Problems solved by technology

At present, there are a variety of thermal regeneration methods and devices at home and abroad, but there are still shortcomings: the carbon loss rate is relatively large, between 5% and 16%; the adsorption capacity will decrease significantly after regeneration; The environment causes secondary pollution; energy consumption is high, overall operating costs are high, and economic benefits are low
[0007] (1) Low service life, low reliability, difficult parts replacement and poor maintainability;
[0008] (2) General energy-saving effect;
[0009] (3) Inconvenient transportation;
[0010] (4) The problem of thermal expansion and cold contraction of the material pipe has not been fundamentally resolved;
[0011] (5) High equipment cost

Abstract

The invention discloses a powder activated carbon modular combination type regenerative furnace. The powder activated carbon modular combination type regenerative furnace comprises a plurality of monomer regenerative furnaces, supporting blocks, material falling pipes, base and a motor; each monomer regenerative furnace can realize heating and conveying of a material; the monomer regenerative furnaces are stacked from top to bottom; every two monomer regenerative furnaces are separated from each other by using the supporting blocks and the material falling pipes to form an arch-shaped material feeding trough; the material feeding trough is integrally mounted on the base; spiral conveyors are arranged in the monomer regenerative furnaces and are driven to rotate through the motor, so that the vertically adjacent two spiral feeding conveyors are opposite in material feeding directions; therefore, powder activated carbon forms a flow state in the modular combination type regenerative furnace. The powder activated carbon modular combination type regenerative furnace is a converter, which is good in energy saving effect, low in cost, convenient to convey, long in overall life, high in reliability, convenient to replace, high in maintainability, good in modular structure division and strong in monomer regenerative furnace arbitrary combinability and can regenerate activated carbon continuously in large batches.

Description

technical field [0001] The invention belongs to the technical field of industrial equipment and technology, and in particular relates to a modular combined converter for regeneration of powdered activated carbon. Background technique [0002] Powdered activated carbon (Activated Carbon, AC) is a kind of adsorption material with very developed pore structure, large specific surface area, non-toxic and tasteless, and has a strong ability to adsorb molecules. Food, environmental protection and many other fields. In terms of environmental protection, activated carbon adsorption is widely used in the purification of polluted water sources and the advanced treatment of urban sewage and industrial wastewater, and is one of the important means of treating organic wastewater. [0003] The production cost of powdered activated carbon is high, and the waste of saturated activated carbon not only causes waste of resources, but also causes secondary environmental pollution. Therefore, f...
