Continuous microwave cracking device for biomass energy

Abstract

The invention discloses a continuous microwave cracking device for biomass energy. The device comprises a cracking furnace, a microwave generator, a vibrating screen, more than one condensers, an oil-gas separator, a scrubber tank, a drying tank and a gas storage tank, wherein the cracking furnace is connected with a storage bin; a spiral screw rod is arranged in the cracking furnace; the microwave generator is communicated with the cracking furnace; a feed port of the vibrating screen is communicated with a discharge port of the cracking furnace; a fine material discharge port of the vibrating screen is connected with a slag storage tank through a waste slag conveyer; a coarse material discharge port of the vibrating screen is communicated with the storage bin through a spiral lifter; the condenser and the cracking furnace are communicated through a connecting pipe; the condenser is connected with an oil storage tank; the oil-gas separator is communicated with the oil storage tank; the washing gas tank is communicated with the oil-gas separator; the drying tank is communicated with the scrubber tank; and the gas storage tank is communicated with the drying tank. The device has the advantages of simple structure, easy execution, high operability, and convenience for promotion and application, has no need of adding any fuel, and can really change solid wastes into wealth.

Description

technical field [0001] The invention relates to the field of solid waste treatment equipment, in particular to a continuous microwave cracking biomass energy device. Background technique [0002] With the development of my country's urbanization process and the improvement of population level, more and more urban garbage is produced, and the growth rate has exceeded 5%-8% in recent years. In 2001, municipal solid waste reached 135 million tons. Over the years, cities have accumulated 6.6 billion tons of garbage dumps, occupying more than 3.5 billion square meters of land. More than 200 of the 660 cities in the country have been surrounded by garbage. How to properly dispose of urban waste and realize the harmlessness, reduction and energy conversion of waste has become a major problem faced by countries all over the world. Since the 1970s and 1980s, developed countries such as the United States and Japan have carried out a large amount of research and application of waste...

Problems solved by technology

Since the 1970s and 1980s, developed countries such as the United States and Japan have carried out a large amount of research and application of waste cracking technology, but there are many problems: when using external heat heating method, the carbon accumulation on the wall is serious, and the system is difficult to maintain for a long time. Stable operation; when using the internal heat heating method, the garbage needs to be fully burned to generate enough heat, but it may lead to the generation of dioxins; the problem of thermal hysteresis is serious, the thermal efficiency is low, and the level of resource utilization is reduced; affected by my country's consumption habits and garbage Influenced by the receiving method, the garbage contains a lot of water and various types, resulting in a large amount of energy consumption, and harmful components and heavy metals may enter the air, causing pollution to the environment

[0003] The patent publication number is CN101712458A, which discloses a method of producing hydrogen by high-temperature pyrolysis for half a month. The method is to send normal-temperature garbage containing a certain amount of moisture into a high-temperature environment above 1000°C for cracking and reorganization. During the heating process, the garbage absorbs heat energy to dehydrate and Precipitate volatile components and tar, when the temperature rises above 700°C, the volatile components and tar are cracked into small molecules, and finally generate hydrogen, carbon monoxide, carbon dioxide or ash to obtain hydrogen; this method cannot fully crack the volatile components and tar, Will form aromatic hydrocarbons and other substances, will form highly toxic substances such as dioxin, and pollute the environment
