Abstract

The utility model provides an energy-saving waste heat utilization boiler which is provided with a boiler body and a chimney arranged outside the boiler body, wherein a smoke outlet of the boiler body is communicated with the chimney through a smoke exhaust pipe, an energy saver which can use waste heat of smoke to preheat cold water is arranged at the upper part of the chimney, a water supply pipe is communicated with the lower part of the energy saver, one end of a water outlet pipe is communicated with the upper part of the energy saver, and the other end of the water outlet pipe is communicated with a water clamp layer in the boiler body. According to the energy-saving waste heat utilization boiler, the exhausted waste heat of the smoke is used sufficiently to preheat the cold water, then the cold water flows into the water clamp layer of the boiler body for continuous heating, so that energy is used sufficiently, energy consumption of the boiler is reduced, and the energy-saving waste heat utilization boiler has higher a utility value.

Description

Energy-saving residual heat utilizes boiler

Technical field

The utility model belongs to boiler manufacturing technology field, is specifically related to a kind of energy-saving residual heat and utilizes boiler.

Background technology

Boiler is the rich and influential family who expends the energy, it is when providing convenience for people's lives, also expended a large amount of fuel, existing boiler, directly discharges by chimney after the flue gas in it circulates in fire tube, causes flue gas still very high in chimney outlet temperature, and this portion of energy just wastes and has lost, can be provided the today of building a conservation-minded society, and this type of boiler obviously can not adapt to the needs of form, is therefore necessary to improve.

Utility model content

The technical problem that the utility model solves: provide a kind of energy-saving residual heat to utilize boiler, energy-saving appliance is installed on the chimney top arranging outside boiler body, the inner water pipe of installing of energy-saving appliance, cold water first enters in water pipe from the feed pipe of energy-saving appliance, utilizes after fume afterheat preheating by outlet pipe again and enters in the water trapping layer of boiler body and continue heating.

The technical solution adopted in the utility model: energy-saving residual heat utilizes boiler, there is boiler body and the chimney that is placed in boiler body outside, the exhanst gas outlet of described boiler body is communicated with chimney by smoke exhaust pipe, described chimney top is provided with and can utilizes fume afterheat by the energy-saving appliance of preheating cold water, feed pipe is communicated with energy-saving appliance bottom, outlet pipe one end is communicated with energy-saving appliance top, and the outlet pipe other end is communicated with the water trapping layer in boiler body.

Wherein, described energy-saving appliance consists of body, horizontal water pipe and vertical water pipe, described body is sleeved on the excircle of chimney top, described horizontal water pipe is 90 degree through chimney and is distributed in body with vertical water pipe, and the water of described feed pipe enters horizontal water pipe and vertical water pipe enters in the water trapping layer in boiler body from outlet pipe after smoke pre-heating.

Further, described boiler body is provided with delivery port, atmosphere UNICOM mouth and sewage draining exit, on the smoke box assembly of boiler body, is provided with explosion proof door and condensate pipe.

The utility model compared with prior art makes full use of the waste heat of discharge flue gas by preheating cold water, and then flows into the interior continuation heating of water trapping layer of boiler body, makes full use of the energy, and reduction boiler energy consumption, has higher practical value.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

The specific embodiment

Below in conjunction with accompanying drawing 1, a kind of embodiment of the present utility model is described.

Energy-saving residual heat utilizes boiler, there is boiler body 1 and the chimney 2 that is placed in boiler body 1 outside, described boiler body 1 is provided with delivery port 10, atmosphere UNICOM mouth 11 and sewage draining exit 14, is provided with explosion proof door 15 and condensate pipe 13 on the smoke box assembly 12 of boiler body 1.The exhanst gas outlet of described boiler body 1 is communicated with chimney 2 by smoke exhaust pipe 3, described chimney 2 tops are provided with and can utilize fume afterheat by the energy-saving appliance of preheating cold water 4, feed pipe 5 is communicated with energy-saving appliance 4 bottoms, outlet pipe 6 one end are communicated with energy-saving appliance 4 tops, and outlet pipe 6 other ends are communicated with the water trapping layer in boiler body 1.Specifically, described energy-saving appliance 4 consists of body 7, horizontal water pipe 8 and vertical water pipe 9, described body 7 is sleeved on chimney 2 top excircles, described horizontal water pipe 8 is 90 degree through chimney 2 and is distributed in body 7 with vertical water pipe 9, and the water of described feed pipe 5 enters horizontal water pipe 80 and vertical water pipe 9 enters in the water trapping layer in boiler body 1 from outlet pipe 6 after smoke pre-heating.

Cold water enters horizontal water pipe 8 and vertical water pipe 9 after high-temperature flue gas preheating from feed pipe 5, by outlet pipe 6, enter and in the water interlayer of boiler body 1, continue heating, due to the water process preheating entering in boiler body 1 water interlayer, there is certain temperature, during again through boiler body 1 heating, take full advantage of the waste heat of flue gas, thus fuel saving, the utilization rate of raising fuel.

Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting the utility model practical range, and the equivalence of being done with content described in the utility model claim therefore all changes, within all should being included in the utility model claim scope.
