s4, tail gas treatment: the calcined residue is subjected to dry deacidification, activated carbon adsorption, cloth bag dust removal and flue gas purification, and can be discharged into the air after being detected to be qualified;

s5, cleaning a filter screen: when the bold material on the filter screen 3 piles up to a quantitative time, for not influencing the normal use of filter screen 3, the staff at first starts lifting unit 42 and drives filter screen 3 and remove to feed pipe 2 top, starts rotating assembly 43 and drives filter screen 3 and rotate after that to clear away the bold waste material on the filter screen 3 can.

The implementation principle of the hazardous waste incineration treatment equipment and the process thereof in the embodiment of the application is as follows: when workers need to burn and decompose waste materials, the waste materials are firstly placed into a feeding port of a feeding pipeline 2, then the waste materials fall onto a filter screen 3 along with gravity, the filter screen 3 can intercept large waste materials in the waste materials, then the intercepted waste materials are temporarily stored on the filter screen 3, the waste materials passing through the filter screen 3 firstly fall onto a buffer plate 7, the buffer plate 7 buffers the waste materials and then fall onto a sealing door 5, when the waste materials on the sealing door 5 are accumulated to a certain amount, an opening and closing mechanism 6 controls the sealing door 5 to be automatically opened, then the materials on the sealing door 5 slide into a rotary kiln body 1 from the feeding pipeline 2 to be burned, and meanwhile, after the tail gas generated after waste material calcination is subjected to harmless treatment and qualified detection, the tail gas is discharged into the air; when the large waste materials on the filter screen 3 are accumulated to a certain amount, a worker starts the cleaning mechanism 4, the cleaning mechanism 4 drives the filter screen 3 to ascend to the outer side of the feeding pipeline 2, the large waste materials on the filter screen 3 are cleaned, and then the cleaning mechanism 4 restores the filter screen 3 to the initial working position again; the bold waste material that gets into charge-in pipeline 2 of filter screen 3 carries out the interception and handles, and can clear up the bold material of keeping in on the filter screen 3 automatically through clearance mechanism 4, thereby not only make charge-in pipeline 2 be difficult for blockking, the stability of incineration disposal equipment has been improved, and the staff need not manual clearance, staff's intensity of labour has been alleviateed, the work efficiency is improved, simultaneously charge-in pipeline 2's sealing door 5 need not to rely on the power equipment drive to open or close, the waste of electric power resource has been reduced, environmental protection more.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
