Description

Pit furnace chassis convenient to installation

Technical Field

The utility model relates to a pit furnace chassis technical field specifically is a pit furnace chassis convenient to installation.

Background

The application and development of the garbage incineration technology in foreign countries have been in history for decades, and the more mature furnace types include a pulse-type grate incinerator, a mechanical grate incinerator, a fluidized bed incinerator, a rotary incinerator and a CAO incinerator.

Mechanical grate incinerator

The working principle is as follows: garbage enters an inclined downward grate (the grate is divided into a drying area, a combustion area and a burnout area) through a feed hopper, and is pushed downwards due to the staggered movement among the grates, so that the garbage sequentially passes through various areas on the grate (the garbage enters another area from one area and plays a role of turning over the garbage greatly) until the garbage is burnt out and discharged out of a hearth. Combustion air enters from the lower part of the fire grate and is mixed with the garbage; the high-temperature flue gas passes through the heating surface of the boiler to generate hot steam, meanwhile, the flue gas is also cooled, and finally, the flue gas is discharged after being treated by the flue gas treatment device.

The method is characterized in that: the requirements on the material and the processing precision of the fire grate are high, the contact surface between the fire grate and the fire grate is quite smooth, and the gaps between rows are quite small. In addition, the mechanical structure is complex, the damage rate is high, and the maintenance amount is large. The grate furnace has high manufacturing cost and maintenance cost, so that the popularization and the application in China are difficult and serious.

Fluidized bed incinerator

The working principle is as follows: the furnace body is composed of a porous distribution plate, a large amount of quartz sand is added into a hearth, the quartz sand is heated to a temperature of over 600 ℃, hot air with a temperature of over 200 ℃ is blown into the bottom of the furnace, so that the hot sand is boiled, and then garbage is put into the furnace. The garbage and the hot sand are boiled together, and the garbage is quickly dried, ignited and combusted. The proportion of the garbage which is not burnt out is light, the garbage continues to be boiled and burnt, the proportion of the garbage which is burnt out is large, the garbage falls to the bottom of the furnace, after water cooling, coarse slag and fine slag are sent out of the factory by a sorting device, and a small amount of medium slag and quartz sand are sent back to the furnace for continuous use by a lifting device.

The method is characterized in that: the fluidized bed has the advantages of sufficient combustion, better combustion control in the furnace, large dust amount in flue gas, complex operation, higher running cost, higher requirement on the uniformity of fuel granularity, need of a high-power crushing device, serious abrasion of quartz sand to equipment and large equipment maintenance amount.

Rotary incinerator

The working principle is as follows: the rotary incinerator is arranged along the furnace body by cooling water pipes or refractory materials, and the furnace body is horizontally arranged and slightly inclined. The garbage in the furnace body is fully combusted by the continuous operation of the furnace body, and simultaneously moves towards the inclined direction of the furnace body until the garbage is completely combusted and discharged out of the furnace body.

The method is characterized in that: high utilization rate of equipment, low carbon content in ash, low excess air amount and low discharge of harmful gas. But the burning is not easy to control, and the burning is difficult when the heat value of the garbage is low.

CAO incinerator

The working principle is as follows: the garbage is transported to a storage pit and enters a biochemical treatment tank for dehydration under the action of microorganisms, so that natural organic matters (kitchen residues, leaves, grass and the like) are decomposed into powder, and other solids including synthetic organic matters such as plastic rubber and inorganic matters in the garbage cannot be decomposed and pulverized. After screening, the waste which is not pulverized enters the incinerator and firstly enters a first combustion chamber (the temperature is 600 ℃), the generated combustible gas enters a second combustion chamber, and the non-combustible and non-pyrolyzed components are discharged in the first combustion chamber in the form of ash slag. The temperature of the second chamber is controlled at 860 ℃ for combustion, and the high-temperature flue gas heats the boiler to generate steam. The flue gas is discharged to the atmosphere through a chimney after being treated, and the metal glass cannot be oxidized or melted in the first combustion chamber and can be separated and recovered in ash residues.

The method is characterized in that: useful substances in the garbage can be recovered; but the single incinerator has small treatment capacity and long treatment time, the daily treatment capacity of the single incinerator at present reaches 150 tons at most, and because the retention time of the flue gas at the temperature of over 850 ℃ is difficult to exceed 1 second, the content of dioxin in the flue gas is high, and the environmental protection is difficult to reach the standard.

Pulse throwing type grate incinerator

The working principle is as follows: the garbage is sent into a drying bed of the incinerator for drying through the automatic feeding unit, then sent into a first-stage grate, subjected to high-temperature volatilization and cracking on the grate, thrown under the pushing of the pulse air power device, and thrown into a next-stage grate step by step, and at the moment, high molecular substances are cracked and other substances are combusted. And then the slag enters the ash pit and is discharged by the automatic slag removing device after being burnt out. The combustion-supporting air is sprayed from the air holes on the grate and mixed with the garbage for combustion, and the garbage is suspended in the air at the same time. The volatilized and cracked substances enter the second-stage combustion chamber for further cracking and combustion, and the unburned flue gas enters the third-stage combustion chamber for complete combustion; the high-temperature flue gas heats steam through the heating surface of the boiler, and meanwhile, the flue gas is cooled and then discharged.

The bottom of burning furnace all has a stove chassis that is used for the thing to burn in each, and present stove chassis all adopts holistic project organization, changes the maintenance in-process at the stove bottom in later stage and need assist with the help of large-scale device to dismantle the change, leads to the later maintenance degree of difficulty big like this.
