The utility model relates to a synthetic reaction heat steam generator which utilizes synthetic ammonia or other reaction heat to generate superheated steam. The middle part of an outer casing 1 is provided with a high pressure technology chamber 4 composed of a first, a second and a third chambers, and a U-shaped tube bundle 9 at the upper part, and a U-shaped tube bundle 10 at the lower part are arranged on tube plates 2, 3 at both sides of the outer casing. The tube bundle 9 is communicate with the first and the second chambers, and the tube bundle 10 is communicate with the second and the third chambers. The first chamber is provided with an inlet for reaction heat gas, and the third chamber is provided with an outlet for cold gas. The tube bundle 9 is positioned in a spacing ring 11. A superheated steam chamber 12 is provided with an outlet, and a saturated steam chamber 15 is provided with a water inlet 14. A synthesizing tower, a heat recovery steam generator and a saturated steam superheated device are connected into a whole by the utility model to form triad equipment, so that place occupation of the equipment is reduced, connected pipelines are reduced, heat loss is reduced, high-pressure pipelines made of special materials are saved, and reaction heat is effectively utilized.

Description

The synthetic reaction hot steam generator

Technical field

The utility model relates to and a kind ofly is used for that chemical reaction heat is many, reaction back gas temperature is high and reclaims the equipment that heat produces steam.

Background technology

In the existing production of synthetic ammonia, reaction heat fails to make full use of, and the steam generator that reclaims reaction heat is a discrete device, not only will take production site, and itself and the connecting pipe of synthetic tower bigger heat loss in addition.

The utility model content

The technical problems to be solved in the utility model is, defective at the prior art existence, design a kind of synthetic reaction hot steam generator, it can fuse synthetic tower, heat recovery steam generator, saturated vapor superheater and reduce occupation area of equipment, and reduce connecting pipe and heat loss, with reduce production costs, energy savings.

Technical solution of the present utility model is, it is the cylindrical housing of end socket that described synthetic reaction hot steam generator has two, its design feature is, this cylindrical housing middle part is separated out the high-pressure process chamber by two tube sheets that radially are provided with, described high-pressure process chamber is divided into the I chamber by two dividing plates that axially are provided with again, the II chamber, the III chamber, wherein the I chamber is provided with reaction hot air intake and the III chamber is provided with the reaction cold air outlet, the two ends that the upper outside of both sides, described high-pressure process chamber tube sheet is equipped with top U type tube bank and the tube bank of described top U type respectively are communicated with I chamber and II chamber respectively, bottom U type tube bank is housed respectively in the outside, bottom of both sides, described high-pressure process chamber tube sheet and described bottom U type tube bank two ends are communicated with II chamber and III chamber respectively, it is indoor that the U type tube bank of described top is positioned at the superheated steam that is separated out with space ring, some passages distribute on the space ring, described superheater chamber is provided with the superheated steam outlet, and U type tube bank in described bottom is arranged in the saturated chamber that is provided with water inlet.

Below make and further specifying.

Referring to Fig. 1, it is the cylindrical housing 1 of end socket that the utility model has two, its design feature is, this cylindrical housing 1 middle part is by two tube sheets 2 that radially are provided with, 3 are separated out high-pressure process chamber 4, as shown in Figure 3, described high-pressure process chamber 4 is again by two dividing plates 5 that axially are provided with, 6 are divided into the I chamber, the II chamber, the III chamber, wherein the I chamber is provided with reaction hot air intake 7 and III chamber and is provided with reaction cold air outlet 8, described high-pressure process chamber 4 both sides tube sheets 2, the two ends that 3 upper outside is equipped with top U type tube bank 9 and described top U type tube bank 9 respectively are communicated with I chamber and II chamber respectively, described high-pressure process chamber 4 both sides tube sheets 2, bottom U type tube bank 10 is housed respectively in 3 the outside, bottom and described bottom U type is restrained 10 two ends respectively with II chamber and the connection of III chamber, described top U type tube bank 9 is positioned at the superheater chamber 12 that is separated out with space ring 11, some passages distribute on the space ring 11, described superheater chamber 12 is provided with superheated steam outlet 13, and described bottom U type tube bank 10 is arranged in the saturated chamber 15 that is provided with water inlet 14.

The design principle of the present utility model and the course of work are (referring to Fig. 1), reaction hot gas enters I chamber the high-pressure process chamber 4 from reaction hot air intake 7, enter two groups of top U type tube banks 9 that are arranged in its left and right sides then, the other end by described top U type tube bank 9 enters the II chamber again, then an end of the bottom U type tube bank 10 through being communicated with the II chamber advances in this tube bank again, enter the III chamber by the other end of described bottom U type tube bank 10 again again, send from reaction cold air outlet 8 at last; Feedwater is sent into the saturated chamber 15 from water inlet 14, is heated into saturated vapor by bottom U type tube bank 10; The saturated vapor that has water droplet rise run into space ring 11 after, separated the getting off of water droplet and saturated vapor enter in the superheater chamber 12 by the passage of space ring 11, further be heated into the superheated steam of 3.5-5.5MPa by top U type tube bank 9, cause the external steam pipe network from superheated steam outlet 13.
