Description

Technical Field

[0001] The present invention relates to the technical field of plate heat exchanger unit structures, and particularly to a fully intelligent plate heat exchanger unit. Background Art

[0002] The heat exchange unit is composed of heat exchangers, temperature control valve groups, steam traps, circulating pumps, electric control cabinets, bases, pipelines, valves, instruments, etc., and can be equipped with expansion tanks, water treatment equipment, variable frequency control of pumps, temperature control valves, remote communication control, etc., thus constituting a complete heat exchange station. The heat exchange unit has the advantages of standardized and modular design, complete configuration, convenient installation, high energy efficiency, compact structure, reliable operation, and simple and intuitive operation. It is the preferred high-efficiency energy-saving product. This product is suitable for heating, bathing, and air-conditioning systems in residential buildings, government agencies, factories, mines, hospitals, hotels, schools, etc. The integral heat exchange unit can be used for water-water exchange or steam-water exchange. This unit is composed of heat exchangers, circulating pumps, make-up water pumps, electric control cabinets, filters, bases, pipelines, valves, instruments, etc., and can be equipped with automatic constant pressure water supply devices, water treatment equipment, water tanks, variable frequency control of pumps, temperature control valves, remote communication control, etc., thus constituting a complete heat exchange station. This unit has the advantages of standardized and modular design, complete configuration, convenient installation, high energy efficiency, and has been widely used in systems such as district central heating, central air conditioning, domestic water, and industrial production process water. The integral heat exchange unit can be used for water-water exchange or steam-water exchange. The plate heat exchange unit is a type of heat exchange unit. Its characteristic is that it uses a plate heat exchanger. Under the same pressure loss condition, its heat transfer coefficient is three to five times higher than that of a tubular heat exchanger, and its floor area is one-third of that of a tubular heat exchanger. The heat recovery rate can be as high as over 90%. The plate heat exchange unit automatically and continuously converts the heat obtained from the primary network into domestic water and heating water required by users. That is, hot water enters the plate heat exchanger from the primary side inlet of the unit for heat exchange and then flows out from the primary side outlet of the unit;After the secondary side return water removes dirt through the filter, it enters the plate heat exchanger through the secondary side circulation pump for heat exchange, producing hot water at different temperatures for heating, air conditioning, floor heating, domestic water, etc. to meet the needs of users. The secondary water is filtered and decontaminated, then enters the heat exchanger through circulation, and is heated by steam or high-temperature water for heating. After the steam or high-temperature water enters the plate heat exchanger, it becomes condensate or high-temperature return water and returns to the heat source for the loop circulation of the primary and secondary heating systems. The make-up water pump pumps soft water into the system to maintain the constant system pressure. The characteristics of the plate heat exchange unit are as follows: First, this unit is optimized in design, with a reasonable layout, a compact structure, a small floor area, saving civil engineering investment, and being convenient for installation and maintenance. Second, the heat exchange unit adopts high-tech control means, with a high degree of intelligence and automation, being easy to operate and capable of unattended operation. Third, the heat exchange unit automatically replenishes water and automatically stabilizes the pressure. The make-up water pump can operate fully automatically and be manually controlled. Fourth, all the equipment components of the unit adopt high-quality products, and an efficient plate heat exchanger is selected, with high heat exchange efficiency, fast heat exchange, saving heat energy, convenient capacity expansion, and simple maintenance. The overall machine configuration is advanced and reasonable, and the control is perfect. The advantages of the plate heat exchange unit are as follows: First, the plate heat exchange unit can automatically turn on and off at a fixed time, and can achieve timed on-off control according to time, date, and different time periods. Second, the standby circulation pump and heat exchanger are automatically switched at a fixed time. The circulation pump is switched at a fixed time, and the circulation pump failure is automatically bypassed; the main plate heat exchanger and the standby plate heat exchanger are switched at a fixed time to maximize the service life of the system. Third, the industrial frequency and frequency conversion are automatically switched. The system collects temperature and pressure signals to control the frequency conversion of the circulation pump and the make-up water pump, and can automatically realize the frequency conversion switch between multiple circulation pumps and multiple make-up water pumps, as well as the automatic switch between frequency conversion and industrial frequency. Fourth, compared with the intelligent heat exchange unit, the plate heat exchange unit has a more concise, intuitive, and user-friendly human-machine interface, which is convenient for operation and use. By equipping with a touch screen, this system will have a good human-machine interface, which can display the complete system operation status, equipment status, and various thermal parameters. The operation parameters are centrally digitally displayed, and it can be controlled locally or connected to the central control room to facilitate remote monitoring by users. Fifth, the plate heat exchange unit has a powerful remote communication function, which can be connected to the upper computer either wired or wirelessly, can realize local area network control, and can also realize wireless monitoring. When a fault occurs, a wireless alarm signal will be immediately sent to the administrator's mobile phone for system maintenance in the first time;

[0003] However, there are certain drawbacks in the existing plate heat exchange units during use.

[0028] It should be noted that the present invention is a fully intelligent plate heat exchanger unit. When in use, cement is laid around the outer frame 1 of the base in the fully intelligent plate heat exchanger unit until the fixing piece 102 is completely submerged, but the height of the overflow prevention outer frame 101 on the base outer frame 1 cannot be exceeded. The fixing piece 102 on the outer side of the base outer frame 1 increases the contact area between the base outer frame 1 and the cement, making the fixation more firm. When the plate heat exchanger unit has been used for a long time or is damaged and needs to be replaced entirely, pull the pull rod 206 in the slide rail through hole 202 on the unit base 2 until reaching the card slot 203. Then, hold the right-angle auxiliary rod 207 by hand and insert the pull rod 206 into the card slot 203. Subsequently, tie a rope to the lifting handles 208 near both sides on the upper surface of the unit base 2, and use a crane to lift it for replacement. Place the new unit base 2 inside the base outer frame 1, pull the right-angle auxiliary rod 207 to let the pull rod 206 withdraw from the inside of the card slot 203, and let the round head pin 204 insert into the pin hole 103 on the inner side of the base outer frame 1 through the telescopic spring 205. Pull the pull ring 611 in the pipe fixing structure 6 to make the T-shaped block 610 on the outer side of the movable ring 609 rotate around the fixed shaft 608 until the T-shaped block 610 completely withdraws from the inside of the second rectangular opening 607, and then the plug 604 can be pulled out from the fixed ring 605, thereby removing the first clamping plate 601. In this way, the pipe near the lower end in the unit pipeline 5 can be replaced. When reinstalling, insert the plug 604 into the inside of the fixed ring 605, pull the pull ring 611 in the pipe fixing structure 6 to make the T-shaped block 610 on the outer side of the movable ring 609 rotate around the fixed shaft 608 until the T-shaped block 610 is completely clamped into the inside of the second rectangular opening 607, thereby installing the first clamping plate 601.
