Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the utility model one joins ammonia device automatically, comprises automatically join ammonia switch board 1 and the Scatula and anti-the escaping of ammonia device 2 and ammonia that are connected and detects and warning system 3;
As shown in Figure 2, described ammonia switch board 1 of automatically joining comprises PLC 1-1, the man-machine picture 1-2, the conductivity meter 1-3 that are connected with PLC 1-1, the electrically operated valve 1-4 entering ammonia, the electrically operated valve 1-5 entering demineralized water, gas flowmeter 1-6 and enter ammonia manually-operated gate 1-7;
Automatically join ammonia switch board to be made up of ammonification control system and tank level control system.
Ammonification control system is made up of PLC 1-1, man-machine interface 1-2, conductivity meter 1-3 and the electrically operated valve 1-4 that enters ammonia.Its course of work is: utilize conductivity meter 1-3 to detect ammonia electrical conductivity of water in medicine-chest 2-1, and sending conductivity data to PLC 1-1, PLC 1-1 is according to the reduction formula c=(13.2S of electrical conductivity (S) with ammonia concn c (%)
2+ 62.7S) × 10
-7(%) be converted into the concentration of ammoniacal liquor in medicine-chest, when this concentration is lower than setting value, PLC 1-1 sends the electrically operated valve 1-4 that instruction unpack enters ammonia, fills ammonia equably by filling ammonia gas distribution pipe 2-2 bottom medicine-chest 2-1 to medicine-chest; The electrically operated valve 1-4 into ammonia is closed when arriving setting value.
Tank level control system is made up of PLC 1-1, demineralized water water inlet electrically operated valve 1-4 and teletransmission type magnetic flap level gauge 2-11.Its course of work is: the teletransmission type magnetic flap level gauge 2-11 of medicine-chest 2-1 sends liquid level signal to PLC 1-1, and when liquid level is lower than setting value low spacing, PLC 1-1 sends instruction and opens electrically operated valve 1-5 into demineralized water, fills demineralized water to medicine-chest 2-1; When the height arriving level set value is spacing, PLC 1-1 sends instruction and closes electrically operated valve 1-5 into demineralized water.
Other illustrate: 1. can need the concentration of joining ammoniacal liquor by free setting.Concentration can select below 2.5% electrode constant be 0.1 electrode; Concentration is greater than 2.5%, can select electrode constant be 1 electrode.2. the low spacing and height of medicine-chest is spacing all can free setting, but low spacing can not lower than 0, high spacing must not higher than the maximum range of liquid level gauge.3. gas flowmeter 1-6 monitors that ammonia flow makes it to coordinate with making up a prescription into water.General water inlet and fill ammonia and synchronously carry out or fill ammonia lagging a little.Fill ammonia flow too little, can cause reducing in the concentration short time of ammonia in medicine-chest.Fill ammonia flow too large, the concentration instability (increasing) of ammonia in medicine-chest can be caused.4. system debug complete after except fill ammonia bypass door close except, all manually-operated gates are opened entirely.
As shown in Figure 3, described Scatula and anti-the escaping of ammonia device 2 comprise medicine-chest 2-1, what be arranged on medicine-chest 2-1 inner bottom part fills ammonia gas distribution pipe 2-2, be arranged in medicine-chest 2-1, fill the conductance electrode 2-3 be connected with the conductivity meter 1-3 automatically joined in ammonia switch board 1 above ammonia gas distribution pipe 2-2, be communicated with the moisturizing overflow pipe 2-5 of ammonia scrubber 2-4 and medicine-chest 2-1, the top of described ammonia scrubber 2-4 is connected with filling pipe 2-6 and is communicated with the pipeline 2-7 of extraneous air, pipeline 2-7 is provided with the first gas check valve 2-8, the pipeline being communicated with medicine-chest 2-1 top and ammonia scrubber 2-4 top is provided with the second gas check valve 2-10, described Scatula and anti-the escaping of ammonia device 2 are also provided with the teletransmission type magnetic flap level gauge 2-11 be connected with the PLC 1-1 automatically joined in ammonia switch board 1.
Medicine-chest 2-1 material: stainless steel, titanium or plastics.
Fill ammonia gas distribution pipe 2-2: be arranged on the distribution of medicine-chest bottom even.
Conductance electrode 2-3: select electrode constant according to required concentration of making up a prescription, and electrode is arranged on fills 50 ~ 100mm place above ammonia gas distribution pipe.
Moisturizing overflow pipe 2-5: overflow to medicine-chest from ammonia scrubber.
Ammonia scrubber 2-4: mainly purify the air outside discharge chamber.Operation principle is as follows: when filling demineralized water by filling pipe 2-6 to medicine-chest 2-1, medicine-chest 2-1 liquid level rises, because system is airtight, the gas on liquid level top is compressed, because the second gas check valve 2-10 is in closed condition, gas can only be discharged to the demineralized water of ammonia scrubber 2-4 from top, and the ammonia in air is absorbed by demineralized water, and air is by outside the first gas check valve 2-8 and pipeline 2-7 discharge chamber; When stopping is made up a prescription, and during with joined ammoniacal liquor to unit dosing, liquid level declines gradually, the headroom of medicine-chest 2-1 forms negative pressure, at this moment the first gas check valve 2-8 is in closed condition, and when negative pressure reaches certain value, the second gas check valve 2-10 opens, and air enters medicine-chest 2-1, negative pressure is destroyed, and the second gas check valve 2-10 closes again automatically.
As shown in Figure 4, described ammonia detects and warning system 3 comprises ammonia detector 3-1, the instrument of the sound and light alarm on the spot 3-2, the remote alarms instrument 3-3 and demineralized water Electrically operated gate 3-4 that are connected with ammonia detector 3-1, described demineralized water Electrically operated gate 3-4 is connected with spray equipment 3-5.
Ammonia detector 3-1 detects the ammonia content in room air, and when exceeding setting value, sound and light alarm instrument 3-2 and remote alarms instrument 3-3 can send sound and light alarm and remote alarms on the spot respectively on the spot, and notifies that distant place operator on duty processes; Ammonia detector 3-1 sends instruction unpack demineralized water Electrically operated gate 3-4 sprays to reduce Ammonia in Air concentration to indoor simultaneously; When the ammonia density in air is lower than concentration limit set by ammonia detector 3-1, demineralized water Electrically operated gate 3-4 closes automatically.Meanwhile staff should first close into ammonia manually-operated gate 1-7 between dosing, treats that indoor ammonia density reduces laggard row relax.
