Abstract
The utility model relates to a nitrogen heat exchange system for sintering vanadium-nitrogen alloy. The heat exchange system for sintering vanadium-nitrogen alloy is characterized by comprising a liquid nitrogen storage tank (1), wherein the liquid outlet of the liquid nitrogen storage tank (1) is connected with a first heat exchange tube (2), the first heat exchange tube (2) is divided into two branches which are respectively connected with a second heat exchange tube (3) and a third heat exchange tube (4), and the gas outlets of the second heat exchange tube (3) and the third heat exchange tube (4) are integrated into a whole to be connected with a buffer tank (5). According to the heat exchange system for sintering vanadium-nitrogen alloy, disclosed by the utility model, as the second heat exchange tube and the third heat exchange tube which are connected in parallel are additionally arranged, the nitrogen output from the first heat exchange tube can be fully heated, only less heat can be absorbed when the nitrogen enters a tunnel furnace, and thus the energy consumption during the sintering can be reduced.
Description
Technical field
The utility model relates to a kind of nitrogen heat-exchange system that is used for the sintering VN alloy.
Background technology
VN alloy need feed nitrogen during sintering in tunnel in tunnel, to guarantee that outside air can not get in the tunnel, avoid having an accident, therefore just with sending in the tunnel through heat-exchange system in the liquid nitrogen storage tank.Yet nitrogen heat-exchange system in the past just leads to the liquid nitrogen in the liquid nitrogen storage tank in the tunnel after through a heat transfer tube.Yet the nitrogen that feeds does not so rise to enough temperature, feeds in the pyritous tunnel to absorb heat, reach that the sintering temperature of VN alloy is just extra to have improved energy consumption.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of nitrogen that makes fully to heat up, and has reduced the nitrogen heat-exchange system that is used for the sintering VN alloy of tunnel energy consumption.
The purpose of the utility model is achieved in that
The utility model is used for the nitrogen heat-exchange system of sintering VN alloy; Comprise liquid nitrogen storage tank; The liquid outlet of said liquid nitrogen storage tank links to each other with first heat transfer tube; Said first heat transfer tube is divided into two-way and links to each other with the 3rd heat transfer tube with second heat transfer tube respectively, and the escape pipe of said second heat transfer tube and the 3rd heat transfer tube converges into one the tunnel and links to each other with surge tank.
Compared with prior art, the beneficial effect of the utility model is:
This extra second heat transfer tube and the 3rd heat transfer tubes that added two parallel connection settings of nitrogen heat-exchange system that are used for the sintering VN alloy; Can the nitrogen that first heat transfer tube comes out fully be heated up; Nitrogen gets into just only to be needed in the tunnel to absorb less heat, has so just lowered the required energy consumption of sintering.
Description of drawings
Fig. 1 is used for the structural representation of the nitrogen heat-exchange system of sintering VN alloy for the utility model.
Wherein: liquid nitrogen storage tank 1, first heat transfer tube 2, second heat transfer tube 3, the 3rd heat transfer tube 4, nitrogen buffer tank 5, tunnel 6.
Embodiment
Referring to Fig. 1; The utility model relates to a kind of nitrogen heat-exchange system that is used for the sintering VN alloy; Comprise liquid nitrogen storage tank 1, the liquid outlet of said liquid nitrogen storage tank 1 links to each other with first heat transfer tube 2, and said first heat transfer tube 2 is divided into two-way and links to each other with the 3rd heat transfer tube 4 with second heat transfer tube 3 respectively; The escape pipe of said second heat transfer tube 3 and the 3rd heat transfer tube 4 converges into one the tunnel and links to each other with surge tank 5, and the escape pipe of said surge tank 5 links to each other with the inlet mouth of tunnel 6.
Claims (1)
1. nitrogen heat-exchange system that is used for the sintering VN alloy; It is characterized in that: it comprises liquid nitrogen storage tank (1); The liquid outlet of said liquid nitrogen storage tank (1) links to each other with first heat transfer tube (2); Said first heat transfer tube (2) is divided into two-way and links to each other with the 3rd heat transfer tube (4) with second heat transfer tube (3) respectively, and the escape pipe of said second heat transfer tube (3) and the 3rd heat transfer tube (4) converges into one the tunnel and links to each other with surge tank (5).
