Description

Side pipe antisludging agent filling system

Technical Field

The invention relates to the technical field of geothermal heating, in particular to a side pipe scale inhibitor filling system.

Background

The karst geothermal resources in the north China are rich, and the karst heat storage in the foggy mountain group is mostly exploited at present. In the process of karst heat storage and exploitation, the calcium carbonate scaling phenomenon is common. Some geothermal wells have serious underground calcium carbonate scaling phenomenon, which hinders daily production. Especially, calcium carbonate scaling in a pump pipe in the heating process often needs to be removed by stopping the pump, and the continuity of heating is seriously influenced. The scale inhibitor is filled from the pump pipe, so that the scale formation problem can be solved. However, the flow rate in the pump pipe is high, the filling pipeline is large in vibration and easy to wear, and the filling system is often broken down.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides a side pipe scale inhibitor filling system which is used for preventing calcium carbonate scaling of a pump pipe and an earth surface transportation pipeline. The scale inhibitor is filled through the side pipe, the problem of vibration and abrasion of a filling pipeline can be solved, and the pump lifting and the pump releasing of the deep-well pump do not influence a scale inhibitor filling system.

In order to achieve the purpose, the technical scheme of the invention is as follows:

a side pipe antisludging agent filling system comprises a pump chamber pipe which goes deep into the underground for operation, wherein a deep-well pump is arranged in the pump chamber pipe, one end of the pump chamber pipe is connected onto the deep-well pump, the pump chamber pipe extends upwards and partially extends out of the pump chamber pipe, and the other end of the pump chamber pipe is fixed at the upper end of the pump chamber pipe; and the side surface of the pump chamber pipe is connected with a side pipe, and the side pipe is used for supplying scale inhibitor.

The side pipe antisludging agent filling system is characterized in that the side pipe is connected with a filling pipeline on the ground, and the filling pipeline is connected with an antisludging agent box.

The side pipe antisludging agent filling system is characterized in that the side pipe antisludging agent filling system is provided with a regulating valve, a metering pump and a shutoff valve.

The side pipe antisludging agent filling system further comprises a liquid level meter arranged on the side surface of the antisludging agent box.

The side pipe antisludging agent filling system further comprises a liquid level meter with a scale for measuring the flow of the antisludging agent. Because the flow of the antisludging agent is small, the antisludging agent is difficult to accurately measure by a common flowmeter, and the method is simple and direct, low in cost and high in precision by adopting a liquid level meter with a scale.

The side pipe antisludging agent filling system is characterized in that the connecting position of the side pipe and the pump chamber pipe is positioned below the deep-well pump. The filling pipeline is connected with the side pipe, and the scale inhibitor is directly added from the side pipe. And the scale inhibition system and the filling pipeline are installed and maintained without lifting a deep well pump and a pump pipe. In addition, the maintenance of the deep-well pump and the pump pipe does not influence the scale inhibition pipeline system. The scale inhibition system can be constructed in the heating process, and does not lift or stop the pump, thereby not influencing the heating.

Compared with the prior art, the invention has the beneficial effects that: the scale inhibitor is filled through the side pipe, and an underground filling pipeline is not required to be additionally arranged, so that the cost can be saved, and the influence of the maintenance of a deep well pump and a pump pipe is avoided. The maintenance of the deep well pump and the pump pipe does not affect the scale inhibition pipeline system. The scale inhibition system can be constructed in the heating process, and does not lift or stop the pump, thereby not influencing the heating. Because the flow of the antisludging agent is small, the antisludging agent is difficult to accurately measure by a common flowmeter, and the method is simple and direct, low in cost and high in precision by adopting a liquid level meter with a scale.
