Abstract
The invention relates to a cooling water technology of a gasification section quench ring, in particular to a cooling water process applied to a gasifier quench ring, which solves the problems of difficultly controlled program, large power consumption and insufficient adaptability of the existing cooling water technology of quench rings. The steps are as follows: water of a normal pressure cooling water tank enters a gasifier quench chamber inlet through a cooling water pump, and then cooling water from the quench chamber bottom is sent to the cooling water tank again to recycle. After the transformation of cooling water flow, the industrial application leads a gasifier to achieve simple operation, facilitated control and quick switch when baking, thus saving the power consumption, simplifying the process, effectively saving the equipment operation cost and greatly reducing the incidence of the accident.
Description
Technical field
The present invention relates to the water coolant technology of the chilling ring of a kind of methyl alcohol and synthetic ammonia gasification workshop section, be specially a kind of cooling water process that is applied to chilling ring of gasifying furnace.
Background technology
The cleaning of coal and efficient utilization are the great technical tasks in current China energy and environment protection field, also are one of gordian techniquies of Chinese national economy sustainable development.Gasification is the main path that primary energy source is converted into clean secondary energy, its product is fuel gas (coal gas), synthetic gas, reducing gas, hydrogen, carbon monoxide, and effective utilization of the various by-product energy that produces of how will gasifying is the key that reduces device running cost.Under the situation of present energy scarcity, how to reduce the energy loss in the gasification installation, become each large and medium-sized enterprise question of common concern of present home and abroad.
Domestic in recent years newly-built methyl alcohol and synthetic ammonia installation; in the baker process of vapourizing furnace; need carry out cooling protection to chilling ring; chilling ring cooling water process flow process generally adopts traditional process; as schematically shown in Figure 2; comprise a deoxygenator 11, high pressure ash water pump 10, washing tower 7, cold shock water pump 8, Venturi scrubber 6 etc., the characteristics of this flow process:
1 this flow process adopts the main output equipment of Quench water pump as the vapourizing furnace preheating water, and because of the power of Quench water pump is bigger, power of motor is 110KW, so energy consumption is higher.
2 these flow process control more complicated.Because set up earlier certain liquid level when driving in the synthesis gas washing tower, major part circulates by Venturi scrubber, has only the water coolant of a small part as chilling ring, so the energy consumption waste is bigger, and the control more complicated.
3, the control of washing tower liquid level is mainly regulated by high pressure ash water pump, the washing tower of several ordinary production supplies water because high pressure ash water pump also will be given in addition, cause the liquid level of each washing tower wayward, liquid level causes the chilling ring lack of water easily when low, damage chilling ring, may enter the conversion catalyst by syngas outlet when liquid level is high, influence back workshop section produces.
4, the draining of vapourizing furnace is mainly flow backwards by lock hopper circulating-pump outlet pipeline and is discharged, if the chilling ring water coolant increases, the vapourizing furnace liquid level will rise, and causes liquid level to rise to the combustion chamber when serious, damages refractory brick.
Summary of the invention
The difficult control of existing water coolant technical program, watt consumption are big in order to solve in the present invention, adaptability problem and a kind of cooling water process that is applied to chilling ring of gasifying furnace is provided widely inadequately.
The present invention is realized by following technical scheme, a kind of cooling water process that is applied to chilling ring of gasifying furnace, step is when the vapourizing furnace baker, the import that the water of normal pressure cooling trough is entered the shock chamber of vapourizing furnace by the preheating water pump, the water coolant that comes out from the bottom, shock chamber is sent into cooling trough again and is recycled then.
Vapourizing furnace and cooling trough form independent closed cycle by cooling-water pump, water coolant is set up the closed cycle of oneself separately during the vapourizing furnace baker, use lower-powered handling equipment, as long as can satisfy the requirement of cooling chilling ring institute water requirement, the main gravity flow that relies on water on regulating, strengthen nozzle diameter at the vapourizing furnace cooling water outlet, be convenient to water coolant and discharge vapourizing furnace, guaranteed that the liquid level of vapourizing furnace is in low liquid level.
Scheme of the present invention is not used the output equipment of original Quench water pump as water coolant, but directly water coolant is sent to the vapourizing furnace shock chamber with small-sized cooling-water pump, overcome former chilled water flow process energy consumption height, misoperation is big to the harm that system causes, the defective of the wayward grade of production operation is avoided unnecessary loss.Cooling water flow path when this kind scheme is fit to all vapourizing furnace bakers.
Generally speaking: the present invention has following characteristics: 1 program is easy to control.Because of flow process is simpler, only need set up certain liquid level in cooling trough just can realize recycling of water coolant before driving, so control convenient, succinct.2 energy consumptions are low.Because of the power of motor of Quench water pump is 110KW, and the power of motor of cooling-water pump is 30KW, but power saving 80KW so per hour.3 conserve water resources.The water coolant of this flow process enters cooling trough after by chilling ring when the vapourizing furnace baker, recycle, if the temperature height enters the buck tank by overflow port, the make up water as system reaches the reasonable resources utilization.4 vapourizing furnace liquid levels need not controlled.Because of the flow of preheating water pump is 25m
3/ h, this flow are easy to flow out from overflow port, enter the system cools tank and recycle, so need not control liquid level.
