Description
Technical field
The utility model relates to a kind of heat exchanger, relates in particular to a kind of cyclonic separation heat exchanger.
Background technology
Existing heat exchanger is common shell-and-tube or plate type heat exchanger mostly, this heat exchanger is not too suitable for the fume afterheat that those contain the big metallurgical industry furnace of fume amount, because contain a large amount of dusts in this flue gas, the heat exchanger surface dust stratification can reduce operational effect; Reduce heat transfer efficiency; Also can cause wearing and tearing by the heat exchanging device; Reduce the service life of heat exchanger, also will often keep in repair and clean; Can increase operation and maintenance cost.
The utility model content
The utility model purpose is to provide a kind of cyclonic separation heat exchanger, to realize thoroughly solving heat-transfer surface dust stratification and the wear problem in the metallurgical industry furnace ash-laden gas heat recovery process, and reduce operation and maintenance cost, prolong the service life of heat exchanger, improve heat transfer efficiency.
The purpose of this utility model is achieved through the following technical solutions: flue cyclonic separation heat exchanger has the Whirlwind barrel of leading scroll and the whirlwind cone of bottom and the vertical tube of bottom by top and constitutes, be provided with inlet flue duct on Whirlwind barrel top, at Whirlwind barrel and whirlwind cone inwall water cooling tube is arranged circumferentially, the bottom of described water cooling tube with advance cold water pipe and be communicated with, its top is communicated with the hot-water outlet pipe.
Described inlet flue duct tangentially is the inclination angle of downward 10-12 degree along Whirlwind barrel, when guaranteeing that the dust constaining air-flow tangentially enters Whirlwind barrel, a downward velocity component is arranged, and quickens the sedimentation of dust, improves the flue dust separative efficiency; Its height value of described inlet flue duct is got about 0.65-0.75 times of Whirlwind barrel internal diameter, and its inlet-duct area determines for 14-18m/s that by import cigarette speed it is definite that its discharge area is pressed cigarette speed 22-28m/s.
The cone angle of described whirlwind cone is the 30-36 degree.
The internal diameter of described Whirlwind barrel is pressed the interior flue gas flow rate 5-6m/s of cylindrical shell and is determined.
Described aditus laryngis internal diameter of leading scroll is the 35-42m/s value by cigarette speed, the outlet internal diameter of leading scroll is the 28-32/s value by cigarette speed, lead the degree of depth that scroll inserts Whirlwind barrel get inlet flue duct inlet bottom to the 0.45-0.55 of cylindrical shell inner top height doubly, the 0.06-0.07 that the distance that the center line of leading scroll departs from the center line of Whirlwind barrel is got the Whirlwind barrel internal diameter is doubly.
The height of Whirlwind barrel is definite at 1.1-1.5 by its ratio with the internal diameter of cylindrical shell.
The inwall of described Whirlwind barrel and cone forms with the abrasionproof castable refractory is integrated poured, and its outer wall forms with insulated pouring material cast, is provided with metal casing at the outermost layer of Whirlwind barrel and cone.
Described material of leading scroll adopts the anti-wear-resisting alloy steel of heatproof, and outer wall applies the insulated pouring material.
Advantage of the present utility model: the ash-laden gas that industrial furnace is discharged enters the cylindrical shell of cyclonic separation heat exchanger along the cylindrical shell tangential direction through the inlet flue duct of cyclonic separation heat exchanger, under action of centrifugal force, dust more than 99% separates with flue gas, and the vertical tube that falls into the cyclonic separation heat exchanger is regularly discharged through lock gas unloading valve, simultaneously flue gas is passed to the sub-fraction heat in the water in the water cooling tube of cyclonic separation heat exchanger, ash-laden gas flows out by leading scroll hardly, thereby thoroughly solve heat-transfer surface dust stratification and wear problem in the metallurgical industry furnace ash-laden gas heat recovery process, and reduce operation and maintenance cost, prolong the service life of heat exchanger, improve heat transfer efficiency.
