Abstract
The utility model relates to a kind of Boiler flue pipe protective device; comprise steel pipe and tube sheet; the external diameter of described steel pipe is slightly less than the internal diameter of Boiler flue pipe; one end of described steel pipe is welded on described tube sheet; described tube sheet is the plectane of hollow; the hollow space of described tube sheet is circular, and the diameter of described hollow space is identical with described steel pipe.The utility model is not changing under the integrally-built prerequisite of boiler, by one end concordant for described steel pipe being inserted in the flue gas inlet port of Boiler flue pipe, described steel pipe with a terminal block of tube sheet on Boiler flue pipe tube sheet, alleviate high pressure and with the flue gas of particle to the impact wear of Boiler flue pipe, alleviate the deposition of Boiler flue pipe inlet end incrustation, thus, reduce the number of times that Boiler flue pipe is changed, reduce the cleaning difficulty of Boiler flue pipe incrustation, improve the thermal efficiency, reduce production cost, improve the service life of Boiler flue pipe.
Description
Technical field
The utility model belongs to manganese sulfate preparing technical field, is specifically related to a kind of Boiler flue pipe protective device.
Background technology
In the process preparing manganese sulfate, use boiler to heat, in the use procedure of boiler, adopt the flue gas that can produce a large amount of band particles during biomass fuel combustion, when the flue gas of this band particle enters into shell and tube Boiler flue pipe, understand the junction to Boiler flue pipe and Boiler flue pipe tube sheet, and the inwall of the about 100mm of the arrival end of Boiler flue pipe causes powerful impact, this can make the junction of Boiler flue pipe and Boiler flue pipe tube sheet, and the about 100mm inwall heavy wear of the end of boiler smoke tube inlet and damaging, thus cause needing to change Boiler flue pipe, meanwhile, flue gas also can form fouling at the inwall of Boiler flue pipe intake section, and not only affect heat exchange effect and rate, the scale removal of the Boiler flue pipe after fouling is very difficult.Therefore, need to solve the number of times reducing Boiler flue pipe and change, reduce the cleaning difficulty of Boiler flue pipe incrustation, improve the thermal efficiency, reduce production cost, improve the problem in the service life of Boiler flue pipe.
Utility model content
The purpose of this utility model is solve the problems of the technologies described above and provide a kind of Boiler flue pipe protective device.
For achieving the above object, the utility model is by the following technical solutions:
A kind of Boiler flue pipe protective device; it is characterized in that; comprise steel pipe and tube sheet; the external diameter of described steel pipe is slightly less than the internal diameter of Boiler flue pipe; one end of described steel pipe is welded on described tube sheet; described tube sheet is the plectane of hollow, and the hollow space of described tube sheet is circular, and the diameter of described hollow space is identical with described steel pipe.
The internal diameter of described steel pipe is a little less than the internal diameter of Boiler flue pipe, and wall thickness is 2.5mm.
The length of described steel pipe is 70-100mm.
The utility model is not changing under the integrally-built prerequisite of boiler, by one end concordant for described steel pipe being inserted in the flue gas inlet port of Boiler flue pipe, described steel pipe with a terminal block of tube sheet on Boiler flue pipe tube sheet, alleviate high pressure and with the flue gas of particle to the impact wear of Boiler flue pipe, alleviate the deposition of Boiler flue pipe inlet end incrustation, thus, reduce the number of times that Boiler flue pipe is changed, reduce the cleaning difficulty of Boiler flue pipe incrustation, improve the thermal efficiency, reduce production cost, improve the service life of Boiler flue pipe.
Accompanying drawing explanation
Fig. 1 is depicted as the structural representation of a kind of Boiler flue pipe protective device that the utility model embodiment provides;
Figure 2 shows that the structure chart of steel pipe.
Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but the utility model is not limited to listed embodiment.
Refer to Fig. 1, this Fig. 1 has shown the structure of a kind of Boiler flue pipe protective device that the utility model embodiment provides.For convenience of explanation, illustrate only the part relevant with the utility model embodiment.
Refer to shown in Fig. 1 ~ 2, a kind of Boiler flue pipe protective device, comprise steel pipe 7 and tube sheet 6, the concordant one end of steel plate 6 is inserted in the smoke inlet end 4 of Boiler flue pipe 1, and the tube sheet 6 of the other end of steel pipe 7 is stuck on Boiler flue pipe tube sheet 2; When boiler smoke from
Multiple flues 1 that described Boiler flue pipe comprises tube sheet 2 and connects with described tube sheet, described tube sheet has the multiple flue gas inlet ports communicated with described flue, detachable suit one steel pipe 3 in flue gas inlet port described in each, the main part 7 of described steel pipe stretches in described flue 1, and is stuck in described flue gas inlet port by boss 6.When the smoke inlet end 4 of boiler smoke from Boiler flue pipe 1 enters; and when being discharged by flue gas outlet side 5; first through described steel pipe 7, and then enter Boiler flue pipe 1, can realize like this being protected by described steel pipe 7 pairs of Boiler flue pipes 1 and Boiler flue pipe tube sheet 2.
The utility model is not changing under the integrally-built prerequisite of boiler, by one end concordant for described steel pipe being inserted in the flue gas inlet port of Boiler flue pipe, described steel pipe with a terminal block of tube sheet on Boiler flue pipe tube sheet, alleviate high pressure and with the flue gas of particle to the impact wear of Boiler flue pipe, alleviate the deposition of Boiler flue pipe inlet end incrustation, thus, reduce the number of times that Boiler flue pipe is changed, reduce the cleaning difficulty of Boiler flue pipe incrustation, improve the thermal efficiency, reduce production cost, improve the service life of Boiler flue pipe.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
