Four methods to effectively reduce the energy consumption of the Wood Chip Dryer

How to improve the drying efficiency of the dryer and reduce the cost of thermal energy consumption has gradually attracted the general attention of cement companies.Wood Chip Dryer In order to complete the increase in production and energy saving of the drying system, when the design of the drying line is stopped,Wood Chip Dryer it is necessary to seek a reasonable configuration of the drying system; for the established consumption line,Wood Chip Dryer new technology should be used to stop the drying line from perfecting the support. Contribute four ways to effectively reduce the energy consumption of the dryer!

Local exhaust gas circulation, due to the application of local waste heat in the local exhaust gas,Wood Chip Dryer the thermal efficiency of the dryer has improved, but with the increase in the amount of exhaust gas circulation,Wood Chip Dryer the moisture content in the hot air increases, and the dryness rate will decrease,Wood Chip Dryer making the humidity The increase in the dry time of the material leads to an increase in the cost of the drying equipment. Therefore,Wood Chip Dryer there is a good amount of waste gas circulation. Ordinary exhaust gas circulation is 20%--30%, other ways of self-use of hot exhaust gas: in addition to the above energy-saving method of applying local exhaust gas circulation to recover heat,Wood Chip Dryer indirect heat exchange equipment can also be used from the exhaust gas of the drying equipment Energy recovery methods such as heat recovery,Wood Chip Dryer commonly used heat exchange equipment include heat wheel heat exchangers, plate heat exchangers, heat pipes, heat pumps,Wood Chip Dryer etc.

Reduce the loss of heat during the drying process. Generally speaking,Wood Chip Dryer the heat loss of the dryer will not exceed 10%. If the insulation is suitable for large and medium-sized consumer installations,Wood Chip Dryer the heat loss is about 5%. Therefore, do a good job in the insulation of a boring system, but it is not that the thicker the insulation layer,Wood Chip Dryer the better. It should be a good insulation layer thickness. In order to avoid the leakage of the dry system,Wood Chip Dryer the air blower and the induced draft fan are generally used in series, and the system is operated at a zero pressure through reasonable adjustment,Wood Chip Dryer which can prevent the convection dryer from drying due to the leakage of dry media or the leakage of ambient air.Wood Chip Dryer The thermal efficiency of the machine drops.

Improve inlet temperature and reduce exhaust gas temperature: Generally speaking,Wood Chip Dryer the energy consumption of convection dryer is mainly composed of two parts: evaporating moisture and exhaust gas,Wood Chip Dryer and then a part accounts for about 15%-40%, some up to 60% Therefore,Wood Chip Dryer reducing the temperature of the exhaust gas of the drying equipment is limited by two factors: one is to ensure the product moisture content (the temperature of the exhaust gas is too low,Wood Chip Dryer the product moisture content increases, and the requested product moisture content is not met); second,Wood Chip Dryer the exhaust gas enters the cyclone When the separator or bag filter is used, make sure its temperature is 20-60℃ higher than the dew point.
