CN203108329U - Coal tar processing tar residue filter device - Google Patents

Abstract

The utility model discloses a tar slag filter for coal tar processing to solve the problem that the tube furnace tube of the tar tube type heating furnace in the prior art is easy to block up coking. The filter is formed by connecting a first filter and a second filter in parallel, and screens are arranged in the first filter and the second filter. The utility model has the advantages that: can effectively remove the residues in the raw material tar, and avoid serious accidents caused by the tar residues entering the plunger pump oil cylinder. The novel tar residue filter is simple to manufacture, convenient to install, quick to clean, capable of being used alternately, and incapable of causing production shutdown.

Description

Coal tar processing tar residue filter device

technical field

The utility model belongs to the technical field of the chemical industry, in particular to a tar residue filter device for coal tar processing. the

Background technique

With the rapid development of the coking industry and the continuous expansion of the scale of the coking chemical industry, valuable chemical products are always favored by the market. Coal tar processing is an important processing method for the production of chemical products. The continuous and stable production of coal tar processing can avoid accidents. It is one of the important means for safe production and improving efficiency of coal tar processing enterprises. Coal tar raw material for coal tar processing contains tar residue , and some tar residue particles have a diameter of 15mm. These tar residues enter the plunger pump during tar processing and production. In the oil cylinder, the valve seat of the plunger pump is not closed tightly, and the amount of the plunger pump decreases or even does not increase. If the plunger pump does not increase the amount, the production of tar will be shut down, and in serious cases, it will cause serious accidents such as blockage and coking of the tube of the tar tube heating furnace.

Utility model content

The purpose of the utility model is to provide a coal tar processing tar slag filtering device to solve the problem in the prior art that the furnace tube of the tar tube type heating furnace is easily blocked and coked. the

The utility model adopts the following technical scheme: a coal tar processing tar residue filtering device, which is formed by parallel connection of a filter one and a filter two, and the inside of the first filter and the second filter are equipped with screens. the

The beneficial effect of the utility model is that the slag in the raw material tar can be effectively removed, and the tar slag can be prevented from entering into the plunger pump oil cylinder to cause serious accidents. The novel tar residue filter is simple to manufacture, convenient to install, quick to clean, and can be used alternately without causing production stoppage. the

Detailed ways

A tar residue filter device for coal tar processing, which is composed of a filter one 5 and a filter two 6 connected in parallel, and a screen 8 is provided inside the filter one 5 and filter two 6; one side of the screen 8 is provided with a disassembly Flange 9; the first pipeline valve 1 and the second pipeline valve 2 are respectively provided at the two ends of the filter one 5; the third pipeline valve 3 and the fourth pipeline valve 4 are respectively provided at the two ends of the filter two 6; Both ends of the first 5 and the second filter 6 are provided with flanges 7 . the

During use, open the first pipeline valve 1 and the second pipeline valve 2 before and after the filter 5, the tar flows through the filter 5, and the screen cloth 8 in the filter 5 filters the slag in the tar into the filter 5, after filtering the slag The tar is transported to the subsequent section through the delivery pump. the

When the slag in the filter needs to be cleaned after using for a period of time, you can switch to the tar filter 6 to use, that is, open the third pipeline valve 3 and the fourth pipeline valve 4 before and after the tar filter 6, and close the first pipeline valve before and after the tar filter 5. Pipeline valve 1 and second pipeline valve 2, remove flange 7 and flange 9 on one side of second pipeline valve 2, and return to equipment after cleaning. The specific cleaning and switching time can be determined according to the amount of slag in the fluid. the
