Description

Improved structure for collecting noncondensable gas of bulging heat transfer plate

Technical Field

The utility model belongs to the heat transfer device field, concretely relates to improvement structure is collected to bloated heat transfer plate noncondensable gas.

Background

The bulging heat transfer plate is a heat exchange plate with two channels at the inner side and the outer side, which is manufactured by welding and bulging 2 thin stainless steel plates;

in heat exchangers and evaporator equipment using a bulging heat transfer plate as a heat transfer element, heating steam is introduced into an inner cavity of the bulging heat transfer plate to exchange heat with liquid flowing through the outer surface of the bulging heat transfer plate, so that heat transfer and solution evaporation processes are realized. In the use, because heating steam inevitably contains a small amount of noncondensable gas, need discharge this part noncondensable gas bulging heat transfer plate, only set up the gas vent in the heat transfer plate tail end side of bloating in the current design of bulging heat transfer plate simply, this kind of structure is discharged noncondensable steam in a large number and is smugglied secretly out, has caused a large amount of energy extravagant. Meanwhile, the opposite position of the bulging heat transfer plate at the exhaust port generates a heat transfer dead zone, steam generates a short-circuit effect, and only a small amount of steam passes through the heat transfer dead zone, so that the heat transfer efficiency of the bulging heat transfer plate is influenced.

In view of the above-mentioned deficiencies, there is a need for an improved structure for collecting noncondensable gas of an intumescent heat transfer plate, which can reduce the steam entrainment during collecting the noncondensable gas, reduce the steam energy consumption, reduce the heat transfer dead zone, and improve the heat transfer efficiency of the intumescent heat transfer plate.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an improvement structure is collected to the noncondensable gas of bloated heat transfer plate, the reducible steam of collecting when noncondensable gas smugglies secretly, reduces steam energy resource consumption, reduces the heat transfer blind spot simultaneously, improves the heat transfer efficiency of bloated heat transfer plate.

The utility model provides a following technical scheme:

an improved structure for collecting noncondensable gas of a bulging heat transfer plate comprises a bulging heat transfer plate which is formed by welding and bulging two stainless steel plates and is provided with an inner channel and an outer channel, wherein the middle of the bulging heat transfer plate is provided with an inner channel; an S-shaped non-condensable gas channel is arranged at the tail part of the bulging heat transfer plate and in front of the non-condensable gas outlet; attaching two stainless steel plates by using a tool at a required position, and welding, thereby forming a noncondensable gas channel at the tail part of the bulging heat transfer plate, forcing the noncondensable gas to flow through a collecting channel, in the flowing process, steam carried in the noncondensable gas transfers heat to an outer cold fluid on the heat transfer surface of the bulging heat transfer plate, and the steam is condensed; the uncondensed noncondensable gas passes through the collecting channel and is discharged out of the swelling heat transfer plate. The structure obviously improves the non-condensable gas collecting efficiency of the expanded heat transfer plates, greatly reduces the steam entrainment when collecting the non-condensable gas and reduces the steam energy consumption; the method of forming the non-condensable gas channel by welding enables steam to pass through the originally designed heat exchange dead zone, avoids steam short circuit, reduces the heat exchange dead zone and increases the heat transfer efficiency of the equipment.

Preferably, the non-condensable gas channel may consist of several baffled channels.

Preferably, the non-condensable gas channel may be S-shaped, L-shaped or other shapes.

The utility model has the advantages that:

the improvement of the utility model can increase the staying time of the non-condensable gas in the internal channel, so that the steam carried by the non-condensable gas can be fully condensed, the steam carrying belt when the non-condensable gas is collected is reduced, and the steam energy consumption is reduced; meanwhile, as the baffle channel is added, the heat transfer dead zone of the bulging heat transfer plate is reduced, the short circuit of steam is avoided, and the heat transfer efficiency of the bulging heat transfer plate is increased.
