Abstract
The utility model belongs to the field of garbage disposal equipment and discloses an incinerator with a fixed grate. The incinerator with the fixed grate comprises an incinerator body which is made of refractory material and a water-cooled grate. The water-cooled grate traverses the middle lower part of the incinerator body, a water outlet is higher than a water inlet, and the angle of the plane of the grate and the horizontal plane is from 3DEG to 5DEG. High-pressure air replenishing pipes are uniformly and densely arranged on the incinerator body wall and at the bottom of the incinerator, high-pressure air is filled in the high-pressure air replenishing pipes, and the flow rate of the high-pressure air is 30-100m/s. The incinerator with the fixed grate is reconstructed on the basis of the structure of the existing water-cooled jacket type grate furnace and the existing refractory material type grate furnace, combines the advantage that the refractory material furnace that garbage is thoroughly incinerated as the temperature of the furnace box is high and the advantage that the service life of the water-cooled grate is long, overcomes the defect of the traditional water-cooled jacket type grate furnace that the garbage cannot be thoroughly incinerated as the temperature of the furnace box is low, the cast iron refractory grate is easily oxidized and burnt out at high temperatures, and the service life is short.
Description
Technical field
The utility model belongs to the refuse treatment plant field, relates to the fixed grate incinerator.
Background technology
Burn solid waste such as medical waste, aviation rubbish, house refuse, spoil, wood chip, waste paper and generally adopt the fixed grate incinerator, following two kinds of structures are generally arranged: a kind of is water-cooling jacket formula structure, and a kind of is structure of refractory.Water-cooling jacket formula structure adopts water-cooled grate, though can guarantee the service life of fire grate, because the characteristic of solid waste adopts the grate furnace furnace temperature of water-cooling jacket formula generally to have only 500～600 ℃, solid waste burning is not thorough.Though adopt structure of refractory can guarantee to enter dual firing chamber's flue-gas temperature, reduce the Fuel Consumption of dual firing chamber, and fire box temperature can reach more than 800 ℃, solid waste burning is more thorough, but because incineration temperature is higher, discharge a large amount of corrosive substances in the waste incineration process, adopt casting furnace grate, the easy high-temperature oxydation of fire grate or burn out.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of fixed grate incinerator is provided.
The purpose of this utility model can be achieved through the following technical solutions:
The fixed grate incinerator comprises body of heater and the water-cooled grate made by refractory material, and described water-cooled grate passes across the body of heater middle and lower part, and its delivery port is higher than water inlet, and the angle of fire grate plane and horizontal plane is 3 °～5 °.
Described water-cooled grate caliber is 50～108mm, and the outer wall spacing of adjacent furnace grate tube is 60～120mm.
Described furnace body wall and furnace bottom evenly gather the high pressure secondary air channel are set.
Described upper of furnace body is provided with dog-house, and bottom of furnace body one side is provided with mends the wind interface, mends wind interface one end and is connected with blast apparatus, and an end communicates with described secondary air channel.
The body of heater bottom is provided with the twice ashpit, lays respectively at the both sides up and down of fire grate.
Beneficial effect:
The utility model is recombinated the structure of existing water-cooling jacket formula and refractory material formula grate furnace, body of heater adopts refractory material, and fire grate adopts water-cooled grate, with refractory material burner hearth of the furnace body temperature height, waste incineration advantage completely combines with the advantage of water-cooled fire grate long service life, and it is on the low side to have overcome traditional water-cooling jacket formula grate furnace temperature, the halfway defective of waste incineration, avoid the easy oxidation of employing casting furnace grate stove high temperature again and burnt out the deficiency that service life is short.
The utility model furnace body wall and furnace bottom evenly gather the high pressure secondary air channel are set, and mend wind around discarded object and bottom the fire grate, make oxygenating more even more abundant, and pressure-air enters after preheating in the stove, fuel saving.Pressure-air speed 30～100m/s, burning velocity speeds 5～10 times than generally, makes discarded object have enough air to reach complete combustion effect.
The utility model fixed grate incinerator relatively is fit to burn medical waste, aviation rubbish, house refuse, spoil, wood chip, waste paper etc., also is fit to burn general industry discarded objects such as rubber, the chemical industry dregs of fat.
