Environment-friendly coal-fired boiler uniform in heating

Abstract

The invention discloses an environment-friendly coal-fired boiler uniform in heating. The environment-friendly coal-fired boiler comprises a combustion tower, a water tank body, a partition plate, through holes, a feeding port and a dust removing device. The combustion tower is arranged on the inner side of the water tank body in a penetrating manner. The partition plate is arranged on the part, below the water tank body, in the combustion tower and provided with the multiple through holes. The feeding port is formed in the part, between the water tank body and the partition plate, of the side portion of the combustion tower. The upper end of the combustion tower communicates with the dust removing device. The dust removing device comprises an air inlet pipe, a dust tank, a baffle, a spring, a discharging port, a sprayer and an exhausting pipe. One end of the air inlet pipe communicates with the upper end of the combustion tower, and the other end of the air inlet pipe communicates with the upper portion of the dust tank. The interior of the dust tank is provided with the oblique baffle in a sliding manner. Compared with the prior art, the heating balance of the boiler can be improved, the labor intensity of workers is reduced, the dust discharging amount of the boiler is reduced, and energy consumption is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of boilers, in particular to a coal-fired boiler with uniform heating and environmental protection. 【Background technique】 [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers...

AI Technical Summary

Problems solved by technology

Boilers that generate steam are called steam boilers, often referred to as boilers for short, and are mostly used in thermal power stations, ships, locomotives, and industrial and mining enterprises. The combustion chambers of existing coal-fired boilers are usually set at the bottom of the water tank body, and the fuel generated in the combustion chambers It is difficult to heat the water in the water tank body in a balanced manner. Usually, the water in the lower part of the water tank body has boiled and the water temperature in the upper part is not high. In addition, the design of the combustion chamber of the existing coal-fired boiler is not reasonable enough, resulting in coal Insufficient combustion, the carbon slag in the combustion chamber is difficult to clean, and the existing coal-fired boilers will emit a large amount of dust when burning coal, causing air pollution
