Environment control system and control method for box-packed body of gas turbine

Abstract

The invention discloses an environment control system and control method for a box-packed body of a gas turbine. A heat shielding cover is arranged on the inner surface of a chest drum type middle box section, the left end and the right end of the heat shielding cover are connected with two ends of the chest drum type middle box section in a closed mode to define an airflow cavity, a plurality of air film holes are formed in the inner wall face of the heat shielding cover, a third air inlet pipeline and a fourth air inlet pipeline which communicate with the airflow cavity are symmetrically arranged on the upper surface and the lower surface of the right side end of the chest drum type middle box section, and valves and fans are sequentially arranged on the third air inlet pipeline and the fourth air inlet pipeline from outside to inside; and a second air inlet pipeline is connected to the side of a first air inlet pipeline in a penetrating mode, and a valve, a fan and a heater are sequentially arranged on the second air inlet pipeline from outside to inside. According to the control system, the use mode can be adjusted according to different working conditions, and the internal temperature of the box-packed body and the surface temperature of the gas turbine are promoted to rapidly return to the optimal data environment state; and due to the design of the air film holes, backflow of an outlet of an ejector and the self-locking condition of airflow in the box-packed body can be restrained.

Description

Technical field [0001] The present invention belongs to the field of gas turbine technology vessels, in particular, relates to a gas turbine cartons vivo environment control system and control method. Background technique [0002] Currently, many countries are the main research direction of advanced gas turbine as the ship's power plant, using gas turbines are often given priority as the main power plant in the construction of medium and large surface ships. [0003] In the design ship, the ship has means for the gas turbine high technical requirements, in order to facilitate assembly and disassembly, replacement and maintenance, the gas turbine body design generally use cartons, crates itself should have the effect of heat, sound and vibration isolation, at the same time, because the gas turbines are installed in the cabin of the ship, boxed body design will have a tremendous impact on the cabin environment, because the gas turbine operation in closed cartons in vivo; its design...

Problems solved by technology

[0006] In addition, since the structure of the box body is similar to a cube, when the gas turbine is running, there will inevitably be backflow and self-locking phenomena in the space of the box body and at the exit of the ejector, resulting in a decrease in the ejection rate and a decrease in the surface of the box body. There are localized high temperatures on the structure and the surface of the gas turbine, which is extremely detrimental to the performance of the gas turbine
