Environment-protection husk absorbent charcoal activation furnace

Abstract

The invention belongs to activated carbon production equipment, in particular to an environment-friendly pericarp-activated carbon activation furnace which consists of a furnace body device (1), an uplink flue device (2), a furnace basis device (4), a flue main switch valve device (5), a waste gas, steam, and an air switching valve device (6), a flue device (7) and a chimney device (8). The furnace body device (1) is provided with two adjacent semi-furnaces, and each semi-furnace is provided with 80 product channels (28) and horizontal air channels (29) which are bedded by eight types of abnormity refractory bricks, including a No.5 clay brick (30), a No.6 clay brick (31), a No.7 clay brick (32), a No.7A clay brick (33), a No.8 clay brick (34), a No.9 clay brick (35), a No.11 clay brick (36), and a No.12 clay brick (37). The product channels (28) are designed into arc shapes. The activation furnace with small size and less product channels, high yield and less investment can reduce material consumption and improve the temperature and the pressure of the furnace; in addition, the efficacy of the invention can be increased significantly for matching the equipment with less investment and low energy consumption.

Description

technical field [0001] The invention belongs to activated carbon production equipment, in particular to an environment-friendly shell activated carbon activation furnace. technical background [0002] Activated carbon is an important material in various industries and environmental protection industries. The demand at home and abroad is increasing day by day, among which activated carbon from shells is particularly in short supply. In the late 1950s and early 1960s, my country introduced the Sleep coal-based activation furnace from the former Soviet Union. Because of this The investment in the furnace was too large. At the end of the 1960s, my country designed the 288-type activation furnace, which specializes in the production of granular activated carbon activation furnaces that use fruit shells as raw materials. This furnace is in the leading position in the world in technology and has been exported to Thailand, Vietnam, In Sri Lanka and other Southeast Asian countries, the...

[0002] Activated carbon is an important material in various industries and environmental protection industries. The demand at home and abroad is increasing day by day, among which activated carbon from shells is particularly in short supply. In the late 1950s and early 1960s, my country introduced the Sleep coal-based activation furnace from the former Soviet Union. Because of this The investment in the furnace was too large. At the end of the 1960s, my country designed the 288-type activation furnace, which specializes in the production of granular activated carbon activation furnaces that use fruit shells as raw materials. This furnace is in the leading position in the world in technology and has been exported to Thailand, Vietnam, In Southeast Asian countries such as Sri Lanka, the disadvantages of this kind of furnace are complex structure, large investment, long construction period, strict operating conditions, high energy consumption, low output, high product cost, and environmental pollution.
