Problems solved by technology

[0009] The purpose of the present invention is to overcome the defect that low calorific value garbage (such as rural garbage) needs to be additionally supplemented with fuel oil or coal in pyrolysis or incineration for power generation, and to provide a low energy consumption (that is, carbohydrate garbage with high moisture content) Decomposition, reduction, and removal of molecular structure water by biochemical degradation), resource utilization (energy in garbage is converted into gas, that is, gas power generation, gas civil or gas industry), reduction, environmental protection, high efficiency and other advantages An energy-saving method of waste dry distillation to gas and gas-fired power generation

Embodiment 1

[0051] as attached figure 1 As shown, the specific steps are:

[0052] i) Pretreatment: Municipal domestic waste is transported by garbage vehicles, weighed by the ground scale and added to the garbage pool. The volume of the garbage pool is about 1000-2000m 3 , a grab crane is installed on the top of the garbage pool for stacking and feeding of garbage; first, the ferrous metal is separated by a magnetic separator, and then manually selected to remove large waste such as masonry, baskets, etc. Another harmless treatment; grab 1000KG of domestic garbage with a grab crane and move it into the bag breaking machine, and the garbage will be broken into bags, and the broken bags will fall into the conveyor and be transported to the drum screening machine for screening 203 kg (water content 9.7%, wt%) of garbage light materials such as waste plastics, paper scraps, cloth, ropes, etc. on the sieve of the sorting machine are collected and utilized, and melon and fruit peels, vegetabl...

Embodiment 2

[0092] as attached figure 1 As shown, the specific steps are:

[0093] i) pretreatment: same as the operation method of embodiment one; Obtain 203 kilograms (water content 9.7%, wt%) of the garbage light material on the sieve, 729 kilograms of garbage heavy material and stone and ironware 68kg under the sieve;

[0094] ii) Biochemical degradation: the same operation method as in Example 1, 729 kg of heavy material under the sieve obtained by pretreatment was subjected to fermentation treatment, and 208 kg of degradation products after fermentation were obtained;

[0095] iii) Retort gasification: adopt the equipment (downdraft gasifier) ​​and operation of "A Pyrolysis Catalytic Gasifier for Domestic Garbage" ZL201320182361.3 authorized by the applicant, and use a reciprocating hydraulic press to convert the above i) 203 kg of light materials collected on the sieve and 208 kg of ii) collected fermentation degradation products are not dried and dehydrated, but are directly tran...

Embodiment 3

[0125] as attached figure 1 As shown, the specific steps are:

[0126] i) Pretreatment: 1000 kilograms of rural garbage (among them, 15 kilograms of waste plastics, accounting for 1.5%, wt%) is transported by garbage vehicles, manually removing large pieces of garbage, masonry and ironware in the garbage, and separating ironware by magnetic separation , and then use the knuckle crusher to shred the garbage into a size below 20 centimeters; the result is: 58 kilograms of stones and metals are separated, and 942 kilograms of other garbage after removing stones and ironware (including waste plastics) 15 kg), collect and reserve;

[0127] ii) Biochemical degradation:

[0128] The method is the same as that in Example 1. The 942 kilograms of garbage collected in the above i) pretreatment are added as fermentation materials into the fermentation equipment for biochemical degradation to carry out the fermentation treatment of biochemical degradation. Through the fermentation treatm...

Abstract

The invention belongs to an energy-saving type garbage dry distillation gas preparation and gas power generation method, in particular to a method for treating garbage to produce gas and generating power through the gas via procedures of pretreatment, biochemical degrading, dry distillation, gasification, gas-liquid separation, gas purification and gas utilization for the garbage. The method has the advantages of energy conservation, environment friendliness, efficiency and continuous treatment of the garbage, and is high in inventiveness, novelty and industrial practicability.

Description

1. Technical field [0001] The invention relates to an energy-saving garbage dry distillation method for producing gas and gas-fired power generation, and belongs to the technical field of environmental protection; 2. Background of the invention [0002] With the development of our country's economy and the improvement of people's living standards, the amount of domestic waste is increasing day by day, especially the amount of organic waste in the vast rural areas is constantly increasing; the organic matter in the waste is easy to deteriorate and rot will affect the environment in which people live; however, Reducing the comprehensive treatment cost of garbage, improving the economic benefits of garbage treatment, making it harmless, reducing and recycling are important key issues for the whole society to promote garbage treatment; [0003] It has been reported in the literature that garbage with a low calorific value (ie, L·H·V) greater than 3344KJ / Kg (or 800 kcal / Kg) can b...
