The utility model discloses overall structure reasonable in design carries out preliminary even material back, the effectual formation liquid film of rethread throttle pipe of dividing through the evenly distributed board to having improved heat exchange efficiency greatly, having increased effectual heat transfer area, the liquid circulation volume is low.
Description
Technical field
The utility model belongs to organophosphor chemical production equipment, is specifically related to a kind of downward film evaporator.
Background technology
The intermediate, additive, built agent etc. in the organic phosphorus compound field such as mainly use used as pesticides, chemical fertilizer, mineral floating, fire prevention antioxygen, plasticising toughness reinforcing, fire-retardant.Organic phosphorus compound almost penetrates into the every field of national economy.
Phosphorus atoms can with nonmetalloids all in the periodic table of elements and main group part metals element Cheng Jian with its distinctive bonding power, and this makes organic phosphorus compound huge number, and classification is various.Along with the develop rapidly of modern science and technology, to the detection of organic phosphorus compound and synthesizing mean constantly perfect, people carry out constantly improving for the production technology of organic phosphorus compound, thus improve the Energy Efficiency Ratio of each unit equipment in process of production.
For the production of organic phosphorus compound, owing to there is multiple heat sensitive material in organic phosphorus compound solution, boiling point is close, in order to evaporate single wherein one or more materials, heat exchange is carried out carrying out cannot adopting in heat transfer process the steam of higher temperature, therefore just need the temperature valued space reducing required steam, increase heat exchange efficiency.Film-formation result in the downward film evaporator of present stage in heat exchanger tube is poor, and rete is thicker and uneven, cannot complete abundant evaporation in limited stroke, causes solution enrichment low.
Summary of the invention
For above-mentioned Problems existing and deficiency, the utility model provides a kind of reasonable in design, and film-formation result is good, the downward film evaporator that heat exchanger effectiveness is high.
For solving the problem, the technical scheme taked is:
A kind of downward film evaporator, comprise cylindrical evaporation device cylindrical shell, described evaporator tube upper/lower terminal mates sealing respectively and is provided with upper perforated plate and lower perforated plate, between described upper perforated plate and lower perforated plate, axis is uniform is equipped with a series of heat exchanger tube, described evaporator tube sidewall top and the bottom are respectively arranged with steam air inlet and cooling water outlet, described upper perforated plate top coupling is sealedly connected with end socket, described end socket top is provided with feed pipe, is connected with and is uniformly distributed plate bottom described feed pipe.
Described being uniformly distributed between plate and described end socket is provided with suspension rod, and plate is corresponding with feed pipe goes out to be provided with solution tank in described being uniformly distributed, and described solution tank top is provided with seal cup.
Described heat exchanger tube top is inserted with throttle pipe, and described throttle pipe sidewall is fixed with the slotted-angle shelving set up at heat exchanger tube top, and bottom described throttle pipe, sidewall tilts to heat exchanger tube internal face, and matched in clearance between throttle pipe and heat exchanger tube.
Adopt technique scheme, acquired beneficial effect is:
The utility model overall construction design is reasonable, and after being uniformly distributed plate and carrying out preliminary uniform distributing, more effectively form liquid film by throttle pipe, thus substantially increase heat exchanger effectiveness, add effective heat exchange area, liquid circulation amount is low.Meanwhile, for the structural design of whole evaporimeter, eliminate traditional solution pressure impact, avoid the problem occurring pressure-drop in pipeline, impel the high energy efficiency ratio of whole evaporimeter, make the production technology of whole organic phosphorus compound be improved and improve.
