Description
Technical field
The present invention relates to environmental protection and technical field of industrial equipment, the SO in specially a kind of removing flue gas3Equipment and its technique.
Background technology
Because China progressively accelerates economic development, the demand of crude oil is growing on and on.Domestic crude oil has been not enough to provide national application, so imported crude oil is just continually input into China.In imported crude oil：Iraq, Iran belongs to high-sulfur or sour crude oil.And Mexico's crude oil sulfur content is 3.6%～5.3%.Venezuelan crude (oil) sulfur content is up to 5.5%.As increasing sour crude oil enters Chinese market, at present SOx gradually rises in country's FCCU flue gases, and blue smoke phenomenon occur in increasing FCCU devices.
The content of the invention
The present invention is aiming at the problems referred to above, there is provided the SO in a kind of removing flue gas3Equipment and its technique, the SO in flue gas can be removed3(the SO in flue gas3With powdered reagent reaction, corresponding salt is generated), so as to substantially reduce SO3The discharge of toxic gas, it is very environmentally friendly.
To realize the above-mentioned purpose of the present invention, the present invention is adopted the following technical scheme that, the SO in the removing flue gas of the present invention3Equipment, it is characterised in that：It includes smoke inlet pipe, dry powder enters the mouth of pipe, blower fan, dry powder storage tank, dry powder transfer tube, dry powder injection point and desulfurization washing tower, one end of the smoke inlet pipe is connected with dry powder injection point, the dry powder injection point is arranged on the surface of desulfurization washing tower bottom, and communicate with inside desulfurization washing tower, one end of the dry powder transfer tube is provided with a dry powder and enters the mouth of pipe, a dry powder storage tank is additionally provided with dry powder transfer tube, a blower fan is additionally provided with the dry powder transfer tube that the dry powder enters between the mouth of pipe and dry powder storage tank, the dry powder transfer tube is connected with smoke inlet pipe and communicates.
A kind of SO using in above-mentioned removing flue gas3Equipment removing flue gas in SO3Technique, it is characterised in that it is comprised the technical steps that：
(1). open blower fan, then persistently dry powder is put into into dry powder to enter in the mouth of pipe, in the presence of blower fan, dry powder is entered in smoke inlet pipe by dry powder transfer tube, dry powder storage tank is opened after dry powder is finished so that dry powder storage tank is entered in smoke inlet pipe in the presence of blower fan.
(2) after .30s, in smoke inlet pipe flue gas is passed through.
(3). flue gas and dry powder are entered into after desulfurization washing tower, are continued to desulfurization washing tower spray water.
Preferably, the dry powder is the mixture of more than three kinds of trona, sodium carbonate, sodium acid carbonate, NaOH and magnesia etc..
The invention has the beneficial effects as follows：The SO in flue gas can be removed3(the SO in flue gas3With powdered reagent reaction, corresponding salt is generated), so as to substantially reduce SO3The discharge of toxic gas, it is very environmentally friendly.
