Abstract

The utility model discloses a blowing type ethylene oxide storage and delivery device, which comprises an ethylene oxide measuring tank, wherein the ethylene oxide measuring tank is provided with a pressure pipe and a drain pipe which are of gas phase, and a bubbling pipe, an ethylene oxide inlet pipe and an ethylene oxide outlet pipe which are of liquid phase, a pressure valve and a drain valve are respectively arranged on the pressure pipe and the drain pipe, a bubbling valve, an inlet valve and an outlet valve are respectively arranged on the bubbling pipe, the ethylene oxide inlet pipe and the ethylene oxide outlet pipe, the device further comprises a nitrogen pipeline, an intake valve is arranged at the inlet of the nitrogen pipeline, and the nitrogen pipeline is respectively communicated with the pressure pipe and the bubbling pipe; and meanwhile, the nitrogen pipeline is also communicated with the ethylene oxide outlet pipe, a communication part is positioned at the outlet of the outlet valve, and a nitrogen valve is also arranged on one side of the nitrogen pipeline close to the ethylene oxide outlet pipe. The blowing type ethylene oxide storage and delivery device can effectively blow residual ethylene oxide in a pipeline, so the utility model has the advantages of high safety and low energy consumption.

Description

Blowing and sweeping type ethylene oxide stores feedway

Technical field

The utility model relates to a kind of ethylene oxide and stores feedway, and especially a kind of blowing and sweeping type ethylene oxide stores feedway.

Background technique

In the existing design, ethylene oxide all can have residual ethylene oxide in the pipeline after conveying.Because under hot environment, the easy phenomenon of blasting that gasifies of ethylene oxide, therefore, for the generation that prevents to explode, improve Security, it is to be in the long state of opening that the end at the whole story of pipeline must have always, increase ventilation effect, and the ethylene oxide pipeline need take the cold insulation measure, is used for reducing pipe temperature, and energy consumption is higher; In addition, ethylene oxide must be through valve sets in course of conveying, the valve sets pipeline is more, if not well design, be easy to cause the phenomenon that staggers, production accident occurs, therefore existing ethylene oxide stores feedway and exists poor stability, shortcoming that energy consumption is high, has brought inconvenience to production.

Summary of the invention

The purpose of this utility model is that the blowing and sweeping type ethylene oxide a kind of safe, that energy consumption is low that designs for the deficiency that solves above-mentioned technology stores feedway.

The designed blowing and sweeping type ethylene oxide of the utility model stores feedway, comprise the ethylene oxide measuring tank, described ethylene oxide measuring tank is provided with the forcing pipe and the emptying pipe of gas phase, and the bubbling pipe of liquid phase, ethylene oxide inlet tube and ethylene oxide outer pipe, be respectively equipped with pressurizing valve and exhaust-valve on described forcing pipe and the emptying pipe, described bubbling pipe, be respectively equipped with the bubbling valve on ethylene oxide inlet tube and the ethylene oxide outer pipe, inlet valve and outlet valve, it is characterized in that also comprising nitrogen pipeline, nitrogen pipeline inlet is provided with suction valve, and this nitrogen pipeline is connected with forcing pipe and bubbling pipe respectively; This nitrogen pipeline is connected with the ethylene oxide outer pipe again simultaneously, and connection place is positioned at the outlet port of outlet valve, also is being provided with nitrogen valve near on the nitrogen pipeline of ethylene oxide outer pipe one side.

The blowing and sweeping type ethylene oxide of the utility model gained stores feedway, after ethylene oxide has been carried, be higher than under the measuring tank pressure condition at nitrogen pressure, open this nitrogen valve, purge remaining ethylene oxide in the pipeline, can purge the ethylene oxide that remains in the pipeline clean effectively, the bubbling valve communicates liquid phase with gas phase, be higher than under the measuring tank pressure condition at nitrogen pressure, open valve and just can carry out bubbling, therefore compared with prior art have the following advantages:

1, by purging, makes in the pipeline and do not retaining ethylene oxide, avoid producing the situation that ethylene oxide is blasted because of high-temperature gasification, improve Security;

2, pipeline outer wall also need not be taked the cold insulation measure, not only reduce cost, but the while energy efficient;

3, number of tubes reduces, and prevents to reveal, and gas phase and liquid phase are installed separately, and avoids misoperation to improve aesthetics.

Fig. 1 is embodiment's 1 structural representation;

Among the figure: ethylene oxide measuring tank 1, forcing pipe 2, pressurizing valve 21, emptying pipe 3, exhaust-valve 31, bubbling pipe 4, bubbling valve 41, ethylene oxide inlet tube 5, inlet valve 51, ethylene oxide outer pipe 6, outlet valve 61, nitrogen pipeline 7, suction valve 71, nitrogen valve 72.

Embodiment

The utility model will be further described in conjunction with the accompanying drawings below by embodiment.

Embodiment 1:

As shown in Figure 1, the described blowing and sweeping type ethylene oxide of present embodiment stores feedway, comprise ethylene oxide measuring tank 1, described ethylene oxide measuring tank 1 is provided with the forcing pipe 2 and the emptying pipe 3 of gas phase, and the bubbling pipe 4 of liquid phase, ethylene oxide inlet tube 5 and ethylene oxide outer pipe 6, be respectively equipped with pressurizing valve 21 and exhaust-valve 31 on described forcing pipe 2 and the emptying pipe 3, described bubbling pipe 4, be respectively equipped with bubbling valve 41 on ethylene oxide inlet tube 5 and the ethylene oxide outer pipe 6, inlet valve 51 and outlet valve 61, also comprise nitrogen pipeline 7, nitrogen pipeline 7 inlets are provided with suction valve 71, and this nitrogen pipeline 7 is connected with forcing pipe 2 and bubbling pipe 4 respectively; This nitrogen pipeline 7 is connected with ethylene oxide outer pipe 6 again simultaneously, and connection place is positioned at the outlet port of outlet valve 61, also is being provided with nitrogen valve 72 near on the nitrogen pipeline 7 of ethylene oxide outer pipe 6 one sides.During charging, open exhaust-valve 31, make measuring tank pressure be lower than pressure of storage tank, open inlet valve 51, can carry out mass transport; When ethylene oxide uses, open suction valve 71 and pressurizing valve 21, measuring tank is pressurizeed, open outlet valve 61 simultaneously, ethylene oxide can be extruded and come into operation;

When the needs bubbling, open suction valve 71 and bubbling valve 41, can carry out bubbling to material.

The described blowing and sweeping type ethylene oxide of present embodiment stores feedway, after ethylene oxide has been carried, be higher than under the measuring tank pressure condition at nitrogen pressure, open this nitrogen valve 72, purge remaining ethylene oxide in the pipeline, can purge the ethylene oxide that remains in the pipeline clean effectively, bubbling valve 41 goalkeeper's liquid phases communicate with gas phase, be higher than under the measuring tank pressure condition at nitrogen pressure, open valve and just can carry out bubbling, therefore compared with prior art have the following advantages:

The protection domain that need to prove this patent is not limited to the foregoing description, and those of ordinary skills do conventional change according to above-mentioned technology enlightenment, should all fall into the protection domain of this patent.
