Problems solved by technology

However, steam-powered ships in the prior art all use quantitative steam discharge devices with a single quick-opening function, and the quantitative discharge is designed according to the maximum discharge demand of the device’s rated working condition. However, due to the inability to properly regulate the discharge volume of the power plant when the power plant is in different operating conditions and the motor discharge occurs, and does not consider the appropriateness of closing during the removal process at the end of the discharge, this type of steam discharge device usually causes the system to exceed Discharge, trigger multiple repeated discharges, and large fluctuations in operating parameters, etc., seriously affect the operation safety of ships with steam power devices

Abstract

The invention discloses a multifunctional steam dump control system and a control method. The multifunctional steam dump control system comprises a data acquisition device, a synthetic controller and a steam dump device, wherein the synthetic controller is connected with the data acquisition device, performs computation according to operating parameters and initial operating parameters, and generates a tuning control signal, a dump start signal, a dump operating signal and a dump stop signal; the steam dump device comprises a start and stop element, a start and stop driver, an adjustment element and an adjustment driver, and the start and stop driver drives the start and stop element to act according to the dump start signal and the dump stop signal; and the adjustment driver drives the adjustment element to perform steam dump quantity adjustment according to the tuning control signal and the dump operating signal. The invention can solve the technical problems of excessive dump, repeated dump, drastic fluctuation and the like of a conventional steam dump control system with the single quick-starting function, has the characteristics of complete dump function, technical integration, quick action and accurate control, and can meet the multifunctional accurate dump requirements for quick starting, slow stopping and flow adjusting.

Description

technical field [0001] The invention relates to the technical field of emission equipment, in particular to a multifunctional steam emission control system and control method. Background technique [0002] The steam discharge device is the guarantee of the maneuverability and safety of steam-powered ships. The steam power device discharge control requires timely and fast opening, proper discharge and proper closing, and the requirements are relatively high. However, steam-powered ships in the prior art all use quantitative steam discharge devices with a single quick-opening function, and the quantitative discharge is designed according to the maximum discharge demand of the device’s rated working condition. However, due to the inability to properly regulate the discharge volume of the power plant when the power plant is in different operating conditions and the motor discharge occurs, and does not consider the appropriateness of closing during the removal process at the end ...
