Description
Technical field
The utility model relates to a kind of no flue dust boiler.
Background technology
Existing boiler, generally body of heater, fire grate and fire tube or the water pipe type furnace roof heat exchanger of being fueled mouthful by being provided with of steel constitutes, has the following ashpit that is provided with of positive furnace hearth and fire grate, such stove and accessory, the burning required air enters the stove hall by ashpit through fire grate, carbon monoxide that carbon, imperfect combustion generated that burning is generated and sulfide have little time to burn fully again and just discharge by the furnace roof heat exchanger, thereby the thermal efficiency is low, smoke density is big, such boiler not only environmental pollution is serious, but also because fuel combustion is insufficient, the waste ample resources.
The utility model content
The purpose of this utility model provides a kind of energy-conserving and environment-protective, no flue dust boiler that the thermal efficiency is high, to overcome the deficiency of existing product.
The purpose of this utility model is achieved through the following technical solutions:
A kind of no flue dust boiler, comprise upper furnace body, lower furnace body and desulfurizing dust-collector, the upper furnace body both sides are equipped with the boiler feed water mouth, be provided with burner hearth in the lower furnace body, upper furnace body was communicated with lower furnace body by communicating pipe, the first half of upper furnace body is provided with secondary combustion chamber, and extend outside the upper furnace body hot water outlet upper end, and the hot water outlet end passes secondary combustion chamber and is communicated with lower furnace body.
Described secondary combustion chamber bottom is to having circumferential several layers smoke pipe, each smoke pipe bottom all is communicated with the circumferential cleaning door of upper furnace body outer wall, all be communicated with near the smoke pipe at hot water outlet place with burner hearth, hearth outer wall be provided with some extend to the lower furnace body outside help the oxygen mouth.
Described secondary combustion chamber right-hand member is communicated with economizer, the economizer upper end is provided with delivery port, and the terminal side of economizer is provided with water inlet, and the economizer bottom is communicated with desulfurizing dust-collector, described desulfurizing dust-collector inside is provided with water circulating pump, and the desulfurizing dust-collector upper right is communicated with the air-introduced machine that is positioned at chimney bottom.
The beneficial effects of the utility model are:
1. energy-conservation: heating surface area is big, and the heat absorption backhaul is long, thereby has improved the thermal efficiency of boiler, the thermal efficiency 〉=80%.
2, environmental protection: exhaust gas temperature low (≤80 ℃), smokeless, dustless, no sulphur.
3, it is fast to go out heat: just can go out hot water (40 ℃ to 50 ℃) behind a boiler in 3 to 5 minutes.
4, air-introduced machine adopts frequency control (but stepless speed regulation), thereby reaches the controllable effect of burning velocity, is user-friendly to.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of the described no flue dust boiler of the utility model embodiment.
Among the figure:
1, upper furnace body; 2, lower furnace body; 3, desulfurizing dust-collector; 4, boiler feed water mouth; 5, burner hearth; 6, communicating pipe; 7, secondary combustion chamber; 8, hot water outlet; 9, smoke pipe; 10, cleaning door; 11, help the oxygen mouth; 12, economizer; 13, delivery port; 14, water inlet; 15, water circulating pump; 16, chimney; 17, air-introduced machine.
The specific embodiment
As shown in Figure 1, the described no flue dust boiler of the utility model embodiment, comprise upper furnace body 1, lower furnace body 2 and desulfurizing dust-collector 3, upper furnace body 1 both sides are equipped with boiler feed water mouth 4, be provided with burner hearth 5 in the lower furnace body 2, upper furnace body 1 is by being communicated with lower furnace body 2 communicating pipe 6, and the first half of upper furnace body 1 is provided with secondary combustion chamber 7, extend outside the upper furnace body 1 hot water outlet 8 upper ends, and hot water outlet 8 ends pass secondary combustion chamber 7 and are communicated with lower furnace body 2; Described secondary combustion chamber 7 bottoms are to having circumferential several layers smoke pipe 9, each smoke pipe 9 bottom all is communicated with the circumferential cleaning door 10 of upper furnace body 1 outer wall, all be communicated with near the smoke pipe 9 at hot water outlet 8 places with burner hearth 5, burner hearth 5 outer walls be provided with some extend to lower furnace body 2 outsides help oxygen mouth 11; Described secondary combustion chamber 7 right-hand members are communicated with economizer 12, economizer 12 upper ends are provided with delivery port 13, economizer 12 terminal sides are provided with water inlet 14, economizer 12 bottoms are communicated with desulfurizing dust-collector 3, described desulfurizing dust-collector 3 inside are provided with water circulating pump 15, and desulfurizing dust-collector 3 upper right are communicated with the air-introduced machine 17 that is positioned at chimney 16 bottoms.
Operation principle is: cold water is entered by the water inlet 14 of economizer 12, be connected to boiler feed water mouth 4 from the delivery port 13 of economizer 12, through boiler upper furnace body 1(low-temperature space) heating back is by communicating pipes 6 input boiler lower furnace body 2(high-temperature region) heat, transport to the hot equipment of using by boiler top hot water outlet 8 at last.The pyrotechnics that fuel burns in boiler furnace 5 absorbs heat through three backhauls, after economizer 12 UTILIZATION OF VESIDUAL HEAT IN, pass through desulfurizing dust-collector 3 desulfurization and dedustings again after, but adopt air-introduced machine 17(stepless speed regulation) discharge by chimney 16.
