Description
Technical field
The utility model is related to a kind of coil pipes, more particularly, to a kind of industrial coal powder boiler of organic heat carrier lower disc
Pipe.
Background technology
Currently, the burner hearth for the square plate form of tubes that industrial coal powder boiler of organic heat carrier mostly uses greatly, no matter its combustion system
Using the arrangement that liquidates, preposition, bottom is set or overhead, and lower furnace portion ash port is to be in large-area open, therefore very much
Boiler factory largely uses heat-insulating material using bottom, arranges more slag dropping tubes；Or it is received using in rectangular coil pipe lower interface
Contraction makes a prodigious heat insulation-type slag-removing hopper, is used as slag；The disadvantage is that the heat-insulating material usage amount at scene is very big, work
Journey amount is also larger, and during use, and it is very big to shrink manufacture one using a large amount of heat-insulating materials in bottom and coil pipe lower interface
Heat insulation-type slag-removing hopper, since in boiler operatiopn, intraductal working medium temperature is higher, negative pressure air distribution etc. cause flame control it is improper, make
It is excessively high at temperature of lower, coking is generated, or even large area refractory material is caused to fall off, causes outer side seal plate all to be damaged, make
It is unable to operate normally at boiler.
Chinese patent CN104791748A discloses double once-through cycle fluid bed injection boilers with pipe laying and evaporation coil,
Belong to uphole steam generator technical field.For the uphole steam generator that solves existing Natural Circulation, there are water screen tube inner walls easily to tie
Salt crust, heat transfer deterioration can be led to and booster problem for a long time by going down.Pipe laying is arranged in low speed bed in furnace body, and evaporation coil is surround
The inner circumferential side wall winding of furnace body constitutes furnace wall cooling, and evaporation coil is connected to upper header, in upper header and drum
Steam-water separator connection；Into the steam water interface in drum through steam-water separator carry out steam-water separation, the water isolated into
The hydrospace for entering drum, the steam isolated enter the air space of drum, and the hydrospace of drum is connected to evaporator, and evaporator is logical
It crosses connecting tube four to be connected to external whizzer, external whizzer is connected to by connecting tube seven with mixer, mistake
The superheated steam outlet of hot device is connected to mixer；The air space of drum is connected to the air inlet of superheater.This patent is for height
The lower furnace space of coal dust organic heat carrier furnace, the organic heat carrier walked in boiler tube are imitated, the flow velocity of control 3.0m/s or so has
Effect prevents organic heat carrier from can go bad；Rational medium flow resistance is controlled, the power consumption of system will not be increased；It also can be effective
Reinforce heat transfer；Lower part coil pipe cooperation top burner flame makes rational trapezoidal shape (ensureing that flame will not be adherent), and lower part connects
Burner hearth slag mouth is connect, burner hearth slag mouth size is greatly reduced, adiabatic area is allowed to and reduces, greatly prolong slag mouth uses the longevity
Life；After the coil pipe oil inlet of lower part, top is fuel-displaced with the effective transition of upper boiler coil pipe and to be connect, and ensures the flowing of boiler whole system
It is smooth.
Utility model content
The purpose of this utility model is exactly to provide a kind of service life to overcome the problems of the above-mentioned prior art
Industrial coal powder boiler of organic heat carrier lower part coil pipe long, safe and reliable, use scope is wide, boiler performance is good, easy to maintenance.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of industrial coal powder boiler of organic heat carrier lower part coil pipe, to process the helical coil to be formed by continuous bend
Road combines, and often encloses between the tube wall of pipeline and keeps gap, and the entrance of pipeline connects oil inlet header, outlet by fairlead draw with
Remaining heating surface connects, and oil inlet header is mostly to use process starting point, effectively reduces lower part coil temperature, and be allowed to coking can
Energy property is greatly reduced；Outlet is drawn using several coil pipes, and convenient to the diversity offer of structure arrangement.
Preferably, the gap between tube wall is 8-10mm.
Preferably, the gap between tube wall carries out complete penetraction and fusion in welding sealing by round steel or band steel, is welded using with steel pipe
The mode of sealing both increases heat transfer area, also ensures coil pipe globality.
Preferably, which is in isosceles trapezoid in longitudinal cross sectional shape, and lower part coil pipe is made trapezoidal shape, lower part
Burner hearth slag mouth is connected, burner hearth slag mouth size is greatly reduced, adiabatic area is allowed to and reduces, greatly prolong slag mouth uses the longevity
Life, keeps the stability of boiler.
Preferably, the angle of the two sides of isosceles trapezoid and horizontal direction is more than 55 °.
It is further preferred that the two sides of isosceles trapezoid and the angle of horizontal direction are 56-65 °.
Most preferably, the two sides of isosceles trapezoid and the angle of horizontal direction are 60 °, and guarantee is here formed as good slag
Angle, convenient for slagging tap.
Preferably, which is fixed on the steelframe of boiler bottom, and lower part is also connected with burner hearth slag mouth.
Compared with prior art, the utility model has the following advantages：
One, service life is long：Due to trapezoidal shape lower part coil pipe, reduces the adiabatic area of slag mouth, improve slag mouth
Service life.
Two, safe and reliable：Since the lower part coil pipe globality is fine, oil inlet section coil pipe is mostly used, is effectively reduced
Lower part coil temperature, the possibility for being allowed to coking are greatly reduced.
Three, use scope is wide：Since such boiler quantity that puts into operation now is increasing always, and go out as module
Factory, event easy for installation can promote use.
Four, boiler performance is good：Because the lower part coil pipe does not influence entire conduction oil flow and heating surface arrangement, simultaneously
The peculiar shape of lower part coil pipe reduces the size of slag mouth and adiabatic area, reduces input, with docking for slag remover
It is more convenient, also increase the service life of the slag notch..
Five, easy to maintenance：The feature for not increasing maintenance difficulty, therefore keeping the maintenance of miniature boiler convenient.
