Abstract
The utility model discloses a coke oven sectional type discharge pressure balancing unit, including communicating pipe, two sections discharge are connected respectively to the both ends of communicating pipe, and the junction of communicating pipe and discharge all is provided with the valve. Compared with the prior art, the device adds a communicating pipe at the sectional type gas collecting pipe subsection of the coke oven, and two ends of the communicating pipe are respectively connected with two sections of gas collecting pipes through valves, so that gas between the disconnected gas collecting pipes can be communicated, and therefore gas in the gas collecting pipe with high pressure flows into the gas collecting pipe with low pressure, and finally pressure balance of the two sections of gas collecting pipes is achieved.
Description
Technical Field
The utility model relates to a coke oven auxiliary device, in particular to a sectional type gas collecting pipe pressure balancing device of a coke oven.
Background
The design of two sections of gas collecting pipes is adopted in large coke ovens in the coking industry, and the pressure of the gas collecting pipes between the two sections is controlled separately, so that the pressure deviation between the two sections of gas collecting pipes is large, the balance is difficult to keep, and the adverse effects on coke oven production and environmental protection management and control are brought.
At present, the problem of pressure balance of two sections of gas collecting pipes of a coke oven is mainly solved from software control in the industry, but the problem can not be completely solved all the time.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: in order to overcome the defects of the prior art, the utility model provides a coke oven sectional type gas collecting pipe pressure balancing device, which can balance the pressure of gas collecting pipes at two ends.
The technical scheme is as follows: a coke oven sectional type discharge pressure equaliser, including communicating pipe, two sections discharge are connected respectively to the both ends of communicating pipe, and the junction of communicating pipe and discharge all is provided with the valve.
The ammonia water spraying device comprises an ammonia water spraying nozzle, wherein the ammonia water spraying nozzle introduces ammonia water into the communicating pipe from the outside and is used for spraying the inner wall of the communicating pipe. Therefore, the sundries on the inner wall of the communicating pipe can be cleaned, and the sundries such as tar and the like on the inner wall of the communicating pipe are prevented from being accumulated.
Specifically, the communicating pipe is in an inverted U shape and includes vertical portions located at both sides and a horizontal portion located in the middle.
The ammonia nozzle is disposed within the lateral portion. Thus the removed impurities can naturally drop and are discharged out of the communicating pipe from the vertical part.
The valve is arranged on the vertical part through a flange, and the distance between the valve and the bottom end of the vertical part is greater than 1/3 of the pipe diameter of the gas collecting pipe.
Has the advantages that: compared with the prior art, the device adds a communicating pipe at the sectional type gas collecting pipe subsection of the coke oven, and two ends of the communicating pipe are respectively connected with two sections of gas collecting pipes through valves, so that gas between the disconnected gas collecting pipes can be communicated, and therefore gas in the gas collecting pipe with high pressure flows into the gas collecting pipe with low pressure, and finally pressure balance of the two sections of gas collecting pipes is achieved.

Detailed Description
The utility model is further explained in detail by taking a JN 60-6 type 6m top-mounted coke oven as an example, and the coke oven adopts a sectional type gas collecting pipe to collect the raw coke oven gas generated by coking.
As shown in figure 1, the sectional gas collecting pipe pressure balancing device of the coke oven mainly comprises a communicating pipe 1, a valve 3 and an ammonia water nozzle 4.
Specifically, the communicating pipe 1 is made into a U shape by adopting a pipe diameter pipeline with the diameter of more than DN300, and is communicated between the two sections of gas collecting pipes 2 in an inverted manner. The communication pipe 1 specifically includes vertical portions 11 at both sides and a horizontal portion 12 at the middle. The valve 3 is arranged on the vertical part 11, and the distance between the valve 3 and the bottom end of the vertical part 11, namely the distance between the valve 3 and the joint of the gas collecting pipe is more than 1/3 of the pipe diameter of the gas collecting pipe.
Meanwhile, the ammonia water nozzle 4 is arranged on the top of the inner wall of the transverse part 12 and used for introducing ammonia water into the communicating pipe 1 from the outside to spray the inner wall of the communicating pipe 1 so as to remove impurities such as tar. The number of the ammonia water nozzles is determined according to the length of the communicating pipe 1, and the longer the communicating pipe 1 is, the more the ammonia water nozzles 4 are provided. Of course, the ammonia water nozzle 4 may be provided also on the vertical portion 11 as needed.
After the installation and connection are completed, an air tightness experiment is carried out, and after the experiment is qualified, the valve 3 is opened, so that the gas between the two sections of gas collecting pipes 2 is communicated, the gas in the gas collecting pipe 2 with high pressure can flow into the gas collecting pipe 2 with low pressure, and finally the pressure balance of the two sections of gas collecting pipes 2 is achieved.
