Description

Liquid sealing device with filtering function

Technical Field

The utility model belongs to the technical field of the liquid seal device, concretely relates to take filterable liquid seal device.

Background

The stainless steel continuous production line uses 1 mixed acid mist washing tower and 1 sulfuric acid mist washing tower respectively, and the material is PPH (homo-polypropylene). In the production process, waste gas containing nitric acid, hydrofluoric acid and sulfuric acid entering from a position 1.2 meters away from the bottom of the spray tower is sprayed and absorbed by water from the top of the spray tower, and the water is automatically supplemented once every 2 hours. Due to the corrosion of the pall ring as a packing in the column by the acid-containing solution for a long time, the crushed matter floats on the liquid surface at the bottom of the column. Overflow can appear when moisturizing, and broken thing flows out along with the overflow pipe.

The utility model discloses a grant publication No. CN 203711024U's utility model discloses a take low level receiving kettle of liquid seal, the receiver tube has the liquid seal device of U type. Because former overflow pipe design is "U" type, plays the effect of sealed waste gas, the drawback that this kind of design exists is, can block up "U" type pipe when the broken thing of stopping material is more or long-term use, causes the unable normal discharge of make-up water in the scrubbing tower, and unnecessary shower water can get into the acid mist pipeline and cause whole acid mist processing system to shut down, the environmental protection accident appears, brings the potential safety hazard for the enterprise.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, a liquid seal device with a filter comprises an inner cylinder 1 and an outer cylinder 2, wherein the bottom of the inner cylinder 1 is closed, the top of the inner cylinder 1 is open, and two V-shaped notches 6 are symmetrically arranged at the top of the inner cylinder 1. The diameter and the height of the outer cylinder 2 are respectively 5-10cm greater than the diameter and the height of the inner cylinder 1, the bottom of the outer cylinder 2 is closed, a through hole with the same diameter as the inner cylinder 1 is formed in the bottom of the outer cylinder 2, and the inner cylinder 1 is sleeved in the through hole and is welded and fixed with the outer cylinder 2. The outer cylinder 2 is sleeved into the inner cylinder 1 from the bottom end, the bottom of the outer cylinder 2 is welded on the outer wall of the inner cylinder 1, and the welding position on the outer wall of the inner cylinder 1 is not lower than one half of the height of the inner cylinder 1.
