A plate heat exchange method for a high-efficiency energy-saving boiler

Abstract

The invention relates to the technical field of heat exchangers, in particular to a plate heat exchange method for a high-efficiency energy-saving boiler, including a boiler, the top of the boiler is fixedly connected with a gas guide valve, and the outer end of the gas guide valve is fixedly connected with a filter box, and the outer end of the filtration box is fixedly connected with a through pipe. The plate heat exchanger of the high-efficiency and energy-saving boiler adopts symmetrically distributed semicircular notches on the outside of the plates, and movably connects symmetrically distributed limit rods inside the plate outer plate openings, and the plate The top of the top is movably connected to the airtight pressure plate, and at the same time, the high-pressure casing and the cover are movably connected to the outside of the limit rod, and the high-voltage casing and the cover are used to provide a sealed space for the plate, thereby ensuring that the device will not run during operation. It is polluted by the dust in the unconnected air, which solves the problem that the previous device is exposed and the gasket inside the plate is easily oxidized.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a plate heat exchange method for high-efficiency and energy-saving boilers. Background technique [0002] With the rapid development of social industry and manufacturing industry, people's demand for temperature control has gradually increased, especially the high-temperature treatment of raw materials inside boilers for power generation or industrial use, so a high-efficiency energy-saving boiler plate heat exchange is required device. [0003] There are many types of plate heat exchangers on the market, but most heat exchangers expose the plates to the outside. During use, the plates inside the heat exchanger tend to accumulate dust when they are not closed, and Existing plate heat exchangers use exposed settings, which will lead to low airtightness of the device and easy leakage. Over time, the gaskets inside the plates will be oxidized. At the same time, the existing...

Problems solved by technology

[0003] There are many types of plate heat exchangers on the market, but most heat exchangers expose the plates to the outside. During use, the plates inside the heat exchanger tend to accumulate dust when they are not closed, and Existing plate heat exchangers use exposed settings, which will lead to low airtightness of the device and easy leakage. Over time, the gaskets inside the plates will be oxidized. At the same time, the existing plate heat exchangers are processing hot steam. Among them, the plates inside the plate heat exchanger are easily affected by the external environment, which will cause a large amount of liquid inside the device. Excessive liquid accumulation inside the device will lead to poor heat transfer capability of the device. In addition, the existing plate heat exchanger The converter usually uses an independent heat conversion device for heat transfer. During the long-term heat transfer process, the temperature of the plate will gradually rise, which will lead to a decrease in the working efficiency of the device. Therefore, we propose a high-efficiency energy-saving boiler plate heat exchanger
