Abstract
Description
Technical Field
[0001] This utility model relates to the field of boiler technology, and in particular to an oil / gas condensing steam boiler. Background Technology
[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water, or organic heat carriers with a certain amount of thermal energy. The original meaning of "boiler" refers to a water-filled container heated over a fire, while "furnace" refers to the place where fuel is burned. A boiler consists of two main parts: the boiler and the furnace. The hot water or steam produced in a boiler can directly provide the heat energy needed for industrial production and daily life. It can also be converted into mechanical energy through a steam power unit, or further converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers, mainly used for domestic purposes, with some applications in industrial production. Boilers that produce steam are called steam boilers, often simply referred to as boilers, and are mostly used in thermal power plants, ships, locomotives, and industrial and mining enterprises. Condensing boilers utilize efficient flue gas condensation waste heat recovery devices to absorb the sensible heat of the boiler exhaust and the latent heat released by the condensation of water steam, thereby improving the boiler's thermal efficiency.
[0003] The existing Chinese patent with publication number CN208365508U discloses a condensing steam boiler. The existing technical solution described above has the following defects: Although the hot air in the furnace enters the flue pipe after passing through the combustion chamber, and the hot air flows out of the flue pipe and enters the flue gas outlet pipe, and the flue gas flows out from the outlet of the flue gas pipe, heat exchange occurs with the water in the heat exchange chamber during the flue gas flow, preheating the water entering the inner cavity of the boiler and avoiding the waste of heat in the flue gas, the above technical solution cannot filter the flue gas after it is used. As a result, impurities and dust in the flue gas are emitted into the air along with the flue gas, which can easily pollute the surrounding environment and reduce its environmental friendliness.

[0016] Compared with the prior art, the present invention provides an oil / gas condensing steam boiler, which has the following beneficial effects:
[0017] (1) In this utility model, the flue gas generated by the condensing steam boiler body during operation enters the condenser through the conveying pipe. After being condensed by the condenser, the flue gas enters the filter box through the connecting pipe. By using the filter screen in the filter box, impurities and dust in the flue gas can be filtered, preventing impurities and dust in the flue gas from being emitted into the air together, thereby protecting the surrounding environment and improving the environmental protection of this equipment.

By opening the baffle on the ash discharge pipe, the dust cleaned off the filter screen can enter the collection box through the use of the ash discharge pipe, preventing the cleaned dust and impurities from accumulating on the filter screen and causing blockage, thus facilitating its subsequent normal use.

When the condensing steam boiler body 1 is working, the flue gas generated enters the condenser 2 through the conveying pipe 3. After being condensed by the condenser 2, the flue gas enters the filter box 6 through the connecting pipe 8. By using the filter screen 7 in the filter box 6, impurities and dust in the flue gas can be filtered, preventing impurities and dust in the flue gas from being emitted into the air together, thereby protecting the surrounding environment and improving the environmental friendliness of the equipment. By turning on the motor 14 on the bottom surface of the filter box 6, the motor 14 drives the rotating rod 9 to rotate, causing the cleaning brush 10 on the rotating rod 9 to rotate, which can automatically clean the impurities and dust on the filter screen 7, preventing impurities and dust from accumulating on the filter screen 7 and causing blockage, thus facilitating its normal subsequent use and improving its practicality.
[0029] In one embodiment, the interior of the filter box 6 is provided with an inclined partition 24 below the filter screen 7, passing through the rotating rod 9. The top surface of the partition 24 is provided with a through hole. The partition 24 can guide the cleaned dust to enter the collection box 13 through the ash discharge pipe 12, thereby collecting the cleaned impurities and dust.

[0030] In one embodiment, air inlets are provided on both sides of the bottom surface of the filter box 6, and the use of the air inlets and the exhaust pipe 5 allows for air circulation.
[0031] In one embodiment, a baffle 11 is provided through one side of the top surface of the ash discharge pipe 12, and the baffle 11 is movably connected to the ash discharge pipe 12. By pulling out the baffle 11, impurities and dust in the ash discharge pipe 12 can enter the collection box 13.
[0032] In one embodiment, the front surface of the collection box 13 is provided with a door 23, and the door 23 is hinged to the collection box 13 by a hinge, wherein the dust in the collection box 13 can be cleaned by opening the door 23.

By turning on the motor 14 on the bottom surface of the filter box 6, the motor 14 drives the rotating rod 9 to rotate, which causes the cleaning brush 10 on the rotating rod 9 to rotate, thereby automatically cleaning the impurities and dust on the filter screen 7, preventing impurities and dust from accumulating on the filter screen 7 and causing blockage, thus facilitating its normal subsequent use.
[0036] In one embodiment, the control circuit of the control panel can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.
[0037] Working principle:
[0038] During operation, the flue gas generated by the condensing steam boiler body 1 enters the condenser 2 through the conveying pipe 3. After condensation by the condenser 2, the flue gas enters the filter box 6 through the connecting pipe 8. The filter screen 7 in the filter box 6 filters impurities and dust from the flue gas, preventing them from being released into the air and thus protecting the surrounding environment and improving the environmental friendliness of the equipment. By turning on the motor 14 on the bottom surface of the filter box 6, the motor 14 drives the rotating rod 9 to rotate, causing the cleaning brush 10 on the rotating rod 9 to rotate, automatically cleaning impurities and dust from the filter screen 7, preventing accumulation and clogging, and thus facilitating cleaning. Its subsequent normal use is conducive to improving its practicality. When the rotating rod 9 rotates, it drives the first gear 17 on the rotating rod 9 to rotate. When the first gear 17 rotates, it drives the second gear 20 on the connecting rod 19 to rotate, so that the fan blade 18 on the connecting rod 19 rotates. This agitates the flue gas in the filter box 6, allowing larger impurities in the flue gas to be quickly separated from the flue gas, thereby improving the filtration effect of the flue gas. By opening the baffle 11 on the ash discharge pipe 12, the dust cleaned from the filter screen 7 can enter the collection box 13 through the use of the ash discharge pipe 12, preventing the dust and impurities after cleaning from accumulating on the filter screen 7 and causing blockage, thus facilitating its subsequent normal use.
