Description

Technical Field

[0001] This utility model relates to the technical field of coke oven heating systems, specifically to a dual heating system for maintaining oven temperature. Background Technology

[0002] When severe leakage occurs in the regenerator for heating with blast furnace gas, the blast furnace gas leaks into the regenerator, causing it to burn entirely within the regenerator. This lowers the combustion chamber temperature and raises the regenerator temperature. Over time, this can deform or even block the regenerator's insulating bricks. If the regenerator is blocked, blast furnace gas and air cannot enter the combustion chamber, leading to a temperature drop. This device can be used to maintain the combustion chamber temperature. Therefore, this invention provides a dual heating system with furnace temperature maintenance features to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a dual heating system for furnace temperature preservation, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dual heating system for furnace temperature preservation, comprising a main gas pipe, a first branch pipe, a second branch pipe, a first gas exchange valve, a supply pipe, and a condenser pipe. The lower rear side of the main gas pipe is welded with a first branch pipe in a connected structure, and the lower right side of the main gas pipe is welded with a second branch pipe in a connected structure. The first branch pipe and the second branch pipe are staggered vertically. A control valve A is provided on the first branch pipe, and the first gas exchange valve is installed at the right end of the first branch pipe.

[0005] A control valve B is installed on the second branch pipe, and a second gas exchange valve is installed at the right end of the second branch pipe. Both the first gas exchange valve and the second gas exchange valve are equipped with supply pipes.

[0006] A drain pipe connects the condenser pipe located at the front of the lower end of the main gas pipe to the condenser pipe located at the front.

[0007] In a preferred embodiment of this utility model, a diversion pipe A is installed at the lower end of the first branch pipe, a diversion pipe B is installed at the lower end of the second branch pipe, and a control valve is installed on both the diversion pipe A and the diversion pipe B.

[0008] As a preferred embodiment of this utility model, the supply pipe is provided with two branches, and the two supply pipes are in a vertical structure.

[0009] In a preferred embodiment of this invention, the upper end of the supply pipe is connected to the coke oven.

[0011] As a preferred embodiment of this utility model, the first branch pipe and the second branch pipe have the same length, both being 2.5m.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by splitting the lower end of the main gas pipe into two branch pipes and installing a gas exchange valve on the branch pipes, a dual heating effect is formed, which increases the heating temperature and prevents the carbonization chamber from collapsing due to excessively low temperature. The increased temperature also reduces phenomena such as coke collapse and black smoke.

[0014] 2. In this utility model, a drain pipe with a connected structure is provided at the lower end of the main gas pipe, and the drain pipe flows into the condenser pipe. Moreover, a diversion pipe is installed at the bottom of both branch pipes, which solves the problem of moisture in the gas. Attached Figure Description

[0021] Example: Figure 1-2 This utility model provides a technical solution: including a main gas pipe 1, a first branch pipe 2, a second branch pipe 3, a first gas exchange valve 6, a supply pipe 7, and a condenser pipe 11. The first branch pipe 2, which is in a connected structure, is welded to the rear side of the lower end of the main gas pipe 1. The second branch pipe 3, which is in a connected structure, is welded to the right side of the lower end of the main gas pipe 1. The first branch pipe 2 and the second branch pipe 3 are in an alternating structure. A control valve A4 is provided on the first branch pipe 2. The first gas exchange valve 6 is installed on the right end of the first branch pipe 2.

[0022] A control valve B8 is installed on the second branch pipe 3, and a second gas exchange valve 10 is installed on the right end of the second branch pipe 3. A supply pipe 7 is installed on both the first gas exchange valve 6 and the second gas exchange valve 10.

[0028] The first branch pipe 2 and the second branch pipe 3 have the same length, both 2.5m.

[0029] Working principle:

[0030] ① Due to leakage between the two combustion chambers and the regenerator, the blast furnace gas cannot be supplied to the combustion chamber for heating normally. Since the coke oven gas does not pass through the regenerator, it can be used for heating.

[0031] ② Make an opening above the blind flange of the coke oven gas, install a control valve, and weld a 50mm pipe to extend the main gas pipe to the two combustion chambers in the coke oven basement. Make an opening down the main gas pipe to branch out two branch pipes to supply gas to the two combustion chambers.

[0032] ③ Because the gas contains moisture, drainage pipes need to be installed on the main gas pipe and branch pipes to prevent water retention from affecting heating.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
