A high-efficiency, energy-saving and environment-friendly boiler

Abstract

The invention discloses an efficient energy saving and environmental protection boiler. The efficient energy saving and environmental protection boiler comprises a furnace body, a hot water sleeve, aconveying barrel and a spray barrel. The hot water sleeve is arranged in the furnace body and comprises a box body, a heating cavity and a communicating cavity, and a vertical rotating shaft is fixedly connected with the lower end of an output shaft of a motor. A first helical bevel gear is coaxially arranged on the rotating shaft. The first helical bevel gear is in meshing connection with a second helical bevel gear. The second helical bevel gear is coaxially connected with a blade through a transmission shaft. A scraper is fixed on the rotating shaft. A horizontal spray tube is installed inthe spray barrel. The bottom of the spray barrel communicates with a water tank. According to the efficient energy saving and environmental protection boiler, the heating cavity formed in the hot water sleeve can improve the heating area of the hot water sleeve, increase the contacting area with flame and flue gas, increase the heating area, facilitate interior water to quickly absorb heat for temperature rise, and improve the heat utilization rate; and cold water is sprayed in the spray barrel to absorb heat in the flue gas to purify the flue gas for reducing influence on the surrounding environment.

Description

technical field [0001] The invention relates to environmental protection equipment, in particular to a high-efficiency, energy-saving and environment-friendly boiler. Background technique [0002] Energy has always been an important resource related to my country's economic development and people's lives. At present, my country's energy consumption is growing strongly, the contradiction between supply and demand has further deteriorated, and the task of energy conservation and emission reduction is still arduous. The combustion efficiency of coal combustion equipment in our country is low, which produces a large amount of harmful gases and seriously pollutes the environment. [0003] 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. In the prior art, the old-fashioned s...

Problems solved by technology

In the prior art, the old-fashioned small coal-fired boilers are all arranged with several horizontal water pipes under the cupola of the boiler (the lower end of the cupola is in the center of the furnace), the fire and smoke directly rise from the cupola, and the fire and smoke are in the furnace hall. The residence time is short, and basically rises and runs away in a straight line, which is neither energy-saving nor environmentally friendly, has low thermal efficiency, and seriously pollutes the atmosphere
