Abstract
The utility model relates to a safety valve continuous flushing device for an easily crystallized fluid, and relates to an anti-blocking technology in a melamine unit. The safety vavle continuous flushing device solves problems in the prior art. The safety valve continuous flushing device is formed by connecting a valve, a check valve, a guide deluge valve, a safety valve flushing water pipeline, a flowmeter, a rear pipeline and a quench tower, wherein one end of the safety valve flushing water pipeline is connected with the rear pipeline of a quench cold water regulating valve on the upper part of the quench tower, and the other end of the safety valve flushing water pipeline is connected with a safety valve front pipeline on the top of the quench valve; the valve and the guide deluge valve are arranged at two ends of the safety valve flushing water pipeline respectively; the check valve is arranged at one end of the safety valve flushing water pipeline; the flowmeter is arranged above the guide deluge valve at the other end of the safety valve flushing water pipeline.
Description
Technical field: the utility model relates to anti-clogging technology in melamine plant, especially a kind of easily crystallization fluid safety valve continuous flush device.
Background technology: the quench tower in this melamine plant is import key equipment, operating pressure is 2.5MPa, operating temperature is 160 ℃, inner melamine slip, that in the past system 8.0MPa, the melamine reactor of 380 ℃ are come, for preventing quench tower superpressure, at the top of quench tower, safety valve is installed.Because melamine fusing point is up to 354 ℃, and there is the feature of easy distillation, therefore at quench tower run duration, pipeline is often blocked before this safety valve, does not have the effect of protection equipment.
Summary of the invention: the purpose of this utility model is to provide a kind of easy crystallization fluid safety valve continuous flush device of one of guaranteeing that the front pipeline of safety valve is not blocked, protect device security, it has solved the difficult problem in current technology, the purpose of this utility model is to realize like this, it is to be formed by connecting by valve, check (non-return) valve, showering guilding valve, safety valve flushing water pipeline, flowmeter, rear line, quench tower, safety valve flushing water pipeline one end is connected with the rear line of the cold chilled water (chw) control valve on quench tower top, and its other end is connected with pipeline before quench tower top safety valve; Valve, showering guilding valve have been installed respectively in two ends at safety valve flushing water pipeline; Check (non-return) valve has been installed in one end of safety valve flushing water pipeline; Flowmeter has been installed in the top of the other end showering guilding valve of safety valve flushing water pipeline.
The utility model is from the cold chilled water (chw) control valve rear line on quench tower top, draw a pipeline, receive on the front pipeline of quench tower top safety valve, at quench tower run duration, pipeline before this safety valve of continuous flushing, before guaranteeing safety valve, pipeline, not by melamine Crystallization Plugging, does not additionally increase again the system water yield; Do not affect system material component, guarantee equipment safety operation.
Accompanying drawing explanation: Fig. 1 is a kind of schematic flow sheet of easy crystallization fluid safety valve continuous flush device, in figure 1, valve 2, check (non-return) valve 3, showering guilding valve 4, safety valve flushing water pipeline 5, flowmeter 6, rear line 7, quench tower
The specific embodiment: embodiment 1, the utility model are to be formed by connecting by valve 1, check (non-return) valve 2, showering guilding valve 3, safety valve flushing water pipeline 4, flowmeter 5, rear line 6, quench tower 7, safety valve flushing water pipeline 4 one end are connected with the rear line 6 of the cold chilled water (chw) control valve on quench tower top, and its other end is connected with pipeline before quench tower 7 top safety valves.
Embodiment 2, at the two ends of safety valve flushing water pipeline 4, valve 1, showering guilding valve 3 are installed respectively.
Check (non-return) valve 2 has been installed in one end of embodiment 3, safety valve flushing water pipeline 4; Flowmeter 5 has been installed in the top of the other end showering guilding valve 3 of safety valve flushing water pipeline 4.
