The utility model has the advantages of smart conception, simple structure and compact layout; in addition, the space occupation is reduced, the diameter of the equipment is greatly reduced, the manufacturing cost is lowered, and the transportation is convenient.
Description
Technical field
The utility model relates to a kind of double-deck condenser/evaporator, and the double-deck condenser/evaporator of liquid falls in particularly a kind of arc gas that rises.
Background technology
Air separation plant is made up of main unit such as air cleaner, air compressor, purifier, fractionating column, decompressor.Compositions such as main heat exchanger, Shang Ta, Xia Ta, condenser/evaporator, liquid air liquid nitrogen subcooler, argon column part are housed in the fractionating column ice chest.The main condenser evaporimeter is the tie of getting in touch with tower and following tower, and it is used for reflux heat exchange between the gas nitrogen of the liquid oxygen that gets off and the rising of following top of tower of tower bottom, makes vaporization of liquid oxygen become gas oxygen, and gas nitrogen is condensed into liquid nitrogen.The main condenser evaporimeter is a requisite important heat transmission equipment in the distillation system, and the quality of its work is related to the power consumption and the ordinary production of whole air separation unit.
Along with developing rapidly of heavy constructions such as metallurgy, petrochemical industry, Coal Chemical Industry, the supporting with it air separation plant of corresponding requirement also tends to maximize.At present, in large and medium-sized empty sub-item, what generally use is horizontal condenser/evaporator and present double-deck condenser/evaporator.Because horizontal condenser/evaporator separates with king-tower, it is big that ice chest becomes, and increases its floor space and manufacturing cost, and make overall PIPING DESIGN become very complicated, and pipeline density is big, and the site operation difficulty is big.Be connected with downspout, riser between double-deck condenser/evaporator lower floor and the upper strata, following tower nitrogen enters each plate type heat exchanger by central tube, and liquid nitrogen goes out from the central tube interlayer to draw.Ascending, descending pipe and central tube take up space greatly, and board-like unit is arranged compact inadequately, cause the space waste bigger, and device diameters is increased, and in large-scale empty sub-item, are subjected to the restriction of means of transportation such as railway, highway, can't transport.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of arc gas that rises to fall the double-deck condenser/evaporator of liquid.This bilayer condenser/evaporator is skillfully constructed, simple in structure, compact in design has reduced taking the space; Device diameters reduces greatly, has reduced manufacturing cost and has been convenient to transportation.
For achieving the above object, the utility model solves the technical scheme that its technical problem adopts and is:
The double-deck condenser/evaporator of liquid falls in a kind of arc gas that rises, comprise hollow housing and the dividing plate that is arranged on the housing middle part, described dividing plate is divided into housing two-layer up and down, be provided with the upper strata condenser/evaporator in the housing of upper strata, be provided with lower floor's condenser/evaporator in lower floor's housing, described dividing plate is provided with two arcuate indentation and is fixedly connected with two first risers, is fixedly connected with two second risers between every first riser and the housing.
As optimal way, the both sides of described first riser are provided with U type breach.
As optimal way, described first riser is to be welded on the dividing plate.
As optimal way, described second riser is to be welded on first riser.
As optimal way, described upper strata condenser/evaporator and lower floor's condenser/evaporator are plate-fin heat exchanger.
As optimal way, described upper strata condenser/evaporator and lower floor condenser/evaporator are close to mutually and gather layout.
Adopt said structure, key is:
1, the arcuate indentation on housing, the dividing plate and first riser are formed arcuate channel, and two groups of arcuate channels now are set, and are connected two second risers between first riser and housing, and passage is divided into three parts again.Utilize the mid portion of arcuate channel, make lower floor's oxygen enter the upper strata; Utilize the both sides part of arcuate channel, make the upper strata liquid oxygen enter lower floor.
2, cancelled the traditional star-like distribution in board-like unit and by the central tube ways of connecting, adopted plate-fin heat exchanger to be close to mutually to gather structure, the circulation of gas, liquid is finished by arcuate channel.
3, the both sides of first riser are provided with U type breach, and the liquid that is beneficial to the upper strata flows into lower floor thus.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:
1, adopt plate-fin heat exchanger to be close to mutually to gather arrangement, do not use central tube, device structure is compact to design, effectively utilizes the space;
2, device diameters reduces greatly, has reduced manufacturing cost and has been convenient to transportation, helps device and maximizes.
