The invention discloses a flue gas desulfurization method and a flue gas desulfurization device. The flue gas desulfurization method comprises the following steps: spraying newly supplemented desulfurizing agent slurry into a desulfurizing tower through the highest spray level of the desulfurizing tower; controlling the sulfur dioxide concentration of the flue gas at the outlet of the desulfurizing tower through adjusting the concentration and / or the spray flow of the newly supplemented desulfurizing agent slurry. According to the flue gas desulfurization method, the newly supplemented desulfurizing agent slurry is sprayed into the desulfurizing tower through the highest spray level of the desulfurizing tower, and the characteristic that the capability of the newly supplemented desulfurizing agent slurry to absorb low-concentration sulfur dioxide in flue gas is far higher than that of a circulating desulfurization slurry with relatively low pH value as the pH value of the newly supplemented desulfurizing agent slurry is far higher than that of the circulating desulfurization slurry is fully utilized, so that the sulfur dioxide concentration of the flue gas at the outlet of the desulfurizing tower can be quickly adjusted; the method directly responses to the target concentration value of the flue gas at the outlet of the desulfurizing tower, and has the advantages of being high in response speed, high in adjustment precision and good in adjustment quality.

The invention discloses salted fish of lemon flavor. The salted fish is prepared from, by weight, 400-450 parts of silver carp, 14-15 parts of pepper leaves, 7-8 parts of fresh hawthorn fruits, 9-11 parts of fresh lemon, 1-1.1 parts of radix glycyrrhizae, 1-1.3 parts of semen cassia, 0.8-0.9 part of fructus tsaoko, 4-5 parts of white granulated sugar, 5-6 parts of Chinese date powder, 3-4 parts of star aniseed powder, 2-3 parts of ginger powder, 15-20 parts of salt and a proper quantity of water. The salted fish is unique in flavor due to the adopted lemon and other auxiliary materials, and the functions of promoting the secretion of saliva or body fluid and tonifying the spleen and promoting appetite and digestion are further achieved; meanwhile such herb ingredients as the radix glycyrrhizae are added, and the salted fish has the effects of tonifying the spleen and qi, clearing heat and moistening the lung.

The invention discloses a casting system and casting method of a cylinder barrel. The casting system comprise a casting mold cavity and a pouring system, wherein the casting cavity comprises a cylinder barrel cavity body, a through hole is axially formed in the cylinder barrel cavity body, the cylinder barrel cavity body is composed of a cylinder barrel head part and a middle body part, the diameter of the cylinder barrel head part is larger than that of the middle body part, a radial protruding block is arranged on the cylinder barrel head part, and a supporting fixing hole and an oil passagehole are formed in the protruding block; the pouring system comprises a sprue, a transverse runner and an inner sprue, the sprue vertically communicates with the transverse runner, the two ends of the transverse runner communicate with the inner sprue through risers, and the inner sprue communicates with a convex block of the casting cavity; and the supporting fixing hole is filled with a first sand core, and an axial through hole of the cylinder barrel cavity body is filled with a second sand core. The casting system has the advantages that parts with the wall thickness of a casting are notprone to shrinkage and loosening defect generating, particularly, the casting defect is not easy to occur among the supporting fixing hole, the oil passage hole and the inner surface of the cylinder barrel, and a chill structure cannot be easily generated in parts with the thin wall thickness.

According to the composition, spina date seeds nourish the heart, benefit the liver and help sleep; ginseng can soothe nerves and promote intelligence; chinese wolfberry can nourish liver and kidney; the jujube can tonify middle-Jiao and Qi; the astragalus membranaceus has the effects of promoting spleen yang and improving body muscle tone; cistanche has the effects of tonifying kidney and supporting yang; and cordyceps militaris can tonify kidney and lung. Gastrodia elata can stabilize liver yang; and the bamboo leaves have the effects of clearing heat and purging fire. The gastrodia elata and the bamboo leaves harmonize the medicines to relieve fire and remove toxin. The composition has the effects of improving immunity, promoting sleep, resisting fatigue, delaying senescence and improving the sub-health state. According to the preparation method, Maotai-flavor liquor is used for soaking the raw materials, alcohol permeates into the raw materials to facilitate separation of effective components in the raw materials, alcohol is used for achieving the sterilization effect to ensure safety and no toxic or side effect of the finished product, the finished product is brewed originally, long in preservation time and can be used by blending, and the taking is convenient.

The invention relates to a manufacturing method of a low-density, high-strength and high-toughness hot-rolled steel plate, the produced steel plate is a Fe-Mn-Al-C austenite low-density steel plate, the density of the steel plate is 6.75-7.05 g / cm < 3 >, and the material lightweight is remarkable. The yield strength of the steel plate is larger than or equal to 800 MPa, the tensile strength of the steel plate is larger than or equal to 900 MPa, the low-temperature impact toughness of the steel plate is kept at a high level while high strength is guaranteed, and the-40 DEG C V-type impact is larger than or equal to 50 J; the steel plate is excellent in machining performance, the material elongation is larger than or equal to 30%, cold bending meets D = 2a and 180 degrees (D represents the bending center diameter, and a represents the steel plate thickness), the surface quality is high, and internal flaw detection meets the requirement that the single defect equivalent flat-bottom hole diameter is smaller than or equal to phi 2 mm and is higher than the NB / T 47013.3-2015 forging ultrasonic detection I-level requirement. The high-strength and high-toughness steel plate is obtained by taking the steel ingot as a material and through an improved heating, multi-process rolling and rolled steel plate cooling mode, and industrial production is realized.

The invention discloses a method for breaking walls of oily microalgae and extracting grease in an assisted manner by virtue of saponification reaction. The method comprises the following steps: (1) adjusting the pH value of a suspension of oily microalgae to 7.5-14 and carrying out hydro-thermal treatment on the oily microalgae; (2) after hydro-thermal treatment, carrying out enzymatic hydrolysis on the oily microalgae in the presence of an enzyme; (3) adjusting the pH value of the oily microalgae to be alkaline for reaction and then adjusting the pH value of the oily microalgae to be acidic for reaction; and (4) adding an organic solvent into the oily microalgae for extracting and separating grease. The method disclosed by the invention is high in grease extraction rate and mild in operating condition, can effectively maintain nutritional components of microalgae, is small in dosage of the organic solvent, environmentally-friendly and low in energy consumption, can be suitable for various microalgae such as nannochloropsis oculata, chlorella, diatom, scenedesmus, single needle algae and the like, and is wide in application range.
