Commissioning method of bypass-free wet desulphurization system of coal-fired unit by means of tiny-oil ignition

ActiveCN102620275AGuaranteed Synchronous Secure BootReasonable durationDispersed particle separationBoiler controlWater treatment systemWastewater
The invention discloses a commissioning method of a bypass-free wet desulphurization system of a large coal-fired unit by means of tiny-oil ignition. A unified formed commissioning method of a hot commissioning specific to bypass-free desulphurization systems does not exist at present. The commissioning method comprises two stages of a cold commissioning and the hot commissioning, the commissioning of a desulphurization process water system and a desulphurization waste water treatment system is required to be completed before the hot commissioning is started, the desulphurization waste water treatment system is used for receiving and processing waste water produced by a desulphurization system, commissioning steps and methods of the rest branch systems are identical to those of corresponding branch systems of a wet desulphurization system with a bypass, and start operation steps in the stage of the hot commissioning are properly adjusted. According to the commissioning method of the bypass-free wet desulphurization system of the coal-fired unit by means of tiny-oil ignition, the cold and hot commissioning processes are adjusted so that the problems existing in a bypass-free system during the hot commissioning are avoided, and the construction period is further reasonably arranged so that the synchronous safe starting of the desulphurization system and a main generator unit is guaranteed.

Design and manufacturing of ultra-large rectangular or oblong-shaped LNG storage tank

Design and manufacturing of an ultra-large rectangular or oblong-shaped LNG storage tank are characterized in that the cross section of a tank body of the LNG storage tank is rectangular or in the shape of an oblong, a stressed layer of the tank wall is made of pre-stressed reinforced concrete in a blocked mode or in an integrated mode, longitudinal, transverse and vertical three-direction pre-stressed reinforced concrete beam frames are arranged in the wall of the tank, a top cover of the tank is in the shape of a one-way arc face or a flat top or a slope, and the top cover of the tank is supported on stand columns. A heat-preserving layer is arranged on an outer layer or an inner layer, or both the inner layer and the outer layer are respectively provided with a heat-preserving layer. A material containing layer is an inner coating layer or an inner adhering layer, or the material containing layer is composed of both the inner coating layer and the inner adhering layer, the inner coating layer is made of anti-leakage, anti-frost crack and anti-corrosion coating, the inner adhering layer is made of low-temperature nickel steel, stainless steel, ceramic or low-temperature-resistant plastic boards, and therefore the high-difficulty design and the high-difficulty manufacturing of the ultra-large LNG tank are converted into design and manufacturing of a large conventional pre-stressed reinforced concrete building, successful and rich experience is achieved in both the design and the manufacturing of the large conventional pre-stressed reinforced concrete building by people, people only need to pay attention to selection and utilization of ultra-low-temperature materials, and the design can guarantee that pressure in a 200000m<3>-400000m<3> LNG storage tank can reach 3mpa. The cost for the design and the manufacturing is several times smaller than that of an existing LNG storage tank, and stress, stability, anti-disaster performance and borne inner pressure of the designed and manufactured LNG storage tank are several times higher than those of the LNG storage tank in existing design.

Method for regulating printing technical parameters of printing machine and other parameters related to printing process

The invention relates to a method for adjusting machine adjustment parameters of a printing press (1) and a printing press suitable for carrying out such a method. The object of the invention is to shorten the repeated adjustments of the printer for new prints during the adjustment of the printing press. The problem is solved in that the machine adjustment parameters (2, 3) adjusted by the printer are stored together with the combined input parameters (8 to 11) in a control device (4) according to a release signal, where there is These adjusted machine adjustment parameters are available for subsequent adjustment of the printing press when corresponding input value combinations are entered. An important advantage of the configuration according to the invention is that the control unit is equipped with a self-learning neural network, by means of which the adjustments of the printer repeatedly changing in the same direction can be weighed accordingly and suggested by the control unit (4) as output values. In addition, in order to simplify the adjustment of the printing press, the present invention proposes the widespread use of (dedicated) barcode readers and smart labels.
