In recent years, with the development of science and technology, sterilization equipment has been continuously updated. Pulse vacuum pressure cooker has replaced the lower exhaust pressure cooker. An electric steam heating vacuum boiler replaces an old-fashioned boiler where coal burns to produce steam. The electric steam boiler equipment has many advantages, but the performance has also changed. In order to ensure the safe use of the equipment and prolong the service life of the equipment, some experiences have been accumulated in the correct installation and commissioning of the equipment after several years of research. When the steam boiler leaves the factory, the staff shall carefully check whether the physical items are in full conformity with the list details, and must ensure the integrity of the equipment. After delivery to the installation environment Equipment and components need to be placed on a flat and spacious floor to avoid damage to brackets and pipe seats. There is also a very important point is that after fixing the electric steam boiler, carefully check the boiler and the base contact place whether there is a gap, to ensure that the tight seam, there are gaps should be filled with cement and so on. At the time of installation, the most important component is the electrical control cabinet, need to connect all the wires in the control cabinet to each motor, then install it. There is still a series of commissioning work to be done before the steam boiler is put into operation. The key two steps are liter. Fire and gas supply. It is necessary to control the temperature strictly and not to increase the ground too fast in order to avoid the non-uniform heating of every component and affect the service life of the boiler after the boiler has no loopholes in the equipment. The temperature of the boiler should be strictly controlled during the process of fire-raising and the temperature should not be increased too fast. At the beginning of the gas supply, the heating operation should be carried out first, that is to say, the steam valve should be slightly opened, allowing a small amount of steam to enter, playing the effect of preheating the heating pipe, and paying attention to the normal operation of each component at the same time. After these steps, the steam boiler can be used normally.
Boiler feed water preparation device preparing process advantages and disadvantages current power heating vacuum boiler feed water system ultrapure water substantially above three processes, rest of the process are carried out with different combinations of the three basic process on the basis of the above derived. Their disadvantages are now listed in the following: 1, a first ion exchange resin is advantageous in that low initial investment, space occupied, but the disadvantage is the need for frequent regeneration of ions, pH-consuming, but also for the environment certain destructive. 2, the second stage reverse osmosis equipment, which is characterized by the early administration level attained manner using ion exchange resin is higher, but without resin regeneration. The disadvantage is that the original film is related to be cleaned or replaced regularly, the water quality is not too high, relatively speaking, most can do about 1us / cm. 3, the third reverse osmosis for pre-matched electro-deionization (EDI) apparatus, which is ultra-pure water system to take the preparation of ultrapure water most economical and environmentally friendly, it does not require regeneration with acid continuous Preparation of ultrapure water, no environmentally destructive. The disadvantage is that the initial investment is relatively above two methods are too expensive. High-pressure boiler feed water treatment equipment for industrial and mining enterprises and medium-sized thermal power plant and boiler feed water treatment. The world's most advanced reverse osmosis membrane element, pressure vessels and other equipment, supported by reasonable and have a pre-processing and post-processing equipment, can produce boiler feed water in line with national or industry standards (GB1576-79, DL / T561-95) super pure water. In the membrane treatment system, used typically ultrafiltration pretreatment 1mm diameter hollow fiber, to remove suspended solids and colloids in raw water, the biggest problem is the pretreatment as UF membrane fouling and membrane clogging for this often provided at the front pre-filter, to remove large particle suspension was pre-filtered before flocculants, such as PAC (poly acrylic acid) can improve the filtration quality, and reduce the membrane resistance. The amount of dissolved oxygen to the boiler feed water system of the plant required for the general requirements 0.3mg / L or less, for degassing membrane should be operated at a vacuum of less than 5.33Kpa (40TORR) a. IPC programmable control system control, automatic start and stop, dosing and flushing, automatic monitoring of various operating parameters, for production management.
Which of the atmospheric or vacuum or hot water heating vacuum boilers needs to be discharged? Atmospheric pressure boilers and vacuum boilers in gas-fired hot water boilers, which require sewage discharge operation in the course of operation, are for atmospheric pressure hot water boilers, and vacuum hot water boilers do not need to do this work because: atmospheric pressure hot water boilers, All the system water enters the boiler, and the boiler burns high temperature water. After the treatment of the soft water equipment, the system can only remove most of the calcium and magnesium ions in the water, but a small amount will enter the boiler. Therefore, when the calcium and magnesium ions reach a certain concentration, it is necessary to carry out the sewage discharge operation in order to avoid the boiler operation problems due to the existence of these ions.
Jinzhou construction and installation company needs an electric heating hot water heating vacuum boiler house construction, after screening and comparison of various brand boiler industry, our excellent results in the cleaning of the boiler industry has been attracted to each other, in mid-2016, the Jinzhou construction and installation the company I signed with an electric heating pressure hot water boiler.Free Chat
