Abstract
Provided is a boiler with a multiple return strokes thread smoke tube. The boiler with the multiple return strokes thread smoke tube comprises a boiler body and a boiler flue. The boiler with a multiple return strokes thread smoke tube is characterized in that the boiler flue (2) is arranged inside the boiler body (1), a main chamber (3) is arranged at the bottom inside the boiler flue (2), and a plurality of heat absorbing slices (4) are arranged inside the main chamber (3). A high temperature area (6) is arranged at the top inside the boiler flue (3), a back gas duct (5) is arranged between the high temperature area (6) and the main chamber (3) to connect the high temperature area (6) and the main chamber (3). Convective heat transfer can be achieved after smoke causing a vortex in the thread smoke tube, and produced heat which can be fully absorbed by boiler water outside the smoke tube is capable of prolonging heat absorbing time of the boiler water and reducing the smoke discharge temperature. Due to a plurality of heat absorbing slices in the main chamber, heating area of the boiler body and heat absorbing area of the boiler water are expanded, and thermal efficiency of the boiler is increased. The boiler with a multiple return strokes thread smoke tube has the advantages of being relatively high in heat exchange efficiency, low in energy consumption, full in heating in the boiler body, low in waste discharge and convenient to operate and maintain.
Description
Technical field
The utility model relates to heating equipment, relates in particular to a kind of boiler with many backhauls smoke pipe.
Background technology
Boiler is a kind of energy conversion, to the energy of boiler input the forms such as heat energy of chemical energy in the fuel, electric energy, high-temperature flue gas are arranged, and through the boiler conversion, outwards output has steam, high-temperature water or the organic heat carrier of certain heat energy.The original meaning of pot refers to the water container that heats at fire, and stove refers to the place of combustion fuel, and boiler comprises pot and stove two large divisions.The hot water that produces in the boiler or steam can be directly for industrial production and people's lives provide required heat energy, also can be converted to mechanical energy by Steam Power Equipment, or by generator mechanical energy is converted to electric energy again.Provide the boiler of hot water to be called hot-water boiler, be mainly used in life, a small amount of application is also arranged in the industrial production.The boiler that produces steam is called steam boiler, and is often referred to as boiler, multiplex in thermal power station, boats and ships, locomotive and industrial and mining enterprises.
Various problems usually appears in conventional boiler in practical process, for example water is heated in the process in to stove, and the heat conduction is abundant not, causes inefficiency, and energy consumption improves.The waste gas that produces in the process of stove fuel combustion and soot emissions have all caused great pollution to air quality and surrounding enviroment in air.The shortcomings such as the poor efficiency that conventional boiler shows, high energy consumption, high pollution can't satisfy growing industry production needs already.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of higher thermal energy exchange efficiency that has, energy consumption is lower, be heated in the stove fully, the boiler with many return threads that waste discharge is less, comprise body of heater, flue, main chamber, heat absorbing sheet, the rear portion flue, the high-temperature region, the two return threaded flue, three return threads, device for absorbing tail gas, desulfurization dust-removal system, preheating can, the scrubbing mouth, the ash disposal mouth, automatic fire banking-up board, it is characterized in that described body of heater inside is provided with flue, the bottom is provided with main chamber in the flue, above-mentioned main chamber inside is provided with the multiple tracks heat absorbing sheet, described flue internal upper part is provided with the high-temperature region, be provided with the rear portion flue that is connected the two between this high-temperature region and main chamber, the high-temperature region is connected with the two return threaded flue, described two return threaded flue connects three return threads, this three return thread is connected with device for absorbing tail gas, described device for absorbing tail gas is connected with main chamber and desulfurization dust-removal system respectively, the middle on the lower position of described body of heater is provided with some scrubbing mouths and ash disposal mouth, upper of furnace body is provided with automatic fire banking-up board, and the outside described device for absorbing tail gas of this boiler is connected with preheating can.
The beneficial effects of the utility model are: flue gas produces eddy flow in threaded flue, realizes convection heat transfer' heat-transfer by convection, and the heat of its generation can fully be absorbed by the boiler water of smoke pipe outside, has prolonged the stove water heat absorption time, has reduced exhaust gas temperature.The design of the inner multiple tracks heat absorbing sheet of main chamber has namely increased the body of heater heating surface area, has increased again stove water endotherm area, has improved the thermal efficiency of boiler.The device for absorbing tail gas of body of heater outer setting, preheating can and desulfurization dust-removal system have further reduced flue-gas temperature, have purified flue gas, have reduced concentration, have realized final dusting.The setting of a plurality of scrubbing mouths and ash disposal mouth makes the regular maintenance of boiler simpler, easy to maintenance.On the control technology of boiler, used the Full-automatic microcomputer thermostatic control technology, coal combustion is more stable, and leaving water temperature can be according to actual user demand regulation and control.Whole boiler has higher thermal can exchange efficiency, energy consumption is lower, be heated fully in the stove, waste discharge is less, simple to operate, easy to maintenance.
