Description

A kind of boiler heating system pressure relief device for avoiding thermal loss

Technical field

The utility model is related to boiler technology field, more particularly to a kind of boiler pressure relief device.

Background technology

Boiler heating is currently used most ways of heating, by fuel combustion heating boiler, is released by recirculated water For thermal discharge to using area, comparatively principle is fairly simple for this heating system, and is not also expensive in fuel energy When be both economical, but substantial amounts of unstability is still remained while heating boiler, usually prevented in boiler Gas pressure is excessive to generate explosion, relief valve can be set above boiler, and in this case, relief valve by stretching upwards at the top of boiler Go out, be directly connected with air, using the boiler pressure relief device of similar structures, big calorimetric is also contained by the steam of pressure release release Amount, these steam endlessly can be discharged outwards, and heat-energy losses are more, can waste mass energy, so needing to improve this The conventional boiler pressure relief device of waste of resource, the heat recovery and utilization that will be discharged during pressure release in steam, can greatly reduce the energy Waste.

Utility model content

By analyzing the deficiencies in the prior art, the utility model is intended to provide a kind of boiler heating system for avoiding thermal loss System pressure relief device to reduce boiler heat-energy loss, while ensures the effect of safety relief.

To achieve these goals, the technical solution that the utility model is taken is as follows：A kind of boiler for avoiding thermal loss Heating system pressure relief device, including boiler room, hot duct, feedwater piping, the hot duct is connected under boiler room side Side, the feedwater piping are connected to above boiler room side, and the boiler room top is provided with relief pipeline, the relief pipeline It connects in boiler room and is additionally provided with separate space with outdoor, the boiler room internal upper part, be to add below boiler room to contain below separate space The heating cabinet of hot water, the separate space are not attached to lead to the heating cabinet below boiler room, and the relief pipeline is directly protruding into heating It in storehouse, and passes through, then is in communication with the outside from separate space, so inherently pass through when the steam in heating cabinet is discharged from relief pipeline Separate space, and separate space is relatively low with respect to temperature in heating cabinet, and steam can be promoted to condense and be back in heating cabinet, reduces the damage of heat It loses.

Further, filled that boiling point is higher than water and nonflammable liquid in the separate space that the boiler room internal upper part is set, Such as acetic acid（Boiling point 117.9oC）, since the boiling point of liquid in separate space is more than water, then it never seethes with excitement, and separate space can be located always In safe condition, and separate space, not by directly heating, temperature is relatively low, and the steam in heating cabinet is passed through by relief pipeline When crossing separate space, the relatively low liquid of relative temperature can promote steam liquefied to be back to again in heating cabinet in separate space, reduce heat Loss, while the heat of steam liquefied release can be by the liquid absorption in separate space, and separate space is equally in boiler room, in separate space Heat be eventually slowly transferred in heating cabinet, be further reduced thermal loss.

Further, the surrounding of the separate space extends downwards to the both sides of heating cabinet, forms the encirclement to heating cabinet top Body, advantageous effect is the capacity that can increase separate space, while improves the contact surface of separate space and heating cabinet, accelerates heat transfer.

Further, the relief pipeline is pierced by by being provided with one end coiling during separate space, then from boiler room top, with External world's connection sets the effect of coiling to be to improve relief pipeline and the contact every intracavity liquid, while increases relief pipeline Length promotes the steam liquefied reflux from this process, is further reduced thermal loss.

Description of the drawings

It, below will be to embodiment and description of the prior art in order to illustrate more clearly of the utility model embodiment technical solution Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model Some embodiments, for those of ordinary skill in the art, without creative efforts, can also be according to this A little attached drawings obtain other attached drawings.

Fig. 1 is a kind of structure diagram of embodiment of the utility model.

Fig. 2 is the structure diagram that the utility model improves embodiment.

Specific embodiment

The utility model provides a kind of boiler heating system pressure relief device for avoiding thermal loss, as shown in Figure 1, including pot Furnace chamber 1, hot duct 2, feedwater piping 3, the hot duct 2 are connected to below 1 side of boiler room, the feedwater piping 3 It is connected to above 1 side of boiler room, 1 top of boiler room is provided with relief pipeline 4, and the relief pipeline 4 connects boiler room 1 Indoor and outdoor, top is additionally provided with separate space 5 in the boiler room Room 1, and 5 lower section of separate space is that 1 lower section of boiler room is to contain heating The heating cabinet 6 of water, the separate space 5 and the heating cabinet 6 of 1 lower section of boiler room are not attached to lead to, and the relief pipeline 4, which is directly protruding into, to be added It in hot storehouse 6, and passes through, then is in communication with the outside from separate space 5, it must so when the steam in heating cabinet 6 is discharged from relief pipeline 4 Separate space 5 can be passed through, and temperature is relatively low in opposite heating cabinet 6 in separate space 5, and steam can be promoted to condense and be back in heating cabinet 6, Reduce the loss of heat.

Further, filled that boiling point is higher than water and nonflammable liquid in the separate space 5 that 1 internal upper part of boiler room is set Body, such as acetic acid（Boiling point 117.9oC）, since the boiling point of liquid in separate space 5 is more than water, then it never seethes with excitement, the meeting of separate space 5 one It is straight to be in safe condition, and separate space 5 is that by directly heating, temperature is not relatively low, and the steam in heating cabinet 6 passes through pressure release When pipeline 4 is by separate space 5, the relatively low liquid of relative temperature can promote steam liquefied to be back to again in heating cabinet 6 in separate space 5, The loss of heat is reduced, while the heat of steam liquefied release can be by the liquid absorption in separate space 5, and separate space 5 is equally in pot In furnace chamber 1, the heat in separate space 5 is eventually slowly transferred in heating cabinet 6, is further reduced thermal loss.

Further, the surrounding of the separate space 5 extends downwards to the both sides of heating cabinet 6, is formed and surrounds 6 top of heating cabinet Enclosure body 51 as shown in Fig. 2, advantageous effect is the capacity that can increase separate space 5, while improves connecing for separate space 5 and heating cabinet 6 Contacting surface accelerates heat transfer.

Further, the relief pipeline 4 is coiling 41 by being provided with one section at separate space 5, as shown in Fig. 2, again from pot 1 top of furnace chamber is pierced by, and is in communication with the outside, and the effect of coiling is set to be to improve the contact with liquid in separate space 5 of relief pipeline 4, Increase the length of relief pipeline 4 simultaneously, promote the steam liquefied reflux from this process, be further reduced thermal loss.
