Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of liquid level measurement in sludge thermal drying treatment, and particularly relates to a sludge drying carrier gas condensate tank. BACKGROUND

[0002] Sludge, as a product of sewage treatment, has multiple pollution characteristics such as organic pollution, pathogenic microorganism pollution, and heavy metal pollution, and must be effectively treated and disposed of, otherwise it will pose a great threat to the ecological environment. In December 2020, the annual sludge production in China was nearly 60 million tons (calculated at a moisture content of 80%), of which 70% of the sludge was not properly disposed of.

[0003] In a sludge thermal drying treatment facility, the sludge drying carrier gas condensate tank plays a crucial role. The sludge drying machine, heater, and condensate tank can form a heat source recovery system. In order to realize the detection of the carrier gas condensate liquid level in the condensate tank, the current liquid level detection is mainly realized by an ultrasonic level meter. The ultrasonic level meter is a digital liquid level instrument controlled by a microprocessor. In measurement, ultrasonic pulses are emitted by a sensor (transducer), and the sound wave is reflected by the liquid surface and received by the same sensor or an ultrasonic receiver. Through a piezoelectric crystal or magnetostrictive device, the sound wave is converted into an electrical signal, and the distance from the sensor to the surface of the measured liquid is calculated by the time between the emission and reception of the sound wave. Detecting the condensate liquid level in the condensate tank by the ultrasonic level meter facilitates the rational control of the liquid level. However, when using the ultrasonic level meter to measure the carrier gas condensate liquid level injected into the condensate tank, the condensate steam splashed out long-term interferes with the ultrasonic level meter probe, and a large amount of carrier gas condensate, condensate often covers the ultrasonic antenna, resulting in interference echo of the ultrasonic level meter and even death. The failure probability is high during work, which not only affects the normal operation of the production line, but also greatly affects the stable operation of the entire sludge drying system. At the same time, the maintenance amount of the instrument is large, which greatly reduces the production efficiency. In addition, because there is hydrogen sulfide gas and ammonia gas in the sludge drying carrier gas, the carrier gas condensate in the condensate tank is acidic or alkaline. After a long time of use, the acidic or alkaline carrier gas condensate can easily cause corrosion to the inner wall and internal components of the condensate tank, resulting in a reduction in the service life of the condensate tank.

The inner side surfaces of the fixed clamping block 19 and the movable clamping block 20 are provided with clamping grooves matched with the blowing pipe. The blowing pipe is clamped into the clamping grooves to ensure the stability of the blowing pipe after installation.

[0044] Referring to Figure 1 , Figure 6 As shown in the figure, the tank body 1 is provided with a neutralizing solution spraying mechanism. The neutralizing solution spraying mechanism comprises a corrosion-resistant metering pump 21 and a spray head 22. The corrosion-resistant metering pump 21 is fixedly arranged on the top of the tank body 1.

[0045] In use, the purge time and the moving direction of each structure during the purge operation are set by the PLC controller, one end of the first air guide telescopic pipe 11 is communicated with the high-pressure gas pipe or the gas generating device, when the probe position of the ultrasonic liquid level meter 2 needs to be purged, the PLC controller controls the first multi-stage electric telescopic rod 5 to drive the second multi-stage electric telescopic rod 6 and the lower support plate 9 to move as a whole to the side close to the ultrasonic liquid level meter 2, at the same time, the PLC controller synchronously controls the second multi-stage electric telescopic rod 6 to drive the lower support plate 9 to move upward, the first multi-stage electric telescopic rod 5 and the second multi-stage electric telescopic rod 6 cooperate with each other to clamp the purge pipe into the horn mouth at the probe position of the ultrasonic liquid level meter 2. When the second air guide telescopic pipe 12 moves left and right, the first air guide telescopic pipe 11 can automatically extend or retract according to the position of the second air guide telescopic pipe 12, when the lower support plate 9 moves up and down, the second air guide telescopic pipe 12 can also automatically extend or retract, the PLC controller controls the rotary cylinder 7 to start driving the purge pipe to reciprocate, at the same time, the PLC controller controls the air pipe electromagnetic valve to open, so that the high-pressure gas enters the purge pipe through the first air guide telescopic pipe 11, the second air guide telescopic pipe 12, the air guide end 14 and the flexible air guide pipe 13, and is sprayed out through the high-pressure air jet nozzle 18 on the purge pipe. When the purge pipe reciprocates, the inside and outside of the horn mouth at the probe position of the ultrasonic liquid level meter 2 are purged, since the flexible air guide pipe 13 is made of flexible material, when the flexible air guide pipe 13 contacts the support rod 10, the flexible air guide pipe 13 can deform, ensuring the flow of gas while enabling the rotary cylinder 7 to drive the purge pipe to rotate by 180°, thereby achieving comprehensive purging of the horn mouth at the probe position of the ultrasonic liquid level meter 2. After the purge operation, the PLC controller controls the first multi-stage electric telescopic rod 5 and the second multi-stage electric telescopic rod 6 to drive the lower support plate 9 to move and reset, so that the lower support plate 9 moves as a whole to the side below and beside the ultrasonic liquid level meter 2, thereby avoiding the influence of each structure on the liquid level detection of the ultrasonic liquid level meter 2, at the same time, the two neutral solution spraying mechanisms are controlled by the PLC controller, so that sodium hydroxide solution and hydrochloric acid solution are respectively sprayed into the tank body 1 through the two neutral solution spraying mechanisms, thereby neutralizing the condensed water to a neutral state, and avoiding the corrosion of acidic or alkaline condensed water on the internal components of the tank body 1 and subsequent process facilities.
