Product Name: SGL series water-cooled drum slag cooler

SGL series water-cooled drum slag cooler is a kind of special equipment for dry cooling and conveying the high temperature slag of circulating fluidized bed boiler and fluidized bed boiler with general industrial water as heat exchange medium. While absorbing the advantages of various slag coolers in the current market, the equipment solves a series of problems such as high failure rate, large amount of maintenance, short life cycle and high slag temperature in the use of similar products, greatly reducing the number of downtime and maintenance time, and effectively ensuring the continuous and stable operation of the equipment.

SGL series water-cooled drum slag cooler is mainly composed of spiral blade, inner and outer sleeve, feed and exhaust device, water inlet and outlet device, transmission device and base. When the drum is driven and rotated by the driving device, the high-temperature slag discharged from the boiler is guided forward by the spiral blade in the sleeve, the cooling water continuously and evenly passes through the sleeve interlayer and hollow blade, and the cooling air also continuously reversely passes through the sleeve, so that the slag gradually cools down.

The outstanding features of SGL series water-cooled drum slag cooler are as follows:

(1) Keep slag active: dry cooling is adopted to completely avoid water slag contact. Keep the activity of slag, make the headache slag produced by boiler become cement and building material additive with good activity.

(2) High thermal efficiency, wide range of slag removal temperature (40 ℃ ~ 220 ℃);

(3) The whole sleeve is used to push the material, the spiral blade and the cylinder have no relative movement, the structure is simple, the whole machine has high life, low power consumption and low noise;

(4) Excellent environmental protection and economic performance: there is no special requirement for cooling water. Circulating cooling water of power plant or general industrial water can be used as cooling water without desalting and softening, which can reduce capital construction investment and operation cost.

(5) The speed of continuous slag removal can be adjusted continuously in a large range according to the amount of slag. It is beneficial to stabilize the boiler bed pressure, keep the thickness of combustion layer and reduce the carbon content of slag.

(6) Because the cooling water discharge pipe is outside the drum, the drum is safe, reliable and easy to maintain;

(7) It can be equipped with cooling water overtemperature alarm, water cut-off shutdown (and alarm), overpressure relief and other safety protection.
