Technical Field

The utility model belongs to the straw field of burning, specificly relate to a straw burns coprocessing device.

Background

At present, the main treatment mode of crop straws is incineration, but the incineration of straws scattered by farmers causes serious environmental pollution, generates a large amount of toxic and harmful substances, and threatens the health of people and other organisms. Especially for the crops produced in a centralized manner, the annual straw treatment is a rather troublesome problem. The special burning device for separately constructing the straws has the problems of high cost, short service cycle and resource waste.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems of serious pollution and high cost in the prior art, the utility model provides a straw burning cooperative treatment device.

The technical scheme of the utility model as follows:

the utility model provides a straw burns coprocessing device, its characterized in that includes waste incinerator, waste incinerator is including the dore furnace, rotary kiln and the cold machine of combing that connect gradually, just still communicate through the cubic tuber pipe between kiln hood cover and the dore furnace of the junction of the cold machine of combing and rotary kiln, the cubic tuber pipe with be provided with the straw incinerator before the entrance to the connection of dore furnace, it has the hole to distribute on the straw incinerator oven, leaves the clearance between side and the cubic tuber pipe wall, and the top has the pan feeding mouth.

Preferably, the section of the tertiary air pipe at the straw incinerator is enlarged, and the sectional area of the gap is the same as that of other positions of the tertiary air pipe.

Preferably, the system also comprises an off-line incinerator which is connected with a tertiary air pipe and/or a grate cooler through an air pipe.

Preferably, a straw feeding port is arranged at a smoke chamber between the rotary kiln and the decomposing furnace.

Preferably, the decomposing furnace is provided with a straw feeding port.

Preferably, a straw feeding port or a straw incinerator is arranged at the part and/or the middle section of the tertiary air pipe close to the kiln head cover.

Preferably, an on-line incinerator is arranged above the kiln head cover.

Preferably, a straw feeding port is arranged at the inlet of the grate cooler.

Preferably, a coal injection pipe which is led into the tail end of the rotary kiln is arranged above the grate cooler, and a hollow straw input pipe is sleeved on the periphery of the coal injection pipe.

The utility model discloses beneficial effect as follows:

the utility model discloses utilize ripe waste incineration system to reform transform, help when burning rubbish to handle abandonment straw. Compared with garbage, the straw combustion has high heat value and almost no ash, and is similar to liquid or gaseous fuel, so that the waste heat of the garbage incinerator can be utilized to realize full combustion, and no pressure is brought to subsequent tail gas treatment.

The optimal mode is that the cage-shaped incinerator with holes is arranged at the joint of the tertiary air pipe and the decomposing furnace, the temperature of over thousand hot air in the tertiary air pipe is enough to fully burn the straws, the burning ash and heat directly enter the decomposing furnace along with the wind, and the heat supplement of the decomposing furnace can be realized. When the incinerator is full of straws to be incinerated, hot air can also pass through gaps on two sides, and too large resistance cannot be caused.

In addition, an off-line incinerator can be adopted, or a proper straw feeding port is added in each device. Due to the combustion characteristic of the straws, the burning can be rapidly finished after the straws are added into each feeding port, and the whole equipment cannot be blocked.

The kiln head is short from the ground, convenient to construct, high in smoke temperature and beneficial to combustion, and the defect that the smoke volume can be increased after combustion is overcome, so that the tertiary air pipe needs to be thickened.

The middle section or the rear section of the kiln tail and the tertiary air pipe has the advantages that the flue gas volume is large, the flue gas can directly enter the decomposing furnace, but the height is high, and the construction difficulty and the investment are slightly large.

The utility model discloses can be with the hot flue gas of high temperature who burns rubbish reuse, retrieve a large amount of heats, reduce carbon and discharge, real realization energy saving and emission reduction, and need not to make burning equipment on a large scale, only need on the basis of current equipment carry on a small amount reform transform can, treat to carry out the coprocessing of straw burning when needing, the investment is little, practices thrift and takes up an area of, does not produce extravagantly. The utility model discloses can wholly realize reducing discharging and increase receipts, have very big economic benefits.
