Embodiment 1

[0041] In the WSA wet acid plant, fans are often used to pressurize the gas. In the acid making device, the low-end interface of the blower is connected with the gas inlet pipeline, and the high-end interface of the blower is connected with the gas outlet pipeline, so as to transport the gas to the incinerator for combustion. At present, Roots blower is often used to pressurize coke oven gas. After running for a long time, impurities such as tar and dust in the coke oven gas will be deposited on the fan rotor. These deposited tar, dust, etc. will increase the running resistance of the Roots blower, which not only causes the body of the Roots blower to heat up, reduces the operation efficiency of the Roots blower, but also causes the rotor of the fan to vibrate greatly, thereby damaging the Roots blower.

[0042] In order to efficiently remove impurities such as tar in the Roots blower, this embodiment provides a cleaning method for the blower. The decontamination method can ...

Embodiment 2

[0059] The decontamination method for the fan provided in this embodiment is basically the same as the first implementation, the main difference is that in this embodiment, as image 3 As shown, step S5 is: if the second concentration value is not greater than the qualified concentration value, then add a sodium hydroxide solution with a concentration of a third concentration value in the cavity of the fan, the third concentration value is greater than the first concentration value, and repeat the steps S3-S4. Otherwise proceed to the next step. That is to say, directly adding high-concentration sodium hydroxide solution to the original solution can continue to clean the cavity of the Roots blower without repeated replacement of the cleaned mixed solution, which not only saves cleaning time, but also improves cleaning efficiency. Also avoid the waste of sodium hydroxide and water in the original solution.

Abstract

The invention belongs to the technical field of equipment cleaning, and discloses a cleaning method for a fan, which comprises the following steps: S1, blocking a low-end interface of the fan; s2, injecting a sodium hydroxide solution with a first concentration value into the fan until the solution submerges a rotor of the fan; s3, keeping for a first time; s4, detecting the concentration of the cleaned mixed solution; s5, if the concentration value is not greater than the qualified concentration value, emptying the fan cavity, and then repeating the steps S2-S4, otherwise, carrying out the next step; s6, a cavity of the fan is emptied, and the fan is washed with water; s7, washing is kept for the second time; s8, detecting the pH value of the low-end interface solution; s9, if the pH value is greater than the qualified pH value, repeating the steps S7-S8; otherwise, fan flushing is completed. According to the dirt removing method for the fan, impurities such as tar and dust on the rotor of the fan can be removed, operation is easy and convenient, the removing efficiency is high, and the effect is good.

Description

technical field [0001] The invention relates to the technical field of equipment cleaning, in particular to a cleaning method for fans. Background technique [0002] In the WSA wet acid plant, the Roots blower is often used to pressurize the gas to transport the gas to the incinerator for combustion. After running for a long time, impurities such as tar and dust carried in the gas will be deposited on the rotor of the Roots blower. The deposited tar and dust will increase the running resistance of the Roots blower, which not only causes the body of the Roots blower to heat up, reduces the operation efficiency of the Roots blower, but also causes the rotor of the Roots blower to vibrate greatly, thereby damaging the Roots blower. Ci fan. [0003] In order to prevent the accumulated dust, tar, etc. from damaging the rotor of the Roots blower, at present, the Roots blower is often disassembled regularly and disassembled into multiple parts; Erase; finally, reassemble the Roo...
