Description

Technical Field

[0001] This utility model relates to the field of gas furnace equipment modification technology, and more specifically to a gas venting bell tar collection structure. Background Technology

[0002] A gas venting device is a short pipe with an on / off valve and a rain cap at the top. Gas venting devices are typically installed at the end of gas pipelines, the top of gas storage and transportation equipment, and before the valve inlet of gas pipelines. In use, the valve on the gas venting device is operated, but normally the valve is closed.

[0003] The venting bell is an important safety feature in gasifier accessories. During gasifier operation, emergency power outages and start-up shutdowns are inevitable. If a power outage occurs suddenly during operation, gas output will be interrupted. The venting bell serves to release gas during hot standby, gas outages, or emergency power failures. Furthermore, during the start-up and shutdown processes of the gasifier, if the generated gas is substandard, it needs to be vented.

[0004] However, gas venting devices are usually installed in the open air, with the vent opening to the atmosphere. During the venting process, the tar carried by the gas will drift with the wind, resulting in a poor environment around the equipment and posing a great environmental hazard. Although the vent (top) of the gas venting device has a "rain cap", the function of this "rain cap" is mainly to solve the problem of rain protection for the venting device, and it does not have a good function of collecting tar. Utility Model Content

[0005] The purpose of this utility model is to provide a tar collection structure for a gas venting bell jar in order to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a gas venting bell jar tar collection structure, comprising a venting pipe and a rainproof cap, wherein the rainproof cap is located above the venting opening of the venting pipe, and a conical cap for collecting tar is provided inside the rainproof cap, wherein the bottom opening edge of the conical cap is fixedly connected to the inner wall of the rainproof cap, and an annular groove is fixedly connected around the bottom opening of the rainproof cap, wherein several through holes are provided on the side of the annular groove near the venting pipe, and several through holes are fixedly connected to chutes, and the downward ends of several chutes extend to the venting opening of the venting pipe.

[0007] To facilitate the rapid flow of tar from the inner wall of the conical cap into the annular groove, the inner wall of the conical cap, as a preferred embodiment of the tar collection structure of the gas venting bell jar of this utility model, is provided with multiple guide lines.

[0008] To facilitate the rapid flow of tar from the annular groove into the chute, the bottom surface of the annular groove is inclined, which is the preferred feature of the tar collection structure of the gas venting bell jar of this utility model.

[0009] To enhance the stability of the tar collection structure and the venting port installation, as a preferred embodiment of the tar collection structure of the gas venting bell jar of this utility model, the lower ends of the plurality of chutes are fixedly connected with limiting rings, and the limiting rings are located inside the venting port of the venting pipe.

[0010] In order to fix the position of the tar collection structure and the venting pipe, as the preferred embodiment of the tar collection structure of the gas venting bell jar of this utility model, several supports are fixedly installed between the outer wall of the rainproof cap and the outer wall of the venting pipe.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. When the vent pipe is working normally, the gas rises through the vent into the rainproof cap, where it is blocked by the conical cap and tar condenses. The condensed tar slides down into the annular groove by gravity, and the tar collected in the annular groove flows back into the vent pipe through several chutes, thus achieving a good gas and tar collection effect.

[0013] 2. By setting guide patterns, an inclined bottom surface of the annular groove, and inclined chute, the collected tar can flow quickly into the vent pipe, and the gaps between several chutes can avoid affecting the gas venting operation. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0021] Please see Figure 1-4 The present invention provides the following technical solution: a gas venting bell jar tar collection structure, including a venting pipe 1 and a rainproof cap 2. The rainproof cap 2 is located above the venting opening of the venting pipe 1. The interior of the rainproof cap 2 is provided with a conical cap 3 for collecting tar. The bottom opening edge of the conical cap 3 is fixedly connected to the inner wall of the rainproof cap 2. An annular groove 4 is fixedly connected around the bottom opening of the rainproof cap 2. Several through holes 401 are opened on the side of the annular groove 4 near the venting pipe 1. The several through holes 401 are all fixedly connected to a chute 5.

[0022] In this embodiment: when the vent pipe 1 is working normally, the gas rises through the vent into the rainproof cap 2, where it is blocked and condensed by the conical cap 2. The condensed tar slides down into the annular groove 4 by gravity. The inner diameter of the annular groove 4 is larger than the diameter of the vent at the top of the vent pipe 1 to prevent it from blocking the gas from rising. The tar collected in the annular groove 4 then flows back into the vent pipe 1 through several chutes 5, thereby achieving a good gas and tar collection effect.

[0023] As a technical optimization of this utility model, the inner wall of the conical cap 3 is provided with multiple guide patterns 301, the bottom surface of the annular groove 4 is inclined, and the downward end of several chutes 5 extends to the vent of the vent pipe 1.

[0024] In this embodiment, by setting the guide pattern 301, the inclined bottom surface of the annular groove 4, and the inclined chute 5, the tar that can be collected can flow quickly into the vent pipe 1, and the gaps between several chute 5 can avoid affecting the venting of gas.

[0025] As a technical optimization of this utility model, a limiting ring 501 is fixedly connected to the lower end of several chutes 5, and the limiting ring 501 is located inside the vent of the vent pipe 1.

[0026] In this embodiment: by setting the limiting ring 501 inside the vent, the position of the tar discharge end of several chutes 5 can be stably fixed, avoiding the chutes 5 from shifting, thereby improving the accuracy of the tar discharge direction.

[0027] As a technical optimization of this utility model, several brackets 6 are fixedly installed between the outer wall of the rain cap 2 and the outer wall of the vent pipe 1.

[0028] In this embodiment: several supports 6 are used to support and fix the overall tar collection structure, and a certain distance is set between each pair of adjacent supports 6 so that the gas can be released.

[0029] The working principle and usage process of this utility model are as follows: When the vent pipe 1 is working normally, the gas rises through the vent into the rainproof cap 2, where it is blocked and condensed by the conical cap 2. The condensed tar slides down into the annular groove 4 by gravity. The tar collected in the annular groove 4 then flows back into the vent pipe 1 through several through holes 401 and several chutes 5. At the same time, after the gas condenses into tar, it is discharged downward through the gaps between several chutes 5 and several supports 6, thereby completing the venting work and the tar collection work.

[0030] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
