Abstract
The utility model discloses a waste heat recovery system of a grate cooler. The waste heat recovery system of the grate cooler comprises the grate cooler which is composed of a first section, a second section and a third section, wherein a first waste heat power generation connector is arranged on a shell on the top of a grate plate of the first section of the grate cooler, a second waste heat power generation connector and a coal air connector are arranged on a shell on the top of a grate plate of the second section of the grate cooler, a remaining air connector is arranged on a shell on the top of a grate plate of the third section of the grate cooler, concrete retaining walls are arranged on the front wall and the rear wall, corresponding to the third section of the grate cooler, of the shell on the top of the third section of the grate cooler respectively, and a steel plate retaining wall is arranged at the bottom of the position between the two concrete retaining walls. In order to increase the amount of electricity generated through waste heat, the steel plate retaining wall is designed to be arranged at the bottoms of the original concrete retaining walls of the grate cooler, and is composed of three steel plates, the length of each steel plate is 1400 mm, and the distance between the lower end of the steel plate retaining wall and the upper surface of the grate plate of the third section is 800 mm; the steel plate retaining wall is used for preventing a large amount of low-temperature air in the third section of the grate cooler from entering the second section, the temperature of air, for waste heat power generation, in the first section and the temperature of air, for waste heat power generation, in the second section are increased, and the quantity of electricity generated through clinker per ton is increased by 3 kilowatt-hours to 4 kilowatt-hours, and considerable economic benefit and considerable social benefit are created.
Description
Technical field
Cement plant manufacturing technique requirent rotary kiln clinker discharging needs chilling, conventionally reaches the object of grog chilling by grate-cooler.For energy-saving and cost-reducing, utilize grate-cooler cogeneration, improving cogeneration amount is a job of paying special attention to all the year.The utility model relates to a kind of grate-cooler cogeneration amount device.
Background technology
The grate-cooler of cement plant chilling clinker discharging, the remainder of the hot blast of generation except kiln utilization is used for generating electricity, and cogeneration amount is a production performance assessment criteria in cement plant.Since my company's cement producing line is gone into operation, in the situation that other production targets are stable, improving cogeneration amount is a regular job.Carefully analyzing production technology, the wind that three sections of temperature of grate-cooler are lower can enter 2 sections in a large number, thereby reduces by 1,2 section of wind-warm syndrome that enters cogeneration.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency a kind of grate-cooler residual neat recovering system is provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of grate-cooler residual neat recovering system, comprise grate-cooler, formed by I section, II section and III section at grate-cooler, on the housing at the grate plate top of grate-cooler I section, be provided with I cogeneration interface, on the housing at the grate plate top of grate-cooler II section, be provided with II cogeneration interface and coal wind interface, on the housing at the grate plate top of grate-cooler III section, be provided with lingering remnants of past customs interface, on the front and rear wall of the top shell of grate-cooler III section correspondence, be provided with concrete guard wall, the bottom between two concrete guard walls is provided with steel plate barricade.
Above-mentioned grate-cooler residual neat recovering system, the distance between the bottom of steel plate barricade and grate-cooler grate plate is 800mm.
Above-mentioned grate-cooler residual neat recovering system, described steel plate barricade is arranged on round steel by connecting plate, and round steel is set on steel pipe, and the two ends of steel pipe are fixed on the front and back wallboard of concrete guard wall bottom.
Adopt technique scheme, the utility model has following advantage: be to improve cogeneration amount, in the former concrete guard wall bottom design of grate-cooler steel plate barricade: steel plate barricade is made up of 3 length 1400mm steel plates, and lower end is 800mm above grate plate.Block the lower wind of 3 sections of temperature of grate-cooler with steel plate barricade and enter in a large number 2 sections, thereby improve 1,2 section of wind-warm syndrome that enters cogeneration, improve ton grog generated energy 3～4 degree.Considerable economic benefit and social benefit are created.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the right view of Fig. 1 steel plate barricade.
Fig. 3 is Fig. 1 light plate barricade and front-back wall board connecting structure figure.
The specific embodiment
A kind of grate-cooler residual neat recovering system as shown in Figure 1 to Figure 3, comprise grate-cooler, at grate-cooler by I section, II section and III section form, on the housing at grate plate 1 top of grate-cooler I section, be provided with I cogeneration interface 7, on the housing at the grate plate top of grate-cooler II section, be provided with II cogeneration interface 6 and coal wind interface 5, on the housing at the grate plate top of grate-cooler III section, be provided with lingering remnants of past customs interface 4, on the front and rear wall of the top shell of grate-cooler III section correspondence, be provided with concrete guard wall 3, bottom between two concrete guard walls is provided with steel plate barricade 2, distance between the bottom of steel plate barricade 2 and grate-cooler grate plate is 800mm.
