Description
Technical field:
The present invention relates to a kind of hot-blast stove, particularly a kind of hot-blast stove that utilizes biomass energy to burn to realize the cereal drying.
Background technology:
At grain drying, there is certain defective in some similar hot-blast stoves in the market.
Shown in Fig. 1 a and Fig. 1 b, this is a kind of of existing hot-blast stove, its combustion chamber below square structure or top, combustion chamber arc, the hot-air that burning produces enters in the heat-exchange tube, waste gas is discharged from the top, and the hot blast after the exchange imports corresponding crop dryer by airduct.
Shown in Fig. 2 a and Fig. 2 b, this is another kind of existing hot-blast stove, with the difference of Fig. 1 be the heat-exchanger pipeline horizontally-arranged, the hot-air after the burning enters heat exchanger from the corresponding end of fire door.Cold wind through heat-exchange tube, needs crop dryer from entering after the other end is collected from burner hearth one end.
In sum, mainly there is following problem in the structure of these two kinds of hot-blast stoves:
(1) tubing heat exchanger and combustion chamber accumbency, its shortcoming is that heat-exchange tube stops up easily, influences heat exchanger effectiveness, waste fuel, thus also often, heat-exchange tube reduces heat exchange area because of stopping up, cause not reach needed expection hot blast temperature.The combustion chamber accumbency, the combustion chamber is long and narrow, and the combustion chamber height generally is no more than 1000mm, makes the limited combustion chamber active combustion volume-diminished in combustion space originally, can cause the fuel can not active combustion (particularly rice husk, timber, stalk etc.), wastes energy.
(2) combustion chamber does not have combustion-supporting air compensation device, causes the part of fuel incomplete combustion.
(3) the heat exchanger cleaning is not thorough
(4) high-temperature region does not have refractory material or adopts general refractory material, easy deformation, and service life is short.
(5) partial design adopts the mode that directly adds the heat exchange pipe, and the heat-exchange tube of general material directly heats through naked light, and easy deformation, explosion can't avoid naked light directly to enter crop dryer, cause fire.
(6) in the control: function is simple, the alarm free device.
(7) in the conveying of fuel: simple in structure, amount can perfect adaptation, causes actual temperature difference fluctuation excessive, and in the cereal dry run, the hot blast temperature fluctuation is excessive, influences Quality of Grain Drying.
Summary of the invention:
In view of above-mentioned technical problem, the invention provides a kind of hot-blast stove that utilizes biomass energy to burn to realize the cereal drying.This living mass-energy hot-blast stove has replaced existing kerosene and diesel oil on fuel is selected, select the multiple discarded objects that are close to such as waste wood, coal, rice husk, stalk to make fuel, make compared to the cereal drying cost of script (fuel oil) Cirulation type grain dryer and reduce about 60%.In addition, this equipment adopts multiple interlocking control design that stable thermal source is provided, thereby improves Quality of Grain Drying.And combustion chamber and high-temperature hot-air passage adopt special refractory, in the service life of having improved hot-blast stove, guarantee the security that hot-blast stove uses.Certainly, present device also is equipped with cyclone dust collector and air filter screen, thus meet energy-conservation, the social progress requirement of environmental protection.

The operation principle of living mass-energy hot-blast stove of the present invention is: fuel is sent into behind the combustion chamber in the burner hearth internal-combustion by airlock, hot-air imports heat-exchange tube (because fire box temperature is higher by smoke exhaust fan, pouring fireproof material in the elbow), for making full combustion of fuel, provide the burning required air by mending the wind blower fan, tail gas is discharged after via the cyclone dedusting, and cold air enters from two side's preformed holes up and down, absorbs heat that heat-exchange tube distributes after form warm-air supply after the heat exchanger heats.
In addition, the course of work of this living mass-energy hot-blast stove and function: by the fuel in the ignition combustion chamber, will be through burning heated hot air heated delivery heat exchanger, the tail gas of residue discharges after the dedusting of whirlwind dust storage chamber after heat exchanger absorbs, clean hot-air after the heat exchange imports crop dryer by heat-exchange tube provides cereal dry required thermal source, hot-blast stove is self-feeding in the course of the work, and is temperature automatically controlled, and each coupling part running has the security monitoring warning system.
Living mass-energy hot-blast stove of the present invention possesses following characteristics.
1. integral frame:
A. the cold wind mouth enters about the dead astern, and characteristics are fully to collect thermal source, particularly go up the cold wind mouth and can reduce main hot-air channel (combustion chamber upper periphery) temperature, increase the service life, and avoid producing the distortion that Yin Gaowen causes
B. heat exchanger is opened up cleanout up and down, can regularly clean the residual comburant of heat exchanger inside pipe wall fully, promotes heat exchanger effectiveness
C. the wheeled design of lower margin, conveniently moving
D. spacing 90mm between dividing plate and the shell within cold wind trend and the heat exchanger, and do the cold wind import makes whole hot-blast stove outer wall non-scald on hand at work, avoids that operating personnel are unexpected to scald
E. the position of feeding and benefit wind is accurately selected, and guarantees that there is abundant combustion-supporting oxygen in each corner, combustion chamber, does not have the burning dead angle, makes full combustion of fuel
F. the use of special refractory guarantees that the high-temperature region is indeformable, not explosion, longer service life
2. in the control;
Each warning device and export clean hot-air channel smoke detector and guarantee work safety.
The concrete control procedure of living mass-energy hot-blast stove of the present invention is as follows:
1. press start button: (start or hot blast temperature be lower than setting value), the low temperature lamp is bright → and smoke exhaust fan, pressure fan, feeding fan start → Blowing stopper (feeding valve) delayed startup simultaneously
2. Blowing stopper starts back circulation material conveying (for example under the normal condition, after Blowing stopper time-delay 5S starts, stopping 5S behind the feeding 8S, intermittently feeding)
3. hot blast temperature reaches setting value time, and the low temperature lamp extinguishes, and high temperature lamps is bright → and Blowing stopper shuts down and shuts down behind (promptly stopping the feeding) → three typhoon machine time-delay 30S (can set value according to practical adjustments)
4. hot blast temperature is reduced to when setting value following 2 ℃, and machine begins action with reference to step 1
5. run in the machine run fault → alarm sound → each electric device out of service → the bright demonstration of warning lamp place fault
6. 1 running set by step after fault is got rid of.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
