Abstract

The utility model relates to a rotating boiler comprising an outer cylinder and a liner, and a water storing cavity is arranged between the outer cylinder and the liner; the liner comprises a burning chamber and a smoke chamber which are communicated by fire tubes which are arranged on the same periphery at intervals; and the fire tubes are obliquely arranged into a spiral shape. The oblique angles of the fire tubes are 5 to 45 degrees. The burning chamber and the smoke chamber are respectively and internally provided with at least two water circulating pipelines, the at least two ends of which are communicated with the water-storing cavity. In the rotating boiler, as all the fire tubes are obliquely arranged, and all the fire tubes are obliquely arranged into the spiral shape, thus lengthening the length of the fire tubes, reducing the flow speed of the smoke in the fire tubes and leading the high-temperature smoke to be capable of carrying out heat exchange with water for longer time in the fire tubes; and the heat of the high-temperature smoke is fully absorbed, the heat efficiency is higher, the temperature increase of the boiler is faster, and the energy-saving effect is better. Simultaneously, the smoke is sprayed from the fire tubes which are arranged into the spiral shape, so as to lead the smoke in the burning chamber to form vortex, enhance the fuel in the burning chamber to be fully burnt and save energy.

Description

A kind of combusting boiler that revolves

Technical field

The utility model relates to a kind of boiler.

Background technology

The internal structure of existing boiler has very big difference because of exhaust gases passes and water circulation system different, at present, common boiler generally comprises urceolus and inner bag, it between urceolus and the inner bag water storage cavity, water inlet and delivery port are arranged on the urceolus, inner bag comprises combustion chamber and smoke-box, is communicated with by some vertical fire tubes that are intervally arranged on same circumference between combustion chamber and the smoke-box, and smoke-box is in communication with the outside by smoke discharging pipe.This boiler in use, flue gas in the combustion chamber enters smoke-box by fire tube, discharges outside the urceolus, on the path of flow of flue gas by smoke discharging pipe again, flue gas carries out heat exchange by the wall body and the water in the water storage cavity of combustion chamber and fire tube, combustion chamber, thereby water is heated.In the said structure, because fire tube is vertical state (for vertical boiler) or be the level of state (for horizontal boiler) is provided with, flue gas flows to smoke-box from the combustion chamber along rectilinear direction, the flow velocity of flue gas in fire tube is very fast, in addition under the constant situation of mutual alignments such as combustion chamber and smoke-box and physical dimension, the length of fire tube is the shortest, high-temperature flue gas can to carry out the path of heat exchange the shortest with water, short with the time of water heat exchange, make the heat of high-temperature flue gas fully do not absorbed and just be discharged from outside the boiler that cause the thermal efficiency lower, not only boiler heating is slow by water, and form waste, be unfavorable for energy-conservation.

The utility model content

The purpose of this utility model provide the abundant heat exchange of a kind of energy, the thermal efficiency higher revolve combusting boiler.

For achieving the above object, the utility model adopts following technical scheme: a kind of combusting boiler that revolves, comprise urceolus and inner bag, it between urceolus and the inner bag water storage cavity, inner bag comprises combustion chamber and smoke-box, be communicated with all fire tube oblique arrangement spirality by the fire tube that is intervally arranged on same circumference between combustion chamber and the smoke-box.

The angle that described fire tube tilts is 5-45 °.

The angle that described fire tube tilts is 10-30 °.

The angle that described fire tube tilts is 15 °.

All arrange in described combustion chamber and the smoke-box and be provided with the water circulating pipe that at least two two ends are communicated with water storage cavity.

In the utility model, because each fire tube is obliquely installed, all fire tube oblique arrangement spirality, not only fire tube length is prolonged, and reduced the flow velocity of flue gas in fire tube, and make high-temperature flue gas in fire tube, can have long time and water to carry out heat exchange, the heat of high-temperature flue gas is fully absorbed, the thermal efficiency is higher, the boiler temperature rise is fast, and energy-saving effect is better; Simultaneously, flue gas sprays from the fire tube of helical pattern, can make the flue gas in the combustion chamber form eddy current, impel the full combustion of fuel in the combustion chamber, saved the energy, the high-temperature flue gas in the combustion chamber has also relatively evenly guaranteed that flue-gas temperature is basic identical in each fire tube simultaneously, help each orientation uniform heat exchange in the boiler, evenly heat up.In addition, the utility model has increased heat exchange area after in combustion chamber and smoke-box water circulating pipe being set, and is convenient to the preheating of water and further heating, has made full use of heat energy, has promoted the circulation of water in the water storage cavity simultaneously, helps absorbing heat fast and heating up.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Design of the present utility model both can be applied to vertical boiler, also can be applied to horizontal boiler.Only listed the applicable cases in vertical boiler in the present embodiment, see shown in Figure 1, revolve combusting boiler among this figure, comprise base 5, urceolus 1 and inner bag, it between urceolus 1 and the inner bag water storage cavity 17, inner bag comprises combustion chamber 3 and smoke-box 15, all arranges in combustion chamber 3 and the smoke-box 15 and is provided with the

water circulating pipe

2 and 16 that three two ends are communicated with water storage cavity, and smoke-box 15 is provided with the smoke discharging pipe 12 that is in communication with the outside; Be communicated with by the fire tube 9 that is intervally arranged on same circumference between combustion chamber and the smoke-box, combustion chamber 3, fire tube 9, smoke-box 15 have constituted smoke flow channels jointly with smoke discharging pipe 12; The same end of above-mentioned each fire tube 9 rotates identical angle in the same way along described circumferencial direction, makes that fire tube 9 is inclined, all fire tube oblique arrangement spirality.In the specific implementation, the angle of inclination of fire tube 9 is selected as the case may be, and the inclination angle can be in 5-45 ° of scope, and the inclination angle is in 10-30 ° of scope the time, and fuel combustion speed and endothermic effect are relatively good, and inclination angle effect in the time of 15 ° reaches best.The quantity of the water circulating pipe 16 in the water circulating pipe 2 in the above-mentioned combustion chamber and the smoke-box 15 can be according to actual conditions and different.Among Fig. 1,4 is water inlet, and 6 is slag notch, and 7 are the cinder notch of living, and 8 is coal filling hole, and 10 is cleaning door, and 11 are the bathing hot water apparatus, and 13 is atmosphere connection port, and 14 is delivery port.

When the utility model is used in horizontal boiler, basic identical with vertical boiler, only be on syndeton, to change a little to get final product in conjunction with the characteristics of horizontal boiler, no longer exemplify in the present embodiment.
