Detailed description of the invention
As it can be seen, a kind of shell-and-tube cooler with distribution device, including cylindrical housings 5, it is arranged on cylinder The end socket 3 of housing 5 upper end and the storage tank 9 being sealedly connected on cylindrical housings 5 lower end, cylindrical housings 5 and end socket 3 and storage tank 9 Between all use Flange joint.Upper and lower end within cylindrical housings 5 is correspondingly provided with upper perforated plate and lower perforated plate, two tube sheets it Between be provided with the heat-exchanging tube bundle being made up of the many heat exchanger tubes be arrangeding in parallel 6, two tube sheets by the inner space of condenser from upper and Under be divided into cloth air chamber 4,10 3 chambers of heat exchanging chamber 7 and liquid collecting room, be delivered to cloth air chamber 4 gas enter each heat exchanger tube 6 also Carrying out heat exchange with the coolant in cylindrical housings 5 in heat exchanging chamber 7 and condense, the condensed fluid in each heat exchanger tube 6 flows into described Liquid collecting room 10.The top of described cloth air chamber 4 is provided with air inlet 1, and the bottom of cylindrical housings 5 and top are respectively equipped with coolant and enter Mouth 8 and cooling liquid outlet 13, the bottom of liquid collecting room 10 and top are respectively equipped with leakage fluid dram 11 and air vent 12.Use in condenser Water-cooling pattern condenses, and gas inlet pipe journey is from up to down moved, and cooling water enters the bottom-up motion of shell side, and both are countercurrently carried out Heat exchange, effectively makes the gas in pipe condense, and is collected in storage tank 9, i.e. in liquid collecting room 10, by arrange bottom liquid collecting room 10 Leakage fluid dram 11 discharges.
In order to make the gas energy uniform distribution in entrance cloth air chamber 4 enter in each heat exchanger tube 6 to condense, this practicality is newly Type is embodied as follows: described air inlet 1 includes an air inlet pipe, and air inlet pipe stretches into the one end in cloth air chamber 4, and to connect one horn-like Enlarging valve 17, in cloth air chamber 4, the body portion of air inlet pipe connects a distribution device 2, and distribution device 2 is by the cover of hemisphere face shape Body 18 and be sealedly connected on the curved slab 20 bottom cover body 18 and form, the central area of curved slab 20 raises up, enlarging valve 17 are positioned at distribution device 2, the cover body 18 of distribution device 2 are evenly equipped with aperture from inner outside diminishing air dispelling hole I 19, song Panel 20 is provided with aperture from the inner air dispelling hole II 21 being outwards gradually increased.Wherein, enlarging valve 17 is to exporting from air inlet pipe Gas once disperses, and beneficially gas is uniformly distributed in distribution device 2.The gas entering distribution device 2 can Being dispersed in further in distribution device 2 under the water conservancy diversion of the cover body 18 of curved slab 20 and hemisphere face shape, then gas is from cloth The air dispelling hole I 19 arranged on device of air 2 and air dispelling hole II 21 enter in cloth air chamber 4, so that gas is in uniformly dividing in cloth air chamber 4 Cloth, the most each heat exchanger tube 6 can uniform distribution gas.
In order to extend gas residence time in each heat exchanger tube, improve heat transfer effect, this utility model be embodied as Under: being provided above a flat board 14 at upper perforated plate in described cloth air chamber 4, position corresponding with each heat exchanger tube 6 on flat board 14 is all opened If a connection cloth air chamber 4 and the through hole 15 of corresponding heat exchanger tube 6, in each through hole 15, it is equipped with an eddy flow assembly 16, eddy flow assembly 16 are made up of central shaft and the fixing some helical blades on center shaft of the shape that is centrosymmetric.Spiral by eddy flow assembly 16 The guide functions of blade, makes the gas in cloth air chamber 4 enter each heat exchanger tube 6, thus gas after each through hole 15 in the shape of a spiral Body stroke in pipe is spiral yarn shaped, extends its time of staying in pipe.Additionally, due to the water conservancy diversion of helical blade is made With, gas mainly flows downward along tube wall when entering in pipe, and a small amount of gas passes through heat exchanger tube from tube hub, thus along tube wall Flowing gas with pipe outside cooling medium heat transfer effect more preferable.
