Description

Spliced-inserted type coagulation reaction grid Technical Field The utility model relates to the technical field of water treatment, in particular to a spliced and inserted type coagulation reaction grid. Background In the field of water treatment, the coagulation stage plays a key role in removing suspended substances and colloid substances in water. To enhance flocculation, a number of techniques have been developed and applied. For example, "an adjustable gas-liquid multiphase vortex coagulation reaction grid (ZL 202222203906)" implements a gas-liquid multiphase vortex coagulation reaction by a specific structural design to promote flocculation. However, this technique has some drawbacks. The structure of the flocculation device is to be improved in the aspect of stability, and in the actual use process, when facing a complex water flow environment, the structure is easy to deform and the like, so that the persistence and stability of the flocculation effect are affected. And the grid has a complex porosity adjustment mode, limited flexibility, difficulty in quickly and conveniently changing the porosity according to different water quality and treatment requirements and insufficient adaptability. In addition, the structure is not optimized in material use, so that the whole weight is large, the installation difficulty is increased, and the transportation and installation cost is also increased. Besides the technology, the technology also comprises a small-mesh flocculation reaction technology, wherein the effluent of the secondary sedimentation tank after adding the flocculant is fully mixed by a mixer and then enters the small-mesh flocculation tank for flocculation reaction, suspended matters and phosphorus in the incoming water react to form alum flocs, and the alum flocs are clarified and removed by the sedimentation tank. The process utilizes the inertial effect generated by water flowing through the small-meshed grid plate to generate centrifugal inertial effect of high-proportion and high-strength micro-vortex behind the meshed, thereby solving the mass transfer problem of the hydrolysis product detail of the coagulant. However, the grid structure of the process has the problem of poor stability, is influenced by factors such as water flow impact and alum attachment in the long-term use process, is easy to damage and needs frequent maintenance. The hydrocyclone grid flocculation device forms vortex and shearing force through special structural design, promotes suspended particles in water to collide and agglomerate, and improves flocculation efficiency. The water inlet structure is designed to enable water flow to form strong rotational vortex, so that the shearing force and the micro-vortex proportion are enhanced, and the collision and condensation of tiny particles are promoted. However, the structure of the device is relatively complex, the manufacturing cost is high, the porosity is based on the structural design of specific honeycomb grid plates and the like, flexible adjustment is difficult, and the diversified water treatment requirements cannot be met. In view of the above, the existing water treatment flocculation related technology has various drawbacks in terms of stability, flexibility of porosity, material utilization and portability, and a new technical solution is needed to solve these problems. Disclosure of Invention The spliced coagulation reaction grid mainly comprises a plurality of crisscrossed pipes. The pipes are hollow pipes with consistent cross section, holes matched with the peripheral dimension of the longitudinal pipes are processed on the transverse pipes at the intersection points of the longitudinal pipes and the transverse pipes, and the longitudinal pipes are accurately inserted into the holes, so that a stable penetrating structure is formed. A plurality of groups of the penetrating structures are mutually staggered to form a net structure together. In an actual flocculation tank, when the water flow speed is greatly changed or the water flow direction is irregularly changed, the traditional grid may be locally loosened or even the whole structure is deformed, and the flocculation grid can bear larger water flow impact force due to the stable penetrating structure, and continuously and stably plays roles of increasing water flow turbulence and promoting flocculation. The flocculation grid is specially used for a flocculation tank in a water treatment coagulation stage, and the working principle of the flocculation tank is that a net structure formed by a penetrating structure is used for effectively increasing the turbulence degree of water flow so as to accelerate the flocculation process of colloid. The technical scheme adopted by the utility model for solving the problems is as follows: the spliced-type coagulation reaction grid is characterized by comprising a grid main body 3 and a frame 5, wherein the grid main body 3 is formed by vertically splicing a pl
