Abstract
The utility model relates to the waste gas recovering device being applicable to roller drying machine, comprises deduster and air-introduced machine; Also comprise the air preheater be arranged between deduster and air-introduced machine, and the blower fan be connected with air preheater; Described air preheater comprises the metal box being arranged to rectangular-shaped hollow, roundabout laying blast pipe in metal box, and the outlet of blast pipe is connected with blower fan by pipeline; Described blower fan is connected with thermal source producer by appendix.This waste gas recovering device is simple for structure, avoids the waste of the energy, meanwhile, also avoids making the blade of air-introduced machine be subject to the damage of high-temp waste gas, extends the service life of relevant device, reduce production cost.
Description
Technical field
The utility model relates to oven dry plant equipment, particularly relates to the waste gas recovering device being applicable to roller drying machine.
Background technology
Roller drying machine is the normal plant equipment used in current existing oven dry industry, and the rotating cylinder of roller drying machine slightly tilts and the pivotal cylinder of energy, and wet stock enters from top, one end, and dry material is from other end collective low.Hot blast enters from feed end or discharge end, discharges from other end top.Cylinder, built with forward flight, under material is constantly taken up in cylindrical shell turning course and spilling, makes it fully contact with thermal current, to improve drying efficiency and to make material move forward.Dried material thermal source is generally hot-air, high-temperature flue gas, steam etc.In existing drying plant, thermal source becomes waste gas after rotating cylinder is by drying materials, and waste gas, under the effect of air-introduced machine, after extracting out, first through deduster dedusting, after the dust-filtering in waste gas, more directly discharges air through air-introduced machine in rotating cylinder.But at present, the temperature of waste gas is normally at about 80-100 DEG C, the waste gas of so direct discharge will cause the significant wastage of the energy, and the waste gas of high temperature also can damage air-introduced machine, cause reduce the service life of air-introduced machine, need often maintenance or change air-introduced machine, also causing the production cost of enterprise high.
Summary of the invention
For the defect of prior art, the utility model proposes the waste gas recovering device being applicable to roller drying machine, by the heat recovery in waste gas, the waste of the energy can be avoided, meanwhile, increase the service life of air-introduced machine, reduce the production cost of enterprise.
For achieving the above object, the utility model proposes the waste gas recovering device being applicable to roller drying machine, comprise deduster and air-introduced machine; Also comprise the air preheater be arranged between deduster and air-introduced machine, and the blower fan be connected with air preheater; Described air preheater comprises the metal box being arranged to rectangular-shaped hollow, roundabout laying blast pipe in metal box, and the outlet of blast pipe is connected with blower fan by pipeline; Described blower fan is connected with thermal source producer by appendix.
The space of described blast pipe complexed metal case inside is roundabout to be arranged in metal box, and blast pipe comprises air inlet and gas outlet; The circular hole arranging a through metal box outer wall in described metal box upper end, as air inlet, also arranges one and also arranges the circular hole of a through metal box outer wall as gas outlet in metal box lower end; Described air inlet is communicated with air by one section of metal tubes, and the pipeline be connected with blower fan to be coordinated with metal box by gas outlet and is fixedly connected with.
The inwall of described blast pipe complexed metal case is roundabout is laid in metal box inside.
The outer wall of described air preheater is equipped with heat-insulation layer.
Beneficial effect
The air preheater of the utility model by arranging, make waste gas after deduster dedusting, enter in metal box, blast pipe is communicated with air, under the effect of blower fan, air lower for temperature is pumped in blast pipe, cold air in blast pipe and the hot-air in metal box are after heat exchange, the temperature of waste gas is reduced, air temperature in blast pipe is raised, waste gas after cooling is discharged through air-introduced machine again, under the effect of air in blast pipe after heating at blower fan, enter in thermal source producer, avoid the waste of the energy, simultaneously, also avoid making the blade of air-introduced machine be subject to the damage of high-temp waste gas, extend the service life of relevant device, reduce production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in the figure, be applicable to the waste gas recovering device of roller drying machine, comprise deduster 1 and air-introduced machine 3; Also comprise the air preheater 2 be arranged between deduster 1 and air-introduced machine 3, and the blower fan 4 be connected with air preheater 2; Described air preheater 2 is the metal boxes being arranged to rectangular-shaped hollow, roundabout laying blast pipe in metal box, and blast pipe is connected with blower fan 4 by pipeline 6; Described blower fan 4 is connected with thermal source producer 5 by appendix.The space of described blast pipe complexed metal case inside is roundabout to be arranged in metal box, and blast pipe comprises air inlet 21 and gas outlet 22; The circular hole arranging a through metal box outer wall in described metal box upper end, as air inlet 21, also arranges one and also arranges the circular hole of a through metal box outer wall as gas outlet 22 in metal box lower end; Described air inlet 21 is communicated with air by one section of metal tubes, and the pipeline 6 be connected with blower fan 4 to be coordinated with metal box by gas outlet 22 and is fixedly connected with.The inwall of described blast pipe complexed metal case is roundabout is laid in metal box inside.The outer wall of described air preheater 2 is equipped with heat-insulation layer.Heat-insulation layer can ensure that the heat in metal box does not scatter and disappear, and makes air inlet pipe obtain better heat transfer effect.
Waste gas out, enters into deduster 1 in rotating cylinder 7.Use the metal box of cuboid as air preheater 2, one end of metal box arranges circular hole, and the flue gas leading exported from deduster 1 to be coordinated with metal box by circular hole and is fixed and welded together; Corresponding one end of metal box arranges same circular hole, uses the pipeline of coupling to coordinate the circular hole of this end to be connected with air-introduced machine 3.The blower fan 4 be connected with thermal source producer 5 by appendix can be air blast, cold air is pumped in the air inlet pipe of metal box inside by air blast, the cold air in air inlet pipe and the hot-air in metal box is made to carry out sufficient heat exchange, finally, be input in thermal source producer 5 by the air in blast pipe after heat exchange again, supplying heat source producer 5 uses.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
