Problems solved by technology

Existing biomass hot water boilers generally have a complex structure, most of the heat energy is transferred to the water in the furnace body to heat it up, but a considerable part of the heat energy exchanges heat with the surrounding environment through the boiler wall, resulting in waste of heat energy, and ultimately leads to the heat exchange of the boiler. Low efficiency and high consumption of biomass fuel

Embodiment Construction

[0014] In order to further understand the content of the invention, features and effects of the present invention, the following examples are given in detail as follows:

[0015] See figure 1 , the biomass hot water boiler equipment for recovering waste heat of the present invention includes a base, a water exchange tank device is arranged on the top of the base, and devices such as burners are mainly installed in the base, and the hot air flow obtained after combustion is heated in the water exchange tank. The device exchanges heat with water to heat it up.

[0016] The base includes a box body 14, the head end of the box body 14 is sealed, and the end is open. In the middle of the inner cavity of the box body 14, a partition 11 with an ash discharge port in the middle is provided, and the inner cavity is divided into a combustion chamber and an ash collection chamber. room. In the middle of the combustion chamber, a plurality of burners 12 are installed through brackets. A...

Abstract

The invention relates to a biomass hot water boiler equipment for recovering waste heat. Including the base and the water exchange tank device; the base includes a box body, and a partition with ash discharge port in the middle is provided in the middle of the inner cavity; multiple burners are installed in the middle of the combustion chamber, and a The cloth auger; the heat exchange tank device includes the gas main pipeline in the middle, the upper end of the gas main pipeline is sealed, the lower end is open and extends into the combustion chamber; the outer cylinder, the middle cylinder and the inner cylinder are also installed on the top of the box ; There is a smoke exhaust duct between the tops of the middle cylinder and the inner cylinder, and a chimney is provided on the top of the smoke exhaust duct; multiple heat exchange components are installed between the gas main pipeline and the inner cylinder ; There is a heat exchange spiral tube in the space between the outer cylinder and the middle cylinder, and the upper and lower ends of the heat exchange spiral tube pass through the side wall of the outer cylinder; a plate heat exchanger is also included. The invention has the advantages of compact structure, high heat exchange efficiency and effective collection and utilization of waste heat.

Description

technical field [0001] The invention belongs to the technical field of biomass boilers, and in particular relates to biomass hot water boiler equipment for recovering waste heat. Background technique [0002] Biomass boiler is a type of boiler, which refers to a boiler that uses biomass energy as fuel, and is divided into biomass steam boiler, biomass hot water boiler, biomass hot air stove, biomass heat conduction oil furnace, vertical biomass boiler , Horizontal biomass boiler, etc. Because biomass is used as fuel, it has the characteristics of energy saving and environmental protection, so it has been more and more widely used in modern life. Structurally, a biomass boiler generally includes a feed assembly, a combustion assembly, an air supply assembly, and a soot blow assembly, etc., which respectively realize the feed, combustion, air supply, and soot blowing of biomass fuel. [0003] Biomass hot water boilers are used to burn biomass fuel and provide hot water for p...
