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, is the auxiliary combustion equipment for stove and accessory secondary air distribution.

Background technology

Northern China cold in winter, especially in rural area, due to the most scattered settlement of peasant household, be difficult to realize central heating, and peasant household is because considering economic factor mostly, domestic heating stove fuel is chosen the kind that the ature of coal such as brown coal, bituminous coal is comparatively general mostly, and some peasant household gathers materials on the spot, use the living beings such as bavin standing grain, plant stem as fuel, these fuel need air distribution combustion-supporting mostly.Common heating stove is generally only provided with air distribution one time, though or be provided with secondary air distribution, because of secondary air distribution deficiency or air distribution unreasonable, cause fuel combustion incomplete, the thermal efficiency is low, thereby discharge volume of smoke causes provincialism environmental pollution and energy waste.

Summary of the invention

The invention provides a kind of built-in catch cyclone firing wind dish, combustion-supporting for stove and accessory being carried out to secondary air distribution, solve the shortcomings such as the existing combustion stove thermal efficiency is lower, flue dust is large, fuel consumption is many.

The built-in catch cyclone firing of the present invention wind dish, comprise annular wind chamber, described annular wind chamber is provided with the air inlet of connecting fan, annular Feng Qiang center port is poly-burner, in the chamber in described annular wind chamber, be provided with the multiple tilting catch tilting to same direction, each tilting catch is spaced and is fixedly connected on by even circumferential on the inner ring facade in annular wind chamber, and the inner ring facade in described annular wind chamber has and the multiple airing holes that gather burner and communicate.

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

Described cover assembly is pegged graft and is connected with the centre bore 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 is corresponding setting one by one with tilting catch.

In each tilting catch in described annular wind chamber, taking just to tangent air inlet as the first catch, all the other are arranged in order to end position 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 1/2 of annular wind chamber width, and position, end catch width is 4/5 length of annular wind chamber width.

Aperture 4mm～the 7mm of described airing hole.

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

It is suitable for reading that this cyclone firing wind dish is placed in stove and accessory; by this wind dish, burner hearth top (in poly-burner) allocated into uniform rotary wind; whirlwind impels inner flue gas of the stove rise and gather to poly-burner; the air that flue gas is allocated at poly-burner and airing hole is evenly obtained by mixing fully to burn; obviously improve fuel and burn efficiency and thermal efficiency of stoves; soot emissions are reduced; even taking living beings or colm as fuel; also can reach the object of clean burning, effective utilization and the environmental protection of resource are played a positive role.This wind dish adopts cap member and chassis combination, simple in structure, making and easy for installation.

In figure, 1-cover assembly, 1-1-inner ring facade, 2-catch, 2-1-the first catch, position, 2-n-end catch, 3-airing hole, 4-poly-burner, 5-chassis, 6-air inlet, 7-annular wind chamber.

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 accompanying drawing.

See Fig. 1, this wind dish comprises that the center port in annular wind chamber 7 is poly-burner 4 by cover assembly 1 and the annular wind chamber 7 that fastening forms mutually, chassis 5, and the air inlet 6 in annular wind chamber 7 is set to tangential air intake.Chassis 5 has formed annular bottom surface and the outer ring facade in annular wind chamber 7, and cover assembly 1 has formed annular top surface and the inner ring facade 1-1 in annular wind chamber 7.Referring to Fig. 1 and 2, multiple tilting catch 2 stationary arrangement are a side (" chamber " is here annular wind chamber 7, and outside the chamber of inner ring facade 1-1, a 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 and the multiple airing holes 3 that gather burner 4 and communicate.

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 position, end catch 2-n, the radial width of each tilting catch 2 increases by turn, just the radial width of the first catch 2-1 to air inlet 6 only has 1/2 of annular wind chamber 7 width, and the radial width of position, end catch 2-n is 4/5 of annular wind chamber 7 width.And each tilting catch 2 is 50 °～70 ° angles with the bottom surface in annular wind chamber 7, is 30 °～50 ° angles with the tangent plane in annular wind chamber 7.Annular wind chamber 7 inner ring facade 1-1 offer the airing hole 3 that a circle communicates with poly-burner 8, each airing hole 3 and the corresponding setting one by one of each tilting catch 2, the aperture 4mm～7mm of airing hole 3.Poly-burner 8 diameter 100mm～140mm, height 30mm～50mm.

When the blower fan that is connected to air inlet 6 is during to the 7 interior air blast of annular wind chamber, air tangentially enters in chamber from annular wind chamber 7, in the time that air-flow meets to position, end catch 2-n with the first catch 2-1 successively, because of the guide effect of the each tilting catch 2 in annular wind chamber 7 to air-flow, air-flow 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 the poly-interior formation rotary wind of burner 4.

When use, this cyclone firing wind dish is placed in the suitable for reading of stove and accessory, in burner hearth, combustible is lighted rear generation flue gas and flare, now start blower fan (agitating into Secondary Air), wind dish gathers the interior generation rotary wind of burner 4, flue gas in burner hearth and flame accelerate the poly-burner 4 to top under powerful rotary wind effect to be assembled, and fully mixes with the air of constantly allocating in poly-burner 4, and flare fiercely burns into rotation flame upwards.Due to the reasonable wind distribution of cyclone firing wind dish, make burning of coal more complete, the flue gas of discharge is more clean.
