Integrated low-carbon micro-discharge energy-saving and emission-reduction boiler system

Abstract

The invention discloses an integrated low-carbon micro-discharge energy-saving and emission-reduction boiler system. The system comprises a boiler body (1), a steam drum (2), a heat exchanger (3), a preheater (4), an economizer (5), a superheater (6), a steam turbine (7), a generator (8), a secondary smoke combustion device (9), a desulfuration and dust collect unit (10), an air blower (11) and a smoke exhauster (13), wherein the steam drum (2) and the heat exchanger (3) constitute a hot-water heating circulation loop, the economizer (5) is connected with the steam drum (2), and the air blower (11) feeds air to the preheater (4); the steam drum (2) is connected with the superheater (6), and then connected with the steam turbine (7) by a superheated steam pipe (22); the steam turbine (7) is connected with a low-pressure steam pipe (23), and the generator (8) is linked with the steam turbine (7); and the outlet of a gas duct of the boiler body (1) is connected with a smoke pipe (25), and the smoke exhauster (13) is arranged on the smoke pipe (25), and sequentially feeds smoke into the secondary smoke combustion device (9) and the desulfuration and dust collect unit (10) so as to process and discharge the smoke.

Description

technical field [0001] The invention relates to an integrated system of low-carbon micro-emission energy-saving and emission-reduction boilers. Background technique [0002] As an important thermal energy equipment, boilers are widely used in many industrial and civil fields. Because it burns coal and other fuels, the pollution of carbon dioxide and sulfur dioxide caused by its emissions has become a problem in the field of environmental protection. The current large boilers need to be discharged at high altitudes through chimneys to reduce pollution to living spaces. Chimneys not only affect the overall health of the city It is beautiful and wastes precious land resources; in addition, the high-temperature flue gas after boiler combustion is directly discharged, which not only wastes a lot of heat energy, causes energy waste, but also brings thermal pollution to the environment, so the issue of boiler energy saving is also very important; at present However, there is no in...

Because it burns coal and other fuels, the pollution of carbon dioxide and sulfur dioxide caused by its emissions has become a problem in the field of environmental protection. The current large boilers need to be discharged at high altitudes through chimneys to reduce pollution to living spaces. Chimneys not only affect the overall health of the city It is beautiful and wastes precious land resources; in addition, the high-temperature flue gas directly discharged after boiler combustion not only wastes a lot of heat energy, causes energy waste, but also brings thermal pollution to the environment, so the issue of boiler energy saving is also very important; at present , there is no integrated system for secondary combustion of flue gas discharged after boiler combustion
