Description
Technical field
The utility model relates to a kind of flue gas waste heat recovery apparatus.
Background technology
Country more and more payes attention to energy-saving and emission-reduction, and boiler (kiln) flue gas waste heat recovery is obtaining widely promotion and application.Nucleus equipment in the flue gas waste heat recovery engineering is heat-exchanger rig, and the core component of heat-exchanger rig is heat pipe.What generally use at present is the finned tube that the direct water flowing of gravity-type heat pipe and the inside of heat transfer medium is housed in the vacuum tube, and the material of heat pipe has carbon steel, stainless steel, aluminium alloy, copper pipe etc., and the shape overwhelming majority of heat pipe is circular, and small part is ellipse or rhombus.One end of circular heat pipe puts a-circle-by-a-circle thin type fin, and the other end is smooth, is placed in the smoke box of retracting device with an end of fin, and a smooth end is placed in the water tank of retracting device.All resistances certain to the mobile formation of flue gas of circle or ellipse or rhombus heat pipe, and when having flue gas by heat pipe heat pipe the front and the back side is heated inhomogeneous and the problem such as the positive easily dust stratification of heat pipe, this has greatly affected the heat-transfer effect of heat pipe, and its heat-transfer effect is sharply descended.
Summary of the invention
The purpose of this utility model is, the technical deficiency for existing heat pipe exists provides a kind of flue gas waste heat recovery apparatus made from the flat-shaped aerofoil profile heat pipe of porous, with improve heat exchange efficiency high with reduce production costs.
The technical solution of the utility model is, a kind of flue gas waste heat recovery apparatus, comprise the heat pipe that heat transfer medium is housed in framework and the framework, be provided with dividing plate and this dividing plate in the described framework framework is divided into the water tank of upside and smoke box two parts of downside, described heat pipe vertically passes dividing plate; An end face upside of described water tank is provided with water inlet, and the downside of another end face of water tank is provided with delivery port; Place the smoke box end face of delivery port downside to be provided with into mouth, and another end face of smoke box is provided with outlet flue.
The heat pipe wall of described heat pipe is the flat-shaped aerofoil profile of porous.By with disposable extrusion modling behind magnesium (aluminium) the alloy bar material process hot mastication, can be cut into arbitrary length according to the retracting device size, the width of the wall thickness of heat pipe, hole count, fin also is to determine according to the application needs of retracting device.Heat transfer medium in closed porous heat pipe compared with can absorb heat the quickly evaporation and meet cold solidifying of the pipe in existing single aperture.Fin and flat tube are integrated, conduct heat more direct, and thermal resistance is minimum, and effect is better, also can be at flue gas contact jaw welding transverse fin to increase heat exchange area.Flue gas in retracting device radially parallel when the heat pipe drag minimization, heating surface area is large and evenly, without file blocking surface, can dust stratification.The proportion of magnesium is about 1.9, the proportion of aluminium is about 2.8, carbon steel and stainless proportion are about 7.8, the advantage such as can find out thus that magnesium alloy has compared with aluminium alloy and stainless steel (carbon steel) that the cost of material is low and installation weight is light, simultaneously, the heat transfer coefficient of magnesium (aluminium) alloy ratio stainless steel and carbon steel is large, is more suitable for doing heat pipe.
Place the heat pipe wall outside in the smoke box to be provided with transverse fin.
Described tank top is provided with leakage port.
Described smoke box bottom is provided with the condensed water sewage draining exit.
A side of described smoke box is provided with the smoke box access door.
A side of described water tank is provided with the water tank sewage draining exit.
The outer wall of described water tank is provided with heat-insulation layer.
Be provided with temperature sensor in the described water tank, described water inlet and delivery port are equipped with magnetic valve.
Boiler (kiln) high temperature (more than 160 ℃) flue gas enters in the retracting device smoke box from advancing mouth, radially pass through heat pipe, heat transfer medium is subjected to thermal evaporation in the heat pipe, when being moved upwards up to retracting device water tank end, steam meets the cold solidifying liquid that becomes, and emit heat, water temperature raise after this part heat was absorbed by water.Heat transfer medium liquid flows downward along heat pipe hole inwall by own wt, is subjected to again thermal evaporation when flowing to the smoke box end.So move in circles, the heat of high-temperature flue gas is constantly absorbed by water by adopting heat pipes for heat transfer, and final flue-gas temperature is just discharged from exhaust opening from being reduced to more than 160 ℃ below 60 ℃, and running water is warmed up to more than 60 ℃ from normal temperature and flows out from delivery port.Retracting device divides upper and lower two-layer, the upper strata is water tank, and lower floor is smoke box, and the centre separates with dividing plate, integral body is welded with metal framework, add the heat-insulation layer insulation, waterbox design has sewage draining exit and leakage port, and smoke box is designed with condensed water sewage draining exit and access door, solenoid control is passed through in running water water inlet and water outlet, leaving water temperature is sent to by temperature sensor that switch board is set by switch board and the control leaving water temperature, in case reach setting value, automatic opening/closing magnetic valve then.
Flue gas waste heat recovery apparatus described in the utility model can be widely used in the flue gas waste heat recovery of Industrial Boiler (kiln) and civil boiler, realizes the energy-saving and emission-reduction purpose; And heat exchange efficiency is high, and production cost is low.
