Precision treater for condensed water

Abstract

A precision treater for condensed water belongs to the technical field of water treatment equipment, and comprises a barrel, a barrel cavity partition plate, a group of lower cavity filter elements, a condensed water leading-in pipe, a spacer sleeve, a return water pipe, a back-wash pipe drive mechanism and a back-wash pipe, wherein the barrel is provided with an upper seal head and a lower seal head; the barrel cavity partition plate is arranged in a barrel cavity; a group of lower cavity filter element liquid outlet matching holes are formed in the barrel cavity partition plate; the lower cavity filter elements are arranged in the lower cavity of the barrel; the condensed water leading-in pipe is fixed with the bottom of the lower seal head; the spacer sleeve is fixed on one side of the upper seal head; a spacer sleeve water inlet connector extends from one side of the spacer sleeve; a one-way valve is arranged on the water inlet connector; one end of the return water pipe extends into the cavity of the spacer sleeve, and the other end thereof extends out of the barrel cavity; the back-wash pipe drive mechanism is arranged on the upper seal head; the upper end of the back-wash pipe extends into the cavity of the spacer sleeve, and the lower end thereof is supported in the center of the barrel cavity partition plate. The precision treater has the characteristics that a back-wash liquid spray arm is fixed at the lower end of the back-wash pipe, a spray arm opening is formed in the bottom of the back-wash liquid spray arm, the back-wash effect is ideal, the back-wash time is shortened, energy is saved, the outage time of the equipment is shortened, the structure is simplified, and the material is saved.

Description

technical field [0001] The invention belongs to the technical field of water treatment equipment, and in particular relates to a condensate polisher, which is used for the treatment of steam process condensate produced in industries such as petrochemical industry, oil refining industry, biomedicine chemical industry, power station and papermaking. Background technique [0002] The condensate mentioned above is also called condensate or surface condensate or even process condensate, accordingly, the condensate polisher mentioned above can also be called condensate polisher. Taking the chemical industry and oil refining industry as an example, a large amount of high-temperature steam is used as the energy source for heating various oil products in the production process. The steam is converted into condensed water after heat exchange, that is, from gas to liquid. If the condensed water is discharged as wastewater, it will cause a waste of precious water resources; and because ...

Problems solved by technology

[0007] However, the backwashing mechanism equipped with the above-mentioned "filter" has the following disadvantages: one, because the backwashing liquid from the backwashing liquid outlet is first sprayed into a certain chamber of the backwashing booster chamber in a horizontal state, Then the chamber makes the backwash liquid flow downward to backwash the filter element below the chamber, so the backwash liquid outlet cannot be directly aligned with the filter element to play the backwash function, that is to say, the backwash liquid is not correct. The filter element produces a direct injection effect, so the cleaning effect on the dirt attached to the filter element is insufficient, the cleaning time is long, the water source is wasted, and the time for the filter to return to the initial working state is affected; secondly, due to the long backwashing time, it is not conducive to saving support The power consumption of the motor of the backwashing mechanism; thirdly, the structure of the backwashing synergistic chamber is relatively complicated, for example, a group of partition plates need to be set at intervals on the barrel partition plate, and the group of radially distributed The partition plate and by means of the closure of the cover plate form a plurality of backwashing synergistic chambers on the cylinder cavity partition plate, so not only the manufacture is troublesome, but also the amount of raw materials used is large
