A PLATE EVAPORATOR OF THE FALLING FILM TYPE AND A PLATE EVAPORATOR APPARATUS HAVING SUCH A PLATE EVAPORATOR ARRANGED IN A HOUSING

摘要

the plate-shaped evaporator according to the present invention falling film type in accordance with the device, has an inlet 11 for liquid to be evaporated substantially vertically arranged heat transfer in the state with the plate the spaces between plates (4 ) packages a housing attached to the inside of - a plate interspace for each two form the evaporation space (28) for at least partial evaporation of the liquid and, between the other plate space of at least a portion of the heat emitting vapor condensation the first sealing portion (13, 14) to form a distribution chamber 27 at the upper portion of the space between the plates forming the, evaporation space (28) a-condensation space to form a 30 for dispensing chamber 27 of each of the passage to be spaced apart along the width of the package (17, 18) at least one evaporation space (28) and the liquid being in flow communication by a heat transfer plate (4) is plate package in the upper part has a through opening 16 that is aligned to form a passage extending through a-a further includes. Is connected to the inlet is a long pipe (11), extending along its length within the passageway, the pipe is a hole having a circumferential wall distributed along the length of the pipe, to be evaporated in the distribution chamber from the inlet 11 through the hole to supply a liquid distribution chamber 27 and are in flow communication. ;
