Waste heat fan heater and working method thereof

Abstract

The invention discloses a waste heat fan heater. The waste heat fan heater is characterized in that the waste heat fan heater comprises a fan, a heater and a heat exchanger; an air inlet of the heater is communicated with an air outlet of the heat exchanger, and an air outlet of the heater is communicated with an air inlet of the fan; the heat exchanger comprises a shell and an airflow channel, and an oil inlet, an oil outlet, an air inlet and an air outlet are formed in the shell; and air flow channels are evenly distributed in the shell, a heat flow channel is formed between every two adjacent air flow channels, inlets of the air flow channels are communicated with the air inlet, outlets of the air flow channels are communicated with the air inlet of the fan, inlets of the heat flow channels are communicated with the oil inlet, and oil outlets of the heat flow channels are communicated with the oil outlet of the shell. Waste heat is utilized, energy is saved, and the energy consumption is about 2-10% of that of an existing pure electric fan heater under the condition that the waste heat can be completely utilized to meet the requirements for the temperature and the flow of warm air.

Description

technical field [0001] The invention relates to the field of waste heat utilization, in particular to a waste heat heater and a working method thereof. Background technique [0002] In the production process of the enterprise, some mechanical equipment produces liquid with a temperature of 60-150°C or gas with a temperature of 90-280°C during the working process. In this paper, this part of the higher liquid or gas is called thermal fluid. At present, this part of the thermal fluid is generally cooled by cooling medium such as circulating cooling water or ground air, and then the cooling medium is directly or indirectly discharged to the ground or the atmosphere; in this process, the heat of the thermal fluid is basically not recycled; resulting in a certain Energy waste. Therefore, in order to solve the above-mentioned problems, a new device is needed to effectively utilize the energy. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the p...
