Problems solved by technology

Because we can do little to reduce the volume of waste generated every day, the transportation of waste has become the most troublesome and expensive problem for government agencies in various countries.
Although personal computers have successfully entered every family and company line, we still cannot find any relevant waste disposal devices on the market, which are suitable for installation in homes or factories to deal with our own garbage, industrial waste, etc. waste and other waste

Embodiment Construction

[0035] see figure 1 , The present invention provides a smokeless waste disposal method that does not involve incineration and can reduce the volume and weight of the waste into a powdery and sterile substance that can be used as a plant fertilizer. Waste disposal method of the present invention has included following steps:

[0036] Step A: Put a predetermined amount of waste in the cooling chamber and then seal it. This cooling chamber should be insulated. The larger the volume of waste, the larger the cooling chamber.

[0037] Step B: Surround the waste with a predetermined amount of liquid nitrogen in the cooling chamber for a predetermined time, rapidly cooling the waste to below -128.9°C.

[0038] Liquid nitrogen is commonly used in the frozen food industry because liquid nitrogen can quickly freeze any substance to very low temperatures. Spray liquid nitrogen around the waste in a closed cooling chamber until all waste is exposed to liquid nitrogen both on the outsid...

Abstract

The present invention provides a waste treatment process and device thereof which can reduce the size and weight of organic waste by decomposing the waste to powder form and bacteria free substance that may be used as a kind of fertilizer for plants. The waste is first frozen by liquefied nitrogen in a cooling chamber to a temperature less than -200 DEG F., wherein during this freezing procedure, the gas generated from the waste must be removed from the cooling chamber. Then, the frozen nitrogen is immediately transferred to a heated chamber having a temperature of at least 160 DEG F. but not exceed 200 DEG F. During this heating procedure, the water content of the waste is sucked out of the heated chamber, so that the waste is decomposed to form the bacteria free powder.

Description

technical field [0001] The present invention relates to waste treatment, in particular to a treatment method and a treatment device for waste. Background technique [0002] Humans have created civilization, but they have also created garbage. Thousands of tons of waste are produced every day, in every place, from households to industrial sites. Therefore, waste disposal has become a headache that governments of all countries must solve urgently. [0003] Bacteria and toxic waste gas produced by organic waste have endangered human health. And plastic waste made of polyvinyl chloride, foam rubber and other similar substances can take hundreds of years to decompose. [0004] Generally speaking, burial, incineration and recycling are the most common methods of waste disposal, however, burial occupies a large amount of land; incineration produces air pollution; and recycling requires the efforts and cooperation of many people, and the related economic benefits are not high. ...
