Heating device for temperature increment and pressure increment of long-distance delivery thermal pipe and using method of heating device

Abstract

The invention discloses a heating device for temperature increment and pressure increment of a long-distance delivery thermal pipe. The heating device for temperature increment and pressure increment of the long-distance delivery thermal pipe comprises a solar collector, a storage battery, heating pipe sleeves, a control box, a temperature-pressure sensor and wires, wherein the heating sleeves are evenly distributed and arranged on the thermal pipe in the length direction, and the heating pipe sleeves on the thermal pipe are spaced from one another by the distance of 30-60 meters; the heating pipe sleeves are each in a circular ring shape, and the heating pipe sleeves are connected with the additionally-arranged storage battery through one wire; the solar collector is arranged on the other side of the storage battery, and the storage battery and the solar collector are connected through one wire; the temperature-pressure sensor is arranged on the thermal pipe and correspondingly connected with the control box through one wire; and the control box is connected with the storage battery through one wire. The heating device for temperature increment and pressure increment of the long-distance delivery thermal pipe has the advantages that the heating devices are distributed in a whole long transportation system discontinuously, and changes of the temperature and pressure in a pipe network can be found in time; and meanwhile, measures can be taken in time to compensate the changing temperature difference, it is ensured that the temperature and pressure in the thermal pipe network are normal, and production and living requirements are met.

Description

technical field [0001] The invention relates to an auxiliary device on a long-distance large-diameter transport heat pipe and a method for using it, more specifically, to a heating device for raising the temperature and pressure of a heat pipe for long-distance transport and a method for using it. Background technique [0002] At present, in the operation of thermal pipelines with a long distance of more than 1000 meters and a large diameter of more than 0.5 meters, after the thermal pipeline has been in operation for a period of time, the temperature and pressure of the steam and water running in the thermal pipeline will drop, resulting in when reaching the user, The thermal indicators of the required steam and hot water cannot meet the requirements, which will affect production and life. Due to the occurrence of the above situation, the development of long-distance heat transmission pipelines in my country is seriously restricted. Contents of the invention [0003] The p...
