Device used for automatically measuring and compensating for water level

Abstract

The invention discloses a device used for automatically measuring and compensating for the water level. A double-chamber balance container is arranged outside of a boiler barrel. A separating plate is arranged in a shell. A communicating device is arranged in the shell. The boiler barrel is connected with a descending pipe which is provided with a control valve I and communicated with a condensation pipe. The condensation pipe is communicated with the bottom end of the shell. A steam pipe is provided with a control valve III and connected with the boiler barrel. The condensation pipe is provided with a control valve II. A control box is arranged outside the boiler barrel and the shell and connected with the control valve I, the control valve II and the control valve III. A pressure sensor I and a pressure sensor II are arranged in a cavity of the shell. The device not only can automatically and accurately measure the water level in a boiler, but also can automatically compensate for the water level according to the measurement result so that the water level in the boiler can keep at a reasonable height. Labor intensity is relieved, and work continuity and safety are improved.

Description

technical field [0001] The invention relates to a device, in particular to a device for automatically measuring and compensating water level. Background technique [0002] Thermal power generation is the main power generation method in my country. As one of the three major main equipments of thermal power plants, power plant boilers develop along with the development of my country's thermal power industry. In recent years, environmental protection and energy conservation have become an important direction for the structural adjustment of China's electric power industry. The thermal power industry has actively promoted the optimization and upgrading of the industrial structure under the policy of "upgrading the large and suppressing the small". To a certain extent, the upgrading of domestic thermal power equipment has been accelerated. The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel,...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem that the above-mentioned existing boiler cannot accurately measure the internal water level when it is working, and needs special personnel to guard it. Due to negligence, it is easy to cause dry burning of the boiler and cause serious consequences. Measurement and compensation device, the device can not only automatically measure the water level inside the boiler accurately, but also automatically compensate the water level according to the measurement results, so that the water level inside the boiler can be kept at a reasonable height, reducing labor intensity and continuous work The safety and security have been improved, and it solves the problem that the existing boiler cannot accurately measure the internal water level when it is working, and it needs special guards. Due to negligence, it is easy to cause the boiler to dry and cause serious consequences.
