Problems solved by technology

[0002] Drying of kelp particles usually uses a boiler to heat the air. The hot air is used to heat the kelp particles to evaporate the water in the particles. The heat energy in the hot air is only used once and then discharged. The humidity of the hot air increases slightly, but it does not Reaching saturation, direct hot air drying is a great waste of energy

specific Embodiment approach

[0018] The first-stage return air drying box 2 is connected in series with the front end of the heat radiation drying box 3, and the end of the heat radiation drying box 3 is connected in series with the gas hot air drying box 4, and all the inlets and outlets of the drying boxes are equipped with material feeding one-way doors 23. The kelp particles need to be dried for a period through the kelp preheating tank 11 . The kelp particles are sent to the primary return air drying box 2 through the entrance 1 of the kelp conveyor chain for secondary drying. Through the kelp conveyor chain, the kelp particles dried in the second stage are sent to the thermal radiation drying box 3 for three-stage drying, and the kelp particles after the three-stage drying are sent into the gas hot air drying box 4 through the kelp conveyor chain for drying. Four stages of drying, the dried kelp particles are sent out through the kelp conveyor chain outlet 24.

Abstract

The invention relates to a four-section thermal cycling kelp drying device using fuel gas as a heat source. The fuel gas burns to generate heat so as to dry kelp particles by two means which are heatradiation drying and hot-air drying separately. The hot air drying is divided into three parts: material drying with waste heat, heat radiation return air drying, and fuel gas hot air drying. The heatradiation drying is carried out by a fuel gas infrared heating plate, and a steel plate is heated by infrared radiation so as to dry materials in a heat radiation drying oven.

Description

technical field [0001] The invention relates to thermal cycle drying technology, in particular to the application of a kelp drying device, and belongs to the field of thermal energy step utilization. Background technique [0002] To dry kelp particles, boilers are usually used to heat the air, and the hot air is used to heat the kelp particles to evaporate the water in the particles. The heat energy in the hot air is only used once, and then it is discharged. The humidity of the hot air increases slightly, but it does not Reaching saturation, hot air direct drying is a great waste of energy. Contents of the invention [0003] The heat source of the four-stage thermal cycle kelp drying device is gas, and the heat generated by gas combustion dries kelp particles in two ways, namely heat radiation drying and hot air drying. Hot air drying is divided into three parts, namely waste heat material drying, heat radiation return air drying, and gas hot air drying. Radiation dryin...
