Description
Technical field
The utility model belongs to coal water slurry gasification technical field, and in particular to the anti-clogging in a kind of raw gas cooling procedure
Device.
Background technology
After raw gas is by washing, dedusting, cooling, raw gas is set to be changed into temperature：37 DEG C, pressure：2.84Mpa clean coal
Gas, then it is sent to purifier.By the material such as institute's band tar, oil, phenol, ammonia, dirt is more in raw gas, raw gas is cooled down in coal gas
Device is after cleaning dust cools, when entering final cooler, because temperature is relatively low（37-85℃）, the ammonia in raw gas
Reacted with CO2 and generate ammonium hydrogen carbonate crystal, long-play can make depositing crystalline in final cooler tube side, form resistance
Power, on the one hand influence final cooler heat transfer effect, on the other hand make it that raw gas manifold pressure is higher, gasification furnace is difficult to high negative
Lotus runs.Purified gas after cleaning dust simultaneously, due to ammonia salt therein rapid crystallization at low ambient temperatures, causes clean coal
Gas outlet line inwall is crystallized, and pipeline caliber is diminished, system is built the pressure.Due to the limitation of equipment Design cooling load so that thick
Coal gas washs incomplete before final cooler is entered, and causes heat exchanger to block, and influence operating load and cycle, runs about 2 months
Left and right must be dredged to final cooler and gas exit pipeline, be cleared up, service work, and parking maintenance takes time and effort, and
And frequently parking influences whole year production task for a long time, influences the performance of enterprises.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art normally to transport in coal gas cooling device there is provided one kind
When row or system shutdown, the anti-clogging in the raw gas cooling procedure for the crystal for removing final cooler and gas exit pipeline
Device.
What the utility model was realized in：A kind of preventing clogging up device in raw gas cooling procedure, including medium-pressure boiler
Supply mains, final cooler and final separator, it is characterised in that：Be provided with described final cooler raw gas import,
It is provided with raw gas house steward, final separator and sets in raw gas outlet, wash tub pipe interface and discharge outlet A, raw gas outlet
Import, outlet and discharge outlet B are equipped with, raw gas house steward's other end is connected with import, and triple valve C is provided with raw gas house steward,
Triple valve A and triple valve B are provided with medium-pressure boiler supply mains, triple valve A is connected with wash tub pipe A, and wash tub pipe A is with rinsing
Waterpipe jointing is connected, and gate valve is connected after being provided with showering guilding valve A, showering guilding valve A connections 8 word blind plate A, 8 word blind plate A on wash tub pipe A,
Wash tub pipe A end, which is provided with shower nozzle joint, shower nozzle joint, is provided with shower nozzle, and wash tub pipe B is provided with triple valve B,
Wash tub pipe B one end is connected with triple valve C, is provided with wash tub pipe B after showering guilding valve B, showering guilding valve B and is connected with 8 word blind plates
B, discharge outlet A are connected with coal gas separator, and discharge outlet B is connected with coal gas separator.
Described triple valve A and triple valve B is reducing flow divider, and triple valve C is reducing converging valve.
Described shower nozzle is Conic nozzle.
Compared with prior art, the beneficial effects of the utility model are：Preventing clogging up device in raw gas cooling procedure is thrown
With rear, it may be implemented in and rough coal gas pipeline water is boiled after coal gas cooling device operation and system shutdown, rinsed, it is to avoid because raw gas is total
Pipe pressure height causes gasification furnace to be difficult to heavy-duty service, while reducing water boils frequency, adds the on-line operation rate of the present apparatus；
By periodically boiling, rinsing to rough coal gas pipeline water, pressure difference between raw gas house steward and gasification furnace can be effectively reduced, it is to avoid gasification furnace
Because raw gas manifold pressure Gao Erjia does not play load；By periodically boiling, rinsing to final cooler water, changing for heat exchanger is added
Thermal effect, ensures that process producing index in normal control range, reduces the scavenging period and cost of heat exchanger in device, saves
After preventing clogging up device in energy consumption reduction, raising company productivity effect, raw gas cooling procedure comes into operation, realize to final cooler pipe
The total inside pipe wall crystal on-line rinsing of journey, raw gas disappears stifled, and plant running load is not influenceed.
