Technical Field

The invention belongs to the technical field of Venturi cyclone dust collectors, and particularly relates to a deslagging device of a Venturi cyclone dust collector.

Background

The venturi cyclone dust collector belongs to a wet dust collector, combines the functions of a venturi and the cyclone dust collector, has the characteristic of high-efficiency dust removal, can effectively remove liquid or solid particles from air flow, and can also remove gaseous pollutants.

When the Venturi cyclone dust collector is applied to the crude gas upgrading process, the phenomenon of slag accumulation needing to be cleaned often exists, after gas and liquid are mixed in the Venturi tube, particulate pollutants in the gas and part of tar can form particulate tar blocks to float on the surface of a slurry pool, and the slag is difficult to clean due to high sealing requirement.

Disclosure of Invention

The invention provides a deslagging device of a Venturi cyclone dust collector, which can collect and remove scum and has a simple structure.

The invention relates to a deslagging device of a Venturi cyclone dust collector, which mainly comprises a funnel, a gate valve, a slag liquid tank and a drain valve. The method is characterized in that: the funnel consists of a cuboid and a prismatic table structure and is arranged at the rear end of the venturi diffusion section; the gate valve is arranged on a rear pipeline of a slag outlet of the funnel and used for controlling the discharge of liquid slag; the slag liquid tank is connected with the gate valve, is of a cuboid structure and is provided with a drain outlet at the bottom; the blowoff valve is arranged on a pipeline behind the outlet of the drain outlet of the slag liquid tank to control the discharge of the slag liquid.

Furthermore, the joints of the gate valve, the blowoff valve and the pipeline are all sealed.

The invention has the following effects: 1) after the waste gas passes through the venturi, the gas-liquid mixture falls into the funnel, the precipitable particle pollutants are freely precipitated in the funnel, and the scum which is difficult to precipitate floats in the rectangular body of the funnel; 2) the deslagging device maintains a certain water level, reduces the scouring of gas mixture to the pipeline and prolongs the service life of the pipeline; 3) scum can be guided to a deslagging device in the slurry tank by a method of raising the water level of the slurry tank, so that the purpose of removing the scum in the slurry tank is achieved.

Detailed Description

The technical solution in an embodiment of the present invention will be described below with reference to the drawings in the embodiment of the present invention.

As shown in fig. 1, 2 and 3, the deslagging device of the venturi cyclone dust collector provided by the embodiment includes a funnel 1, a gate valve, a slag liquid tank 3 and a blowoff valve 5. The funnel 1 is composed of a rectangular structure and a prismatic table structure, is arranged at the rear end of a venturi tube diffusion section, is welded with the prismatic table, and is 250 multiplied by 150 multiplied by 50mm in length, width and height, 250 multiplied by 150mm in upper bottom size, 70 multiplied by 70mm in lower bottom size, 100mm in height, and welded with the upper bottom of the prismatic table; the gate valve is arranged on a pipeline behind the slag outlet 2 of the funnel and used for controlling the discharge of slag liquid, and the pipe diameter of the pipeline is DN 50; the slag liquid tank 3 is connected with the gate valve, the slag liquid tank 3 is of a cuboid structure, the length, width and height dimensions are 350 multiplied by 150mm, and a sewage outlet 4 is arranged at the bottom; and the blow-down valve 5 is arranged behind the outlet of the blow-down port 4 of the slag liquid tank 3 and controls the discharge of slag liquid in the slag liquid tank.

The joints of the gate valve, the blowoff valve 5 and the pipeline are treated by fluororubber to achieve the sealing effect.

The specific application of the invention is as follows: after the slag removing device collects slag liquid, the slag liquid can be removed by the gate valve, and gas leakage cannot occur in the process. In addition, when the scum in the slurry tank of the Venturi cyclone dust collector is more, the scum can be led to the deslagging device to be discharged by increasing the liquid level of the slurry tank. When the slag liquid tank is filled with slag liquid, the slag liquid in the slag liquid tank is controlled to be discharged through a blow-off valve 5 behind the blow-off port 4.
