Three-dimensional air supply heat pump dryer

Abstract

The invention discloses a three-dimensional air supply heat pump dryer. The three-dimensional air supply heat pump dryer comprises a heat pump chamber and a drying chamber; a total heat exchanger, a heat pipe, an inner evaporator, an inner condenser, an outdoor heat exchanger and a fan arranged in an exhaust port of the heat pump chamber are arranged in the heat pump chamber; an intake surface andan exhaust surface of the inner evaporator communicate with a hot air outlet B and a cold air inlet C of the total heat exchanger to cool, condense and dehumidify hot air, exhausted by the hot air outlet B of the total heat exchanger, as cold air to return to the total heat exchanger; the heat pipe consists of a heat absorbing section and a heat releasing section arranged in the hot air outlet Band the cold air inlet C of the total heat exchanger; an intake surface and an exhaust surface of the inner condenser communicate with a cold air outlet D of the total heat exchanger and an exhaust port of the heat pump chamber; a drying inner cavity communicating with an intake way and an air return way is formed in the drying chamber; and a penetration air supply way and a parallel air supply way are arranged in the drying inner cavity.

Description

technical field [0001] The invention relates to the technical field of heat pump drying, in particular to a three-dimensional air supply heat pump dryer. Background technique [0002] Most of the traditional drying techniques in my country use electric heating, coal-fired gas boilers and other heating methods to heat and dry the indoor air and discharge the moisture contained in the material to the outside, while supplementing part of the drying fresh air. This traditional heating method not only pollutes the air, but also wastes energy, which is not conducive to the sustainable development of the national economy. In addition, most of the high-temperature and high-humidity air in the existing dryer is directly discharged through the air outlet, which leads to serious waste of heat and lack of heat recycling. Secondly, the air supply mode in the drying space of the existing dryer is single, and the air supply mode cannot be switched and adjusted, resulting in the problem th...

Problems solved by technology

This traditional heating method not only pollutes the air, but also wastes energy, which is not conducive to the sustainable development of the national economy.

In addition, most of the high-temperature and high-humidity air in the existing dryer is directly discharged through the air outlet, which leads to serious waste of heat and lack of heat recycling

Secondly, the air supply mode in the drying space of the existing dryer is single, and the air supply mode cannot be switched and adjusted, resulting in the problem that some parts of the dried materials are not dried properly. Azimuth three-dimensional air supply drying is a technical problem that technical personnel in the industry urgently need to solve
