Abstract
The invention relates to a resistance type electric heating hot water boiler, belonging to the technical field of a boiler. A boiler cylinder body is formed by welding a boiler cylinder, a front seal head, and a rear seal head; a gas collecting pot is connected with a water outlet valve by a flange; an electric heating pipe protecting cover and a boiler supporting base are welded at the outer part of the boiler cylinder; an electric heater is connected to an electric heating pipe interface by bolts, a safety valve is fixed on a safety valve pipe base by bolts; a pressure gage interface, an electric heating pipe interface, the safety valve base, a water outlet valve base, a manhole, a temperature meter interface, a water returning valve, and a blowoff valve base are welded to the boiler cylinder and are communicated with one another; the outer part of the boiler cylinder is provided with a boiler to preserve temperature. The resistance type electric heating hot water boiler has the following beneficial effects that: 1. the problems of low heat efficiency of the boiler is solved to save energy; 2, the environment-friendly problem is solved; 3. the labor is saved and the labor intensity of an operator is lightened; 3. the history of 4.2 MW/h of the evaporation capacity of a resistance type electric heating steam boiler is broken through.
Description
Technical field
The present invention relates to resistance-type electrical heating hot-water boiler, belong to the boiler technology field.
Background technology
China 85% is coal-burning boiler nearly in Industrial Boiler, and China's coal-burned industrial boiler is main with the grate firing burning, and is main with chain grate boiler; Boiler design efficient is generally between 72% ~ 80%, but the ubiquity operating load is low than the boiler rated load during actual motion, and boiler slag carbon content is high; Excess air coefficient is big; Exhaust gas temperature is high, and therefore, the thermal efficiency is generally low than design efficiency.The thermal efficiency of the grate firing coal-burning boiler of external advanced country can reach 80% ~ 85%, and some boiler put into operation two, 30 years, still can keep the very high thermal efficiency.Because China's fuel structure makes coal-burned industrial boiler become one of primary pollution source of China's atmosphere coal smoke shape pollution.Ten thousand tons of the about 600-800 of the smoke discharge amount in the every year of Industrial Boiler account for 33% of national flue dust total release; SO
2Discharge capacity be about the 500-600 ton, account for 21% of national total release; CO
2Discharge capacity be about 600,000,000 tons, and a large amount of NO
X
At present; The development trend of China's boiler industry is to improve atmospheric environment, raising energy utilization rate more and more to be all trades and professions and government agencies at all levels' concern; Technology such as reduction of discharging, flue gas desulfurization, coal gasification are used widely; Superseded coal-burning boiler becomes trend of the times, the electrically heated boiler of energy-saving and environmental protection just winning boiler market and government regulator favor.The resistance-type electrical heating steam boiler evaporation capacity of current domestic maximum is 4.2MW/h, and the CO that the annual discharging of Industrial Boiler causes the environment greenhouse effects has been mentioned in the front
2Amount be about 600,000,000 tons, and reduce CO
2The effective ways of discharging are the efficient that improves boiler.The automatic monitoring of boiler is not only the extremely important means that guarantee boiler safety with automatic control, but also in the control boiler combustion, improves boiler efficiency and aspect of performance and play important effect.
Summary of the invention
In order to overcome above-mentioned deficiency, the object of the present invention is to provide resistance-type electrical heating hot-water boiler, its evaporation capacity is 5.6MW/h, it breaks through resistance-type electrical heating steam boiler evaporation capacity is the history of 4.2MW/h.
The present invention is by electric heating tube protective cover, boiler saddle, electric heater, front head, pressure gauge connection, emergency valve seat, water outlet valve seat, air collector, manhole, drum, rear head, boiler insulation, thermometer boss, backwater valve seat, blowdown valve seat; Boiler barrel is welded to form by drum, front head, rear head; Air collector adopts flange to be connected with the water outlet valve seat; Electric heating tube protective cover, boiler saddle are welded on the outside of drum; Electric heater adopts bolt to be connected on the electric heating tube interface; Safety valve adopts and is bolted on the safety valve base, and pressure gauge connection, electric heating tube interface, emergency valve seat, water outlet valve seat, manhole, thermometer boss, backwater valve seat, blowdown valve seat all are welded on the drum and are communicated with, and in the boiler barrel outside boiler insulation are arranged.
Beneficial effect of the present invention: it is low 1, to have solved the thermal efficiency of boiler, problem of energy saving; 2, separate the problem of fast environmental protection.3, save manpower and alleviated operator's labour intensity.3, breaking through resistance-type electrical heating steam boiler evaporation capacity is the history of 4.2MW/h.
Advantage of the present invention: the resistance heating principle is adopted in this invention, utilizes electric heater to convert electric energy to heat energy, thereby has improved the thermal efficiency of boiler, reaches more than 98%; Resistance-type electrical heating hot-water boiler adopts full-automatic PLC to control system.The thermal efficiency of resistance-type electrical heating hot-water boiler is high, and electric power energy does not have waste gas, waste sludge discharge, non-environmental-pollution; Electric pole type electrical heating hot-water boiler adopts full-automatic PLC control, saves manpower and has alleviated operator's labour intensity.
The attainable function of boiler control system:
1 full-automatic computer boiler switch board, changeable one-tenth is manual;
2 temperature anomalies are reported to the police and fault shows;
3 water level abnormalities are reported to the police and fault shows;
4 ability autostop and warnings are to guarantee system safety operation;
5 can follow the trail of load automatically, can in time adjust the boiler operatiopn state according to the variation of load;
6 boilers have self-checking function, and show self check information.
7 all boiler operatiopn state and fault alarms all can show on display panels.
8 are equipped with the telecommunication international standard interface; Can make progress each association, the communications protocol of level controlling system instantaneous transmission boiler operating state, and can with the control systems connection, realize Long-distance Control debugging and operation; The Centralized Monitoring of ability realization equipment and subsidiary engine, all Chinese and English shows.
Operation principle: system's backwater gets into boiler from water circulating pump through the backwater valve seat, and backwater flows through electric heater, and hot user is supplied with by the water outlet valve seat in water heating back.
