A device and method for recovering waste heat from perforating equipment in a steel pipe plant

Abstract

The invention discloses a waste heat recycling method and device for perforation equipment in a steel pipe plant. The method includes the steps that a pipe blank is sealed along the perforation flow path by the adoption of a thermal insulation device, and the pipe blank is perforated in a confined space; an air feeder with certain flow is installed at one end of the thermal insulation device, cold air of the outside is fed into the thermal insulation device, the cold air and the pipe blank in perforation are subjected to heat exchange in the confined space, and thus heat of the pipe blank is absorbed; the other end of the thermal insulation device is connected with a conveying pipeline, and hot air at a certain temperature is led out and directly fed into an air supply system of a pipe blank heating furnace to serve as preheating air; and high-temperature flue gas produced by the heating furnace is fed into a waste heat boiler, and steam is generated for other purposes. In this way, perforation waste heat of a steel pipe can be recycled, and certain energy is saved.

Description

technical field [0001] The invention relates to a method and device for recycling waste heat in a steel pipe factory, and is aimed at the method and device for recycling waste heat of a pipe blank during the piercing process of a steel pipe factory. Background technique [0002] Since the reform and opening up, with the improvement of the economic level, the energy consumption has been increasing. The development of my country's economy is very dependent on energy. Although my country's energy storage is large, but the population is large, the per capita share is not as high as that of the world. The average level, and industrial energy consumption is fast and large, but the energy utilization rate in industrial production is far below the level of developed countries, the energy situation is not optimistic. Facing the severe energy situation, our country has put forward the energy policy of saving energy and reducing consumption, and promulgated the "Energy Conservation Law ...

AI Technical Summary

Problems solved by technology

The development of the national economy, the modernization of national defense science and technology, and the improvement of people's quality of life will inevitably require an increase in the demand for energy. The supply capacity of products will not increase significantly in the short term, and the development and utilization of new energy will be restricted by factors such as capital and technology. It is impossible to use it on a large scale in the short term, so the gap in energy demand can only be made up by energy conservation.
