Description

Technical Field

[0001] The utility model relates to the technical field of soot blower equipment, in particular to a laminated tower jet soot blower. Background Art

[0002] A device used to remove soot from boiler heating surfaces. It typically consists of a sootblower and operating valves. It is typically installed on the furnace wall, including the furnace, horizontal flue, and tail flue. Sootblower types include gun, rotary, and telescopic. Regular use of sootblowers to promptly remove soot from various heating surfaces is crucial for ensuring safe and economical boiler operation.

[0003] During the use of the current soot blower, due to the influence of the high temperature environment inside the furnace, the soot blowing gun tube is prone to jamming, failure, steam leakage and other phenomena. The equipment failure rate is relatively high and requires a high level of maintenance. If the failure is not handled for a long time, it will cause damage to the tube wall. At the same time, during the soot blowing process inside the furnace, the traditional soot blower has low working efficiency during the cleaning process, which leads to dust accumulation, coking, slagging and other problems in the horizontal flue area, affecting the normal use of the boiler furnace. Utility Model Content

[0004] The purpose of the utility model is to provide a laminated tower jet sootblower, which improves the working efficiency of the sootblower by optimizing and improving the traditional sootblower structure, so as to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

A core pipe is provided below the transition pipe. A plurality of evenly distributed jet heads are provided on the outer wall of the core pipe. The lower part of the core pipe is connected to the main cavity, and a sealing gasket is provided at the connection position between the core pipe and the main cavity.

[0007] As a further solution of the present invention: the transition pipe includes a transition gasket, a transition cavity, a mounting chuck and a conical sealing connection sleeve, the transition gasket is arranged at the rightmost position of the transition pipe, and the right end of the transition gasket is cooperated with the core pipe, the transition cavity is arranged at the left side of the transition gasket, and the left side of the transition cavity is provided with a mounting chuck, the mounting chuck is cooperated with the conical sealing connection sleeve, and the mounting chuck is cooperated with the main pipe through the conical sealing connection sleeve.

[0008] As a further solution of the present invention: the conical sealing connection sleeve includes an external interface, an elastic limit block and an internal thread layer. The conical sealing connection sleeve is a conical hollow structure, and the conical sealing connection sleeve is arranged on the mounting chuck, and an external interface is arranged at the upper end thereof. A plurality of evenly distributed elastic limit blocks are arranged on the outer wall of the conical sealing connection sleeve, and an internal thread layer is arranged on the inner wall of the conical sealing connection sleeve.

[0009] As a further solution of the present invention: the jet head is connected to the core tube by threaded fitting, and the inner diameters of the jet head are inconsistent, and the inner diameter of the connection between the jet head and the core tube is larger than the inner diameter of the outer end of the jet head.

[0010] As a further solution of the present invention: the main pipeline and the transition pipe are connected by threaded fitting, and the fixing bolts pass through the interior of the conical sealing connection sleeve to connect the main pipeline and the transition pipe.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The stacked tower jet soot blower is an optimized and improved version of the traditional soot blower structure. It uses compressed air as the medium and is fixed in the horizontal flue behind the flame deflection angle, only blowing away the accumulated soot.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] See also Figure 1-5 The present embodiment provides a stacked tower jet soot blower, comprising a transition pipe 1, a core pipe 2 and a main cavity 5. The transition pipe 1 is vertically installed on the main pipeline 6. The core pipe 2 is provided at the lower position of the transition pipe 1. A plurality of evenly distributed jet heads 3 are provided on the outer wall of the core pipe 2. The lower position of the core pipe 2 is connected to the main cavity 5, and a sealing gasket 4 is provided at the connection position between the core pipe 2 and the main cavity 5.

[0024] The stacked tower jet sootblower is typically installed on the wall tube covering the bottom of the horizontal flue. A purge medium at a certain pressure enters the interior of the core tube 2 through the main pipes 6 on both sides of the boiler A and B, and then enters the jet head 3 through the core tube 2. The jet sootblower uses the high-speed airflow ejected from the jet head 3 to guide the medium and sweep away the accumulated ash, coke, and slag in the horizontal flue. During operation, the device loosens and lifts the ash accumulated in the horizontal flue. Some of the lifted ash is carried away by the flowing flue gas and facilitates the sonic sootblower to vibrate and remove the accumulated ash. This solves the problems of ash, coke, and slag accumulation in the horizontal flue area.

[0025] Furthermore, the transition duct 1 includes a transition gasket 101, a transition cavity 102, a mounting chuck 103, and a conical sealing connection sleeve 104. The transition gasket 101 is disposed at the rightmost position of the transition duct 1, and the right end of the transition gasket 101 is connected to the core pipe 2. The transition cavity 102 is disposed to the left of the transition gasket 101. The mounting chuck 103 is disposed to the left of the transition cavity 102. The mounting chuck 103 is equipped with a conical sealing connection sleeve 104, and the mounting chuck 103 is connected to the main pipe 6 via the conical sealing connection sleeve 104. The transition duct 1 secures the stacked tower jet sootblower to the main pipe 6, improving internal sealing efficiency while further reducing subsequent component maintenance costs.

[0026] Furthermore, the conical sealing connection sleeve 104 includes an external interface 201, an elastic stopper 202, and an internal thread layer 203. The conical sealing connection sleeve 104 is a conical hollow structure and is disposed on the mounting chuck 103. The external interface 201 is disposed at its upper end. A plurality of evenly distributed elastic stoppers 202 are disposed on the outer wall of the conical sealing connection sleeve 104. The inner wall of the conical sealing connection sleeve 104 is provided with an internal thread layer 203. The conical sealing connection sleeve 104 is sleeved on the mounting chuck 103. Compared with traditional bolt-fixed connections, the conical sealing connection sleeve 104 can improve the sealing performance of its fixed position, thereby further ensuring the working efficiency of the device during use.

[0027] Furthermore, the jet head 3 is connected to the core tube 2 by threaded engagement, and the inner diameters of the jet head 3 are inconsistent, with the inner diameter at the connection between the jet head 3 and the core tube 2 being larger than the inner diameter of the outer end of the jet head 3. This arrangement of the jet head 3 can increase the air flow rate, thereby further improving the sootblowing efficiency.

[0028] Furthermore, the main pipe 6 is connected to the transition pipe 1 via a threaded connection, and a fixing bolt passes through the interior of the conical sealing connection sleeve 104 to connect the main pipe 6 to the transition pipe 1. By providing the conical sealing connection sleeve 104 on the mounting chuck 103 and fixing the main pipe to the mounting chuck with bolts, the fixed position and fixation can be improved.
