Abstract
A cyclone dust extractor for processing phenol wastewater belongs to the technical field of dust collecting equipment. The technical problem needed to be solved is to provide a cyclone dust extractor which uses the heat of coal gas to decompose and gasify the phenol wastewater. The technical scheme of the utility model is as follows: the cyclone dust extractor comprises a dust extractor shell, a coal gas inlet tube and a coal gas outlet tube, wherein the outsides of the dust extractor shell and the coal gas outlet tube are jacketed structures, the lower part of the outer jacket of the dust extractor shell is provided with a phenol wastewater inlet, the lower part is provided with a phenol wastewater steam outlet, and the outer jacket of the coal gas outlet tube is communicated with the outer jacket of the dust extractor shell. The device has the advantages that the phenol wastewater is heated to form the phenol steam and the phenol steam is introduced to the bottom of a gasification burner to be used as gasifying agent, thus realizing non-phenol wastewater emission and achieving the environmental protection requirement; and the heat energy needed in the process of heating phenol wastewater to form steam is from the sensible heat of the coal gas, thus realizing effective use of energy of hot coal gas. The execution effect of the device is that the treating hot coal gas flow is 4000Nm3/h, the temperature of the coal gas inlet is 450 DEG C and the treating amount of phenolic water is 310kg/h.
Description
Technical field
The utility model relates to a kind of tornado dust collector of handling the phenol waste water that produces in the gas production process, belongs to the environmental protection equipment technical field.
Background technology
Gasification of coal is to be most widely used at present and proven technique, and the fixed-bed type producer gas generator is current by the coal gas generation equipment of widespread usage.Cold purified gas is the overall trend of gas station development.Hot raw gas can produce a large amount of phenolic wastewater in cooling in the process of purification, and the gas yield of gas station is big more, and the amount of useless phenol water is also big more.Say that generally one ton of coal of every burning produces about phenol water 50kg approximately, every 1000Nm
3Coal gas produces about phenol 1kg.Contain prussiate in the phenolic wastewater that gas station produced, the COD value has destructive injury up to more than 15000 to human body and farm crop, never allows to discharge, and the method for the phenol of gas station processing at present waste water mainly contains chemical method and burning method.Chemical method at first will precipitate, filter phenol sewage removes impurity and suspended substance, doses chemical agent again and carries out several times and handle and just can make COD value reach country's permission emission standards.This method floor space is big, and one-time investment is higher, and the ton processing cost is also higher, and technology neither be very ripe, and gas station uses seldom at present.Burning method is to adopt incinerator that phenolic wastewater is carried out spray burning.According to research, phenol can decompose 90% greater than 420 ℃ the time, reach perfect combustion and decompose, and should carry out under 800～1000 ℃.Every m burns
3Phenol water will consume 500m
3Coal gas, basically the phenol water of separate unit stove generation will consume the heat of separate unit stove about 1/10th, and its consumption is appreciable, handles the phenol water except that large-scale gas station (ten more than the blind roaster) adopts burning method, none employing incinerator of middle-size and small-size gas station mainly is that the cost high fever does not rise.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of tornado dust collector that can utilize the heat of hot raw gas with the processing phenol waste water of phenol waste water decomposition gasification.
The technical scheme that solves the problems of the technologies described above is:
A kind of tornado dust collector of handling phenol waste water, it comprises fly-ash separator housing, gas inlet pipe, gas outlet tube, and its improvements are that the outside of fly-ash separator housing is a jacket type structure, the import of phenol waste water is arranged at the bottom of fly-ash separator hull outside chuck, and phenol waste water vapor outlet port is arranged at top.
The tornado dust collector of above-mentioned processing phenol waste water, the outside of described gas outlet tube are jacket type structure, and gas outlet tube outside chuck has communicating pipe to be connected with fly-ash separator hull outside chuck.
The major advantage of this device is:
1. pass to the gasification burner furnace bottom behind phenol water heating the becoming phenol steam and cook the vaporized chemical use, realized no discharge of phenolic water, reached environmental requirement;
2. phenol water is heated into steam institute heat requirement from gas heat, realizes effective utilization of heating gas energy;
3. take into account dedusting phenol water disposal the time, kill two birds with one stone;
4. the coal gas circulation duct is simple, does not have blockage problem;
5. coal gas flows at the housing internal rotation and rises the enhanced heat exchange effect.
An implementation result of this device is: handle heating gas flow 4000Nm
3/ h, 450 ℃ of gas entry temperature are handled phenol water yield 310kg/h, reach the ideal effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Mark is as follows among the figure: fly-ash separator housing 1, gas inlet pipe 2, gas outlet tube 3, chuck 4, phenol waste water import 5, phenol waste water vapor outlet port 6, communicating pipe 7
Embodiment
Show among the figure, the utility model is that jacket type structure is all made in general dry type tornado dust collector housing 1 outside and gas outlet tube 3 outsides, phenol waste water import 5 is arranged at the bottom of chuck 4, phenol waste water vapor outlet port 6 is arranged at top, and gas outlet tube 3 outside chucks 4 have communicating pipe 7 to be connected with fly-ash separator housing 1 outside chuck 4.
After adopting this structure, can make full use of the sensible heat (gas outlet temperature is generally at 500 ℃) of hot raw gas, hot raw gas is entered by the whirlwind import, flow and flow out at the cyclone internal rotation by the top outlet, heat efficiently passed to the phenol waste water in the chuck in the eddy flow process, phenol waste water flows in the chuck of the outside of tornado dust collector.This process coal gas discharges sensible heat, temperature reduces, phenol waste water in the chuck is heated indirectly, temperature raises and to be heated to form steam, and phenol steam, is used as vaporized chemical at the bottom of entering producer again in pipeline is introduced the gas collection bag by the top outlet, meanwhile, hot raw gas is in the eddy flow process, because action of centrifugal force also can be removed big dust of granularity and coke tar particles.
