The invention discloses an operating method of a rotary waste incineration fly ash microwave sintering ceramsite. According to the method, waste incineration fly ash and pyrite cinder are mixed and granulated, the granulated waste incineration fly ash and pyrite cinder and microwave coupling agent powder enter a rotary furnace body together to be subjected to microwave sintering, by obliquely arranging a rotary reaction furnace, the ceramsite is subjected to microwave heating while rolling and mixing are carried out, the ceramsite clinker is separated from the microwave coupling agent when thesintering is carried out, and the separated microwave coupling agent is used as a raw material to be returned and reused; the utilization rate of the microwave coupling agent is improved by the innovation, meanwhile, the preparation process is simple, and the energy is fully utilized; the problem that a large amount of harmful flue gas needs to be purified in an traditional sintering technology is solved, the industrialization process of incineration fly ash microwave sintering is promoted, and the method is particularly suitable for the fly ash harmless treatment which is taken incinerationfly ash ceramsite as a purpose..

The invention provides a multiple intelligent protection heating table and safety control method thereof, and relates to the field of intelligent homes. The multiple intelligent protection heating table comprises a fireproof systemarranged on a table top body and a foot rest and a safety control system. The safety control method comprises the following steps: detecting whether a working state of a heat source of the heating table is in abnormal or whether a flame detection signal for indicating the naked flame existing in the heat source is received; when detecting that the heat source is in the abnormal working state, switching off power supply of the heat source, and setting the heat source in an instruction of a non-working state; when the heat source is in the normal working state, setting the heat source in the non-working state while receiving the flame detection signal, refusing to carry out the heating instruction, and executing a firefighting instruction through the starting of a fire extinguishing system. The heating table provided by the invention is good in heat effectand high in security performance, and can realize automatic extinguishing remediation; and the table is simple in structure, low in cost and suitable for public population.

The invention relates to a microwave heating type cracking furnace for saving fuel resources in a production process. The invention adopts the technical scheme that the microwave heating type cracking furnace comprises a closed heating furnace body and a matched heating, pressure-maintaining and pyrolysis atmosphere maintaining mechanism and adopts a structure integrating pyrolysis, carbonizationand activation. The structure comprises the furnace body and a sliding sealed cover plate which is arranged at the furnace top; the pyrolysis furnace body comprises a pyrolysis furnace chamber which uses a microwave heat source and an activation chamber arranged below the pyrolysis furnace chamber; wherein the pyrolysis furnace chamber is in a positive-pressure, nitrogen-atmosphere and movably sealing-type structure; the sliding sealed cover plate at the top of the pyrolysis furnace chamber is provided with a reverse V-shaped groove rail made of sealing material and a sealing-type friction pair; the reverse V-shaped groove rail is made of embedded sealing material; and the sealing-type friction pair slides with the matched reverse V-shaped groove rail arranged at the upper end of the pyrolysis furnace body. The structure comprises a shell-type stand, and a space in the furnace body is separated into the pyrolysis furnace chamber and the activation chamber by the match of a sealing separator II and the elastic sealing material arranged on a shell in match with a movable sealing matching part. The invention integrally realizes four-in-one operation and has simple structure and strong reliability.

The method relates to a rotary type microwave oven, a system and a method for preparing activated carbon, which solve the problem that the conventional technology source cannot be fully used. The rotary type microwave oven adopts the technical scheme that the rotary type microwave oven is provided with a sealed shell cylinder structure ring and a matched microwave heater, wherein a sealed shell cylinder is a horizontal rotary type sealed shell cylinder; the inner space of a sealed shell is provided with a material distributing chamber, a processing chamber and a cooling chamber which are connected in turn; a front end of the material distributing chamber is provided with a feeding hole; the material distributing chamber and the processing chamber, and the processing chamber and the cooling chamber are in positioned connection respectively; two ends of the processing chamber are connected with the material distributing chamber and the cooling chamber respectively and are arranged on a friction driving wheel and a friction driven wheel; the friction driving wheel is driven by a motor; and the tail end of the cooling chamber is provided with a discharging hole and a smoke outlet. Therotary type microwave oven is used in the system and the method for preparing the activated carbon. The rotary type microwave oven has the advantages of uniform heating of materials due to microwave heating, large heat radiation area, quick temperature rise and capability of realizing cyclic utilization of heat energy and water vapor.
