Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an exhaust gas treatment system for reducing white smoke,

The present invention relates to a treatment system for exhaust gas capable of reducing white smoke.

As a whole, coal-fired thermal power plants are being operated as coal or oil fuel, and as regulations on environmental pollution are strengthened, the spread of complex power plants with high energy use efficiency in power generation systems has increased rapidly, Which is expected to accelerate further. In addition, incinerator combustion facilities using waste incinerators and the operation of many industrial boilers are expanding.

In addition to the development of technologies for the recovery and utilization of waste heat, water and carbon dioxide contained in combustion gases of such combustion facilities, various techniques for removing white smoke due to steam generated during combustion have been developed.

Generally, the flue gas of the combined cycle power plant contains 6-16% of water, and white flue is generated when the flue gas is discharged to the chimney, and the white smoke is increased in the winter when the ambient temperature is low. These white flakes are relatively harmless to human body but cause visual pollution, and it is necessary to remove them because it causes freezing of surrounding roads and cold weather in crops in winter.

A number of techniques (Korean Patent No. 1,126,022) have been developed to remove the white smoke, but it is difficult to install it because of the high cost.

In order to effectively remove white smoke, the combustion gas temperature should be lowered to below the dew point temperature. However, since the combustion gas whose temperature has been lowered can not be discharged by itself, it is forced to be discharged by the blower. In other words, it is inevitable to spend a lot of money because it requires additional energy.

In addition, techniques using ultrasonic waves or plasma are mainly focused on removing mist (dust). This technology has a problem in that, when the dust is sufficiently removed, the moisture content is large, the white smoke reacts with the dust in the air when it is discharged into the air.

An object of the present invention is to provide an exhaust gas treatment system capable of reducing white smoke (a phenomenon in which water vapor appears as white smoke) generated by fine dust, acidic substances and water vapor in a droplet state.

According to an aspect of the present invention, there is provided a combustor comprising: a combustor for generating a high-temperature combustion gas; An SCR / SDR facility for treating the acid gas in the combustion gas discharged from the combustor; A cyclone for removing coarse dust in the combustion gas discharged from the SCR / SDR equipment; An agglomeration tank for agitating fine dust which can not be removed by the cyclone in the combustion gas discharged from the cyclone; A ceramic filter for removing coarse dust in a combustion gas discharged from the flocculation tank; A heat exchanger for recovering waste heat of the oxidized combustion gas discharged from the ceramic filter; An air preheater for secondarily recovering heat from the combustion gas discharged from the heat exchanger; An electrostatic precipitator for removing fine dust in the combustion gas discharged from the air preheater; And a silica gel column for removing moisture in the combustion gas discharged from the electrostatic precipitator.

A heat exchanger for condensing moisture in the combustion gas discharged from the electrostatic precipitator; Reheating to increase the amount of saturated steam in the combustion gas discharged from the heat exchanger; And a silica gel column for further removing moisture of the combustion gas discharged from the reheating heat exchanger.

The flocculation tank may bring the flue gas discharged from the cyclone into contact with the aminosilane compound to aggregate fine dust in the flue gas.

The aminosilane-based compound is preferably a mixture of dimethylsilyldimethylamine, N, N-dimethyltrimethylsilylamine, hexamethyldisilazane, N, O-bis (trimethylsilyl) trifluoroacetamide, and bis (dimethylamino) Lt; / RTI >

The ceramic filter may be made of a material having heat resistance of 500 ° C or more.

The exhaust gas treatment system according to the present invention has an advantage of reducing white smoke generated by fine dust, acidic substances, and water vapor in a droplet state.

Further, the exhaust gas treatment system according to the present invention reduces the occurrence of fouling of the heat exchanger and the like due to fine dust in the combustion gas, suppresses deterioration of the performance of the heat exchanger, and performs stable operation for a long period of time without sacrificing production speed There is an advantage to be able to.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 shows a schematic diagram of a system for the treatment of exhaust gases according to the invention. Fig.
FIG. 2 is a graph showing the amount of dust discharged from the combustion gas discharged from the silica gel column and the combustion gas discharged from the conventional process when the exhaust gas treatment system according to the present invention is operated according to the present invention.
FIG. 3 is a graph showing the moisture content of the combustion gas discharged from the conventional process and the combustion gas discharged from the silica gel column when the exhaust gas treatment system according to the present invention is operated according to the present invention.

The exhaust gas treatment system according to the present invention improves the removal efficiency of fine dust, acidic substances and moisture in the combustion gas, thereby reducing the occurrence of white smoke. Specifically, the fine particles are coarsely filtered and removed by condensation, the acidic substance is removed by the SCR / SDR equipment, and the water is removed by the silica gel column.

Further, since the load of the heat exchanger or the like generated by the conventional fine dust is reduced, the performance deterioration of the heat exchanger is suppressed and the production efficiency is improved.

The combustor 10 is a device for performing a reaction in which a substance binds to oxygen, and may be specifically included in a power generation facility, a boiler, an incinerator, and the like. The combustion gas discharged from the combustor generally contains pollutants such as NO x , SO x, CO, and VOCs.

The SCR reactor has a built-in, and a catalyst layer for reducing the NO X in the combustion gas to a selective catalytic reduction system, the NO X by reaction with a reducing agent is reduced to nitrogen over the catalyst layer.

In addition, foreign matter adhered to the catalyst layer during the reaction can be removed by spraying air through the spray nozzle.

The SDR facility sprayes slaked lime (Ca (OH) 2 ) slurry in the form of fine particles having a diameter of several tens to several hundreds of micrometers through a nozzle provided in a semitransparent reaction column to remove contaminants contained in the exhaust gas from the slurry Absorption, drying and adsorption phenomenon.

The reaction tower removes the dry product generated by the reaction of the slaked slurry with the harmful substances and the dust contained in the exhaust gas.

The cyclone 30 removes coarse dust (particulate matter) from the combustion gas discharged from the SCR / SDR facility.

The cyclone is generally used in the art and is not particularly limited. However, it is preferable that the inside is divided into upper and lower chambers by a lateral wall. Specifically, in the lower chamber, a plurality of centrifugal separators are connected to each other in such a manner that an inlet for introducing the combustion gas is formed immediately below the horizontal wall and the inlet is connected in the tangential direction of the inner peripheral surface. An induction pipe is formed downward and an outlet port through which the combustion gas flows out is formed on one side of the upper side of the upper side of the side wall. The lower part of the cyclone has a shape in which the inside becomes narrower toward the lower end so that coarse dust (particulate matter) can be easily collected and discharged, and a discharge valve for discharging pollutants discharged from the centrifugal separator is provided at the lower end.

The flocculation tank (40) condenses fine dust that has not been removed by the cyclone in the combustion gas discharged from the cyclone.

The flocculation tank brings the flue gas discharged from the cyclone into contact with the aminosilane-based compound. The aminosilane compound performs a chemical adsorption reaction on the surface of the fine dust contained in the combustion gas, and coarsely fines the fine dust into particles having a diameter enough to be removed by a blocking device such as a filter.

Specifically, a chemical adsorption reaction occurs with the aminosilane compound on the surface of the fine dust, and the fine dust on the surface of which the aminosilane compound chemically adsorbs coalesces with each other, and the fine dust is coarsened. The coarsely grained particles can be removed by a ceramic filter, which will be described below, with the diameter of 0.3 m or more, preferably 0.5 m or more.

The aminosilane-based compound is preferably a mixture of dimethylsilyldimethylamine, N, N-dimethyltrimethylsilylamine, hexamethyldisilazane, N, O-bis (trimethylsilyl) trifluoroacetamide and bis (dimethylamino) Lt; / RTI >

Among them, hexamethyldisilazane or bis (dimethylamino) dimethylsilane is preferable in view of price competitiveness and chemical stability at high temperature. More preferred is hexamethyldisilazane.

The hexamethyldisilazane is stable at a high temperature and is 5 times cheaper than other aminosilane compounds, which is advantageous in that it can be easily used in an actual process.

Such an aminosilane compound may be injected by a method commonly used in the art, and specifically, it may be injected by using a device such as a bubble liquid atomizer, an impinger, or the like.

The ceramic filter 50 removes coarse dust in the combustion gas discharged from the coagulation bath. At this time, the size of the fine particles removed by the ceramic filter is 0.3 mu m or more.

The ceramic filter is generally used in the art and is not particularly limited. The ceramic filter is a material having heat resistance of 500 DEG C or higher, and specifically, at least one selected from the group consisting of mullite, SiC, zirconia and cordierite can be used.

The heat exchanger includes a housing having an inner space and a heat exchanger tube repeatedly refracted at a predetermined interval in the housing.

The housing having the internal space is provided with an inlet through which air or water flows for the fuel tube from the heat exchange tube and an outlet through which air or water is discharged and a heat exchange tube for circulating the high temperature combustion gas introduced from the ceramic filter do. Air or water is introduced into the housing to heat the air or water by the heat emitted from the heat exchange tube in which the high-temperature combustion gas is circulated, and the heated hot air, hot water, steam or the like is heated.

The air preheater 70 secondary heat-exchanges the combustion gas discharged from the heat exchanger with air to recover heat. The air preheated through heat exchange is used for combustion air injection of the combustor. At this time, the temperature of the combustion gas discharged from the air preheater is about 140 to 150 ° C.

The electrostatic precipitator 80 utilizes the polarity of electricity to supply a high voltage to separate the dust contained in the air. The present invention removes fine dust and the like finally remaining in the combustion gas discharged from the air preheater.

Such an electrostatic precipitator is generally used in the art and is not particularly limited. For example, a suction port for sucking mixed air including dust is fixed to one side of the housing, and a suction port for sucking mixed air is fixed to one side of the housing. The other side of the suction port, which is the other side of the housing, And a discharge port through which the clean air having collected dust is discharged is formed. In addition, a plurality of dust collecting poles are provided in the space in the housing so as to have a (+) polarity when the power is supplied with a length along the moving direction of the air, and between the dust collecting poles, And a plurality of discharge electrodes in the form of a wire having a negative polarity when supplied with power, may be used.

At this time, the size of fine dust removed by the electrostatic precipitator is 0.3 mu m or less.
