Embodiment 1

[0035] figure 1 It is a schematic diagram of the slag remover provided by Embodiment 1 of the present invention. Embodiment 1 of the present invention provides a slag remover 10 , which includes a filter device 1 and a connecting pipe 2 . The filter device 1 has a closed cavity 11 capable of accommodating liquid, and an outlet 12 is opened on the upper part of the closed cavity 11, and the outlet 12 is used to output filtered gas; an inlet 13 is opened on the lower part of the closed cavity 11, and the inlet 13 is used to input the gas to be filtered; the height of the connecting pipe 2 is greater than the liquid level 3 of the liquid contained in the closed cavity 11, one end of the connecting pipe 2 is sealed with the inlet 13, and the other end is used for the output port of the blowout preventer Sealed connection.

[0036] The slag remover provided in Embodiment 1 of the present invention has a filter device and a connecting pipe, and the connecting pipe can transport th...

Embodiment 2

[0038] figure 2 Schematic diagram of the slag remover provided for the second embodiment of the present invention. Embodiment 2 of the present invention is based on the technical solution of Embodiment 1. Preferably, the number of filter devices 1 is at least two, each filter device 1 is sealed in sequence, and the outlet 12 and inlet of adjacent filter devices 1 13 connected to each other. That is, the inlet 13 of the first filter device 1 is connected to one end of the connecting pipe 2 for inputting the gas to be filtered into the filter device 1, and the outlet 12 of the first filter device 1 is connected to the inlet 13 of the second filter device 1 , the outlet 12 of the second filtering device 1 is connected with the inlet 13 of the third filtering device 1, and so on.

[0039] Setting multiple filtering devices can improve the filtering effect.

[0040] Further, the upper end of the closed cavity 11 is provided with a liquid inlet pipe 14, and the liquid inlet pipe...

Embodiment 3

[0044] image 3 It is a schematic diagram of the slag remover provided by Embodiment 3 of the present invention. Embodiment 3 of the present invention is based on the technical solution of Embodiment 1. It is preferred that the filter device 1 further includes a first filter screen 18, which is fixedly arranged on the inner wall of the closed cavity 11, intercepting In the gas flow path, and the liquid level 3 of the liquid is higher than the installation position of the first filter 18 .

[0045] Setting the first filter screen and making the liquid level of the liquid higher than the installation position of the first filter screen can effectively prevent coal dust in the solution from being suspended on the surface of the solution.

[0046] Further, the filter device also includes a second filter screen 19, which is fixedly arranged on the inner wall of the closed cavity 11, intercepted in the flow path of the gas laterally, and the liquid level 3 of the liquid is lower th...

Abstract

The invention discloses a cleaner unit and a gas extraction system. The cleaner unit comprises a filter unit and a connection tube. The filter unit comprises a sealed cavity capable of accommodating liquid, an outlet arranged on the upper part of the sealed cavity for discharging filtered gas, and an inlet arranged on the lower part of the sealed cavity for feeding to-be-filtered gas. The height of the connection tube is larger than the height of liquid level in the sealed cavity. One end of the connection tube is in airtight connection with the inlet, and the other end is in airtight connection with the outlet of a blowout preventer unit. The scummer has simple structure and prevents blocking of gas extraction pipelines by coal dust, thus improving gas extraction rate.

Description

technical field [0001] The invention relates to mechanical structure technology, in particular to a slag remover and a gas extraction system. Background technique [0002] In the process of coal mine production, a large amount of gas is often produced. In order to ensure the safety of the system, it is necessary to set up a gas drainage system to timely extract the gas generated during underground operations. [0003] The existing gas drainage system includes a drainage pipe network and a blowout prevention device. The blowout prevention device is arranged at the entrance of the gas drainage pipe network to suck the gas in the holes into the gas drainage pipe network and prevent the gas from spraying. Injury and gas overrun. [0004] There are at least the following problems in the prior art: the gas inhaled by the blowout preventer usually contains a large amount of coal dust, which will block the gas drainage pipe network, thereby greatly affecting the extraction efficien...
