Description

A kind of steam heating type water heater

Technical field: the utility model belongs to the water heater technical field, particularly a kind of steam heating type water heater.

Background technology: water heater commonly used at present is generally coal furnace, and the heat utilization efficiency of coal furnace is low, and water temperature rises slow, and the constant temperature weak effect needs coal, slags tap in the operation, and labour intensity is big, easily causes air pollution, is difficult to realize continuous water supply.It is also more to adopt electrically heated water heater to use at present, because it is too big that its heat exchange area can not design, so exchange capability of heat is little, the hot water amount is few, the temperature of hot water is low, generally be difficult to reach more than 90 degree, and cleaning, maintenance difficult, the life-span is short, the cost height, hot water cost height is difficult to realize concentrating a large amount of water supply, can only be used to the place fewer in number of supplying water.

The steam-heated water heater of the employing that has occurred, its primary structure be, is provided with one or more groups serpentine coil in a container, when steam from coil pipe by the time, the water in the heating container.The shortcoming of the Steam Heating water heater of this structure is that heat exchange efficiency is low, and water temperature rises slow, can not continuous heat supply water, and output is restricted.

Summary of the invention: the technical problems to be solved in the utility model is, existing Steam Heating water heater heat exchange efficiency is low, can not continuous heat supply water, and output is restricted.

The technical scheme of the utility model technical solution problem is, comprise cylindrical shell, establish thermometer, liquid level gauge, sewage draining exit on the cylindrical shell, cylindrical shell is divided into four sections, be followed successively by preheating section, hot water section, heat exchanging segment, mixer from top to bottom, preheating section is established the filler, and downcomer passes hot water section, heat exchanging segment, preheating section and mixer are communicated with, make the water in the preheating section directly enter mixer; The hot water section is located under the preheating section, which is provided with hot water outlet, is provided with Steam Pipe on the hot water section top; Being provided with circulating reflux pipe and many tubulations of being communicated with hot water section and mixer in the heat exchanging segment, realizing the water of mixer and hot water section's water circulation, establish steam inlet and discharge outlet on the heat exchanging segment, is steam channel between circulating reflux pipe in the heat exchanging segment and the pipe between tubulation.

For making full use of waste heat and compact conformation, Steam Pipe is located in the preheating section, and the lower end of Steam Pipe is located on the base plate of preheating section, is communicated with the hot water section, and upper end open is higher than the water level in the preheating section, establishes drain at the preheating section top.

Downcomer is located at the centre of cylindrical shell.

The circulating reflux pipe is located at the centre of heat exchanging segment, and downcomer passes through from the centre of circulating reflux pipe, and tubulation is arranged at around the circulating reflux pipe equably.

The utility model utilizes high-temperature steam to emit whole latent heat in condensation process to carry out heat exchange by heat conduction and heat convection and cold water, realize adding the purpose of hot water.Cold water arrives preheating section through water inlet, realize preheating at preheating section through base plate (top board of hot water section) conduction hot water section's heat, water after the preheating enters the downcomer in the upper shed of preheating section base plate, in downcomer, pass the hot water section, heat exchanging segment enters mixer, in mixer on enter the tubulation of heat exchanging segment, steam enters from the steam inlet on heat exchanging segment top, walk between the pipe of heat exchanging pipe, with the water heat exchange in the tubulation, discharge through discharge outlet from the bottom after the condensation, water after the heat exchange enters the hot water section, and hot water is owing to the temperature difference produces power in the hot water section, and hot water is reduced to mixer again through the circulating reflux pipe and repeated above-mentioned heat transfer process.Several times behind the cycle heat exchange, water reaches desired temperature.Along with hot water temperature's rising, the temperature difference of hot water and steam is dwindled, and heat exchange rate reduces.The condensing rate of steam also reduces.Along with the minimizing of hot water taking-up amount, the inlet of steam reduces, and has reached self-control, has avoided the loss of heat energy.The steam that forms in gas of discharging when adding water and the hot water section is discharged through Steam Pipe, evacuation port.

The utility model is a four-part form Natural Circulation Steam Heating water heater, and running water can be heated to can be for the hot water that the people drinks or other need.This water heater need not with coal and electricity, as long as there is the place of steam and running water to install and use.The utility model is of many uses, and the place that the crowd of being widely used in concentrates is specially adapted to the local drinking water that crowds such as factory, school, hospital concentrate.This water heater volume is little, take up an area of less, cost is low, simple to operate, and establishing can unmanned guard behind liquid level regulating tank and the steam trap.Energy savings, the hot water expense is low, and is pollution-free.Hot water water withdrawal scope of design is big, can fetch water continuously, and thermal efficiency height, quick heating, hot water cost are low, environmental protection, do not have any pollution.
