Description

Novel high-efficiency environment friendly hot air boiler

Technical field:

The utility model relates to boiler more particularly to a kind of novel high-efficiency environment friendly hot air boilers.

Background technique:

Currently, kind, cultivation greenhouse majority are heated using hot water or steam boiler, heat-conduction medium is done with water, heating is slow, heat Amount loss is big, waste water resource, and hot air boiler is then using air as heat-conduction medium, and easy to operate, safety coefficient is high, uses the longevity Life length, saves water resource, and the kind aquaculture for being particularly suitable for lacking in water resource area is promoted the use of.

The defect and deficiency of current existing hot air boiler various degrees, the structure that most hot air boilers use is furnace Thorax connects smoke exhaust pipe as heat source, and heated air interlayer, i.e., simple fire tube, interlayer knot is arranged around burner hearth and smoke exhaust pipe Structure, air heats are bloated by blower in interlayer, to providing heat source in greenhouse.Simple structure, flame travel are short in furnace, cause the energy Failing to be fully utilized and just discharge out of the furnace, high fume temperature, fuel combustion is insufficient, and efficiency of combustion is low, and UTILIZATION OF VESIDUAL HEAT IN is insufficient, Energy consumption is high, and smoke contamination is big, and use cost is high.

Utility model content:

The purpose of the utility model, is to provide a kind of novel high-efficiency environment friendly hot air boiler, and smoke combustion is turned back path length, folder Layer heating surface area is big, detour is long in length and breadth for heated scoring path, and burning is abundant, heat exchange is abundant, and the thermal efficiency is high, energy-efficient.

The technical solution of the utility model is a kind of novel high-efficiency environment friendly hot air boiler, including furnace shell 1, burner hearth 4, furnace Grate 5, coal filling hole 6, decoking mouth 7, cleaning door 8, smoke exhaust pipe of turning back, chimney 35, burner hearth secondary air inlet 32, ash-falling chamber's Secondary Air into Mouth 33, inlet of cold air 25, hot-blast outlet 31, characterized in that there is furnace body outside sandwich and furnace body inner clip 3.Forward and backward in furnace body, It is equipped with the first lateral partitions 23 in the first outside sandwich of right side 2, the first outside sandwich 2 of forward and backward, right three side is divided into two up and down Point, the interior lateral partitions, transparent of not setting of the second outside sandwich 2 ' on the left of furnace body.The first of the first outside sandwich 2 is horizontal on the right side of furnace body It is equipped with inlet of cold air 25 to the furnace shell 1 of partition 23 thereon, its lower furnace shell 1 of the first lateral partitions 23 is equipped with primary heated Air outlet slit 27, a heated air outlet connection blower 28,28 exhaust outlet of blower connect the primary heated sky of furnace body intraformational bed 3 Gas import 29.In the third of furnace body intraformational bed 3 turn back smoke exhaust pipe 16 and second turn back be equipped between smoke exhaust pipe 14 first vertically every Plate 20, top are connected to the bottom surface of the second smoke box 15, and the second smoke box 15 and the intraformational bed 3 of 19 top of third smoke box thereon are left Right connection.It turns back in middle part first and is equipped with the second vertical baffle 21 between smoke exhaust pipe 12 and the vertical smoke exhaust pipe 10 of roof of the furnace, the Two vertical baffle the upper ends connect furnace roof portion intraformational bed inner wall, and lower end connects furnace wall on the right side of burner hearth, on front side of the burner hearth top surface and Left side is equipped with the second lateral partitions 36, and the heated air that You Yici heated air import 29 enters intraformational bed 3 will bypass third cigarette The top of case 19 and the second smoke box 15 enters between the first vertical baffle 20 and the second vertical baffle 21, then along burner hearth antetheca and Left side wall detours to burner hearth rear wall, and burner hearth rear wall which is provided with the first up and down port 38, in roof of the furnace thereon first On rear side of the bottom surface perimeter of smoke box 11 and left side is equipped with third lateral partitions 24, front side there are the second up and down port 39, around Heated air to burner hearth rear wall is risen by the first up and down port 38, is then horizontally through the vertical smoke evacuation of roof of the furnace To front side the second up and down port 39 between 10 hole of pipe, then return in third lateral partitions 24 thereon through the second up and down port.It is right It answers 11 top surface of the first smoke box to be equipped with hot-blast outlet 31 thereon, across furnace body outside sandwich 2, returns the heat thereon in third lateral partitions 24 Wind through 31 outlet hot wind supply of hot-blast outlet,

Caused by the utility model the utility model has the advantages that

The utility model furnace body is equipped with outside sandwich and intraformational bed, and the first lateral partitions, furnace body left side are equipped in the middle part of outside sandwich Side outside sandwich does not set lateral partitions, transparent.Cold air is introduced into partition outside sandwich thereon, enters through left side connection outside sandwich Outside sandwich under partition, cold air are once heated, and are discharged by outlet by blower, and enter outer clip under partition simultaneously Layer.Burner hearth, vertical smoke exhaust pipe, the first smoke box, smoke exhaust pipe of turning back, the second third smoke box are included in intraformational bed, and they Outer surface is equipped with radiating fin, and intraformational bed is respectively equipped with the first and second vertical baffles, makes into the primary heated of intraformational bed Air up and down detour turn back in burner hearth.And and before the position of burner hearth top surface, the second from left side be equipped with the second lateral partitions, thereafter There are up and down ports for side.Third lateral partitions are equipped in the rear of the first smoke box bottom surface position, the second from left side, there are upper and lower for front side Connection mouth.It once will be outside burner hearth front side wall, left side wall around to burner hearth at heated air circuitous flow to burner hearth external right side wall Rear side rises through rear side up and down port.And then be horizontally through on front side of the gap between vertical smoke exhaust pipe 10 to furnace roof, then Front side up and down port is turned back to the top of third lateral partitions, most afterwards through the first smoke box of furnace roof thereon, across the heat of outside sandwich Hot wind supply is discharged in wind outlet 31.It can be seen that.Intraformational bed is heated by once heated air in furnace body outside sandwich, is passed sequentially through vertical To partition, lateral partitions, repeatedly turn back, multiple detour is heated again, burner hearth heat and smoke exhaust pipe waste heat are given cmpletely It absorbs, the thermal efficiency is high, energy conservation and environmental protection.
