Description
Technical field
The utility model relates to one and automatically unloads ammonia system, particularly relates to garbage incinerating power plant, mediumand smallscale industrial boilers employing ammoniacal liquor unloads ammonia device as the washing safety automation in the SNCR system of deoxidation compound.
Background technology
Ammoniacal liquor unloads ammonia device and generally adopts single pump or double pump to carry out unloading ammonia, specifically unload ammonia flow process as follows: what ammoniacal liquor was transported to ammonia tank scene by ammoniacal liquor tank car unloads near ammonia pump, by car top hose, connect discharge opening of tank truck and pump intake pipeline, open valve and pump intake valve on tank car respectively, then start pump, start to annotate.But because pump intake pipeline can exist gas, when just starting to annotate, easily there is cavitation in pump, can cause damage to pump.Generally unloading the ammonia filling time is designed to 1 ~ 2 hour, after completing filling, closes the valve at pump and flexible pipe two ends, connecting hose now between tank car and pump can remain more ammoniacal liquor, and for ammoniacal liquor in flexible pipe, general processing mode is that scene is toppled over, easily pollute, and there is certain risk.Simultaneously because filling operating personal cannot pay close attention to pump filling situation in real time, being easy to cause pump suction gas when being near completion filling, causing cavitation erosion, affect pump service life.Unload after ammonia flow process completes whole, unloading in ammonia pump and pipeline is all be full of ammoniacal liquor state, has certain potential safety hazard for a long time.And to unload ammonia equipment or valve overhaul time, slightly do not note just easily causing safety misadventure.20-25% ammoniacal liquor has the characteristic such as intense stimulus and certain corrosive property, also can cause larger harm to human body, can not simply just ignore its potential safety hazard existed because of unloading ammonia system.
Summary of the invention
The purpose of the present utility model overcomes the deficiencies in the prior art, provides a kind of and have safety, clean automatically unloads ammonia device.
The present utility model is achieved through the following technical solutions:
A kind of washing safety automation unloads ammonia device, comprise ammoniacal liquor connecting hose, fast joint, electromagnetic valve, exhaust-valve, floating-ball level switch, buffer tank, foul valve, unload ammonia pump and tank used for storing ammonia, ammoniacal liquor connecting hose is for connecting tank car and unloading ammonia device, fast joint is arranged on the inlet duct of buffer tank top, in order to be connected with tank car flexible pipe, buffer tank outlet at bottom pipeline with unload ammonia pump and be connected, buffer tank is equipped with floating ball lever meter, it is characterized in that: the ammoniacal liquor connecting hose of described connection tank car is connected with buffer tank, ammoniacal liquor in tank car is first crossed buffer tank and is unloaded ammonia enter tank used for storing ammonia by unloading ammonia pump again, the ammonia process of unloading of unloading ammonia device is closed cycle, buffer tank top is provided with demineralized water flow in pipes, pipeline is provided with Controlling solenoid valve, unloading in ammonia process, unload ammonia pump internal cause and be full of liquid so there will not be the cavitation of unloading ammonia pump, and the gas in flexible pipe can rest in buffer tank, also can not impact unloading ammonia pump, buffer tank is equipped with floating ball lever meter, and floating ball lever meter carries out Concatenate shut-down operation to unloading ammonia pump, during floating-ball level switch full level alarm, closes 4 demineralized water electromagnetic valves, wholely unloads ammonia work and automatically completes, and does not need manually on duty.
The present utility model has following beneficial effect:
1. adopt a kind of safety, cleaning, automatically unload ammonia device, can avoid unloading ammonia pump and occur cavitation, extend the service life of pump;
2. can solve and unload ammonia and complete ammoniacal liquor residual in rear hose, prevent from toppling on the spot the pollution and accident potential that bring;
3. the ammoniacal liquor unloaded in ammonia pump, tank is replaced with demineralized water, after can preventing temperature from raising, ammoniacal liquor evaporation causes air pressure to raise the danger brought, and when equipment valve overhauls, demineralized water can directly emptying and can not polluting;
4. unload ammonia device upon actuation, follow-uply unload ammonia work and will automatically complete, without the need to manually on duty.
Accompanying drawing explanation
Fig. 1 unloads ammonia device schematic diagram for washing safety automation.
In figure: ammoniacal liquor tank car 1, ammoniacal liquor connecting hose 2, fast joint 3, electromagnetic valve 4, exhaust-valve 5, floating-ball level switch 6, buffer tank 7, foul valve 8, unload ammonia pump 9 and tank used for storing ammonia 10.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, content of the present utility model is described further:
As shown be washing safety automation and unload ammonia device schematic diagram, comprise ammoniacal liquor tank car 1, ammoniacal liquor connecting hose 2, fast joint 3, electromagnetic valve 4, exhaust-valve 5, floating-ball level switch 6, buffer tank 7, foul valve 8, unload ammonia pump 9 and tank used for storing ammonia 10.
Its control step is as follows:
1., before ammoniacal liquor filling first, open electromagnetic valve and demineralized water is filled up buffer tank, and will unload in ammonia pump and be also full of demineralized water;
2. when first time annotates, 1 ammoniacal liquor tank car to unloading near ammonia device, by flexible pipe by tank car with unload ammonia device and be connected, its connection mode is fast joint;
3. the valve opened tank car and unload on ammonia device pipeline, opens and unloads ammonia pump, start to unload ammonia;
4. unloading in ammonia process, because be full of liquid in pump, so there will not be the cavitation of pump, and the gas in flexible pipe can rest in buffer tank, also can not impact pump; Unload in ammonia process, in buffer tank, liquid level is in full fluid level condition all the time, can be monitored by float switch, if unload liquid level in ammonia process to occur irregular variation, can carry out Concatenate shut-down operation to pump;
5. when unloading ammonia and closing to an end, in tank car, ammoniacal liquor has been unloaded, in flexible pipe, the ammoniacal liquor of final residual can enter buffer tank, buffer tank liquid level can reduce gradually afterwards, when liquid level is low to moderate low liquid level point, floating-ball level switch is reported to the police, and is opened by demineralized water electromagnetic valve, demineralized water will enter buffer tank, and continue for some time;
6., after demineralized water electromagnetic valve opens a period of time, unload the pump of ammonia device and pipeline when being substantially full of demineralized water, interlocked control is closed and is unloaded ammonia pump, and keeps demineralized water electromagnetic valve to continue to open;
7. when being full of demineralized water in buffer tank, and during floating-ball level switch full level alarm, close demineralized water electromagnetic valve, wholely unload ammonia work and automatically complete, do not need manually on duty.
