When the invention is used, after foam plastic foaming molding is finished, redundant steam is introduced into the waste heat recovery pipe 1, the steam enters the communication groove 6 through the waste heat recovery pipe 1 under the pressure effect, the steam entering the communication groove 6 can continuously enter the hollow groove 5, the steam entering the hollow groove 5 can be blocked by the fan blade 9 rotationally connected in the hollow groove 5, under the condition, the pressure of the steam is higher than the external atmospheric pressure, compared with the external atmospheric pressure, the steam before release has pressure potential energy, under the pressure difference effect of the steam and the external atmospheric pressure, the steam blocked by the fan blade 9 in the hollow groove 5 can push the fan blade 9 to rotate, and finally is released from the other communication groove 6 along with the rotation of the fan blade 9;
in the above process, by means of the pressure difference between the pressure of the high-temperature high-pressure steam and the external atmospheric pressure, the fan blade 9, the mounting sleeve 8 and the transmission shaft 7 are driven to rotate by taking the pressure difference as power, the transmission shaft 7 is driven to work in a manner of driving the transmission shaft 7 to convert the pressure potential energy existing in the high-temperature high-pressure steam due to the pressure difference with the external atmospheric pressure into the mechanical energy of the transmission shaft 7, wherein the mechanical energy is mainly the rotational kinetic energy;
when the transmission shaft 7 rotates, one end of the transmission shaft 7 in the water supply pump 12 drives the screw rod 16 and the thread teeth 17 on the screw rod 16 to rotate, and as the thread teeth 17 on the two screw rods 16 are in meshed connection, the contact of the side walls of the thread teeth 17 of the meshed part can be regarded as a sealing structure, so that the cooling water entering the water supply pump 12 can be intercepted in the gaps among the screw rods 16, the thread teeth 17 and the meshing chamber 13 and the gaps among the two thread teeth 17 by means of the meshing effect of the two thread teeth 17 and the sealing structure of the outer side walls of the thread teeth 17 and the inner side walls of the meshing chamber 13, and the intercepted cooling water is pushed to the middle direction along with the rotation of the transmission shaft 7, the rotating shaft 15, the screw rod 16 and the thread teeth 17, and the cooling water is extruded and discharged from the guide pipe 21 under the pressure effect;

after the cooling water enters the heat exchange groove 11 in the heating box 10, the waste heat recovery pipe 1 can be used as a heat conduction medium, so that the cooling water can exchange heat with steam through the side wall of the waste heat recovery pipe 1, the cooling water flowing through the heat exchange groove 11 can be heated, and the heated cooling water can be used for other purposes, so that the waste heat recovery of high-temperature high-pressure steam is realized;
because the high-temperature high-pressure steam is continuously fed into the waste heat recovery pipe 1, in order to avoid the too fast release of the pressure potential energy and ensure that the pressure potential energy sufficiently pushes the fan blades 9 to rotate, the invention arranges the baffle plate 2, the mounting hole 3 and the pressure relief valve in the waste heat recovery pipe 1, and the pressure is accumulated by the pressure relief valve to ensure that the fan blades 9 are sufficiently driven to rotate each time the pressure potential energy is released, so that new cooling water is injected into the heat exchange groove 11 by the water feeding pump 12, and the release speed of the pressure potential energy is slowed down by the pressure relief valve, so that the greater utilization of the pressure potential energy is realized;
since the flow rate of the cooling water in the heat exchange tank 11 is directly related to the speed of the water supply pump 12 for injecting new cooling water into the heat exchange tank 11 through the conduit 21, and the speed of the water supply pump 12 for injecting new cooling water into the heat exchange tank 11 is directly related to the release of the pressure potential energy at the power box 4, the higher the flow rate of the high-temperature high-pressure steam fed into the waste heat recovery pipe 1, the faster and more the pressure energy released at the power box 4, the higher the flow rate of the cooling water in the corresponding heat exchange tank 11, and the faster the flow rate;
the advantage of this arrangement is that the higher the flow rate of the high-temperature high-pressure steam in the waste heat recovery pipe 1, the higher the temperature will be, and the larger the temperature difference between the high-temperature high-pressure steam and the cooling water will be, so the higher the waste heat recovery efficiency will be, the lower the flow rate of the high-temperature high-pressure steam in the waste heat recovery pipe 1 will be, and the smaller the temperature difference between the high-temperature high-pressure steam and the cooling water will be, and the lower the waste heat recovery efficiency will be, on the basis of the above, in order to make the cooling water more capable of absorbing the heat of the high-temperature high-pressure steam, the higher the cooling water flow rate and the higher the flow rate will be when the flow rate of the high-temperature high-pressure steam in the waste heat recovery pipe 1 is required, and the lower the cooling water flow rate and the lower the flow rate will be when the flow rate of the high-temperature high-pressure steam in the waste heat recovery pipe 1 is smaller, while the invention is fully adapted to this point;
the heat conduction plate 23, the notch groove 24 and the flow guide cavity 25 are arranged, so that the path length of high-temperature and high-pressure steam passing through the waste heat recovery pipe 1 is greatly prolonged, the contact area between the inner side wall of the waste heat recovery pipe 1 and the high-temperature and high-pressure steam is indirectly increased by means of the heat conduction plate 23, the waste heat recovery efficiency of cooling water in the heat exchange groove 11 is further improved, the flow guide plate 26 in the heat exchange groove 11 is arranged, and the waste heat recovery efficiency of heat energy in the high-temperature and high-pressure steam is further improved by prolonging the path length of the cooling water passing through the heat exchange groove 11;
the flow direction of the cooling water in the heat exchange groove 11 is from the lower spiral to the upper spiral, the flow direction of the high-temperature high-pressure steam in the waste heat recovery pipe 1 is from the upper spiral to the lower spiral, the flow directions of the cooling water and the high-temperature high-pressure steam are opposite, the cooling water is subjected to cold and heat exchange between the waste heat recovery pipe and the steam, and is heated and warmed, and the steam is cooled and warmed in the process, so that the cooling water is gradually warmed along the flow directions along the respective flow directions, the temperature is gradually increased from the lowest to the highest, the steam is gradually cooled along the flow directions, and the temperature is gradually decreased from the highest to the lowest;
in the waste heat recovery of steam, the premise of cold and heat exchange between cooling water and steam is that the temperature difference exists between the cooling water and the steam, and the flow direction of the cooling water is opposite to the flow direction of the steam, so that when the cooling water passes through the waste heat recovery pipe 1 and exchanges cold and heat with the steam in the heat exchange groove 11, the temperature difference exists stably at all positions along the flow direction, the cooling water can always absorb the waste heat of the steam, the whole waste heat recovery efficiency and effect are fully ensured and improved, and the cooling water can be heated to a higher temperature.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
