Description

Built-in catch cyclone firing wind dish

Technical field

The present invention relates to a kind of built-in catch cyclone firing wind dish, be the auxiliary combustion equipment for stove secondary air distribution.

Background technology

Northern China is cold for winter, especially in rural area, due to the most scattered settlement of peasant household, it is difficult to central heating, and peasant household is because in view of economic factor, the kind that the ature of coal such as brown coal, bituminous coal is the most general chosen mostly by domestic heating stove fuel mostly, some peasant household then gathers materials on the spot, using the living beings such as bavin standing grain, plant stem as fuel, these fuel need air distribution combustion-supporting mostly.Common heating stove is typically provided only with an air distribution, though or be provided with secondary air distribution, but because secondary air distribution is not enough or air distribution is unreasonable, cause fuel combustion incomplete, the thermal efficiency is low, thus discharges volume of smoke, causes provincialism environmental pollution and energy waste.

Summary of the invention

The present invention provides a kind of built-in catch cyclone firing wind dish, combustion-supporting for stove carries out secondary air distribution, solves the shortcomings such as the existing combustion stove thermal efficiency is relatively low, flue dust is relatively big, fuel consumption is many.

The present invention built-in catch cyclone firing wind dish, including annular wind chamber, described annular wind chamber is provided with the air inlet of connecting fan, the center port in annular wind chamber is poly-burner, it is provided with, in the chamber in described annular wind chamber, the multiple tilting catch tilted to same direction, each tilting catch circumferentially uniform intervals arranges and is fixedly connected on the inner ring facade in annular wind chamber, and the inner ring facade in described annular wind chamber has the multiple airing holes communicated with poly-burner.

Described annular wind chamber is combined by cover assembly and chassis, described chassis constitutes annular bottom surface and the outer ring facade in annular wind chamber in annular wind chamber, described cover assembly constitutes annular top surface and the inner ring facade in annular wind chamber in annular wind chamber, and each tilting catch stationary arrangement is on the inner ring facade of cover assembly.

Described cover assembly is connected with the centre bore grafting of the annular bottom surface on chassis with inner ring facade lower end.

The air inlet in described annular wind chamber is tangential air intake.

Described airing hole and tilting catch are that one_to_one corresponding is arranged.

In each tilting catch in described annular wind chamber, with just to tangent air inlet for the first catch, remaining is arranged in order to position, end catch by the whirlwind direction of tangential air intake；From the first catch to position, end catch, the radial width of each tilting catch is cumulative.

Described the first catch radial width is the 1/2 of annular wind chamber width, and position, end catch width is 4/5 length of annular wind chamber width.

Aperture 4mm～7mm of described airing hole.

Described each tilting catch is 30 °～50 ° with the inclination angle of the tangential plane of annular wind chamber inner ring, and the inclination angle, bottom surface with annular wind chamber is 50 °～70 ° simultaneously.

It is suitable for reading that this cyclone firing wind dish is placed in stove; uniform rotary wind is allocated to above burner hearth into (in the most poly-burner) by this wind dish; whirlwind promotes inner flue gas of the stove rise and gather to poly-burner; flue gas is uniformly obtained by mixing with fully burning at the air that poly-burner and airing hole are allocated into; significantly improve fuel and burn efficiency and thermal efficiency of stoves; reduce soot emissions; even if with living beings or colm as fuel; also can reach the purpose of cleaning burning, effectively utilization and environmental protection to resource play a positive role.This wind dish uses cap member to combine with chassis, and simple in construction makes and easy for installation.

Accompanying drawing explanation

Fig. 1 is the structural representation of built-in catch cyclone firing wind dish.

Fig. 2 is the vertical view part sectioned view of Fig. 1.

In figure, 1 cover assembly, 1-1 inner ring facade, 2 catch, 2-1 first place catch, position, 2-n end catch, 3 airing holes, 4 poly-burners, 5 chassis, 6 air inlets, 7 annular wind chambeies.

Detailed description of the invention

The example structure of the built-in catch cyclone firing wind dish that accompanying drawing represents, is described further below in conjunction with the accompanying drawings.

Seeing that Fig. 1, this wind dish include mutually being fastened the annular wind chamber 7 formed by cover assembly 1 and chassis 5, the center port in annular wind chamber 7 is poly-burner 4, and the air inlet 6 in annular wind chamber 7 is set to tangential air intake.Chassis 5 constitutes annular bottom surface and the outer ring facade in annular wind chamber 7, and cover assembly 1 constitutes annular top surface and the inner ring facade 1-1 in annular wind chamber 7.Seeing Fig. 1 and 2, multiple tilting catch 2 stationary arrangement are side (" chamber " here is annular wind chamber 7, and outside the chamber of inner ring facade 1-1, side is poly-burner 4) in the chamber of inner ring facade 1-1.The inner ring facade 1-1 in annular wind chamber 7 has the multiple airing holes 3 communicated with poly-burner 4.

See Fig. 2, each tilting catch 2 is by the tangential air intake direction in annular wind chamber 7, the first catch 2-1 is arranged in order to end position catch 2-n, the radial width of each tilting catch 2 increases by turn, the just radial width to the first catch 2-1 of air inlet 6 only has the 1/2 of annular wind chamber 7 width, and the radial width of end position catch 2-n is the 4/5 of annular wind chamber 7 width.Further, each tilting catch 2 is 50 °～70 ° of angles with the bottom surface in annular wind chamber 7, is 30 °～50 ° of angles with the tangent plane in annular wind chamber 7.Annular wind chamber 7 inner ring facade 1-1 offers the airing hole 3 that a circle communicates with poly-burner 4, and each airing hole 3 is arranged with each tilting catch 2 one_to_one corresponding, aperture 4mm～7mm of airing hole 3.Poly-burner 4 diameter 100mm～140mm, highly 30mm～50mm.

When being connected to blower fan air blast in annular wind chamber 7 of air inlet 6, air enters in chamber from the tangential of annular wind chamber 7, when air-flow meets with the first catch 2-1 to end position catch 2-n successively, because of the guide effect to air-flow of each tilting catch 2 in annular wind chamber 7, air-flow i.e. can be along the windward side of each tilting catch 2, import corresponding airing hole 3 with same tangential tilt, be blown in poly-burner 4 from each airing hole 3, thus in poly-burner 4, form rotary wind.

During use, this cyclone firing wind dish is placed in the suitable for reading of stove, flue gas and flare is produced after combustible is lighted in burner hearth, now start blower fan (agitating into Secondary Air), rotary wind is produced in the poly-burner of wind dish 4, flue gas and flame in burner hearth accelerate the poly-burner 4 to top under powerful rotary wind effect and assemble, and are sufficiently mixed with the air constantly allocated in poly-burner 4, and flare the most fiercely burns into the flame rotated upwards.Due to the reasonable wind distribution of cyclone firing wind dish, making burning of coal more complete, the flue gas of discharge more cleans.
