Abstract
The invention provides an acid gas treatment system and an acid gas treatment method, and aims to thoroughly solve the problem that acid gases leave out from production equipment and production plants into the atmosphere. The acid gas treatment system includes two parts consisting of a software part and a hardware part. The acid containing gases are sent into an acid gas absorption tower by a blower fan, from the bottom to the top, an absorption liquid is sent to the tower top by an acid proof pump, the absorption liquid is evenly sprayed down by a liquid distribution device to form countercurrent absorption, and neutralized gases are defogged by an fog-acid gas-collecting chamber in the tower, and then is discharged into the atmosphere via a smoke pipe. Acid gas treatment work is finished by automatic operation and control of a software program module, a software is an acid gas treatment program module in a central processor, and a pH sensor, an electrically operated valve and a monitoring unit are arranged in a hardware device. Through use of the acid gas treatment system and the acid gas treatment method, damages caused by acid gas inhalation of chemical plant workers and influences on residents and environment around chemical plants can be solved.
Description
Technical field
The present invention relates to chemical field, be specially a kind of acid gas treatment system and method thereof.
Background technology
Acid gas is often discharged in chemical plant, grievous injury workpeople healthy, work under the environment of the acid gas of being everlasting, there will be the headache dizziness and nausea, affect workpeople's work, the resident living around also giving has been brought destruction extremely, and enter atmosphere, destroy whole earth environment, so as modern chemical plant, must process acid gas, although existing technology is also processed acid gas, method is not very good, and automaticity is not high, monitoring, do not process not thorough.
Summary of the invention
The object of the invention is to thoroughly to solve acid gas from production equipment and give birth in factory building the problem that leaks in atmosphere, a custom-designed cover system and method, system comprises software and hardware.
Hardware is apparatus, and software is the acid gas handler module in central processing unit, and PH sensor, motor-driven valve, supervising device are installed in hardware unit, by software program module, is automatically operated and is controlled.
The present invention is by the following technical solutions:
Acid gas processing device comprises: acid gas absorption tower body (1), acid mist collection chamber (2), blower fan (3), plastic pump (4), sensor 1(5), sensor 2(6), sensor 3(7), electrically operated valve 1(8), electrically operated valve 2(9), the acid gas handler module (14) in buck pump (10), potass pool liquid level juice (11), potass pool (12), treatment pond (13), central processing unit.
Two-layer filler is arranged in tower, one deck corrugated plating, two layers of cascade ring, have contacting of larger surface and pneumatosis liquid, abundant mass transfer, efficiency is high.
Use blower fan, with air exhauster in factory building, reactor, fluid bed take out the acid gas that comes, sends the acid gas absorption tower to, process.
The method that acid gas of the present invention is processed is: will contain acid gas with blower fan and send the acid gas absorption tower to, and flow from bottom to top, absorption liquid is sent to tower top by acid-proof pump, spray downwards uniformly by liquid distributor, form counter-current absorption, the gas after neutralization, enter atmosphere through chimney.
Factory building inner air-cleaning degree: the acid gas absorption tower purifies air and can reach 97% and enter atmosphere after neutralization.
Beneficial effect of the present invention is.
1, it is very low that the gas that enters atmosphere contains acid number, meets the discharge standard of national regulation.
2, in factory building, air is constantly updated, and what factory building was interior contains acid number also seldom, on the employee is healthy, can not affect.
3), acid gas is compared and processes thoroughly.
4, automaticity is high, monitoring is rigorous, and every operation and monitoring are undertaken by the program of system.
5, greatly reduce surrounding resident and environmental disruption.
6, because be automatic control operation, during lower than job requirement, apparatus of the present invention can quit work automatically when the acid gas amount, and when the acid gas amount occurred in a large number, apparatus of the present invention can strengthen operating efficiency.
7, can collect quantitative by-produced gypsum.
Description of drawings
Fig. 1 is the schematic diagram of apparatus of the present invention.
The specific embodiment
Below the present invention is described in further detail by reference to the accompanying drawings with embodiment:
Example: take the automatic production line of solid ferric polysulfate as example.
1, the source of acid gas.
1), ferrous sulfate deposits in warehouse,, though be that semitight is deposited, still has certain tart flavour evaporation to cause acid gas with air pollution in factory building.
2), semi-finished product smell in equipment, through the collection chamber of row of conduits to acid gas absorption tower import department.
3), semi-finished product emit tart flavour in the transfer process of the equipment room of automatic assembly line, pollute the air in factory building, by row of conduits to collection chamber.
4), acid storage tank is to the another parts of pipeline, valve of equipment etc., the tart flavour that overflows when maintenance pollutes the air in factory building.
2, method of work of the present invention.
L), adopt two 15000 cubes m/hs acid gas treating columns, be arranged in three (i.e. 10 meters high positions) absorption towers, floor top, control room 15000 cubes of m/hs of exhaust blowers are installed, the exhaust blower import is directly led in factory building, send the acid gas that air exhauster is taken out to the acid gas absorption tower, process.
2) as shown in Figure 1, acid gas absorption device comprises: acid gas absorption tower body (1), acid mist collection chamber (2), blower fan (3), plastic pump (4), sensor 1(5), sensor 2(6), sensor 3(7), electrically operated valve 1(8), electrically operated valve 2(9), the acid gas handler module (14) in buck pump (10), potass pool liquid level juice (11), potass pool (12), treatment pond (13), central processing unit.
3), the method for work in the acid gas absorption tower: advance the gas in tower, take out factory building by air exhauster and include acid gas, from bottom to top, absorption liquid is sent to tower top by acid-proof pump and sprays downwards uniformly by liquid distributor, form counter-current absorption, gas after neutralization after the acid of the demist in tower section, enters atmosphere through chimney.
4), approximately 23000 cubic metres of air volumes in factory, the absorption tower of adopting 15000 cubes of m/hs of air quantity, contain acid gas from bottom to top, 1.5 hours can be with air update all in wide room once.Air enters atmosphere after purifying.
