Ground torch grading emission control device and method

Abstract

The invention discloses a ground torch grading emission control device and method. The ground torch grading emission control device comprises an empty main pipe, a grading emission system, a grading control system, a burner and a ground torch combustion furnace, wherein one end of the grading emission system communicates with a main pipeline, the other end of the grading emission system communicates with the burner, the grading control system communicates with the grading emission system and the main pipeline, and the burner is arranged in the ground torch combustion furnace. According to theground torch grading emission control device, the mutual effect of all levels of emission systems can be avoided, smokeless combustion can be realized under the pressure, automatic switching can be realized when any level fails, and the safety is high.

Description

technical field [0001] The invention belongs to the field of combustible gas discharge in petrochemical enterprises, and in particular relates to a ground flare staged discharge control device. Background technique [0002] The combustible gas treatment device is an indispensable safety emission combustion facility for the relevant production devices of petrochemical enterprises. Timely, safe and reliable emission and combustion; complete combustion, low noise, meeting environmental protection requirements; low operating costs, small protection radius, are the most basic requirements for the flare gas treatment device. The ground torch has the characteristics of small heat radiation, convenient maintenance, light pollution to the surrounding environment, small footprint, and can realize smokeless combustion. Like the elevated torch, the ground torch system is a new type of smokeless, low-noise and environmentally friendly torch Gas treatment devices are gradually being used...

Problems solved by technology

Option 1 is easy to operate, but there are risks of inaccurate pressure values ​​at the pressure measurement points, false reports of pressure gauges, and failures, resulting in system pressure and failure to discharge in time; Option 2 has pressure loss due to the pressure loss of the graded regulating valve or switch valve itself and the branch venting pipeline , during the opening or closing process of the valve, the pressure value at the pressure measuring point will fluctuate frequently, making the control valve unable to perform stable control, resulting in unstable combustion of the torch, and easy to cause unfavorable working conditions such as noise, vibration, and incomplete combustion of the torch , for the low-pressure system, when the difference between the setting values ​​of all levels is small, it is easy to cause the system to hold pressure and the possibility of not discharging in time

During the use of the above two schemes, it was found that there was system pressure suppression and cross-stage discharge, the use effect was not ideal, it was not conducive to safe production, and it was not convenient for daily operation and maintenance.
