Low-cost coal-fired flue gas various pollutant ultralow emission system and low-cost coal-fired flue gas various pollutant ultralow emission method

The invention relates to a low-cost coal-fired flue gas various pollutant ultralow emission system and a low-cost coal-fired flue gas various pollutant ultralow emission method. The system mainly includes a nitrogen oxide gradient control system, a semidry flue gas purifying system and a wet-type static deep purification system. In the invention, by means of the nitrogen oxide gradient control system, the emitted NOx is less than 50 mg/Nm3 in concentration; by means of the semidry flue gas purifying system, the removal efficiency of SO2 can be reach not less than 90%, the removal efficiency of SO3 can be reach not less than 90%, the removal efficiency of acidic gas can be reach not less than 95% and the dust is less than 30 mg/Nm3; and by means of the wet-type static deep purification system, the PM is less than 5 mg/Nm3 and the removal efficiency of SO2 can be reach not less than 50%. The dust-containing waste water in the wet-type static deep purification system is used for slaking limestone and moistening and activating an absorbent in the semidry flue gas purifying system, so that near-zero emission of the waste water in the system is achieved and finally it is achieved that the pollutant emission concentrations of PM is less than 5 mg/Nm3, the emission concentration of SO2 is less than 35 mg/Nm3 and the emission concentration of SO2 is less than 50 mg/Nm3 in a coal-fired power plant, thereby achieving an ultralow emission requirement of the main pollutant under a condition of the near-zero emission of the waste water.

Method for improving broaching precision of mortises in excircle of wheel disc part

The invention discloses a method for improving the broaching precision of mortises in the excircle of a wheel disc part and belongs to the technical field of aero-engine part manufacturing. The adopted technical scheme is that the method comprises the following steps: installing an excircle process platform with a plurality of angular locating slots on the excircle of the to-be-processed wheel disc part; installing two angular locating slots in the excircle process platform if the number of the mortises in the excircle of the to-be-processed wheel disc part is an even number, and broaching the mortises of the wheel disc part in twice; installing three angular locating slots in the excircle process platform if the number of the mortises in the excircle of the to-be-processed wheel disc part is an add number, and broaching the mortises of the wheel disc part in three times. According to the method disclosed by the invention, the contact area between locating surfaces of the mortises of the part and an included angle is effectively increased, so that the stability of fixture positioning is enhanced. Meanwhile, the part angular displacement caused by an angular component generated by broaching is decomposed. The method is simple in operation and skillful in design. Through the method, the fixture rigidity can be greatly enhanced, the deformation of the broached part is reduced, and the dimensional precision of the part is improved.

T-shaped section profile for aluminum alloy template and unit template structure of aluminum alloy template

The invention relates to a T-shaped section profile for an aluminum alloy template and a unit template structure of the aluminum alloy template. The T-shaped section profile is an integrally-molded aluminum alloy profiled plate and is composed of a groove body and a group of longitudinal reinforcing ribs, wherein the groove body is formed by a rectangular panel and two opposite longitudinal side frames on the back of the panel, and the longitudinal reinforcing ribs are uniformly distributed at the groove bottom of the groove body. The unit template structure comprises the T-shaped section profile of the aluminum alloy template, a transverse side frame, transverse reinforcing ribs and angle reinforcing blocks. The T-shaped section profile has the advantages of being definite in structure and simple in molding, little post processing of the template is required, the processing cost is reduced, and the light weight, safety in use and long service life of the template can be ensured; the construction efficiency is improved, and the standardized and systemized, industrialized production is easier; thus, the template has the advantages of being quick and convenient in disassembly and assembly, firm in mounting, high in construction efficiency and low in construction cost.

Personal protection device

The invention relates to a low pressure drop personal protection device for providing protection against a range of toxic industrial chemicals and chemical warfare agents and capable of being worn by a wide range of users. The device comprises: a flexible polymeric hood in which the polymer is selected to be impermeable to the toxic challenge molecules; a neck seal for sealing the hood about the neck;a half mask for providing connection for a canister; and a low pressure drop canister system for providing chemical protection. The canister may comprise a resiliently flexible, closed cell foam and monolithic activated carbons, the foam having holes slightly smaller than the size of the monoliths so that flow through the canister is through the monoliths. The monoliths may be the result of partially curing a phenolic resin to a solid, comminuting the partially cured resin, extruding the comminuted resin, sintering the extruded resin so as to produce a form-stable sintered product and carbonising and activating configurable the form-stable sintered product. They may be between 5 and 40 mm diameter, preferably 15 to 30 mm and 1-3 cm in length. Each monolith may have a square channel structure wherein the channel size is 100-2000μ and the wall thickness may be 100-2000 μm with an open area of between about 30 and 60%. It may have a surface area of at least 700 m2/g, may be activated to >30 wt % weight loss and may be impregnated with materials selected from metallic additives and triethylene diamine according to the anticipated challenge.
