Energy-saving environment-friendly heating furnace generating steam through branched pipe flow dividing

Abstract

The invention discloses an energy-saving environment-friendly heating furnace generating steam through branched pipe flow dividing. The energy-saving environment-friendly heating furnace comprises a first cavity and a second cavity; the second cavity is internally provided with an upper collecting pipe, the lower end of the upper collecting pipe is provided with two rows of branched pipes, a stirring rotation shaft is vertically inserted between the two rows of branched pipes and provided with impellers distributed in an array form; the lower ends of the branched pipes communicate with a lowercollecting pipe; the right side of the lower collecting pipe communicates with a valve pipe through a first fixed connection pipe, the valve pipe is provided with a control valve, and the upper end of the valve pipe is connected with a spiral pipe; and an interlayer is arranged between the first cavity and the second cavity, and the left side of the lower end of the interlayer is provided with asteam guide trough. According to the energy-saving environment-friendly heating furnace generating the steam through branched pipe flow dividing, the contact area between a fire source and fuel gas isincreased through branched pipe flow dividing combustion, thus, combustion is more sufficient, the contact area between a heat source and water is large, the heat dissipation area is large, and the heat transmission efficiency is high; and the water heating speed is increased through wheel stirring, the evaporation efficiency is improved, and waste heat of exhaust gas after combustion can be recycled.

Description

technical field [0001] The invention relates to an energy-saving and environment-friendly heating furnace, in particular to an energy-saving and environment-friendly heating furnace which generates steam by splitting pipes and streams. Background technique [0002] Coal-fired heating furnaces are heating boilers that use coal as the main fuel. They have the following defects: 1) Not environmentally friendly, insufficient combustion, black smoke from the furnace, and a large amount of tar generated, resulting in large emissions of exhaust gas during combustion, which affects the environment. Serious pollution; 2) It is unsafe, the added fuel and coal ash will block the oxygen supply channel, so that the fuel is not fully burned and easily produces carbon monoxide, causing gas poisoning; 3) The heating furnace is mainly operated manually, and it needs to be added in time when using Coal fuel is used to prevent the fire from going out; 4) The heating furnace takes a long time t...

[0002] Coal-fired heating furnaces are heating boilers that use coal as the main fuel. They have the following defects: 1) Not environmentally friendly, insufficient combustion, black smoke from the furnace, and a large amount of tar generated, resulting in large emissions of exhaust gas during combustion, which affects the environment. Serious pollution; 2) It is unsafe, the added fuel and coal ash will block the oxygen supply channel, so that the fuel is not fully burned and easily produces carbon monoxide, causing gas poisoning; 3) The heating furnace is mainly operated manually, and it needs to be added in time when using Coal fuel is used to prevent the fire from going out; 4) The heating furnace takes a long time to ignite, and the heating water temperature rises slowly; 5) The inner tank of the boiler is mostly connected by several steel pipes as the heat absorbing element, the heat absorbing area is small, and the thermal efficiency is only 35-50 %

In addition, there are some small steam generating equipment, the heat-absorbing elements of the liner are thin, easy to break under the high temperature of the flame and the erosion of water, and the service life is short. With the continuation of time, the scale becomes thicker and thicker, and cannot be cleaned, resulting in a gradual decrease in heat absorption efficiency until it is scrapped.

[0003] At present, the steam heating furnaces on the market have small contact area between fire source and gas, insufficient combustion, high heat transfer efficiency, and waste gas with waste heat after combustion is not used
