China Drying Network News With the increase of environmental awareness, China's emission control of sulfur dioxide emissions from coal-fired power plants is becoming more and more tight, and desulfurization of power plants is imperative. At present, the desulfurization gypsum treatment process and equipment are not completely the same as natural gypsum, such as material transportation, dust treatment, calcination process, and the like. Desulfurized gypsum is widely used in the building materials industry. It can basically replace most of the building material products produced by natural gypsum through different means. The basic drying and desiccating process of desulfurized gypsum is that the desulfurized gypsum enters into the rotary dryer from the feeding device and is dried in the down stream. The desulfurized gypsum is picked up under the action of the lifting plate of the dryer and scattered into a spiral material curtain. With the hot air heat exchange, the desulphurized gypsum slowly advances under the effect of the dryer's own inclination and the spiral lifting plate, and is finally dried and discharged at the discharge end of the dryer.

Desulfurization gypsum dryer should have the following characteristics: 1, dryer anti-overload capability, processing capacity, less fuel consumption, low cost of drying; 2, desulfurization gypsum dryer adopts co-current drying method, hot air and wet materials by The same side into the dryer, you can use high-temperature air to obtain high evaporation intensity, dryer outlet temperature is low, high thermal efficiency; 3, desulfurization gypsum dryer can change the operating parameters according to different material properties, so that the material in the dryer cylinder Can form a stable full-cut fabric curtain, heat exchange more fully; 4, new feed, discharge device, eliminate the drum dryer feeding blockage, discontinuity, uneven and return to the phenomenon, reducing the dust removal system The load; 5, desulfurization gypsum dryer to achieve a "zero level of thrust", greatly reducing the wear of the retaining wheel, the cylinder running a smooth and reliable; 6, dryer using "aligning type wheel device", so that the roller The contact with the roller is always in linear contact, which greatly reduces the wear and power loss; 7, desulfurization gypsum dryer can control the product moisture according to user requirements.

Desulfurization gypsum dryer

The working principle of the desulfurization gypsum dryer is as follows: The desulfurization gypsum is fed into the inner layer of the multi-layer drum by the feeding device to achieve downstream drying. The desulfurization gypsum is continuously picked up and scattered under the copying board in the inner layer and spirally conveyed to achieve heat exchange. The material moves to the other end of the inner layer and enters the middle layer, and is dried by countercurrent drying. The material is continuously lifted in the middle layer. It is a two-step backward travel mode. In the middle layer, the material fully absorbs the heat dissipated by the inner drum. It also absorbs the heat from the middle drum and at the same time prolongs the drying time, so that the material reaches the optimum dry state. The material goes to the other end of the middle layer and falls into the outer layer. The material in the outer drum is in a rectangular multi-loop manner. The material that achieves the drying effect rapidly moves out of the drum under the effect of hot air. The wet material that does not achieve the drying effect cannot be fast due to its own weight. The material is fully dried in the rectangular copying board to achieve a drying effect and the drying process is completed.

inflatable baby bathtub

The warm water inside the inflatable baby bathtub produced by Lixin Outdoor Product Co., Ltd is separated from the cold ground by two sheets of PVC Material and a layer of air, so that the warm water in the bathtub can be kept warm continuously. There are also independent storage pockets, ergonomic design, horizontal strip anti-slip design, safe and secure. The newly upgraded, enlarged and thickened design can accommodate 6 months to 5 years old babies for longer use.

The Inflatable Bathtub can be used when it is inflated, and it can be folded when not in use, which also solves the problem of space for everyone. In addition, there are many styles of inflatable bathtubs, and there are rich children's illustrations and printing. Inflatable tubs are affordable. The price of an inflatable bathtub is less than half the price of a regular bathtub, and the inflatable bathtub is easy to move. If you want your baby to take a bubble bath in the yard and use the bathtub as a swimming pool, the baby inflatable bathtub can meet your wishes.
