Environmentally-friendly energy-saving device of boiler

Abstract

The invention provides an environmentally-friendly energy-saving device of a boiler. The device comprises a flue gas pipeline and a heat transfer unit, wherein the lower part of the flue gas pipeline is provided with a flue gas inlet communicated with a boiler flue gas port, and the upper part of the glue gas pipeline is provided with an outlet; the heat transfer unit is arranged on the periphery of the pipe wall of the flue gas pipeline; and between the flue gas inlet and the outlet, a heat insulation expander is arranged in the glue gas pipeline along the direction of gas flow so as to ensure that the cross sectional area of the flue gas pipeline is reduced. The energy-saving device cannot be limited by a site, has simple structure, low cost and easy popularization and greatly improves the energy-saving effect of the boiler.

Description

technical field [0001] The invention relates to an environment-friendly and energy-saving device, in particular to an environment-friendly and energy-saving device for a boiler. Background technique [0002] At present, there are many types of boiler devices, including steam boilers, hot water boilers, etc. The fuel of the boilers can be light oil, heavy oil, natural gas, etc. However, no matter what kind of boiler it is, it will produce high-temperature flue gas emissions, which not only cause a lot of waste of heat energy, but also pollute the environment. For this reason, those skilled in the art have developed various environmental protection and energy-saving measures, hoping to solve the thermal energy waste and pollution problems of the boiler. [0003] In Chinese patent 01244858.3, an energy storage type heat pump hot water boiler hot water supply device is disclosed. The water outlet is connected with the water inlet of the electric hot water boiler, the water out...

AI Technical Summary

Problems solved by technology

Its disadvantage is that the water-heated evaporator of the heat pump needs to be connected with the hot water pool, so there are some restrictions on the site

The disadvantage is that if the pipe length is not enough, it will be difficult to recover heat well; and if the pipe length is lengthened, the cost will increase and the structure will be complicated, so it is difficult to balance the two

Its disadvantage is that the high-efficiency heat exchanger uses pin-fin heat exchange tubes, and its heat exchange time needs to be further improved.

Its disadvantage is that the heat exchanger used is a traditional rotary tube, and its heat transfer efficiency and heat transfer speed need to be further improved

Its shortcoming is that the radiator used is a traditional radiator, and its heat exchange efficiency and heat exchange speed need to be further improved
