Description
Technical field: the present invention relates to a kind of filter, especially a kind of Based Intelligent Control coal gas natural gas filtering system.
Background technology: in metallurgy industry blast furnace ironmaking process, utilize coal gas to heat to blast furnace, the coal gas of coke-oven plant's output is containing tar, sulfur dioxide, naphthalene, dust, suspension and water, these materials can be blocked stokehold nozzle, make gas output deficiency, cause high furnace temperature inadequate, affect furnace processor, therefore need a kind of filter that above-mentioned dregs are removed, existing two kinds of filter methods:
1., the first is to utilize charcoal absorption dregs method to remove dregs in coal gas, there is following point in this kind of technology, the one, workman needs frequent disassembly, cleaning filter, change active carbon, increase workman's working strength, the 2nd, the active carbon that is stained with dregs is difficult to process, and causes secondary pollution.
2., the second is to utilize filter core method to remove dregs in coal gas, this kind of technology existing problems, filter core is crossed in the frequent disassembly, cleaning of workman, increases workman's working strength.
Summary of the invention: for above-mentioned the deficiencies in the prior art, the invention provides a kind of Based Intelligent Control coal gas natural gas filtering system that can not cause secondary pollution, alleviate workman's working strength.
For achieving the above object, the technical solution used in the present invention is: Based Intelligent Control coal gas natural gas filtering system, comprises oil expeller, self-skimming filter, automatic dehydration filter and control cabinet.The gas outlet of oil expeller is connected with the air inlet of self-skimming filter, and both bottoms all connect residue receiving box by electrical ball valve.The gas outlet of self-skimming filter is connected with the air inlet of automatic dehydration filter.The bottom of automatic dehydration filter connects electrical ball valve.Control cabinet is connected with oil expeller, self-skimming filter, automatic dehydration filter, electrical ball valve.
Preferably, described slag case upper end is provided with the exhaust stack being communicated with atmosphere.
Preferably, the gas outlet of oil expeller is connected with the air inlet of self-skimming filter with vertical nozzle by horizontal nozzle.
Preferably, on oil expeller, be also provided with air inlet.
The present invention, in the situation that not affecting normal work, realizes filtering function, by notch cuttype filtration treatment, makes processing procedure more targeted, processes more thorough.It is fixed time cleaning and differential pressure cleaning online, and the dregs after cleaning can focus on, and can not cause secondary pollution, alleviate workman's working strength.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment:
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out to clear, intactly description, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1: Based Intelligent Control coal gas natural gas filtering system, comprises oil expeller 1, self-skimming filter 10, automatic dehydration filter 11 and control cabinet 13.The gas outlet of oil expeller 1 is connected with the air inlet of self-skimming filter 10 with vertical nozzle 8 by horizontal nozzle 2, and both bottoms are all passed through electrical ball valve 3 and connected residue receiving box 4.The gas outlet of self-skimming filter 10 is connected with the air inlet of automatic dehydration filter 11.The bottom of automatic dehydration filter 11 connects electrical ball valve 3 by pipeline.Control cabinet 13 is connected with oil expeller 1, self-skimming filter 10, automatic dehydration filter 11, electrical ball valve 3.Described slag case 4 upper ends are provided with the exhaust stack 6 being communicated with atmosphere.On oil expeller 1, be also provided with air inlet 14.
Operation principle:
The present invention adopts staged filter method to filter, and by slightly increasing step by step filtering accuracy to smart each monomer, oil expeller Main Function is by cyclonic action, the tar in medium, sulfur dioxide, naphthalene, dust and a small amount of water to be separated with pumped (conveying) medium.Gas after filtering is discharged by top pipeline, enters and in automatic impurity removing filter, carries out secondary filter, and the impurity after oil expeller separates is due to Action of Gravity Field, under be discharged in slag case, centralized recovery, prevents secondary pollution.The medium that still contains a small amount of particle after once filtering is carried out secondary filter by automatic impurity removing filter, under impurity after filtration is same, be discharged in slag case, cleaning medium after filtering enters in three grades of automatic dehydration filters, the dust removal process of dewatering, reaches pure, dry effect through several procedures medium after treatment.Its function of oil expeller is in oil expeller, to do centrifugal motion with dregs gas, to realize coarse filtration by centrifugal motion.Its function of horizontal nozzle is gas output.When being deslagging, its function of electrical ball valve blocks gas.Its function of slag case is to be to collect dregs.Its function of exhaust stack is the gas of emptying slag case.Its function of vertical nozzle connects oil expeller and self-skimming filter is used.Its function of self-skimming filter is that suspension is filtered out.Its function of automatic dehydration filter is that hydrone in gas and fine dust are filtered.Its function of control cabinet controls differential pressure and timing backwash is used.
The control of a whole set of filtration system adopts complete intelligent Mechatronics control.
Intelligent control principle:
From original source of the gas enters filtration system operation, all valves relevant with system and electric operator are all subject to intelligent electro-mechanical system control.A whole set of control system can realize automatic control and manually control conversion mutually, automatically controls the time that is provided with and controls and two kinds of control modes of differential pressure control.
Filter process:
In the time that whole system enters filter process, the electrical ball valve of oil expeller 1, residue automatic discharging filter 10, automatic dehydration filter 12 is closed, and the each equipment of whole system carries out filtration, purification processing step by step according to function separately to original source of the gas.
Backwash process:
In the time that system reaches preset value (differential pressure is set and the time is set), system enters automatic backflushing washing procedure, automated system is sent signal, with residue automatic discharging filter, automatic dehydration filter connects electrical ball valve and opens, residue automatic discharging filter, executing agency of automatic dehydration filter portion starts, drive filter interior sucker to rotate, residue automatic discharging filter is discharged to the molecule in filter in slag case by electrical ball valve, automatic dehydration filter is discharged the moisture content in filter and small dust by electrical ball valve, after the backwash time of system setting puts in place, the electric operator of two filters stops operating, electrical ball valve is closed, system backwash is complete.Whole system enters filtration condition, the next backwash process of system wait.
In addition, certain hour is set in system the electrical ball valve of oil expeller is controlled, according to the containing filth amount of original source of the gas number, the adjustment time set, regularly drive valve, periodical blowdown.
