The installation requirements of Gansu Zhangye Gaotai County dryer need to consider the amount of issues. First, whether the uniformity of the material is up to standard, try to avoid such a fluctuating feeding method, and also consider the drying capacity of the dryer-production capacity. If the progress of the material is far beyond the working capacity of the dryer In this case, the drying work cannot be completed. In order to prevent the sludge particles from clogging, the filter is installed in the filter manual cleaning equipment. The manual cleaning device includes a connecting rod and a spring. The connecting rod end is fixedly connected to the filter. At the other end, there is a handle installed on the connecting rod of the gas collecting hood. The gas collecting hood is linked to the pair of annular bosses. The spring is between the ring projection sleeve and the hood section. When the negative pressure exhaust fan inlet pressure gauge shows that it rises to To a certain extent, it is compressed by the handle link and the ring projection spring pressure, and then the hand is suddenly released, relying on the spring compression force and the gravity filter to vibrate, and the sludge is deposited in the filter to remove the shake. The information recommends that Kashgar start the motor to make the paddle dryer run at no load, and the operation should be smooth without abnormal noise. For speed-adjusting devices, the speed should be adjusted within the adjustable range, and it should be performed slowly during acceleration to determine whether the speed-adjusting characteristics meet the requirements. No-load operation shall not be less than 30 minutes. Vaporizers in high-value medicine are liquid at room temperature. The evaporator can effectively vaporize the volatile liquid into a gas, and can precisely adjust the concentration of the vapor output. The evaporation requires heat, and the temperature around the evaporator is the main factor that determines the rate of volatile evaporation. Modern machines widely use temperature-compensated evaporators, that is, when temperature or fresh air flow changes, an automatic compensation mechanism can be used to keep the volatile evaporation rate constant, thereby ensuring that the output concentration leaving the evaporator is stable. Because of different physical characteristics such as different volatile boiling points and saturated vapor pressures, evaporation has specificity, such as enfluorinated evaporators, isofluorinated evaporators, etc., and cannot be used interchangeably with each other. The evaporator of the modern machine is mostly placed outside the breathing loop, and a separate oxygen flow is connected to it, and the evaporated vapor is mixed with the main flow before being supplied to the patient.

After drying, the moisture content of the sludge reaches 20% -30%. After treatment, the amount of dry sludge per ton reaches 1200-2000 calories (equivalent to 220KG-480KG of coal), which can be mixed into coal to enter the boiler together, completely solving the problems of sludge collection and landfill. The current status and development of equipment are inseparable from the application and equipment of freeze-drying technology. At present, freeze-drying equipment is mainly divided into two types: batch and continuous. The scale of equipment ranges from less than square meters to several square meters. Reactors are widely used in petroleum, chemical, rubber, dye, medicine, food, pressure vessels used to complete the processes of vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, condensation and other processes, such as reactors, reaction pots, decomposition pots, Polymerization kettles, etc .; materials such as carbon-manganese steel, stainless steel, zirconium, nickel-based (Hasner, Monel, Inconel) alloys and other composite materials. Gansu Zhangye Gaotai County sludge dryer can be used in coal-fired power plants, cement plants, treatment plants and other factories, instead of traditional fuels for drying treatment. One important aspect is that sludge can reduce waste emissions and protect the environment. The advantages of sludge drying are no longer elucidated. It is well known that different types of sludge dryers (specific types of sludge dryer information: sludge dryer classification) can dry different types of sludge. Of course, the requirements of the dryer on sludge are different. What are the specific requirements? The inspection requires that the heating chamber of the rising film evaporator consists of many long tubes. The diameter of the commonly used heating tube is 25-50mm, and the ratio of the tube length to the tube diameter is about 100-150. The feed liquid is introduced from the bottom of the evaporator after preheating. It is boiled and rapidly vaporized in the heating tube. The generated steam rises at a high speed in the heating tube. When operating at normal pressure, the appropriate outlet steam speed is 20 ~ 50m / s. The steam speed can reach 100 to 160m / s or more during down operation. The solution is driven by the rising steam, which rises into a film along the tube wall and continues to evaporate. The vapor-liquid mixture is separated in the separator 2, and the completed liquid is led out from the bottom of the separator, and the secondary steam is led out from the top. It should be noted that if the amount of water evaporated from the material liquid is not large, it will be difficult to achieve the above-mentioned steam speed, that is, the rising film evaporator is not suitable for the evaporation of thicker solutions; Scaled materials are also unsuitable. RD Hollow Paddle Dryer Drum Squeegee Dryer Drum Squeegee Dryer is a kind of continuous heating type rotary continuous drying equipment. The lower drum of the rotating drum is a second-hand spray dryer in Gaotai County, Zhangye, Gansu. The thick film is adhered to the drum, and the heat pipe is transferred to the drum, which is transmitted to the outer wall of the drum, and then to the film to evaporate the humidity in the film. Dehumidify to dry the moisture-containing material. The dried material is removed from the drum by a scraper installed on the surface of the drum, and is conveyed to the screw conveyor under the scraper, and the screw conveyor collects and packs the dry material. Development course Haibei sludge bricks can be added to clay to make bricks with a mass ratio of 1: its strength is equivalent to ordinary red bricks and has a fixed amount. It can spontaneously ignite during the process of firing bricks. Used in Gaotai County, Zhangye, Gansu Freeze dryer Vacuum freeze dryer to increase heat. Gansu Zhangye Gaotai County second-hand tube bundle dryer wins the market The principle of freeze-drying is basically carried out below 0 ° C, that is, the product is frozen, and the product is allowed to rise above 0 ° C only when the residual moisture content of the product is reduced in the later stage. Temperature, but generally does not exceed 40 ° C. Under vacuum conditions, when water vapor directly sublimates, it remains in the ice shelf when it freezes, forming a sponge-like loose porous structure, so its volume is almost unchanged after drying. Just add water for injection before reuse and it will dissolve immediately. Freeze-dryer is relatively conventional. Freeze-drying has the following advantages: * Many heat-sensitive substances will not denature or inactivate. Medical Education Network Collection * When drying at low temperature, some volatile components in the substance are lost very little. Information recommends the requirements of the dryer for electroplating sludge: the sludge containing 80% -90% moisture content is dried, and the moisture content of the sludge after drying reaches 20% -30%. The amount reaches 1200-2000 calories (equivalent to coal 220KG-480KG), which can be mixed into coal to enter the boiler together to completely solve the problems of sludge collection and landfill. standard requirement

According to the operating pressure, it can be divided into normal pressure, pressure and vacuum evaporation operations. Obviously, for heat-sensitive materials, such as antibiotic solutions, fruit juice, etc., should be carried out under reduced pressure. For high-viscosity materials, pressurized high-temperature heat sources (such as heat transfer oil, molten salt, etc.) should be used for heating and evaporation according to the evaporation effect: single-effect evaporation and multi-effect evaporation. If the secondary steam produced by evaporation no longer condenses directly, it is called single-effect evaporation. The secondary steam is used as heating steam, and multiple evaporators are connected in series. The evaporation process is multi-effect evaporation. The protective layer applied to all parts and parts of the quality assurance evaporator shall be firm, uniform and smooth, and shall not have defects such as delamination and corrosion. In short, evaporation is widely used in chemical, food, pharmaceutical and other industries.
