Zhejiang waste gas administers equipment to teach everybody the way of equipment of waste gas processing

We are limited company of equipment of environmental protection of rich of grand of Zhejiang of manufacturer of equipment of processing of Zhejiang waste gas, we serve as case with batteries of Xining smooth hot season and package project today, say to administer the administers waste gas respect problem of equipment about waste gas for, everybody is discussed jointly, the place that has a mistake still asks each colleague to point out, correct jointly, thank!

Above all, project introduction:

Batteries of Xining smooth hot season and package project are located in Xining (national level) town of city of area of garden of industry of Dong Chuan of economic technology development, Xining east Dong Ludong of side, Kunlun carries village of bay of area poplar channel on the west to. After put into production of this project first phase project, achieve solar battery of year of crop 200 MW piece with 200MW component ability.

2, exhaust emission chroma reachs the capacity that use acid

Cell product line makes working procedure of cloth with soft nap, quarter corrode use nitric acid and hydrofluoric acid to polycrystalline silicon piece undertake pickling, purify surface impurity, acerbity mist of mist of many nitric acid and hydrogenous Buddha is contained in the waste gas that discharges wind, waste gas volatilizes show erupt quality, especially NOx, concentration is very high, average concentration is 1000-2000mg/m3, instantaneous chroma can amount to 6000mg/m3, at present line of cell of Xining much brilliant uses up nitric acid everyday (chroma 65%)2500L, hydrofluoric acid (chroma 49%)2000L, because use acerbity amount big, the waste gas gross of generation is very big also.

3, the means that at present waste gas administers

Waste gas administers equipment to administer the means method of waste gas

This project uses one level at present wet purify means, from workshop craft paragraph the soda acid waste gas that take out enters acid below the action of centrifugal fan / alkaline mist purifies a tower, in acid / alkaline mist purifies tower interior, counteract fluid classics to gush drenchs the system sprays and fall, with the acid in waste gas / alkalescent gas happens counteract reaction to rise to purify the effect thereby.

Basically have the following facility:

Remarks of amount of serial number name

A sheet covers purifier of waste gas of 1 acerbity mist M3/h of processing wind force: 27000

A sheet covers purifier of waste gas of 2 acerbity mist M3/h of processing wind force: 20000

2 sheet cover purifier of waste gas of 3 acerbity mist M3/h of processing wind force: 16000

Every equipment basically is included add explosion proof of medical system, water pump, stainless steel washer, automatically anticorrosive fan / chimney of wind of canal of wind of anticorrosive fan, glass reinforced plastics, platoon reachs explosion proof of glass reinforced plastics protective steel is worn etc.

4, the current situation after at present waste gas administers:

After the waste gas that passes processing at present entrusts tripartite to detect, in the 240mg/m3 that the result shows to the secondary standard that discharges index to all discharge index GB16297-1996 integratedly in air pollution asks (average concentration of actual measurement NOx is controlled for 170mg/m3) . But clean control cloth with a soft nap or pile on one or either side, wash phosphor to engrave tower of off-gas treatment of corrode working procedure to still appear maize aerosol phenomenon.

3 · waste gas administers the result that the need after transforming achieves

According to the requirement that Xining air pollution administers, exhaust emission chroma should amount to mark not only, and the sense organ also should amount to mark, namely exhaust emission cannot appear risk ” Huang Yan ” phenomenon.

4 · ” Huang Yan ” a few kinds of plan with common processing:

Plan one:

In original one class wet physics increases to do type adsorption to purify processing on the foundation that treats a tower equipment.

In original one class wet physics increases to do type adsorption to purify processing on the foundation that treats a tower equipment. Main material is SDG sorbent, its exterior is cylindrical grain, accumulation proportion is 0.6 — 0.7, can handle aleatoric pH indicator of all kinds mixture acid is angry. This product is opposite especially azotic oxide (NOx) processing is having very distinct effect. Its are right azotic oxide (NOx) initiative and adsorptive rate can achieve 95% above, adsorptive capacity is 10% — 20% , adsorptive efficiency is 70% — 95% , its use temperature to be 50 degrees normally the following, can be able to bear or endure the high temperature of 300 degrees of above, be able to bear or endure wet the vapor that is less than 80 degrees. Ⅰ of a ton of SDG- sorbent but adsorptive NOX250-300kg.
