摘要： PURPOSE:To prevent clogging and pressure loss of the air heater, by injecting high speed air flow containing hopper ash of economizer and precipitator into the air heater by means of soot blower, when denitrating the coal combustion waste gas by using NH3 and catalyzer. CONSTITUTION:When NOX in the coal combustion waste gas is removed by using catalyzer, using NH3 as reducing agent, hopper ash from an outlet hopper 8 of an economizer 2 and a first feed hopper 9 of an electric precipitator 3 is injected to an air heater 5 provided in the downstream side of a denitration catalyzer layer 4, by mixing with high speed air flow of soot blowers 6, 7. As a result, unreacted NH3 and reactant of SOX sticking to the element of the air heater 5 may be easily removed. Operation of the soot blowers 6, 7 is needed only once a day or once a week.

摘要： PURPOSE:To use decomposed ammonium for denitration and treated ash water for pollution-free filling in land or raw material for cement by subjecting the ash deposited with ammonium salt to ammonium salt decomposition by wet system then drying the same by hot air. CONSTITUTION:When coal burning exhaust gas or the like is denitrated by using ammonia as a reducing agent, the ash deposited with ammonium salt is captured. About 0.25-0.75 weitht of the weight of ash content, preferably 0.5 weight of water C and coal of about 1-1.2 mole equivalent of ammonium salt and sulfuric acid anhydride deposited to ash are added to this ash. These are thoroughly mixed with a mixer 5 to substitute the sulfuric acid components of the ammonium salt or sulfuric acid anhydride to gypsum, after which the mixture is dried by hot air with a drying machine 6. Then, ash content D and ammonia gas may be recovered. The ammonia gas is returned to a denitration unit 2 and the ash content D is discarded or utilized as filling in land and for raw material for cement.

摘要： PURPOSE: To remove phosphates in waste liquid effectively and to contrive to save resources and to reutilize wastes by bringing solid wastes contg. a large amt. of Ca and F compds. contained in the waste water of stack gas desulphurization process into contact with the water to be treated.
CONSTITUTION: The water to be treated 1 is mixed and brought into contact with powdery sludge 3 and recycled seed crystals 7 in a crystallization reaction vessel 2. In this stage, the phosphates contained in the water to be treated deposit on the surface of the powdery sludge 3 and the recycled seed crystals 7 in the form of crystals of calcium phosphate. At the start of the operation, the powdery sludge is charged in a proportion to obtain 5W10g/l liq. mixture, but the amt. of the charge is set in the stationary state of the operation to obtain a weight ratio of Ca contained in said powdery sludge to the phosphate contained in the water to be treated to be 1:(3W5). The liquid mixture in the crystallization reaction vessel 2 is transferred to a precipitation vessel 5 where it is separated into water to be treated 6 and seed crystal 7 to be recycled.

摘要： PURPOSE: Phosphates contained in liquid are effectively removed by bringing particulate material contg. an insoluble Ca salt into contact previously with the water to be treated, then allowing further the particulate material to contact with the water to be treated in the presence of Ca salt and be separated.
CONSTITUTION: Phosphate-contg. water to be treated is introduced into a crystallization reaction vessel 3 while mixing with a Ca salt 2 contg. ≥ equiv. amt. of Ca. The pH of the water to be treated is adjusted to 6W8 in the crystallization reaction vessel, and the crystallization reaction proceeds by the mixing and contact of seed crystals 10 for the preliminary contact, water to be treated 1, and Ca salt 2. The liquid mixture is separated in the succeeding solid-liquid separating vessel 4 to supernatant water 5 and precipitated seed crystals 6. Most of the seed crystals 6a among the precipitated seed crystals 6 are returned continuously to the crystallization reaction vessel 3, and a part of the seed crystals are discharged as excessive seed crystal 7 out of the system intermittently or introduced continuously into a regeneration vessel as seed crystals for regeneration 6b.

摘要： PURPOSE: To prevent the clogging and the corrosion of a dust collection apparatus, by a method wherein a gas is sent into the dust collecting apparatus while the temp. and the moisture of the gas are regulated during a period for introducing the gas into the dust collecting apparatus and air from the outside of a furnace heated by a heat accumulator is introduced into the dust collecting apparatus during a period not introducing the gas into said dust collecting apparatus to constantly adjust the temp. in the dust collecting apparatus.
CONSTITUTION: A dust-containing gas from an oxygen steel manufacturing furnace 1 is mainly introduced into a heat recovery device 6 and the part thereof is introduced into a heat accumulator 7 to be heated by the heat accumulating part 7b thereof. These gases are further guided to an evaporative cooling tower 10 to lower the temp. thereof to a set temp. while simultaneously humidified and soda ash and other dusts in the exhaust gas are recovered by a dry dust collecting apparatus 3. When the generation of a high temp. gas in the oxygen steel manufacturing furnace 1 is stopped, in order to prevent the lowering in the temp. of the dry dust collecting apparatus 3, an auxiliary blower 4b is operated to guide air in the vicinity of the furnace 1 to the heat accumulating part 7b and heated to a high temp. to be introduced into the dust collecting apparatus 3.
