The utility model content
The technical problems to be solved in the utility model provides the film-distributing device of the good vertical tube falling-film absorber of a kind of feed liquid distribution consistency degree.
For solving the problems of the technologies described above, the utility model is to have air inlet on housing top, and the side is provided with inlet; Bottom at the housing inner chamber is provided with tube sheet, is fixed with heat exchanger tube on the tube sheet, and the upper end of heat exchanger tube is communicated with filming device; Enclose in the side of housing and to be covered with a circle and to be subjected to liquid bath, inlet is communicated with being subjected to liquid bath; Circumferentially be distributed with one group of spout hole that connects housing on housing, the spout hole that passed through by liquid bath is communicated with the housing inner chamber; Be provided with distributing disc in the housing inner chamber between spout hole and tube sheet, filming device is fixed on the middle part of distributing disc, has liquid distributing hole on distributing disc; Filming device has tangential cloth fenestra between distributing disc and heat exchanger tube.
The utility model in use, 1, liquid is entered by inlet and is subjected to liquid bath, arrive the spout hole that circumferentially distributes from the cylindrical shell upper edge after certain liquid level and overflow to liquid-distributing disk, liquid flows on the tube sheet from the liquid distributing hole on the distributing disc, liquid rotates into the heat exchanger tube inwall by the tangential opening of filming device, forms liquid film.2, gas phase enters distributing disc upper periphery space by air inlet, and gas phase can be assigned in the every heat exchanger tube by filming device equably like this, realizes gas-liquid distribution mutually noninterfere.
The utility model can be provided with baffle plate over against the air inlet place in housing.Like this, gas phase is eliminated the initial kinetic energy and the flow perturbation of air-flow by baffle plate by air inlet, make air-flow evenly enter distributing disc upper periphery space from circumference, and gradually to center flow, it is evenly distributed on whole cross section, and gas phase can be assigned in the every heat exchanger tube by filming device equably like this.
Adopt the beneficial effect that technique scheme produced to be: the utility model has the different liquid distributing hole in aperture in the distributing disc radial direction, and liquid is carried out quadratic distribution, guarantees that liquid level is identical on the tube sheet; Gas phase evenly enters the distributing disc upper space by baffle plate from circumference, air-flow is evenly distributed on whole cross section, gas phase can be assigned in the every heat exchanger tube by filming device equably like this, and gas phase during from circumferential central distribution to liquid even distribution also played certain facilitation; Realized gas-liquid distribution mutually noninterfere.The utility model is simple in structure, easy to process, production efficiency is high, use after, the feed liquid film forming evenly, owing to circumferentially do not seal, elasticity is fine, be convenient to install.Be applicable in the large-scale vertical tube falling-film absorber of industries such as chemical industry, light industry, metallurgy, food.
