Description

The steam boiler heat exchanger

Technical field

The utility model relates to a kind of steam boiler heat exchanger, is used to reclaim and utilizes a large amount of superfluous water steam that steam boiler produced when producing and the latent heat of water vapour, belongs to the energy saver of steam boiler.

Background technology

At present, be widely used in the steam boiler of occasions such as clothes ironing, disinfecting, food boiling, no matter be the electrical heating type steam boiler, or with coal or with the steam boiler of gas, oil heating, in actual production process, all there is following defective: at first, contain a large amount of water vapours in the useless tail gas of boiler emission, this part water vapour is directly emitted, and not only can cause the waste of great lot of water resources, but also the environment around can influencing is unfavorable for environmental protection; Secondly, after a large amount of water vapours is evaporated, need in boiler furnace, replenish the water source in time, when replenishing the water source, also need the water at low temperature in the body of heater is constantly heated, not only cause the significant wastage of the energy, and inaction ground has increased user's use cost; Again, because the water source that replenishes is a cold water, can cause the fluctuation of stove internal gas pressure in the time of in cold water enters body of heater, cause the pressure of steam when producing on the low side, influence is worked normally.

Summary of the invention

The purpose of this utility model is that a kind of environmental protection, energy-conservation, steam boiler heat exchanger efficiently will be provided, it can not only reclaim a large amount of water vapour in the useless tail gas, can also utilize the high temperature latent heat of water vapour that the water source that will enter in the stove is preheated, to reduce the fluctuation of stove internal gas pressure, that guarantees to produce normally carries out.

The purpose of this utility model reaches like this, a kind of steam boiler heat exchanger, it comprises staving 1 and coil pipe 2, at the bottom of the top of described staving 1 is provided with bung 11, bottom and is provided with barrel 12, on bung 11, be equipped with and be used for the delivery port 111 that is connected with the boiler feed water mouth, be used for the water inlet 121 that is connected with the water source being equipped with on 12 at the bottom of the bucket; Described coil pipe 2 places the die cavity of staving 1, is formed with the gas outlet 22 that is used for the air inlet 21 that is connected with the useless exhaust pipe of boiler and is used for opposing steam flow to water source in the pipe is gone on it respectively.

The utility model is provided with safety valve 112 on described bung 11.

Coil pipe 2 described in the utility model is crooked spirality.

Coil pipe 2 described in the utility model is crooked S shape.

Coil pipe 2 described in the utility model takes the shape of the letter U.

Bung 11 described in the utility model forms in the top of staving 1 integratedly.

Be fixed on to bung 11 splits described in the utility model the top of staving 1.

The bucket described in the utility model end 12, form in the bottom of staving 1 integratedly.

Be fixed on to the bucket described in the utility model ends 12 split the bottom of staving 1.

The utility model is installed with one barrel of seat 3 below the described bucket end 12.

The utility model is because after adopting said structure, one of advantage that has, with boiler outwards a large amount of water vapours in the useless tail gas of discharging after coil pipe 2 condensations, become water, this water is back in the pond of watering at last again, water-saving not only, and be beneficial to environmental protection, through facts have proved, compared with the prior art water consumption can save 60-70%; Two, since the pond in the water source when flowing through the die cavity of staving 1, the latent heat that utilizes water vapour is heat transferred coil pipe 2, by coil pipe 2 heat is discharged water source to the staving 1 of flowing through again, therefore the water source has been the condition of high temperature before entering boiler, can save the electricity consumption of boiler so effectively or with coal, gas, the wet goods energy, through facts have proved, compared with the prior art the energy can be saved about 30%; Three because the water source that enters in the boiler has been the condition of high temperature, thus little to the influence of fluctuations of stove internal gas pressure, help normal work.

Description of drawings

Accompanying drawing is an example structure sketch of the present utility model.

Among the figure: 1. at the bottom of the staving, 11. bungs, 111. delivery ports, 112. safety valves, 12. barrels, 121. water inlets; 2. coil pipe, 21. air inlets, 22. gas outlets; 3. bucket seat.

The specific embodiment

By the description of applicant, will help to understand the utility model more, but embodiment should not be considered as the restriction to some extent to the utility model scheme to embodiment.

Please refer to accompanying drawing, the utility model heat exchanger comprises staving 1 and coil pipe 2.At the bottom of the top of staving 1 is provided with bung 11, bottom and is provided with barrel 12, wherein bung 11 both can form with staving 1 integral production, also can fix by securing member again behind both split productions, delivery port 111 is installed on bung 11, delivery port 111 is connected with the water inlet of steam boiler by pipeline, for explosion-proof, a safety valve 112 can be installed on bung 11 simultaneously; Bucket both can form with staving 1 integral production at the end 12, also can fix by securing member behind both split productions again, water inlet 121 had been installed on 12 at the bottom of the bucket, water inlet 121 is connected with the water pump of watering by pipeline, simultaneously, for easy for installation, also be connected with one barrel of seat 3 on 12 at the bottom of the bucket.Coil pipe 2 twist or S shape or U-shaped or other Any shape place the die cavity of staving 1, its end, two ends is stretched out outside the staving 1 respectively and is formed with air inlet 21 and gas outlet 22, wherein air inlet 21 is connected with the useless exhaust pipe of steam boiler by pipeline, and introduce in the pond of watering by pipeline gas outlet 22.

The utility model is to come work like this: at first, the useless tail gas of the high temperature that steam boiler produces when producing enters the coil pipe 2 that is arranged in staving 1 die cavity by the air inlet 21 of coil pipe 2 by the road, at this moment the water vapour in the useless tail gas of high temperature is on the one hand with heat transferred coil pipe 2, on the other hand through the condensation of coil pipe 2, flow out by 22 places, gas outlet of coil pipe 2 behind the water of water vapour liquefy shape in the pipe and be back in the pond of watering, thereby realized the recycling of water resource.Meanwhile, be arranged in the pond as the water of watering under the effect of water pump power by bucket at the bottom of water inlet 121 places on 12 enter staving 1, under the heat effect of coil pipe 2, gradually become high-temperature-hot-water by cold water, the hot water that flows out from the delivery port 111 of bung 11 is entered in the boiler furnace by the water inlet of steam boiler by the road like this, finishes a circulation.Because the water that enters in the boiler furnace has become high-temperature-hot-water, can not only save the energy, and can reduce the fluctuation of boiler furnace internal gas pressure, that guarantees to produce normally carries out.
