Abstract

The utility model discloses a device arranged with a multi-stage waste-heat recovering device in a horizontal flue, or arranged with a stage-I waste-heat recovering device in a vertical flue and stage-I or above waste-heat recovering device in a horizontal flue, and consists of a waste-heat recovering device and a heat exchanger. The waste-heat recovering device is composed of an atomizer, a water tank, a water pump and a flue, etc.. The atomizer is arranged on the top side of the flue. The water tank is equipped underside the flue. A water-isolating plate is equipped at the conjunction portion between two adjacent flues. The water tank of the stage-I waste-heat recovering device is connected with the atomizer of the stage-II waste-heat recovering device. A water outlet pipe of the final-stage water tank is connected with a water inlet pipe of the heat exchanger, thus obtaining the hot water of high temperature of 90 degrees Celsius. The utility model increases the heat efficiency of the heat supply equipment, saves the energy, reduces the waste gas discharge, protects the environment, lowers the recovering cost and increases the service life of the equipment.

Description

A kind of flue gas multi-stage waste heat recovery device
Technical field:
The utility model relates to a kind of flue gas condensed water latent heat and sensible heat waste-heat recovery device.
Technical background:
Take away the heat of about 15-25% at the high-temperature flue gas of the flue of boiler and bromination reason central air-conditioning and kiln, wasted the energy, polluted air.The patent No. is the sensible heat that 02223946.4 device for recovering residual heat of flue mainly reclaims flue gas, and as reclaiming latent heat, investment is big, and it is big to capture the space.In Europe, a kind of waste-heat recoverer is arranged, be a sprayer to be housed on vertical chimney top.The sprayer lower end is provided with several water fenders that stagger each other, forms water curtain on the water fender mouth, exists following shortcoming: the one, and water can not multistagely heat, mostly about 50 ℃; The 2nd, produce flue gas resistance, and need to increase air-introduced machine.
Summary of the invention: a kind of device that multistage waste-heat recoverer is set in horizontal flue is provided, or the device that one-level and the waste-heat recoverer more than the one-level are set in one-level and the horizontal flue is set in vertical gas pass, comprise waste-heat recoverer, heat exchanger, heat exchanger is outside flue, and waste-heat recoverer is made up of sprayer, water tank, water pump and flue etc.Sprayer is contained in the upper end of flue, water tank is contained in the lower end of flue, flue is provided with water-stop sheet in the junction surface, the radiator drain of first order waste-heat recoverer connects the sprayer of second level waste-heat recoverer through water pump, connections successively at different levels, the outlet pipe of afterbody water tank is connected with the heat exchanger water inlet pipe.
Because, in horizontal flue, adopted above-mentioned multistage waste-heat recoverer, or in vertical gas pass, be provided with one-level and the waste-heat recoverer more than the one-level are set in one-level and the horizontal flue, the water at low temperature that makes first order recovery, through the second level, the waste-heat recoverer of the third level etc. continues heating, can be heated to 90 ℃ high-temperature-hot-water at last.The water fender that do not stagger can not produce resistance to flue gas.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1: in horizontal flue, having adopted the device schematic diagram of level Four waste-heat recoverer.
Accompanying drawing 2: for the device schematic diagram of the waste-heat recoverer that is provided with three grades in one-level and the horizontal flue is set in vertical gas pass.
The specific embodiment:
Reference diagram, this smoke canal flue gas waste heat recovery device are four and add heat exchanger 7, heat exchanger water inlet pipe and water outlet pipe 8,9, flue 10 and water-stop sheet 11 etc. by waste-heat recoverers such as sprayer 1, water inlet pipe 2, outlet pipe 3, water tank 4, water pump 5, overflow pipes 6 and form.
Sprayer 1 is to be made by metal tube, on many aperture sprayer units are arranged, be installed in horizontal flue 10 upper ends.In the flue junction surface of adjacent waste-heat recoverer water-stop sheet 11 is set, prevents that the interior water of flue of adjacent waste-heat recoverer from flowing mutually.The sprayer 1 of first order waste-heat recoverer links to each other with water inlet pipe 2, and water inlet pipe 2 links to each other with water pump 5, and water pump 5 links to each other with water tank 4, and water tank 4 is equipped with overflow pipe 6 and links to each other with flue outlet pipe 3.Water pump 5 one ends link to each other with water tank 4, and the other end links to each other with the water inlet pipe 2 of the sprayer of second level waste-heat recoverer.After said structure repeated four times, near the entrance point of flue, water pump 5 linked to each other with heat exchanger 7, the port of export of heat exchanger 7 and flue, and promptly the water inlet pipe 2 of the sprayer 1 of first order waste-heat recoverer links to each other.Heat exchanger water inlet pipe and water outlet pipe 8,9 connects the water inlet pipe and water outlet pipe of the water that needs heating respectively.
The process that contains the high hot water acquisition of hot quality is: at flue 10 ports of export, after water is cooled off by heat exchanger 7, water inlet pipe 2 by first order waste-heat recoverer (N1), pump into flue 10 from sprayer 1 ejection atomizing, about 80 ℃ water vapour flue gas that is cooled to of discharging with second level waste-heat recoverer (N2) mixes, water flows out from outlet pipe 3 after absorbing heat, enter water tank 4, pump into second level waste-heat recoverer (N2) by water pump 5 again and carry out the heat temperature raising second time, enter third level waste-heat recoverer (N3) again and carry out heat temperature raising for the third time, arrive end, i.e. the fourth stage waste-heat recoverer (N4) of close flue 10 import departments.At this moment, higher from the water temperature that outlet pipe 3 flows out, about 90 ℃, pump into heat exchanger 7 by water pipe 5 again and enter heat exchange, water at low temperature turns back to first order waste-heat recoverer (N1).Like this, can obtain to contain higher, the about 90 ℃ hot water of hot quality.From back three grades of waste-heat recoverers (N2) (N3) the main effect of (N4) be that hot water with first order waste-heat recoverer (N1) continues heat temperature raising.
