Abstract
The utility model relates to an electric heating scale-free water boiler, which is composed of a drum, an electric heating tube, a front and a rear shell covers, screw thread heat exchange tube, a front and a rear collection boxes, an outlet pipe, a return pipe, etc., wherein, the upper part of the drum is provided with the screw thread heat exchange tube, and the screw thread heat exchange tube connects respectively the front and the rear shell covers and is communicated with the front and the rear collection boxes out of the front and the rear shell covers. The boiler practises a two-way water circulation system through adopting a heat pipe principle to solve thoroughly problems that the surface of the electric heating tube of the water boiler which is heated by electricity scales and the boiler has oxygen corrosion.
Description
The utility model belongs to industrial hot water boiler's technical field, relates in particular to a kind of electrical heating hot-water boiler.
At present, the circulation theory that domestic and international conventional electric heating hot-water boiler generally adopts is: the heat supply network backwater is directly sent in the boiler by the water circulating pump in the system, and these recirculated waters absorb heat to heat up in boiler and reach rated temperature, are sent to the user again.This boiler all enters again in the boiler because quantity of circulating water is very big, therefore, is in operation, and the electric heating tube fouling of boiler is serious, and not only influence is conducted heat, and the safety that jeopardizes the boiler electric heating tube, and accident frequently takes place.Also exist the oxygen corrosion that is difficult to overcome simultaneously, shortened boiler life greatly.
The purpose of this utility model is to provide a kind of electric heating not have dirty hot-water boiler, to solve existing electric hot water boiler electrothermal tube surface scale and drum oxygen corrosion problem.
For achieving the above object, adopt following technical scheme: electric heating does not have dirty hot-water boiler and contains drum, electric heating tube, front head, rear head, outlet pipe, return pipe, front head and rear head link by drum, electric heating tube is positioned at the drum bottom, it is characterized in that drum top is furnished with the screw thread heat exchanger tube, the front and back end of screw thread heat exchanger tube connects forward and backward end socket respectively, and is communicated with the forward and backward collection box of end socket outside, front and back, and outlet pipe and return pipe are communicated with the back collection box.
Below in conjunction with the embodiment accompanying drawing the utility model is described in further detail.
Fig. 1 is the structural representation that electric heating does not have dirty hot-water boiler.
By Fig. 1, electric heating does not have dirty hot-water boiler by drum (1), front head (2), rear head (3), screw thread heat exchanger tube (4), preceding collection box (5), back collection box (6), electric heating tube (7), outlet pipe (8), return pipe (9), water level meter (10) is formed, front head (2) links by drum (1) with rear head (3), electric heating tube (7) is positioned at drum (1) bottom, screw thread heat exchanger tube (4) is arranged in the vapor space on drum (1) top, the front and back end of screw thread heat exchanger tube (4) is respectively with preceding, rear head (2), (3) link to each other, and with preceding, back collection box (5), (6) be communicated with.Outlet pipe (8) and return pipe (9) communicate with back collection box (6).Water level meter (10) communicates with drum (1).
The purpose of this utility model is achieved in that electric heating does not have dirty hot-water boiler and is based on heat pipe principle, we are considered as a heat pipe with whole boilers heated electrically, the electric heating tube of boiler (7) is considered as the bringing-up section of heat pipe, the screw thread heat exchanger tube (4) that drum (1) top vapor space is arranged is considered as the cooling section of heat pipe, and the stove water in the boiler is considered as the working medium of heat pipe.The intensification of in bringing-up section, absorbing heat of stove water, reach vaporization, steam is pooled to the vapor space on drum (1) top, by condensation heat with recirculated water in the heat transferred screw thread heat exchanger tube (4), condensate water continues the heating vaporization owing to the gravity effect converges in bringing-up section, the heat supply network backwater enters back collection box (6) by return pipe (9), enters heat absorption in the screw thread heat exchanger tube (4) again, reaches rated temperature and is sent to the heat supply network user by outlet pipe (8).The operating pressure that changes boiler can change the output temperature of hot water.
Stove water in the boiler belongs to disposable adding, boiler is in operation stove water owing to be isolated from the outside and do not lose substantially, therefore, all the time have only these water in the boiler in work, because these water number amounts are limited, the total amount of the scale forming matter in the water also is limited so, as long as boiler is done an amount of blowdown at initial operating stage, can think that the stove water in the boiler has been pure water, therefore, boiler is in operation the electrothermal tube surface with non flouling behaviour.
As everyone knows, oxygen content in the water and the temperature in the water have much relations, and water temperature is high more, and the oxygen content in the water is low more.Because the stove water conservancy project is made temperature more than 105 ℃ in the boiler, and in saturation state, the oxygen content in the water is extremely low, therefore, can not form corrosion to the boiler drum surface.This boiler has fundamentally solved the same topic of existing electric hot water boiler electrothermal tube surface scale and drum oxygen corrosion.
Claims (2)
1, electric heating does not have dirty hot-water boiler, contain drum, electric heating tube, front head, rear head, outlet pipe, return pipe, front head and rear head link by drum, electric heating tube is positioned at the drum bottom, it is characterized in that heat exchanger tube is arranged at drum top, the front and back end of heat exchanger tube connects the front and back end socket respectively, and is communicated with the front and back collection box of end socket outside, front and back, and outlet pipe and return pipe are communicated with the back collection box.
