Description
Technical field
This utility model is related to a kind of synthesis ammonia plug-in type waste heat boiler of technical field of petrochemical industry.
Background technology
Waste heat boiler is the equipment using industrial exhaust heat next life producing steam or hot water, in coal gas chemical industry, synthesis ammonia work
The chemical technology fields such as industry, ethylene, sulphuric acid, nitric acid are extensively applied.With the development of industrial technology, one is occurred in that to waste heat boiler
A little high temperature, high pressure, the technological requirements of high flow rate, therefore the requirement to waste heat boiler is also more and more higher；Therefore plug-in type used heat
Boiler is occurred in that.Plug-in type waste heat boiler is suitable for big gas production, and higher steam pressure and heat-carrying agent are that High Temperature High Pressure is high
The operating condition of flow.Its advantage is the elongation that the reason for needing not compensate for because of the temperature difference is caused, and its own has freely stretches,
Heating surface heat exchange is uniform, while having simple structure, convenient to install and maintain etc..The current plug-in type in technical field of petrochemical industry
Waste heat boiler is broadly divided into single tube plug-in type, tube bank plug-in type and is inverted plug-in type etc..Can release substantial amounts of anti-when ammonia is synthesized
Should be hot, reacted high temperature, gases at high pressure are introduced into waste heat boiler from synthetic tower, waste heat therein is reclaimed, steam is produced, as
Power and process steam, so as to reduce the purpose of production cost.
The content of the invention
This utility model purpose is to improve the utilization rate that heat is released during ammonia synthesis, there is provided a kind of synthesis ammonia insertion
Formula waste heat boiler, it is convenient to use, it is easy to maintenance simple, it is improved heat exchange efficiency.
The technical scheme adopted by this utility model is：
A kind of synthesis ammonia plug-in type waste heat boiler of this utility model, mainly by housing, air water outlet, gas outlet, gear
Plate, heat-resistant lining, wastewater outlet, rectangular gas distributor, gas access, trocar sheath, inner sleeve, large tubesheet, air water case, water inlet
Case, water inlet and rectangle shower nozzle composition, it is characterised in that：The housing upper is provided with water inlet, inlet water tank, air water case and air water
Outlet；Middle part is provided with inner sleeve, gas outlet, trocar sheath and baffle plate；Bottom is provided with gas access, rectangular gas distributor and gives up
Water out；Large tubesheet is connected with trocar sheath, for fixed jacket pipe；Heat-resistant lining is provided with the inside of housing, is made in housing
Heat is not lost totally.Baffle plate is designed using S-shaped in housing, makes hot-air from along S-shaped flowing increase contact area；
Inner sleeve is located at the inside of trocar sheath, and water flows to trocar sheath from inner sleeve；Rectangular gas distributor is designed using rectangular, can be made
Hot gas mean allocation after rectangular gas distributor.
Advantage of the present utility model：It is convenient to use, it is not necessary to the relative elongation that compensation is produced because of the temperature difference, can be effective
Raising heat transfer effect.
Description of the drawings

Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described further.
As shown in figure 1, a kind of synthesis ammonia plug-in type waste heat boiler of this utility model, mainly by housing 1, air water outlet 2,
Gas outlet 3, baffle plate 4, heat-resistant lining 5, wastewater outlet 6, rectangular gas distributor 7, gas access 8, trocar sheath 9, inner sleeve
10th, large tubesheet 11, air water case 12, inlet water tank 13, water inlet 14 and rectangle shower nozzle 15 are constituted.1 top of the housing is provided with into water
Mouth 14, inlet water tank 13,12 gentle water out 2 of air water case；Middle part is provided with inner sleeve 10, gas outlet 3, trocar sheath 9 and baffle plate 4；
Bottom is provided with gas access 8, rectangular gas distributor 7 and wastewater outlet 6.
As shown in Figure 1 and Figure 2, specific heat transfer process is：Water enters housing 1 from water inlet 14, after rectangle shower nozzle 15
Average is allocated in inlet water tank 13, and the water in inlet water tank 13 passes through inner sleeve 10 toward downstream in trocar sheath 9, while high temperature
Gas is entered in housing 1 from gas access 8, is flowed out and is up flowed from rectangular gas distributor 7, S-shaped up along baffle plate 4
Motion, is exchanged heat with trocar sheath 9 while motion, and the water in trocar sheath 9 constantly evaporates and becomes air-water mixture, from lower
On flow out from the upper port of trocar sheath 9, in air water case 12, flow out from air water outlet 2.High-temperature gas after heat exchange
Decline is become to flow out from air water outlet 2 after cryogenic gas by temperature；If waste water is produced during heat exchange, can go out from waste water
Mouth 6 is discharged, and as high-temperature gas is constantly entered from gas access 8, is constantly exchanged heat, it will have increasing air water
Produce.
