[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] like Figures 1 to 3 As shown, a steam condenser is arranged above a steam water pool 1 and comprises a condensation cylinder 2 , wherein the condensation cylinder 2 is mainly used for condensing waste steam entering the condensation cylinder 2 .

[0022] A cover plate 3 is provided on the top of the steam pool 1 , and a through hole 4 is provided at the center of the cover plate 3 , so that the waste steam in the steam pool 1 can enter the inner cavity of the condensation cylinder 2 .

[0023] The condensing cylinder 2 is placed above the steam pool 1. The diameter of the condensing cylinder 2 is 1m, and the height of the condensing cylinder 2 is 2.2m. A water inlet assembly 5 is provided at the top center of the condensing cylinder 2, and the water inlet assembly 5 includes a top plate 12, a water inlet main pipe 13, and a water inlet branch 14. The top plate 12 is provided on bosses 15 uniformly distributed on the top of the inner side wall of the condensing cylinder 2. The provision of the bosses 15 not only bears the weight of the top plate 12 but also makes the top plate 12 more stable. A water pipe installation hole 16 is provided at the center of the top plate 12. The bottom end of the water inlet main pipe 13 passes through the water pipe installation hole 16 and extends into the inner cavity of the condensing cylinder 2. Several water inlet branches 14 are evenly distributed at the bottom end of the water inlet main pipe 13 and are connected to the water inlet main pipe 13. Several spray ports 17 are evenly provided on the water inlet branches 14. The spray ports 17 are mainly used to spray the liquid condensed on the grate 8, increase the liquid content flowing into the steam water pool 1, and save water consumption in the subsequent production of autoclaved aerated concrete. In addition, the water inlet component 5 is selected to accelerate the steam condensation effect, make the heat exchange more sufficient, and improve the waste heat recovery efficiency. An air inlet 6 is provided at the bottom of the condensing cylinder 2. The air inlet 6 is connected to the through hole 4. The existence of the air inlet 6 facilitates the waste steam to enter the inner cavity of the condensing cylinder 2 on the one hand, and facilitates the liquid condensed on the grate 8 to flow into the steam water pool 1 for subsequent production on the other hand. Two air outlet pipes 7 are evenly distributed along the circumferential direction at the top of the side wall of the condensing cylinder 2, and the residual waste steam enters the atmosphere along the air outlet pipes 7. The inner cavity of the condensing tube 2 is evenly distributed with a number of grates 8 from top to bottom, and the inner cavity side wall of the condensing tube 2 is evenly distributed with a number of limit blocks 10 corresponding to the grates 8 from top to bottom along the circumferential direction. One side of the limit block 10 fits the inner cavity side wall of the condensing tube 2, and the other side of the limit block 10 is provided with a slot 11, and the slot 11 is engaged with the outer wall of the grate 8. The arc size of the slot 11 is consistent with the arc size of the grate 8. The setting of the slot 11 is convenient for engaging the grate 8, making the grate 8 more stable in the inner cavity of the condensing tube 2. The spacing size between the several grates 8 is 25 cm. Selecting several grates 8 allows the waste steam to condense into liquid after encountering the grate 8 and then fall into the steam pool 1. The use of several grates 8 can make the waste steam achieve multiple condensation, improve the condensation effect, and improve the utilization rate of the waste steam. The grate 8 is evenly provided with a plurality of circular holes 9. The diameter of the circular holes 9 is 15 mm, and the interval between the circular holes 9 is 40 mm. The liquid condensed on the grate 8 flows from the circular holes 9 into the adjacent grate 8 or into the steam pool 1.

[0024] The utility model adopts a steam pool 1 and a condensing cylinder 2, and has a simple structure. The condensing cylinder 2 is placed above the steam pool 1. Waste steam released from the steam pool 1 in the production of autoclaved aerated concrete enters the inner cavity of the condensing cylinder 2, is condensed, and then returns to the steam pool 1 to become hot, thereby saving the cost of cold water heating and also saving the amount of water used in the production of autoclaved aerated concrete, and achieving the purpose of waste gas recovery.

[0025] The working process of the utility model is as follows:

[0026] Waste steam from the production of autoclaved aerated concrete enters the inner cavity of the condensing tube 2 from the steam pool 1 along the through hole 4. The waste steam condenses after encountering the multi-layer grates 8. The water inlet main pipe is connected to the external water source, and the water source is sprayed to the grates 8 from a plurality of spray ports 17, so that more condensed liquid flows from the grates 8 to the adjacent grates 8 or into the steam pool 1. The water in the steam pool 1 can be used for subsequent autoclaved aerated concrete production through the pumping pipe.

[0027] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above implementation modes. The implementation modes can still be changed within the knowledge scope of ordinary technicians in the field. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
