Device and method for drying clothes at low temperature through mechanical vapor recompression (MVR)

Abstract

The invention relates to a device and a method for drying clothes at low temperature through mechanical vapor recompression (MVR), and belongs to the field of energy conservation. The device comprises a shell (2), a roller (1) arranged in the shell (2) through a rolling bearing (6), and a sealing jacket (3), a compressor (4), a water discharge pump (5), an expander (7) and a gas-liquid separator (8) which are arranged on the heat-conducting wall surface of the roller (1), wherein the outlet of the roller (1) is connected with the compressor (4), the sealing jacket (3), the expander (7) and the gas-liquid separator (8) in turn; the gas-liquid separator (8) is provided with a gas phase outlet and a liquid phase outlet; the gas phase outlet of the gas-liquid separator (8) is connected with the inlet of the roller (1); the liquid phase outlet of the gas-liquid separator (8) is connected with the inlet of the water discharge pump (5); and the outlet of the water discharge pump (5) is connected with an external environment. The invention has the characteristics of low energy and water consumption, simple and compact process and wide applicable clothes range, and is particularly suitablefor the energy conservation and emission reduction transformation of the conventional clothes drying process.

Description

technical field [0001] The invention relates to a mechanical steam recompression low-temperature clothes drying device and method, belonging to the field of energy saving. Background technique [0002] With the acceleration of the pace of modern life, laundry devices integrating laundry, dehydration and drying have more and more broad development prospects. Especially for some occasions where the relative humidity of the ambient air is high, it is particularly important to dry clothes. At present, conventional clothes drying mainly uses electric heating to heat the air, and a fan is used to send the hot air into the drying drum to speed up the evaporation of water in the clothes. Then use ambient cold water to pass through the water-humid air heat exchanger to condense the high-temperature humid air evaporated from the clothes in the drum. Part of the moisture in the high-temperature humid air is condensed by the ambient cold water in the heat exchanger, and finally the con...

AI Technical Summary

Problems solved by technology

However, this method consumes a lot of electricity, and it needs a large amount of cooling water to condense high-temperature and humid air in the heat exchanger.

In addition, the increase of drying temperature is difficult to meet the requirements of a large number of heat-sensitive clothes, which makes the range of clothes suitable for the existing high-temperature drying process very narrow

It can be seen that the existing clothes drying process has the problems of high energy consumption, high water consumption and narrow adaptability of clothes
