Mouth pipe, upper tube box shell ring and the fixation angle steel in upper tube box shell ring, connection angle steel, cone, level-one distributing disc, two level
Distributing disc, three-level distributing disc, angle cleat and three-level angle steel；Sulfonic acid inlet tube both sides by multiple fixed angle steel be located at
Centrum below is connected；The upper end center of the centrum is connected by coupling angle steel with sulfonic acid import infratubal port, and above-mentioned
Centrum, fixed angle steel, connection angle steel and sulfonic acid inlet tube lower end constitute two circulating areas；It is equipped in the level-one distributing disc
Storage tank；The centrum is arranged in storage tank；Parallel point above and below the level-one distributing disc, two level distributing disc and three-level distributing disc
Cloth, and be connected by angle cleat between above-mentioned three；Three-level distributing disc lower end both sides pass through three-level angle steel and upper tube box
The inner wall of shell ring is connected；The diameter of the level-one distributing disc, two level distributing disc and three-level distributing disc becomes larger successively, and above-mentioned three
It is provided with several recirculation holes.
Preferably, the quantity of recirculation hole becomes larger successively on the level-one distributing disc, two level distributing disc and three-level distributing disc.
Due to the application of the above technical scheme, the utility model has following advantages compared with prior art：
The falling-film-type distributor of the utility model first passes through two circulating areas before sulfonic acid enters heat exchanger tube
It is flowed into level-one distributing disc, then impacts successively on three distributing discs, reduce flow velocity, it is dead to eliminate layer by layer from new distribution
Area and without liquid zone, enables sulfonic acid to be evenly dispersed on heat exchanger tube, ensures that the overall heat exchange efficiency of heat exchanger tube is high.

Logical region.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
A kind of falling-film-type distributor described in the utility model as illustrated in the accompanying drawings from 1 to 3, including sulfonic acid inlet tube 60, upper tube
Case shell ring 3 and fixation angle steel 61 in upper tube box shell ring 3, connection angle steel cone 62, centrum 40, level-one distributing disc 41,
Two level distributing disc 42, three-level distributing disc 43, angle cleat 44 and three-level angle steel 45；60 both sides of sulfonic acid inlet tube pass through multiple
Fixed angle steel 61 is connected with the centrum 40 being disposed below；The upper end center of the centrum 40 by couple angle steel 62 and sulfonic acid into
Mouth 60 lower port of pipe is connected, and above-mentioned centrum 40, fixed angle steel 61, connection angle steel 62 and 60 lower end of sulfonic acid inlet tube constitute two
A circulating area 80；Storage tank is equipped in the level-one distributing disc 41；The centrum 40 is arranged in storage tank；One fraction
About 43 parallelly distribute on of cloth disk 41, two level distributing disc 42 and three-level distributing disc, and pass through 44 phase of angle cleat between above-mentioned three
Even；43 lower end both sides of the three-level distributing disc are connected by three-level angle steel 44 with the inner wall of upper tube box shell ring 3；The level-one distribution
The diameter of disk 41, two level distributing disc 42 and three-level distributing disc 43 becomes larger successively, and above-mentioned three is provided with several recirculation holes 50.
The quantity of recirculation hole 50 becomes larger successively on the level-one distributing disc 41, two level distributing disc 42 and three-level distributing disc 43,
Sulfonic acid can be made slowly uniformly to be flowed out successively out of recirculation hole, be finally flowed into shell.
When specifically used, sulfonic acid is flowed into out of sulfonic acid inlet tube in falling-film-type distributor, the sulphur in falling-film-type distributor
Acid flows in this way：Circulation persulfonic acid inlet tube first flows into, and is then flowed out by two circulating areas 80, i.e., from centrum
Upper end is flowed out, and can be directly impinging in this way to avoid sulfonic acid on level-one distributing disc, then sulfonic acid is flowed on level-one distributing disc, sulphur
Acid is flowed downstream into from the recirculation hole on level-one distributing disc onto two level distributing disc, and the sulfonic acid that remaining is overflowed is directly from level-one distributing disc
It is dropped on two level distributing disc after the discharge of top, then a sulfonic acid part is flowed into three-level distribution from the recirculation hole of two level distributing disc
In disk, remaining sulfonic acid overflowed is directly flowed into from above two level distributing disc in three-level distributing disc, and last sulfonic acid is distributed from three-level
Recirculation hole in disk is flowed into heat exchanger tube.
The falling-film-type distributor of the utility model first passes through two circulating areas and flows into before sulfonic acid enters heat exchanger tube
Into level-one distributing disc, then impact successively on three distributing discs, reduce flow velocity, layer by layer from new distribution, to deadband eliminating and
Without liquid zone, sulfonic acid is enable to be evenly dispersed on heat exchanger tube, ensures that the overall heat exchange efficiency of heat exchanger tube is high.
The specific application example that the above is only the utility model does not constitute the scope of protection of the utility model any limit
System.Any technical scheme formed by adopting equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
