Abstract

The invention discloses a steam temperature and pressure reducing device which comprises an electric temperature and pressure reducing valve which is provided with a direct stroke electric actuator which is connected to a DCS control cabinet, the DCS control cabinet is connected to a computer, one side of the electric temperature and pressure reducing valve is provided with a steam inlet, a pressure sensor and a temperature sensor are arranged on the steam inlet, the other side of the electric temperature and pressure reducing valve is connected to a steam mixing pipe through a temperature reducer which is provided with a filter, an annular hole plate is arranged in the steam mixing pipe, and the inner side of the steam mixing pipe is provided with a protection pipe. A water inlet in the steam mixing pipe is provided with a nozzle which is provided with a filter, the nozzle is connected to a check valve through a pipeline, a restricting orifice plate is arranged in the pipeline, and the check valve is connected to a direct stroke electric actuator 2 through a pipe. The steam temperature and pressure reducing device has the advantages of simple structure, low manufacturing cost, convenient installation, uniform atomization particles, high precision, no clogging and stable and reliable work, and the costs of investment, operation and maintenance are greatly reduced.

Description

technical field [0001] The invention specifically relates to a steam temperature and pressure reduction device. Background technique [0002] The steam desuperheating device is a kind of equipment commonly used in energy-saving projects. The equipment is composed of two parts: a desuperheating water atomization device and a combined vaporization unit. The atomization nozzles pressure-atomize the desuperheating water and disperse it in the high-temperature steam flow. , The combined vaporization unit further forcibly rotates and shears the atomized desuperheating water, and is vaporized by endothermic heat on the surface of the internal parts of the vaporization unit, which significantly strengthens the vaporization process and achieves the desuperheating of high-temperature steam. The traditional steam desuperheating device has a small adjustable flow range, poor quality, and in some cases, it will block the nozzle and pipe. Contents of the invention [0003] The purpose ...
