on the heating tube length direction, need add liquid distribution apparatus (liquid distributor) above heating tube bundle.The structure of liquid distribution device directly influences distribution of liquid and film forming quality, and liquid distribution device is one of critical component of horizontal pipe falling film evaporation device.Many workers both domestic and external have done a large amount of deep researchs to falling film evaporation, but the overwhelming majority is the research to the Heat Transfer in Evaporating Falling Film performance, for the research of liquid distribution comparatively speaking then seldom.Distribution apparatus commonly used has tangential cellular type, tangential slot type, slotted disc type, calandria etc.These liquid distribution troughs respectively have pluses and minuses, and the uniformity in the size of perforate, the width of groove, quantity and cloth hole all directly has influence on the distribution of liquid situation.Various liquid distributors have the own different scope of application, and significant limitation is arranged.And the performance of liquid distributor needs to verify that with a large amount of test datas requirement on machining accuracy is higher.
The utility model content
The technical problems to be solved in the utility model provides a kind of horizontal pipe falling film evaporation device liquid distributor of applied range.
For solving the problems of the technologies described above, the utility model is communicated with distributing pipe by the central tube bottom, is communicated with row's liquid distributor in the distributing pipe bottom, has the groove crack in the lower end of liquid distributor, and described groove crack is narrow in the middle of being, the shape that two ends are wide.
The relative arcuate shape that groove described in the utility model crack is preferably gradually wide from the middle to both ends is so that feed liquid is assigned with is more even.
Adopt the beneficial effect that technique scheme produced to be: feed liquid in the utility model liquid distributor by the centre in the assigning process of both sides, middle slit is narrower, the slit broad on both sides, follow the increase of material resistance drop in flow process, the relative of resistance drop reduces when descending in wide slit with feed liquid, resistance drop is able to balance, has improved the uniformity that material distributes effectively.The utility model adopts groove crack cloth liquid, and material is behind cloth film from the ground floor heat exchanger tube, and when flowing to one deck heat exchanger tube, feed liquid bifurcated and splash phenomena reduce, and the cloth film is even relatively.The utility model cloth liquid uniformity height, and can design the centre and the both sides in slit according to different feed liquids, make it to have higher applicability, be applied to the scope of application of broad.The utility model can adapt to the feed liquid than polytype, as thermal sensitivity feed liquid, viscosity feed liquid, graininess feed liquid etc.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;

The specific embodiment
As shown in Figure 1, 2, this horizontal pipe falling film evaporation device liquid distributor is to be communicated with distributing pipe 1 in the bottom of central tube 2, be communicated with 5 liquid distributors 3 in distributing pipe 1 bottom, the quantity of liquid distributor 3 can be arranged according to the needs of applied horizontal pipe falling film evaporation device, is used to control the cloth liquid speed of liquid distributor.
As shown in Figure 3, the lower end of the liquid distributor 3 of this liquid distributor has groove crack 4, and groove crack 4 is narrow in the middle of being, the shape that two ends are wide, and it is evenly excessive to be circular arc from the middle to both ends.For adapting to different materials, the width of 4 two ends, groove crack and centre is than being designed to different ratios: for viscous material, the width of 4 ends, groove crack is 3-5 a times of intermediate width; To granular material, particle grain size has determined that the intermediate width in groove crack 4 is a minimum widith, and the width of end is 2-3 a times of minimum widith.
Fig. 4 has provided the upward view of the another kind of embodiment of this liquid distributor, wherein the groove crack 4 of liquid distributor 3 is to the gradually wide middle straight line in both sides, two terminal circle arc shape from the centre, 4 two ends, groove crack are designed according to different feed liquids with middle width ratio, for the viscosity feed liquid, the width of 4 ends, groove crack is 3-5 a times of intermediate width; To the graininess feed liquid, particle grain size has determined that the intermediate width in groove crack 4 is a minimum widith, and the width of end is 2-3 a times of minimum widith.
Fig. 5 has provided the upward view of another embodiment of this liquid distributor, wherein the groove crack 4 of liquid distributor 3 is from the middle to both ends linearly evenly excessively, 4 two ends, groove crack are designed according to different feed liquids with middle width ratio, for the viscosity feed liquid, the width of 4 ends, groove crack is 3-5 a times of intermediate width; To the graininess feed liquid, particle grain size has determined that the intermediate width in groove crack 4 is a minimum widith, and the width of end is 2-3 a times of minimum widith.
