The utility model discloses a CO (Carbon Monoxide) converting device, which belongs to the field of ammonia synthesis equipment. The CO converting device structurally comprises a saturated hot water tower, a steam humidifying tank, a main heat exchanger, a converting furnace and a hot water heater, wherein the steam humidifying tank and the main heat exchanger are installed on a pipeline between the top output port of the saturated hot water tower and the top input port of the converting furnace; the hot water heater is installed on a pipeline between the bottom output port of the converting furnace and the bottom input port of the saturated hot water tower; and a water spraying humidifier is installed on a pipeline between the output port of the main heat exchanger and the input port at the lower part of the converting furnace. Compared with the prior art, the CO converting device disclosed by the utility model has the following characteristics that firstly, the load of the saturated hot water tower is alleviated, and the corrosion to the saturated hot water tower is reduced; secondly, the operation cost is lowered, and the working cost is reduced; and thirdly, the long-standing corrosion problem of a temperature adjusting water heater is solved, and the service life of the device is prolonged.
Description
Technical field
The utility model relates to ammonia synthesis unit field, specifically a kind of CO changing device.
Background technology
Through making great efforts for many years of China scientific worker, present CO conversion process has been obtained significant progress, be temperament water heater to be set reclaim heat in conversion gas with the more typical flow process of total lts technique of saturated hot-water tower in present medium and small synthetic ammonia installation, thereby improve temperature and the vapour content (referring to Fig. 1) of the semi-water gas of saturated section outlet of saturated hot-water tower.This is a kind of more traditional method that reclaims the transformation system energy.
The water temperature of advancing saturator is relevant with reaction pressure, hot water circulation amount, shift converter temperature out, reaction steam-to-gas ratio etc., is generally 130～140 ℃, and flow process saturated hot-water tower duty ratio as shown in Figure 1 is larger, and the saturator temperature out is high, usually has etching problem.Simultaneously due to dissolved in hot water semi-water gas carry into the materials such as grit, oxygen, hydrogen sulfide, dissolved the hot water pH value slant acidity of sour gas, can cause corrosion to the temperament water heater heat transfer tube, because the pipe wall pressure is higher than shell pressure, if seriously corroded can cause hot water to reveal, steam is transformed gas and carries into the shift converter latter end, so cause the water logging of shift converter latter end catalyzer, harden, inactivation.
Summary of the invention
Technical assignment of the present utility model is for above weak point, provides that a kind of production cost is low, the CO changing device of long service life.
The technical scheme that its technical problem that solves the utility model adopts is: this CO changing device comprises saturated hot-water tower, steam humidifying tank, main heat exchanger, shift converter and hot water heater, on the pipeline between the top delivery port of saturated hot-water tower and the input aperture, top of shift converter, steam humidifying tank and main heat exchanger is installed; On pipeline between the bottom delivery port of shift converter and the input aperture, bottom of saturated hot-water tower, hot water heater is installed; On pipeline between the input aperture of the delivery port of main heat exchanger and shift converter bottom, the work of water sprinkling for better material moisture device is installed.
On the hot water circulation pipeline of described saturated hot-water tower, hot water circulating pump is installed.
Compared to the prior art CO changing device of the present utility model has following characteristics:
1) reduced the saturated hot-water tower load, the corrosion that has alleviated saturated hot-water tower;
2) reduce working cost, reduced job costs;
3) solve the long-standing etching problem of temperament water heater, extended the work-ing life of device.

In figure: 1, saturated hot-water tower, 2, the steam humidifying tank, 3, main heat exchanger, 4, shift converter, 5, hot water heater, 6, hot water circulating pump, 7, temperament water heater, 8, the work of water sprinkling for better material moisture device.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
A kind of CO changing device of the present utility model, its structure comprises saturated hot-water tower 1, steam humidifying tank 2, main heat exchanger 3, shift converter 4 and hot water heater 5, on the hot water circulation pipeline of saturated hot-water tower 1, hot water circulating pump 6 is installed, on the pipeline between the top delivery port of saturated hot-water tower 1 and the input aperture, top of shift converter 4, steam humidifying tank 2 and main heat exchanger 3 is installed; On pipeline between the bottom delivery port of shift converter 4 and the input aperture, bottom of saturated hot-water tower 1, hot water heater 5 is installed; On pipeline between the input aperture of the delivery port of main heat exchanger 3 and shift converter 4 bottoms, work of water sprinkling for better material moisture device 8 is installed.
During work: the high-temperature gas that goes out 4 two sections of shift converters enters the work of water sprinkling for better material moisture device 8 that newly increases after main heat exchanger 3 coolings, further use the deaerated water humidifying cooling, then enter 4 three sections transformationreations of shift converter, high temperature shift gas is after hot water heater 5 and circulating hot water heat exchange, enter saturated hot-water tower 1 hot water section, the conversion gas after cooling is sent the battery limit (BL).Go out saturated hot-water tower 1 hot water section's hot water through hot water circulating pump 6 pressurizations, directly enter again saturated section of saturated hot-water tower 1 after hot water heater 5 temperature raisings, owing to having removed temperament water heater 7, the inflow temperature of saturated hot-water tower 1 decreases, general decline 6 ℃, the corrosion of saturated hot-water tower 1 is corresponding alleviating also.
A kind of its processing and fabricating of CO changing device of the present utility model is very simple and convenient, and shown in the by specification accompanying drawing, processing and fabricating gets final product.
Except the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
