Description
Technical Field
The utility model belongs to the technical field of energy saving and consumption reduction, especially, relate to a cold quick-witted side blast apparatus of comb.
Background
In the cement production process, the clinker contains more fine powder, red river phenomena can occur on two sides of one section of the grate cooler, heat can not be well recovered at one section of the grate cooler easily, the cooling effect is influenced, and the energy consumption is increased; but also can reduce the service cycle of a section of grate plate of the grate cooler, and lead to the rise of material consumption.
Disclosure of Invention
The utility model provides a cold quick-witted side blast apparatus of comb, the device can effectively solve the problem of cold quick-witted one section red river of comb, improves the cold quick-witted cooling effect of comb, extension comb board life cycle.
In order to realize the purpose, the utility model adopts the following technical proposal:
a grate cooler side blowing device comprises: the method comprises the steps that a centrifugal fan is installed at the front end of a grate cooler, an outlet of the centrifugal fan is connected with an air pipe through a flange bolt, the other end of the air pipe is welded on an energy storage pipeline, high-pressure air generated by the centrifugal fan is led to the energy storage pipeline on one section of two sides of the grate cooler, two sections of energy storage pipelines are installed on two sides of the grate cooler respectively to ensure that the pressure entering the interior of the grate cooler is kept constant, the outlet of the energy storage pipeline is connected with manual butterfly valves through the flange bolt, 10 flat nozzle-shaped air cannon nozzles are installed on two sides of the grate cooler respectively, the air quantity of the 10 nozzles is adjusted in consideration of requirements, 10 manual butterfly valves are added on the energy storage pipeline and an air cannon nozzle connecting pipeline respectively, the manual butterfly valves are welded at the inlets of the flat nozzle-shaped air cannons through pipelines, and the air cannon nozzles are positioned at a position 15 cm from the height of a grate plate inside the grate cooler and at a distance of 1 m and are embedded in a grate cooler wall.
Has the beneficial effects that: the utility model provides a cold quick-witted side blast apparatus of comb utilizes one section newly-increased fan of the cold machine of comb, and the cooling air that will produce passes through the pipe-line transportation to the cold quick-witted both sides of comb, evenly arranges 10 through the position that appears in both sides "red river" and sweeps the mouth, and the cooling air carries out rapid cooling to "red river" (fine particle grog) of the cold quick-witted grate bed upper portion both sides of comb through the nozzle, has solved the cold quick-witted both sides "red river" phenomenon of comb, and cooling efficiency obtains promoting, has also improved the life cycle of the cold quick-witted comb board of comb simultaneously.
Drawings
FIG. 1 is a schematic view of an embodiment of the present invention;
in the figure, 1 is a centrifugal fan, 2 is an air pipe, 3 is an energy storage pipeline, 4 is an air cannon nozzle, 5 is a manual butterfly valve, and 6 is a grate cooler.
Detailed Description
The invention is described in detail below with reference to the following figures and specific examples:
a grate cooler side air blowing device comprises: the method is characterized in that a centrifugal fan is installed at the front end of a grate cooler, an outlet of the centrifugal fan is connected with an air pipe through a flange bolt, two ends of the air pipe are respectively welded on energy storage pipelines installed at two sides of one section of the grate cooler, high-pressure air generated by the centrifugal fan is led to the energy storage pipelines installed at two sides of one section of the grate cooler through the air pipe to ensure that the pressure entering the interior of the grate cooler is kept constant, 10 flat-mouth-shaped air cannon nozzles are respectively and symmetrically installed at two sides of the grate cooler, 10 manual butterfly valves are respectively added on the energy storage pipelines and the air cannon nozzle connecting pipelines in consideration of the requirement for adjusting the air quantity of the 10 nozzles, one end of each flat-mouth-shaped air cannon nozzle is connected with the manual butterfly valve, the other end of each flat-mouth-shaped air cannon nozzle is directly communicated with the interior of the grate cooler, the installation position of each flat-mouth-shaped air cannon nozzle is 15 cm in height from a grate plate in the interior of the grate cooler, the interval is 1 m, and the flat-cooler is embedded in a grate cooler wall.
When the rotary kiln runs, the newly added side blowing fans of the grate cooler are started, the red river phenomenon on two sides of the grate bed is observed through the camera inside the grate cooler, 10 manual butterfly valves on two sides of the grate cooler are adjusted to ensure that clinker on two sides can be cooled in time, the Hertz number of a frequency converter of the side blowing fans is adjusted in time when the air quantity is insufficient to meet the requirement of air consumption, when the material layers on two sides are blown through, the Hertz number of the fan running is reduced in time, the optimal operating parameters are searched, the purpose of cooling red materials on two sides of the grate cooler and simultaneously avoiding too much cold air from being mixed into the grate cooler is achieved, the cooling efficiency of the grate cooler is finally improved, and the waste heat generating capacity is improved.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
