Problems solved by technology

The wet method can be divided into the spray method and the bubble blowing method. The tar in the biomass gas is taken away with water. The water washing method is easy to entrain the liquid mist in the process of removing the tar. The equipment, liquid recovery and circulation device are huge, and will also produce Secondary pollution problem; the dry method uses an adsorbent to separat

[0030] First embodiment

[0031] Please refer to figure 1 This embodiment provides a tar gasification cycle device, which includes a separator 10 for connecting to the gasifier 20, a tar gasification pipe 30 for tar generated by the gasification furnace 20, and a filter device 40.

[0032] Further, please refer to the attached figure 2 The gasification furnace 20 includes a drying chamber 211, a pyrolysis chamber 213, and a gasification chamber 215. The material enters the gasification furnace 20 from the inlet 200, passes through the drying chamber 211, the pyrolysis chamber 213, and the gasification chamber 215 in sequence. Among them, incomplete combustion mixed gas will be generated in the drying chamber 211 and the pyrolysis chamber 213 , Including tar and water vapor.

[0033] Further, please refer to the attached image 3 , The tar gasification cycle device includes a separator 10. The separator 10 is mainly used to re-use the incompletely combusted gas generated in the dry...

Abstract

The invention relates to the technical field of solid fuel gasification and gasification collection and utilization, and provides a tar gasification circulation device, which includes a separator for connecting a gasification furnace, a tar gasification pipe and a filtering device. The tar gasification passage is provided with a first liquid inlet, a first liquid outlet for communicating with the drying chamber of the gasification furnace, and a second gas outlet for communicating with the gasification chamber of the gasification furnace, and the flue gas passage is provided with The first flue gas outlet is connected to the filter device. The tar produced by the gasifier can be recycled to the gasifier, where the tar is repeatedly cracked. The separator is provided with a first gas inlet, a first exhaust port and a first liquid discharge port, the first gas inlet is used to communicate with the drying chamber and the pyrolysis chamber provided in the gasification furnace, and the first exhaust port is used to communicate with the The gasification chamber provided in the gasification furnace is connected, and the first liquid discharge port is connected with the first liquid inlet. The separator filters and separates the mixed gas produced in the gasifier, removes the moisture in the mixed gas, and increases the calorific value of the gas.

Description

technical field [0001] The invention relates to the technical field of solid fuel gasification and gasification collection and utilization, in particular to a tar gasification cycle device and a gasification system. Background technique [0002] Garbage is solid waste generated in human daily life. Due to the large amount of discharge, complex and diverse components, and polluting properties, it needs to be disposed of properly. Otherwise, it will pollute the environment, affect environmental sanitation, and waste resources. The treatment of garbage is to make the garbage harmless. The most widely used treatment methods in today's society are landfill and incineration. The effect of landfill is very slow and occupies a large area, which is easy to cause secondary pollution to groundwater; incinerators and gasification furnaces can effectively reduce the amount of garbage, but the air pollution caused by incineration and gasification of garbage is a serious problem. big prob...
