Hospital waste burn-out furnace and burn-out treatment method

Abstract

The invention provides a hospital waste burn-out furnace and a burn-out treatment method. The hospital waste burn-out furnace comprises a waste burn-out furnace body, a rotary dryer, a rotary carbonization furnace, a waste heat boiler, a basement and an exhaust gas burn-out furnace. The hospital waste burn-out furnace and the burn-out treatment method are characterized in that a forklift charges,waste enters the rotary dryer to be dewatered, a dry waste distributor adds materials into the rotary carbonization furnace for high-temperature carbonization, generated mixed gas is blown by an air blower into a carbonization furnace body to be burnt, thus heat is supplied to the rotary carbonization furnace, high-temperature gas on the upper part of the carbonization furnace body is delivered into the rotary dryer to dewater the waste, gas out of the dryer is delivered into the waste heat boiler for air-distribution burning, a chain fire grate uses fire coal for conducting temperature increasing and heat supplying on the carbonization furnace body and the waste heat boiler, gas at the top of the burn-out furnace body is delivered into the exhaust gas burn-out furnace for air-distributionburning, ignition is conducted through liquefied gas flame, hot water is delivered into the waste heat boiler for supplementing water, exhaust gas enters a water bath dust removal desulfurization tower and then is discharged into air, in the whole production process, waste heat is utilized again and again, and a co-product is pressure steam and can be used by all departments in a hospital.

Description

technical field [0001] The invention discloses a hospital garbage incineration furnace and an incineration treatment method, belonging to the technical field of environmental protection equipment. Background technique [0002] The garbage generated by the hospital is very messy, including household garbage and medical garbage. Medical garbage includes plastics, waste paper, gauze, medicine bottles, post-operative waste, etc. Domestic garbage also includes leftovers, etc. Wet garbage has a high moisture content and is cumbersome to deal with; it needs to be collected and transported manually; if the collected garbage is incinerated, it will cause serious air pollution and produce heavy metals, dioxins, carbon monoxide, carbon dioxide, etc. Such harmful substances and gases seriously endanger human life safety and the ecological environment; deep burial requires land occupation, and will pollute land and water sources, causing harm to future generations; a large hospital will ...
