Description

Technical Field

[0001] The utility model relates to the technical field of gas furnace equipment, in particular to a gas furnace quenching tower. Background Art

[0002] In my country's coal coking industry, the coke oven gas from the coal gas suction pipeline generally contains impurities such as coke oven coal powder. After the coke oven gas enters the quenching tower, coal powder tar frequently agglomerates and blocks the vertical pipe, causing the gas pressure in the lower section of the gasifier to rise to 3600pa and the gas temperature in the upper section to rise by 170°C, resulting in the inability to effectively control the process parameters of the gasifier and reducing the supply of gas to the vertical furnace.

[0003] In the prior art, the gas furnace quenching tower can be divided into two chambers. The upper chamber is for combustion. When the ash, tar, etc. are lifted to the lower chamber, they are purged. That is, air or oxygen is blown into the lower chamber along the tangent direction of the chamber to make the ash and tar burn more fully. However, this treatment method is relatively expensive. The agitation of air can prevent the coke oven coal powder from compacting. Another method is to install a slag crusher, connect the pipeline and add a conveyor belt to the bottom of the gas furnace quenching tower, and first break or remove the compacted coal tar at the bottom. This method is not thorough enough, and the cost of funds and manpower invested is also high, which is not conducive to promotion. Utility Model Content

[0004] The utility model aims to provide a gas furnace quenching tower which has reasonable structural design, convenient operation, low processing cost, energy saving and environmental protection, can clean coal powder tar agglomerates online, save time and labor, and reduce safety risks.

[0005] The utility model discloses a coal gas furnace quenching tower, comprising a first quenching tower, a second quenching tower fixedly connected to the side wall of the first quenching tower, a coal gas inlet pipeline fixedly connected to the surface of the first quenching tower; a coal gas outlet pipeline fixedly connected to the surface of the second quenching tower, a first flushing water bag installed on the coal gas inlet pipeline, a first flushing water nozzle fixedly installed between the first flushing water bag and the first quenching tower; a second flushing water bag installed on the coal gas outlet pipeline, a second flushing water nozzle fixedly installed between the second flushing water bag and the second quenching tower.

[0006] A first cooling water bag is installed on the outer wall of the first quenching tower, and a first cooling water nozzle is fixedly connected between the first cooling water bag and the first quenching tower; a second cooling water bag is installed on the outer wall of the second quenching tower, and a second cooling water nozzle is fixedly connected between the second cooling water bag and the second quenching tower; the first cooling water bag and the second cooling water bag are connected by a connecting pipe.

[0007] The first flushing water bag and the second flushing water bag installed on the gas inlet pipeline and the gas outlet pipeline can spray water into the first quenching tower and the second quenching tower through the first flushing water nozzle and the second flushing water nozzle, respectively, so as to continuously flush the coal ash adhering to the inner wall of the first quenching tower and the second quenching tower and the first cooling water nozzle and the second cooling water nozzle. The flushing effect is good and the operation is convenient. The flushing can be achieved by simply opening the first flushing water nozzle and the second flushing water nozzle, which saves time and effort, and can also achieve the cooling of the first quenching tower and the second quenching tower. The cooling is to further reduce the temperature of the lower section of the gas furnace entering the quenching tower, so that the temperature of the pressurized fan casing entering the next link can operate more stably; it can solve the problem of coal powder tar agglomeration blocking the vertical pipe in the quenching tower, eliminate the fault at the first cooling water nozzle and the second cooling water nozzle, and at the same time, it can also reduce the temperature in the quenching tower of the gas furnace by 6-10°C;

[0008] The first cooling water bag and the second cooling water bag can spray water into the first quenching tower and the second quenching tower through the first flushing water nozzle and the second flushing water nozzle to cool the first quenching tower and the second quenching tower.

[0009] The inner walls of the pipes of the first flushing water nozzle and the second flushing water nozzle are fixedly connected with a cross rod, and the cross rod is located at the outlet ends of the first flushing water nozzle and the second flushing water nozzle.

[0010] A cross rod is fixedly connected to the inner wall of the pipe of the first flushing water nozzle and the second flushing water nozzle, which is more conducive to the dispersion of water after passing through the cross rod, and the interior of the first quenching tower and the second quenching tower can be fully flushed, making the flushing more thorough.

[0011] The first flushing water bag and the second flushing water bag are connected through a pipeline, and the second flushing water bag is connected to the second cooling water bag through a pipeline.

[0012] By connecting the first flushing water bag and the second flushing water bag through a pipeline, water can be injected into the first flushing water bag and the second flushing water bag at the same time, which is convenient for water injection and saves installation cost; by connecting the second flushing water bag and the second cooling water bag through a pipeline, the water inlet pipeline of the quenching tower of the two can be shared, and a separate water supply pump and pipeline are no longer required. When the water pressure is unbalanced, the valves of the outlet pipelines of the second flushing water bag and the second cooling water bag can be adjusted, which simplifies the installation steps and saves installation raw materials.

[0013] The bottom of the second cooling water bag is connected with a domestic water inlet pipeline.

[0014] The domestic water inlet pipe is provided to carry the water in the first cooling water bag and the second cooling water bag into the living area through the domestic water inlet pipe for people to use.

[0015] Inspection manholes are fixedly installed on the bottom surfaces of the first quenching tower and the second quenching tower.

[0016] The maintenance manhole is provided to timely inspect and handle the faults in the first quenching tower and the second quenching tower.

[0017] A hot circulating water outlet pipe is fixedly installed on the bottom surface of the first quenching tower and the second quenching tower.

[0018] The heat circulating water outlet pipe is arranged to allow the flushing water and cooling water in the first quenching tower and the second quenching tower to flow out through the heat circulating water outlet pipe and enter the heat circulating water pool.

[0019] Beneficial effects of the utility model:

The flushing effect is good and the operation is convenient. The flushing can be achieved by simply opening the first flushing water nozzle and the second flushing water nozzle, which saves time and effort, and can also achieve the cooling of the first quenching tower and the second quenching tower. The cooling is to further reduce the temperature of the lower section of the gas furnace entering the quenching tower, so that the temperature of the pressurized fan casing entering the next link is more stable.
