Description

Superconduction reflection atmospheric energy-saving vertical boiler

The utility model relates to a kind of life atmospheric vertical boiler.

Existing life is made of the pot furnace outside-lining, the inner bag that have fire door, entery and delivery port with the atmospheric vertical boiler, and inner bag courage chamber constitutes the pyrotechnics chamber of boiler, and the chamber that outer courage and inner bag surround constitutes the hot-water cavity that adds of boiler.Add hot-water cavity have horizontally set, up and down be misplaced arrangement heating water pipe, heated the pyrotechnics chamber that water pipe passes boiler.The smoke exhaust pipe of boiler is passed by the pyrotechnics top of chamber and adds the hot-water cavity upper chamber and stretched out outside the stove by outer courage top, the coal-fired high temperature cigarette that produces, fire conduct heat water heating in the pot with radiation and convection type by pyrotechnics chamber wall during boiler operatiopn, rise to pass by cigarette, internal heat stream simultaneously and heat in the process that the water pipe gap enters smoke exhaust pipe water heating in the stove.The weak point of existing stove and accessory is that cigarette, internal heat stream flow process are short, with heated water pipe, wall short exchange heat time of contact in pyrotechnics chamber is insufficient, the loss of exhaust gas temperature high heat is big, the thermal efficiency of boiler is low, coal consumption was big when boiler operatiopn was used.Moreover, heating the water pipe horizontal cross places, many no water treatment facilities when boiler operatiopn is used in addition, the incrusted deposit that heating produces sticks in pipe and forms scale crust on the tube wall, because scale crust heat transfer property extreme difference, happened occasionally so heat the phenomenon (being usually said booster phenomenon) that water pipe burnt down.

The purpose of this utility model is improved with the atmospheric vertical boiler existing life, a kind of cigarette, internal heat stream long flow path are provided, and heat absorption is abundant, complete, thermal efficiency height, coal consumption is few, can very fast superconduction reflection atmospheric energy-saving vertical boiler with water heating in the stove.

Superconduction reflection atmospheric energy-saving vertical boiler by the outer courage that has fire door, entery and delivery port, be loaded on inner bag in the outer courage, be positioned at the inner bag bottom fire grate, be positioned at the inner bag below and constitute with the ash-storing bin that flue integral body is connected, inner bag courage chamber constitutes the pyrotechnics chamber of boiler, and the chamber that outer courage and inner bag surround constitutes the hot-water cavity that adds of boiler.Contiguous grate place, bottom, pyrotechnics chamber is equipped with the refraction arch wall of reflection cigarette, internal heat stream, reflect the arch wall upper support, be fixed with the barrier wall that cross section is an arc, seal between barrier wall two side ends and pyrotechnics chamber side wall surface, the barrier wall is divided into " ∩ " type fireworks channel with the pyrotechnics chamber.The fireworks channel bottom that barrier wall and pyrotechnics chamber wall surround is provided with exhanst gas outlet, exhanst gas outlet is connected with the smoke evacuation chimney of boiler, add in the annular compartment of hot-water cavity and radially be distributed with superconduction heat transfer element (being usually said heat pipe), superconduction heat transfer element concentric circles is arranged, be misplaced mutually, superconduction heat transfer element bottom is passed pyrotechnics chamber wall and is stretched in the pyrotechnics chamber.The annular bottom wall face that adds hot-water cavity is recessed curved wall, and the whole blowdown connection head that connects is arranged on the arcuate bottom wall, discharges out of the furnace so that will add the foreign material and the incrustation scale of deposition in the hot-water cavity.

Superconduction reflection atmospheric energy-saving vertical boiler adds the superconduction heat transfer element quantity that is provided with in the annular compartment of hot-water cavity can be according to the production capacity and the instructions for use decision of boiler, being generally radially distributes arranges 1-6 row by concentric circles, is misplaced each other between the superconduction heat transfer element.

In order to make heat that stove and accessory produces fire coal fully, absorb fully, further reduce exhaust gas temperature to reduce thermal loss to greatest extent, and reduce the pollution of smoke evacuation to environment, between the exhanst gas outlet of superconduction reflection atmospheric energy-saving vertical boiler and smoke evacuation chimney the dedusting economizer is housed.

Economizer is the standpipe jacket type structure, interior pipe is exhaust gases passes, the outer tube sleeve dress on inner pipe, upper and lowerly bind, constitute the heating water jacket between inner and outer pipes, outer tube is provided with entery and delivery port, the superconduction heat transfer element is circumferentially arranged among the heating water jacket, and superconduction heat transfer element bottom is passed the inner tubal wall face and is stretched in the exhaust gases passes.The economizer lower end is connected with the smoke catching tank seal that has water injection pipe and blow-off pipe, and economizer exhaust gases passes lower port is communicated with smoke catching water tank case chamber.

According to concrete instructions for use, economizer and boiler can be distinguished independent water filling and outside heat supply water, also economizer heating water jacket and boiler can be added hot-water cavity and utilize pipeline to be communicated with by the water notes of economizer with preheating to be added in the boiler.

Superconduction reflection atmospheric energy-saving vertical boiler pyrotechnics chamber makes the pyrotechnics chamber form " ∩ " type fireworks channel by the barrier wall is set, cigarette, internal heat stream flow process have been increased, cigarette, the time of staying of internal heat stream in stove have been prolonged, thereby can fully carry out heat exchange, secondly can be rapidly the heat of high temperature cigarette, fire be transmitted to by superconduction heat transfer element of being provided with and adds in the hot-water cavity, so can very fast water in the stove be heated by hot heat transfer and heat conduction during boiler work operation.It is low that boiler is equipped with the waste heat recovery exhaust gas temperature of dedusting economizer in further will discharging fume, and further reduced thermal loss, so the thermal efficiency height of boiler.By the smoke catching water tank, the dust arrestment that is contained in the smoke evacuation is got off, thereby reduced the pollution of smoke evacuation environment.

Accompanying drawing is an embodiment of the present utility model, and the utility model is not limited only to embodiment, further specifies the utility model below in conjunction with embodiment.
