Description

Network control pressureless energy-saving type water heater

Technical field:

The utility model relates to a kind of direct-fired water heater, specifically a kind of network control pressureless energy-saving type water heater.

Background technology:

Present school, factories and miness, army, army, hospital, the boiling water supply in hotel etc. all adopts tradition that the heating of pressure type boiler is arranged basically, and BTHE is low, and discharging is high, the investment height, the operating cost height, high-pressure boiler also has certain potential safety hazard simultaneously.For some units in dense population areas, be very unsafe if use pressure boiler to supply water, but also special kettleman will be arranged, also just increase the operating cost of unit.Water heater is fuel used to be coal, inconvenient operation, and labour intensity is big, and has sulfur dioxide to produce contaminated environment in smoke evacuation.

Now also there is the good nothing of some safety to press off hydrophone, owing to be that a water tank adopts the float-ball type taps, its shortcoming is exactly that boiling water decline ball float and then descends, the ball float taps is opened and cold water is inserted water tank is mixed with original boiling water, cause to cause directly being emitted without the water of scalding and drink, the harm people's is healthy.

In addition, just heating because some water heaters such as have only to put to be at boiling water, just caused the batch (-type) way of supplying water, usually is that people need wait in line, and has reduced operating efficiency.

In a word, mainly there are two big drawbacks in existing water heater, and the one, the thermal efficiency is low, and emission easily causes environmental pollution; The 2nd, be difficult to realize unmanned, caused labour's waste, also just increased use cost.

The utility model content:

For overcoming the defective of prior art, the purpose of this utility model be to provide a kind of efficiency of utilization high, that water application efficiency is high and safe and reliable, can realize unattended network control pressureless energy-saving type water heater.

The utility model technical solution problem adopts following technical scheme:

Network control pressureless energy-saving type water heater, described water heater has burner hearth and is located at the outer water interlayer of burner hearth, burner hearth is located at water heater body's below, the water heater body of burner hearth top is divided into two parts by a dividing plate, promptly the heating clamber that is communicated with water interlayer and with the disconnected preheating chamber of water interlayer, many flues of being communicated with burner hearth are through heating clamber, preheating chambers and be arranged on the interior chimney of preheating chamber and be communicated with;

Described water heater also has water inlet that is arranged on the preheating chamber middle part and the delivery port that is arranged at heating clamber top;

Described water heater also has a connecting pipe, and the end of this communicating pipe is communicated with the water interlayer of burner hearth bottom, and the inlet of the other end places the top of preheating chamber.

Also be provided with some standpipes in the described burner hearth, the standpipe lower port is communicated with the water interlayer of burner hearth bottom, and the standpipe upper port is stretched out burner hearth and is positioned at heating clamber.

The water inlet of described water heater is communicated with feed pipe by magnetic valve.

The below of described water heater delivery port is provided with temperature sensor, and temperature sensor and magnetic valve are electrically connected with controller.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

Water heater of the present utility model adopts the wetting back-type burner hearth, be that burner hearth is water interlayer outward, water heater body's bottom is a burner hearth, top is divided into heating clamber and preheating chamber by a dividing plate, flue passes through heating clamber respectively, the preheating chamber chimney interior with being arranged on preheating chamber is communicated with, high-temperature fuel gas is when the burner hearth internal combustion, can rapidly the water in water interlayer and the heating clamber be heated, the high-temperature flue gas of discharging is finished heat exchange for the second time with water in heating clamber, the flue gas after the cooling carries out heat exchange with water once more in preheating chamber, and with water preheat, therefore, discharging the contained heat of flue gas can be absorbed by water substantially fully, has improved the thermal efficiency of water heater greatly, and total heat exchange area improves 1/3, flue gas flow length is many 1/4, the heating power exchange is abundant, and flue-gas temperature reduces by 60 ℃, and the thermal efficiency reaches more than 90%.

Also be provided with some standpipes in the burner hearth, the standpipe lower port is communicated with the water interlayer of burner hearth bottom, the standpipe upper port is stretched out burner hearth and is positioned at heating clamber, high-temperature fuel gas is when the burner hearth internal combustion, water in the standpipe heats up the fastest, according to the principle that hot water upwards flows, the existence of standpipe can be quickened the water circulation in the heating clamber, thereby can improve the rate of heat exchange of water and combustion gas.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a left view of the present utility model.

Number in the figure: 1 burner hearth, 2 water interlayers, 3 dividing plates, 4 heating clambers, 5 preheating chambers, 6 flues, 7 chimneys, 8 standpipes, 9 water inlets, 10 magnetic valves, 11 delivery ports, 12 temperature sensors, 13 controllers, 14 communicating pipes.

Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.

The specific embodiment,

Non-limiting examples is as described below:

Embodiment: Fig. 1, shown in 2, the water heater of present embodiment has burner hearth 1 and is located at the outer water interlayer 2 of burner hearth, burner hearth 1 is located at water heater body's below, the water heater body of burner hearth 1 top is divided into two parts by a dividing plate 3, promptly the heating clamber 4 that is communicated with water interlayer 2 and with the disconnected preheating chamber 5 of water interlayer, many flues 6 (can set according to the size of water heater by number, 6-10 root for example) passing dividing plate 3 levels puts in heating clamber 3 and preheating chamber 5, one end of flue 6 is communicated with burner hearth 1, the other end is communicated with the chimney 7 that is arranged in the preheating chamber 5, also be provided with some standpipes 8 in the burner hearth 1, the lower port of standpipe 8 is communicated with the water interlayer of burner hearth bottom 2, and the upper port of standpipe 8 is stretched out burner hearth 1 and is positioned at heating clamber 4.
