Description
Technical field
The utility model belongs to gas pipeline apparatus field, is specifically related to a kind of anti-icing stifled pressure governor with filtration.
Background technique
Pressure governor is a kind of important gas pipeline equipment, and the effect of this equipment converts high-pressure gas to low-pressure fuel gas, is just commonly using the requisite facility of gas.When cold snap, carry out blowdown can find a lot of liquid water to pipeline, mainly because of entrapped moisture in combustion gas, mercury dropped easily liquefies.When the combustion gas of band moisture enters into pressure governor pilot valve inside, due to pressure drop and cold weather, moisture easily condenses, pilot valve pressure tappings ice is caused to block up phenomenon, cause pressure governor not work, thus cause the blocking of gas pipeline, combustion gas stops, what affect user uses gas, causes larger negative effect.
Application number is in the Chinese patent of " CN201320144403.4 ", disclose the utility model patent that name is called " a kind of gas pipeline filter ", a kind of gas pipeline filter of this announcement, comprise that suction port and air outlet be connected on steam line its in establish the tank body of cavity, it is characterized in that cavity bottom is provided with sewage draining exit, in cavity, between suction port and air outlet, be provided with dividing plate.Although a kind of piping filter of this announcement is provided with filtrating equipment, there is interception result to most particulate matter, but can only a part be tackled for moisture, can not all tackle, some moisture can be through, and the ice that can not solve steam line completely blocks up problem.
Summary of the invention
For the technical problem of above-mentioned existence, the utility model provides a kind of anti-icing stifled pressure governor with filtration, the phenomenon that ice is stifled is easily there is with the pressure governor solving gas pipeline in cold weather, filtrating equipment and heating equipment was provided with before pressure governor, portion of water can be filtered, and heating gas, make the moisture in combustion gas be not easy to be gathered in pressure governor, prevent pressure governor generation ice from blocking up phenomenon.
A kind of anti-icing stifled pressure governor with filtration, comprise a pressure governor and gas pipeline, it is characterized in that, also comprise a filtrating equipment and heating equipment, described heating equipment is arranged between described pressure governor inlet end and described filtrating equipment, described filtrating equipment comprises filter cavity, filter plate, the dirty chamber of collection and blowdown valve, described filter plate is arranged in described filter cavity, described heating equipment comprises incubation chamber, thermal-protective coating, heating resistor and heat radiation pipe pad, described heat radiation pipe pad is wrapped on described gas pipeline, and described heating resistor is looped around on heat radiation pipe pad.
Further, described filter plate is for being obliquely installed, and concrete angle is 75 °.
Further, described filter cavity and the described dirt chamber that integrates are as spherical cavity.
Further, described thermal-protective coating is filled in incubation chamber.
The utility model is by installing filtrating equipment additional, can by combustion gas in pipeline with moisture filter a part, reduce the water content of combustion gas, can also by combustion gas with some dust and greasy dirt filter out, the dirty chamber of collection in filtrating equipment may be used for collecting the moisture and dirt that filter out, is more regularly cleared up by blowdown valve.Install heating equipment additional, heating resistor energising can be generated heat, and improve pipe temperature by heat radiation pipe pad, thus improve the temperature of combustion gas in pipeline, it can not condense through pressure regulator valve to make residual moisture, ensure that pressure governor also can normally run at low temperatures.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of structural representation of the anti-icing stifled pressure governor with filtration.
Embodiment
The utility model discloses a kind of anti-icing stifled pressure governor with filtration, filtrating equipment and heating equipment was provided with before pressure governor, portion of water can be filtered, and heating gas, the moisture in combustion gas is made to be not easy to be gathered in pressure governor, prevent pressure governor generation ice from blocking up phenomenon, ensure pressure governor normal operation at low ambient temperatures.
Below in conjunction with the accompanying drawing in the utility model, be clearly and completely described the technological scheme in the utility model, obviously, that described is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, belongs to the scope of the utility model protection.
Shown in Figure 1, a kind of anti-icing stifled pressure governor with filtration, comprise a pressure governor 1 and gas pipeline 2, it is characterized in that, also comprise a filtrating equipment 4 and heating equipment 3, described heating equipment 3 is arranged between described pressure governor 1 inlet end and described filtrating equipment 4, described filtrating equipment 4 comprises filter cavity 41, filter plate 42, collect dirty chamber 43 and blowdown valve 44, can by combustion gas in pipeline with moisture filter a part, reduce the water content of combustion gas, can also by combustion gas with some dust and greasy dirt filter out, the dirty chamber 43 of collection in filtrating equipment may be used for collecting the moisture and dirt that filter out, regularly cleared up by blowdown valve 44 again, described filter plate 42 is arranged in described filter cavity 41, described heating equipment comprises incubation chamber 31, thermal-protective coating 32, heating resistor 33 and heat radiation pipe pad 34, described heat radiation pipe pad 34 is wrapped on described gas pipeline 2, described heating resistor 33 is looped around on heat radiation pipe pad 34, heating resistor 33 energising can be generated heat, pipe temperature is improved by heat radiation pipe pad 34, thus the temperature of combustion gas in raising pipeline, it can not condense when pressure governor 1 to make residual moisture, ensure that pressure governor 1 also can normally run at low temperatures.Described filter plate 42 is for being obliquely installed, and concrete angle is 75 °.Described filter cavity 41 and describedly integrate dirty chamber 43 as spherical cavity.Described thermal-protective coating 32 is filled in incubation chamber 31.
Known by describing above, the utility model has the advantage of: before combustion gas enters pressure governor, just can carry out pretreatment to combustion gas, portion of water and heating raising fuel gas temperature is filtered respectively by crossing, make combustion gas by condensing during pressure governor, decrease ducted moisture, improve the working life of pipeline, prevent the generation of the situation of dying because ice blocks up.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
