Wusheng Chunrui Environmental Pollution Hazard Rectification Plan
Serial number |
Hidden danger site |
Environmental hazards |
Corrective measures |
1 |
Second workshop |
When aluminum alkoxide reacts to cast aluminum tablets, the odor of isopropanol overflows; |
Install the induced air of the reactor into the exhaust gas absorption tower, turn on the induced air, put in the aluminum sheet and seal the manhole cover, and then add isopropanol from the upper tank to avoid the exposure of isopropanol to emit odors, and this operation is included in the operating procedures; |
2 |
Second workshop |
The emptying of the isopropyl alcohol upper tank emits an odor
|
The emptying of the isopropanol upper tank is connected to the isopropanol storage tank, and the isopropanol upper tank is kept airtight; |
3 |
Second workshop |
The isopropyl alcohol storage tank is emptied and emits an odor;
|
Install a condenser at the drain of the isopropanol storage tank to condense and recover the isopropanol discharged from the drain. The condenser is evacuated and connected to the exhaust gas absorption system; |
4 |
Second workshop |
The reduction reactor puts solid AlCl3 into the manhole, and the smell overflows |
Contact the supplier for packaging according to the feeding amount of 5Kg, install a feeding funnel at the feeding port of the reactor, and add induced air to extract the smell; |
5 |
Second workshop |
The aluminum alkoxide reaction produces hydrogen to be evacuated, entraining the smell of isopropanol; |
Install a buffer tank condenser and a hydrogen spray absorption tank, connect the emptying of the aluminum alkoxide reactor to the buffer tank, pass the condenser on the buffer tank to condense isopropanol into liquid recovery, and then enter the lye spray tank for absorption Uncondensed isopropanol entrained by hydrogen to eliminate the odor of isopropanol; |
6 |
Second workshop |
The concentrate dissolving kettle has the smell of hydrochloric acid overflowing from the manhole cover; |
Install a vacuum pipeline on the concentrate dissolving kettle, turn on the vacuum to make the dissolving kettle form a slight negative pressure, and vacuum the hydrochloric acid fumes into the water flushing pump and connect to the exhaust gas absorption system; |
7 |
Second workshop |
The smell of the residual liquid of the membrane module of the membrane dehydration system is strong; |
Connect the outlet of the membrane module to the isopropanol storage tank with a closed pipe to avoid exposure of the discharged isopropanol to produce odor; |
8 |
Fourth workshop |
The vent pipe of the sodium percarbonate high tank overflows with odor; |
Connect the high-position tank to the exhaust gas absorption system to keep the material in a closed state;
|
9 |
Fourth workshop |
There is an odor overflow in the empty pipe of the glacial acetic acid high tank |
Connect the high-position tank to the exhaust gas absorption system to keep the material in a closed state;
|
10 |
Fourth workshop |
When K13 is added with ethyl acetate for extraction and layering, use plastic buckets for transfer, and open operation has a big smell; |
Diaphragm pump pipelines are used directly during extraction and stratification, and materials are kept in a closed state during transfer; |
11 |
Fourth workshop |
Sewage collection in the workshop is collected in trenches, and the sewage is exposed to produce odor; |
There are sewage ditches in the filling plain, sewage collection pipelines are installed, and all the pollution points are connected to the sewage collection pipelines; |
12 |
Fourth workshop |
When the barreled materials are extracted, the barrel mouth emits an odor; |
Build isolation rooms for extracting barreled materials, and add induced air to the exhaust gas absorption system; |
13 |
Production workshop
|
In an open-ended reactor, the material evaporates and emits an odor; |
All reactors that need to be operated with open mouths are equipped with unorganized gas collecting hoods to collect scattered exhaust gas and enter the exhaust gas absorption system; |
14 |
Sewage treatment plant |
The biochemical pool emits peculiar smell; |
Seal the biochemical tank, and then connect the exhaust pipe to the exhaust gas absorption system; |
