In order to avoid the loss and waste of heat at the tail end, a heat absorption device is installed at the tail end of the steam boiler to absorb and utilize the heat. When existing heat absorption devices are in use, they mostly connect the heat absorption chamber to the water tank through heat conduction pipes, so as to guide the heat at the tail end to the cold water, heat the cold water, and then use the hot water.
[0003] CN215892319U discloses a tail heat absorption device for a steam boiler, including a shell. One end of the shell is fixedly provided with an air inlet, and the other end of the shell is fixedly provided with an air outlet. A water inlet is opened at the top of the shell, and a water outlet is opened at the bottom of the shell. A first cold water chamber is fixedly provided on the inner wall of the shell. A second cold water chamber is provided inside the first cold water chamber. Several connecting pipes are fixedly provided through the upper and lower parts of the second cold water chamber. The several connecting pipes are fixedly connected to the first cold water chamber. Several heat conduction pipes are fixedly provided on the side walls of the first cold water chamber and the second cold water chamber. A stirring mechanism is rotatably provided on the inner side wall of the shell. A rotating motor is fixedly provided at the top of the shell.
[0004] In existing devices, steam heats water flow and is then filtered before being discharged. However, the steam contains a large amount of water, which causes water loss. Therefore, we propose a tail-end heat absorption device for steam boilers. Utility Model Content
[0005] The purpose of this invention is to provide a tail-end heat absorption device for a steam boiler, which solves the existing problems.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A tail-end heat absorption device for a steam boiler includes a steam condensation tank. A steam heat conduction pipe is fixedly installed on the left side of the steam condensation tank, a steam boiler connecting pipe is fixedly installed on one side of the steam heat conduction pipe, a water storage pipe is fixedly installed on the outer side of the steam heat conduction pipe, a water pump is fixedly installed on the front side of the steam condensation tank, a water supply pipe is fixedly installed at the input end of the water pump, a cooling pipe is fixedly installed on the top of the steam condensation tank, a water inlet pipe is fixedly installed at the output end of the water pump, the output end of the water inlet pipe is fixedly installed at the input end of the cooling pipe, a water outlet pipe is fixedly installed at the output end of the cooling pipe, and the output end of the water outlet pipe is fixedly installed at the input end of the water pump.
[0008] As a further improvement to the above solution, condensate discharge guide plates are fixedly installed on the inner walls of the front and rear sides of the steam condensation box, two condensate discharge pipes are fixedly installed on the right side of the steam condensation box, a water inlet pipe is fixedly installed on one side of the condensate discharge pipe, and the output end of the water inlet pipe is fixedly installed at the input end of the water pump.
[0009] As a further improvement to the above solution, a water inlet pipe is fixedly installed at the output end of the water pump, and the output end of the water inlet pipe is fixedly installed inside the water storage pipe.
[0010] As a further improvement to the above solution, a hot water discharge pipe is fixedly installed on the inner side of the water storage pipe, and a solenoid valve is fixedly installed on the outer side of the hot water discharge pipe.
[0011] By adopting the above technical solution, the solenoid valve can be opened after the water inside the water storage pipe is heated to a certain temperature, so that the water inside the water storage pipe can be discharged.
[0012] As a further improvement to the above solution, a motor is fixedly installed on the left side of the steam condensation box, a lead screw is fixedly installed at the output end of the motor, a limit rod is fixedly installed on the inner side of the steam condensation box, and a cleaning scraper is fixedly installed on the outer side of the limit rod, with the cleaning scraper slidably disposed on the outer side of the limit rod.
[0013] By adopting the above technical solution, the cleaning scraper can clean the top inner wall of the steam condenser. When the device is not in use, it can keep the inside of the steam condenser clean and prevent corrosion and rust.
[0014] As a further improvement to the above solution, both the steam heat pipe and the cooling pipe are made of thermally conductive materials.
[0015] As a further improvement to the above solution, the top of the steam condensation box is triangular in shape, and the condensate discharge guide plate is inclined.
[0016] By adopting the above technical solution, the water pump transmits water flow through the water inlet pipe to the inner cavity of the water storage pipe for heating. Since the cooling pipe absorbs more heat when cooling the steam condenser, the water temperature inside the cooling pipe can be increased. The water can then enter the water pump through the outlet pipe, and the higher temperature water is transmitted to the water storage pipe through the water inlet pipe. This allows the device to have a high heat utilization rate, and the steam will not be wasted after discharge. The inclined condensate discharge guide plate allows the condensed water droplets to slide into the inner side of the condensate discharge pipe.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] (1) The tail heat absorption device of the steam boiler of this utility model connects the steam boiler connecting pipe to the tail of the steam boiler. The steam can enter the inner side of the steam heat conduction pipe. The steam heat conduction pipe is made of heat conduction material, which can heat the water flow inside the water storage pipe. The steam will move upward during the flow. The water supply pipe can provide water to the water pump. The water pump conducts the water flow to the cooling pipe through the water inlet pipe. The cooling pipe can cool the top of the steam condenser. The steam condenses into water droplets when it encounters the cold. The water flow into the pipe can transmit the water droplets to the inner cavity of the water storage pipe for heating.
[0019] (2) The tail heat absorption device of the steam boiler of this utility model absorbs more heat when the cooling pipe cools the steam condenser, which can raise the temperature of the water flow inside the cooling pipe, allowing the water flow to enter the water pump through the outlet pipe, and the higher temperature water flow is transmitted to the storage through the water flow inlet pipe.

[0033] In this embodiment, the top of the steam condenser 1 is triangular, and the condensate discharge guide plate 10 is inclined.
[0034] The implementation principle of the tail heat absorption device of a steam boiler in this embodiment is as follows: the steam boiler connecting pipe 3 is connected to the tail of the steam boiler, and the steam can enter the inner side of the steam heat conduction pipe 2.

This allows the device to have a high heat utilization rate and prevents steam from being wasted after discharge.
