[0001] The invention relates to the technical field of coke oven airing, and in particular to a side-loading coal type coke oven airing dust removal system. Background Art

[0002] Coking is a multi-source pollution industry, and smoke is the main pollutant emitted during the coking production process. When the carbonization chamber is about to be discharged, the water seal cover of the coal loading hole and the water seal cover of the riser need to be opened to dry the furnace. During the drying of the furnace, a small amount of raw coal gas and smoke will escape. There is currently no relevant device to deal with the emissions from the drying furnace.

[0003] In the past, there were the following disadvantages in drying the oven: 1. It was not convenient to collect and remove the smoke and dust during the drying process of the coke oven, and it was not possible to prevent the escape of smoke, which seriously polluted the environment. Therefore, we proposed a side-loading coal type coke oven drying dust removal system. Summary of the invention

[0004] The main purpose of the present invention is to provide a side-loading coal-type coke oven airing and dust removal system, which can effectively solve the problems in the background technology.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0007] Furthermore, a ladder is provided at the corner of the frame of the smoke guide vehicle.

[0008] Furthermore, a plunger valve core is arranged inside the end of the plunger valve housing.

[0009] Furthermore, the air inlet port of the air storage tank is connected to the air outlet end of the air pump through a pipeline, and the air inlet end of the bag filter is connected to the air outlet port of the air storage tank through a pipeline.

[0010] Furthermore, the power output end of the first winch is connected to the top of the smoking hood with sleeve through a steel wire rope.

[0011] Furthermore, a grabber is installed in the smoke hood, and the power output end of the second winch is connected to the grabber through a steel wire rope.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The smoke collecting hood is connected with the smoke guide vehicle frame through a slewing bearing, and the smoke collecting hood is connected with the smoke guide vehicle frame through a slewing bearing. The driving rotary device drives the guide wheel to rotate the smoking cross pipe to the water seal cover of the riser. At the same time, it is necessary to ensure that the smoking hood with sleeve is just above the water seal cover to be opened. After the smoking hood with sleeve moves to the corresponding position, the first winch drives the smoking hood with sleeve to descend through the guide wheel using a wire rope. The outer sleeve plays a guiding role. After it descends to the appropriate position, the water seal cover is opened. After the smoking hood with sleeve descends, it is connected with the smoking cross pipe. At this time, there is negative pressure in the pipeline, which absorbs the smoke and dust emitted from the riser into the pipeline and sends it to the smoke conveying pipeline. After the drying of the furnace is completed, the water seal cover is closed, and the first winch drives the smoking hood with sleeve to rise through the guide wheel using a wire rope. When it rises to the top, the upper opening of the smoking hood with sleeve is disconnected from the smoking cross pipe, and the cycloid pinwheel drives the rotary device to drive the roller to rotate the smoking cross pipe to the upper part of the smoke guide vehicle and retract it to its original position.The smoke extraction hood is installed on the frame of the smoke guide vehicle. During installation, it is necessary to ensure that the vertical center line of the smoke extraction hood is parallel to the center line of the water seal cover of the coal loading hole on the top of the coke oven, so that as the smoke guide vehicle moves, the smoke extraction hood can completely cover the coal loading hole. A gripper is installed in the smoke extraction hood, and is connected to the second winch. In this way, by controlling the lifting and lowering of the second winch, the lifting and lowering of the gripper can be controlled, thereby controlling the switch of the water seal cover of the coal loading hole. The plunger valve includes a plunger valve shell and a plunger valve core, which are installed on the side of the smoke extraction hood. The smoke outlet pipe is installed on the plunger valve shell and is connected to the smoke conveying pipe. When the plunger valve core is pulled out, the smoke outlet pipe is connected to the smoke extraction hood, which can absorb the scattered smoke. After the plunger valve core is pushed in, the smoke conveying pipe and the coke oven airing furnace are connected. The smoke extraction hoods are separated to facilitate their respective operation. The high-temperature resistant fireproof cloth is installed at the lower part of the smoke extraction hood. When the water seal cover of the coal loading hole is opened by the gripper, there may be an open flame. At this time, the high-temperature resistant fireproof cloth will isolate the open flame from the surrounding environment. When the water seal cover needs to be opened to dry the furnace on site, the staff will drive the smoke guide vehicle to the corresponding position to make the smoke extraction hood at the water seal cover of the coal loading hole to be opened. At this time, the staff will pull out the plunger valve core to connect the smoke outlet pipe and the smoke extraction hood, and then control the second winch to descend to stop the gripper at the appropriate position. With the assistance of the staff, the gripper grabs the upper part of the water seal cover. At this time, open the wire rope of the second winch, and the gripper will drive the water seal cover to move upward, thereby opening it. The water seal cover is used to dry the furnace. At this time, the smoke escaping from the coal loading hole will be collected by the smoke hood and transported to the smoke conveying duct. The high-temperature resistant fireproof cloth will cover the space between the smoke hood and the water seal seat to prevent smoke from overflowing. The smoke guide car frame runs on the track on the top of the coke oven through its own single-sided wheel. The bag dust collector is installed on the smoke guide car frame. A condenser and a gas storage tank are installed at one end of the bag dust collector, an induced draft fan is installed on one side of the bag dust collector, and an air pump is installed at one end of the induced draft fan. These devices are all installed on the smoke guide car frame, and the smoke conveying duct is connected to the column and the smoke outlet pipe, and the other end is connected to the fire damper. After the smoke enters the smoke conveying duct, if there is an open flame, the open flame will be extinguished after passing through the fire damper, and then the smoke Entering into the condenser, the high-temperature gas sucked in is cooled to below 120° through the condenser, and then enters into the bag-type dust collector. After being filtered by the bag-type dust collector, the induced draft fan extracts the gas from the air outlet of the bag-type dust collector into the atmosphere. The air pump and the air storage tank are connected by a pipeline, and the air pump replenishes air for the air storage tank. The air storage tank is connected to the blowing air bag of the bag-type dust collector. When the pressure difference of the bag-type dust collector is too high, it needs to be sprayed. At this time, the air storage tank supplies air to the blowing air bag of the bag-type dust collector, and back-blows the bag-type dust collector to make the bag-type dust collector work normally. Through the above process, it is convenient to collect and remove the smoke in the drying process of the coke oven, which can prevent the escape of smoke and reduce the pollution to the environment.
