One-drum-type dehumidifying and drying regenerating device and relevant dehumidifying and drying regenerating process

Abstract

The invention relates to a one-drum-type dehumidifying and drying regenerating device, wherein a drying drum is respectively connected with a drying filter and a drying changeover valve through gas circuits; the drying filter, a first valve, a drying regenerating fan, a second valve, a one-drum-type dehumidifying source, a drying regenerating heating pipe and the drying changeover valve are connected sequentially through gas circuits; a gas circuit which connects the first valve with the drying regenerating fan is connected with a gas circuit, which connects the drying regenerating heating pipe and the drying changeover valve, through a third valve; the regenerating filter is connected with a gas circuit, which connects the drying regenerating fan and the second valve, through a fourth valve; and a gas circuit which connects the second valve with the one-drum-type dehumidifying source is connected with a regenerating changeover valve. The invention also provides a relevant dehumidifying and drying regenerating process. The one-drum-type dehumidifying drying regenerating device provided by the invention is skilful in design and simple in structure; one heating pipe is used for drying and regenerating so that the utilization rate of the heating pipe is improved, the cost and the energy consumption are reduced and the occupied space is smaller; and the device has excellent performance and is suitable for large-scale popularization and application.

Description

technical field [0001] The present invention relates to the technical field of drying devices, in particular to the technical field of dehumidification, drying and regenerating devices, and specifically refers to a one-tube dehumidification, drying and regenerating device and related dehumidification, drying and regenerating processes. Background technique [0002] At present, there are two main types of dryers in the plastic auxiliary equipment industry: hot air dryers and dehumidification dryers. Among them, dehumidification dryers traditionally use dehumidification sources, with drying, regeneration, and cooling process control respectively, and drying and regeneration fans are used on the equipment. In addition, it is equipped with conveying device and other functions. [0003] Among them, the existing dehumidification dryer has some disadvantages: 1. The regeneration and drying of the dehumidification source use a heating tube alone, which has a large space and high co...

Problems solved by technology

[0003] Among them, the existing dehumidification dryer has some disadvantages: 1. The regeneration and drying of the dehumidification source use a heating tube alone, which has a large space and high cost; 2. A cooling source is required during the cooling process, and the customer must provide a cooling water source; 3. The air supply is internal circulation, which is easy to cause fluctuations in drying temperature

Its disadvantages are: 1. The same dehumidification source requires two heating pipes for drying and regeneration respectively, which consumes a lot of energy and takes up a lot of space; 2. The cooler at the drying return air is water-cooled and needs external cooling water; 3. , It is necessary to supplement the drying internal circulation during the secondary transportation, which is likely to cause fluctuations in the drying temperature
