Abstract

The invention relates to a system closed loop type sludge dehumidifying and drying system which comprises a box body. The box body is divided into a sludge drying area and a dehumidifying heating areaby a partition plate. The system is characterized in that the dehumidifying heating area is provided with at least three air ducts: a primary air duct, an inner balance first air duct and an inner balance second air duct, wherein the primary air duct is successively provided with a pre-cooling system evaporator, a primary humid extracting system evaporator and a pre-cooling system auxiliary condenser from the air inlet direction to the air outlet direction; a pre-cooling system primary condenser is arranged on the inner balance first air duct; and a primary humid extracting system condenser is arranged on the inner balance second air duct. The system has the advantage that a stable and reliable closed loop operation of the whole drying system can be achieved without frequent external heatdissipation.

Description

technical field [0001] The invention relates to a drying system, in particular to a system closed-loop sludge dehumidification and drying system. Background technique [0002] With the strengthening of the country's economic strength and the improvement of national environmental protection awareness, the urban sewage treatment industry has developed rapidly, and the output of urban sludge and enterprise sludge has increased day by day, and the disposal, development and utilization of sludge have increasingly attracted people's attention. [0003] The traditional treatment method for sludge is the drying equipment using the condensation method. Its working principle is: the basic principle of the drying equipment using the condensation method in the industry is similar. Usually, the humid air from the drying room is cooled and dehumidified through the refrigeration system. When the wet air When passing through the evaporator, the evaporator is used to evaporate and absorb hea...
