Description
Technical field
The invention belongs to gas transmission and distribution technical field, be specifically related to a kind of combustion gas device for drying and filtering.
Background technology
In gas pressure regulating transmission & distribution process, in the time that the water content in combustion gas is higher, can reduce fuel gases calorific value on the one hand, there will be on the other hand " ice is stifled " phenomenon in winter, the i.e. inside of the inwall of pipeline or the pressure regulator of outdoor mounted in the open, moisture content in combustion gas is separated out with the form of freezing, thereby transmission & distribution pipeline is even stopped up in the normal work that affects pressure regulator, causes air feed to interrupt even causing security incident to downstream user.For this reason, enter small-bore pipeline or enter before pressure regulator in combustion gas, it is necessary that combustion gas is carried out once to effectively dry processing.If but use special drying equipment to be dried processing to combustion gas, need to invest drying equipment on the one hand, need the operation of drying equipment to carry out special management simultaneously, so the cost of gas transmission and distribution can be very high, and be only applicable to dry processing of combustion gas of large-scale gas transmission and distribution equipment.In order to overcome the above problems, our company transforms existing gas filter, succeeds in developing a kind of drying equipment that little, convenient management, operating cost are low, can conscientiously resolve a large amount of middle-size and small-size gas transmission and distribution equipment operating " ice is stifled " phenomenon that drops into.
Summary of the invention
The object of this invention is to provide a kind of reasonable in design, compact conformation, function combustion gas drying equipment extensive, easy to maintenance, be specially a kind of combustion gas device for drying and filtering.
For achieving the above object, the present invention by the following technical solutions:
A kind of combustion gas device for drying and filtering, by filter body, filter core, strainer cover, discharging valve and differential pressure gauge form, it is characterized in that filter body is integral type structure, include oral cavity, filter cartridge seat, UNICOM chamber, collection borneol, Rong Bing chamber, water leg and outlet plenum, described entrance cavity is positioned at the lower end of filter body, filter cartridge seat is established in entrance cavity top, it is barrel-shaped that filter core is cylinder, back-off holding is in filter cartridge seat, strainer cover center column is tight against filter core bottom, be assemblied in filter body upper end by screw, strainer cover, between filter body and filter core, surround UNICOM chamber, on filter body sidewall, be provided with a just outlet plenum to filter core sidewall, filter body inside sidewalls is established and is integrated borneol as strip projection, between Neighbor Set borneol and filter core, surround Rong Bing chamber, bottom, Rong Bing chamber connects establishes water leg, water leg assembling discharging valve, between entrance cavity and outlet plenum, establish the tube connector of assembling differential pressure gauge.
Described filter core comprises the stainless steel cylindrical drum with bottom surface, and cylinder barrel is established blast tube, and covered fiber filter material.
The material of described filter body is fine copper or aluminium, and described collection borneol is circumferentially uniform around filter core.
When assembling, the holding of filter core back-off is in filter cartridge seat, strainer cover center column is tight against filter core bottom and is assemblied in the upper end of filter body by screw, access upstream, filter inlet chamber burning line, combustion gas enters Rong Bing chamber through filter core, enter again UNICOM chamber, enter downstream user pipeline finally by outlet plenum.Its filter core cleaning is easy to also very convenient.
Because the material of manufacturing filter body is copper or aluminium, make filter body there is good heat conductivility, add that filter body inside sidewalls arranges many longitudinal strip collection borneol projections simultaneously, the similar orange of cross section cross section, pulp fraction is Rong Bing chamber, pulp interval is collection borneol, and this structure has further increased heat exchange area.In the time of winter, in the very low situation of outdoor temperature, gas-flow is in the time of Rong Bing chamber, moisture content in combustion gas is easy to become ice slush to separate out in the surface condensation of collection borneol, once there be ice to occur, synergy makes the moisture content in subsequent process combustion gas more easily build-up ice and concentrate in Rong Bing chamber, thereby reaches the effect of dry combustion gas.
Owing between the entrance cavity of filter and outlet plenum, differential pressure gauge being installed, in the time that the ice storage amount in Rong Bing chamber is on the increase, it is more and more narrower that blast tube can become, the show value of differential pressure gauge also simultaneously can be along with increase, in the time reaching certain numerical value, just can make the ice-out in Rong Bing chamber by the mode of external heat, by the discharging valve of water leg bottom, just can very easily the water in filter body be bled off, thereby make filter return to normal operating conditions.
Beneficial effect of the present invention is: can eliminate the possibility due to the icing pipeline blockage causing of the moisture content in combustion gas and the generation of pressure regulator fault completely, simultaneously by its unique ice-melt water distribution structure design, improve the convenience of maintaining, thereby greatly reducing the equipment operating cost in gas transmission and distribution process, is that the one of the single removal solid impurity of existing gas filter function is improved.
