Description

A kind of construction is novel, high-efficiency environment friendly hot air boiler

Technical field:

The present invention relates to boiler more particularly to a kind of thermal efficiency height, dustless environment protecting hot air boiler.

Background technique:

Currently, kind, cultivation greenhouse majority are heated using hot water and steam boiler, make heat-conduction medium with water, heating is slow, heat Amount loss is big, waste water resource.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 shortcomings that current existing hot air boiler various degrees and deficiency, 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.

Summary of the invention:

The purpose of the present invention, is to provide that a kind of construction is novel, high-efficiency environment friendly hot air boiler, smoke combustion turn back path length, Interlayer 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 scheme is that a kind of construction is 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 2 and furnace body intraformational bed 3.Before furnace body, Afterwards, it is equipped with the first lateral partitions 23 in right side outside sandwich 2, the outside sandwich 2 of forward and backward, right three side is divided into two parts up and down, furnace body Left side outside sandwich 2 ' does not set lateral partitions, transparent.The first lateral partitions 23 of outside sandwich 2 furnace shell thereon on the right side of the furnace body 1 is equipped with inlet of cold air 25, its lower furnace shell 1 of the first lateral partitions 23 is equipped with a heated air outlet 27, primary heated Air outlet slit connects blower 28, and 28 exhaust outlet of blower connects a heated air import 29 of furnace body intraformational bed 3.In furnace body inner clip It is equipped with the first vertical baffle 20 between smoke exhaust pipe 16 is turned back in the end of layer 3 and middle part is turned back smoke exhaust pipe 14, top is connected to the The bottom surface of two smoke boxes 15, intraformational bed 3 or so connection of second smoke box 15 with 19 top of third smoke box thereon.It turns back smoke evacuation in middle part The second vertical baffle 21 is equipped between pipe 12 and the vertical smoke exhaust pipe 10 of roof of the furnace, second vertical baffle the upper end connects furnace roof portion Intraformational bed inner wall, lower end connect furnace wall on the right side of burner hearth.The second lateral partitions 36 are equipped in the front side of burner hearth top surface and left side, by The heated air that heated air import 29 enters intraformational bed 3 will enter around the top of third smoke box 19 and the second smoke box 15 Between first vertical baffle 20 and the second vertical baffle 21, then detour along burner hearth antetheca and left side wall to burner hearth rear wall, furnace Thorax rear wall which is provided with the first up and down port 38.It is on rear side of the roof of the furnace thereon bottom surface perimeter of the first smoke box 11 and left Side is equipped with third lateral partitions 24, and there are the second up and down ports 39 for front side.Heated air around to burner hearth rear wall passes through First up and down port 38 rises, is then horizontally through between vertical 10 hole of smoke exhaust pipe of roof of the furnace to the second up and down of front side Port 39, then returned in third lateral partitions 24 thereon through the second up and down port 39.Corresponding first smoke box, 11 top surface thereon, pass through Furnace body outside sandwich 2 is equipped with hot-blast outlet 31, returns in the hot wind thereon of third lateral partitions 24 through 31 outlet hot wind supply of hot-blast outlet.

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

Furnace body of the present invention is equipped with outside sandwich and intraformational bed, and the first lateral partitions, outer clip on the left of furnace body are equipped in the middle part of outside sandwich Layer does not set lateral partitions, upper and lower connection.Cold air is introduced into partition outside sandwich thereon, through left side connection outside sandwich enter partition it Lower outside sandwich, cold air are once heated, and are discharged by outlet by blower, and enter furnace body intraformational bed simultaneously.Burner hearth erects It is wrapped in intraformational bed to smoke exhaust pipe, the first smoke box, smoke exhaust pipe of turning back, the second third smoke box, and their outer surface is all provided with There is radiating fin.Intraformational bed is respectively equipped with the first and second vertical baffles, makes into above and below the once heated air of intraformational bed Detour is turned 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, there are upper and lower for rear side Connection mouth.Third lateral partitions are equipped in the rear of the first smoke box bottom surface position, the second from left side, there are up and down ports for front side.One It will be outside burner hearth front side wall, left side wall around on rear side of burner hearth, then after at secondary heated air circuitous flow to burner hearth external right side wall Side up and down port rises, and then on front side of the gap being horizontally through between vertical smoke exhaust pipe 10 to furnace roof, then again by front side Second line of a couplet port is turned back to the top of third lateral partitions, is most discharged thereon, across the hot wind of outside sandwich through the first smoke box of furnace roof afterwards Hot wind supplies are discharged in mouth 31.As it can be seen that enter intraformational bed by once heated air in furnace body outside sandwich, pass sequentially through it is longitudinal every Plate, lateral partitions are repeatedly turned back, multiple detour is heated again, give absorption cmpletely to burner hearth heat and smoke exhaust pipe waste heat, The thermal efficiency is high, energy conservation and environmental protection.
