Dryer based on methanol heating

Abstract

A dryer based on methanol heating comprises a dryer body and a methanol heater. The methanol heater comprises a heat exchange cylinder, a heating pipe is arranged in the center of the heat exchange cylinder, a heat exchange cavity is formed between the heating pipe and the outer wall of the heat exchange cylinder, the upper end and the lower end of the heat exchange cavity are provided with an airinlet and an air outlet correspondingly, and a heat exchange medium enters and exits from a heat exchange opening and exchanges heat with the heat exchange cavity; a plurality of layers of catalyticcakes and heat storage cakes are stacked in the heating pipe, a fan and a methanol spray head are connected to the bottom of the heat exchange cylinder, the dryer body is provided with an air inlet pipe to be connected with an air outlet of the methanol heater, and further provided with an air outlet pipe to be connected with an air inlet of the methanol heater, and a ventilation device is arranged on the air inlet pipe or the air outlet pipe. The dryer has the beneficial effects that methanol catalysis heat generation is adopted by the dryer to provide heat for the dryer, so that a large amount of electric energy does not need to be consumed when the dryer works, and the electric load is favorably reduced.

Description

technical field [0001] The invention relates to a heater, in particular to a dryer based on methanol heating. Background technique [0002] In the field of drying, the samples are generally placed directly on the drying carrier frame or drying plate set up layer by layer, and the hot air flow sequentially dries the samples placed on the multi-layer samples in sequence from top to bottom or bottom to top. Dry. However, the traditional hot air flow is realized by electric heating, so it needs to consume a large amount of electric energy during its operation, resulting in high operating costs, so it is necessary to further improve it. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the prior art and provide a dryer based on methanol heating, which is simple in structure, easy to use, low in cost of use, and high in heat exchange efficiency. [0004] The object of the present invention is achieved in the following man...
