example 1

[0065] use Figure 8 to Figure 14 The dry-type packed tower with a layer of misplaced composite packing support is used to remove naphthalene from coke oven gas, and it can also be called dry-type naphthalene-removed tower. Composition of coke oven gas: nitrogen N 2 : 3%, Oxygen O 2 : 0.5%, hydrogen H 2 : 60%, carbon monoxide CO: 7.5%, carbon dioxide CO 2 : 2.3%, methane CH 4 : 24.3%, heavy hydrocarbons C n h m : 2.4%. The content of main impurities: tar mist: 50mg / Nm 3 , Naphthalene: 400mg / Nm 3 , Benzene: 4000mg / Nm 3 , hydrogen sulfide: 200mg / Nm 3 . The content of main impurities after purification is required: tar mist: less than 5mg / Nm 3 , naphthalene: less than 20mg / Nm 3 , hydrogen sulfide: less than 5mg / Nm 3 . Single tower processing coke oven gas volume 15000Nm 3 / h.

[0066] Control the operating pressure of the above-mentioned dry denaphthalene removal tower to 20kPa, the maximum operating temperature to 260°C, and the diameter of the tower to 4.8 mete...

example 2

[0069] use Figure 1 to Figure 7 A dry-type packed tower with a layer of fitted composite packing support removes benzene from coke oven gas, and it can also be called a dry-type debenzene tower. Composition of coke oven gas: nitrogen N 2 : 3%, Oxygen O 2 : 0.3%, hydrogen H 2 : 61.2%, carbon monoxide CO: 6.5%, carbon dioxide CO 2 : 2.0%, methane CH 4 : 24.6%, heavy hydrocarbons C n h m : 2.4%. The content of main impurities: tar mist: 50mg / Nm 3 , Naphthalene: 50mg / Nm 3 , Benzene: 3000mg / Nm 3 , hydrogen sulfide: 20mg / Nm 3 . The content of main impurities after purification is required: Benzene: less than 1mg / Nm 3 . Single tower processing coke oven gas volume 10000Nm 3 / h.

[0070] Control the operating pressure of the above-mentioned dry-type debenzene tower to 50kPa, the maximum operating temperature to 160°C, and the diameter of the tower to be 3.6 meters. Lay 2 layers of stainless steel wire mesh on the support of the fitted composite packing, and then instal...

Abstract

The invention discloses a dry-type packed tower capable of quickly unloading fillers. The dry-type packed tower includes an upper head, a cylinder and a lower discharge funnel. The dry-type packed tower also includes a One or more layers of composite packing support, the composite packing support realizes the opening, closing and size adjustment of the discharge channel through the sliding of at least one moving grid plate on the track. The dry packing tower capable of quickly removing fillers of the present invention can be convenient and fast in loading and unloading solid particle fillers such as desulfurizers, adsorbents, catalysts, etc., and saves labor and effort. When unloading, when the preparations are ready, just open the traction hole and the funnel mouth of the lower discharge funnel, and at least one movable grid can be pulled by external force, so that the movable grid can be connected with other movable grids (or fixed grids) ) to change the relative position to form a discharge channel, so that the filler placed on the composite filler support falls through the discharge channel, and the filler enters the lower discharge funnel and falls into the transport vehicle for transportation.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a dry packed tower capable of quickly removing packing. Background technique [0002] Dry packed towers include dry desulfurization of impurities such as sulfides in sulfur-containing gases such as natural gas, coke oven gas, semi-coke tail gas, water gas, semi-water gas, coal bed methane, oilfield gas, biogas, shift gas, and blast furnace gas. Towers or desulfurization reactors, including dry denaphthalene towers and debenzene towers for dry removal of coke oven gas, semi-coke tail gas and other impurities containing naphthalene, benzene, ammonia, etc., and dry removal of sulfur dioxide in flue gas Desulfurization towers and other packed towers using solid particles. [0003] The usual dry packed tower is equipped with packing materials such as desulfurizer, adsorbent, catalyst, etc. These packing materials need to be replaced regularly. If the packing is manually re...
