Description

Replaceable coiled electrolysis flue gas waste heat recovery heat-exchanger rig
technical field:
The utility model belongs to coloured high-temperature electrolysis flue gas heat recovery technical field, particularly one replaceable coiled electrolysis flue gas waste heat recovery heat-exchanger rig.
background technology:
In aluminum electrolysis industry, rectangle preheat exchanger is all employ in Ji Jia enterprise known at present, by the heat-exchange tube arranged side by side to the many groups of rectangle preheat exchanger welding, and on the outer surface of heat exchange tubulation, make multiple fin to increase the heat transfer area of heat-exchange tube, carry out heating cold water by high-temperature flue gas and carry out heat recovery.The drawback of this rectangle heat exchanger is: heat-exchange tube is fixed form with welding of rectangular vessel device, can only stop for a long time producing when changing heat-exchange tube so each, and one time replacement cost is comparatively large, can bring impact to production and cause damage simultaneously; If install by-pass flue additional can ensure normal production, but need the input cost that extra increase is larger; The complicate fabrication process of heat-exchange tube, and the special cost of material is higher, the heat transfer area of fin is also unsatisfactory, simultaneously current fin water tube stroke is shorter, heat transfer effect is poor, and fin also form larger resistance to flow of flue gas in flue gas heat exchange process, and dust, dust stratification are more, in addition the etch of high temperature corrosion flue gas and souring, also exacerbates the corrosion of finned heat-exchange tube and damaged etc. further.
summary of the invention:
The purpose of this utility model is for prior art above shortcomings, and to develop that a kind of structure is simple, operation is changed convenient, section emulates the advanced, economical and practical replaceable coiled electrolysis flue gas waste heat recovery heat-exchanger rig, this heat-exchanger rig can overcome the above-mentioned drawback that prior art is brought effectively, flue gas waste heat recovery effect is largely increased, its economic benefit and social benefit fairly obvious.
Technical scheme is: the feature of this replaceable coiled electrolysis flue gas waste heat recovery heat-exchanger rig is that it is by heat exchange shell, changeable type heat exchange coil, trustship support, horizontal water inflow pipeline, horizontal outlet conduit, water inlet manifold road, outfall sewer road, safety valve, movable top lid, flange components forms, the smooth outer surface of changeable type heat exchange coil is not provided with fin, changeable type heat exchange coil can be set to many groups, changeable type heat exchange coil is evenly distributed in heat exchange shell, trustship is propped up and is erected in heat exchange housing, changeable type heat exchange coil adopts parallel way to be packed on trustship support, the water inlet being packed in the changeable type heat exchange coil on trustship support is connected with horizontal water inflow pipeline by the mode of flange seal, the delivery port of changeable type heat exchange coil is connected with horizontal outlet conduit by the mode of flange seal, horizontal water inflow pipeline is connected with water inlet manifold road, horizontal outlet conduit is connected with outfall sewer road.In order to ensure the use safety of this device, can in water inlet manifold road, road is provided with safety valve with outfall sewer.Heat exchange shell is the main body of the utility model heat-exchanger rig, it installs the object being fixedly connected with all parts, heat exchange shell upper is provided with movable top lid, for preventing waste heat flue gas excessive, the necessary good seal of movable top lid, needing maintenance, when changing the changeable type heat exchange coil in heat exchange shell, movable top lid can be opened, as changed changeable type heat exchange coil, the flange being fixedly mounted with changeable type heat exchange coil is unloaded, by the boom hoisting on top, these changeable type heat exchange coils that need change are hung out, carry out again changing, so heat exchange shell is the permanent object used without the need to changing.And the heat exchange shell of the heat-exchanger rig of existing industry and heat exchange pipeline are one, therefore must change together, equipment replacement cost is higher.Changeable type heat exchange coil is the parts of heat transferring medium aquaporin, and its smooth outer surface is not provided with fin, makes simple, decreases washing away of gas-flow resistance simultaneously, therefore extend its service life.Changeable type heat exchange coil adopts parallel way to be packed on trustship support, the water inlet of changeable type heat exchange coil is connected with horizontal water inflow pipeline by the mode of flange seal, the delivery port of changeable type heat exchange coil is connected with horizontal outlet conduit by the mode of flange seal, because the delivery port of changeable type heat exchange coil, water inlet are all connected by the mode of flange seal, therefore can carry out as required dismantling, changing, the time of this dismounting and change is very of short duration, therefore minimum to Influence of production.Trustship support is the parts of fixing changeable type heat exchange coil.Horizontal water inflow pipeline is the connector of water inlet manifold road and changeable type heat exchange coil water inlet, and it is packed on heat exchange shell, and horizontal outlet conduit is the connector of outfall sewer road and changeable type heat exchange coil delivery port, and it is fixed on heat exchange shell.Water inlet manifold road is the total pipeline of cold water input.Outfall sewer road is the total pipeline that after heating, hot water exports.When replaceable coiled electrolysis flue gas waste heat recovery heat-exchanger rig uses, heat transferring medium water in changeable type heat exchange coil, the External electrolytic high-temperature residual heat flue gas of changeable type heat exchange coil, power and water solution high-temperature residual heat flue gas carries out exchange heat in flowing, reaches the object that waste heat is recycled.
The utility model replaceable coiled electrolysis flue gas waste heat recovery heat-exchanger rig is often organized heat exchanger tube and is adopted dish-type heat exchanger tube, head end is water inlet pipe, tail end is outlet pipe, increase water stroke in heat exchanger tube, the tube wall of heat exchange is simultaneously smooth stainless pipe, decrease electrolysis flue gas flow resistance and dust stratification situation, make simple, Inlet and outlet water head and the tail two ends are connected with heat exchanger shell by flange.Flange joint not only ensure that sealing, changes also simple simultaneously, changes one group for bad one group, economical and practical, greatly reduces replacement cost, and ensures normal production.By being welded on two groups of water inlet manifolds on heat exchange shell both sides and outfall sewer links together organizing changeable type heat exchange coil head and the tail more, a road is set to by often organizing changeable type heat exchange coil inlet channel, be connected with the water inlet manifold of heat exchange shell side, a road is set to by often organizing changeable type heat exchange coil outlet conduit, be connected with the outfall sewer of heat exchange shell opposite side, reach good heat transfer effect with this, meet the whole shower of company, heating and hot water demand.
The utility model has the advantages that: sufficient recycling has been carried out to the fume afterheat in Aluminum Electrolysis Production process, utilization through company in the middle of reality measures, according to combustion gas analysis of statistical data in early stage, year save natural gas expense and reach more than 184 ten thousand yuan, due to the use of this device, make my company eliminate two gas fired-boilers simultaneously, reduce the buying maintenance cost of equipment; Structure in addition due to this device is simple, makes, easy to use, cheap; Changeable type heat exchange coil is connected by flange, can carry out at any time as required dismantling, safeguard, overhaul, during replacing, heat exchange shell is without the need to changing, the changeable type heat exchange coil that need change directly is changed, and does not need the changeable type heat exchange coil changed also can retain, has saved equipment maintenance cost, and replacing construction shortens greatly, less to normal Influence of production.
