Description

Washing tower spraying and filtering system

Technical Field

The utility model relates to a scrubbing tower sprays filtration system belongs to gaseous purification treatment technical field.

Background

The source waste gas is neutralized by a spray water circulation system of the washing tower, but the spray head of the washing tower and the front end of the PH probe do not have a filtering device in daily work, so that the tail end is easy to be dirty and blocked, and the source waste gas cannot be timely found and treated after the dirty and blocked. And the cleaning of the blockage of the spray header needs to open the top access hole of the washing tower and the spray header is disassembled by people drilling, so that the cleaning is time-consuming, efficient and low in efficiency. In order to prevent the wind pressure from reducing and affecting the production when the access cover is opened, the maintenance of the washing tower must be carried out after the production is stopped. Therefore, the cleaning can not be carried out in time after the problem is found in time. Cause the equipment to work with illness, spray when the shower nozzle blocks up unevenly and can make the treatment waste gas efficiency descend. The PH probe is often polluted by flocculation algae, causes the measuring accuracy of the PH probe to be reduced to influence the dosage, reduces the neutralizing treatment effect of the source waste gas, and causes fluctuation of the outlet discharge concentration to influence the environmental protection. It takes much time to perform cleaning and calibration.

SUMMERY OF THE UTILITY MODEL

The utility model provides a scrubbing tower sprays filtration system, its aim at to spraying system's terminal shower nozzle can be blockked up by flocculation alga object often in daily work, leads to the shower nozzle water yield to reduce or even can't spray, and the PH probe also leads to the defect that measurement accuracy descends because flocculation sediment object parcel pollutes in addition.

The technical solution of the utility model is as follows: washing tower sprays filtration system, including water tank 1, spray pump 2, flange rubber soft 3, Y type filter 4, differential pressure transmitter 5, ball valve 6, check valve 7, PH probe 8, manometer 9, shower head 10, tower body 11 of connecing, 11 bottoms in the tower body are located to water tank 1, and in the water tank was located to 2 water inlets of spray pump, the delivery port was led to pipe and check valve 7 and is connected shower head 10, and PH probe 8, manometer 9 were located on tower body 11, be equipped with on 2 delivery port pipelines of spray pump that rubber soft 3, ball valve 6, Y type filter 4 and pressure transmitter 5 of connecing.

Spray pump 2, the spherical soft 3 that connects of rubber, differential pressure changer 5, check valve 7, ball valve 6 and Y type filter 4 and constitute a water pumping pipeline all the way, tower body 12 is equipped with two way water pumping pipelines, and normal use pipeline all the way is the spare pipeline all the way, but fast switch over to spare pipeline when normal use pipeline needs inspection or maintenance.

The utility model has the advantages that: the Y-shaped transparent filter is convenient to check and find blockage and is convenient to disassemble and wash, the spray head does not need to be disassembled and assembled after waiting for production halt, and the maintenance time and the cost are greatly reduced. The cleaning work for the pollution of the PH probe is reduced, the service life of the PH probe is prolonged, and the replacement cost is reduced. The flange rubber soft joint effectively reduces the vibration of the water pump and prevents sealing and water leakage.

Drawings

Figure 1 is the structure schematic diagram of the washing tower spray filtration system of the utility model.

In the attached drawing, 1 is a water tank, 2 is a spray pump, 3 is a flange rubber soft joint, 4 is a Y-shaped filter, 5 is a differential pressure transmitter, 6 is a ball valve, 7 is a check valve, 8 is a PH probe, 9 is a pressure gauge, 10 is a spray header, and 11 is a washing tower.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings.

Referring to the attached drawing 1, the washing tower mainly comprises a washing tower 11, a water tank 1, a spray pump 2, a flange rubber soft joint 3, a Y-shaped filter 4, a differential pressure transmitter 5, a ball valve 6, a check valve 7, a PH probe 8, a pressure gauge 9 and a spray head 10, wherein the liquid medicine in the water tank 1 is pumped and circulated by the washing tower spray pump 2, sprayed out from the spray head 10 at the top end through the check valve 7, enters the washing tower 11 for neutralization, and finally returns to the water tank 1. Wherein the pipeline water pressure can be remotely observed through the differential pressure transmitter 5 and can also be locally observed and referred to the pressure gauge 9 on site, and the pH value of the water quality in the water tank 1 is remotely monitored through the pH probe 8. When the spray header 10 of the washing tower does not discharge water or is about to be blocked, the alarm value of the differential pressure transmitter 5 in the control room is confirmed, and the washing tower is stopped to manually disassemble and clean the spray header 6 at the top.

A UPVC ball valve 6 and a transparent Y-shaped filter 4 are additionally arranged at the outlet of the spray pump 2 in a modified mode, the pipeline is used for standby, after the UPVC ball valve 6 is closed regularly, a probe of a differential pressure transmitter 5 and a filter element of the transparent Y-shaped filter 4 are inspected and cleaned, and the spray pump 2 is closed to be switched to be standby when the pressure is reduced or the filter is blocked. The cleaning and checking of the Y-shaped filter 4 do not affect the normal use of the washing tower 11, the Y-shaped filter 4 can be directly detached to clean the filter screen by closing the ball valve 6 after the spray pump 2 is switched to standby, and the spray pump 2 can be normally switched back after the cleaning is finished.

The problem that a spray head at the tail end of the washing tower is blocked and does not spray is solved by installing the transparent Y-shaped filter 4 at the outlet of the spray pump 2, and the cleanness and accurate metering of a PH probe 4 of the washing tower are guaranteed. The UPVC spherical rubber soft joint 3 is added at the outlet of the spray pump 2, so that the problems of large vibration and sealing water leakage during the operation of the water pump are solved.

The pressure transmitter 5 is added at the upper end of the Y-shaped filter 4, so that the problem that the blockage of the filter 4 and the spray header 10 cannot be found in time is solved, and an alarm is given when the pressure of the pipeline fluctuates.

The problem that the sealed not tight production of check valve 7 leaks after switching reserve spray pump has been solved to pressure transmitter 5's upper end increase UPVC ball valve 6, and pressure transmitter 5, Y type filter 4 and the maintenance of spray pump 2 of being convenient for, the beneficial effect of Y type filter installation is that the scrubbing tower shower nozzle sprays the equipartition and ensures that production treatment efficiency improves, the normal work of pH control dosing machine, makes exhaust emission up to standard accord with the environmental protection requirement.
