Definitions
- the present invention relates to an exhaust gas treatment apparatus, and more particularly, to an exhaust gas treatment apparatus of a system for denitrating exhaust gas containing dust by a dry process using ammonia and a catalyst.
- a method for selectively reducing with ammonia using a catalyst As a method for removing nitrogen oxides in exhaust gas, a method of selectively reducing with ammonia using a catalyst has been mainstream, and the apparatus has a denitration activity and a parallel flow path with respect to exhaust gas.
- An apparatus that introduces ammonia as a reducing agent into a reactor filled with a catalyst layer having a denitration reaction to perform a denitration reaction is used.
- the dust When dust is contained in the exhaust gas, such as coal fired power, the dust is usually removed by installing an electrostatic precipitator or bag filter in the downstream of the denitration unit and air preheater, but the electrostatic precipitator is installed in the upstream of the denitration unit. May be installed.
- the cross section of the reactor is made large and the flow rate of gas flowing into the catalyst layer is lowered.
- the dust removal equipment becomes large due to the treatment under the condition of high exhaust gas temperature, and after the dust removal, the wear of the catalyst is remarkably reduced, but the remaining fine dust remains in the catalyst layer. It adheres to and becomes easy to block. For this reason, measures such as enlarging the exhaust gas flow path in the catalyst layer are taken, and the catalyst volume is increased.
- the duct is provided with a vertical portion with respect to the flow of the exhaust gas to suppress the transfer of relatively large dust such as a lump soot. Measures are taken to collect and discharge soot with a hopper installed at the bottom.
- a mesh screen such as a wire mesh is installed in the duct at the outlet of the boiler, and measures are taken to collect dust having a particle size larger than the opening.
- a mesh screen pitch: 5 mm, wire diameter: 1 mm as a reference example
- a louver-like plate is placed in the duct.
- a method is adopted in which a large particle size dust is collided and dropped.
- the flow rate of the exhaust gas in the flue downstream of the boiler economizer is about 15 m / s, there is a concern about deterioration over time due to wear.
- a method has been proposed in which a mesh screen such as a metal mesh is installed perpendicular to the gas flow at the reactor inlet, and dust larger than the catalyst flow path is collected by adjusting the opening of the screen. Since this method does not have a dust removal function, there is a concern that clogging may occur over time.
- Patent Document 2 tends to accumulate large particle size dust on the reactor side of the boiler side, a mesh or a perforated plate for removing dust is installed at the lower part of the upper two vanes. Although it is described that ash is removed, in this case, the gas flow tends not to be uniform.
- the object of the present invention is to solve the above-mentioned problems and to easily reduce dust having a large particle size that affects clogging and wear and prevent it from accumulating in the catalytic reactor.
- the present inventor efficiently removes dust by installing an inclined thin plate slit having a specific structure on the boiler economizer outlet flue or the upper part of the reactor catalyst layer. It came to solve. That is, the invention claimed in the present application is as follows.
- An exhaust gas denitration apparatus equipped with a denitration reactor having a catalyst layer for removing nitrogen oxides in combustion exhaust gas, wherein the exhaust gas flows vertically from a horizontal direction through an exhaust gas duct upstream of the denitration reactor.
- a duct structure having a rising portion that changes in a direction, and a plurality of thin plates are provided in the horizontal duct at the rising portion inlet and / or the catalyst layer inlet in the denitration reactor, and the opening of the catalyst layer
- An inclined thin plate slit arranged in a vertical direction with a slit width smaller than the width and a predetermined inclination angle on the cross section of the exhaust gas flow path, and a dust collecting and discharging portion attached to the lower end of the inclined thin plate slit
- An exhaust gas denitration apparatus characterized by that.
- the opening width of the catalyst layer is 3 to 10 mm
- the height of the inclined thin plate slit is 30 to 100 mm
- the inclination angle is in the range of 5 to 45 degrees
- the thin plate slit installed in the duct or at the catalyst layer entrance is a thin plate, for example, a metal thin plate having a thickness of 3 mm or less and a height of 30 to 100 mm, and a slit width smaller than the opening width of the catalyst layer of 3 to 10 mm. And a plurality of sheets arranged in the vertical direction.
- the shape of the thin plate is an elongated rhombus-shaped object in the embodiments described later, but may be any shape as long as it can be installed in the cross section of the exhaust gas passage.
- the height is selected from a range of 30 to 100 mm in consideration of dust collection efficiency and pressure loss.
- the inclined thin plate slit is formed by arranging the thin plate slit in the cross section of the exhaust gas channel so as to form an angle of 5 to 45 degrees with respect to the horizontal direction.
- the slit width is larger than the opening width of the catalyst layer, the catalyst layer is likely to be clogged with dust, and when the inclination angle of the thin plate slit is less than 5 degrees with respect to the horizontal direction, the dust collecting effect is reduced. If the temperature exceeds the limit, wear of the thin plate due to dust and pressure loss are likely to increase.
- dust having a large particle diameter can be reduced from the exhaust gas introduced into the catalyst reactor, and wear and blockage of the catalyst layer can be suppressed.
- the inclined thin plate slit used in the present invention is more resistant to wear and durable than conventional mesh screens and wire meshes (wire nets), and the structure of the inclined slit makes it possible to move to the lower hopper without being caught in the dust falling direction. Dust can be collected efficiently. Furthermore, it is not necessary to greatly reduce the flow rate of the gas introduced into the catalyst layer, the decrease in the dust conveying force can be suppressed, and the dust accumulation on the catalyst layer can be suppressed. Furthermore, since it has a dust discharge mechanism, the plant can be operated without being influenced by cleaning of collected dust at the time of stopping.
- FIG. The partial schematic diagram of the inclination thin plate slit used for this invention.
- FIG. 1 is an explanatory view of an exhaust gas treatment apparatus showing an embodiment of the present invention
- FIG. 2 is a partial schematic view of an inclined thin plate slit used in the present invention.
- This apparatus is provided in a denitration reactor 2 having a catalyst layer 3 for removing nitrogen oxides in combustion exhaust gas 1 discharged from a boiler or the like, and a horizontal duct 10 upstream of the exhaust gas inlet of the denitration reactor 2. And a rising portion 9 in which the flow of the exhaust gas changes from the horizontal direction to the vertical direction, and in the horizontal duct 9 at the inlet of the rising portion 9 and at the inlet of the catalyst layer 3 in the denitration reactor 2.
- inclined thin plate slits 13A and B in which a large number of thin plate 14 having a rhombus shape are arranged in a vertical direction with a slit width smaller than the opening width of the catalyst layer and at a predetermined inclination angle in the cross section of the exhaust gas flow path Dust collecting and discharging portions 11 and 12 are provided at the lower ends of the inclined thin plate slits 13A and 13B, respectively.
- 4 is a hopper provided in the horizontal duct at the outlet of the economizer 5 and 7 is a screen plate provided at the inlet of the denitration reactor.
- the exhaust gas 1 enters the denitration reactor 2 from the boiler outlet via the horizontal duct, the vertical duct and the horizontal duct, and is treated with the catalyst layer 3, but the inclined thin plate slit 13 is the economizer 5 One is installed in the horizontal duct at the outlet and one is installed in the inlet of the catalyst layer 3 in the reactor.
- dust having a large particle size is collected in the inclined thin plate slits 13A and 13B, and is installed on the dust collecting / discharging part provided at the lower end thereof, that is, on the side of the hopper 11 and the reactor below the rising part duct 9.
- the hopper 12 collects each. As a result, inflow of dust having a large particle diameter into the catalyst layer is reduced, and the clogging of the catalyst layer is reduced.
- two inclined thin plate slits (13A and B) are installed.
- either the horizontal duct at the inlet of the vertical duct 9 or the inlet of the catalyst layer 3 in the reactor is used. Just install it.
