Description
Technical Field
The invention belongs to the technical field of energy conservation of hot water or steam heat tracing systems, and relates to a heat tracing pipeline synergistic installation device.
Background
The pipeline conveying system is widely used in various production lines in the industrial field and becomes the most important component of various process production lines. With the development of industrial technology and the appearance of more special physical media, the pipeline conveying system puts more strict control requirements on the operating temperature of the pipeline. In order to ensure the safety and stability of pipeline transportation, the method of performing on-way temperature compensation on the main pipeline becomes a main solution for pipeline operation temperature control. The main advantage of pipeline heat tracing is that the pipeline heat tracing is independent of the main system, can be adjusted at will according to the path of the main system, and exerts the flexibility of the pipeline transportation mode to the maximum extent.
The heat source carrier of the heat tracing can be different according to the temperature requirement of the conveying pipeline. The method mainly comprises hot water heat tracing, steam heat tracing and electric heat tracing. The electric heat tracing system mainly adopts a heat tracing cable which is laid outside a pipeline needing heat tracing in parallel or in a winding way, and carries out temperature compensation on a main pipeline by utilizing the electric heat effect. The heat tracing cable is convenient to install and maintain, and the adjustment of the heat tracing temperature can be realized after the heat tracing cable is matched with the temperature controller. In the area where precise temperature control is needed or the equipment has an irregular shape, in order to ensure the heat tracing effect, an electric heat tracing scheme is mostly adopted. In addition, the electric tracing system is also used in the area far away from the steam gas source or the hot water source, so that the electric tracing system has great advantages. However, in some situations with large heat tracing heat demand, the cost of the electric heat tracing system is greatly increased, and the electric energy belongs to high-quality energy in an industrial system, which is not beneficial to energy saving and consumption reduction of the system.
The hot water heat tracing or steam heat tracing scheme is that heat tracing pipes and a main pipeline are laid in parallel along the way, and high-temperature water or steam in the heat tracing pipes is utilized to release heat to the outside to compensate the temperature of the main pipeline. The heat tracing device has the advantage of being capable of providing larger heat tracing power and is particularly suitable for heat tracing of long-distance pipeline systems. In addition, the hot water or steam tracing fully utilizes low-quality heat sources in the industrial system, even waste heat, and greatly improves the comprehensive energy utilization efficiency of the system.
The heat tracing pipeline is used as an important component in a hot water or steam heat tracing system, and the installation standard degree of the heat tracing pipeline directly influences the final heat tracing effect and the operation efficiency. The heat tracing system with heat tracing pipe as heat source has temperature compensating mode for the main pipe, and has mainly convection and radiation heat exchange via the air layer around the pipe and small heat exchange amount. In the installation process of the conventional heat tracing pipeline, much attention is paid to monitoring the distance between the heat tracing pipe and the main pipeline, and the fixation of the relative position between the heat tracing pipes and the establishment and formation of a cavity of an air layer around the main pipeline are neglected, so that the final heat tracing effect is not ideal. At this time, people often adopt a mode of increasing the flow of hot water and steam or increasing the temperature to strengthen the heat tracing, which can solve the problem but reduce the heat efficiency of the heat tracing system. The reason is that the long-distance heat tracing pipe is difficult to fix and needs to be fastened to an external heat insulation layer in the process of installing the heat tracing pipe, so that the space around the main pipe is compressed to a great extent. Therefore, how to ensure the effective establishment of the air layer cavity around the main pipeline and the reasonable distribution of the heat tracing pipes in the cavity becomes the key for improving the heat tracing effect and the operation efficiency of the heat tracing pipe system.
