The design principle of Dongying chemical waste gas scrubber
Product description:
PP acid washing tower can effectively remove the hydrogen chloride gas (HCl), hydrogen fluoride (HF), ammonia (NH3), sulfuric acid mist (H2SO4), chromium acid (CrO3), hydrogen cyanide gas (HCN) and alkali (NaOH), hydrogen sulfide and other harmful gases.
PP acid washing tower using gas and liquid contact between the transfer of pollutant gases into the liquid, and then clean the polluted gas and liquid separation, to achieve the purpose of clean air. The exhaust gas through the filling type of acid washing tower by gas-liquid reverse absorption method, i.e. liquid from the tower top down to mist (or droplets) and spray. Exhaust gas from the tower (reverse flow) to achieve the purpose of gas-liquid contact. This process can be used to cool the exhaust gas, to regulate the gas and to remove the particles, and then to be discharged into the atmosphere after the treatment of the fog.
Brief introduction of waste gas washing process:
The basic principle is to use the contact between the gas and the liquid, and the pollutants in the gas transfer to the liquid, and then clean the gas and the contaminated liquid separation to achieve the purpose of clean air.
After the contact of the particulate pollutants in the air stream with the washing liquid, the liquid droplets or liquid films are diffused on the air particles, or the particles are added to the particles so as to achieve the purpose of separation and removal by the action of gravity and inertia force. The gaseous pollutants are transported by the mass transfer such as turbulence, molecular diffusion and chemical reaction into the washing liquid to achieve the purpose of separating from the inlet gas. And can add chemical substances in washing liquid, to absorb gaseous odor control.
The exhaust gas is filled with a washing tower, which is processed by the reverse absorption of the gas and liquid, and the liquid is sprayed down from the top of the tower (downward) in a fog shape (or small water drop). Exhaust gas from the bottom of the tower (reverse flow) to achieve the purpose of gas-liquid contact. This process can reduce the exhaust gas temperature, gas conditioning, and particle removal. And then through the mist treatment (MIST ELIMINATOR) into the atmosphere.
Inspection and maintenance content:
1: remove the surface dust, dirt.
2: spray head, with or without clogging.
3: clean up the tank with no precipitation blockage, and clean up the record, easy to customize the next cleaning time.
4: To observe the Raschig ring surface might be heavier stains, if required to take place in large area water tank with a neutralizing agent to remove surface stains.
5: according to exhaust odor or data to determine whether or not to replace activated carbon, activated carbon can be used in the sun exposure, so that renewable.
6: check whether there are abnormal water pump, loose and plug.
Qingdao San Da environmental production of horizontal spray purification tower, air flow direction and drug spraying direction are crossed, with compact structure, greatly reduces the height of the system, the single volume reached 500 cubic meters per minute or more. This kind of washing tower filler made of PP material, shape of multi tooth shape of TELLERTTE, void ratio reached 95%, the specific surface area of 90 square meters per cubic metre; in addition to water filling made of PP material, TELLERTTE shape is circular shape, void ratio reached 95%, the specific surface area of 180 square meters per cubic metre. Sprinkler head with PP120 degree rotation without clogging nozzle. There are no metal components in the system. To this end, the whole system has a high acid and alkali resistance; resistance to the whole system is less than 40mmAq, greatly saving energy consumption. The spray purification tower can make two layers of washing and processing of different pollution factors with different agents.
