Abstract
The utility model provides a holding furnace smoke and dust and smoke and dust waste heat recovery device, including gas collecting channel, flue, outer exhaust fan, circulating pipe way, the gas collecting channel sets up in the holding furnace top, is equipped with the entry of being convenient for to feed in raw material in gas collecting channel and holding furnace junction, the access door is installed to entry one side, the gas collecting channel is connected to flue one end, the outer exhaust fan of other end connection, the flue comprises inlayer pipeline and outer layer pipeline, forms the intermediate layer between the two -layer pipeline, the circulating pipe way is arranged in the intermediate layer of flue, the air outlet of outer exhaust fan passes through the flue and connects in the holding furnace. The the device design and installation is simple, convenient, preparation low cost, and purifying effect is good, has installed the circulating pipe way of retrieving the smoke and dust waste heat simultaneously, can be with the water of heating for workman's daily life perhaps need use hydrothermal part in the production, and practice thrift the energy, has reduceed the cost simultaneously.
Description
Technical field
The utility model relates to technical field of electrolytic aluminum production, is specifically related to a kind of holding furnace flue dust and flue dust waste-heat recovery device.
Background technology
In Aluminum Electrolysis Production, after the aluminium liquid transported back from potroom is transported to job shop, first aluminium liquid to be poured in holding furnace and carry out removing the gred, stir, leave standstill, just can enter down one procedure.In the process that aluminium liquid removes the gred in holding furnace, stir, leave standstill, certain dust and flue dust can be produced, certain harm is caused to production environment and employee.
In addition, the temperatures as high of holding furnace flue dust 200 degrees Celsius, usually rational utilization ways is not had, cause heat to be lost in vain, cause the waste of the energy, for this reason, we need to install one can deal carefully with holding furnace flue dust, and the retracting device of flue dust waste heat can be utilized, dust and flue dust are dropped to minimum to the harm that production environment and employee cause, and the efficiency utilization of the energy can be ensured.
Utility model content
For overcoming the above problems, the utility model provides a kind of holding furnace flue dust and flue dust waste-heat recovery device, comprise gas skirt, flue, exhaust fan, circulating water pipeline, described gas skirt is arranged at holding furnace top, the entrance being convenient to feed in raw material is provided with at gas skirt and holding furnace junction, described inlet side is provided with entrance door, described flue one end connects gas skirt, the other end connects exhaust fan, described flue is made up of inner layer pipe and outer layer pipe, interlayer is formed between two-layer pipeline, described circulating water pipeline is arranged in the interlayer of flue, the air outlet of described exhaust fan is connected in holding furnace by flue.
Further, described inner layer pipe adopts the good aluminum pipe of heat conductivility to be made, and scribbles insulation material layer inside described outer layer pipe.
Further, described circulating water pipeline adopts thread-shaped to be wound on the inner layer pipe of flue.
The beneficial effects of the utility model: 1, the utility model adopts the mode that is circularly set of flue, can solve the raising of the cost that fume recovery brings, eliminate the harm of flue dust to environment and staff's health simultaneously.2, the installation of this apparatus design is simple, convenient, cost of manufacture is cheap, clean-up effect is good, the circulating water pipeline reclaiming flue dust waste heat has been installed simultaneously, by the water of heating, for the daily life of workman, or the part using hot water can be needed in producing, and saved the energy, reduce cost simultaneously.
