Description

The square energy-efficient hot-water boiler of the anti-burning of secondary

1, technical field

The utility model relates to a kind of hot-water boiler, and especially a kind of thermal efficiency height, energy-conservation and good environmental protection, good looking appearance, practical novel secondary be anti-to burn square energy-efficient hot-water boiler.

2, background technology

Making in the society at present and use in hot-water boiler many kinds are arranged, though that the kind that has in the hot-water boiler of these kinds has is energy-conservation, the thermal efficiency is higher and the characteristics of environmental protection, but because of its technical scheme difference separately, the effect of its energy-conservation thermal efficiency and environmental protection is different, simultaneously also in various degree have an outmoded defective of profile.

3, summary of the invention

Task of the present utility model is to provide that a kind of energy-saving effect is obvious, the thermal efficiency is high, good environmental protection, novel secondary aesthetic in appearance are anti-burns square energy-saving efficient boiler.

Task of the present utility model realizes with following technical scheme, take at the end that is provided with the dust collection chamber that has cleaning door and to be located in the shell body that has heat-insulation layer, arranged outside at shell body has decorative panel, in the shell body of the upside of dust collection chamber, be provided with inner housing, and make between its inner housing and the shell body and form storage tank, be disposed with the delivery port that is connected with storage tank outside on the housing sidewall, water inlet, downside at inner housing is positioned with lower fire grating, be provided with an end hollow upper fire-grating that the other end is connected with the scrubbing mouth that is connected with storage tank on the top of lower fire grating, and make between lower fire grating and the upper fire-grating and form lower combustion chamber, be provided with the following horizontal water pipe perpendicular in the upper fire-grating upper inner with upper fire-grating, upside at the horizontal water pipe of this time is provided with the following vertical water pipe perpendicular with it and makes its this time horizontal, vertically form upper combustion chamber between water pipe and the upper fire-grating, shell body corresponding to lower combustion chamber is provided with except that cinder notch, shell body corresponding to upper combustion chamber is provided with coal filling hole, top and inboard in upper combustion chamber are provided with firebreak, following vertical water pipe top be provided with orthogonal and be connected with aqua storage tank on laterally water pipe and on vertical water pipe, the upper end of inner housing is a cone-shaped fume collecting chamber, and the top of fume collecting chamber is connected with smoke exhaust pipe.The new described inner and outer shell of this practicality is square and the shell body front panel is a trapezoidal shape, and shell body is provided with decorative panel, and the upper end of shell body is provided with the normal pressure mouth that is connected with aqua storage tank and is provided with the sight burner corresponding to the shell body of horizontal water tube down.

The course of work of the present utility model is as follows, earlier water inlet is connected with the water source, water will be filled with in the storage tank, and with delivery port be connected with water end (W.E.), add coal and light by coal filling hole, the coal that lighted this moment carries out primary combustion, its heat energy is by upper fire-grating and last, thereby following task of water being heated to the water realization in the storage tank thermal energy conduction to water pipe in length and breadth, the coal of process after burning on the upper fire-grating falls into and carry out second-time burning on the lower fire grating in lower combustion chamber, its heat energy reaches by upper fire-grating, water pipe conducts to the water in the storage tank in length and breadth down, thereby realize task to the water heating, gas fume after burning enters flue by fume collecting chamber and discharges, water after the heating is sent by delivery port, water in its boiler is constantly replenished by water inlet, sewage draining exit, see burner, dust collection chamber, the normal pressure mouth, the scrubbing mouth is identical with function in the existing boiler.

Owing to taked technique scheme, the beneficial effects of the utility model: the one, owing to adopted the technical scheme of second-time burning, sufficient combustion, thermal efficiency height, energy-saving effect are clear and definite, the characteristics of good environmental protection so have; The 2nd, because upper fire-grating is the blank pipe that is connected with storage tank, and it establishes above the combustion chamber the crisscross water pipe that is connected with storage tank is completely arranged, thus can realize effectively absorbing heat energy, thus the high task of the realization thermal efficiency; The 3rd, owing to adopted square shell structure and its front panel to adopt trapezium structure and shell to be provided with the technical scheme of decorative panel, so and the characteristics of good looking appearance are arranged, can effectively realize task of the present utility model in sum.
