Modified starch absorbable hemostasia material and preparation method thereof

The invention discloses an absorbable haemostatic material of a modified starch and a preparation method thereof. The haemostatic material is etherified modified starch or a composition which is formed by one or two or more than two of the etherified modified starch, cross-linked and composite modified starch, with a molecular weight of 15,000 to 2,000,000, a grain diameter of 10-1000Mu m and a water absorbency of 1 time to 100 times. The modified starch absorbable haemostatic material has the advantages that: the haemostatic material with biocompatibility is directly applied to bloody surface of wound to stop bleeding immediately, obviously increase the water absorbency and the water absorbing speed and have more viscosity and viscidity, thereby simultaneously blocking up damaged tissues and blood vessels while stopping bleeding. The haemostatic material is easy to swell or dissolve in water and after stopping bleeding, normal saline is used for washing to eliminate the haemostatic material not participating in stopping bleeding, thus reducing residues in the body, being beneficial to wound healing, and avoiding pains caused by unclosing pledget and bandage. The haemostatic material has the physical and chemical properties of stability, difficult decomposition, long guarantee period, convenient storage, high pressure resistance, low pressure resistance, high temperature resistance, low temperature resistance and difficult change.

Processing method for preparing bricks by utilizing urban domestic sludge

The invention discloses a processing method for preparing bricks by utilizing urban domestic sludge, which relates to the processing and the utilization of the urban domestic sludge. The processing method comprises the following steps: granulating and drying the sludge for aging; uniformly mixing aged granular materials with shale or clay or coal slag or building rubbish according to the proportion by weight; after the mixing, adding an amount of water for preparing brick blanks and continuing stirring and mixing; preparing the blanks; sintering the blanks; and preserving heat and cooling the blanks to obtain the bricks. The invention greatly saves resources and provides an active sludge processing and utilizing scheme. Some of the strength indexes of the prepared bricks even exceed those of the bricks prepared by ordinary processes. During roasting, for the condition that tail gas generated in the process of roasting the sludge bricks contain more sulfur and chlorine ingredients, a combined desulphurizing and deodorizing technology inside and outside a furnace is used, namely, the limestone is added in to a burning furnace, and water is sprayed to the tail gas under a sealing condition, thus a desulphurizing reactor does not need to be arranged on a tail part so as to ensure that smoke gas reaches an emission standard.

Method for drying sludge by blade drier

The invention provides a sludge paddle desiccation method, which comprises the following steps: loading wet sludge into a paddle desiccator with a charger, indirectly heating materials through a hollow blade heating shafts and a shell jacket with thermal medium, the heating shafts intermeshied and rotating, with squeezing and relaxation alternative action, materials dried and moving to a discharge door simultaneity. The wet share evaporated in drying process is carried and discharged with carrying gas, and the carrying gas can enter from a carrying gas inlet or the discharge door, and is ejected from exhaust outlet. The heating shafts of the desiccator can be two shafts, or four shafts. The wet share discharged from the desiccator is washed, dedusted and deodorizated with a washing tower to reach the emission standard, and evacuation with a induced fan. The invention has the characters such as small energy consumption, low operating cost, small equipment plot area and equipment investment, big operating flexibility, stable and reliable operation, little entrained dust and material depletion. The invention settles the technical roadblock of huge dedusting equipment, high operating cost of hot-air sludge desiccator or short periodic motion caused by frequently sticking wall in other sludge desiccation.
