Description
Technical field
The present invention relates to a kind of coal gas scrubbing tower.
Background technology
Adopt the fixed bed intermittent type to make the coal gas scrubbing tower of semi-water gas in the Ammonia Production, comprising tower body, tower body top has water jet standpipe, escape pipe, the tower body bottom has inlet pipe, rising pipe, be after semi-water gas reclaims heat indirectly by waste heat boiler temperature at 180-200 ℃ of gas washing cooling system that contains a large amount of unconverted water vapors, the general direct hollow-spraying-tower of water coolant that adopts, coal gas enters at the bottom of tower, water coolant counter current contact with under the cat head spray reaches the effect to the gas washing cooling.
One, the proposition of problem
This traditional scrubber tower, generally used for a long time by the Coal Chemical Industry industry, yet have following point:
1, the heat of the coal gas water that is cooled is taken out of, can't reclaim.General inlet air temperature 180-200 ℃, air outlet temperature 35-40 ℃, single stove gas forming amount is with 5000-6000m
3/ h meter, the heat of its loss is conspicuous.
2, the heat of phase transformation of institute's moisture vapor can't reclaim equally in the coal gas.General gas furnace hour steam inlet 3-5 ton/hour, and steam decomposition rate about 40%, part producer is no more than 40%, and promptly most of water vapor is to enter scrubber tower to be got off by water condensation and emit a large amount of gasification latent heats to enter in the water coolant.
3, hollow-spraying-tower gas distribution inequality, gas-to-liquid contact is bad, and the cooling performance of tower is relatively poor.
4, the scrubber tower water consumption is big, and the thermal load of recirculating cooling water system is heavier.The hot water that generally goes out scrubber tower is at 70-90 ℃, the cooling performance of summer in winter and recirculated water cooling equipment directly influences air outlet temperature, sometimes do not guarantee exhaust gas body temperature degree index, go into tower and recycle and a large amount of hot water (general single tower is greater than the water yield of 150T/h) that go out tower need be cooled to 30-35 ℃, be the waste of heat energy on one side, Yi Bian be the consumption of handling the water coolant expense.
Summary of the invention
The purpose of this invention is to provide a kind of energy-conservation coal gas scrubbing tower.
To achieve these goals, the technical scheme that the present invention takes is: a kind of coal gas scrubbing tower, comprising tower body, tower body top has water jet standpipe, escape pipe, the tower body bottom has inlet pipe, rising pipe, its characteristics are: on the sidewall of tower body cavity middle part dividing plate is installed, dividing plate is divided into the tower body cavity, following two sections, epimere is the washing temperature descending section, hypomere is the water vapor condensation heat recovery section, have gas flue on the dividing plate, have the coal gas through hole in the gas flue, the gas flue upper end of coal gas through hole top is equipped with and rises gas cap, it is corresponding with the coal gas through hole to rise gas cap, on the tower body cavity, following two sections communicate by the coal gas through hole, on the tower body cavity epimere lower sides rising pipe are installed, and on the tower body cavity hypomere upper portion side wall water jet standpipe are installed, in the tower body cavity hypomere heat pipe soft water heater is installed, the heat pipe soft water heater is comprising vacuum heat-pipe, heating tube, vacuum heat-pipe is built-in with liquid heat-transfer medium, is covered with the vacuum heat-pipe of oblique cutting around the heating tube outer side wall from top to bottom; The vacuum heat-pipe outer end places in the tower body cavity, and vacuum heat-pipe is inner to be inserted in the heating tube, and heating tube top is equipped with the soft water inlet pipe, the bottom is equipped with soft water and goes out pipe, and soft water inlet pipe, soft water go out pipe and passes the tower body sidewall respectively.
On the water jet standpipe of installing in the described tower body cavity hypomere shower nozzle is installed.
The shower nozzle of installing in the described tower body cavity hypomere is a spraying nozzle.
Advantageous effect of the present invention is: the present invention in use, tower body cavity epimere is the washing temperature descending section, hypomere is the water vapor condensation heat recovery section, and the heat pipe soft water heater places hot water at the bottom of the tower, latent heat of emitting with the water vapor cooling of reclaiming in the semi-water gas and semi-water gas with sensible heat.Feed cold soft water in the heating tube in the heat pipe soft water heater, heating back boiler of feeding is produced steam and is used.Feed water coolant in the water jet standpipe of installing in tower body cavity hypomere, spraying nozzle is installed on the water jet standpipe, water coolant is with vaporific ejection and coal gas uniform contact, temperature is controlled at 90-98 ℃, except that reclaiming gas heat, mainly allow water vapor condensation liquefaction in the coal gas, to reclaim its heat of phase transformation.Heat is recycled by heat pipe soft water heater heating soft water.The heat pipe soft water heater is to insert liquid heat-transfer medium in vacuum heat-pipe, according to the grade quality that reclaims heat, selects the different material of boiling point for use, and its heat-transfer medium is in vacuum heat-pipe, and thermal source one end absorbs gas heat, emits heat of phase transformation to cooling one end again.Because what transmit is heat of phase transformation, so the recovery of heat effect is splendid, the present invention can be heated to 70-80 ℃ to soft water, and recovery of heat is respond well.Rise gas cap owing to have among the present invention, rise gas cap and only allow the coal gas that is recovered behind the heat of tower body cavity hypomere pass through.Tower body cavity epimere still is a hollow-spraying-tower, and recirculated cooling water with the coal gas counter current contact that is reclaimed by tower body cavity hypomere behind the heat, is further cooled to the productive capacity from cat head spray down.The water coolant of tower body cavity epimere goes out the tower body cavity above central dividing plate, do not allow the low water of this part relatively large temperature enter tower body cavity hypomere, to guarantee the heat recuperation effect of hypomere.The water coolant of tower body cavity hypomere is discharged at the bottom of tower, and upper and lower section water that goes out the tower body cavity is sent into the cooling processing of cold water system, recycles after the processing.The outside fishbone shape of heat pipe soft water heater has also played the sparger effect of gas, rises the effect that gas cap has also played the gas reallocation, has eliminated former void tower skewness, the bad drawback of gas-to-liquid contact, and the heat-transfer effect of whole tower is better.
