Description

Technical Field

[0001] The invention relates to the technical field of municipal engineering, in particular to a municipal engineering cross-flow steam generator. Background Art

[0002] Municipal engineering refers to the civil engineering, pipeline, and equipment installation projects of urban roads, public transportation, water supply, drainage, gas, heat, gardening, sanitation, sewage treatment, garbage disposal, flood control, underground public facilities, and ancillary facilities.

[0003] The equipment often used in municipal engineering is the cross-flow steam generator. The cross-flow steam generator is a highly efficient and energy-saving steam generating equipment. Compared with the traditional steam generator, it adopts advanced design and technology, with smaller volume and higher thermal efficiency. Its unique fluid dynamics design makes the heat transfer more uniform and improves the steam generation efficiency.

[0004] The patent with patent announcement number CN212252561U discloses an automatic water-adding electric heating steam generator, including a support, a heating tank, a water inlet, a first electric heating wire, a constant pressure valve, a steam pipe, a float, a pressure relief port and a pressure gauge. The support is located at the bottom of the entire device, and a heating tank is provided at the top of the support. The first heating wire and a float are provided inside the heating tank. The top of the heating tank is provided with a water inlet and a constant pressure valve, and the top of the constant pressure valve is provided with a steam pipe. A pressure relief port and a pressure gauge are provided on one side of the heating tank. In the invention, a float is provided. When the water level is too low, the piston is pulled down by the float to add water to the heating tank to prevent the heating tank from being damaged by the low water level. When the water volume is sufficient, the piston closes the water outlet under the push of the float to prevent the internal pressure of the heating tank from being too high due to excessive water volume. A constant pressure valve is designed to allow the steam to stay in the heating tank for a period of time to ensure the high temperature of the steam.

Through the arrangement of the above structure, the resetting of the spring 17 will drive the fixed block 14, the L-shaped knocking block 15, and the resistance block 16 to reset, so that the L-shaped knocking block 15 knocks the arc scraper ring 11, so as to more effectively scrape off the dirt attached to the inner wall of the cross-flow steam generator body 1, including hard and stubborn dirt, thereby ensuring the operation efficiency of the equipment.

The long rod 10 moves, thereby driving the spring 17 to stretch. When the resistance block 16 does not resist the protrusion 18, the spring 17 will reset. The reset of the spring 17 will drive the fixed block 14, the L-shaped knocking block 15, and the resistance block 16 to reset, so that the L-shaped knocking block 15 knocks the arc-shaped scraper ring 11, and more effectively scrapes off the dirt attached to the inner wall of the cross-flow steam generator body 1, including hard and stubborn dirt, to ensure the operation efficiency of the equipment; the movement of the long rod 10 drives the fixed rod 66 to move, and the movement of the fixed rod 66 drives the extrusion ring 67 to move. When the extrusion ring 67 moves to the inside of the arc groove 62, it will squeeze the annular pressing key 64, so that the liquid storage tank 63 sprays the cleaning agent from the nozzle 65, thereby neutralizing the acidic dirt, reducing the formation of scale, and reducing its corrosiveness to the equipment materials.
