Hot conflux main pipe residual heat reclamation and utilization system using gas medium as hot source

Abstract

The invention relates to a thermal confluence bus-piping waste heat recovery and utilization system, whose thermal source is air medium. It is characterized in that at least two thermal air sources are connected with the channel of thermal air source respectively; each channel of thermal air source is connected one way of three-way wind door; another channel of three-way wind door is connected with the bus pipe of thermal confluence by connecting pipes; the bus pipe of thermal confluence is connected with the waste heat recovery device; the third way of three-way wind door is connected with by-pass channel; the protection device of generating device of thermal air source can be assigned on the channel of thermal air channel directly; the control equipment of thermal confluence is connected with the generating device of thermal air source, the three-way wind door and controlling and measuring component on the waste heat recovery and utilization device by control circuit. The merit of invention is that multiple thermal air sources are combined to enter into a waste heat recovery and utilization device so that waste recovery is realized easily and it is provided with high recovery efficiency, compact structure, small occupied area, easy assignment, easy running and maintenance and few spare parts.

Description

technical field [0001] The invention relates to a waste heat recovery and utilization system of a heat confluence bus pipe with gas medium as the heat source, which can be used in the occasion where multiple parallel heat sources are merged into a set of waste heat recovery and utilization device through the heat confluence main pipe, and can be jointly supplied with heat energy by multiple parallel heat sources at the same time Or only part of the heat source provides heat energy, which belongs to the technical field of waste heat recovery and utilization devices. Background technique [0002] Usually, the heat source of the waste heat recovery and utilization device whose heat source is gas medium is a one-to-one unit unit, that is, one hot air source is directly connected to one waste heat recovery and utilization device through the conveying pipeline, and there are multiple nearby hot air source sources and front generated hot air sources. In the case where the equipment...

Problems solved by technology

[0002] Usually, the heat source of the waste heat recovery and utilization device whose heat source is gas medium is a one-to-one unit unit, that is, one hot air source is directly connected to one waste heat recovery and utilization device through the conveying pipeline, and there are multiple nearby hot air source sources and front generated hot air sources. In the case where the equipment has mutual backup, the one-to-one arrangement not only requires enough space, but also has poor mutual backup when the equipment that generates the heat source and the waste heat recovery device are deactivated alternately; in the case of a small-capacity heat source, the waste heat Recovery is not easy to realize, and the heat loss of multiple small-capacity waste heat recovery and utilization devices is generally greater than that of a single waste heat recovery and utilization device, the waste heat recovery rate is relatively low, and the recycling economy is poor; in addition, the operation and maintenance workload of multiple waste heat recovery and utilization devices Large and many spare parts
