Abstract

A reverse flue three-return-stroke water boiler is characterized in that the reverse flue three-return-stroke water boiler comprises a square bent type combustion chamber (1), two-return-stroke smoke exhaust pipelines (2), three-return-stroke smoke exhaust pipelines (3), a front smoke chamber (4) and a back smoke chamber (5), a water inlet pipe is arranged at the bottom of a boiler outer drum, a water outlet pipe is arranged on the upper portion of the boiler, a smoke exhaust pipe is arranged on the top of the boiler and is connected with the back smoke chamber, and a burning machine connector is arranged in the combustion chamber. Due to the fact that the structure of devices inside a water boiler furnace is changed, thermal efficiency of the three-return-stroke smoke exhaust pipelines is given full play, and an existing water boiler is improved to increase the thermal efficiency of the boiler by about 10%.

Description

A kind of reverse flue three backhaul hot-water boilers
Technical field
The utility model relates to the technology of flame smoke evacuation route trend in a kind of combustion gas, the oily water bath body of heater, more particularly, is the combustion chamber and the cigarette line structure renovation technique of a kind of three backhaul wetting back-type combustion gas, oily hot-water boiler.
Background technology
At present, heating boiler commonly used, generally usefulness is three backhaul combustion gas of wetting back-type, oily hot-water boiler, it is a kind of boiler of horizontal body of heater.This horizontal body of heater is a column structure, and the combustion chamber in the body of heater also is a cylindrical structure, the bottommost of its position in the boiler thorax, be provided with the two return smoke discharging pipe on top, combustion chamber, be provided with three backhaul smoke discharging pipes on two return smoke discharging pipe top, and front smoke chamber, devices such as rear smoke chamber.Its operation principle is: after combustion chamber gas injection (oil) burning, the pyrotechnics that produces is along the two return smoke discharging pipe, three backhaul smoke discharging pipes from bottom to top in a clockwise direction in stove motion discharge from the smoke evacuation chamber at last, at this moment, the cold water that enters from the boiler feed water mouth is along with the combustion chamber, the two return smoke discharging pipe, the temperature of device such as three backhaul smoke discharging pipes raises and also progressively raises, the water temperature at the top in boiler also reaches near state with the temperature of three backhaul smoke discharging pipes, therefore, the high temperature of the three backhaul smoke discharging pipes in this time is inoperative to the rising of boiler water temperature, lose heat energy in vain, thereby cause boiler thermal output to reduce.
Summary of the invention
The purpose of this utility model is to solve above-mentioned deficiency, a kind of total structure that neither influences boiler is provided, do not change the mode that goes out on advancing under the boiler Inlet and outlet water yet, can save the energy again and make three backhaul combustion gas of new structure simple, easy for installation, oily hot-water boiler.
Utility model is achieved through the following technical solutions: design a kind of reverse flue three backhaul hot-water boilers, its technical characterictic be in the horizontal boiler thorax, be provided with quarter bend head dummy combustion chamber, two return smoke discharging pipe, three backhaul smoke discharging pipes, front smoke chamber, rear smoke chamber and outside boiler boiler drum bottom be provided with water inlet pipe, the top of boiler is provided with outlet pipe, be provided with smoke exhaust pipe at the top and be connected with rear smoke chamber, the combustion chamber is provided with the combustor interface.
Their correlation is: quarter bend head dummy combustion chamber is located at horizontal middle part in the boiler thorax, its end is connected with the combustor interface, combustion gas or fuel oil enter the combustion chamber by the combustor interface and burn, the other end of combustion chamber, just bend part is connected with the two return smoke discharging pipe.The position of two return smoke discharging pipe is located at the top of combustion chamber, and the one end is connected with the combustion chamber bend part, and the other end is connected with front smoke chamber; Be provided with three backhaul smoke discharging pipes below the combustion chamber, the one end is connected with front smoke chamber, and the other end is connected with rear smoke chamber.Two return smoke discharging pipe and three backhaul smoke discharging pipes all are to be welded to form side by side by some steel pipes are parallel, its quantity how much be that capacity according to boiler decides, the about 1.2-1.5 rice of diameter in the common 1 ton boiler, boiler thorax, the quantity of two, three return duct can be at the 8-12 root.
After starting working in the combustion chamber, the pyrotechnics of combustion chamber enters three backhaul smoke discharging pipes with regard to the easement pipe from two return smoke discharging pipe, front smoke chamber and arrives rear smoke chamber at last and discharge by smoke exhaust pipe.The direction of motion of whole pyrotechnics is an anticlockwise motion, and therefore, we call reverse flue three backhauls to this movement locus phenomenon, thereby has formed the notion of " reverse flue three backhaul hot-water boilers ".
The present invention is owing to changed the structure of device in the water bath burner hearth, three backhaul smoke discharging pipes of present widespread usage are changed into the bottom of combustion chamber from the top of combustion chamber, just three backhaul smoke discharging pipes are installed on the position of the minimum water inlet of boiler thorax inner bottom part, this position also is a low-temperature space in the boiler.It is exactly in order to make three backhaul smoke discharging pipes be in low water temperature district in the boiler thorax that three backhaul smoke discharging pipes are located at herein purpose, with the cold water that enters boiler a temperature difference is arranged, do not have the problem of temperature difference waste heat energy when the boiler thorax inner top position with hot water with regard to having changed three backhaul smoke discharging pipes like this, given full play to the thermal efficiency of three backhaul smoke discharging pipes at boiler thorax inner top.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Reverse flue three backhaul hot-water boilers also are a kind of columniform horizontal boilers, in the horizontal boiler thorax 13 be provided with quarter bend head dummy combustion chamber 1, two return smoke discharging pipe 2, three backhaul smoke discharging pipes 3, front smoke chamber 4, rear smoke chamber 5 and outside boiler drum 6 bottoms be provided with water inlet pipe 7, be provided with outlet pipe 8 above, be provided with smoke exhaust pipe 9 at rear smoke chamber 5 tops, combustion chamber 1 is provided with parts such as combustor interface 10 and combustor 11.
Their correlation is: quarter bend head dummy combustion chamber 1 is located at the middle part of 13 lateral attitudes in the boiler thorax, and its front end is connected with combustor interface 10.The combustion gas of quarter bend head dummy combustor 11 or fuel oil enter quarter bend head dummy combustion chamber 1 by combustor interface 10 and burn and arrive the other end of combustion chamber, and just bend part 12, and bend part 12 is connected with two return smoke discharging pipe 2.The position of two return smoke discharging pipe 2 is located at the top of quarter bend head dummy combustion chamber 1, and the one end is connected with quarter bend head dummy combustion chamber bend part 12, and the other end is connected with front smoke chamber 4; Be provided with three backhaul smoke discharging pipes 3 below quarter bend head dummy combustion chamber 1, the one end is connected with front smoke chamber 3, and the other end is connected with rear smoke chamber 5.The connection of each parts recited above all forms by welding procedure.
