Environment-friendly natural gas boiler with smoke backflow supplementary heating function

Abstract

The invention discloses an environment-friendly natural gas boiler with a smoke backflow supplementary heating function. The boiler comprises a natural gas boiler body, a cleaning mechanism, a dragging plate and a cleaning ring, a combustion mechanism is arranged at the bottom of the natural gas boiler body, a heating water tank is installed at the top of the combustion mechanism, and the left side of the combustion mechanism is connected with the cleaning mechanism through a smoke exhaust pipeline. According to the environment-friendly natural gas boiler, the cleaning mechanism is installed at the top of the natural gas boiler body, smoke exhausted from a smoke exhaust port can be conveniently filtered, a cleaning plate is arranged in the cleaning mechanism, cleaning work on the surface of a second filter screen is facilitated, blockage of the second filter screen is avoided, the filtering effect is improved, then the filtered smoke is conveyed into the combustion mechanism through a heat preservation pipeline so that the smoke can be heated, and the smoke can be reused.

Description

Technical field [0001] The present invention relates to the technical field of natural gas boiler, in particular, an environmentally friendly natural gas boiler supplemented by flue gas reflux. Background technique [0002] Natural gas boilers include gas boilers, gas hot water boilers, gas steam boilers, etc., of which gas hot water boilers are also known as gas heating boilers and gas bath boilers, and gas boilers are refunded by fuel for gas-free boilers, gas boilers and fuel boilers. The electric boiler is more economical, so most people have chosen the gas boiler as steam, heating, bathing boiler equipment, with natural gas boiler technology, although the shape of the gas boiler varies a variety of variations, but the basic principle There will be no changes, but the natural gas boilers in the current market still have the following issues: [0003] 1. In the process of using the natural gas boiler, there will be more flue gas, and there will be more heat in the flue gas, so...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide an environment-friendly natural gas boiler with flue gas reflux supplementary heating to solve the environmental protection type natural gas boiler with flue gas reflux supplementary heating on the market proposed by the above-mentioned background technology. During the use of the natural gas boiler, it will discharge More flue gas, the flue gas will contain more heat, so that it cannot be reused after the flue gas is discharged, resulting in waste of resources, and there will be more harmful gases and solid particles in the flue gas If it is not filtered, it will cause pollution to the surrounding environment. At the same time, after a long period of use of the natural gas boiler, the inner wall of the water tank needs to be cleaned. Generally, the boiler will stop working during cleaning, and then the inner wall will be cleaned. In this way, the work efficiency is reduced, and at the same time, the water inside the boiler needs to be removed after cleaning. Because there is a large amount of water inside the boiler, water resources are wasted during sewage discharge, which increases the cleaning cost.
