Method for recovering waste heat of thermal power plant and heating and supplying heat to hot water in a stepping way

The invention discloses a method for recovering the waste heat of a thermal power plant and heating and supplying heat to hot water in a stepping way. In the method, low-temperature heat-net return water is firstly mixed with circulating cooling water positioned on an outlet of a cooling condenser or exchanges heat with the circulating cooling water positioned on the outlet of the cooling condenser to be increased in temperature and then sequentially delivered into an each-step vapour absorption type heat pump and a vapor-water heat exchanger in a series connection way to be gradually heated to be increased in temperature to heat supplying temperature and finally discharged through a water supplying pipeline; the circulating cooling water absorbs the waste steam condensation heat of a steam turbine in the cooling condenser, then one path of the circulating cooling water is directly mixed with the low-temperature heat-net return water or heats the low-temperature heat-net return water through the heat changer, the other path of the circulating cooling water is delivered into an each-step absorption type heat pump unit to be used as a low-order heat source of the absorption type heat pump unit, and the redundant heat of the circulating cooling water is discharged to the environment through a cooling tower. The invention uses the steam extraction of the steam turbine as a driving heat source of the absorption type heat pump so that the low-temperature heat-net return water is heated in a stepping way, thereby reducing the effective energy loss; the waste heat of the discharged steam of the steam turbine is sufficiently recovered in a direct heating way and an absorption type heat pump temperature increasing heating way, therefore, the comprehensive energy usage efficiency of the thermal power plant is enhanced.

An improved pulsatory slit apparatus to be connected for a dental hygiene. Supply line valves to be shutoff before connecting the devices. By disconnecting cold water conduit of a faucet of a sink from a domestic cold water supply line valve in a bathroom and reconnecting it to 19B, and by connecting the valve to 18A as shown in FIG. 1, it becomes an operative device as shown in FIG. 2. For a combination of hot and cold water, by disconnecting the cold water supply line valve as previously stated and by disconnecting the hot water conduit of the faucet from the hot water supply line valve in a bathroom and reconnecting the cold water connector to a top right side straight end 19B of an apparatus and the hot water connector to a top left side straight end 19B of the apparatus as shown in FIG. 3, this process completes a connection of the faucet and the apparatus. To complete the connection of the apparatus and the supply lines it requires two conduits of the same size hexagonal or of similar configurational nuts at the four ends of the conduits. One conduit connects to the cold water supply line valve and the other end of the conduit connects to the bottom right side straight end 19B of the apparatus. The second conduit connects to the hot water supply line valve and the other end of the conduit connects to a bottom left side straight end 19B of the apparatus as shown in FIG. 3. This process completes the connections of the supply lines of the apparatus and it becomes an operative device as shown in FIG. 4. An open-shutoff orifice valve directs the water to a hand held cylindrical device. The hand held cylindrical device having a pressure control valve assembly and the assembly having an off-on pressure control dial. A nipple of a slit orientation is attachable to the hand held cylindrical device. The hand held cylindrical device with the pressure control dial at fingertip redirects the water under pressure to the nipple for users' teeth and gums. The nipple provides the users strong pulsatory slits of thousands of tiny pulses, not just droplets as described in the prior arts. The pressure control dial let the users control the desirable pressure for comfortable use of the dental hygiene pulsatory slit apparatus.

In-hole drilling tool integrating drilling, slotting and punching coal seam and using method thereof

The invention discloses an in-hole drilling tool integrating drilling, slotting and punching a coal seam and a using method thereof. The in-hole drilling tool comprises a water supple device or an air supple device, a high-pressure sealing drill pipe, a slotting and punching valve and a drill bit. The water supply device and the air supply device are connected with the high-pressure sealing drill pipe at an orifice. The slotting and punching valve is installed between the high-pressure sealing drill pipe and the drill bit. The in-hole drilling tool is essentially used for drilling and anti-reflective outburst eliminating after drilling of soft outburst coal seam. The using method is as follows: after the drilling construction is finished, a water supplier with a pressure release valve is used for starting a high-pressure pumping station to improve the pressure and the flux for water supply; high-pressure water current at the pumping station drives the slotting and punching valve to act for closing an axial liquid passage and opening a radial liquid passage; and high-pressure jet current realizes slotting or punching through a cutting nozzle or a punching nozzle. The invention has novel design and easy operation, is safe and reliable, improves the outburst elimination efficiency and realizes the integrated operation of drilling, slotting or punching and outburst eliminating.
