Description

Petroleum recovering well head warmer

Technical field

The utility model relates to the petroleum recovering device field, especially a kind of heating apparatus of petroleum recovering well head crude oil.

Background technology

In the recover petroleum process, crude oil during from underground extraction because of being subjected to the influence of stratum and air themperature, its temperature reduces gradually, especially winter, the crude oil speed that temperature reduces in the transmission course in pipeline was faster, thereby on the oil pipeline inwall of outer wellhead, be easy to occur the wax deposition phenomenon, cause the reduction of oil transportation efficient, in order to prevent the wax deposition phenomenon, the oil exploitation mining site generally uses heating furnace that the well head petroleum pipeline is heated at present, heating furnace is mainly water batch heater, and water batch heater is to add coil pipe in the water jacket, in the water jacket after the water heating with heat transferred coil pipe inner fluid, this heating furnace is for yielding poorly, intermittently fuel-displaced oil well is inapplicable, fluid is heated when fuel-displaced, and furnace heat does not distribute and do not go out when fuel-displaced, causes the water jacket internal pressure too high dangerous, the bad adjustment of combusting firepower, the efficiency of heating surface is low, the equipment heaviness.

Summary of the invention

In order to overcome the above-mentioned technical deficiency of existing oil pipeline warmer, the utility model provides a kind of petroleum recovering well head warmer, this warmer not only efficiency of heating surface height, save energy consumption, and security reliability height during to heating crude oil.

The technical scheme that its technical problem that solves the utility model adopts is: be provided with inlet valve, inlet valve links to each other with the lower end of one-level vertical tube, an end of pipe is connected on the upper end of one-level vertical tube and the one-level that is the ∩ font, the pipe other end of going up of one-level ∩ font then is connected with the upper end of secondary vertical tube, the lower end of this secondary vertical tube is connected with Guan Yiduan under the one-level that is the ∪ font, the other end of pipe then is connected with the lower end of three grades of vertical tubes under this ∪ font one-level, the upper end of these three grades of vertical tubes then links to each other with an end of pipe on the secondary ∩ font, the other end of pipe is connected with the upper end of level Four vertical tube on the secondary ∩ font, multistage vertical tube, last pipe, vertical tube, following pipe links to each other successively and forms the coil arrangement that is interconnected, the lower end of coil pipe afterbody vertical tube is connected with delivery valve, also be provided with a through hole on the tube wall of the upper end of every grade of vertical tube, electric heating tube vertically is inserted in the vertical tube inner chamber through this through hole, be sealed and matched between the upper end of electric heating tube and the through hole, the inlet oil temperature sensor is installed in the inlet valve, the oil outlet temperature sensor is installed in the delivery valve, inlet oil temperature sensor and oil outlet temperature sensor are connected with the signal input part of central control circuit respectively, and the signal output part of central control circuit is controlled the break-make of the power input of each electric heating tube respectively through a plurality of contacts of relay.The beneficial effects of the utility model are, efficiency of heating surface height, energy consumption are few, and have higher safety, and be simple in structure, can prevent petroleum pipeline wax deposition phenomenon effectively.
