Description

Technical Field

[0001] The utility model relates to the technical field of waste heat recovery equipment, in particular to a waste heat recycling energy-saving device. Background Art

[0002] With the development of society, conventional heating equipment such as boilers will recover waste heat to achieve energy-saving effects. Among them, the recovery of waste heat from high-temperature flue gas is of great significance. Its characteristics are large total output, concentrated production points, strong continuity, and beneficial to recovery and utilization. The calorific value sent accounts for 40% to 50% of the total calorific value. The waste heat recovery calorific value can be used for production and processing or daily life heat and power generation capacity.

[0003] In the prior art, the heat in the exhaust flue gas is generally transferred to the medium such as water flowing through the heat exchanger, thereby increasing the temperature of the medium. The temperature of the flue gas itself decreases, while the temperature of the medium increases, thereby achieving the effect of waste heat recovery.

[0004] However, in actual use, before the flue gas enters the waste heat recovery device, it is necessary to pre-treat the flue gas to remove impurities such as particulate matter and sulfides to protect the normal operation of the waste heat recovery equipment. The conventional pre-treatment method generally uses bolts to install the filter, and the flue gas passes through the filter so that the sulfides in the flue gas can be blocked. However, after long-term use, the filter needs to be replaced, that is, by using a screwdriver to unscrew the bolts and then take out the filter. When this method is used in a higher or narrow space, workers need to use ladders and other tools to cooperate, which makes the workers' movements more inconvenient, which will affect the replacement time and even affect the normal use time of the boiler.

DETAILED DESCRIPTION

[0023] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] See also Figure 1-Figure 7 The utility model provides a technical solution: a waste heat recycling energy-saving device, including a body 1, a switch door 2 is hinged on the left side of the front end of the body 1, and a filter screen 4 is slidably connected to the upper and lower sides of the body 1. Two push blocks 3 are fixedly connected to the right end of the switch door 2. The push blocks 3 on the upper and lower sides are symmetrically designed, and the separated sides of the two push blocks 3 are installed with protrusions. Two mounting grooves 7 are opened on the right side of the body 1, and a push rod 9 is slidably connected inside the mounting groove 7. The left and right ends of the filter screen 4 are fixedly connected with mounting blocks 5, and the adjacent sides of the mounting blocks 5 on the upper and lower sides are opened with card slots 6, and the mounting grooves 7 match the card slots 6.

[0026] The mounting block 5 limits the filter 4 so that the filter 4 will not shift inside the machine body 1. When the push block 3 slides into the machine body 1, the push block 3 can push the push rod 9 to engage with the inside of the card slot 6, thereby fixing the position of the mounting block 5. At this time, the switch door 2 is in a closed state with the machine body 1, so that the filter 4 can be fixed for a second time, thereby allowing the filter 4 to be stably installed inside the machine body 1.

[0027] Embodiment 2

[0028] On the basis of Example 1, in order to realize automatic engagement and disengagement of the filter 4 so that it can be conveniently replaced, the separated sides of the upper and lower push rods 9 are fixedly connected with a placement block 8, and the other side of the placement block 8 is designed as an arc. The outer sleeve of the push rod 9 is provided with a spring 10, one end of the spring 10 is fixedly connected to the inner wall of the mounting groove 7, and the other end of the spring 10 is fixedly connected to the side of the placement block 8 close to the push rod 9, the outer part of the placement block 8 is slidably connected to the inside of the mounting groove 7, and the outer part of the push rod 9 is engaged with the inner part of the slot 6.

[0029] When the switch door 2 is closed, the protrusion on the inner side of the push block 3 will first contact the arc end of the placement block 8, and then push the placement block 8 to move inward, at this time, the placement block 8 can push the push rod 9 to engage with the slot 6, and at the same time, the placement block 8 can squeeze the spring 10 to deform. When the switch door 2 is opened, the push block 3 will detach from the inside of the body 1. At this time, the spring 10 can make a reset movement, and then the spring 10 can push the placement block 8 to move upward, so that the placement block 8 can drive the push rod 9 to move upward, so that the push rod 9 can detach from the inside of the slot 6, so that the push rod 9 no longer restricts the filter 4, and it can be conveniently disassembled and replaced.

[0030] Embodiment 3

[0031] On the basis of Example 2, in order to achieve enhanced recovery effect and improve safety performance, the top of the body 1 is fixedly connected to the exhaust pipe 11, the inside of the exhaust pipe 11 is slidably connected to the slider 12, the outside of the slider 12 is fixedly connected to four limit blocks 13, the top of the slider 12 is fixedly connected to the limit column 14, the outside of the limit column 14 is sleeved with a spring 16, the top of the limit column 14 is fixedly connected to the limit groove 17, the slider 12 is cross-shaped, the outside of the limit block 13 is slidably connected to the inside of the limit groove 17, one end of the spring 16 is fixedly connected to the upper side of the slider 12, and the other end of the spring 16 is fixedly connected to the lower side of the blocking block 15.

[0032] After the flue gas passes through the filter 4 and the manifold with the medium inside, the flue gas will continue to flow upward and gather on the upper side of the body 1, so that the heat can be maintained inside the body 1, and the heat can continue to heat the medium through the air, so that the waste heat recovery effect is better, thereby improving the energy saving effect, and when the internal pressure of the body 1 is high, the flue gas will push the blocking block 15 open, so that the blocking block 15 can drive the limiting column 14 to slide upward, and the limiting column 14 can drive the slider 12 and the limiting block 13 to slide upward, so that the slider 12 can squeeze the spring 2 16 to produce deformation, and when the internal pressure of the body 1 is balanced, the spring 2 16 will perform a reset movement, so that the spring 2 16 can pull the blocking block 15 to slide downward, so that one end of the blocking block 15 fits with the top of the exhaust pipe 11, thereby continuing to recover the waste heat for the second time.

[0033] In actual use, by pulling the switch door 2 outward, the push block 3 can fall off from the inside of the machine body 1, and it no longer presses the placement block 8, so that the placement block 8 no longer presses the spring 10. At this time, the spring 10 can make a reset movement, so that the spring 10 can push the placement block 8 to move outward, so that the placement block 8 can drive the push rod 9 to fall off from the inside of the card slot 6, so that the installation block 5 is no longer restricted, so that the filter 4 can be directly drawn out from the inside of the machine body 1. When the filter 4 needs to be installed, the filter 4 can be installed by sliding the filter 4. Into the interior of the body 1, so that the installation block 5 can slide inside the body 1, at this time, by closing the switch door 2, the switch door 2 can drive the push block 3 to slide into the interior of the body 1, and then the push block 3 can push the placement block 8 to move inward, so that the placement block 8 can squeeze the spring 10 to produce elastic deformation, and the placement block 8 can push the push rod 9 to engage with the inside of the card slot 6, so that the filter 4 can be conveniently installed. This process is simple and convenient, so that the replacement efficiency is high, and it will not affect the normal use of the boiler.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
