Air stream heat carrier flow process
Cold air M0 first by the many backhauls deflector type UTILIZATION OF VESIDUAL HEAT IN heat exchanger preheating above drying system by filter screen, is preheating to more than 60 ~ 70 DEG C by environment temperature, becomes warm air stream carrier M1; Warm air stream carrier M1 flows through the middle and upper part kuppe be arranged on outside body of heater, and namely between kuppe and body of heater outer surface, the external exterior heat amount of absorption furnace, through secondary temperature elevation, becomes thermal air current carrier M2; Thermal air current carrier M2 flow through above combustion chamber by heating epicoele, by burning produce heat energy directly heated by thin stainless steel hot guide plate, third time heat up become air stream heat carrier M3; Air stream heat carrier M3, in the outer tube flowing through many backhauls deflector type shell heat exchanger and interior ligament, the 4th Long travel heat absorption heats up, and becomes air stream heat carrier M4; When air stream heat carrier M4 is admitted to drying pipeline, temperature is more than 220 DEG C, is finally blown out by oven dry hot-air mouth, dries crops etc.
Air heat source stroke
1. cold air Q0(enters bottom grate; 2. two air outlets that stage casing, combustion chamber is arranged enter; 3. in, high section multiple aperture enters), become air heat source Q1 through combustion furnace combustion heating; Air heat source Q1 flows through the interior pipe in many backhauls deflector type shell heat exchanger, heats air stream heat carrier M3, carries out heat release cooling and becomes air heat source Q2; Air heat source Q2 flows through the interior pipe in many backhauls deflector type UTILIZATION OF VESIDUAL HEAT IN hot flood dragon device, carries out heat trnasfer to M0, and carry out heat release cooling and become air heat source Q3, last exhaust port is discharged.During discharge, the temperature of tail gas is less than 80 DEG C.
Multistage stereo burning formula biological particles combustion furnace
Granular fuel filled it up with by the hopper doing the inverted cone shape of a dress particulate material, pass through feed opening, evenly be transported on the fire grate of igniting chamber according to technological parameter by spiral flood dragon, particulate material is lighted with by ignition system, particulate material section at the bottom of grate, by the air-supply of air blast brute force, makes fuel suspend and is in boiling half gasification, and combustion state.The biological granular fuel of Boiling Combustion by the solid cigarette ash being cracked into the fuel gas such as part carbon monoxide, hydrogen, methane after high-temp combustion and do not burn, up ascension; Two air outlets be provided with in body of heater stage casing, Formation cross-section formula is blown, and is burning oxygen supply again, for Thorough combustion provides sufficient oxygen; Fuel gas and the solid cigarette ash do not burnt, continue high section in up ascension to combustion chamber, and the multiple aperture herein arranged, multi-faceted rotary-cutting type 3d air delivery port system third time forms three-dimensional oxygenating in combustion chamber, realizes Thorough combustion.The heat energy that burning produces is passed to by the air stream heat carrier M2 in heating epicoele by thin stainless steel hot guide plate.By the air stream heat carrier M2 in heating epicoele, be by the gap between the middle and upper part kuppe be arranged on outside body of heater and body of heater outer surface, the external exterior heat amount of absorption furnace is absorbed heat through the air stream heat carrier M1 of secondary temperature elevation and is heated up.By the air stream heat carrier M2 in heating epicoele, become the air stream heat carrier M3 of higher temperatures through heat temperature raising, air stream heat carrier M3 is sent by outside heating epicoele by blast, enters many backhauls deflector type shell heat exchanger.Air stream heat carrier is achieved by automatic control system and heats up at multistage stereo burning formula biological particles combustion furnace.After burning, lime-ash drops in ash bucket, and lime-ash is removed after piling up full ash bucket automatically or by hand.
Many backhauls deflector type shell heat exchanger
Air heat source Q1, at many backhauls deflector type shell heat exchanger by managing in the N group such as first group, second group and upper and lower connected chamber, when flowing, heat being passed to the air stream heat carrier M3 that folding between interior pipe and outer tube flows by inner tubal wall, realizing Long travel transferring heat.In this stage, air heat source Q1 becomes air heat source Q2 after heat transmission, timing or when needing clear dirt according to automatic alarm system prompting, pulls down outer tube and removes obstacles, dismantle the black dirt in pipe in the cleaning of upper and lower connected chamber.
Many backhauls deflector type UTILIZATION OF VESIDUAL HEAT IN heat exchanger
Air heat source Q2, at many backhauls deflector type UTILIZATION OF VESIDUAL HEAT IN heat exchanger by managing in the N group such as first group, second group, heat is passed to when flowing the cold air M0 flowed between interior pipe and preheating cavity by inner tubal wall, cold air M0 is under deflector drainage, flow in folding, realize Long travel heat exchange.Air heat source Q2, from more than 200 DEG C, drops to less than 80 DEG C after this stage heat trnasfer, becomes tail gas and discharges.
Timing or according to automatic alarm system prompting need clear dirt time, pull down preheating cavity and remove obstacles.
Air heat source Q2 ' in multistage stereo burning formula biological particles combustion furnace and many backhauls deflector type shell heat exchanger external space.
Air heat source Q2 ' be cold air Q0 from the filter screen bottom drying system entirety, from lower to upper through too much backhaul deflector type shell heat exchanger appearance, by what formed after heat trnasfer; Many backhauls deflector type UTILIZATION OF VESIDUAL HEAT IN heat exchanger is entered by negative pressure induced wind.
Its effect: 1. reduce many backhauls deflector type shell heat exchanger external skin temperatures, protection drying system internal unit or device, remove potential safety hazard.2. heat energy is made full use of.
