Abstract

A rotary kiln type medical refuse incinerator belongs to waste treatment, and the main technical characteristics are that a feeding port, a bag tearing machine and a measurement flashboard which are arranged from top to bottom are communicated one another, wherein a pipeline of the measurement flashboard is connected with the rotary kiln which is connected with a secondary combustion chamber connected with the upper of a semi-dry absorption tower, the lowers of the secondary combustion chamber and the semi-dry absorption tower are respectively communicated with a slag bin through pipelines, and the side lower of the semi-dry absorption tower is connected with a dust collector through pipelines, the lower part of the dust collector is communicated with the slag bin, the dust collector is connected with a chimney through a pipeline, so that the medical refuse can be independently incinerated and treated without mixing with other refuses, thereby reducing the cross infection source. The treatment cost of medical refuse is reduced.

Description

Rotary kiln type hospital refuse incinerator

(1) technical field

The utility model belongs to waste disposal.

(2) background technology

Hospital refuse is to have pathogen, infects the specific refuse of pathogeny refuse, is different from common rubbish when handling, even buriedly also can relate to polluted source and environment.The incinerator structure of handling at present common rubbish is complicated, and the cost height also is not specially adapted for handling the incinerator of hospital refuse.

(3) summary of the invention

The purpose of this utility model provides a kind of rotary kiln type hospital refuse incinerator, and is simple in structure, with low cost.

The utility model is to realize like this, from top to bottom the charging aperture 1 of Pai Lieing, tear bag machine 2, the metering flashboard 3 be interconnected, the pipeline of metering flashboard 3 takes back rotary kiln 4, the outlet of rotary kiln 4 connects the secondary combustion chamber 5 of setting, the outlet of secondary combustion chamber top connects the top on half-dried absorption tower 6 by pipeline, the below on secondary combustion chamber 5 and half-dried absorption tower 6 is respectively by the logical slag storehouse 8 of pipeline, side-lower on half-dried absorption tower connects deduster 7 by pipeline, the following square tube slag storehouse 8 of deduster 7, deduster 7 connects chimney 9 by pipeline.Axle 10 is fixed on the sidewall that tears bag machine 2 by bearing block, is fixed with multi-disc tooth shape section 11 on the axle 10 side by side, and a conveying worm is respectively established in half-dried absorption tower 6 and deduster 7 belows.

Compare with existing incinerator, the beneficial effects of the utility model are can be with the independent burning disposal of hospital refuse, needn't with other rubbish mixed processing, reduced the cross infection source.Because of hospital refuse does not have special large volume or heavy metal spare, so in input system large-scale pulverizer needn't be set, sorter etc. have been simplified treatment facility, have reduced the processing cost of hospital refuse.

(4) description of drawings

Fig. 1 is a structural representation of the present utility model.

(5) specific embodiment

Hospital refuse falls into bag machine that tears from trash repository, plastic garbage bag is torn rubbish is scattered.Tear on the sidewall of bag machine 2 by bearing block fixed axis 10, on axle 10, vertically be fixed with multi-disc tooth shape section 11 side by side.Rubbish falls into metering flashboard 3 from tearing a bag machine.When the last opening-closing plate of metering flashboard 3 was opened, rubbish dropped on the lower baffle plate, claims to link together with electronic weighing on the lower baffle plate, when reaching predetermined weight, overhead gage is closed automatically, and lower baffle plate is regularly opened by running part control, and rubbish enters rotary kiln 4 at regular time and quantity.Rotary kiln 4 oxygen debt pyrolysis are sealing device.Rubbish enters the technology of secondary combustion chamber 5 through the peroxide oxidizing fire from the outlet of rotary kiln, can rationally control incineration temperature, turbulivity, gas residence time and excess air ratio, guarantees that oxious component thoroughly destroys by fire in the rubbish.

Rotary kiln 4 is a slightly inclined and the steel hollow cylinder of inner lining refractory block, and hospital refuse enters from front end and burns the kiln, rotates with constant speed and reaches the purpose that stirs refuse.Must keep suitable gradient during rotation, glide in order to solid waste.

Rotary kiln preparation has burner, and during start, burner just begins charging after furnace temperature being elevated to the temperature of requirement, and the fuel that uses is fuel oil.Secondary combustion chamber 5 also is equipped with burner.Slag after the burning is expelled to slag storehouse 8 by the cinder notch that removes of secondary combustion chamber 5 bottoms.

Do under absorption tower and the sack cleaner and respectively establish a conveying worm, will deliver to the slag storehouse in the lump except that following flying dust is collected to anti-half tropical formula conveyer.

Half-dried absorption tower utilizes high-efficiency atomizer that calcium hydroxide mud is sprayed in the half-dried absorption tower, and the flue gas that secondary combustion chamber is discharged produces neutralization with the mud that sprays into.Because atomizing effect is good, gas, liquid contact-making surface are big, not only can effectively reduce in the temperature of gas and the acid gas in the gas, and moisture can evaporation fully in spray drying tower in the calcium hydroxide mud that sprays into, and does not produce waste water.A reacted solid product part drops in the ash bucket, and a part enters sack cleaner with flue gas, and moisture for reducing the content of steam in the flue gas, is provided with demister then with smoke evaporative between half-dried absorption tower and sack cleaner.
