Abstract

The invention discloses an improved pressure release device for a reaction vessel. The improved pressure release device is used for a high pressure reaction vessel, a rectifying still and other chemical environmental protection devices, has the effect of releasing pressure of high pressure gasses in the vessel. The improved pressure release device is characterized in that: labyrinth partitions in a pressure release tank are removed and replaced by a wire mesh demister which is made with multi-layer woven metal wire meshes with 40-400 meshes; when releasing pressure, the released gasses and foam press the wire mesh demister, high pressure gasses repeatedly impact metal wire meshes to release the potential energy, while foam bursts continuously because of infiltration effect of the serried meshes, a few solid particles in the materials are sequestered simultaneously, thus the gasses in the foam are released, and the material foam does not rush out with the released gasses.

Description

A kind of modified agitated reactor is used pressure relief device

Technical field:

A kind of modified agitated reactor is used pressure relief device, is used for chemical industry environmental protection equipment such as autoclave, rectifying still, plays the effect of letting out except that still inner high voltage gas pressure.

Background technology:

Some agitated reactors or some rectifying stills are because the needs of chemical industry or environmental protection reaction process are usually worked under the condition of high pressure; When reaction finishes row's material or turnaround of unit, steadily let out the significant process that just becomes the realization safety in production except that the still internal pressure, for this reason; People's specialized designs polytype agitated reactor pressure relief device, at present utilization is the labyrinth type pressure relief device the most widely, so-called labyrinth type pressure relief device promptly is in pressure release ladle bowl main body, to establish a large amount of dividing plates; Between the dividing plate, be provided with a large amount of gaps, gapped staggered rows cloth between dividing plate and the pressure release ladle bowl inwall; Form the labyrinth that gas is released, gases at high pressure are tortuous revolution from the labyrinth, and its high pressure potential energy has just obtained discharging more fully; Very steady when it flows out pressure relief device, do not cause production hidden danger because of its HTHP entirely.Though this device pressure release efficient is high; Stable performance; But, when handling some and viscosity is arranged or contain the impurity of small solid particle such as municipal wastewater, trade effluent etc., there is treating material to produce foam unavoidably and goes out with gas because its road, crack, labyrinth still can pass by contained foam in the material; Cause potential faults, also polluted working environment simultaneously.

Summary of the invention:

The problem that is prone to take out of material when overcoming original labyrinth type pressure relief device pressure release specially proposes a kind of modified agitated reactor and use pressure relief device, and its main implementation is such: the interior maze partition plates of cancellation pressure release jar; Change and establish wire mesh demister, said wire mesh demister is formed by the braiding of multilayer 40～400 order woven wires, can be fixed in pressure relief device inside by fixed support; Its periphery closely connects in pressure release jar inwall, clogs the gas path that directly leaks, when pressure release work of the present invention; Pressure release gas and foam punching press wire mesh demister, wherein gases at high pressure repeated stock on each woven wire, its potential energy obtains discharging; And foam constantly breaks owing to the immersional wetting of intensive silk screen, and the small amount of solid particle in the material also is detained simultaneously; Thereby the gas in the foam is disengaged, and the material foam is no longer gone out with pressure release gas.

Through experiment, pressure relief device according to the invention can make and release the foam minimizing more than 98%.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present invention;

Accompanying drawing 2 is original pressure relief device structural representations;

Accompanying drawing 3 is mounting structure sketch mapes of the present invention; Wherein:

(1) pressure relief device tank body, (2) wire mesh demister, (3) fixed support, (4) exhaust outlet, (5) air inlet, (6) maze partition plates, (7) agitated reactor.

The specific embodiment:

Shown in accompanying drawing 2, original labyrinth type pressure relief device promptly is in pressure release ladle bowl (1) main body, to establish a large amount of separated labyrinth plates (6), between the dividing plate (6); Be provided with a large amount of gaps between dividing plate (6) and pressure release ladle bowl (1) inwall, gapped staggered rows cloth forms the labyrinth that gas is released; Gases at high pressure are tortuous revolution from the labyrinth; Its high pressure potential energy has just obtained discharging more fully, and is very steady when it flows out pressure relief device (1), can not cause production hidden danger because of its HTHP.Though this device pressure release efficient is high; Stable performance; But, when handling some and viscosity is arranged or contain the impurity of small solid particle such as municipal wastewater, trade effluent etc., there is treating material to produce foam unavoidably and goes out with gas because its road, crack, labyrinth still can pass by contained foam in the material; Cause potential faults, also polluted working environment simultaneously.

Shown in accompanying drawing 1, the present invention cancels maze partition plates (6) in the pressure release jar, changes and establishes wire mesh demister (2); Said silk screen foam removal (2) device is formed by the braiding of multilayer 40～400 order woven wires, can be fixed in pressure relief device (1) inside by fixed support (3), and its periphery closely connects in pressure release jar (1) inwall; Clog the gas path that directly leaks, when pressure release work of the present invention, pressure release gas and foam impact wire mesh demister (2); Wherein gases at high pressure are gone up repeated stock at each woven wire (2), and its potential energy obtains discharging, and foam is because the immersional wetting of intensive silk screen (2); Constantly break; Small amount of solid particle in the material also is detained simultaneously, thereby the gas in the foam is disengaged, and the material foam is no longer gone out with pressure release gas.

Shown in accompanying drawing 3, modified agitated reactor according to the invention is installed on the agitated reactor (7) with pressure relief device pressure release tank body (1), when reaction finishes row's material or turnaround of unit, steadily lets out except that the still internal pressure.
