Problems solved by technology

However, most of the existing hot blast stoves on the market have the following problems: 1. Straight-through furnace, fewer flue gas return trips, short heat exchange time, high exhaust gas temperature, and poor heat transfer effect, which directly affect the overall thermal efficiency of the hot blast stove; 2. An integral partition is added to the heat exchanger area to make the flue gas go through the S-shaped loop. Although the heat exchange effect is enhanced, there are a large number of dead spots for blowing, forming a local high temperature area, which seriously affects the service life of the hot blast stove.

Abstract

The invention relates to a biomass hot blast stove which comprises a body, a heat exchanger and a wind shield. An air inlet and an air outlet are arranged on the body, and the heat exchanger and the wind shield are arranged in the body and located between the air inlet and the air outlet; and the heat exchanger comprises smoke pipes, the wind shield is arranged between the smoke pipes, airflow flowing into the body from the air inlet flows through the smoke pipes in a preset route, the wind shield comprises a plurality of strip-shaped wind shield strips, the two sides of each wind shield stripare provided with a plurality of ventilation openings, and each wind shield strip is arranged between two adjacent smoke pipes.

Description

technical field [0001] The invention relates to the technical field of hot blast stoves, in particular to a high-efficiency biomass hot blast stove. Background technique [0002] Hot air stoves are widely used in industrial and agricultural production, such as electroplating drying, paint baking, food drying, etc. However, most of the existing hot blast stoves on the market have the following problems: 1. Straight-through furnace, fewer flue gas return trips, short heat exchange time, high exhaust gas temperature, and poor heat transfer effect, which directly affect the overall thermal efficiency of the hot blast stove; 2. An integral partition is added to the heat exchanger area to make the flue gas go through the S-shaped circuit. Although the heat exchange effect is enhanced, there are a large number of dead spots for blowing, forming a local high temperature area, which seriously affects the service life of the hot blast stove.
