Abstract
The utility model discloses an exhaust-gas waste-heat boiler of a glass kiln. The exhaust-gas waste-heat boiler comprises a boiler barrel, a superheater, a I-type evaporator, a II-type evaporator, a coal economizer, a water heater, an inlet flue, a body flue, an outlet flue, a flash evaporator, a desuperheater, a valve, a bypass flue, a transitional flue, a denitration device, a shut-off valve and the like, wherein the shut-off valve is installed inside the transitional flue, the transitional flue is connected with the body flue, two ends of the bypass flue are connected with the body flue, and a temperature measuring instrument is installed on the body flue. The exhaust-gas waste-heat boiler has the advantages that the denitration device is used and is connected with the boiler into a whole, flues and supports are not required to be arranged in an attaching and crossing mode, the boiler is compact in structure, low in steel consumption, small in occupied area and capable of achieving the NOx emission reduction target of exhaust gases simultaneously.
Description
Technical field:
The utility model relates to a kind of high-temperature flue gas waste heat that the glass furnace production line produces that reclaims, thereby produces the waste heat boiler that steam is used for generating by heat exchange.
Background technology:
Existing glass furnace production technology is used to the high-temperature flue gas waste heat energy that produces in the glass product process, and pernicious gas NOx does not adopt an effective measure yet and realize to reduce discharging, along with the raising that both at home and abroad environmental quality control is required, the flue gas of the waste heat boiler discharging in service of existing production system configuration can not satisfy the reduction of discharging requirement that environmental protection index NOx is proposed.
Summary of the invention:
The purpose of this utility model is to provide a kind of can not only effectively reclaim the high-temperature flue gas waste heat that produces in the Improving Glass Manufacturing Processes, produces steam and is used for generating, also reduces the waste gas residual heat boiler of the pernicious gas NOx discharging of glass production line generation simultaneously.
Technical solution of the present utility model is:
A kind of glass furnace waste gas residual heat boiler, comprise drum, superheater, evaporimeter I, evaporimeter II, economizer, water heater, inlet flue duct, body flue, exhaust pass, flash vessel, attemperator, valve etc., it is characterized in that: comprise that also by-pass flue, transition flue duct, denitrification apparatus, stop valve, denitrification apparatus two ends link to each other with transition flue duct, stop valve and continuous in the body flue is housed in the transition flue duct, the by-pass flue two ends link to each other with the body flue, on the body flue temperature measuring device are housed.
By-pass flue is the flue of two groups of parallel connections, and stop valve is housed on the by-pass flue.
Between the transition flue duct before evaporimeter I and the denitrification apparatus temperature adjustment superheater is housed also.
The beneficial effects of the utility model:
The glass furnace waste gas residual heat boiler adopts denitrification apparatus, is connected as a single entity with boiler, need not attached striding and arranges flue and support, and boiler structure is compact, and the steel consumption is low, and floor space is few, has realized that simultaneously the NOx of flue gas reduces discharging target.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 is the configuration diagram of another embodiment of the utility model.
The specific embodiment:
A kind of glass furnace waste gas residual heat boiler, comprise drum 1, superheater 2, evaporimeter I 3, evaporimeter II4, economizer 5, water heater 6, inlet flue duct 7, body flue 8, exhaust pass 9, flash vessel 10, attemperator 11, valve 12 etc., it is characterized in that: also comprise by-pass flue 13, transition flue duct 14, denitrification apparatus 15, stop valve 16, denitrification apparatus 15 two ends link to each other with transition flue duct 14, stop valve 16 is housed in the transition flue duct 14, temperature measuring device 17 is housed on the body flue 8.
By-pass flue 13 is the flue of two groups of parallel connections, and stop valve 16 is housed on the by-pass flue 13.
Between the transition flue duct 14 before evaporimeter I3 and the denitrification apparatus 15 temperature adjustment superheater 18 is housed also.
The flue gas flow of non-temp .-regulating type denitrating technique is by Figure 1 shows that:
Glass kiln residual heat flue gas → inlet flue duct 7 → superheater 2 → evaporimeter I 3 → transition flue duct 14 → denitrification apparatus 15 → body flue 8 → evaporimeter II4 → economizer 5 → water heater 6 → exhaust pass 9.The flue gas flow of temp .-regulating type denitrating technique is by Figure 2 shows that:
Glass kiln residual heat flue gas → inlet flue duct 7 → superheater 2 → evaporimeter I 3 → thermoregulation water heater 18 → transition flue duct 14 → denitrification apparatus 15 → body flue 8 → evaporimeter 4 → economizer 5 → water heater 6 → exhaust pass 9.
