Description
Technical field
The utility model relates to a kind of synthetic ammonia power-saving technology, relates in particular to a kind of conversion thermal water utilization energy conserving system.
Background technology
In the Chemical Manufacture Study on energy saving for many years; Various synthetic ammonia power-saving technologies have obtained application aborning, have obtained good economic benefits and social benefit, in the Chemical Manufacture enterprise of coal as raw material; The technology of various energy-saving and emission-reduction is all in continuous application; The utilization of waste heat overbottom pressure has caused the extensive concern of enterprise, through energy saving retrofit technology, has practiced thrift the energy widely.Synthetic ammonia changes low the change and full low temperature shift process in the general employing of operation, the reaction gas heat is also utilized, but traditional heat energy utilization is mainly provided by the reaction heat of conversion; Do not relate to other operation; And aging owing to the conversion catalyst in the reality production, heat of reaction is difficult to keep, and is to guarantee ordinary production; Usually need to strengthen steam consumption and maintain, caused steam loss big.
The utility model content
For solving the problems of the technologies described above, the utility model patent is carried a kind of conversion thermal water utilization energy conserving system that does not increase steam consumption.
The technical scheme of the utility model patent is: a kind of conversion thermal water utilization energy conserving system; Comprise saturator, conversion hot-water tower, hot water pump, one section thermosistor and two sections thermosistors; The conversion hot-water tower is connected respectively through the hot water inlet of hot water pump with one section thermosistor and two sections thermosistors; The hot water outlet of one section thermosistor and two sections thermosistors is connected with the hot water inlet of saturator; The hot water outlet of saturator is connected with the conversion hot-water tower, comprises that also one inhales outer cooler, and the hot water outlet of the outer cooler of a suction is communicated with the hot water inlet of conversion hot-water tower.Hot water in the conversion hot-water tower improves temperature after getting into one section thermosistor and two sections thermosistors, gets back to hot-water tower after getting into saturator and semi-water gas fully contacting, and forms circulation, and one inhale the hot water entering hot-water tower of outer cooler, is used for the heat of supplemental heat water tower.It is aging to have solved catalyst, the unbalanced problem of transformation system heat that causes.The saturation ratio of semi-water gas increases in this process.
Said conversion thermal water utilization energy conserving system also comprises deoxygenation water tank and hot water tank, and the import of deoxygenation water tank is connected with the outlet of the arm of hot water pump, and the outlet of deoxygenation water tank is connected with the hot water tank import.Unnecessary hot water gets into hot water tank from hot water pump through the deoxygenation water tank.The deoxygenation water tank is removed the oxygen in the hot water, and hot water tank stores unnecessary hot water.Hot water tank can be other operation hot water is provided.
Between the outlet of the outer cooler of a said suction and the import circulation line is set, variable valve is set on the circulation line.Circulation line capable of using improved the temperature of the hot water that gets into the conversion hot-water tower when cooler outlet hot water temperature was not enough outside inhaling.
On said conversion hot-water tower and the saturator self-adjusting valve is set.Self-adjusting valve is used for the liquid level and the water yield of control change hot-water tower and saturator.
Owing to adopt one to inhale the additional not enough phenomenon of conversion heat of hot soft water that outer cooler comes out, guarantee the saturation ratio of semi-water gas in the saturator, hot water more than needed can send the deoxygenation of deoxygenation water tank, send hot water tank to store and buffering, for other operations provide hot water.So just can practice thrift steam, reach the minimizing energy consumption, improve the purpose of business economic benefit.
Description of drawings
Fig. 1 is the structural representation of the conversion thermal water utilization energy conserving system among the embodiment.
Embodiment
Be elaborated below in conjunction with the conversion thermal water utilization energy conserving system of accompanying drawing to the utility model.
Embodiment
Conversion thermal water utilization energy conserving system comprises that one inhales outer cooler 1, saturator 2, conversion hot-water tower 3, hot water pump 4, one section thermosistor 5, two sections thermosistors 6, deoxygenation water tank 7 and hot water tanks 8; Conversion hot-water tower 3 is connected with the hot water inlet of one section thermosistor 5 and two sections thermosistors 6 through hot water pump 4; The hot water outlet of one section thermosistor 5 and two sections thermosistors 6 is connected with the hot water inlet of saturator 2; The hot water outlet of saturator 2 is connected with conversion hot-water tower 3, and the hot water outlet of the outer cooler 1 of a suction is communicated with the hot water inlet of conversion hot-water tower 3.Deoxygenation water tank 7 is connected with hot water pump 8, and hot water tank 8 is connected with deoxygenation water tank 7, and unnecessary hot water gets into hot water tank 8 from hot water pump 4 through deoxygenation water tank 7.Deoxygenation water tank 7 is removed the oxygen in the hot water, and hot water tank 8 stores unnecessary hot water.As shown in Figure 1, the flow direction of hot water is shown in arrow.
Be provided with circulation line 9 between the import of the outer cooler 1 of one suction and the outlet, circulation line 9 is provided with valve 10.
On conversion hot-water tower 3 and the saturator 2 self-adjusting valve is set.Self-adjusting valve is used for the liquid level and the water yield of control change hot-water tower and saturator.
The operational process of conversion thermal water utilization energy conserving system is following:
1, hot water replenishes
Cold soft water send conversion hot-water tower 3 to replenish hot water outside urea one is inhaled after cooler 1 heat exchange, this portion of hot water temp is higher than the hot water temperature in the following hot water circulation.
As circulation line 9 temperature raisings of the outer cooler 1 of the hot water temperature who gets into conversion hot-water tower 3 suction capable of using inadequately.
2, the circulation of hot water.
After saturator 2 hot water get into hot-water tower 3, send one section thermosistor 5, two sections thermosistors 6 to reduce the reaction gas temperature respectively through hot water pump 4, improve the hot water temperature, the hot water after the heat exchange send saturator 2 fully to contact with semi-water gas, the saturation ratio of raising semi-water gas.Wherein one section thermosistor 5 is middle change reaction gas and the indirect counter current contact of hot water, advances the low inlet gas temperature that becomes of conversion to reduce, and two sections thermosistors 6 are low reaction gas and indirect counter current contact of hot water of becoming, and advances the low Outlet Gas Temperature that becomes of conversion to reduce.
3, hot water more than needed sends outside.
Because above-mentioned hot water circulation cooler 1 outside inhales has replenished part hot water; The system hot water amount of causing has more than needed; Hot water more than needed flows to hot water tank 8 again and makes hot-water storage and buffering, for other operation provides hot water through the oxygen that hot water pump 4 arms send deoxygenation water tank 7 to remove in anhydrating.
