Description

Technical Field

[0001] The invention relates to the technical field of chemical industry, in particular to a multi-tube condenser flushing device. Background Art

[0002] The multi-tube condenser is an important environmental protection equipment in the fume dust removal system of the liquid crystal glass production kiln. The fume of the liquid crystal glass production kiln enters the dust removal bin after passing through the flue, desulfurization, denitrification device, air confluence, and multi-tube condenser, and then is discharged from the chimney through the induced draft fan after being filtered by the filter bag. When the dust and flue gas pass through the multi-tube condenser, the temperature drops, and the NOX, SO2 and other components in the flue gas condense into blocks when they are cold, and adhere to the inner tube wall of the multi-tube condenser. As time goes by, they gradually increase, resulting in a decrease in the heat exchange rate of the multi-tube condenser, and even causing the pipeline to be blocked and the passage of the flue gas to be blocked. In order to discharge the flue gas in time, the frequency of the induced draft fan gradually increases, which in turn causes the furnace pressure of the kiln to fluctuate, thereby affecting the product quality. At the same time, due to the decrease in the heat exchange rate of the multi-tube condenser, the overheated flue gas enters the dust removal bin, which causes the filter bag in the dust removal bin to burn and reduce the service life of the filter bag. Therefore, the tube wall of the multi-tube condenser needs to be flushed regularly. During the flushing process, personnel need to hold a water pipe and enter the narrow and high-temperature space at the top of the multi-tube condenser to operate.

[0077] The other end face of the pipe mouth of the 90-degree elbow 7 is welded and installed with one end face of the water inlet pipe 13 with an outer diameter of 57 mm and an inner diameter of 50 mm and a tubular structure. The end face of the pipe mouth of the 90-degree elbow 7 is kept coincident with the end face of the water inlet pipe 13, and the center of the end face of the pipe mouth of the 90-degree elbow 7 is kept concentric with the center of the end face of the water inlet pipe 13. In this embodiment, the water inlet pipe 13 is made of SUS304 material, and the length of the water inlet pipe 13 is 200 mm.

[0078] The above components together constitute the gun head. During installation, the central axis of the water outlet 1, the water baffle 2, the first stabilizing section 3, the first reducing section 4, the second stabilizing section 5, and the second reducing section 6 must be kept coincident during the welding and installation process.

[0079] The multi-tube condenser flushing device also includes a sliding connector 8, an M10 gasket 9, an M10 nut 10, an M10X60mm half-thread screw 11, an L-shaped rod 12, a water inlet pipe 13 and a handle 14.

[0080] The sliding connector 8 is made of SUS304 stainless steel, and its end section is a hollow square with an outer side length of 30mm and an inner side length of 20mm. Its lower end is an arc-shaped surface, and the radius of the arc-shaped surface is the same as the radius of the water inlet pipe 13. The upper end is an arc-shaped surface with a radius of 15mm. There are two gaps with a width of 10mm from the center of the arc-shaped surface with a radius of 15mm to the other end of the arc-shaped surface to form a slide groove, and the two slide grooves are symmetrical to the two opposite faces of the sliding connector 8. The lower end face of the sliding connector 8 is welded with the water inlet pipe 13 and installed at the connection between the water inlet pipe 13 and the 90-degree elbow 7, and the side with the slide groove is parallel to the end face of the water inlet pipe 13. The center line of the slide groove is in the same plane and parallel to the central axis of the booster pipe.

[0081] The L-shaped rod 12 is made of a stainless steel square tube with a side length of 20 mm, a short side length of 200 mm, a long side length of 1720 mm, the short side and the long side form an angle of 90 degrees, one end of the short side is an arc surface, and a φ10 mm through hole is concentric with the arc surface and penetrates the L-shaped rod 12, and the other end of the short side is connected to the long side and the short side and the long side form an angle of 90 degrees. The long side of the L-shaped rod 12 is parallel to the central axis of the water inlet pipe 13, the handle 14 of the L-shaped rod 12 is in the water inlet direction of the water supply flow, and the short side of the L-shaped rod 12 is inserted into the inner square hole of the sliding connector 8.

[0082] The half-thread screw 11 passes through the washer 9, the slide groove of the sliding connector 8, the through hole of the short side end of the L-shaped rod 12, the slide groove on the other side of the sliding connector 8, another washer 9, and the nut 10 is installed on the half-thread screw 11. In this embodiment, the M10 washer 9, the M10 nut 10, and the M10X60mm half-thread screw 11 are standard parts.

[0083] The short side of the L-shaped rod 12 can slide along the slide groove inside the square hole of the sliding connector 8. When the short side of the L-shaped rod 12 slides to the upper limit position of the sliding connector 8, it can rotate freely within a range of 180 degrees to the left and right.

[0084] A handle 14 is connected above the long side of the L-shaped rod 12, and the handle 14 faces the incoming water direction of the water supply flow. The handle 14 is made of a stainless steel square tube with a side length of 20 mm and is made into an "L" shape. The short side of the handle 14 is 150 mm long, the long side is 170 mm long, and the long side and the short side of the handle 14 form an angle of 90 degrees. The end face of the short side of the handle 14 is welded to the long side of the L-shaped rod 12, and the long side of the handle 14 is kept parallel to the long side of the L-shaped rod 12. The short side of the handle 14 is 1200 mm away from the connection between the long and short sides of the L-shaped rod 12.

[0085] By adjusting the position of the short side end face of the L-shaped rod 12 in the sliding connector 8, the overall height of the multi-tube condenser flushing device can be adjusted to adapt to confined spaces of different opening sizes. The water inlet pipe 13 is connected with an 8-65-20 type belt water pipe to provide continuous water supply. The handle 14 is held by the hand to insert the above-mentioned gun head into the confined space, thereby achieving the purpose of preventing people from entering the confined space and reducing safety management costs.

[0086] When in use, the water outlet 1 is inserted into the condenser tube mouth of the multi-tube condenser, and the water baffle 2 is fitted to the end face of the condenser tube. The water flows into the water inlet pipe 13 through the 8-65-20 type belt water pipe, flows to the booster pipe through the 90-degree elbow 7, and flows through the second stabilizing section 5 after being accelerated by the second reducer 6. After the flow direction is adjusted at the second stabilizing section 5, it flows to the first reducer 4, and flows through the first stabilizing section 3 after being accelerated again by the first reducer 4. After the flow direction is adjusted again, it is sprayed out from the water outlet 1 at high speed. The high-speed water flow impacts the inner tube wall of the condenser tube to remove the crystal blocks, which can improve the flushing efficiency of the multi-tube condenser. The water baffle 2 can prevent the water from overflowing from the condenser tube mouth, so as to prevent the waste of water resources. The angle of the L-shaped rod 12 relative to the gun head can be changed by rotating the handle 14, so as to complete the flushing operation of pipes in different positions.

[0087] Furthermore, the installation methods of the multi-tube condenser flushing device include single-set installation, multiple-set continuous or interval installation, and single water supply pipeline and multiple gun heads in combination.
