The present invention relates to a filler material for a floor, comprising a natural base material and a mixture containing loess and a resin in powder or pellet form, as well as to a method for producing the filler material. The filler material of the present invention uses the natural base material and is thus environmentally-friendly and not harmful to the human body. Further, in the event rice husks are used as the natural base material, a person slipping on the floor is protected from burning caused by friction as the rice husks have a high moisture content. In addition, the loess contained in the filler material keeps the floor from becoming moldy and emits far infrared radiation, and therefore is beneficial to the human body. The resin emulsion of the filler material prevents the natural base material from generating dust, thus preventing dust from entering the human body via the respiratory organs of the human body. Further, the filler material of the present invention can be easily produced through a simple process. Therefore, mass production of the filler material of the present invention can be accomplished even without employing experts.

The invention discloses a double backpressure condenser optimized operation device and an operation method thereof. The double backpressure condenser optimized operation device comprises a high backpressure condenser, a lower backpressure condenser and a circulating water pipeline, wherein two bypasses and a control valve are arranged on the circulating water pipeline, the bypasses are connected with the two ends of the low backpressure condenser in a crossing manner, and a plurality of temperature measuring points and flow meters are arranged. Compared with the prior art, the double backpressure condenser optimized operation device has the advantages that circulating water flow rate of the low backpressure condenser is independently controlled, the circulating water flow rate of the high backpressure condenser is not influenced; by virtue of a calculation formula provided by the invention as well as the measuring points and a valve control system, the low backpressure side condenser is vacuum and does not enter a blockage backpressure region, and heat rate of a steam turbine is reduced; and due to influence of the circulating water bypasses, water inlet temperature of circulating water at the high backpressure side condenser is relatively low, and high backpressure side exhaust temperature is indirectly lowered, so that the heat rate of the steam turbine is further reduced.

The invention discloses a heat recovery system with a plurality of stages of hybrid heaters. Specifically, the heat recovery system comprises a BEST machine, five high-pressure heaters, five low-pressure heaters, the two to five hybrid heaters, boosting pumps and a condensate pump; each hybrid heater is configured with the corresponding boosting pump; the condensate pump is positioned between thelow-pressure heaters and a steam condenser; extraction steam of the first high-pressure heater is from a main steam turbine; the extraction steam of the second high-pressure heater to the fifth high-pressure heater is from the BEST machine; steam sources of the hybrid heaters are all from the BEST machine, wherein the steam source of the last stage hybrid heater is from the exhaust steam of the BEST machine; the extraction steam of the five low-pressure heaters is from the main steam turbine; and the last stage hybrid heater is connected with one of the low-pressure heaters, and the water supply of the last stage hybrid heater is from the low-pressure heater. According to the heat recovery system with the plurality of stages of deaerators, the circulating efficiency of the system is improved; the superheat degree of the steam is fully utilized; the project cost is reduced; the cold end loss of the steam is reduced; and the heat recovery system with the multiple stages of deaerators isparticularly suitable for the situation that the steam extracting steam of a plurality of heaters are close to the saturation pressure of the steam, and the feed water flow is large.

The invention relates to the field of textile technology. The purpose is to provide a two-for-one twister with long service life and automatic braking of broken wires, including a winding device, a wire breaking detection device, a yarn collector and a twisting device arranged on the frame from top to bottom; After successively passing through the twisting device, the yarn collector, and the broken wire detection device, it is wound on the winding device; the twisting device includes a twisting mechanism and a driving mechanism for driving the action of the twisting mechanism; the driving mechanism includes a The second transmission rod on one side of the first transmission rod is installed on the frame through the second bearing; the lower end of the second transmission rod is connected to the rotating shaft of the twisting motor through a magnetic clutch transmission assembly. The invention can quickly disconnect the power connection between the driving mechanism and the twisting mechanism, reduces the load on the driving mechanism during braking, lays the foundation for the emergency stop of the twisting mechanism, and greatly prolongs the operating time of the driving mechanism. service life.
