Roller and the second roller, the first roller and the second roller drive opposite direction rotating by driving device, and the gap between the first roller and the second roller is to grind
Feeding-passage is pressed, incinerator includes a combustion room and dual firing chamber, and dual firing chamber is located at the top of a combustion room, and a combustion is indoor to be equipped with staged
Fixed grate, double roller charger are located at the top of a combustion room and roll feeding-passage and the feed inlet phase that is located above a combustion room
It is logical, pusher is further respectively had on the steps at different levels of staged fixed grate.However, the medical refuse burning system of the patent disclosure
System haves the shortcomings that following or deficiency: (1), only simply burning to medical waste, do not disclose the medical treatment after burning
The disposition of rubbish；(2) medical refuse burning easily generates secondary pollution；(3) medical waste is not recycled rationally
The energy cannot achieve energy-saving and environment-friendly effect.
For another example a kind of medical refuse burning technique and its system disclosed in Chinese patent application 200610028655.5 are set
Standby, the high temperature incineration for all kinds of clinical wastes is handled, and process flow is passed through: feeding mechanism, incinerator, waste heat boiler, chilling
Tower, flue gas purification system etc., feeding mechanism using storage rubbish turnover box automatic turning charging, incinerator using rotary kiln,
Fire grate and dual firing chamber's combined type incinerator, waste heat boiler recovery waste heat generate steam, and high-temperature flue gas passes through chilling tower, and through more than half
Qualified discharge after dry desulfurization reactor and bag filter gas cleaning processing.Its system equipment includes feeding mechanism, revolution
Kiln, fire grate and dual firing chamber's incinerator, waste heat boiler, chilling tower, flue gas purification system.However, the medical waste of the patent disclosure
Burning process and its system equipment have the shortcomings that following or deficiency: (1), processing cost it is high, be related to a large amount of chilling tower and cigarette
Gas purification system；(2) UTILIZATION OF VESIDUAL HEAT IN of high-temperature flue gas does not have any refer to.
For another example Biohazard Waste processing equipment and Biohazard Waste disclosed in Chinese patent application 201710247182.6
Processing system, Biohazard Waste processing equipment include shell, loading assemblies, destroyer, transmission assembly, microwave high-temperature ashing furnace and
Biohazard Waste to be processed can be transferred to enclosure interior by controller, loading assemblies, and destroyer is located in inner walls, be passed
Defeated component is located at the lower section of destroyer, flows into transmission device, is then communicated to micro- through the broken Biohazard Waste of destroyer
In wave height temperature ashing furnace, it is transferred in follow-up equipment after the processing of microwave high-temperature ashing furnace.However, the medical treatment of the patent disclosure is useless
Gurry processing equipment and Biohazard Waste processing system have the shortcomings that following or deficiency: (1), processing cost it is high, be related to microwave
