Abstract
The invention relates to a switching condenser with a spraying system. The switching condenser comprises a condenser shell, a phthalic anhydride header pipe, phthalic anhydride spraying pipes and a purging gas ingress pipe. The phthalic anhydride header pipe stretches into the condenser shell from the exterior of the condenser shell; the part, located outside the condenser shell, of the phthalic anhydride header pipe is connected with the purging gas ingress pipe; the part, stretching into the condenser shell, of the phthalic anhydride header pipe is connected with the multiple phthalic anhydride spraying pipes; a spraying distributor is arranged on the pipe wall of each phthalic anhydride spraying pipe. Compared with the prior art, the spraying system is arranged inside the switching condenser, so that phthalic anhydride, high polymers and other impurities condensed on dead angles inside the switching condenser, the wall of a container and gaps of finned pipes can be effectively cleaned.
Description
Technical field
The present invention relates to a kind of switch condenser, especially relate to a kind of switch condenser with spray system.
Background technology
At present, it is cooling that the phthalic anhydride industry generally uses switch condenser to carry out reacted gas, to reach the reservation raw phthalic anhydride, separates the purpose of unnecessary air and light component.The operation of switch condenser has been played vital effect to production process, in practice, the inner dead space of switch condenser, chamber wall and finned tube gap etc. are located, the impurity such as phthalic anhydride and high polymer that often easily condense, caused the impact of heat exchanging, is the destabilizing factor of producing.
Existing switch condenser has housing conduction oil or steam tracing more, and the phthalic anhydride that the elimination chamber wall is condensed has certain effect.But the contact area of heat tracing pipe is limited, for the impurity of some dead angles and finned tube gap location, be difficult to have effect.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of switch condenser with spray system in order to overcome the defect that above-mentioned prior art exists, and this switch condenser can effectively be removed the impurity such as the phthalic anhydride locating to condense in inner dead space, chamber wall and finned tube gap etc. and high polymer.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of switch condenser with spray system, comprise condenser shell, the phthalic anhydride house steward, phthalic anhydride shower and purge gas ingress pipe, described phthalic anhydride house steward stretches into inside by the outside of condenser shell, the phthalic anhydride house steward is positioned on the part of condenser shell outside and connects the purge gas ingress pipe, the part that stretches into condenser shell inside connects a plurality of phthalic anhydride showers, the tube wall of each phthalic anhydride shower is provided with the spray distributor, by in inside, spray system being set, can effectively remove inner dead space, the impurity such as the phthalic anhydride that chamber wall and finned tube gap etc. are located to condense and high polymer.
Described a plurality of phthalic anhydride shower is arranged in parallel, and is uniformly distributed in the inside of condenser shell, simultaneously by being provided with the spray distributor on the tube wall at the phthalic anhydride shower, while making spray, can cover switch condenser inside comprehensively, reaches good cleaning effect.
Described purge gas ingress pipe is vertically connected at the phthalic anhydride house steward, by the purge gas ingress pipe is set, when phthalic anhydride, in shower inside, condense while blocking, import purge gas and can guarantee that the shower use is unimpeded, and purge gas can be used the gas commonly used in chemical plant, as compressed air, nitrogen etc., save maintenance cost.
Described phthalic anhydride house steward is connected with a plurality of phthalic anhydride showers by the tube connector of a horizontally set.
Compared with prior art, the present invention has the following advantages:
One, wide coverage: utilize the spray distributor, during spray, can cover switch condenser inside comprehensively, compare housing companion heat and more have superiority.
Two, effective: as can to accompany heat to be used in conjunction with housing, effectively the residual phthalic anhydride that condenses of abatement apparatus wall and place, dead angle.
Three, clog-free: as by importing purge gas, can to prevent that shower and spray distributor from blocking.
Four, the utilization of resources is abundant: the present invention sprays phthalic anhydride and utilizes original raw phthalic anhydride and chemical plant gas commonly used, effectively utilizes existing resource.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
The schematic diagram that Fig. 2 is another visual angle of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As described in Figure 1, a kind of switch condenser with spray system, comprise condenser shell 1, phthalic anhydride house steward 2, phthalic anhydride shower 3 and purge gas ingress pipe 5, phthalic anhydride house steward 2 stretches into inside by the outside of condenser shell 1, and liquid phthalic anhydride is delivered in switch condenser.Phthalic anhydride house steward 2 stretches into the part of condenser shell inside by 3 phthalic anhydride showers 3 of tube connector 6 connections of a horizontally set, these phthalic anhydride showers 3 are evenly distributed on the inside of condenser shell 1, and spray distributor 4 is set on its tube wall, can cover switch condenser inside while making spray comprehensively, reach good cleaning effect.
Phthalic anhydride house steward 2 is positioned on the part of condenser shell outside, the vertical purge gas ingress pipe 5 that connects, when phthalic anhydride, in shower inside, condense while blocking, import purge gas and can guarantee that the shower use is unimpeded, and purge gas can be used the gas commonly used in chemical plant, as compressed air, nitrogen etc., save maintenance cost.
Owing to being arranged on spray system, can effectively remove the impurity such as the phthalic anhydride locating to condense in inner dead space, chamber wall and finned tube gap etc. and high polymer, if be used in conjunction with the tracing system of condenser shell, remove effect better.
