Abstract
The invention discloses a three-grade-film-falling distribution heater. The three-grade-film-falling distribution heater comprises a heater cylinder (21), heating tubes (22) and a tube plate (23). A first-grade distribution spraying head (27) is installed in the top of the heater cylinder (21). A second-grade distribution disc (26) is installed at the portion, in the heater cylinder (21), between the first-grade distribution spraying head (27) and the tube plate (23). Tube openings of the heating tubes (22) extend to the portion above the tube plate (23) and are provided with sawtooth-shaped overflowing openings (29). According to the three-grade-film-falling distribution heater, due to a three-grade-film-falling distribution mode, material film-type distributing is even, film-type flowing evaporation of materials is formed in the heating tubes, the aim that coking and walling drying of the heating tubes are avoided is achieved, and the effect of improving the heating efficiency of the heater is achieved.
Description
Technical field
The present invention relates to mechanized equipment field, specifically relate to a kind of heater being applied to the evaporimeter of the conglomeraties such as pharmacy, food, chemical industry, environmental protection.
Background technology
At present, mechanical steam recompression (being called for short MVR) evaporimeter is that recycling Secondary-steam heating principle makes the feed liquid in evaporator system maintain fluidized state, improve the concentration of feed liquid to reach technical requirement, it comprises feed pump, condensate pump, discharging pump, vavuum pump, heater, separator, compressor.Heater (falling film type) exists that cloth film is uneven, the problem of the dry wall of the easy coking of feed liquid, and the import of its heating tube (i.e. the charging mouth of pipe) maintains an equal level mutually with tube sheet, what it had weld seam and crator between the two is uneven that to make feed liquid be distributed in heating tube inwall uneven.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and the three grades of falling liquid film distributing heaters a kind of multi-stage falling-film being provided, being evenly distributed.
Objects of the present invention are achieved through the following technical solutions: three grades of falling liquid film distributing heaters, comprise heater cylindrical shell, heating tube, tube sheet, at the top of described heater cylindrical shell built with one-level distribution showerhead, in described heater cylindrical shell and between this one-level distribution showerhead and tube sheet, secondary distributing disc is equipped with at place, and the import of described heating tube extend out to the top of tube sheet and has zigzag overfall.
Adopt after the present invention, these three grades of falling liquid film distribution modes, achieve material cloth film even, make material in heating tube, form membranaceous flow evaporation, reaching heating tube can not the object of the dry wall of coking, reaches the effect improving the heater efficiency of heating surface.Widely, the heater quality of falling liquid film distribution also directly affects a whole set of evaporator device to its range of application, improves the effect of heater, that is to say the evaporation efficiency that improve a whole set of evaporator device.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail.
Fig. 1 is the mounting structure schematic diagram of the present invention's three grades of falling liquid film distributing heaters.
Fig. 2 is the structural representation of the zigzag overfall of heating tube in Fig. 1.
Detailed description of the invention
Known with reference to Fig. 1, Fig. 2, the present invention's three grades of falling liquid film distributing heaters, comprise heater cylindrical shell 21, heating tube 22, tube sheet 23, at the top of described heater cylindrical shell 21 built with one-level distribution showerhead 27, in described heater cylindrical shell 21 and between this one-level distribution showerhead 27 and tube sheet 23, secondary distributing disc 26 is equipped with at place, the import of described heating tube 22 extend out to the top of tube sheet 23 and has zigzag overfall 29 (being three grades of distribution modes), thus is formed as three grades of distributed architectures.Described secondary distributing disc 26 has several distribution holes 28, between described secondary distributing disc 26 and tube sheet 23, support bar 24 is housed.
In three grades of falling liquid film distributing heaters, first order distribution mode is (seedpod of the lotus shape) one-level distribution showerhead, and the material entering heater is that fountain falls, and can not cause very flood column impact.Second level distribution mode is secondary distributing disc, has a lot of distribution holes above it, and around heating tube below every six distribution hole correspondences, the feed liquid of landing is uniformly distributed.Third level distribution mode is the import of heating tube is zigzag overfall, the certain distance of tube sheet is stretched out in the import of this heating tube, and this heating tube import of stretching out is made into zigzag and makes its inner tubal wall groove be chamfering 45 degree, the feed liquid flowed down from the distribution hole of secondary distributing disc is upwards assembled on tube sheet again, and dirty along inner slope wall along the zigzag overfall (breach) of heating tube import, the crator of former heating tube hydroforming can be avoided and affect the cloth film of feed liquid in heating tube inside.The heater quality of falling liquid film distribution also directly has influence on evaporimeter complete equipment, improves the evaporation effect of heater, that is to say the evaporation efficiency that improve a whole set of evaporator device, make product more have competitive advantage.The falling film type MVR evaporator device energy consumption that the present invention applies is low, operate steadily, security performance is high, and it is widely used in multiple industries such as pharmacy, food, chemical industry, environmental protection, alcoholic, milk processed, beverage, sugaring.
Claims (2)
