Abstract

The utility model relates to a double-water jacket reversely-combusting smokeless non-pressure tea boiler. The utility model is composed of a water boiler shell body, a base seat, a sealing bottom, an internal sleeve, a sealing head, a boiler door, a double-layer fire grate, etc. The utility model is characterized in that the interior of the boiler forms a double-water jacket structure; a U-shaped smoke and flame passage is formed between two water jackets; the upper part of the combustion chamber is provided with two symmetric U-shaped water press plates. The smoke and the flame in the boiler pass from an S-shaped smoke and flame passage to a chimney, and then the smoke and the flame are exhausted out of the boiler. The utility model has the advantages of combustion enlargement, long retention time of the smoke and the fume in the boiler, heating surface enlargement, sufficient heat exchange, high heat efficiency, reversely-combusting method combustion, no smoke, and no environmental pollution.

Description

Double water jacket counter-burning type high effective smokeless pressureless tea boiler

The utility model is the improvement to drinking water boiler, relates to a kind of multiduty double water jacket counter-burning type high effective smokeless pressureless tea boilers such as heating, bathing, confession drinking hot water, steamed rice that can be used for.

At present, the design form that domestic drinking water boiler is produced is more, and its structure is divided into individual layer fire grate combustion in right direction drinking water boiler usually and double-layer grate is passed combustion formula drinking water boiler; It is less that double-layer grate is passed the combustion chamber of combustion formula drinking water boiler, and design is in a side of drinking water boiler main body, and it is slow to heat up when having burning, and burning velocity is slow, and has influenced the thermal efficiency of drinking water boiler, also has single backhaul flue, and the drinking water boiler heating surface is little, and the thermal efficiency is low.

The utility model has overcome above-mentioned weak point, provide a kind of energy-conservation, pollution-free, the thermal efficiency is high, multiduty double water jacket counter-burning type high effective smokeless pressureless tea boiler, can be widely used in industrial and mineral, enterprises and institutions, organ, army, hospital, institute and rural area.

The utility model double water jacket counter-burning type high effective smokeless pressureless tea boiler content Description:

The utility model double water jacket counter-burning type high effective smokeless pressureless tea boiler is made up of drinking water boiler housing, base, back cover, interior cover, blowing pipeline, hand hole, end socket, fire door, water pipe furnace grate, lower fire grating, Hui Men, chimney etc., it is characterized in that: form ring-shaped water jacket in the middle of drinking water boiler housing and interior cover and the lower water jacket baffle plate, constitute the double water jacket structure with the ＂ U ＂ shape water jacket above the water pipe furnace grate, the space of ＂ U ＂ shape water jacket is the combustion chamber, forms ＂ U ＂ shape smoke flue between double water jacket; Be a fiery chamber shrouding above the combustion chamber, prevent that the pyrotechnics in the combustion chamber from rising, make drinking water boiler form the counter-burning type burning; The ＂ U ＂ shape banking fire plate that two symmetries are arranged on the shrouding of fiery chamber becomes with welded steel plate, and ＂ U ＂ shape banking fire plate makes the interior pyrotechnics of stove be discharged out of the furnace by chimney by ＂ S ＂ shape smoke flue route again; In stove, be provided with the blowing pipeline, can deliver to the combustion chamber by hair-dryer mechanical air supply top blast.

The utility model double water jacket counter-burning type high effective smokeless pressureless tea boiler, adopt ＂ U ＂ shape combustion chamber to enlarge combustion chamber, double water jacket structure and ＂ S ＂ shape smoke flue in the stove, pyrotechnics holdup time in stove is increased, enlarged heating surface, heat exchange is abundant, thermal efficiency height can reach 74% through the test proof thermal efficiency; Adopt the anti-burning mode double-layer grate structure of burning, coal-fired and fuel gas fully burns, smokelessly, non-environmental-pollution, less than 1 grade, smoke discharge amount is less than 0.02kg/h through environmental protection test soot emissions lingemann blackness.

Embodiment:

Fig. 1 is a double water jacket counter-burning type high effective smokeless pressureless tea boiler structural representation.

See Fig. 1, the utility model double water jacket counter-burning type high effective smokeless pressureless tea boiler is a back cover 2 on drinking water boiler base 1, back cover 2 is provided with lower fire grating 16, form a ring-shaped water jacket in the middle of drinking water boiler housing 4 and interior cover 5 and the lower water jacket baffle plate 3, constitute the double water jacket structure with the ＂ U ＂ shape water jacket 6 above the water pipe furnace grate 14, the space of ＂ U ＂ shape water jacket 6 is the combustion chamber, coal-fired entering on the inherent water pipe furnace grate 14 of stove by upper furnace door 13 burnt, not clean-burning fire coal is fallen into second-time burning on the lower fire grating 16, improved the thermal efficiency of drinking water boiler, established an ash door 17 at bottom of furnace body and remove ashes.Having formed ＂ U ＂ shape smoke flue between double water jacket, is a fiery chamber shrouding 12 above the combustion chamber, can prevent that the pyrotechnics in the combustion chamber from rising, and makes drinking water boiler form the counter-burning type burning; The ＂ U ＂ shape banking fire plate 8 that two symmetries are arranged on fiery chamber shrouding 12, become with welded steel plate, hair-dryer is delivered in the combustion chamber by blowing pipeline 7 mechanical air supply top blast, pyrotechnics in the stove is through behind the twice combustion, enter in the ＂ U ＂ shape banking fire plate 8, pyrotechnics is by ＂ S ＂ shape smoke flue route, discharge out of the furnace by chimney 10 again, the utility model combustion chamber capacity is big, double water jacket structure and ＂ S ＂ shape smoke flue can make pyrotechnics holdup time in stove increase, enlarged heating surface, heat exchange is abundant, thermal efficiency height.In upper of furnace body is an end socket 11, and the dirt in the stove can be removed by hand hole 9, and is more abundant for making fired coal combustion, places lower furnace door 15 in the bottom of drinking water boiler.
