Description

Technical Field

[0001] The utility model belongs to the technical field of coal gas recovery and utilization of submerged arc furnaces, in particular to equipment for recovering and utilizing coal gas from submerged arc furnaces. Background Art

[0002] Submerged arc furnace, also known as electric arc furnace or resistance furnace, is mainly used for reducing smelting ores, carbonaceous reducing agents and solvents and other raw materials. Coal gas is a gas containing combustible components obtained by processing coal as raw material. According to the processing method, gas properties and use, it can be divided into: water gas, semi-water gas and air gas (or producer gas) obtained by coal gasification.

[0003] When existing ore-fired furnace gas recovery and utilization equipment recycles and utilizes the gas, it is necessary to first purify the dust and impurities in the gas. Usually, the gas is purified by using a bag. This method easily causes a large amount of dust and impurities to adhere to the bag, which is prone to blockage, resulting in the gas not being able to pass through the bag better. The gas will be produced at a high temperature, which causes the bag to also be at a high temperature. It is not easy for the staff to replace the bag, which affects the gas purification effect.

[0028] Three groups of purification components 13 are arranged below the fixed plate 121. The three groups of purification components 13 are arranged in a horizontal array. The purification component 13 includes a filter plate 131. A fixed shaft 132 is fixedly connected inside the filter plate 131. The front and back sides of the fixed shaft 132 are rotatably connected to the partition 12. Two limit rods 134 are fixedly connected to the top of the filter plate 131. A straight slot is opened inside the limit rod 134. The inner wall of the straight slot contacts the outer surface of the push rod 241. By setting a movable seat 124, specifically, the motor 125 drives the half gear 251 to rotate continuously, which will cause the movable seat 124 to reciprocate, and the filter plate 131 will continuously flip, thereby achieving the cleaning effect, so that the dust and impurities attached to the filter plate 131 fall off, so that the gas can be continuously purified, avoiding the use of cloth bags and replacing the cloth bags, reducing the labor of the staff, and avoiding the risk of burns.

[0029] The top of the fixed plate 121 is fixedly connected to a baffle shell 122, and the front and back sides of the baffle shell 122 are fixedly connected to the surfaces of the two partitions 12. The right side of the inner wall of the baffle shell 122 is fixedly connected to the limiting block 221. A circulation groove 123 is provided on the right side of the fixed plate 121, and two sliding holes are provided on the left side of the movable seat 124.

Rubber covers 135 are fixedly connected to the lower left and right sides of the filter plate 131, and the bottoms of the two rubber covers 135 are fixedly connected to the bottom of the inner wall of the purification box 11. The rubber cover 133 above the filter plate 131 plays a sealing role to prevent the gas from entering the baffle shell 122, and the rubber cover 135 at the bottom of the filter plate 131 seals the bottom to prevent the gas from passing through the filter plate 131 directly without purification.

[0032] Several leakage grooves 14 are provided at the bottom of the purification box 11, and sealing gaskets 141 are inserted at the bottom of the several leakage grooves 14. The bottom of the sealing gasket 141 is fixedly connected to a connecting rod 142. By setting the sealing gasket 141, specifically after the filter plate 131 is cleaned, the electric push rod 152 is started to drive the connecting rod 142 to move downward, and the connecting rod 142 drives the several sealing gaskets 141 to move downward, opening the leakage groove 14, so that the cleaned dust falls into the storage box 15 and the dust is collected. This process does not require manual operation, which reduces labor again, and can be carried out simultaneously with cleaning the filter plate 131, thereby improving cleaning efficiency.

[0033] A storage box 15 is inserted into the base 1, and a baffle 151 is fixedly connected to the left side of the storage box 15. An electric push rod 152 is fixedly connected to the bottom of the inner wall of the storage box 15, and the top output end of the electric push rod 152 is fixedly connected to the bottom of the connecting rod 142. A sealing strip 16 is provided on the left side of the base 1, and the left side of the sealing strip 16 is in contact with the right side of the baffle 151. The sealing strip 16 is provided on the left side of the base 1 and is in contact with the baffle 151, which can play a sealing role to prevent gas overflow. When the storage box 15 needs to be cleaned, the electric push rod 152 is started to store the sealing gasket 141 into the storage box 15, and then the baffle 151 is pulled to pull out the storage box 15 to clean the dust in the storage box 15.

[0034] A specific application of this embodiment is:

[0035] The coal gas enters the purification box 11 through the air inlet pipe 112, and then the coal gas is purified by passing through a plurality of filter plates 131, so that dust and impurities adhere to the filter plates 131. The purified coal gas enters the upper part of the fixed plate 121 through the flow groove 123, and is discharged through the air outlet pipe 111. The discharged coal gas is returned to the hot furnace for recycling, making full use of the waste heat of the coal gas and improving the combustion efficiency in the hot furnace. When a lot of dust adheres to the filter plates 131, the starting motor 125 drives the half gear 251 to rotate clockwise, and the half gear 251 drives the movable seat 124 to move to the left through the convex teeth on the movable seat 124. The movable seat 124 slides on the slide rail 244, and the movable seat The left side of 124 slides on the fixed rod 242 and squeezes the spring 243. At the same time, the mobile seat 124 drives the push rod 241 to move to the left. The push rod 241 pushes the limit rod 134 to move. The limit rod 134 drives the filter plate 131 to flip. The rubber cover 133 above the filter plate 131 plays a sealing role to prevent the gas from entering the baffle 122. The rubber cover 2 135 at the bottom of the filter plate 131 seals the bottom to prevent the gas from passing through the filter plate 131 without purification. When the gear on the half gear 251 disengages from the convex tooth on the mobile seat 124, the mobile seat 124 is reset to the right under the elastic action of the spring 243, and the limit block 221 presses the mobile seat 124. The filter plate 131 is continuously flipped over, thereby achieving the cleaning effect, so that the dust and impurities attached to the filter plate 131 fall off, so that the gas can be continuously purified, avoiding the use of a bag, replacing the bag, reducing the labor of the staff, and avoiding the risk of burns. When the filter plate 131 is cleaned, the motor 125 stops, and the electric push rod 152 is started at this time to drive the connecting rod 142 to move downward, so that the connecting rod 142 drives several sealing pads 141 to move downward, and the leakage is removed. The slot 14 is opened, allowing the cleaned dust to fall into the storage box 15 and collect the dust. This process does not require manual operation, which again reduces labor, and can be carried out simultaneously with cleaning the filter plate 131, thereby improving cleaning efficiency. Subsequently, the electric push rod 152 is started to drive the connecting rod 142 to move upward, so that the sealing gasket 141 is plugged into the leakage slot 14 to seal it. A sealing strip 16 is provided on the left side of the base 1 and contacts with the baffle 151, which can play a sealing role to prevent gas overflow. When the storage box 15 needs to be cleaned, the electric push rod 152 is started to store the sealing gasket 141 in the storage box 15, and then the baffle 151 is pulled to pull the storage box 15 out, so that the dust in the storage box 15 can be cleaned.
