Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of condensate recovery equipment, in particular to a boiler condensate recovery mechanism. Background Art
[0002] A steam boiler is a type of boiler designed specifically for producing steam. During its operation, it produces a large amount of steam. When this steam rises and encounters a cold object, it forms condensate. This condensate has a high recycling value and can be recycled through specialized recycling facilities.
[0003] Announcement number CN218097280U discloses a condensate recovery mechanism for a steam boiler, comprising a housing, an air intake pipe, and a metal arc-shaped cover. The top of the housing is bolted to the metal arc-shaped cover, and the bottom of the metal arc-shaped cover is fixed with metal cones for condensing water droplets at equal intervals via threaded grooves. A water hopper is bolted to the interior of the housing, and a float is provided on the top of the water hopper. A ventilation box is bolted to the top of the housing, and an exhaust fan is installed inside the ventilation box via a mounting bracket. The utility model can draw steam generated by the steam boiler into the housing. When the steam contacts the low-temperature metal arc-shaped cover, it is converted into condensate, which is temporarily stored in the housing, achieving the purpose of condensate recovery. The provision of the water hopper and float can prevent the steam from flowing out with the condensate.
[0004] Most of the common boiler condensate recovery mechanisms on the market only consider the separation of steam and condensate, and do not fully consider other values such as the heat of recovered condensate. Utility Model Content
[0005] The purpose of the utility model is to provide a boiler condensate recovery mechanism to solve the deficiencies in the above-mentioned prior art.
[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a boiler condensate recovery mechanism, comprising a box body and a water storage tank, a boiler is fixedly installed inside the box body, the interior of the boiler and the interior of the water storage tank are connected by a water supply pipe, an air outlet pipe is connected to the top end of the boiler, the other end of the air outlet pipe is connected to a connecting pipe, the other end of the connecting pipe is connected to a heat exchanger through a hose, a float is fixedly connected to the heat exchanger, the float floats on the water surface in the water storage tank, and the heat exchanger is located below the water surface.
[0007] Furthermore, the heat exchanger includes a water inlet pipe, several thin tubes and a water outlet pipe, the hose is connected to one end of the water inlet pipe, the other end of the water inlet pipe is connected to the several thin tubes, and the other end of each of the thin tubes is connected to the water outlet pipe.
[0008] Furthermore, the heat exchanger is located 10-30 mm below the water surface.

[0010] Furthermore, a plurality of support blocks are fixedly connected to the bottom end of the boiler, and the other ends of the support blocks are fixedly connected to the bottom end of the cavity inside the box.
[0011] Compared with the prior art, the beneficial effect of the present invention is that, by setting a water supply pipe, the water in the water tank is pumped into the boiler inside the box body, the steam generated by the boiler is discharged from the box body through the exhaust pipe, and the steam is transported to the heat exchanger through the connecting pipe. The heat exchanger is located in the water, and the steam condenses in the process of passing through the heat exchanger. In this process, the heat exchange formed by the steam and the water in the water reservoir increases the initial temperature of the water in the water reservoir, so that the energy consumption when the boiler is working is reduced, and the condensed water is fully recovered and reused, thereby reducing heat loss and improving economy. By setting a hose and a float, the heat exchanger can adjust its position in real time according to the change of the water level in the water tank, so that the depth of the heat exchanger from the water surface is always consistent and does not change with the change of the water level.

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0019] Please refer to Figures 1-3 The boiler condensate water recovery mechanism provided by the embodiment of the utility model, including box 1 and water storage tank 2, the fixed installation of box 1 inside has boiler 3, and the inside of boiler 3 is communicated with the inside of water storage tank 2 through water supply pipe 4, and the top end of boiler 3 is provided with the communication of outlet pipe 5, and the other end of outlet pipe 5 is communicated with the communication pipe 6, and the other end of communication pipe 6 is communicated with the heat exchanger 8 through the hose 7, and the heat exchanger 8 is fixedly connected with the float 9, and the float 9 floats on the water surface in water storage tank 2, and the heat exchanger 8 is below the water surface.
[0020] The heat exchanger 8 includes the water inlet pipe 12, several thin tubes 13 and the water outlet pipe 14, and the hose 7 is communicated with one end of the water inlet pipe 12, and the other end of the water inlet pipe 12 is communicated with several thin tubes 13, and the other end of each thin tube 13 is communicated with the water outlet pipe 14, and the steam generated by the work of boiler 3 flows into the water inlet pipe 12 in the heat exchanger 8 through the hose 7, and then is shunted through several thin tubes 13, and the function of thin tube 13 is to increase the contact area and accelerate the condensation speed, and in this process, the heat exchange is formed between the steam and the water in water storage tank 2, the steam is condensed into condensate water, and the initial temperature of the water in water storage tank 2 is improved, so that the energy consumption of boiler 3 can be reduced when working, and finally the condensate water is converged and flows into water storage tank 2 from the water outlet pipe 14, the condensate water is fully recovered, reused, heat loss is reduced, and economic efficiency is improved.
[0021] The bottom end of boiler 3 is fixedly connected with several supporting blocks 11, and the other end of supporting block 11 is fixedly connected to the bottom end of the cavity inside box 1, for supporting boiler 3, and box 1 can play the effect of heat preservation for boiler 3, and the working efficiency of boiler 3 is improved.
[0022] When the heat exchanger 8 is located at a relatively shallow position below the water surface, the water in water storage tank 2 that flows into the heat exchanger 8 and the communication pipe 6 is relatively small, so that the pressure in boiler 3 and the communication pipe 6 is relatively small, and the steam that is not fully condensed and discharged from the water outlet pipe 14 forms steam bubbles after entering the water in water storage tank 2, and the steam bubbles float to the water surface after a relatively short journey, so that the steam is relatively easy to escape; when the heat exchanger 8 is located at a relatively deep position below the water surface, the water in water storage tank 2 that flows into the heat exchanger 8 and the communication pipe 6 is relatively large, so that the pressure in boiler 3 and the communication pipe 6 is relatively large, and the steam that is not fully condensed and discharged from the water outlet pipe 14 forms steam bubbles after entering the water in water storage tank 2, and the steam bubbles float to the water surface after a relatively long journey, so that the steam is fully liquefied and not easy to escape. Therefore, the heat exchanger 8 in the present application is preferably located at 10-30mm below the water surface, which can timely release the pressure in boiler 3 and make the steam fully condensed. The setting of float 9 can make the heat exchanger 8 adjust the position in real time following the change of water level in water storage tank 2, so that the depth of heat exchanger 8 from the water surface always remains consistent and does not change with the change of water level.
[0023] Further, the depth of the heat exchanger 8 below the water surface can be fine-tuned by setting different floats 9 or the like.
[0024] The water supply pipe 4 is provided with a purifying device 10, which can filter out impurities in the extracted water, reduce the generation of scale during the operation of the boiler 3, and improve the operation efficiency.
[0025] Working principle: in use, the water in the water storage tank 2 is extracted into the water supply pipe 4 by using existing equipment such as a water pump, and the extracted water is filtered by the purifying device 10 provided on the water supply pipe 4 to filter out impurities and reduce the generation of scale during the operation of the boiler 3, thereby improving the operation efficiency. The extracted water is delivered to the boiler 3 through the water supply pipe 4, and after the delivery is completed, the boiler 3 starts to work. The steam generated by the operation of the boiler 3 is discharged into the communicating pipe 6 through the gas outlet pipe 5, and then delivered to the hose 7 through the communicating pipe 6, and then delivered to the heat exchanger 8. The heat exchanger 8 includes a water inlet pipe 12, a plurality of fine pipes 13, and a water outlet pipe 14. The hose 7 is in communication with one end of the water inlet pipe 12, the other end of the water inlet pipe 12 is in communication with the plurality of fine pipes 13, and the other end of each fine pipe 13 is in communication with the water outlet pipe 14. The steam generated by the operation of the boiler 3 flows into the water inlet pipe 12 of the heat exchanger 8 through the hose 7, and then is divided by the plurality of fine pipes 13. The fine pipes 13 serve to increase the contact area and accelerate the condensation speed. In this process, heat exchange occurs between the steam and the water in the water storage tank 2, the steam is condensed into condensed water, and the initial temperature of the water in the water storage tank 2 is increased, so that the energy consumption of the boiler 3 during operation is reduced. Finally, the condensed water flows into the water storage tank 2 from the water outlet pipe 14, the condensed water is fully recovered and reused, heat loss is reduced, and economic efficiency is improved. The float 9 provided on the heat exchanger 8 can adjust the position of the heat exchanger 8 in real time according to the change of the water level in the water storage tank 2, so that the depth of the heat exchanger 8 from the water surface remains consistent and does not change with the change of the water level.
[0026] The above only describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present application.
