Technical Field
The invention relates to a dust-containing gas discharge device of a dry quenching coke powder bin, belonging to the technical field of dry quenching.
Background
The dry quenching is to cool the red coke by utilizing the heat exchange between cold inert gas and the red coke in a dry quenching furnace, the inert gas absorbing the heat of the red coke transfers the heat to a dry quenching boiler to generate steam (which can be used for power generation, heating and the like), and the cooled inert gas is dedusted and then blown into the dry quenching furnace by a circulating fan to cool the red coke.
In the production process of dry quenching coke, a large amount of coke powder can be generated, the coke powder collected from each point finally enters a dry quenching coke powder bin through a pneumatic conveying system, the coke powder is stirred by a humidifier and then discharged from the bottom, redundant gas in the bin is usually pumped out from the top of the coke powder bin by an induced draft fan, and the redundant gas is filtered by a cloth bag in the middle and then discharged into the atmosphere.
In actual production, the gas discharged to the atmosphere from the coke powder bin contains a large amount of coke powder due to the easy-to-damage failure of the cloth bag and the like, so that the coke powder is wasted, the environment is polluted, the environmental protection risk is brought, the overhaul and maintenance of the equipment are reduced, the working strength is reduced, and normal production is maintained.
Disclosure of Invention
The invention aims to provide a dust-containing gas discharge device of a dry quenching coke powder bin, which solves the technical problem.
In order to achieve the purpose, the invention adopts the technical scheme that:
the utility model provides a dry coke quenching burnt powder storehouse dusty gas discharging equipment, including dry coke quenching burnt powder storehouse, pulse sack blowback dust remover, the draught fan, the valve, heat accumulation cooler and ground dust removal station, burnt powder storehouse entry strength ash conveying pipeline passes through the pipe fitting valve to be connected in dry coke quenching burnt powder storehouse entry, pulse sack blowback dust remover entry passes through the valve pipe fitting and links to each other with dry coke quenching burnt powder storehouse export, pulse sack blowback dust remover export passes through the pipe fitting valve with the draught fan entry and is connected, the draught fan export passes through the connecting tube and links to each other with heat accumulation cooler entry, the last safety control valve that sets up of connecting tube, the heat accumulation cooler export passes through the pipe fitting valve with ground dust removal station entry and is connected.
The technical scheme of the invention is further improved as follows: the blowing frequency of the pulse bag back-blowing dust collector is adjusted according to the actual production condition.
The technical scheme of the invention is further improved as follows: the pulse cloth bag back-blowing dust collector is arranged at the top of the coke dry quenching coke powder bin, and the pulse cloth bag back-blowing dust collector and the coke dry quenching coke powder bin are of a structure distributed up and down.
The technical scheme of the invention is further improved as follows: the power setting of the draught fan needs to ensure that the internal pressure of the coke dry quenching coke powder bin is micro negative pressure, so that the explosion-proof plate of the coke powder bin is prevented from jumping.
The technical scheme of the invention is further improved as follows: the draught fan is connected with a connecting pipeline of the heat storage cooler on an inlet pipeline of the heat storage cooler, and the inlet pipeline of the heat storage cooler has a gas conveying function.
The technical scheme of the invention is further improved as follows: the inlet pneumatic ash conveying pipeline of the coke powder bin is positioned at the top of the dry quenching coke powder bin.
The technical scheme of the invention is further improved as follows: the bottom of the dry quenching coke powder bin is provided with a coke powder unloading and conveying system.
The technical scheme of the invention is further improved as follows: and a gas discharge port is arranged on a pipeline between the outlet of the induced draft fan and the valve.
The working process is as follows: the coke powder collected at each point (focus, focus discharge and the like) of the dry quenching system is conveyed into a dry quenching coke powder bin through a coke powder bin inlet pneumatic dust conveying pipeline, dust-containing gas in the bin is subjected to first-step dust removal through a pulse cloth bag back-blowing dust remover, the coke powder is stirred by a humidifier and then transported outwards, the gas is extracted by an induced draft fan after the first-step dust removal, and the gas is cooled by a heat storage cooler along a pipeline and then enters a ground dust removal station for further dust removal.
Due to the adoption of the technical scheme, the invention has the following technical effects:
the invention connects the outlet of the pulse bag reverse-blowing dust collector connected with the outlet of the dry quenching coke powder bin with the heat storage cooler and the ground dust removal station through the induced draft fan and the connecting pipeline, so that the gas treated by the pulse bag reverse-blowing dust collector enters the ground dust removal station for secondary treatment and is not directly discharged into the atmosphere, and if the pulse bag reverse-blowing dust collector fails, the gas at the outlet of the induced draft fan is dust-containing gas and does not have the risk of discharging coke powder after entering the ground dust removal station for secondary treatment.
When the dry quenching coke powder bin is maintained and the feeding is stopped, the valve of the connecting pipeline between the induced draft fan and the heat storage cooler can be closed, so that the risk of dust leakage is avoided.
The invention has simple structure, easy modification and low cost, can effectively avoid the discharge of dust-containing gas under the conditions of cloth bag damage or other abnormal conditions of the pulse cloth bag reverse blowing dust remover, reduces the environmental protection risk, reduces the overhaul and maintenance of equipment, reduces the working strength and maintains normal production.
