Abstract
The utility model relates to an electric tracing formula cartridge filter, including cartridge filter, install the blowdown ball valve that the pipeline communicates, its characterized in that in cartridge filter's bottom: having an electric tracing area in the winding of cartridge filter's the lower part outside, having the asbestos heat preservation at dian ban tropical outside parcel, the tropical power cord of dianban is connected with explosion -proof switch after wearing out the asbestos heat preservation, in addition, the upper end of asbestos heat preservation is fixed by the metal ligature area of winding a week, and in addition, the tropical power of dian ban is in order to be as the criterion cartridge filter lower part shell temperature control 5 degrees - 50 degrees. The utility model discloses an install the electric tracing area additional bottom the filter, it is stifled effectually to prevent that the filter from taking place ice in winter to the normal air feed of assurance equipment.
Description
Technical field
The utility model belongs to the filter technical field in the various voltage adjusting devices of compressed natural gas, specifically a kind of electric heat tracing typeCartridge filter.
Background technology
The material and the environmental protection needs that day by day improve along with increasing and the people of China's natural gas exploration and development dynamics, in recent years,Long-distance Transmission Pipeline and large-scale door station and all kinds of pressure regulation metering equipment development are very rapid, and essential before pressure regulation meteringDevice be exactly filter, no matter especially cartridge filter, be the gas in access arrangement, or equipment pipe in we allCan not ensure that it is completely clean, is certain in equipment pipe have the impurity such as some iron filings, and also may exists in gasSome oil or water, not damaged in order to ensure pressure regulator, flowmeter normally to work, before gas enters them, weMust gas treatment is clean, impurity is disposed as much as possible, therefore we can arrange filter. When gas is through filteringAfter device, the filter core of filter interior can be by impurity interceptions such as oil, water, particles, and these impurity finally also can accumulate filterBottom. If but to winter, the impurity that these accumulate, especially water, be easy to freeze in filter interior, willFilter blowoff line blocks, of long duration, and equipment can be paralysed and be stopped air feed.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of electric heat tracing type cartridge filter.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of electric heat tracing type cartridge filter, comprises cartridge filter, and the row of pipeline communication is installed in the bottom of cartridge filterDirty ball valve, is characterized in that: the lower outside at cartridge filter is wound with electric-heating belt, is enclosed with in the outside of electric-heating beltAsbestos heat-insulation layer, the power line of electric-heating belt is connected with flame-proof switch after passing asbestos heat-insulation layer.
And the upper end of described asbestos heat-insulation layer is fixed by the metal binding band winding with one circuit.
And the power of electric-heating belt is as the criterion cartridge filter lower case temperature is controlled to 5 degree-50 degree.
And the thickness of described asbestos heat-insulation layer is at 2cm-2.5cm.
Advantage of the present utility model and good effect are:
The utility model, by installing electric-heating belt additional in filter bottom, can effectively prevent that filter from ice occurring in the winter time stifled,Thereby the normal air feed of the equipment of guarantee.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is implemented to be further described, following examples are descriptive, are not limited, can not limit protection domain of the present utility model with this.
A kind of electric heat tracing type cartridge filter, as shown in Figure 1, comprises cartridge filter 1, installs in the bottom of cartridge filterHave the Blowoff ball valve 5 of pipeline communication, innovative point of the present utility model is to be wound with electric tracing at the lower outside of cartridge filterBe with 3, be enclosed with asbestos heat-insulation layer 2 in the outside of electric-heating belt, the power line of electric-heating belt passes after asbestos heat-insulation layer and Anti-breakageClosing 4 connects.
In concrete enforcement of the present utility model, the upper end of described asbestos heat-insulation layer is fixing by the metal binding band 6 winding with one circuit,Metal binding band has not only been fixed asbestos heat-insulation layer, meanwhile, has also fixed electric-heating belt.
In concrete enforcement of the present utility model, the power of electric-heating belt is to be controlled at 5 degree by cartridge filter lower case temperature-50 degree are as the criterion.
In concrete enforcement of the present utility model, the thickness of described asbestos heat-insulation layer is at 2cm-2.5cm.
The utility model is that cartridge filter is carried out Insulation, prevents that filter bottom ice is stifled, ensures device security.
