Vertical Dryer

Vertical dryer

Vertical dryer, also known as vertical dryer, in order to solve the problem of large investment, large area and high failure rate of horizontal dryer, the equipment uses low air volume and gravity principle, through research and development design, industrial test, product upgrading, large-scale operation and other stages, lasting several years and successful products.

Commonly used materials: silica, pulverized coal, raw coal, sludge, coke, blue carbon, calcium carbide, silicon manganese, etc

Common heat sources and supporting equipment: natural gas, coal; It is provided by the boiling furnace and can use the tail gas of the blast furnace such as lime kiln and calcium carbide furnace.

Vertical dryer product introduction

The vertical dryer produced by Zhengmine machine is suitable for the drying treatment of industrial silicon production fine coal washing, blue carbon and other materials. The equipment adopts vertical equipment steel structure shell, lined with insulation material for heat preservation, multi-layer high-temperature castings are used in the kiln, overlapping with each other, and several groups of vibration, interception, temperature control and intelligent control systems are set up in the upper, middle and lower related components. Water vapor and smoke are collected and removed by the induced draft fan cyclone dust collector.

Outstanding advantage

1, compared with horizontal dryer, less investment, small footprint, energy consumption and operating costs are greatly reduced;

2, equipment operation and maintenance is simple, continuous operation, saving manpower and labor;

3, high utilization rate of equipment thermal efficiency, large capacity, more use of environmental protection;

4, the equipment adopts vertical equipment steel structure shell, lined with thermal insulation material.

Working principle

The technology of vertical dryer is to control the flow rate and residence time of the material in each area of the dryer, so that the hot gas and the material are fully convection, radiation, conduction heat exchange, so that the material is dispersed as much as possible in the dryer, so as to improve the contact area between the hot gas and the material. At the same time, the micro-computer software technology of material drying parameter optimization was adopted to carry out online detection of material moisture and gas temperature in the three regions of pre-tropical zone, drying zone and drying zone, and online adjustment was made to system parameters such as heating capacity, induced air volume, secondary hot air distribution and heating capacity, material intercepting capacity and retention time, so as to achieve dynamic optimization and balance of the system. Improve system heat efficiency.
