Abstract
The utility model discloses a novel highly-efficient heat-exchange cyclone dust extractor with the functions of waste heat recovery and dust removal for environmental protection. The structure thereof is characterized in that the dust extractor comprises three sections, i.e. an upper section, a middle section and a lower section. The upper section is arranged for the heat exchange between a heat pipe and the air, wherein air enters an air heat-exchange chamber from an air inlet to exchange heat with the heat pipe, and is discharged from an air outlet afterwards. In the middle section, fume enters a fume distributing chamber from a fume inlet for distribution and exchanges heat with the heat pipe. In the lower section, the distributed fume enters a cyclone for dust removal and heat exchange, after which the purified fume is collected by a fume collecting chamber and is discharged from a fume outlet, and the separated fume dust drops into an ash hopper through an ash discharge port.
Description
Technical field
The utility model relates to a kind of new and effective heat exchange type cyclone dust collectors, and in particular, it relates to a kind of function of recovering waste heat that both had, the exchange type dust arrester that has the dedusting environment friendly function again.
Background technology
The exhaust gas temperature of the present overwhelming majority's hot equipment such as flame furnace is all more than 750 ℃, and dust content is very high, has both needed to carry out waste heat recovery to going out kiln gas, needs again it is carried out dust removal process.But, if separately flue gas is carried out waste heat recovery, then carrying out dust removal process, flue dust will block the passage of heat exchanger.Simultaneously, stick to the flue dust on the heat-transfer surface, can increase the thermal resistance of heat-transfer surface, reduce heat exchanger effectiveness, unfavorable to waste heat recovery.In addition, stick to flue dust on the heat exchanger heat-transfer surface to the inner surface of heat exchanger corrosiveness again.On the contrary,, then carry out waste heat recovery, in cleaner, will reduce the temperature of flue gas so, cause the fume afterheat loss if separately flue gas is carried out dust removal process.
Summary of the invention
At the problem of prior art situation and existence, the purpose of this utility model provides a kind of high efficient heat exchanging formula cyclone dust collector.It had both had function of recovering waste heat, had the dedusting environment friendly function again.And easy to operate, compact conformation, little, the reliable safety of equipment investment and, very easily promote practical and existing apparatus transformed.
The technical solution of the utility model realizes as follows:
This equipment is made up of smoke inlet, smoke distributing chamber, whirlwind, casing, casing upper perforated plate, middle tube sheet, lower perforated plate, ash bucket, fume centralized chamber, air ports, fin heat pipe, exhanst gas outlet.High efficient heat exchanging formula deduster design feature is: equipment is divided into three parts, and top is the heat exchange of heat pipe and air, and air enters the air Heat Room by air intake, carries out heat exchange with heat pipe, and the air after the heat exchange is discharged through air outlet slit; At device middle part, flue gas is entered by smoke inlet that smoke distributing chamber distributes and carry out heat exchange with heat pipe; In the device bottom, the flue gas after distributing enters whirlwind and carries out dedusting and heat exchange, and flue gas after being purified is discharged by exhanst gas outlet after concentrate the fume centralized chamber, and the flue dust of separation falls into ash bucket by ash discharging hole..
The utility model compared with prior art the utlity model has following advantage and good effect:
(1) selects heat pipe conduct heat transfer element efficiently for use, the heat transfer efficiency height, compact conformation, heat exchange area is big, and is safe and reliable, can avoid cold fluid and hot fluid to mix, the hot-fluid conversion of heat pipe and boast that grey characteristic can prevent that industrial heat transmission equipment dew point corrosion and dust from stopping up, layout and flexible for installation, fault is few, is convenient to repair.And can utilize the design feature of heat pipe, as the sub-inner core of whirlwind, with the supporting use of whirlwind.
(2) key problem in technology of the present utility model is to adopt axial admission, the structural design and the manufacturing of whirlwind of following exhaust.It has exchange capability of heat again when having sufficiently high efficiency of dust collection.Ash-laden gas is by after axially entering cyclone separator, and under the effect of spiral stream guidance blade, flue dust is downward twist in cylindrical shell, flows towards cone, forms outer rotational gas flow.Dusty gas produces centrifugal force in rotary course, the grit of severe greater than gas got rid of to wall, grit with lose inertia force after wall contacts, fall along wall by the momentum of entrance velocity and downward gravity, enter ash releasing tube.When air-flow arrives a certain position, cone lower end, promptly with same direction of rotation from the cyclone separator middle part, by counter-rotating down and on, continue to do helical flow, rotational gas flow in forming.The interior rotational gas flow that rises enters blast pipe and is discharged by the cyclone body bottom.
(3) the utility model is easy to operate, cost is low, reliable safe, very easily promote the use of and existing apparatus transformed.
Description of drawings
Accompanying drawing 1 is the structure principle chart of the utility model device.
Among the figure: the 1-air outlet slit; The 2-smoke inlet; Tube sheet in the 3-casing; 4-whirlwind; 5-purifies the fume centralized chamber; 6-casing lower perforated plate; The 7-flue-dust retainer; 8-purifies exhanst gas outlet; The 9-casing; 10-inlet flue gas distributor chamber; 11-air Heat Room; 12-casing upper perforated plate; The 13-heat pipe.
The specific embodiment
Referring to accompanying drawing 1, the utility model device comprises by smoke inlet 2, inlet flue gas distributor chamber 10, whirlwind 4, heat pipe 13, flue-dust retainer 7, purify fume centralized chamber 5, air Heat Room 11, purify exhanst gas outlet 8, it is characterized in that, described ash-laden gas enters smoke distributing chamber 10, after the distribution of smoke distributing chamber 10, enter whirlwind 4, ash-laden gas under the effect of whirlwind 4 guide vanes on one side to the ash discharging hole moving linearly, make high speed rotary motion around its central axis on one side, under action of centrifugal force, isolate the flue dust in the ash-laden gas, flue dust falls into flue-dust retainer 7 by ash discharging hole again under the effect of gravity, finish separating of flue dust and flue gas.Purification flue gas in whirlwind 4 then enters purification fume centralized chamber 5 through exhaust core pipe under it and concentrates, and discharges by air-introduced machine.
In dedusting, flue gas in inlet flue gas distributor chamber 10 be arranged in 13 heat exchange of indoor fin heat pipe, and flue gas in entering whirlwind 4 with whirlwind 4 in helical fin heat pipe 13 carry out heat exchange, flue gas is passed to heat pipe with heat, in air side, by the heat exchange of heat pipe, heat is passed to the air that needs heating, thereby cold air is preheating to a certain temperature.
