An energy-efficient and environmentally friendly hot air boiler is involved in heating boiler equipment. It is composed of the furnace body connecting the waste heat use box of the flue gas. The furnace body includes furnace, grate, furnace, ash box, furnace door and smoke vent at the top of the furnace. The flue gas enters the smoke box through the exhaust pipe, and then enters the chimney through the smoke vent. The cold air is drumbed into the furnace body, heated in the interlayer between the furnace body and the furnace gallbladder, and then heated in the waste heat utilization box of the flue gas, and then discharged by the hot air exhaust vent. A downward opening buckle cover is arranged between the furnace body and the furnace chamber, the bottom edge of the buckle cover is suspended, and the convection gap is formed between the bottom and the lower boiler body seat plate, and the hot air can enter the second heating interlayer through the convection gap through the first heating interlayer. The furnace is provided with a horizontal heated core tube. The waste heat of flue gas is also used as a sandwich structure. The beneficial effects of the invention are: the cold air is heated, the heat exchange path is wide, the heat exchange is sufficient, the heat efficiency is high, the flue gas enters the front smoke box from the furnace chamber, and enters the rear smoke box after the reentrant smoke pipe is discharged, and the energy saving and environmental protection effect is obvious.

一种节能高效环保热风锅炉
:本专利技术涉及供热锅炉,特别涉及为养殖大棚供热风用的热风锅炉。
技术介绍
:目前规模化养殖场养殖大棚的供暖多采用水暖自动调温系统,其包括热水锅炉、散热器、调温风扇、微电脑控制器等,调温效果好,但,设备造价较贵,一些小型养殖场往往承受不起,所以目前诸多小型养殖场多愿采用简易热风锅炉供暖设备,例如火管式、导热翅片式等热风锅炉,但目前的大多数热风锅炉构造简单,冷风进入锅炉内受热回程短、热交换不充分、烟道设计不合理余热利用不好等,致使热效率低耗能高,燃烧不彻底产生冒黑烟粉尘等污染。
技术实现思路
:本专利技术之目的,在于提供一种节能高效环保热风锅炉,它热效率高,节能高效环保,供暖效果好,价格便宜,特别适于小型养殖场供暖使用。本专利技术之
