Along with the fast development of China's industry, the demands of enterprise to oxygen argon nitrogen such as smelting iron and steel, petrochemical industry, Coal Chemical Industry, large chemical fertilizer sharply increase, thus drive rectifying column towards large-scale and super-hugeization development, and gas and liquid being uniformly distributed in tower is the subject matter that tower amplifies.Meanwhile, along with the continuous progress of packing technique, the exploitation of large porosity, low pressure drop new type high-efficient packing, all more and more higher to the requirement of gas initial distribution, the quality of distribution device in gas-fluid directly affects tower rectification efficiency and product quality.
At present, for even gas distribution in rectifying device mainly through perforate or the straight tube adding deflector, or the circulation pattern distribution device in gas-fluid adding deflector realizes, because above distributor cover plate or ring flat-plate, the existence of eddy current and recirculating zone can affect the uniformity of distribution of gas.Along with the large-scale of rectifying device and super-hugeization, the area that rectifying device air inlet pipe diameter and gas distributor occupy in tower also sharply increases, thus causes the area of eddy region above cover plate also sharply to become large, has a strong impact on the uniform effect of gas.Meanwhile, traditional gas distributor effectively can not utilize the kinetic energy of inlet gas, makes distributor have larger drag losses.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of distribution device in gas-fluid for rectifying device bidirectional guide is provided, this device is applicable to various forms of tower type container, successfully solve the problem that there is eddy current above distribution apparatus cover plate, realize the object that gas feed is evenly distributed in tower; Meanwhile, by utilizing the kinetic energy of a part of air inlet, reach the effect reducing distributor drag losses; In addition, this distribution apparatus can also make full use of the distance between inlet tube and liquid level, adds gas diffusion space, makes distribution of gas more even.
Technical solution of the present invention has been come by following technical solution, described a kind of distribution device in gas-fluid for rectifying device bidirectional guide, and it mainly comprises: connecting plate, side plate, baffle upper plate, chin spoiler; Described side plate has two pieces, left and right, and their one end is connected with described connecting plate, and is welded and fixed by the tower wall of this connecting plate and rectifying device, and the other end of described biside plate is fixedly connected with the supporting construction on tower wall by bolt; And the tower wall of described connecting plate, side plate and rectifying device surrounds nonocclusive gas passage; Be provided with polylith baffle upper plate and chin spoiler in described gas passage, and described baffle upper plate and chin spoiler are symmetrically arranged with tower central cross-section, form the two strands of air-flows upwards flowing and flow downward after making gas enter distributor, realize bidirectional guide.
Described baffle upper plate and chin spoiler two ends are fixedly connected by welding with left and right sides plate respectively, and be respectively arranged with at the place of being welded and fixed can ensure its rigidity and intensity upper reinforcing plate, gusset and lower reinforcing plate, gusset.
The distribution diametrically of described chin spoiler arranges by the mode of the tower section arc area equation surrounded between adjacent baffle, and described baffle upper plate arranges by equally spaced mode diametrically.
Described baffle upper plate and chin spoiler arrange by equally spaced mode in the axial direction.
Tool of the present invention has the following advantages:
1. in the present invention, the gas entering distributor is divided into two parts, a part moves downward after chin spoiler water conservancy diversion, encounter liquid level and kinetic energy is all consumed rear folding and upwards, another part spreads directly to tower body space above distributor after baffle upper plate water conservancy diversion, effectively utilize this portion gas kinetic energy, reduce the drag losses of distributor;
2. in the present invention, a part of gas entering distributor, by moving downward after the break-in of chin spoiler water conservancy diversion, is encountered liquid level folding and upwards, takes full advantage of the distance between inlet tube and liquid level, adding gas diffusion space, make distribution of gas more even;
3. in the present invention, several baffle upper plate is adopted to replace distributor top board, a part of gas is moved upward by baffle upper plate, the existence eliminated due to distributor top board makes gas from the large area eddy current produced above top board after distribution apparatus flows out and recirculating zone, makes distribution of gas more even;
4., in the present invention, by being provided with stiffener in the middle part of deflector, be provided with gusset to increase rigidity and the intensity of deflector with side plate junction, guarantee distributor in use deflector can not occur vibration and phenomenon of rupture.
The present invention not only can make distribution of gas more even, and can also reduce distributor resistance, has the advantages such as structure is simple, economical rationality, safety and stability, function admirable.
