Boiler cleaning device

Abstract

The invention provides a boiler cleaning device. The boiler cleaning device comprises a small vehicle, a water storage tank, a chemical storage device and a cleaning tank. A first water inlet pipe isconnected with the right side of the water storage tank. A second water inlet pipe and a circulating water pipe are arranged on the cleaning tank, an on-line PH monitoring instrument is arranged on the cleaning tank, and the cleaning tank is connected to the water storage tank through the second water inlet pipe. Metering pumps are arranged on the chemical storage device, and the chemical storagedevice is connected to the cleaning tank through the metering pumps. A water outlet pipe is arranged on the left side of the cleaning tank, a boiler is connected with the right side of the water outlet pipe, a sewage drain pipe is arranged on the right side of the boiler, and the left side of the circulating water pipe is connected to the sewage drain pipe. Water valves are arranged on the first water inlet pipe, the second water inlet pipe, the water outlet pipe and the sewage drain pipe, the first water inlet pipe, the second water inlet pipe, the circulating water pipe and the sewage drainpipe are connected with a water suction pump, a temperature sensor is arranged on the boiler, and the metering pumps and the water suction pump are connected with a power device of the small vehicle.The boiler cleaning device can effectively remove the scale of the boiler and prolong the service life of the boiler.

Description

technical field [0001] The invention relates to the field of boiler cleaning equipment, in particular to a boiler cleaning device. Background technique [0002] Gas-fired hot water boiler is a common energy conversion device. After long-term use of the boiler, scale will be formed on the inner wall. When the boiler is scaled, the temperature of the heating surface will rise. If the boiler heating surface operates at ultra-high temperature for a long time, the metal material will Creep, bulging, and strength decline will occur, leading to tube bursts, endangering people's lives, and low heat exchange efficiency due to boiler fouling. Therefore, the boiler needs to be cleaned regularly to prevent accidents. [0003] The existing boilers are cleaned manually, which is labor-intensive and requires the transportation of a large number of cleaning equipment. Generally, the use of descaling agents needs to meet certain process conditions, such as water temperature and the PH value ...
