Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

As shown in Figures 1 to 5, the utility model provides an environmentally friendly and energy-saving furnace, which is composed of a furnace body 1 and a chimney 2, and the furnace body 1 and the chimney 2 are connected through a flue 3. A support 9 is also provided at the rear end of the furnace body 1 , and the two ends of the support 9 are respectively connected with the outer wall of the furnace body 1 and the bottom of the chimney 2 . The furnace body 1 is composed of a furnace hearth 4, a hearth 5 and a combustion chamber (not shown in the figure), an air inlet 6 and an ash hopper 7. The upper side of the ash hopper 7, therefore, the burning material in the furnace can directly fall into the ash hopper, which is also convenient for cleaning. A grate 13 is also provided between the combustion chamber and the ash hopper, and the combustibles can be placed on the grate for burning. An air inlet 6 is arranged on the outer wall of the combustion chamber, and the amount of air flow entering the combustion chamber is controlled by opening and closing the air inlet. Since the air inlet is set at the relative position of the smoke exhaust port, the airflow introduced by the air inlet can be directly blown into the smoke exhaust port, so that the dust and smoke in the combustion chamber can be quickly introduced into the smoke exhaust port. The air flow can also promote more complete combustion of the combustibles in the combustion chamber.

Also be provided with the water tank 11 of cylindrical structure in furnace 4, this water tank is arranged on the upper side of combustion chamber, is also distributed with a plurality of water tank through holes 12 on water tank 11, and combustion chamber is arranged on furnace side wall through water tank through hole. The smoke outlet 8 on the top forms a smoke passage. Since the exhaust port is connected with the flue, the dust and smoke generated in the combustion chamber are introduced into the flue through the through hole of the water tank and the exhaust port. Since the dust and flue gas generated in the combustion chamber has a certain amount of heat, the dust and flue gas will also heat the inside of the water tank while passing through the through hole of the water tank, thereby improving the heating efficiency of the water tank. Since the bottom of the water tank is heated when the combustion chamber in the combustion chamber burns, a plurality of water tank through holes are arranged on the water tank to increase the heating surface of the water tank. In addition, the exhaust area can also be reduced through a plurality of through holes of the water tank, which is conducive to drafting and promoting the combustion of the flame in the combustion chamber.

The chimney 2 is composed of a chimney outer wall 14 and a chimney liner 15 , the chimney liner 15 is arranged inside the chimney outer wall 14 , and a hollow area is also provided between the chimney outer wall 14 and the chimney liner 15 . A plurality of smoke exhaust channels 16 are also provided on the chimney liner 15 , and the smoke exhaust channels 16 run through the inside of the chimney liner 15 and are distributed on the chimney liner 15 from top to bottom. The top of the chimney liner 14 outer wall is also wound with a multilayer water pipe 17, and the top of the water pipe 17 extends to the outside of the chimney outer wall 14 and is connected with the external water delivery device, and its end is connected with the water tank through the flue and the smoke outlet. An interval (not shown in the figure) is also provided between adjacent two layers of water pipes. The smoke exhaust channel is set between two adjacent water pipes. The dust and smoke enter any one of the smoke exhaust channels from the space between the two water pipes, and then are discharged from the other end of the smoke exhaust channel to enter any one above it. in the smoke exhaust duct. The two adjacent smoke exhaust channels are arranged in the chimney liner at a certain angle. The advantage is that the dust and smoke are subjected to certain resistance during the rising process, thereby increasing the water pipes wound on the outer wall of the chimney liner. heating time. After the external water delivery device injects water into the water pipe, when the water flows into the water tank, the water in the water pipe can be heated once under the action of the smoke exhaust channel and dust and smoke, and then, when the water in the water pipe flows into the water tank , and the combustion material will be burned in the combustion chamber for secondary heating, which not only shortens the heating time of water but also improves the utilization rate of heat.

Since an outlet pipe (not shown) connected to the water tank is also provided on the outer wall of the furnace body 1, the water after secondary heating can be discharged through the outlet pipe. Because the water in the water pipe and the water tank will not be in contact with the dust and fumes, the harmful substances in the dust and fumes will not be contained and can be used for washing one's face or taking a bath.

Since the bottom of the chimney 2 is also provided with a dust collection tube 10 of a cylindrical structure, the large particles that may be contained in the dust flue gas that may not be completely burned will fall in the dust collection tube, so that the large particles are collected and processed. use. In addition, setting the dust collection cylinder to the same cylindrical structure as the chimney is also more conducive to the collection of large particles.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
