Abstract

The invention discloses a flue afterheat recovery device, comprising flue casing, water inlet pipe, water distributor, water tank, heat exchanger, and central column, where the water inlet pipe is connected with the water distributor, the water distributor is equipped at the upper end of the flue, the central column is embedded in the middle of the flue, and a spiral flue plate is arranged in the flue casing and coiled round the central column and made with many small through holes. The spiral flue plate makes the fume spirally move up and the cooled water flow out from the small through holes, and water beads quickly move up in the direction of the resultant force generated by gravity and driving force of spiral upward movement of the fume and then mix with the up-moving fume and are heated, and then flow out through the small through holes of the next stage flue plate and are heated by the fume, and so from the top down, the contact area of the water beads and the fume is large and the moving distance is long, thus prolonging the heat exchange time of water beads and fume, and raising heat exchange efficiency. And it is vertically equipped, occupying less area and only needing a water pump, consuming less quantity of electricity.

Description

A kind of device for recovering residual heat of flue
Technical field:
The present invention relates to a kind of device for recovering residual heat of flue.
Technical background:
Take away the heat of 10-20% at the high-temperature flue gas of the flue of boiler and lithium bromide central air-conditioning and kiln, wasted the energy, polluted environment.The patent No. is: a kind of flue gas multi-stage waste heat recovery device of 03248678.2, can reclaim flue gas residual heat preferably, its shortcoming is: 1, absorbed heat during the flue gas horizontal motion, the contact area of the globule and flue gas is little, and heat exchange efficiency is desirable not enough, and 2, device lateral installs, be applicable to that horizontal direction has the waste heat recovery than the large space flue, occupation area of equipment is big, and 3, need many water pumps, the electricity consumption of equipment amount is big.
Summary of the invention:
The object of the present invention is to provide a kind of heat exchange efficiency height, occupation area of equipment is little, power consumption is few device for recovering residual heat of flue.
The object of the present invention is achieved like this, this device for recovering residual heat of flue comprises flue shell, water inlet pipe, water knockout drum, water tank, heat exchanger, centered cylinder, and water inlet pipe connects heat exchanger, water segregator capable is in the flue upper end, in the middle of centered cylinder is located in the flue.The spiral flue sheet is set in the flue shell, and the spiral flue sheet twines centered cylinder, executes having many small through hole on the flue sheet at spiral shell.
Because the setting of spiral flue sheet, make flue gas in the shape of a spiral form move upward.The flue gas direction is opposite with the flow direction of water, cooling water flows out from the small through hole of spiral flue sheet and meets the spiral flue gas that moves upward, the resultant direction that the smoke power that the globule moves upward along gravity and spiral rapidly produces is moved, thereby can not form water curtain, can not produce resistance to flue gas, and mix with flue gas, and be heated, the small through hole by next stage spiral flue sheet flows out again, heated by flue gas again, so from top to bottom, the contact area of the globule and flue gas is big, and move distance is long, thereby prolonged the heat-exchange time of the globule and flue gas, improved heat exchange efficiency, constantly heated from low temperature to high temperature, can be heated to 80-90 ℃ high-temperature-hot-water at last: this device is vertical installation, floor space is little, and, only needing the separate unit water pump, power consumption is few.
Down for the utility model is described in further detail in conjunction with the accompanying drawings:
Description of drawings:
Accompanying drawing 1: spiral flue sheet waste-heat recovery device structural representation;
Accompanying drawing 2: be Fig. 1 C-C sectional structure chart;
Accompanying drawing 3: be Fig. 2 B-B sectional structure schematic diagram;
Accompanying drawing 4: the spiral flue sheet has the mansion TV structure schematic diagram of little tank;
Accompanying drawing 5: be Fig. 4 D-D sectional structure schematic diagram;
The specific embodiment:
The 1-accompanying drawing 5 with reference to the accompanying drawings;
This smoke canal flue gas waste heat recovery device is by Pyatyi: water knockout drum 1, vertical gas pass 2, spiral flue sheet 3, water fender 4 (or little tank 15), centered cylinder 5, horizontal flue 6, coolant outlet 7, cyclic water tank 8, water pump 9, plate type heat exchanger 11, circulating water pipe 13 and water inlet pipe 10, outlet pipe 12 and the small through hole 14 etc. that need add hot water are formed.
Water knockout drum 1 is contained in the top of vertical gas pass 2, is to be made by hollow metal tube, and this figure is a cross, on many small through hole are arranged.It is corresponding with water fender 4 quantity of spiral flue sheet 3.Spiral flue sheet 3 outsides and vertical gas pass 2 welding; 3 inboard and centered cylinder 5 welding of spiral flue sheet, centered cylinder 5 can be hollow, also can be solid.Spiral flue sheet 3 has many small through hole 14.The through hole of every grade of (promptly 360 ℃) spiral flue sheet 3 below welding water fender 4 (perhaps, offering the little tank 15 of several equal portions, the many small through hole 14 of brill in the little tank) at spiral flue sheet 3 equal equal portions.According to the requirement of exhanst gas outlet temperature and cooling water outlet temperature, multiple coil flue sheet 3 is set.Horizontal flue 6 is connected with vertical gas pass 2.The lower end of vertical gas pass 2 is provided with a coolant outlet 7.Coolant outlet 7 connects a cyclic water tank 8.Cyclic water tank 8 connects water pump 9 and plate type heat exchanger 11 and centered cylinder 5 successively by circulating water pipe 13, if (, centered cylinder 5 is solid, and circulating water pipe 13 connects water knockout drums 1) plate type heat exchanger 10 connects the water inlet pipe 10 of the water that needs heating and outlet pipe 12 etc. again respectively.
The process that contains the high hot water acquisition of hot quality is: the cooling water after 11 exchanges of plate type heat exchanger flows out from water knockout drum 1, drop on equably on the first order spiral flue sheet 3, be divided into four parts by water fender 4-, water is blocked by water fender 4, flow out from the small through hole 14 of spiral flue sheet 3, the resultant direction that the smoke power that the globule moves upward along gravity and spiral rapidly produces is moved, mix with flue gas carry out heat exchange after, fall on the second level spiral flue sheet 3, gather the water fender upper end, flow out from the small through hole 14 of spiral flue sheet 3, mix with flue gas and to carry out heat exchange, repeat said process, cooling water by repeatedly with the flue gas Hybrid Heating, becoming high-temperature-hot-water flows in the cyclic water tank 8 from exporting 7, by circulating water pipe 13, pump into plate type heat exchanger 11 with water pump 9, the water that heat is required heating is taken away and is cooled, enter hollow cylinder 5 again, constitute a closed circulation.Cold water flows out from outlet pipe 12 after injecting 11 heating of plate type heat exchanger from water inlet pipe 10.
