Description

Spin upside down formula domestic heating boiler

Technical field

The utility model is related to a kind of civilian heating service equipment, especially a kind of civil boiler for warming.

Background technology

Civil boiler generally existing energy utilization rate is low at present, temperature drift when flue gas emission, and the heat of flue gas is without most That changes greatly is just discharged out of the furnace by boiler absorption, and the consumption and waste of fuel, daily requirement is caused repeatedly to add fuel, be extremely difficult to Lasting heating in 24 hours.

Utility model content

In order to overcome in existing boiler technology, coal burning is insufficient, boiler internal endotherm area is insufficient, energy utilization rate Particulate matter is more in waste, and the tail gas of discharge caused by relatively low, tail gas heat quantity exhaust temperature high heat absorbs not exclusively makes At air pollution the defects of, the utility model spins upside down formula internal structure using a kind of twin furnace multi-pipeline, improves Temperature in burner hearth increases endotherm area in stove, and exhaust pipe is once again set up heat absorption device, adequately absorbs burning in stove The heat of generation improves boiler energy utilization rate, while burning particles object recovery room is arranged, and reduces in final discharge gas Grain waste, reduces air pollution.

Technical solution adopted by the utility model to solve its technical problems is：One kind spinning upside down formula twin-furnace boiler, Boiler body is double wall (being water layer between double wall), and front furnace and rear hearth, the smoke evacuation of furnace body external connection bilayer are divided into furnace body Pipeline (in layer plus water cycle).The smoke-box of front and back burner hearth is communicated in stove internal upper part, and front furnace top is smoke-box, and two are set in smoke-box Vertical water pipe is connected respectively at the top plate of front furnace with middle part, and front furnace lower part is combustion chamber, and chamber front end is filling door, Combustion chamber lower part is that the water pipes of more arrangements are used as comb furnace bottom, comb furnace bottom lower part equipped with primary combustion blast pipe, once into Air hose lower part is combustion waste room, and combustion chamber top is equipped with second-time burning blast pipe, and two blast pipes pass through threeway outside furnace body It is connected with fan；Rear hearth is entirely smoke-box, the water pipes of more vertical arrangements is inside set, at the top of the top of water pipe and rear hearth Double wall is connected, and lower part is communicated with more horizontal water tubes in rear hearth, and horizontal water tube is communicated with rear hearth lower sides, rear hearth Lower end is particle waste recovery room, the particulate matter to settle down in recovered flue gas, the combustion waste room of this recovery room and front furnace There is mobilizable baffle to be separated by, while being connected again by 90 ° of elbows with the double-deck smoke discharging pipe outside furnace body；Front and back burner hearth cigarette Room communicates on the top of intermediate bulkhead；Smoke discharging pipe outside furnace body is also double wall (being water layer in wall), lower end and furnace body Water layer communicate, participate in the water cycle in boiler, meanwhile, at the top of smoke exhaust pipe installation draw cigarette fan, auxiliary inner tube smoke discharge. It is hot water outlet at the top of front furnace, smoke discharging pipe water layer top is cold-water return entrance, overall structure boiler internal water cycle.Stove External wall bottom is equipped with discharge outlet and safe valve opening.

It is above-mentioned to spin upside down formula twin-furnace boiler, water layer, front furnace internal upper part water pipe, the combustion chamber lower parallel of furnace body wall The water layer of the vertical and horizontal water pipe of water pipe, rear hearth and smoke discharging pipe communicates, and constitutes water cycle in stove.

It is above-mentioned to spin upside down formula twin-furnace boiler, the heat smoke that combustion chambers burn fuel generates, into front furnace top Smoke-box, then enters rear hearth by the associated channel of front and back burner hearth, and the relatively cold flue gas for then having exchanged heat is deposited to particle Waste recovery room, then be discharged from smoke discharging pipe, such flue gas just experienced the path spun upside down, make its heat in stove and water Sufficient exchange is obtained, only flue-gas temperature just can be discharged into smoke exhaust pipe downwards after lowering from particle waste recovery room Road, at the same the water in smoke discharging pipe wall due to temperature it is very low, and can absorb again discharge flue gas heat, to reach flue gas Heat fully absorbs utilization, promotes the temperature in burner hearth to the greatest extent.

It is above-mentioned to spin upside down formula twin-furnace boiler, it opens a dirt clean-up port in the outer wall of rear hearth and leads to rear hearth cigarette Room facilitates the later stage to check and clear up the dirt inside rear hearth；One small-power fan of installation carries out pipe at the top of smoke discharging pipe Road draws cigarette, assists the discharge of flue gas.

The utility model has the beneficial effects that the utility model, which spins upside down formula heating boiler, uses front and back burner hearth, multitube The internal structure in road expands endotherm area, and smoke exhaust pipe simultaneously participates in the whole water cycle of boiler, the flue gas of coal burning By furnace body wall and everywhere, the water layer in duct wall is adequately absorbed heat.And the dirt clean-up port of pot chamber design, It can open at any time and boiler internal is cleared up, effectively prevent gas unsmooth flowing caused by boiler blocks.
