Description
Technical field
The utility model relates to residual heat from boiler fume and reclaims field.Relate more specifically to a kind of biomass boiler energy-saving appliance.
Background technology
Energy-saving appliance arranges on boiler exhaust gas passage usually, and it utilizes boiler tail flue gas waste heat to carry out heating boiler feed water, and boiler feedwater, after energy-saving appliance heating, improves boiler feed temperature, effectively can reduce exhaust gas temperature, improves boiler thermal output, saves fuel.In running, the fault major embodiment of energy-saving appliance is dust stratification, wearing and tearing, corrosion etc.
Be that the steam generator system of fuel still adopts traditional structure energy-saving appliance in the market with living beings, as shown in Figure 1, energy-saving appliance 1 is arranged on boiler exhaust gas passage, its top is provided with air inlet Connectivity Section 2, bottom is provided with communicating exhaust gas section 4, communicating exhaust gas section 4 is directly placed on cement pedestal usually, the double supporting member making energy-saving appliance 1, the sidewall 3 of energy-saving appliance 1 is provided with some ribs 8, in order to the maintenance of energy-saving appliance, its access hole 5 is arranged on the sidewall of air inlet Connectivity Section 2 or communicating exhaust gas section 4.But this structure is suitable for coal burning boiler system, its dust stratification is few, and the time between overhauls(TBO) is long.For biomass fuel boiler; the ash content particle diameter produced after biomass fuel combustion is little, and quality is light, when combustion chamber draft is run; a large amount of ash content is carried by flue gas and enters discharge flue; at flue gas waste heat recovery system, the position being furnished with heat exchanger tube as energy-saving appliance etc. produces accumulation, affects flue gas circulation; heat-transfer effect lowers; afterbody exhaust gas temperature is higher etc., directly blocks the flue gas heat exchange passage in energy-saving appliance, cause steam generator system disorderly closedown time serious.Boiler is normally run, just means that cleaning cycle is short, generally every other month, must thorough deashing, guarantee flue gas is smooth and easy, avoids pressure combustion, affects boiler and normally runs.For traditional energy-saving appliance structure, each deashing must allow boiler stop 2 ~ 3 days, after exhaust gases passes cooling, flue after boiler of sending someone enters, and carry out labor cleaning, labour intensity is large, operating environment is poor, in addition, because locus is limited, be awkward, and longitudinally can only clear up, not reach the optimum efficiency of cleaning.
Utility model content
In order to solve prior art Problems existing, the utility model provides a kind of biomass boiler energy-saving appliance of easy access.
In order to realize above object, the technical scheme that the utility model is taked is: a kind of biomass boiler energy-saving appliance, comprise energy-saving appliance body, energy-saving appliance body has the sidewall stretched out without heat exchange bend pipe, sidewall offers maintenance aperture, described maintenance aperture is provided with can the access door that is rotationally connected of relatively described sidewall.
According to one preferred embodiment, outwards have the holder that extended structure is formed around described maintenance aperture, the inner side of described holder is provided with circular step, and described circular step has step surface.
According to one preferred embodiment, described access door also comprises door panel structure, the sealing lobe that described door panel structure comprises door-plate and is wholely set with door-plate, described sealing lobe has sealing surface, the described step surface of described sealing surface and described circular step cooperatively interacts, and forms the hermetically-sealed construction of access door.
According to one preferred embodiment, described extended structure extended distance is identical with the gross thickness of the insulation construction outside described energy-saving appliance body.
According to one preferred embodiment, arrange gasket seal between described sealing surface and the described step surface of described circular step, described gasket seal is selected from metallic gasket, asbestos yarn.
According to one preferred embodiment, described holder is also fixedly installed at least four equally distributed connecting bolts, the described door-plate of described door panel structure is provided with the U-lag adapted with described connecting bolt, what described connecting bolt was corresponding snaps in described U-lag, and applies pretightning force by nut end of door plate.
Biomass boiler energy-saving appliance of the present utility model mainly comprises following advantage:
Prior art arranges bigbore maintenance flange and maintenance baffle plate usually on air inlet linkage section top, because the machining angle of bigbore maintenance flange and maintenance baffle plate is difficult to ensure, maintenance flange is forbidden with the contraposition of the bolt hole of maintenance baffle plate, and set bolt is various, cause dismounting loaded down with trivial details, adopt energy-saving appliance access door structure of the present utility model can save bigbore maintenance flange and maintenance baffle plate, reduce workload.
Have at energy-saving appliance body on the sidewall stretched out without heat exchange bend pipe and arrange holder, this holder has reinforcement effect to energy-saving appliance sidewall, eliminates and arrange the reinforcement structures such as ribs on energy-saving appliance sidewall, saves cost.
Access door in the utility model belongs to quick operating valve, opens and closes convenient and swift, simple to operate, effectively can improve overhaul efficiency, shortens the repair time, ensures that steam generator system normally runs.

Detailed description of the invention
Below with reference to accompanying drawings embodiment of the present utility model is described in detail.
Fig. 2 is structural representation of the present utility model.Energy-saving appliance body 1 is arranged on boiler exhaust gas passage, its top is provided with air inlet Connectivity Section 2, bottom is provided with communicating exhaust gas section 4, described communicating exhaust gas section 4 is directly placed on cement pedestal, described energy-saving appliance body 1 is played a supportive role, access hole 5 is arranged on the sidewall of described communicating exhaust gas section 4, is convenient to place clearly and is deposited in dust stratification in described communicating exhaust gas section 4.Described energy-saving appliance body has the sidewall 3 stretched out without heat exchange bend pipe, and described sidewall 3 is provided with access door 6, and described access door adopts hinged mode to be arranged on described sidewall 3, makes the relatively described sidewall of described access door rotatable.
