The specific embodiment
In the description hereinafter, provided a large amount of concrete details and the utility model has been understood more completely so that provide.Yet, it will be apparent to one skilled in the art that the utility model can need not one or more these details and be able to enforcement.In other example,, describe for technical characterictics more well known in the art for fear of obscuring with the utility model.
In order thoroughly to understand the utility model, detailed structure will be proposed in following description.Obviously, the execution of the utility model is not limited to the specific details that those skilled in the art has the knack of.The preferred embodiment of the utility model is described in detail as follows, yet except these were described in detail, the utility model can also have other embodiments.
Below with reference to accompanying drawing the embodiment of the utility model is made detailed description.
With reference to figure 1, be sketch map according to the afterheat recovery type lampblack purifying system 100 of an embodiment of the utility model.This system 100 comprises fume pipeline 10 and heat-exchanger rig 20, and this heat-exchanger rig 20 is arranged in the fume pipeline 10, in heat-exchanger rig 20, is provided with heat-absorbing medium.This heat-absorbing medium can be water or other analogs.In the present embodiment, with water be example.On the surface of heat-exchanger rig 20, also be provided with the oleophobic layer.Also be provided with container to hold the oil droplet that tumbles from the oleophobic layer in the lower end of heat-exchanger rig 20.
In use, flue gas produces after extracted to flue by air exhauster, and flue gas can heat water wherein during through heat-exchanger rig, when promoting water temperature, has reduced the cigarette temperature.Reduction along with the cigarette temperature; Oiliness particulate matter in the oil smoke can stick on the surface of heat-exchanger rig; Through being arranged on this lip-deep oleophobic layer, making the oiliness particulate matter that adheres to tumble to the container of end along the surface of heat-exchanger rig, thereby realize the purpose of clean oil smoke.Meanwhile, the oil smoke temperature reduces, and no longer has energy dissipation and thermal pollution problem during discharge, and the water in the heat-exchanger rig can continue to use after being heated, and has also reached purpose of energy saving from another angle.
Preferably, also be provided with active carbon layer 30 at the end of fume pipeline 10, adsorbable uncooled small size particle and eliminate peculiar smell just can obtain clean oil smoke thus.Active carbon can be changed once by every three months.
In addition, though be laid with one deck oleophobic layer, can not prevent fully that the oiliness particulate matter from adhering on the outer tube wall on the surface of heat-exchanger rig; Therefore; Said system 100 also is provided with self-stripping unit 50 and regularly cleans, and to keep the cleaning of heat-exchanger rig copper pipe tube wall, guarantees the heat exchange effect.This self-stripping unit 50 is connected with heat-exchanger rig 20, utilizes the hot water of heat-exchanger rig outlet to wash away to obtain high-temperature steam heat exchanging device.Can carry out a self-cleaning every month.
For reaching better heat exchange effect, can suitably increase the heat transfer temperature difference in the heat-exchanger rig, therefore can before heat-exchanger rig 20, increase a refrigerating plant 40, promptly this refrigerating plant 40 is arranged on the upstream side of heat-exchanger rig 20.Water passes through refrigerating plant earlier to reduce water temperature before the entering heat-exchanger rig is participated in heat exchange, with the bigger heat transfer temperature difference of acquisition, thereby reach enhanced heat exchange, further reduces the purpose of cigarette temperature.This refrigerating plant both can be the compression mechanism device for cooling, also can be semiconductor cooling device.But, can select in the time of can guaranteeing the heat exchange effect, so refrigerating plant selectivity use as the case may be without refrigerating plant processings of lowering the temperature when inlet water temperature is lower.
Through after the whole system, the oil smoke temperature reduces and does not contain polluter, no longer has energy dissipation and thermal pollution problem during discharge, has realized the purpose of environmental protection; Simultaneously, the feedwater in the heat-exchanger rig is heated, and can obtain a certain amount of hot water, has utilized fume afterheat, has reached purpose of energy saving from another angle.
For the not enough abundant area of water resource, water circulation system 60 can be set, this water circulation system 60 is connected with heat-exchanger rig with refrigerating plant.Each hot water that obtains through supercooling (can cool off naturally also can through the refrigerating plant cooling) but after repetitive cycling use.
Adopt copper pipe 21 to carry out heat exchange in the above-mentioned heat-exchanger rig 20, the copper pipe bundle takes in-line arrangement to arrange, and singlely is arranged as snakelikely, and water can therefrom flow through, referring to figs. 2 and 3.
