Embodiment 1

[0058] A method for processing biomass solid briquette fuel, the specific operation steps are as follows:

[0059] (1) Combustible gas preparation of wheat straw raw materials: process wheat straw raw materials into wheat straw powder with a particle size of 1-2mm, and fill them into the first-level straw storage bin and the second-level straw storage bin; store the first-level straw The wheat straw powder with a particle size of 1-2 mm in the warehouse is transported to the first biomass gasifier through the scraper conveyor, and the wheat straw powder is gasified by the first-stage straw storage warehouse to obtain combustible gas, and the combustible gas undergoes heat exchange through tubes The temperature of the device is lowered and sent to the first gas heating furnace and the second gas heating furnace;

[0060] Among them, the working conditions of the biomass gasifier are: the feed rate of straw powder is 1t / h, the gasification temperature core is 1000°C, the reactio...

Abstract

The invention discloses a low-energy consumption and high-calorific value formed fuel processing device and a method thereof. The device comprises a first-stage straw storage bin, a second-stage strawstorage bin, a coffee ground storage bin, a first fuel heating furnace, a second fuel heating furnace and a pregelatinized starch tank, wherein the first-stage straw storage bin is connected with a biomass gasifying furnace, and an outlet of the biomass gasifying furnace is connected with the first fuel heating furnace and the second fuel heating furnace, respectively; the second-stage straw storage bin is connected with the first fuel heating furnace through a first chain grate stoker; the coffee ground storage bin is connected with the second fuel heating furnace through a second chain grate stoker; and the fuel heating furnace, the second fuel heating furnace and the pregelatinized starch tank are connected with an extrusion forming machine through the same mixing stirrer, and an outlet of the extrusion forming machine is connected with a formed fuel storage bin. According to the device, a low-energy consumption and high-calorific value solid formed fuel can be obtained, so that the utilization cost of a biomass energy source is lowered, and the development and the application of a biomass utilization technique are promoted.

Description

technical field [0001] The invention relates to a treatment device and method for biomass mixed solid briquette fuel. Background technique [0002] For a long time, traditional fossil fuels have been the main energy consumed by human beings, and have made great contributions to the development and improvement of society, economy and living standards. However, since fossil resources such as coal, oil, and natural gas are non-renewable resources, and there are problems such as serious environmental pollution and high processing equipment costs in the process of combustion and conversion, the development and utilization of renewable energy is currently one of the current research hotspots. . Biomass energy is an important renewable energy source. my country is rich in biomass resources. It is estimated that about 460 million tons of standard coal biomass resources can be used as energy every year, of which agricultural straw accounts for more than 50% of the total. In additi...
