Energy-saving continuous drying equipment

Abstract

The invention relates to energy-saving continuous drying equipment. A heat-preservation baking oven is provided with a raw material inlet, a raw material outlet, and a steam heating mechanism for heating the air in the heat-preservation baking oven; a conveying mechanism is located in the heat-preservation baking oven, and a material feeding end and a material discharging end of the conveying mechanism are arranged close to the raw material inlet and the raw material outlet respectively; a damp-and-hot air exhaust waste heat recovery mechanism includes a waste heat recovery box and heat exchange tubes, a damp-and-hot air inlet, a damp air exhaust outlet, a fresh air supplement port, a fresh air outlet and a condensate water drainage outlet are formed in the waste heat recovery box, the damp-and-hot air inlet is communicated with an inner cavity of the heat-preservation baking oven through an air circulation fan, the outer walls of the heat exchange tubes are connected with a plurality of cooling fins, the damp-and-hot air inlet and a damp-and-hot air outlet are communicated through the heat exchange tubes, the heat exchange tubes are also communicated with the condensate water drainage outlet, the fresh air supplement port is communicated with the outside air through a pipeline, and the fresh air outlet is communicated with the inner cavity of the heat-preservation baking oven through the pipeline. The drying equipment is low in energy consumption, high in heat utilization rate and high in drying efficiency.

Description

technical field [0001] The invention relates to the field of dryers, in particular to an energy-saving continuous drying equipment. Background technique [0002] Dryers are widely used in food, feed, chemical, pharmaceutical, mining and other industries. During the drying process of materials, there are hot air flow type and radiation type. Heating is carried out so that the moisture of the material is continuously evaporated, so as to achieve the purpose of drying. Traditional dryers mostly only consider how to dry materials, but do not consider how to dry materials at the lowest cost. Their energy consumption is high, and the heat is directly discharged into the external atmosphere with the air, resulting in a large waste of resources. Contents of the invention [0003] The present invention aims at the deficiencies of the prior art and provides an energy-saving continuous drying equipment. [0004] In order to solve the above problems, the technical scheme adopted in ...
