Abstract
The utility model discloses a waste heat recycling device of an aluminum electrolysis smoke pipeline, which comprises heat exchange pipes, wherein one end of each heat exchange pipe is a media inlet, and the other end of each heat exchange pipe is a media outlet. The middle of each heat exchange pipe is a plurality of U-shaped structures bent continuously. The heat exchange pipes are located in the aluminum electrolysis smoke pipeline and fixedly connected with the pipe wall of the aluminum electrolysis smoke pipeline through bolts. Two ends of the heat exchange pipes penetrate through and extend out of the pipe wall of the aluminum electrolysis smoke pipeline. The number of the heat exchange pipes is more than one, and all the heat exchange pipes are connected in parallel or in series. The waste heat recycling device of the aluminum electrolysis smoke pipeline is reasonable in design and easy to process, and is arranged in the interior of the high-temperature smoke pipeline, thereby effectively using the partial heat energy in the smoke pipeline, lowering smoke temperature, reducing damage to follow-up recycled cloth bags, and being good in economic benefit after popularization.
Description
Technical field: the utility model relates to a kind of waste-heat recovery device, particularly relates to a kind of waste-heat recovery device of aluminium electrolytic flue pipeline.
Background technology: at present; People generally can collect post processing to the ducted high temperature harmful smoke of high-temperature flue gas; The high temperature harmful smoke is collected under the situation of negative pressure, enters into processor through pipeline then and carries out purified treatment, gathers dust like the entering bagroom etc.High-temperature flue gas carries out the nature cooling during through pipeline, has caused thermal waste.Simultaneously, because after high-temperature flue gas arrives bagroom, temperature is still than higher, also reaches more than 60 ℃ like the high-temperature flue gas of the aluminium cell temperature to the dust-precipitator place, and this cloth bag to dust-precipitator damages.
The content of utility model:
The utility model technical problem to be solved is: overcome the deficiency of prior art, provide a kind of simple in structure, cost is lower, the waste-heat recovery device of the aluminium electrolytic flue pipeline of easy dismounting and good effect of heat exchange.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of waste-heat recovery device of aluminium electrolytic flue pipeline; Contain heat-exchange tube, heat-exchange tube one end is the medium import, and the other end is a media outlet; Wherein, Heat-exchange tube is the U-shaped structural tube or the snakelike disk-like structure pipe of continuous bend, and the two ends of heat-exchange tube are run through the tube wall of aluminium electrolytic flue pipeline and gone out, and is fixedly connected with the tube wall of said aluminium electrolytic flue pipeline through bolt.
Said heat-exchange tube is more than one, and all heat-exchange tubes are parallel or tandem connects.
The beneficial effect of the utility model:
1, the utility model places the high-temperature flue gas pipe interior; Can do medium with gas or liquid in the heat-exchange tube, medium flows through in heat-exchange tube, in flue, carries out heat exchange; Deliver to available unit then; Effectively utilize this part heat energy in the flue, and reduced flue-gas temperature, reduce destruction the subsequent recovery cloth bag.
2, the utility model can wholely be changed through being bolted on the flue fast, handled easily, and do not influence continuous operation.
3, the utility model is reasonable in design, processing is simple, utilizes the molten steel pipe to do into a plurality of U fonts, is fixed on then on the plane, only leaves a delivery port on the plane and a water inlet gets final product.
4. the utility model heat-exchange tube adopts a plurality of U font structures, the medium long flow path, and heat exchange effect is good, and in addition, interchanger can adopt many rows to be provided with, and improves rate of heat exchange greatly.
5, the utility model medium only exists in the heat-exchange tube, do not contact with flue, thus can on flue, not form fouling, thus flue is not caused any destruction.
6, the utility model scope of application is wide, especially is used in the electrolytic cell gas cleaning pipeline of extensive electrolytic aluminium factory, and the heat energy of recovery can be done warming or bathing usefulness, and it is good to promote the back economic benefit.
Description of drawings:
Fig. 1 is the structural representation of the waste-heat recovery device of aluminium electrolytic flue pipeline.
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment the technical scheme of the utility model is done and to be further described.
Embodiment one: can be found out by Fig. 1; The waste-heat recovery device of aluminium electrolytic flue pipeline contains heat-exchange tube 2; Heat-exchange tube 2 one ends are medium import 1, and the other end is a media outlet 3, are a plurality of U-shaped structural tube of continuous bend in the middle of the heat-exchange tube 2; Heat-exchange tube 2 is positioned at aluminium electrolytic flue pipeline 4 and is fixedly connected with the tube wall of aluminium electrolytic flue pipeline through bolt, and the two ends of heat-exchange tube 2 are run through the tube wall of aluminium electrolytic flue pipeline 4 and gone out.
During use, medium import 1 is communicated with radiator respectively with media outlet 3, can realize warming.Perhaps, medium import 1 is connected with water inlet pipe, and media outlet 3 is communicated with shower head, does shower and uses.
Embodiment two: present embodiment and embodiment one are basic identical; Something in common does not repeat; Difference is: heat-exchange tube is more than two, the parallel connection of all heat-exchange tubes, and itself and connector can be in the aluminium electrolytic flue pipelines; Also can outside the aluminium electrolytic flue pipeline, confirm as required.
Embodiment three: present embodiment and embodiment one are basic identical; Difference is: heat-exchange tube is more than two, and all heat-exchange tube tandems connect, and its polyphone joint can be in the aluminium electrolytic flue pipeline; Also can outside the aluminium electrolytic flue pipeline, confirm as required.
The connected mode that changes the concrete shape of heat-exchange tube, the quantity that changes heat-exchange tube and connected mode and change heat-exchange tube and aluminium electrolytic flue pipeline can be formed a plurality of embodiment, is the common variation of the utility model, does not detail one by one at this.
