Abstract

FIELD: gas cleaning apparatus; oil, gas and chemical industries.

SUBSTANCE: proposed apparatus has housing with inlet and outlet pipe unions, upper cover connected with outlet pipe union and lower cover provided with drain pipe, standard access hole for mounting and dismantling louver-type separating components; mounted between upper and lower covers is welded rectangular framework with seats-recesses where louver stacks are secured; sizes of these stacks are unified for mounting and dismantling through access hole. Sizes of side walls of welded framework and number of separating stacks are dictated by flow rate of gaseous medium through apparatus.

Description

The invention relates to devices for separating liquid and solid impurities from gas. The invention can be used in the oil, gas, chemical and other industries.

A known separator for cleaning gases from mechanical impurities and liquids, including a cylindrical body and a tray with a drain pipe and a lid installed in it, between which there is a packet of louvered radial corrugated plates with a variable height of corrugations increasing in the direction of gas flow [1]. The cover is made with a Central hole and has a diameter equal to the diameter of the separator housing, and the pan is made with a diameter smaller than the diameter of the housing, and forms with it an annular channel for the passage of gas flow. The width of the corrugation bases is made decreasing from the periphery to the center.

The disadvantage of this design is the difficulty of assembling the corrugated plates with a variable height of the corrugations in an annular louvre bag and attaching the plates at the ends to the lid and pallet, as well as the non-repairability of the structure, as in the case of clogging of the corrugated plate channels or their partial destruction (corrosion, breakage, etc.), it is necessary to cut the separator body and re-manufacture and mount the ring package in the apparatus.

A known design of a louvered gas separator for cleaning gas from liquid and solid impurities, comprising a vertical housing with inlet and outlet fittings and a chipper from louvre plates of a wave-like profile assembled in an annular section [2], adopted as a prototype. The annular section consists of a lower ring, the outer diameter of which is equal to the inner diameter of the separator body, and an upper cover, the diameter of which is approximately 200 mm less than the diameter of the separator body. Two ring combs are welded concentrically on the lower ring, the slots in which are made so that after installing the lower ends of the louvre plates in them, wave-like channels are formed between the plates. In the slot of the upper ends of the louvre plates, the same two combs are installed concentrically with the lower one, and the upper cover is placed on them. An annular section of louvre plates is installed in the cage of the separator, and its lower ring is welded to the casing along the outer diameter. When gas passes through the wave-like channels between the louvre plates due to inertia forces, separation of heavier liquid and solid impurities from the gas occurs. The purified gas through the annular gap between the separator housing and the top cover leaves through the outlet fitting from the apparatus.

The disadvantages of this design of the louvre separator are the complexity and complexity of the assembly of the annular section, its inseparability after installation in the apparatus, making it non-repairable.

The objective of the invention is to increase the manufacturability of the manufacture and installation of apparatus for cleaning gas from liquid and solid impurities, its maintainability.

The problem is solved due to the fact that in the apparatus containing the housing with inlet and outlet fittings, the upper cover connected to the output fitting, and the bottom with a drain pipe, a standard manhole for mounting and dismounting the louvre-type separation elements, between the upper and lower the lids are fitted with a welded rectangular frame with nests-niches in which louvred bags in rectangular frames are fixed with the possibility of replacement.

Each louvre bag is made in the form of a spatial lattice, which is assembled from wave-shaped plate elements (louvre plates), assembled into a bag with a certain step and fixed (on welding) in a rectangular frame. The size of the rectangular frame of the separation bag is unified and is determined by the possibility of transporting the separation bag inside the apparatus for mounting-dismantling through the standard hatch-hole of the apparatus. The size of the sides of the welded rectangular frame, and accordingly the number of separation bags placed in the niches of the frame, is determined by the flow rate of the gaseous medium through the apparatus.

Figure 1 schematically shows the proposed apparatus of the vertical type, longitudinal section, figure 2 - the proposed apparatus of the horizontal type, longitudinal section, figure 3 - the design of the package of louvre plates assembled with a certain step and fixed in a rectangular frame.

The design of the proposed apparatus includes a housing 1, an inlet fitting 2, an outlet fitting 3, a rectangular frame with sockets-niches 4, louvres 5, upper 6 and lower 7 covers, a standard manhole 8.

The device operates as follows.

Gas enters the apparatus through the inlet nipple 2, passes through the louver packages 5 installed in a rectangular frame with sockets-niches 4, and through the outlet nipple 3 leaves the apparatus. With the passage of gas through the curved channels of the louver packages, the separation of heavier liquid and solid particles from the gas takes place. The solids are washed out with a separated liquid and a gas stream from curved channels to the lower part of the frame and then through the drain pipe to the lower part of the apparatus.

The proposed welded rectangular frame with upper and lower covers can be installed both in existing devices (during the reconstruction of failed or inefficient devices), and in the design and manufacture of new devices (separators, columns, absorbers, etc.), where high-quality purification of gaseous media from liquid and solid impurities.
