Description

Electric field constrained combustion device and electric field constrained garbage incineration power generation device

Technical field

The invention relates to the technical field of combustion and power generation, in particular to an electric field constrained combustion device and an electric field constrained waste incineration power generation device.

Background technique

Combustion currently mainly exists in the processes of garbage disposal, power generation, steelmaking, industrial processing, aerospace, transportation, vehicles and ships, and kitchen cooking. The main pollutants of unconstrained combustion are: dust, nitrate, sulfur, mercury, dioxins, VOCs, nuclear dust, oil mist, oil fume, etc. The main environmental hazards caused by unconstrained combustion are: haze, acid rain, ocean desertification , Atmospheric ozone hole, greenhouse effect, El Nino effect, plant genetic changes, human genetic changes. The main personal hazards caused by unconstrained burning are: cardiovascular and cerebrovascular diseases, respiratory diseases, nervous system diseases, genetic system diseases, frequent malignant tumors, and genetic mutations.

Garbage is a waste product that has lost use value and cannot be used. It is an important part of the material cycle, and it is a solid and fluid substance that is not needed or used. Garbage disposal has always been a problem that plagues the world today. The collection, storage, transportation, stacking, disposal, and recycling of garbage will cause harm and impact on the surrounding environment. The faster the society develops, the more trash is produced, and the more trash is troubled. Specifically, microplastics derived from plastic products themselves release toxic and harmful substances, such as heavy metals, persistent organic pollutants (such as flame retardants, polychlorinated biphenyls, ortho-benzene plasticizers, etc.), which can affect the marine ecological environment. At the same time, microplastics will pass through the marine food chain and finally enter the human food chain, thereby posing a threat to human health and safety, and affecting human health and quality of life. In order to alleviate waste pollution, we are currently actively advocating and promoting the classification of household garbage, which is divided into four categories: dry garbage, wet garbage, recyclables and hazardous garbage, some of which have no renewable value, such as long degradation cycles. Plastic products that are difficult to screen, or combustible mixed waste that can only be simply and uniformly treated, can be burned. However, waste incineration can lead to secondary pollution of the environment, including waste gas discharged after incineration, fly ash after combustion, foul odor, etc., especially air pollution caused by the emission of flue gas particles. At present, some countries or regions have successively established centralized waste incineration power stations, but almost all of these power stations are facing the problems of waste transportation, stacking, combustion emissions, etc., and cannot operate. Therefore, it is necessary to study how to solve the problem of waste storage and transportation, discharge secondary pollution, and realize efficient recovery of organic energy, so as to completely change the structure of social energy utilization.

In the currently disclosed technology for controlling combustion by using an electric field, because the combustion flame trembles up and down, the combustion flame is likely to contact the corona electrode of the electric field, resulting in failure of the electric field and the inability to control the combustion.

Summary of the invention

The purpose of the present invention is to provide an electric field constrained combustion device and an electric field constrained waste incineration power generation device. The present invention uses at least two electrodes to form an electric field, where at least one electrode is in contact with the burning flame, and part of the combustion occurs in the electric field. The electric field is used to confine the liquid particles and/or solid particles in the combustion flame to change the shape of the combustion flame. And the combustion mode, so that the particulate matter in the combustion is fully burned, and the volatilization of the particulate matter is reduced. In the present invention, different groups of discharge electrodes are arranged in sequence in the order of the distance to the confinement electrode near the burning flame. When the burning flame shakes to contact with a group of discharge electrodes, the electric field generated by the group of discharge electrodes and the confinement electrode is caused. Failure, compared with the group of discharge electrodes, the electric field generated by the group of discharge electrodes farther from the confinement electrode begins to restrain the burning flame in it, and so on, when the burning flame is in an unstable state of shaking up and down In this case, at least one confinement electric field can still be maintained to confine the burning flame. The present invention uses the electric field formed by the at least two electrodes to constrain the combustion flame generated by garbage incineration, so that the garbage incineration is more fully, and the volatilization of flue gas particles is reduced. After garbage incineration, high temperature and high pressure tail gas is obtained, and the high temperature and high pressure tail gas is used for Power generation and exhaust gas purification treatment, thereby realizing waste energy recycling and reducing environmental pollution.
