Abstract
The utility model discloses a first-stage desorption tower for purifying methane. The first-stage desorption tower comprises a flash steam outlet, a relief valve connector, a drain hole, a saddle and a barrel, wherein seal heads are arranged at the two ends of the barrel; the relief valve connector and the flash steam outlet are arranged on the top of the barrel; the drain hole is arranged at the bottom of the barrel; a water inlet is arranged at the top of one side of the barrel; the seal head connected with the other side of the barrel is provided with a water outlet at the middle lower part; the barrel is internally provided with a baffle plate; and the saddle is arranged under the barrel. Compared with a vertical tank, a horizontal tank is capable of reducing the equipment height, saving energy consumption, greatly lowering the equipment manufacturing cost and saving the manpower and equipment installation cost; the barrel is internally provided with the baffle plate, so that the travel distance of fluid is prolonged within the limited space of the barrel, the colliding frequency and the baffling frequency of the fluid and the baffle plate are increased, the desorption effect is improved, and filler and a demister are not needed.
Description
Technical field
The utility model belongs to mechanical manufacturing field in methane purification purification, is specifically related to a kind of one-level desorber for methane purification.
Background technology
In methane purification, decarburization is to utilize the different solubility of methane and carbon dioxide in cleaning solution, under certain operating condition on absorption tower to realizing the absorption of cleaning solution to carbon dioxide, then the desorb by is progressively by the release of carbonate dioxide in cleaning solution, and cleaning solution returns in absorption tower and realizes and recycling.At present mainly contain following two kinds of forms for the one-level desorber of methane purification: the one, vertical desorber, the 2nd, horizontal desorption tower.Vertical desorber, tower height, fluid need overcome the resistance of tower height while conveying, need the auxiliary filler that uses in tower, and investment is large, and energy consumption is high; Horizontal desorption tower, simple in structure, do not need to use filler, tower is low, and energy consumption is low, small investment.
Summary of the invention
The purpose of this utility model is to provide a kind of desorption ability high, the one-level desorber for methane purification that energy consumption is low.
For achieving the above object, the technological means that the utility model is taked is, a kind of one-level desorber for methane purification, comprise cylindrical shell, cylindrical shell two ends are respectively equipped with end socket, and cylindrical shell one side roof part is provided with water inlet, cylindrical shell opposite side top is provided with flashed vapour outlet, the outside of position, cylindrical shell opposite side end socket middle and lower part is provided with delivery port, and cylinder body bottom is provided with discharge outlet and saddle, and inner barrel is provided with deflection plate.
Described cylindrical shell top is provided with relief valve connection.
Described cylindrical shell top is provided with manhole.
Described cylindrical shell is cylindrical structural, and end socket is elliposoidal structure.
Described deflection plate is polylith, in cylindrical shell, is staggered.
Delivery port is deep into the bottom position of cylindrical shell by connected pipe.
Described saddle can be set to multiple as required.
The utility model also can increase liquid level gauge, realizes the automatic control to liquid level in tower.
The beneficial effect that the utility model produces is, adopts the structure of horizontal tank, and simple in structure, the design size that can dwindle tank body, reduces manufacturing cost, maintains easily; Horizontal tank has reduced device height compared with vertical tank, saves energy consumption, greatly reduces the cost of equipment simultaneously, has saved artificial and equipment installation cost; By the deflector means of inner barrel, in the limited space of cylindrical shell, extend the stroke of fluid, increase collision and the baffling number of times of fluid and deflection plate, thereby raising desorption effect need not arrange filler and demister.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is top view of the present utility model;
Fig. 3 is right view of the present invention.
The specific embodiment
As Figure 1-3, for the one-level desorber of methane purification, tower body is made up of cylindrical shell 12 and two end sockets 13, described tower body is horizontal type structure, cylindrical shell 12 tops are provided with water inlet 1, flashed vapour outlet 4, relief valve connection 3 and manhole 2, tower body bottom is provided with discharge outlet 5, and end socket lower end is provided with delivery port 6.There is the deflection plate 7,8,9 of three staggered discharges in tower body inside, the rich solution that discharge on absorption tower is reduced pressure after certain pressure and is entered in tower body by water inlet 1 by choke valve, in tower body, pass through deflection plate baffling, gas-liquid obtains the separation of very big degree, gas after desorb exports 4 by flashed vapour and discharges, liquid is discharged by delivery port 6, and after device is stopped using, the liquid in tower body is discharged by discharge outlet 5.Safety valve guarantees that tower internal pressure is maintained within a certain range, and manhole 2 is convenient to be keeped in repair tower body.Tower body bottom is provided with saddle 10,11.
