Heat pipe residual heat recovery type drying machine

Abstract

The invention relates to a hot tube afterheat reclaiming drier and relates to the technical field of drying device. The lower part of a drying box is connected with an auxiliary box body inside of which is provided with a middle channel and the channels on the two sides, the middle channel is communicated with the bottom of the drying box, while the upper ends of the channels on the two sides are respectively communicated with the bottoms of the left interlayer and the right interlayer of the drying box, the channels on the two sides are communicated with the lower part of the middle channel; the inside of the auxiliary box body is distributed with a heat exchanging tube two ends of which are enclosed, a part of the heat exchanging tube is distributed in the middle channel while the other part is distributed in the channels on the two sides. The heat contained in the damp gas permuted in the material reaches the auxiliary box body though the bottom of the drying box, the heat exchanger is utilized to distill heat from the damp gas, and the heat is simultaneously used for preheating the drying medium so as to further reach that the energy can be logically utilized during the whole drying craftwork process with biggest of the heat efficiency during the craftwork process, thereby reaching the purposes of energy saving and wastage reducing.

Description

technical field [0001] The invention relates to the technical field of drying equipment. Background technique [0002] Almost all dryers that use hot air or other hot gas as the medium for drying have the problem of low thermal energy utilization of the hot and humid gas. A large amount of high-temperature humid gas is discharged into the atmosphere in vain. Although some gas recycling methods are used to reduce this loss, a lot of energy is still wasted in the operation of the equipment. At the same time, there are still thermal pollution of the environment. Contents of the invention [0003] The purpose of the present invention is to design a heat pipe waste heat recovery dryer that can fully recover waste heat and reduce heat pollution. [0004] The invention comprises a drying box with material inlet and outlet at both ends, the drying box is provided with left, right and upper interlayers, a steam heater and a condensed water heater are arranged in the upper interla...
