Abstract

An energy-saving environment-friendly boiler comprises a boiler outer container, an inner container, air chambers, a primary combustion chamber, a secondary combustion chamber, a fire grate 5 and a water cavity, wherein the fire grate is arranged among the combustion chambers and the air chambers, the water cavity is partitioned by a return plate 15 with V-shaped cross section between the inner container and the outer container, row tubes 10 are arranged in the inner container 12 and are communicated with the water cavity partitioned by the return plate 15, a chimney 14 is communicated with a smoke cavity of the inner container, two air chambers 3,4 are parallelly arranged on the bottom of the furnace body by an air baffle 2, the primary combustion chamber and the secondary combustion chamber are partitioned by a smoke baffle 8 on the air chambers, and the smoke baffle 8 communicated with the water cavity partitioned by the return plate is suspended in the secondary combustion chamber 6. By adopting a structure that the primary combustion chamber and the secondary combustion chamber are used for combustion simultaneously and a structure of water seal closed parallel air chambers, water gas can be produced and combustion efficiency is increased. According to actual detection, thermal efficiency reaches over 75%, carbon content of slag is only 6.1% (lower than that of a fire grate in a mechanical layer), and the boiler can save coal which is 1/3 of boilers of the same kind and meet requirements of having high efficiency, saving energy and protecting environments.

Description

Energy-saving, environmental protection boiler

Technical field

The utility model relates to a kind of boiler, and the spy relates to a kind of boiler of energy-conserving and environment-protective.

Background technology

Coal-burning boiler is that a kind of common coal that utilizes provides the device of hot water for people as the energy.The kind of coal-burning boiler is more in the market.As publication number CN 1 490576A, name is called " high-efficiency cryogenic exhausting coal-fired hot-water boiler ", this invention is on the basis of conventional temperature coal-fired hot-water boiler, by being set, the low-temperature energy-saving device realizes improving the purpose of boiler efficiency on back-end ductwork, owing to the low-temperature energy-saving device is set at afterbody, there is no improvement in the burner hearth, fuel fail completing combustion, the thermal efficiency of boiler improve limited and the flue gas of discharging in dustiness and to contain the cigarette amount bigger.Publication number CN 1 71 91 02A, name is called " environmental protection coal-fired hot-water boiler ", this invention comprises combustion chamber, fireworks channel and flue, the combustion chamber has one to go up main chamber and a following auxiliary combustion chamber, have horizontal last fireworks channel and following fireworks channel, of the present utility model owing to adopt two combustion chambers and two flues, ratio of combustion is more abundant, two flues are that laterally revolution utilizes the dust landing, but because flue is that laterally revolution is provided with, the speed of flue gas reduces less relatively, reduce from making dust-laying effect, and the utility model complex structure is unfavorable for promoting.Publication number CN1648546A, name is called " the energy-conservation oil gas coal of a kind of smoke abatement and dust control is used the fuel normal-pressure hot-water boiler more ", comprise horizontal coal-fired chamber and vertical boiler body, horizontal combustion chamber is made up of with the double furnace wall of vertical boiler body overlap joint double furnace wall and is ganged up the water tank that forms boiler mutually, horizontal combustion chamber is divided into bilevel upper combustion chamber and lower combustion chamber and is divided into bilevel upper combustion chamber and lower combustion chamber and places within the bottom of vertical boiler body, though this boiler sufficient combustion, thermal efficiency height, flue dust can be separated with flue gas, but flue is a straight way, being unfavorable for that imperfect combustion composition fully burns also is unfavorable for simultaneously the dust in flue gas landing, and complex structure, the manufacturing cost height.Existing environment-friendly boiler mostly adopts double-layer grate counter-burning type structure, and the one, requirement stoker personnel technical capability height; Because upper grate all is to adopt water pipe to support fuel to burn in the above, easily causes the fouling of water pipe inside and outside, the booster rate is higher, and boiler is short service life.

Summary of the invention

The utility model purpose is to overcome the deficiency that prior art exists, and a kind of dustless and smokeless energy-saving, environmental protection boiler is provided, and has solved that the thermal efficiency is low, dustiness and contain the big technical problem of cigarette amount in the flue gas.Technical problem of the present utility model is achieved through the following technical solutions:

A kind of energy-saving, environmental protection boiler, comprise the outer courage [11] of body of heater, inner bag [12], air compartment, main, subsidiary combustion chamber and be located at the combustion chamber and air compartment between fire grate [5], the water cavity that is divided into by the V-shaped backhaul plate in cross section [15] between inner bag and the outer courage, be provided with tubulation [10] in the inner bag [12], chimney [14] is communicated with the flue gas cavity of inner bag [12], it is characterized in that: bottom of furnace body by wind isolation board [2] spacing parallel arranging an air compartment [4] and two air compartments [3] are set, above the air compartment by being separated with main chamber [7] and subsidiary combustion chamber [6] between smoke baffle plate [8], the outstanding smoke baffle plate [8] that is connected with backhaul plate [15] interval water cavity that is furnished with in subsidiary combustion chamber [6], tubulation [10] is connected with backhaul plate [15] interval water cavity.

Further, smoke baffle plate [8] end face that the utility model is positioned between main chamber [7] and the subsidiary combustion chamber [6] is provided with the many upper hoses that communicate with it [9], upper hose [9] is communicated with backhaul plate [15] the interval water cavity of top, flue gas enters subsidiary combustion chamber by sky between upper hose [9], under the iris action of subsidiary combustion chamber smoke baffle plate [8], flue gas is by upwards the weave throngh gap of inner bag [12] and tubulation [10] of following turning, flue dust lands under the self gravitation effect in the flue gas, the speed of flue gas is in circuitous hurried decline in service, reach cooling dedusting purpose, thereby improve the thermal efficiency.

The utlity model has following advantage:

1, owing to adopts major and minor combustion chamber burning structures form, water seal enclosed air compartment structure arranged side by side simultaneously, can produce water-gas, increased efficiency of combustion greatly, through actual detected, the thermal efficiency reaches more than 75%, boiler slag carbon content only is 6.1% (being lower than mechanical layer burner row), and than similar saving coals from boiler 1/3, this product reaches efficiently, the energy-saving and environmental protection requirement;

2, a typhoon machine is two air compartment air-supplies simultaneously, and air quantity can be regulated at any time;
