Embodiment 1

[0030] Such as figure 1 and image 3 Shown, a kind of liquid-solid reaction process, liquid material (such as hydrochloric acid) and solid material (such as limestone) are added in the primary reactor and carry out neutralization reaction, and limestone inlet 11 is arranged on the top of described reactor 1 , at least one acid inlet 15 is arranged at the bottom of the reactor 1, at least one exhaust outlet 12 is arranged at the top of the reactor 1, and the liquid outlet 13 and the sewage outlet 14 are arranged at both ends of the reactor 1 On the side, the reactor 1 is also provided with a maintenance port; a plurality of exhaust ports 12 arranged on the top of the reactor 1 are distributed in a circle; the limestone feed port 11 is fed by a feed pipe, And the gas collection holes are evenly arranged on the feed pipe.

Embodiment 2

[0032] Such as figure 1 and image 3 Shown, a kind of liquid-solid reaction technology, liquid material (such as hydrochloric acid) and solid material (such as limestone) are respectively added in primary reactor and secondary reactor and carry out neutralization reaction, and the structure of reactor is the same as embodiment 1. The reaction liquid produced by the primary reactor is connected to the secondary reactor through pipelines. Hydrochloric acid enters from the bottom of the secondary reactor, and limestone is added from the top of the secondary reactor. At the same time, the reaction liquid produced by the primary reactor enters the secondary reactor, so that the reaction liquid can continue to react in the secondary reactor, increasing The reaction time makes the acid-base neutralization reaction more fully.

Embodiment 3

[0034] Such as figure 1 , figure 2 and image 3 Shown, a kind of liquid-solid reaction technology, liquid material (such as hydrochloric acid) and solid material (such as limestone) are respectively added in primary reactor 1 and secondary reactor to carry out neutralization reaction, the reaction that primary reactor produces The liquid enters the secondary reactor to continue the reaction, and the reaction liquid produced by the primary reactor and the secondary reactor enters the tertiary reactor 2 through the liquid inlet 24 to continue the reaction, and the top of the tertiary reactor 2 is provided with at least An exhaust port 21 , a liquid discharge port 22 and a sewage discharge port 23 are arranged on one side of the three-stage reactor 2 .

[0035] No new hydrochloric acid and limestone are added to the third-stage reactor, and the reaction liquid produced by the first two-stage reactor enters the third-stage reactor 2 to continue the reaction, increasing the reac...

Abstract

The invention discloses a liquid solid reaction process and a device thereof. Liquid materials and solid materials are added into at least one stage of reactor to perform neutralization reaction; the one-stage reactor comprises a solid material inlet and at least one acid inlet; the solid material inlet is formed in the top of the reactor; the at least one acid inlet is formed in the bottom of the reactor; at least one exhaust opening is formed in the top of the reactor; a liquid outlet and a pollution discharging opening are formed in the two sides of the reactor; an overhaul opening is also formed in the reactor. The process and the device have the advantages that the bottom acid inlet and upper part material inlet mode is used; the exhaust openings are positioned in the top of the rector and are in circumferential distribution; gas generated in the reaction can be conveniently exhausted. The acid inlet and the limestone feeding opening respectively use a feeding pipe form, so that the hydrochloric acid and the limestone can sufficiently take a reaction; the condition of incomplete local reaction of the hydrochloric acid and the limestone in conventional equipment can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a liquid-solid reaction process and a device thereof. Background technique [0002] At present, many chemical companies will produce a large amount of by-product hydrochloric acid waste liquid in the production process, and the treatment of hydrochloric acid waste liquid is a thorny problem for many enterprises. This technology uses cheap limestone to react hydrochloric acid waste liquid to generate calcium chloride liquid, which not only reduces the impact of hydrochloric acid waste liquid on the environment, but also further utilizes the waste liquid discharged from enterprises, which belongs to environmental protection, emission reduction and circular economic utilization projects , in line with the country's policy of promoting the development of circular economy. [0003] The existing technical method is to build a multi-stage concrete reaction tank, i...
