High temperature heat pump-based waste heat recovery curing barn

Abstract

The invention relates to a high temperature heat pump-based waste heat recovery curing barn comprising a body, a high-temperature heat pump unit disposed on the left of the body, an evaporator, a condenser, a conveying line, a recovery line, fan blades and a waste heat recovery valve hole. The evaporator and the condenser are disposed within the high-temperature heat pump unit; the conveying line and the recovery line connect the evaporator and the condenser; the fan blades are disposed on the left of the evaporator; the right of the evaporator is provided with the waste heat recovery valve hole. The conveying line is provided with a liquid storage tank and a throttle device sequentially from left to right; the recovery line is provided with a compressor. post-curing waste heat generated by the barn is subjected to moisture discharge and recycling, curing heat is provided for the barn, heating power consumption of a main unit is reduced, operational efficiency ratio of the main unit is increased, the waste heat is automatically recycled, moisture is automatically discharged, heat generation of the evaporator is increased, efficiency ratio is increased, energy is thus saved, the fact that direct emission of heat to the atmosphere influences weather balance is avoided, and the barn is environment friendly, simple to use, handy and practical.

Description

technical field [0001] The invention relates to a tobacco flue-curing room, in particular to a high-temperature heat pump waste heat recovery tobacco flue-curing room used in the process of baking tobacco, pickled products, etc. to recycle the remaining heat. Background technique [0002] Traditionally, the commonly used equipment for baking tobacco and pickled products is a coal curing room. The heat generated during the baking process is directly discharged to the outside, which not only causes waste heat waste, but also has a low heat recovery rate of waste heat, and The heat is emitted directly into the atmosphere, directly affecting the climate balance in the air. [0003] As human beings become more and more aware of environmental protection, the sustainable development of industrial production must be based on energy conservation, environmental protection, without affecting or destroying the ecological balance and climate balance. For example, the Chinese patent numb...

Problems solved by technology

For example, the Chinese patent number is "201110142858.8", and the patent name is "an automatic flue-cured tobacco room". Its design concept utilizes environmental energy, and uses wind energy to drive some workpieces to rotate to achieve the purpose of energy saving. It can also complete the drying of tobacco. Drying, but it takes a long time to dry, resulting in low efficiency of drying tobacco, and the waste heat generated by the flue-curing room cannot be recycled.

[0004] Another example is that the Chinese patent number is "201220283759.1", and the patent name is "a flue-cured tobacco room," which mainly uses carbon fiber electric heating elements to heat the tobacco instead of the traditional way of burning coal. The improvement of the heating method makes the baking process The heat conversion rate reaches 98%, but it does not recycle the waste heat generated by the flue-cured room to realize the recycling of heat energy, energy saving and environmental protection.
