Vacuum phase-change hot water boiler

Abstract

This utility model relates to the field of vacuum phase change hot water boiler technology, and discloses a vacuum phase change hot water boiler, including a vacuum phase change hot water boiler body. A water inlet is provided on the left side of the vacuum phase change hot water boiler body, and a water inlet pipe is installed inside the water inlet. This vacuum phase change hot water boiler, through the setting of an automatic pressure relief mechanism, ensures that during operation, if a combustion structure malfunction causes the heat transfer medium water to be overheated, generating a large amount of steam and causing a sharp increase in the boiler's internal pressure, a pressure gauge installed on the top of the vacuum phase change hot water boiler body detects the internal pressure. If the pressure is too high, the pressure gauge transmits a signal to a PLC controller on one side. The PLC controller then controls the pressure relief valve on the surface of the top pressure relief port to open and controls the alarm light to sound an alarm, thereby achieving the effect of automatic pressure relief and early warning, preventing safety accidents caused by excessive pressure.

Description

Technical Field

[0001] This utility model relates to the field of vacuum phase change hot water boiler technology, and in particular to a vacuum phase change hot water boiler. Background Technology

[0002] Vacuum phase change hot water boilers, also known as vacuum boilers, are a special type of hot water boiler. Their core working principle lies in creating a negative pressure vacuum environment inside a sealed boiler body. Within this environment, heat transfer water is filled and heated, and then the heat energy is transferred to the water requiring heating through the evaporation and condensation processes of the heat transfer water.

[0003] A vacuum phase change hot water boiler disclosed in announcement number CN222438186U includes a boiler body with a base fixedly connected to its bottom. A water outlet pipe is fixedly connected to one side of the boiler body, and multiple water inlet branch pipes are fixedly connected to the surface of the water outlet pipe. A valve is fixedly connected to the other end of each water inlet branch pipe. A flange is fixedly connected to one end of the valve, and a connecting sleeve is fitted onto the surface of flange one. The other end of the connecting sleeve is fitted into flange two on the surface of the main water inlet pipe. Bolts pass through flange one, flange two, and the connecting sleeve to connect them. Multiple rubber strips are inserted into both sides of the connecting sleeve, clamping the bolts. The advantages are: the multiple water inlet branch pipes and valve facilitate control of the flow rate and velocity of the water inlet branch pipes, increasing the heat exchange area and heating speed; and the connecting sleeve improves the sealing of the water pipe connections.

[0004] While the aforementioned patent achieves the goal of setting up multiple inlet branch pipes and valves to facilitate control of the flow rate and velocity of the inlet branch pipes, thereby increasing the heat exchange area and heating speed, and incorporating connecting sleeves to improve the sealing of the water pipe connections, the device lacks a pressure warning function. When the combustion system malfunctions or the heating element becomes uncontrolled, the heat transfer medium may be overheated, generating a large amount of steam and causing a sharp increase in furnace pressure. If the pressure continues to rise without release, it will exert enormous pressure on the boiler's pressure-bearing components, threatening equipment and personnel safety. Utility Model Content
