The utility model is applicable to the bulk cement flowing tank, and has the advantages of good dust removal effect and automatic control of dust removal.
Description
Technical field
The utility model relates to instrument for building, especially a kind of bulk cement current tank dust collector.
Background technology
According to State Environmental Protection Administration's measuring and calculating, the loss that China's environmental problem is caused accounts for 10% of gross national product, and pollution problem is very serious, so environmental demands is also strict day by day, and country is to flue dust and SO
2Discharging exacting requirements is more proposed.Be accompanied by the step of expanding domestic demand, building quantity is more and more, and the bulk cement requirement increases progressively day by day, but environmental issue still can not be ignored.According to the end of the year 2006 statistics, national cement bulk rate has only 39.13%, and the bulk cement current tank that is distributed in each scene, large, medium and small building ground has 10.89 ten thousand, and surplus also will increasing 10,000 newly every year.Because bulk cement tank is not equipped with dust pelletizing system, bulk cement tank stores cement is again to unload conveying cement by special-use vehicle gas in jar, its gas, solid (cement) two-phase are separated in current tank, cement is by the gravity natural subsidence, dusty gas has caused the pollution of atmosphere and the loss of cement through the direct exhaust to atmosphere of deflation hole.Therefore bulk cement tank causes the pollution of environment and the loss of cement when storage cement, sums up according to field experience, and 65 tons of cement of every storage will have 1 ton cement loss.If can not fundamentally solve this dedusting difficult problem, bulk cement will cause tremendous influence to environment.Therefore, on the bulk cement current tank, dust collector is installed,, is improved environmental quality, reduce the cement loss, will play facilitation, and be the favourable development environment of bulk cement construction reducing cement dust content.The dust collector of existing bulk cement current tank comprises and stretches into that via flow jar (storehouse) top is incorporated into the induced duct of low level with exhaust and hang dust-removal cloth-bag in the induced duct exit, the bulk cement current tank dust collector of this kind structure is after the cement loading finishes, need manually cloth bag to be cleared up recovery, labor strength is big.
The utility model content
The utility model purpose provides a kind of bulk cement current tank that is suitable for and uses the bulk cement current tank dust collector of good dedusting effect, automatic guidance deashing.
For realizing above-mentioned technical matters, the technical solution adopted in the utility model is as follows: a kind of bulk cement current tank dust collector comprises casing, is suspended on filter bag, gas feeder and winding-up pipe in the casing, the winding-up pipe is located at the top of filter bag, gas feeder is connected with the winding-up pipe, between gas feeder and winding-up pipe, be connected to pulse valve, sack at described filter bag is provided with Venturi tube, and the winding-up pipe faces the Venturi tube place and is provided with spray orifice.
Described filter bag is installed in the casing by the filter bag framework.
Described filter bag adopts the polyphenylene sulfide Needled mat to make.
After the utility model adopts said structure, by casing being set, being suspended on filter bag, gas feeder and winding-up pipe in the casing, the winding-up pipe is located at the top of filter bag, gas feeder is connected with the winding-up pipe, between gas feeder and winding-up pipe, be connected to pulse valve, sack at described filter bag is provided with Venturi tube, and the winding-up pipe faces the Venturi tube place and is provided with spray orifice.Fine dusts in the dirt wind is arrested in the filter bag outer wall, plays good dust removing effects; Send signal by pulse instrument, pulse valve is opened in control in proper order, the pressurized air of gas feeder is ejected into cooresponding venturi tube by each spray orifice of winding-up pipe, pressurized air sprays into filter bag at a high speed by the clean air that Venturi tube quickens the injection power inducing peripheral of generation, make filter bag rapid bulging of moment, because the very fast disappearance of impact effect of reverse impulse air-flow, filter bag sharply shrinks again, the vibration of the Chan Shenging dust that will be attached on the filter bag filtering surface strips down like this, reach automation cleaning filter bag cement, pulse jet intensity and frequency can be regulated, and ash-removal effect is good, and greatly reduce working strength of workers.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 Venturi tube air intake schematic diagram.
Among the figure: 1 casing, 2 filter bags, 3 gas feeders, 4 winding-up pipes, 41 spray orifices, 5 pulse valves, 6 Venturi tubes, 7 filter bag frameworks, 8 pulse instruments.
The specific embodiment
Shown in Fig. 1 and 2, bulk cement current tank dust collector of the present utility model comprises casing 1, is suspended on filter bag 2, gas feeder 3 and winding-up pipe 4 in the casing 1, winding-up pipe 4 is located at the top of filter bag 2, pass through plumbing connection between gas feeder 3 and the winding-up pipe 4, between gas feeder 3 and winding-up pipe 4, be connected to pulse valve 5, sack at described filter bag 2 is provided with Venturi tube 6, and winding-up pipe 4 faces Venturi tube 6 places and is provided with spray orifice 41.Above-mentioned filter bag 2 is installed in the casing 1 by filter bag framework 7.On casing 1, also be provided with the pulse instrument 8 of control wave valve 5, described filter bag 2 adopts the polyphenylene sulfide Needled mat to make, the filter bag 2 of this kind material has specific density and permeability to air, good anti-corrosion, resistance to effect of heat and higher mechanical strength are arranged, the fiber that resistance to heat is good, its thermal endurance can reach 250～350 ℃ at present.The dust exhaustor of pulse backblowing filter bag is because its pulse jet intensity and frequency can be regulated, so ash-removal effect is good.To be dust laden air entered in the casing 1 by the ventilation inlet of casing 1 its principle of work, and fine dusts is because the multiple effect effect of filter bag 2 is arrested in filter bag 2 outer walls.Purified gas is discharged through venturi tube 6 by filter bag 2.Along with the growth of period of service, the dust of filter bag 2 adsorption increases, and the permeability to air of filter bag 2 weakens, and the dust collector resistance is constantly increased.For guaranteeing that dust collector in-to-in resistance is controlled within the restricted portion, send control signal by pulse instrument 8, open pulse valve 5 in proper order, make the pressurized air in the gas feeder 3 be ejected into cooresponding venturi tube 6 (being called wind one time) by winding-up pipe 4 each spray orifice 41, pressurized air (is called secondary air by the clean air that Venturi tube 6 quickens the injection power inducing peripheral of generation, the 4-6 that is equivalent to the high pressure draft volume is doubly) spray into filter bag 2 at a high speed, make filter bag rapid bulging of 2 moments, because the very fast disappearance of impact effect of reverse impulse air-flow, filter bag 2 sharply shrinks again, the vibration of the Chan Shenging dust that will be attached on filter bag 2 filtering surfaces strips down like this, reach the automatic ash removing purpose, greatly reduce the labour intensity of the artificial deashing of workman.The dust that falls is discharged through dust-exbaust system.The utility model is suitable for the bulk cement current tank to be used, and improves the degree of utilization of bulk cement, and degree of utilization almost reaches 97%, can not occur the situation of 1 ton of 65 tons of cement loss of every filling again.Reduced the pollution of bulk cement, reached the effluent standard of flue dust environment.The utility model efficiency of dust collection height, one-time investment is economized, and equipment takes up an area of little, and operating cost and pollution charge are low.
