Steam circulation device of microwave heating garbage treatment equipment

Abstract

The invention relates to a water vapor circulation device for a microwave-heated garbage disposer, which comprises a processing tank arranged in a body; a container containing a processing object is arranged in the processing tank; microwaves are used to dry the processing object by using a magnetron and a waveguide; the processing tank The internal water vapor is discharged outward through the circulation fan, and the water vapor forced circulation means circulates the water vapor into the treatment tank for condensation and elimination. The circulation fan forcibly inhales water vapor to form a condensation flow path, which produces a large amount of water vapor and can effectively remove condensation. It is suitable for systems with high output power and shortens the processing time. At the same time, in the process of repeated forced circulation of water vapor, the water vapor is continuously eliminated through condensation and deodorization, so that the pressure inside the treatment tank is lower than that outside, and the leakage of odor can be reduced even if there is a gap. The trace non-condensable gas that has not been condensed in the external condenser contains odor components. After the odor is eliminated by the deodorizer, it flows into the circulation flow path in the system again to continue to eliminate odor and reduce the intensity of odor.

Description

technical field [0001] The invention relates to a microwave heating garbage disposer, in particular to a water vapor circulation device for a microwave heating garbage disposer. Background technique [0002] The hot-air garbage disposal device of the prior art has low heating efficiency and slow processing speed, and odor components are left inside, so after processing, the odor will be discharged when the door is opened. [0003] figure 1 It is a longitudinal sectional view of a prior art garbage disposal device. Such as figure 1 As shown, the structure of the garbage disposal device in the prior art is as follows: the external tank 1 is arranged in the inside of the body, and the internal tank 2 is arranged in the inside of the external tank 1; the inside of the internal tank 2 has a container 4 carrying a garbage disposal object; The inside is provided with a stirrer 3, and the top of the internal tank 2 is provided with a heater 5 for heating garbage; [0004] One si...

Problems solved by technology

[0007] However, the hot-air type garbage disposal device of the above-mentioned prior art has the following disadvantages: the internal pressure of the system is greater than the external pressure by the steam generated inside the internal tank, and when the above-mentioned state is maintained, the smell will flow out to the outside. In order to prevent the above-mentioned phenomenon , the structure of the door needs to be airtight

The above-mentioned problems also occur in microwave garbage disposal devices, so it is difficult to apply to places that require a pleasant atmosphere, such as homes and canteens.

[0009] Use microwave drying to treat garbage and remove the water evaporated from the treatment object. The structure of the industrial waste treatment device is complicated, the operation is troublesome, and there is no device that can completely remove the water and odor generated in the treatment object, so it is not suitable for household waste treatment. device
