Description
Technical field
The present invention relates to a kind of oil burning boiler, refers specifically to the anti-laying dust oil burning boiler of tail heat reclamation type.
Background technology
Boiler is to use very universal thermodynamic apparatus, oil burning boiler due to complete, the no flue dust of burning, automatically control
System perfecting, emission can reach the environmental requirement of residential block exhaust emissions, thus be very environmentally friendly boilers, extensively should
The occasion higher for environmental requirement.
Combustor and boiler body be the core component and capital equipment of oil burning boiler, the wherein primary structure of combustor again
That centrifugal blower collectively constitutes with remaining auxiliary equipment, combustor and centrifugal blower it is continuous, stably, reliably working extremely closes
Key, because the occasion that oil burning boiler uses all contains certain dust mostly, when combustor and centrifugal blower work, air-flow passes through
At a high speed because centrifugation, dust granule can depart from air-flow phase and deposit and be attached to draught fan impeller during the draught fan impeller of rotation
On.
Because the centrifugal blower fan blade wheel rotating speed of combustor is general all higher, as long as with the presence of micro dust in air-flow, when long
Between work after can all accumulate more dust, so as to change draught fan impeller rotation balance, if draught fan impeller to dust without from
Net effect is not also cleared up in time, will static state cumulative and that draught fan impeller is altered in steps and dynamic equilibrium, so as to produce
Vibration.Come off once the dust that running into has part hardened is vibrated, the dynamic rotary away from blower fan will balance, then produce immediately
Raw judder, this may trigger serious personnel and equipment safety accident.
Therefore, if a kind of draught fan impeller of combustor can be designed, automatic cleaning can be carried out and just caused without worry
Dust accumulates, and all has especially important meaning for keeping the reliable and stable work of combustor and preventing security incident.
On the other hand, substantial amounts of heat energy is often contained in the tail gas of oil burning boiler discharge, if can effectively reclaim, for carrying
The efficiency of high boiler, and realize that energy-saving and emission-reduction are all significant.
The content of the invention
The technical problem to be solved in the present invention is exactly overcome the deficiencies in the prior art, there is provided a kind of simple and practical, energy
The anti-laying dust oil burning boiler of tail heat reclamation type of automatic cleaning dust.
For overcome the deficiencies in the prior art, the present invention takes following technical scheme：
A kind of anti-laying dust oil burning boiler of tail heat reclamation type, including combustor and boiler body, it is characterised in that：Boiler body
Offgas duct successively connection water preheater, air preheater tube side after empty；The water inlet pipe connection of water preheater shell side is high-order
Pond, outlet pipe connect boiler feed water interface, the air inlet pipe connection air of air preheater shell side, escape pipe through water pump, valve
Connect combustor；The combustor centrifugal blower fan blade wheel includes impeller backboard, impeller panel and blade, and blade arrangement is into impeller axle
Radially, centrosymmetric hollow anti-water-drop-shaped；Hollow anti-water-drop-shaped blade connection impeller panel is simultaneously welded to form with impeller backboard
Impeller bodies；Impeller panel is provided with air inlet, impeller backboard is fixed by rivet and connection shaft seat, axle bed pass through axis hole and blower fan
Axle is connected.
Chimney is provided with the offgas duct emptying.
The hollow anti-water-drop-shaped blade is combined into by the welding of two panels Curved surface metal, and has symmetrical streamline profile.
When oil burning boiler works, the flame combustion gas of combustor injection exchanges heat in boiler body with water, generates certain pressure
Saturated vapor carry out heat supply.Boiler exhaust gas connects water preheater tube side by pipeline, enters bottom from top and goes out, and from a high position
The water in pond carries out shell and tube countercurrent flow, and the water after heat exchange is conveyed after water pump pressurizes, connect through Valve controlling by boiler feed water
Mouth enters boiler internal, realizes first order tail recuperation of heat.
Water preheater bottom tube side discharge tail gas, imports air preheater bottom tube side by pipeline, heats air inlet
Emptied after the air of preheater by chimney.Air inlet lines are arranged at air preheater shell side top, and shell side bottom is connected by pipeline fires
Burning machine air entry, newly enter air and countercurrent flow once again is carried out in air preheater with tail gas, realize second level tail recuperation of heat, give
Combustor provides preheated fresh air, promotes burning.
The draught fan impeller of the present invention is in use, because blade design is into hollow anti-water-drop-shaped, and sharf radial center pair
When claiming, thus rotating at a high speed, blade surface has centrifugation self purification under the action of the centrifugal force, makes dust by centrifugal action
And can not adhere to, dynamic, the static balancing of impeller are not interfered with thus, will not more accumulate dust；The skill of this blade construction
Art scheme, it is particularly suitable for the big wide impeller combustor of delivery air amount and uses.
Compared with prior art, beneficial effects of the present invention also reside in：
Boiler exhaust gas realizes tail recuperation of heat and energy-saving and emission-reduction by two-stage countercurrent heat exchange, can effectively reduce combustor
Diesel fuel consumes, although the longer recuperation of heat in exhaust emissions path is thorough, realizes that tail gas conveys by heat energy expanding gas, thus
Power consumption is relatively low, can produce more significant economize on electricity, energy-conservation, emission reduction effect, it may have preferable economic benefit.
Blade design is into hollow anti-water-drop-shaped, and sharf radial center is symmetrical, makes its blower fan backboard connected and face
The anti-relative torsion of plate, extruding rigidity are extremely strong, the fracture of fan blade connection backboard root caused by can preventing long-time use.
Blade design is into hollow anti-water-drop-shaped, and sharf radial center is symmetrical, even with relatively thin board making wind
Machine impeller can also obtain higher intensity, ensure stable, reliable use, can save material, be easy to make, be also beneficial to equipment
Light and handyization.
Hollow anti-water-drop-shaped blade has streamline profile, and steadily skimming over property is fabulous for blade air, so fan operation noise
It is especially small, improve working environment.
By blade ingehious design into hollow anti-water-drop-shaped, and the symmetrical shape of sharf radial center realizes the present invention
The real-time cleaning of dust, extend the service life of equipment and can effectively prevent the security incident that dust accumulation triggers, before
Scape is wide.
