The preparation method includes: adding the vegetable gelatin and the pure water according to the mass percentage, and heating to melt into gelatin liquid; adding the tobacco essence and the atomizing agent into the gelatin liquid, evenly mixing and stirring, and cooling to obtain the gel-state electronic cigarette liquid.The gel-state electronic cigarette liquid has the advantages that the solid and liquid states of the gel-state electronic cigarette liquid can be changed along with temperature, and the gel-state electronic cigarette liquid is good in tobacco tar liquefying condition, safe and reliable.

The invention provides a blocking valve, a grouting sleeve and a prefabricated component connecting method. The steel bar connection grouting sleeve has a sealed space, and can be automatically sealed after grouting, and the grouting degree can be observed in a grouting process. Compared with an existing open sleeve, the grouting sleeve has the advantages that higher pressure can be born in the grouting process, the grouting sleeve can be automatically sealed after grouting, and the grout fullness of the sealed space can be observed in the grouting process, thereby monitoring the grouting quality of the grouting sleeve. The blocking valve, the grouting sleeve and the prefabricated component connecting method can be widely applied to a grouting sleeve connection process in the technical field of building construction.

The invention relates to a distillate dephenolizing process for the middle production procedure of a coal tar processing device. The technical process comprises the following steps: using a dephenolizing washer pump to pump out the unwashed mixed part which comes from a tar distillation plant so as to be mixed evenly and react with basic phenate together in the dephenolizing washer pump; putting the mixed solution into a primary dephenolizing tower to be kept stand and separated into a mixed part and neutral sodium phenolate, wherein the mixed part enters a secondary dephenolizing tower through a mixing nozzle; and in order to further remove phenols in the mixed part, using 10 to 12 percent diluted alkaline to perform secondary dephenolizing on the mixed solution before the mixed part enters the secondary dephenolizing tower. The mixture is kept stand and separated into the basic phenate and a washed mixed part in the secondary dephenolizing tower, the washed mixed part flows into a phenate removing tower automatically and is kept stand and separated out the residual basic phenate in the phenate removing tower, then the basic phenate flows into a basic phenate groove, and finally the washed mixed part enters a industrial naphthalene distillation plant for further processing. The process can reduce the environmental pollution, save energy resources and improve the efficiency.

The invention relates to a pneumatic transmission method for dry dedusting of fine ash in converter gas, which comprises the following steps: S1, constructing a pneumatic transmission system for dry removal of dust and fine ash in converter gas; S2, material feeding: discharging ash into a first bin pump (13) or a second bin pump (18); S3, fluidizing: transporting nitrogen from a gas tank (20) into a first fluidizing device or a second fluidizing device; S4, conveying: conveying evenly fluidic gas ash mixture to a fine ash cabin (27) via a pneumatic conveying pipe (26); S5, blowing; and S6, transporting. The invention adopts a dry filter bag deduster with no spark discharge, which thoroughly solves the problem of easy explosion venting caused by a static deduster. By the method, conveying step of fine dust is minimized, and equipment failure rate is substantially reduced. Storage and transportation of ash in the fine ash cabin are not limited by site or distance.
