Detailed Description
In order to facilitate understanding of the present invention, the present invention will be described more fully with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 2 to 4, in the present embodiment, a gas-tar separator includes a separator body 1, a cross filter screen 2 and a vertical filter screen 3 disposed in an inner cavity of the separator body 1, an air inlet pipe 6, and an air outlet pipe 7. An air inlet 11 is opened on the side wall of the separator body 1 and an air outlet 12 is opened on the top end of the separator body 1.
The cross filter screen 2 and the vertical filter screen 3 of this embodiment adopt the tubular structure that stainless steel material made, namely, open on the global of cross filter screen 2 and vertical filter screen 3 has the filtration hole of a plurality of evenly arranged. The air inlet 11 extends across the sieve 2 to be plugged into the interior of the separator body 1 in a horizontal arrangement, thereby realizing the air inlet 11 extending horizontally across the sieve 2 outwardly through the side wall of the separator body 1. The vertical filter screen 3 penetrates through the air outlet 12 from top to bottom to be inserted into the inner cavity of the separator body 1 and vertically arranged, so that the vertical filter screen 3 vertically extends to penetrate through the air outlet 12 preset on the top end of the separator body 1, and is vertically arranged with the vertical filter screen 3 across the filter screen 2; by adopting the inserting and penetrating installation mode, the transverse filter screen 2 and the vertical filter screen 3 can be movably and detachably installed on the separator body 1, the transverse filter screen 2 and the vertical filter screen 3 can be replaced, and the operation is very simple.
Therefore, the coal gas sent from the gas inlet 11 enters the inner cavity of the separator body 1 after being subjected to primary filtration through the transverse filter screen 2 pair, is discharged upwards through the gas outlet 12 after being subjected to secondary filtration through the vertical filter screen 3, and most of dust and tar contained in the coal gas are filtered by adopting the secondary filtration mode so as to send the coal gas meeting the requirements.
In addition, the filtered waste tar can be gradually accumulated at the bottom of the inner cavity of the separator body 1 due to the dead weight of the waste tar, and therefore the diffusion valve 4 arranged at the bottom end of the separator body 1 in the embodiment can discharge the waste tar accumulated at the bottom of the inner cavity through the filtering treatment by opening the diffusion valve 4, so that the waste tar can be timely discharged and cleaned in the use process of the separator, and the operation is convenient and simple.
