Embodiment Construction

[0014] A high-efficiency furfural waste residue boiler as shown in the figure is a steam boiler with furfural waste residue as fuel. It is mainly designed for furfural industrial wastewater treatment. The steam it produces is not limited to furfural industrial wastewater treatment, but can also be used as a conventional industrial boiler. The furnace adopts a fixed grate 15. The bottom of the fixed grate 15 is a primary air supply port 16, and the top of the fixed grate 15 is a furnace 11. The four corners of the base of the furnace 11 are blocked during masonry to prevent uneven air distribution on the grate surface. The furnace 11 is a closed blast furnace with a small cross-sectional area. One corresponding side of the furnace 11 is the water cooling wall 23 connected with the upper and lower headers 10 and 14 , the other corresponding side is the furnace wall, and the shorter side of the furnace wall is the folded smoke wall 13 . The bottom of the furnace 11 is provided ...

Abstract

The invention provides a high efficiency boiler burning furfural waste residue used in matching with the processing of furfural industrial wastewater, which is characterized in that: the boiler is composed by arranging a steam heater in a retrograde flue and positioning a smoke obstruct wall capable of adjusting smoke flux at the entrance of the retrograde flue. The invention takes the furfural industrial waste residue as the fuel and then uses the steam generated to process the furfural industrial wastewater, which is one of the key equipments for realizing zero-wastewater emitted in furfural production,; therefore, the invention belongs to the circulating economic projects featuring environmental protection and energy-saving as well as economic and practical and is characterized in automatic fuel drying, negative loading and cyclone-combustion, which has the advantages of compact and rational structure, novel and unique concept, steady and reliable performance, high temperature in hearth, utilizing rate for smoke-gas and heating efficiency in boiler, thereby effectively lowering the release of dust, reducing the pollution of environment and preventing from dirtying and coking as well as having safe and reliable operation, etc.

Description

Technical field: [0001] The invention relates to a steam boiler using furfural waste residue as fuel, in particular to a steam boiler for burning furfural waste residue which is matched with furfural industrial wastewater treatment. Background technique: [0002] my country is the country that mainly produces furfural and exports furfural rough processed products. Due to the abundant raw materials for furfural production in my country, the furfural industry has developed by leaps and bounds in recent years, the scale has continued to expand, and the output has also continued to increase. However, while the furfural industry in my country continues to grow and develop, it ignores the protection of the ecological environment. In the furfural production process, each enterprise discharges a large amount of industrial wastewater, and the wastewater under the tower of furfural enterprises contains a large amount of COD, BOD, etc. other pollutants. These waste water will cause ser...
