Embodiment 1

[0049] This embodiment provides a coke oven regenerator, including:

[0050] The coke oven regenerator body 101, including the first furnace wall 102;

[0051] The gas inlet 103 is arranged on the first furnace wall 102, and is used to receive the ammonia-containing gas so that the ammonia-containing gas flows into the denitration area 104 inside the coke oven regenerator body 101;

[0052] The gas distribution device includes a stopper 105, the stopper 105 is arranged inside the coke oven regenerator body 101, and is located below the gas inlet 103, and the top surface of the stopper 105 is used to contact the Ammonia-containing gas to change the flow direction of the ammonia-containing gas.

[0053] Thus, when the coke oven regenerator is in use, ammonia-containing gas enters the coke oven regenerator body 101 through the gas inlet 103, the temperature inside the coke oven regenerator is high, and the temperature of the ammonia-containing gas is low , so after the ammonia-...

Embodiment 2

[0059] combined with figure 1 , attached figure 2, on the basis of Embodiment 1, there are multiple gas inlets 103, a plurality of gas inlets 103 are arranged at intervals along the length direction of the furnace wall, and the top surface of the stopper 105 is along the first furnace wall 102 extends lengthwise.

[0060] Therefore, preferably, one or more grooves 106 are provided on the top surface of the block 105, and the grooves 106 extend along the horizontal direction of the furnace wall. Setting the groove 106 can make the ammonia-containing gas continue to flow along the groove 106 after contacting the top surface of the stopper 105, instead of directly flowing downward, thereby further increasing the ammonia-containing gas and the The mixing time of the gas inside the regenerator in the denitration area 104.

[0061] As a preferred implementation of this embodiment, the coke oven regenerator further includes regenerator bricks, and the regenerator bricks include a...

Embodiment 3

[0064] combined with image 3 , attached Figure 4 , as a preferred implementation of this embodiment, on the basis of Embodiment 1, the gas distribution device further includes a support, and the support is connected or overlapped with the block 105 and the coke oven regenerator body 101 , so that there is a set distance between the top surface of the stopper 105 and the bottom of the coke oven regenerator body 101 .

[0065] As a preferred implementation of this embodiment, the support includes a first support 110, the first support 110 is arranged on the first furnace wall 102, and is connected to one end of the block 105; As a preferred implementation of this embodiment, the coke oven regenerator further includes a second furnace wall 111, the second furnace wall 111 is opposite to the first furnace wall 102, and the support member further includes a second A support 112 , the second support 112 is arranged on the second furnace wall 111 and connected to the other end of...

Abstract

The invention relates to a coke oven regenerative chamber. The coke oven regenerative chamber comprises a coke oven regenerative oven body, gas inlets and a gas distribution device; the coke oven regenerative chamber body comprises first oven walls, and the gas inlets are formed in the first oven walls and used for receiving ammonia-containing gas to make the ammonia-containing gas flow into a denitration region inside the coke oven regenerative chamber body; the gas distribution device comprises a baffle block, the baffle block is arranged in the coke oven regenerative chamber body and located below the gas inlet, and the top face of the baffle block is used for making contact with the ammonia-containing gas to change the flow direction of the ammonia-containing gas. When the gas distribution device is arranged, the top face of the baffle block makes contact with the ammonia-containing gas to change the flow direction of the ammonia-containing gas, the mixing time of gas inside the coke oven regenerative chamber and the ammonia-containing gas which are mixed in the denitration region is prolonged, the mixing evenness is improved, and the denitration efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of coke oven regenerator structure, in particular to a coke oven regenerator. Background technique [0002] The coke oven regenerator is generally a space built with refractory bricks to preheat air or lean gas with high-temperature waste gas, and is located at the lower part of the coke oven body. [0003] The existing coke oven regenerator includes a coke oven regenerator body, and a gas inlet is provided on the coke oven regenerator body, and the gas inlet is used to receive ammonia-containing gas so that the ammonia-containing gas flows into the coke oven for heat storage The denitrification is carried out in the chamber body. [0004] The existing coke oven regenerator has low denitrification efficiency for ammonia-containing gas, and the use effect is not good. Contents of the invention [0005] The invention provides a coke oven regenerator to improve the denitrification effect of the coke oven re...
