Combined type civil energy-saving environment-friendly boiler

Abstract

The invention relates to the technical field of a civil boiler, in particular to a combined type civil energy-saving environment-friendly boiler. The boiler comprises a bottom burning section, a smoke mixing section which is connected with the top of the burning section and a smoke purifying section which is connected with the upper part of the smoke mixing section. The burning section comprises an outer cylinder having an interlaid layer, an inner cylinder having an interlaid layer and having a square wave shape on the cross section thereof, a water inlet tube of the inner cylinder, a water outlet tube of the inner cylinder, a return tube, a boiler water outlet tube, a smoke outlet arranged on the periphery of the inner cylinder, a dust outlet on the bottom of the inner cylinder and a dust baffle. The smoke purifying section comprises a water tank, a boil water inlet tube, a smoke discharging tube, a purifying groove, a purifying groove cover, a smoke discharging tube, and an air inlet tube. The smoke mixing section comprises a bent tube, two semicircular baffles around the outside of the water tank and the bent tube, and a bolt used for connecting the two baffles. The combined type civil energy-saving environment-friendly boiler of the invention has the advantages of reasonable structure, small volume, convenient assembly and maintenance, and is free from dust discharge, energy-saving, environment-friendly and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of civil boilers, in particular to a combined civil energy-saving and environment-friendly boiler. Background technique [0002] my country is one of the countries with the most common use of raw coal direct combustion and the largest coal consumption. At present, the vast majority of industrial and civil boilers in my country can only use raw coal to be fired directly, causing serious dust pollution and energy waste. Chinese patent has announced a patent No. 02287868.8 " smokeless and dust-free environmental protection boiler ", although this boiler has reduced the discharge of flue gas, its structure is complicated, and volume is big, and cost is high, is not suitable for civil use.

At present, the vast majority of industrial and civil boilers in my country can only use raw coal to be fired directly, causing serious dust pollution and energy waste

A Chinese patent has announced a "smoke-free and dust-free environmental protection boiler" with the patent number 02287868.8. Although the boiler reduces the emission of flue gas, its structure is complicated, the volume is large, and the cost is high, so it is not suitable for civilian use.

Another patent number is 200720116909.9 "Three return water civil boiler" also adopts the way of direct combustion of raw coal, and its water circulation mode is hot water from the top and cold water from the bottom. Although it can be disassembled and repaired separately, the effect of dust removal is not good. ideal
