Rotary-type thermal superconductive dryer can for heating by directly using energy without steam and conduction oil

Abstract

The invention relates to a rotary-type thermal superconductive dryer can for heating by directly using energy without steam and conduction oil. An outer dryer can (1), an inner dryer can (3), a smoke-in baffle plate (7) and a smoke-out baffle plate (9) are welded into an inner cavity of the inner dryer can (11) and an annular cavity; the annular cavity formed by the outer dryer can (1) and the inner dryer can (3) is a vacuum cavity which is internally provided with a solution absorption core (2); the solution absorption core (2) is filled with working media (8); a fuel conveying barrel (5) passes through a first hole (12) and is arranged in the inner cavity of the inner dryer can (11); the fuel conveying barrel (5) is provided with a combustor (4); a smoke exhaust pipe (10) passes through a second hole (13) and is communicated with the inner cavity of the inner dryer can (11); the inner cavity of the inner dryer can (11) is internally provided with a drum-type smoke guider (6) which is connected with the smoke exhaust pipe (10). By adopting radiation heating, the invention reduces the production cost for enterprises, can greatly reduce energy saving and exhaust emission by more than 50% and realize low carbon.

Description

technical field [0001] The invention belongs to a drying equipment, in particular to a rotary thermal superconducting drying cylinder which is directly heated by energy without using steam or heat-conducting oil. Background technique [0002] At present, the paper industry, textile printing and dyeing industry, plastic film industry, chemical fiber heat setting industry, and the rotary drying industry of various granular and powdery materials, such as the drying of sawdust in the building materials industry, the drying of granular grain, and the slag in the cement industry 1. The drying of loess, shredded tobacco, and drying of granular materials such as quartz sand all use steam boilers to supply steam, or use heat-conducting oil furnaces, and the heating oil circulates to heat the drum dryer to complete the drying of the products. Taking paper machine drying as an example, if the thermal efficiency of the steam boiler is 80%, and the thermal efficiency of the steam and the...

Problems solved by technology

Taking paper machine drying as an example, if the thermal efficiency of the steam boiler is 80%, and the thermal efficiency of steam and drying cylinder is 50%, plus the inevitable running, popping, dripping, and leaking of the boiler, the auxiliary energy such as induced wind and dust removal, water pump, etc. As well as water resources, etc., the effective drying paper energy of the total energy is at best less than 30%, and most of the energy is wasted

These industries are large energy-consuming and high-polluting industries, which not only waste resources, but also pollute the environment, and the production costs of enterprises are high.
