Problems solved by technology

[0002] At present, most of the existing medical waste incinerators use rotary kiln or pyrolysis incinerators. Although rotary kiln incinerators are flexible and can operate continuously, their sealing is difficult to handle, and it is easy to make smoke and toxic substances Leakage of harmful microorganisms such as viruses and viruses will cause secondary pollution; pyrolytic incinerators are mostly composed of two split furnaces, which are complex in structure, expensive in cost, and consume a lot of energy
In addition, the above-mentioned treatment devices all perform high-temperature incineration treatment of waste, and cannot recycle the pyrolysis products, so they cannot produce economic benefits

Embodiment 1

[0018] Such as figure 1 A treatment device for medical waste shown includes a pyrolysis furnace 2. The pyrolysis furnace 2 includes a furnace 4 and a closed reaction chamber arranged in the furnace 4. The furnace 4 is provided with a main burner 7 and a compensation burner 6. The compensation burner 6 is connected with an external fuel supply end; the airtight reaction chamber is arranged horizontally, the feed end of the airtight reaction chamber is connected with a hydraulic feeder 1, the discharge end is connected with a slag discharger 3, the feed end and the discharge end Both are equipped with electric valves 5; the closed reaction chamber is provided with an exhaust gas collection port, which is connected with a sub-steam drum 10 and a condensing mechanism in turn, and finally connected to the main burner 7, and the condensing mechanism is connected with an oil storage tank 12.

[0019] The furnace 4 is connected with a flue gas purification system; the flue gas purifi...

Embodiment 2

[0024] A treatment method for medical waste is to use the treatment device for medical waste in Embodiment 1, and includes the following steps:

[0025] 1) The medical waste is pushed into the closed reaction chamber of the pyrolysis furnace 2 by the hydraulic feeder 1, and the furnace 4 of the pyrolysis furnace heats the closed reaction chamber at the same time, so that the medical waste is decomposed in the closed reaction chamber; The feeding speed of the feeder 1 is adjusted according to the heating temperature;

[0026] 2) The pyrolysis gas generated by decomposition enters the condensation mechanism through the tail gas collection port, the condensate is collected to the oil storage tank 12, and the non-condensable tail gas enters the main burner 7 for combustion;

[0027] 3) The decomposed solid residue is discharged from the discharge end through the slag discharge machine 3 and then collected and processed.

[0028] The heating temperature in step 1) is 200-400°C.

Abstract

The invention relates to a medical waste processing device and method. The processing device comprises a pyrolyzing furnace, the pyrolyzing furnace comprises a furnace hearth and a closed reaction chamber arranged in the furnace hearth, the furnace hearth is provided with a main burner and a compensation burner, and the compensation burner is connected with an external connection fuel supply end;the closed reaction chamber is transversely arranged, the feeding end of the closed reaction chamber is connected with a hydraulic feeding machine, the discharging end is connected with a slag discharging machine, and the feeding end and the discharging end are each provided with an electric valve; and the closed reaction chamber is provided with a tail gas collecting opening, the tail gas collecting opening is sequentially connected with a sub steam pocket and a condensation mechanism and is finally connected to the main burner, and the condensation mechanism is connected with an oil storingtank. By means of the medical waste processing device and method, pyrolyzing reaction can be carried out in the full-closed state, leakage is avoided, continuous feeding and discharging are achieved,low-temperature pyrolyzing is adopted, a pyrolyzing product can be subject condensation recovering, and large benefits can be generated.
