Abstract
The invention relates to a lower tower for an air separation device. The lower tower comprises liquid receiving tanks connected with a tower plate and a liquid receiving dish connected with a bearing body. The liquid receiving tanks are arranged in the liquid receiving dish at intervals. A plurality of pipelines are further arranged at the bottom of the liquid receiving dish. According to the lower tower, a layer of original liquid receiving tanks are divided into two layers of liquid receiving tanks, so the down flow speed of liquid can be decreased, liquid eddies at the bottom of the lower tower can be slowed down, the lower tower is more stable in operation, and the safety of the device is improved.
Description
Technical field
The present invention relates to air separation field, refer in particular to the lower tower of a kind of air separation equipment.
Background technology
Cryogenic air separation flow process contains following components: air compression system, the purification system removing moisture in air and impurity etc., the heat-exchange system of cooling liquid air and the rectifying tower system of seperating air by rectification, main separation process carries out in rectifying column, and rectifying tower is made up of upper tower, condenser/evaporator, lower tower, in lower tower, raw air is cooled to or close to saturation state, following tower operating pressure enters Xia Ta, air participates in rectifying through each block column plate from bottom to top, high pure nitrogen is obtained at lower top of tower, nitrogen is all condensed in condenser/evaporator, a part is as the phegma of lower tower, dirty along column plate from top to bottom, caloic exchange is carried out with gas, finally can obtain oxygen-enriched liquid air at tower bottom and flow at the bottom of tower by connecing liquid bath, but easily form fluid vortex in bottom, cause and rock, thus reduce the stationarity of lower tower, for this reason, we have developed the lower tower of a kind of air separation equipment, original one deck is connect liquid bath is two-layer respectively connects liquid bath, what can reduce liquid flows down speed, slow down the fluid vortex of lower tower bottom, thus it is more steady when lower tower is run, improve the security performance of equipment.
Summary of the invention
The present invention seeks to provide a kind of air separation equipment lower tower to overcome the deficiencies in the prior art, original one deck is connect liquid bath is two-layer respectively connects liquid bath, what can reduce liquid flows down speed, slow down the fluid vortex of lower tower bottom, thus more steady when lower tower is run, improve the security performance of equipment.
For achieving the above object, the technical solution used in the present invention is: the lower tower of a kind of air separation equipment, comprises the liquid dish connecing liquid bath and be connected with supporting mass be connected with column plate; The described liquid bath that connects is disposed in liquid dish; The bottom of described liquid dish is also provided with many pipelines.
Preferably, the inwall interval 1-2mm of the end and liquid dish that connect liquid bath described in is arranged.
Preferably, described supporting mass and liquid dish are fixedly connected by welding.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Original one deck to be connect with lower tower that liquid bath is two-layer respectively connects liquid bath by air separation equipment of the present invention, and what can reduce liquid flows down speed, slows down the fluid vortex of lower tower bottom, thus more steady when lower tower is run, and improves the security performance of equipment.

Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the sectional view of air separation equipment of the present invention with lower tower;
Accompanying drawing 2 is the amplification right view of the lower tower of air separation equipment of the present invention;
Accompanying drawing 3 is A place partial enlarged drawing in Fig. 1;
Wherein: 1, column plate; 2, supporting mass; 3, liquid bath is connect; 4, liquid dish; 5, pipeline.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1-3 is the lower tower of air separation equipment of the present invention, comprises and column plate 1 connecing liquid bath 3 and by welding the liquid dish 4 be connected with supporting mass 2, increasing bonding strength, thus improve security performance by rivet interlacement; The described liquid bath 3 that connects is arranged in liquid dish 4, and the inwall interval 1mm of the end and liquid dish that connect liquid bath is arranged; The bottom of described liquid dish 4 is also provided with many pipelines 5; During work, liquid flows into from column plate 1 and connects in liquid bath 3, and overflowed in inflow liquid dish 4 by two ends when connecing after liquid bath 3 is filled, what can reduce liquid flows down speed, slows down the fluid vortex of lower tower bottom, is finally flowed out by many pipelines 5.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Original one deck to be connect with lower tower that liquid bath is two-layer respectively connects liquid bath by air separation equipment of the present invention, and what can reduce liquid flows down speed, slows down the fluid vortex of lower tower bottom, thus more steady when lower tower is run, and improves the security performance of equipment.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
