Abstract
The utility model discloses a kind of waste heat boiler defroster, it comprises heating muff, electric heating tube, temperature sensor, heating tube temperature switch, the described heating muff of described temperature sensor and more than one is provided with at the inner chamber of preboiler, in heating muff described in every root, be provided with a described electric heating tube, described electric heating tube and described temperature sensor are connected with described heating tube temperature switch respectively.Advantage is: in the waste heat boiler that cold district cement industry uses, install defroster additional ensure do not having waste heat for seasonable, will not bleed off by boiler water, saving water resource, ensure that pot in-furnace temperature remains at more than 20 DEG C, can come into operation at any time, do not affect manufacturing schedule, reduce maintenance cost.
Description
Technical field:
The utility model relates to a kind of waste heat boiler corollary equipment, particularly relates to a kind of waste heat boiler defroster
Background technology:
The waste heat boiler that cement industry uses utilizes cement rotary kiln waste heat to generate electricity; at cold districts such as the north; when rotary system carry out safeguarding or break down etc. need to shut down time; just boiler water can only be bled off, prevent boiler tube bursting by freezing from damaging, but when discharging water; have in part boiler tube that to have seeping phenomenon to put unclean; still there will be the phenomenon of boiler tube bursting by freezing, have a strong impact on manufacturing schedule, increase maintenance cost simultaneously.
Utility model content:
The purpose of this utility model is to provide a kind of defroster that installs additional in the waste heat boiler that cold district cement industry uses to ensure do not having waste heat for seasonable, will not bleed off by boiler water, can come into operation at any time, not affect manufacturing schedule, reduce the waste heat boiler defroster of maintenance cost
The utility model is implemented by following technical scheme: waste heat boiler defroster, it comprises heating muff, electric heating tube, temperature sensor, heating tube temperature switch, the described heating muff of described temperature sensor and more than one is provided with at the inner chamber of preboiler, in heating muff described in every root, be provided with a described electric heating tube, described electric heating tube and described temperature sensor are connected with described heating tube temperature switch respectively.
Advantage of the present utility model: install defroster additional and ensure do not having waste heat for seasonable in the waste heat boiler that cold district cement industry uses, will not bleed off by boiler water, saving water resource, ensure that pot in-furnace temperature remains at more than 20 DEG C, can come into operation at any time, do not affect manufacturing schedule, reduce maintenance cost.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is connection control figure of the present utility model.
Heating muff 1, electric heating tube 2, temperature sensor 3, heating tube temperature switch 4, preboiler 5, manufacture of cement DCS system 6.
Detailed description of the invention:
As depicted in figs. 1 and 2, waste heat boiler defroster, it comprises heating muff 1, electric heating tube 2, temperature sensor 3, heating tube temperature switch 4, the heating muff 1 of more than temperature sensor 3 and one is provided with at the inner chamber of preboiler 5, electric heating tube 2 is provided with in heating muff 1, electric heating tube 2 is arranged in heating muff 1 and effectively prevents wearing and tearing and system air leakage, electric heating tube 3 is connected with heating tube temperature switch 4 respectively with temperature sensor 3, heating tube temperature switch 4 controls electric heating tube 3 according to the temperature signal that temperature sensor 3 collects and works, when the minimum setting value of temperature lower than heating tube temperature switch 4, electric heating tube 3 starts to heat, when the high setting value of temperature lower than heating tube temperature switch 4, electric heating tube 3 stops heating, , heating tube temperature switch 4 can be connected with manufacture of cement DCS system 6, controls the duty of electric heating tube 2 by manufacture of cement DCS system 6 real time monitoring.
