Problems solved by technology

[0003] As we all know, in the automobile painting workshop, the structure of the hot air circulation system in the drying room is currently used. The high-temperature flue gas is sent to several heat exchangers connected in series by the heating incinerator through the pipeline. The resistance of the heater, so the resistance that the flue gas needs to overcome is the sum of the resistance of several heat exchangers and pipes. In addition, during the start-up process of the cold furnace, the traditional heating time of the drying room is relatively long. Since this equipment is long-term operation, Therefore energy waste is long-term

Abstract

The invention relates to the technical field of a heating system or device, particularly to a parallel-serial type drying and heating system. According to the parallel-serial type drying and heating system, the resistance of a heat exchanger system is reduced, the demands for pressure of a flue gas induced draft fan are reduced, the energy is reasonably distributed, the heating up time for starting of a black furnace of a drying room is reduced, and the energy consumption is reduced. The parallel-serial type drying and heating system comprises a drying room body, a heating combustion furnace, a heat exchanger group, an induced draft fan and a waste heat exchanger, wherein the drying room body comprises a drying room first heating area, a drying room second heating area, a drying room first heat preservation area and a drying room second heat preservation area; the heat exchanger group comprises a first heat exchanger, a second heat exchanger, a third heat exchanger and a fourth heat exchanger; the heating combustion furnace is communicated with the first heat exchanger and the third heat exchanger through a first communicating pipe; the heating combustion furnace is communicated with the second heat exchanger and the fourth heat exchanger through a second communicating pipe; an air inlet end of the first communicating pipe is communicated with an air inlet end of the second communicating pipe; and a communicating position of the air inlet ends is provided with a distribution valve.

Description

[0001] technical field [0002] The present invention relates to the technical field of heating systems or devices, in particular to a hybrid drying and heating system. Background technique [0003] As we all know, in the automobile painting workshop, the structure of the hot air circulation system in the drying room is currently used. The high-temperature flue gas is sent to several heat exchangers connected in series by the heating incinerator through the pipeline. The resistance of the heater, so the resistance that the flue gas needs to overcome is the sum of the resistance of several heat exchangers and pipes. In addition, during the start-up process of the cold furnace, the traditional heating time of the drying room is relatively long. Since this equipment is long-term operation, Therefore, energy waste is long-term. Contents of the invention [0004] In order to solve the above-mentioned technical problems, the present invention provides a heat exchanger system wi...
