Abstract
The utility model belongs to boiler auxiliary equipment, more particularly relates to a continuous de-scaling and anti-scaling device of the boiler dust removal desulfurization and de-slag grey water pipe. The utility model is characterized in that: the utility model is composed of a ball sending cylinder, a ball receiving cylinder and a de-scaling ball. An end of the ball sending cylinder and the ball receiving cylinder is respectively provided with a connecting flange, and the other end is respectively provided with a fast-opening blind. The front end of the cylindrical form de-scaling ball in the ball sending cylinder is in bullet shape, and the circumference lateral wall of the bullet shaped end is provided with metal de-scaling brushing. The utility model has the advantage that: without pollution, the defects in the normal acid cleaning de-scaling art are avoided by the grey water pipe pipeline cleaning and anti-scaling art. The de-scaling and anti-scaling can be fulfilled without stopping the boiler. No equipment is required to be added by making use of the original device, and the convenient usage can be carried out only by slightly alternating the pipe.
Description
Technical field
The utility model belongs to boiler fixture, relates in particular to a kind of boiler dusting desulfurization of blowing out and scale removal, scale prevention device of the grey water pipe that removes the gred of not needing.
Background technology
Steam, hot-water boiler must be installed desulfation dust-extraction device for satisfying environmental requirement.At present, adopt industrial chemicals such as NaOH, magnesia, calcium oxide to carry out desulfurization, product after its desulfurization and lime-ash cause serious, the fouling fast of pipeline, and hard being difficult to of its quality remove, cause pipeline to stop up, serious even pipeline all blocked.Cause the boiler water supply quantity not sufficient, can not keep the ordinary production operation.Not only therefore increase energy consumption, but also the processing of can not stopping work, affects safety production.After each blowing out, also grey water pipe will be pulled down, manually remove, waste time and energy, dirt is removed not thorough.Therefore buck duct ligation dirt, grey water pipeline stop up has become the difficult problem that the operation boiler needs to be resolved hurrily.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provides a kind of boiler that moves can not need the boiler dusting desulfurization of blowing out and scale removal, the scale prevention device of the grey water pipe that removes the gred.
The utility model for achieving the above object, by the following technical solutions: scale removal, the scale prevention device of a kind of boiler dusting desulfurization and the grey water pipe that removes the gred, it is characterized in that: form by service tube, ball collecting chamber and snaking ball, described service tube, ball collecting chamber one end are respectively equipped with adpting flange, the other end is respectively equipped with fast opening blind, the described interior cylindrical snaking ball front end of service tube that places is warhead shape, and its circumferential side wall is provided with metal snaking bristle.
The beneficial effects of the utility model: ash-water pipeline pigging, preventing fouling have been avoided the shortcoming of conventional pickling descaling technology, and be pollution-free; The boiler of operation can not need blowing out, can finish scale removal, antiscale, utilizes existing equipment, need not acquire equipment, only pipeline is transformed a little and can conveniently be used.
Description of drawings
Fig. 1 is the structural representation of the utility model ball collecting chamber;
Fig. 2 is the utility model service tube mounting structure schematic diagram;
Fig. 3 is the utility model scheme of installation in pipe-line system.
The specific embodiment
As shown in the figure, scale removal, the scale prevention device of a kind of boiler dusting desulfurization and the grey water pipe that removes the gred, form by service tube 2, ball collecting chamber 3 and snaking ball 1, described service tube, ball collecting chamber one end are respectively equipped with adpting flange 4,5, the other end is respectively equipped with fast opening blind 6,7, can keep the pressure in the barrel of sending and receiving the ball.The described interior cylindrical snaking ball front end of service tube that places is warhead shape, and its circumferential side wall is provided with metal snaking bristle 8.The method of this device is installed, is particularly useful for remote pipeline: pump 9, flowmeter 10 are installed in grey water pipe 18 successively, the bypass of service tube are set, ordinarily manometer system 11, by indicator 12, teletransmission Pressure gauge 13, automatic recording instrument 14 and ball collecting chamber.Be connected with the by-pass line of grey water pipe by adpting flange at installation service tube, ball collecting chamber, indicator can be indicated the duty of snaking ball.Be provided with grey water pipeline on service tube top and be connected driving tube 15 bypasses, driver's valve 16 is equipped with in the bypass centre.The course of work: close fast opening blind, and close the valve 17 of grey water pipe, in the middle of opening bypass driver's valve 16 is housed, utilize the energy of water in the pipe to promote to place the cylindrical snaking ball in the service tube to advance, observe snaking ball duty by indicator, teletransmission Pressure gauge, automatic recording instrument, after arriving ball collecting chamber, open the fast opening blind of ball collecting chamber, dirty thing is scraped and discharge with water.
Sent out ball one time in about 10-15 of antiscale cycle days, and can find out experience, determine antiscale service fate at interval according to scale velocity.Utilize the energy promotion snaking ball of water in the pipe to advance, the snaking ball is in the process of advancing, and the scraping action of the metal snaking of utilization bristle own scrapes dirty thing and discharges with water.The snaking ball is the following formula of suffered motive force in pipe:
F＝ΔP×S
ΔP＝P
1-P
2
F-thrust in the formula
P
1-snaking ball rear pressure
P
2-snaking ball the place ahead pressure
S-snaking ball sectional area
If pressure differential deltap P=1kg/cm before and after the snaking ball
2, it is as follows in the different tube diameters snaking ball to be produced thrust F:
| Caliber D (mm) | 150 | 200 | 300 | 500 |
| Thrust | 180 | 310 | 700 | 2000 |
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
