摘要:
The present invention relates to a machine for heat exchange with a product, comprising: a tubular recipient (1) internally housing the product, where the tubular recipient (1) comprises a cross-section comprising a U-shaped geometry; at least one thermal device for heating or cooling the product, where said at least one thermal element comprises an inflow duct (2) and an outflow duct (3) for a heat transfer fluid; and at least one scraper blade inside the tubular recipient (1) and configured for entraining the product inside said tubular recipient (1); which allows accelerating the product heating or cooling time as a result of a great improvement in the heat transfer; as well as simplifying the design of the components forming part the machine object of the invention.

This invention provides a method for manufacturing steel mesh reinforced plastic composite pipe, which includes: the transverse steel wires (11) are supplied to the steel mesh welding machine from the transverse wire reels hung outside the device, a fuzzy resistance welding technique is adopted to form the steel mesh framework by welding the transverse steel wires onto the longitudinal steel wires (1) coming from the longitudinal wire feeder. The formed steel mesh framework is continuously hauled off and passes through the combining die (9), the combining die embraces the steel mesh framework and receives the molted thermoplastic supplied from the side face of the combining die, the plastic and the steel mesh framework combine inside the combining die to form the semi-finished pipe, which is hauled off (7) through the cooling tank (6) to form the finished composite pipe. This invention also relates to a production line for manufacturing the composite pipe as well as a piping system formed by connecting the pipes with joining structures.
摘要:
The invention is directed to a process to obtain a compressed gas starting from a starting gas having a lower pressure by performing the following steps: (i) increasing the pressure and temperature of a gas having an intermediate pressure by means of indirect heat exchange against a fluid having a higher temperature to obtain a gas high in pressure and temperature, (ii) obtaining part of the gas high in temperature and pressure as the compressed gas, (iii) using another part of the gas high in temperature and pressure as a driving gas to increase the pressure of the starting gas in one or more stages to obtain the gas having an intermediate pressure for use in step (i). The invention is also directed to a configuration wherein the process can be performed and directed to a process to generate energy using the process.
