The invention discloses a device for treating the scaling phenomenon of a chemical pipeline. The device comprises a left descaling body and a right descaling body, a motor is fixed on the rear end surface of the right descaling body, the left descaling body and the right descaling body are connected through a telescopic shaft, and the left descaling body and the right descaling body are both located on the chemical pipeline. The device is simple in structure and convenient to operate, solves the problem of stubborn scale body residues caused by incomplete descaling, meanwhile, can greatly improve the descaling efficiency, shorten the descaling time and reduce the cost after descaling, when the device is used, the inner wall of the pipeline can be firstly scraped back and forth by using thedevice, so that removal of stubborn scale bodies is guaranteed, then the descaling pipeline is filled with cleaning liquid, therefore the purpose of descaling is thoroughly achieved, and the effectsof quickly descaling and greatly shortening the descaling time can be achieved.

The invention discloses a descaling method which comprises the step that a liquid flows through a scaling unit (2) with the contact area of 10-30m<2> at a flow rate of 0.001-0.004m / s. The invention further discloses descaling equipment and a descaling system. The descaling method can descale the liquids (particularly wet crude produced liquids), is low in cost and convenient to operate, and does not affect normal oil extraction operation.

The invention relates to the technical field of earphone maintenance equipment, and discloses a round earphone cover surface wiping equipment, which includes a cylinder body, the middle position of the top of the cylinder body is fixedly connected with a handle by screws, and the inner walls of the left and right sides of the cylinder body are fixedly connected There is an installation partition, the top middle of the installation partition is fixedly connected to the battery, the bottom middle of the installation partition is fixedly connected to the low-speed motor through bolts, and the ring side of the inner bottom of the cylinder is fixedly connected to the connection ring, the connection ring The inner side of the cylinder is movably connected with a rotating disc through movable balls, and the output shaft of the low-speed motor is fixedly connected to the middle position of the upper surface of the rotating disc by screws. Half ring button hood. The equipment for wiping the surface of the circular earphone cover is equipped with wiping cotton to contact, wipe and descale the earphone cover, thereby improving the quality of dirt wiping on the large plane surface of the earphone cover and achieving the purpose of descaling.

The invention discloses an environment-friendly type boiler scale remover which is prepared from the following raw materials in percentage by weight: 10-50% of phytic acid, 5-10% of citric acid, 3-5% of glucose and the balance of water. The environment-friendly type boiler scale remover disclosed by the invention has the advantages of high efficiency, small application amount, low application cost, environmental friendliness, no pollution, small corrosion speed on equipment surface, and convenience in operation as equipment does not need to be hauled in descaling.

The invention discloses a scale-removing and anti-scaling alloy, which comprises the following raw material components in terms of mass percentage: 71%-75% of copper, 6%-10% of nickel, 0.5%-3% of tin, and 5%-15% of zinc , lead 6.5%~10%; The present invention also discloses the descaling device and preparation method that adopts said descaling and antiscaling alloy to make; Combining the above 5 elements to conduct electric The chemical action makes the electron transfer of various ions, separates and becomes a single molecular crystal, which exists independently in the water, plays the role of anti-scaling, has good effect of descaling, and the anti-scaling rate is as high as 97.37%, which improves the production efficiency and reduces the pollution emission is reduced, and the service life of the equipment is prolonged; on average, a heat exchange equipment installed with the scale inhibitor of the present invention will save gas costs (552965+238041) ÷ 2 = 395503 yuan in one year, and the catalyst of this alloy material The lifespan is very long, so it is more economical for continuous use.

The preparation of a kind of descaling and antiscaling agent used in the deashing water system provided by the present invention is prepared raw materials in parts by weight, consisting of 28-35 parts of itaconic acid-styrenesulfonic acid-acrylic acid copolymer, 27 parts of polyol phosphate -36 parts, 16-23 parts of glycolic acid, 19-25 parts of pure water; its best preparation: 30 parts of itaconic acid-styrenesulfonic acid-acrylic acid copolymer, 30 parts of polyol phosphate, 20 parts of glycolic acid, It is composed of 20 parts of pure water; when preparing, add pure water first, then put its components into the reaction kettle in turn, stir for 40-50 minutes, and control the temperature at 20-35°C to obtain the product; among them, itaconic acid-styrenesulfonic acid- For the synthesis of acrylic acid copolymer, take 10-14 parts of itaconic acid, 5-7 parts of styrenesulfonic acid, 3-5 parts of isopropanol, and 30-38 parts of pure water, put them into the reaction kettle in turn, stir, and heat to 95°C , dropwise add 22-25 parts of acrylic acid and 2 parts of ammonium persulfate solution (dilute with 18 parts of water first), control the dropwise addition within 30 minutes, keep warm for 110-122 minutes, drop to room temperature and discharge, pH value 1.5-2.5 , It can be obtained when it is light yellow transparent liquid. This product is used for descaling and antiscaling of ash removal water in power plants and reinjection water in oil fields, and the dosage is 5-10mg / L.
