Description

A Boiler Ash Removal Ash Water System

technical field

The utility model relates to the electric power industry, in particular to a boiler ash removal and ash flushing water system.

Background technique

The ash removal and flushing water system of boilers in power plants operates as a separate system, that is, each furnace has two ash flushing water pumps, one for operation and one for standby; the ash flushing pump can provide water pumps with a certain pressure and flow rate, and is an auxiliary pump for power plant boilers. It is an important auxiliary equipment in the boiler system, with high pressure and large water supply, and is mostly used in the boiler water supply system of power plants. In the normal operation of the unit, two water pumps must be turned on to provide water for flushing the ash in the furnace, which increases the power consumption rate of the power plant, reduces the stability of the system, and increases the repair and maintenance costs of the equipment.

Utility model content

The technical problem to be solved by the utility model is to provide a boiler ash removal and ash flushing water system to solve the problems of poor stability and high power consumption rate of the existing boiler ash removal and ash flushing water system.

In order to solve the above-mentioned technical problems, the embodiment of the utility model provides a boiler ash removal and ash flushing water system, which includes two boilers, each of which is equipped with two ash flushing water pumps, each of which is connected to a water outlet pipe , the outlet pipe is connected to the boiler through a boiler water supply pipe, and the boiler water supply pipes communicate with each other through a connecting pipe.

Wherein, the ash flushing water pump is connected with a water inlet pipe, the water inlet pipe is provided with a solenoid valve, and the water inlet pipe is connected with the main water supply pipe.

Wherein, the main water supply pipe is connected to the forebay of the ash flushing water pump to provide water source.

Wherein, the outlet pipe is provided with a solenoid valve and a check valve.

Wherein, the boiler water supply pipe is provided with a pressure gauge or a pressure temperature gauge.

Wherein, the boiler water supply pipe is provided with a solenoid valve.

Wherein, the connecting pipe is provided with a solenoid valve.

Wherein, the outlet pipe is provided with a pressure gauge.

The beneficial effects of the above-mentioned technical solution of the utility model are as follows:

In the above scheme, by adding a connecting pipe, the original dual-use and two-standby gray water system is changed to a one-use and four-standby state, which improves the stability of the system, reduces the power consumption rate of the equipment, saves electricity, and facilitates the equipment maintenance and repair, reducing costs.

Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, the following will describe in detail with reference to the drawings and specific embodiments.

As shown in Figure 1 and Figure 2, the embodiment of the utility model provides a boiler ash removal and ash water system for the poor stability and high power consumption rate of the existing boiler ash removal and ash water system, including two boilers 10. Each boiler 10 is equipped with two ash flushing water pumps 1, each of which is connected to a water outlet pipe 2, and the water outlet pipe 2 is connected to the boiler 10 through a boiler water supply pipe 3, and the boiler The water supply pipes 3 communicate with each other through a connecting pipe 4 .

Wherein, the ash flushing water pump 1 is connected to a water inlet pipe 5, and an electromagnetic valve 6 is provided on the water inlet pipe 5 to control the water supply switch of the water inlet pipe 5. Valve 6; the water inlet pipe 5 is connected to the main water supply pipe 8, and the main water supply pipe 8 is connected to the forebay 11 of the ash flushing water pump to provide water source.

Further, each of the ash flushing water pumps 1 is connected to a water outlet pipe 2, and the water outlet pipe 2 is provided with a solenoid valve 6 and a check valve 7 to prevent water from flowing backward. The water outlet pipe 2 is connected to the boiler water supply pipe 3. The boiler 10 is connected, and a pressure gauge 9 is also provided on the outlet pipe 2 .

Wherein, the boiler water supply pipe 3 is provided with a pressure gauge 9 or a pressure temperature gauge 12 to monitor the water pressure and temperature of the boiler water supply pipe 3, and the boiler water supply pipe 3 is provided with a solenoid valve 6, when the boiler 10 appears When the situation, close the solenoid valve 6.

Further, the boiler water supply pipes 3 are connected through the connecting pipe 4, and the connecting pipe 4 is provided with a solenoid valve 6, so that the original dual-purpose and two-standby gray water system is changed into a one-use and three-standby state, so that One ash flushing water pump 1 completes the ash removal work of two boilers 10, which improves the stability of the system.

Wherein, the ash removal and ash flushing water system includes two boilers 10, and each boiler 10 is equipped with two ash flushing water pumps 1, and any one to four ash flushing water pumps 1 can be turned on according to actual needs, and it is guaranteed to complete two 10 boiler ash removal work can reduce the power consumption rate of the equipment, and at the same time, facilitate the maintenance of the equipment.

In the above scheme, by adding a connecting pipe, the original dual-use and two-standby gray water system is changed to a one-use and three-standby state, which improves the stability of the system, reduces the power consumption rate of the equipment, saves electricity, and facilitates the equipment maintenance and repair, reducing costs.
