The utility model provides a scheme makes the high temperature fluid pipeline get into earlier the preliminary heat transfer of protection device, and then entering heat exchanger continuation cooling makes gas reach the technological requirement, the device simple and practical, with low costs, the income is high, use the back, can make production continuity, reliability improve, reduced maintenance personal's work load, improved the productivity, provide a sustainable development's profit growth space for the enterprise.
Description
Technical field
This utility model relates to high temperature fluid and processes, and is specifically related to a kind of high temperature fluid heat exchanger.
Background technology
In the Joining Technology of high temperature fluid pipeline and coil heat exchanger, it is generally adopted high temperature fluid inlet duct to be directly welded to connect with outer cover of heat exchanger body, this connected mode often results in high temperature fluid pipeline and damages with outer cover of heat exchanger connecting portion drawing crack, makes the cooling medium seepage being full of in heat exchanger.In order to terminate reaction process, the high-temperature gas of about 800 DEG C needs rapid cooling to less than 150 DEG C, if adopting the mode that is directly connected to, pipeline is with apparatus connecting unit position owing to temperature difference impact causes that connecting portion drawing crack is impaired frequently, and repair rate is high.Therefore the direct welding connecting mode that prior art provides can not resist the stress rupture that difference variation is brought.
Utility model content
The purpose of this utility model is the defect overcoming prior art, it is provided that a kind of high temperature fluid heat exchanger.
High temperature fluid described in the utility model refers mainly to the high-temperature gas of about 800 DEG C.
Specifically, this utility model provides a kind of high temperature fluid heat exchanger, including the high temperature fluid inlet tube being linked in sequence, coil heat exchanger and high temperature fluid outlet；The periphery parcel cooling protection set of described high temperature fluid inlet tube.
In order to realize the effect of cooling protection, described cooling protection set is the hollow structure that there is shell outside, and the inner space of this hollow structure is full of cooling medium.The top of described cooling protection set arranges riser mouth, it is simple to discharged by the cooling medium after thermal evaporation.Described riser mouth can be connected with cooling medium retracting device, it is simple to the recycling of cooling medium.
As a kind of preferred version, described cooling medium is cooling water；The top of described cooling protection set arranges steam riser mouth.
Described coil heat exchanger includes shell and is positioned at the coil of described enclosure.Described high temperature fluid inlet tube, coil and high temperature fluid outlet order successively is connected, to guarantee that high temperature fluid flows out from outlet through coil after entering from inlet tube.There is between described shell and coil certain space, in this space, be full of cooling medium.
The shell of described cooling protection set directly welds with the shell of described coil heat exchanger, it is possible to make the thermal stress of connecting portion decline, destructive reduction, it is ensured that equipment failure rate reduces, it is ensured that equipment long-term operation.
As a kind of preferred version of the present utility model, the cooling medium within described cooling protection set is connected with the cooling medium between described shell and coil, so that it is guaranteed that the thermal stress of connecting portion declines.
The scheme that this utility model provides makes high temperature fluid pipeline be introduced into the protection preliminary heat exchange of device, then enters back into heat exchanger continuation cooling and makes gas reach technological requirement；This device is simple and practical, and cost is low, and income is high；After using, it is possible to make continuous production, reliability improve, reduce maintainer workload, improve production capacity, provide the profit growth space of a sustainable development for enterprise.
Accompanying drawing explanation
Fig. 1 is a kind of hot-gas channel described in embodiment 1 and heat exchanger connecting portion protection device schematic diagram；Wherein, 1, high temperature fluid inlet tube, 2, cooling protection set, 3, steam riser mouth, 4, coil heat exchanger, 5, high temperature fluid outlet.
Detailed description of the invention
Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
Embodiment 1
Present embodiments provide a kind of high temperature fluid heat exchanger (as shown in Figure 1), including the high temperature fluid inlet tube 1 being linked in sequence, coil heat exchanger 4 and high temperature fluid outlet 5；
The periphery parcel cooling protection set 2 of described high temperature fluid inlet tube 1；The internal cooling water that is full of of described cooling protection set 2, the top of described cooling protection set 2 arranges steam riser mouth 3；
Described coil heat exchanger 4 includes shell and is positioned at the coil of described enclosure；Described high temperature fluid inlet tube, coil and high temperature fluid outlet order successively is connected；Cooling water it is full of between described shell and coil；
Described cooling protection set 2 directly welds with the shell of described coil heat exchanger 4；Cooling water within described cooling protection set 2 connects with the cooling aqueous phase between described shell and coil.
Embodiment of above is merely to illustrate this utility model; and be not limitation of the utility model; those of ordinary skill about technical field; when without departing from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all equivalent technical schemes fall within category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
