Abstract
The utility model relates to a single-sheet dismountable outflow free falling film plate type evaporator which belongs to evaporation and concentration equipment. The utility model adopts the way that each heating sheet is fixed by a fixing seat and is fixed in a casing by threaded bolts, and the heating sheets can be disassembled singly. In the heating sheets, heating is realized by steam. The outer surfaces of the heating sheets form a liquid film with even thickness for liquid which needs to be concentrated to freely fall via a distributor; the liquid film is heated to be evaporated to achieve the goal of evaporation. The utility model has the advantages that the heating sheets can be conveniently assembled and disassembled singly; the maintenance is convenient; the service life is prolonged.
Description
The utility model belongs to evaporation concentration equipment, relates to a kind of removable free outflow falling-film plate type evaporimeter.
At present, the evaporation concentration equipment of industries such as petrochemical industry, light industry, the recovery of papermaking alkali, food, medicine, environmental protection, metallurgy, desalinization adopts the evaporation efficiency height mostly, and is energy-conservation, less scaling, all welded type free outflow falling-film plate type evaporimeter of easy cleaning.This kind evaporimeter is because between the heating plates, and between heating plates and the housing, and internals etc. all adopts welding manner to be bound up, and becomes an indivisible integral device.Equipment is in operation if heating plates is impaired, can make that disengagement area reduces, efficient reduces.Chinese patent CN942092090 discloses a kind of dismountable plate type evaporimeter, can change heating plates, can change but three of heating plates are one group.That is to say that must all will change in the time of need changeing a slice, consumable material is still very big, and it is big to change difficulty to three one group.
The purpose of this utility model is exactly will overcome above-mentioned deficiency and the disconnectable free outflow falling-film plate type of a kind of heating plate monolithic evaporimeter that provides.
The solution that realizes the utility model purpose is by last shell (10), lower casing (2), steam manifold (16), thin liquid inlet pipe (9), indirect steam goes out pipe (6), heating steam inlet pipe (4), condensed water goes out pipe (18), concentrate goes out pipe (19), board-like heating plate (14) is formed, particularly on the well cabinet frame (22) in last shell (10) distributor (11) is installed, distributing pipe (25) on the distributor (11) is on " V " shape slit of per two board-like heating plates (14), adjust screw rod (24), distributing pipe (25) just moves up and down the gap of controlling between distributing pipe (25) and the board-like heating plate (14), also be provided with holder (13) on board-like heating plate (14), the well cabinet frame (20) in holder (13) and the lower casing (2) by Bolt Connection together.
The utility model has the advantages that easy accessibility, be convenient to maintenance, reduce material consumption, increase service life.
The utility model is described in further detail below in conjunction with accompanying drawing.

Lower casing (2) links by flange (5) and last shell (10), be connected with low head (1) under the lower casing (2), low head is associated with leg on (1), be fixedly connected with well cabinet frame (20) on the top of lower casing (2), holder (13) is installed on the board-like heating plate (14), and holder (13) links by bolt (21) and well cabinet frame (20).Well cabinet frame (20) plays the load-bearing effect to board-like heating plate (14).In last shell (10), have distributor (11) is installed on well cabinet frame (22) the well cabinet frame (22), distributor (11) is connected with thin liquid inlet pipe (9), the bottom of distributor (11) is provided with distributing pipe (25), distributing pipe (25) is to be on " V " shape slit of per two board-like heating plates (14), adjust the screw rod (24) on the distributor (11), distributor (11) is moved up and down, thereby driving distributing pipe (25) moves up and down, so just adjust the gap between distributing pipe (25) and the board-like heating plate (14), thereby also just adjusted sendout.The top of upper cover (7) has indirect steam to go out pipe (6), and indirect steam demister (8) is arranged below.The bottom of low head (1) has concentrate to go out pipe (19).Heating steam inlet pipe (4) links by flange (3) and heating steam arm (12), and heating steam arm (12) connects firmly on steam manifold (16), and steam manifold (16) is connected with the top of every board-like heating plate (14) respectively.Be provided with catch box (15) in the bottom of board-like heating plate (14), be connected with every board-like heating plate (14), be fixedly connected with condensed water arm (23) on the catch box (15), condensed water arm (23) goes out pipe (18) connection by flange (24) and condensed water and is communicated with, also be associated with fixed gas arm (17) on steam manifold (15), fixed gas pipe (17) goes out pipe (16) with condensing not and communicates.In lower casing (2), also be provided with several well cabinet frames and be used for supporting and stablize board-like heating plate (14).
During work, when heating steam is entered by heating steam inlet pipe (4), steam manifold (16) is all pressed the inner chamber of back mean allocation to every board-like heating plate (14), make board-like heating plate (14) keep certain evaporating temperature, condensed water goes out pipe (18) by the condensed water of bottom and flows out, and condensing does not flow out to go out pipe (16) by condensing not and discharge from the not condensing arm (17) of catch box (15) again.Need the liquid of evaporation and concentration to enter the outer surface that distributor (11) is evenly distributed to each board-like heating plate (14), form all thick liquid film, and freely descend along the outer surface of board-like heating plate (14) by thin liquid inlet pipe (9).The indirect steam that evaporates in the liquid film by evaporating between board-like heating plate (14), converges in the top of shell (10), through indirect steam demister (8), goes out pipe (6) by indirect steam and flows out, and the liquid after the evaporation and concentration goes out pipe (19) by concentrate and discharges.So just finished a concentration process of thin liquid, if need further to concentrate to connect one or some playscript with stage directions devices.
