Abstract

The utility model relates to an improved reactor pressure relief device, which is used for environmental protection equipment, such as a high-pressure reactor, a rectifying kettle, and the like for the chemical industry and plays a role of relieving the pressure of high-pressure gas in the reactor. The improved reactor pressure relief device is mainly implemented in such a way that a maze partition plate in a pressure relief tank is replaced by a wire mesh demister; the wire mesh demister is formed by knitting multiple layers of metal wire meshes in 40-400 meshes; during pressure relief work, pressure relief gas and foams stamp the wire mesh demister, wherein the high-pressure gas repeatedly impacts all the metal wire meshes, and the potential energy of the high-pressure gas is released; the foams are continuously broken under the soaking action of the dense wire meshes; a small number of solid particles in materials are simultaneously retained, the gas in the foams are released, and thus, the foams of the materials do no fly out along with the pressure relief gas.

Description

A kind of modified reactor pressure relief device

Technical field:

A kind of modified reactor 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 reactors or some rectifying stills, because the needs of chemical industry or environmental protection reaction process, usually under the condition of high pressure, work, 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 reactor pressure relief device, utilization is the labyrinth type pressure relief device the most widely at present, so-called labyrinth type pressure relief device promptly is to establish a large amount of dividing plates in pressure release ladle bowl main body, between the dividing plate, is provided with a large amount of gaps between dividing plate and the pressure release ladle bowl inwall, institute is gapped staggered, 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 height, stable performance, but because its road, crack, labyrinth still can be passed by contained foam in the material, when handling some and viscosity arranged or contain the impurity of small solid particle such as municipal wastewater, trade effluent etc., having treating material to produce foam unavoidably goes out with gas, cause potential faults, also polluted working environment simultaneously.

Summary of the invention:

The problem of easily taking material out of when overcoming original labyrinth type pressure relief device pressure release, a kind of modified reactor pressure relief device of special proposition, its main implementation is such: maze partition plates in the cancellation pressure release jar, change and establish wire mesh demister, described 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, clog the gas path that directly leaks, when the utility model pressure release is worked, 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 described in the utility model can make and release the foam minimizing more than 98%.

Description of drawings:

Accompanying drawing 1 is the utility model structural representation;

Accompanying drawing 2 is original pressure relief device structural representations;

Accompanying drawing 3 is the utility model mounting structure schematic diagrames; 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) reactor.

The specific embodiment:

As shown in Figure 2, original labyrinth type pressure relief device promptly is to establish in pressure release ladle bowl (1) main body in a large number every labyrinth plate (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, institute is gapped staggered, 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 height, stable performance, but because its road, crack, labyrinth still can be passed by contained foam in the material, when handling some and viscosity arranged or contain the impurity of small solid particle such as municipal wastewater, trade effluent etc., having treating material to produce foam unavoidably goes out with gas, cause potential faults, also polluted working environment simultaneously.

As shown in Figure 1, maze partition plates (6) in the utility model cancellation pressure release jar, change and establish wire mesh demister (2), described 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), its periphery closely connects in pressure release jar (1) inwall, clog the gas path that directly leaks, when the utility model pressure release is worked, 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.

As shown in Figure 3, modified reactor described in the utility model is installed on the 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.
